Overview

Trulia is redefining the home search experience for consumers and changing the way that real estate professionals build their businesses. Our marketplace, delivered through the web and mobile applications, gives consumers powerful tools to research homes and neighborhoods and enables real estate professionals to efficiently market their listings and attract new clients. We believe we deliver the best home search experience by combining our superior user interface with our comprehensive database of real estate properties, local insights, and user-generated content. We offer free and subscription products that provide real estate professionals with access to transaction-ready consumers and help them enhance their online presence. In the six months ended June 30, 2012, we had 22.0 million monthly unique visitors. As of June 30, 2012, we had more than 360,000 active real estate professionals in our marketplace, 21,544 of whom were paying subscribers.

We empower consumers to make more informed housing decisions by delivering the “inside scoop” on homes, neighborhoods, and real estate professionals through an intuitive and engaging user experience. Our large, continually refreshed, and searchable database contains more than 110 million properties, including 4.5 million homes for sale and rent. We supplement listings data with local information on schools, crime, and neighborhood amenities to provide unique insights into each community. In addition, we harness rich, insightful user-generated content from our active community of contributors, which includes consumers, local enthusiasts, and real estate professionals. With more than 5 million unique user contributions, we believe we have the largest collection of user-generated content on homes, neighborhoods, and real estate professionals.

We enable real estate professionals to better promote themselves and their listings and connect with transaction-ready consumers through our online and mobile marketing products. Our free products allow real estate professionals to build their personal brand by creating an online profile, contributing content to our marketplace, leveraging social media for endorsements, and establishing their presence through mobile features such as “check-ins.” Our subscription products enable real estate professionals to increase their visibility, promote their listings in search results, target mobile users, and generate more highly qualified leads from our large audience of transaction-ready consumers. We believe that our audience is highly motivated and ready to purchase homes, as supported by our surveys conducted between November 2011 and May 2012 in which 76% of over 290,000 respondents contacting real estate professionals through our marketplace indicated that they are planning to move in the next six months, and in which almost half of over 210,000 respondents stated that they are pre-qualified for a mortgage. We believe that the combination of our compelling solution with our transaction-ready audience results in a high return on investment for real estate professionals who purchase our subscription products.

We benefit from powerful network effects and a vibrant user community. Consumers contribute content by posting questions, reviewing neighborhoods, and writing agent recommendations. Real estate professionals, seeking to connect with our consumers, engage in our community by sharing local knowledge, answering consumers’ questions, and contributing content to our marketplace. The breadth and quality of user-generated content contributed to our marketplace has helped to build our brand, deepen the engagement of our existing users, and attract more users.

We are a leading mobile platform for the home search process and mobile devices are increasingly critical to consumers and real estate professionals. We have introduced iPhone, iPad, Android, and Kindle applications that provide tailored mobile experiences, which has led to rapid growth in mobile use of our solution. In the six months ended June 30, 2012, we had over 4.3 million mobile monthly unique visitors, an increase of 176% over the same period in 2011. In addition, our mobile users are more likely than our web users to contact real estate professionals through our marketplace.

Our online marketplace is experiencing rapid growth. Monthly unique visitors to our marketplace increased from 5.0 million in the six months ended June 30, 2009 to 22.0 million in the six months ended June 30, 2012, and our subscribers increased from 2,398 as of June 30, 2009 to 21,544 as of June 30, 2012. We generate revenue primarily from sales of subscription products to real estate professionals. We also generate revenue from display advertising sold to leading real estate and consumer brand advertisers seeking to reach our attractive audience. In the years ended December 31, 2009, 2010, and 2011, and the six months ended June 30, 2012, we generated revenue of $10.3 million, $19.8 million, $38.5 million, and $29.0 million, respectively. During the same period, we had net losses of $7.0 million, $3.8 million, $6.2 million, and $7.6 million, respectively.

Industry and Challenges

The residential real estate industry, which we estimate accounts for more than a trillion dollars in annual spending in the United States, is undergoing a profound transformation. Technology is changing the way that consumers search for homes and the way in which real estate professionals attract clients and build their businesses. In addition, the recent unprecedented downturn in the housing market is causing real estate professionals to seek more effective ways to market themselves and achieve a greater return on their marketing investment. These trends present significant opportunities to capitalize on shifts in behavior.

Historically, consumers lacked readily available access to detailed and comprehensive information essential to making housing decisions, relying instead on disparate sources of information such as real estate professionals, local newspapers, and word of mouth. Over time, more information has become available online and, as a result, the Internet has become a primary source of research for housing decisions. According to a November 2011 survey by the National Association of Realtors, a trade organization for real estate professionals, 88% of home buyers used the Internet to research homes. Additionally, the use of mobile devices for home searches has become more prevalent. According to a 2012 survey by The Real Estate Book, a real estate website, 52% of respondents reported using a mobile device to look for homes, with 85% of non-users stating that they would consider using a mobile device for their next search.

As consumers increasingly research homes online, real estate professionals are shifting their marketing expenditures online to reach prospective clients. While initially these real estate professionals focused their spending on email, search, and creating websites with listings, now these professionals are increasingly using online real estate marketplaces to generate leads.

With technology driving the home search process online, consumers, real estate professionals, and advertisers face distinct challenges. Consumers are challenged to effectively compile and use fragmented information, gain local insights, and obtain information on the go. Real estate professionals are challenged to reach today’s online consumers, target the right leads, manage their businesses while on the go, and optimize their marketing spend. Advertisers are challenged to efficiently reach the right consumers while maximizing the effectiveness of their advertising.

Market Opportunity

We believe that there are significant opportunities to address the challenges faced by consumers, real estate professionals, and advertisers. Borrell Associates, Inc., an advertising research and consulting firm, estimated in an August 2012 industry paper that $23.7 billion would be spent in 2012 on real estate-related marketing in the United States. According to a November 2011 survey by the National Association of Realtors, 88% of home buyers used the Internet to research homes. However, according to the Borrell Associates report, only 55% of the real estate marketing dollars in the United States were projected to be spent online in 2012. We believe that there is a disconnect between where marketing dollars are spent and where consumers research homes. Therefore, we expect that real estate-related marketing spend will continue to migrate online from traditional channels.

The Trulia Marketplace

Our marketplace provides the following key benefits for consumers, real estate professionals, and advertisers:

Key benefits for consumers

•

Large, continually refreshed, searchable database of homes for sale and rent. We provide consumers with access to a large, continually refreshed, and searchable database of properties. We enable consumers to customize their searches with property-specific filters to obtain up-to-date listings that are rich with property facts, price, and sale data.

•

Anytime and anywhere access. Our marketplace is accessible anytime and anywhere on the web and on major mobile platforms. Since the introduction of our first mobile application in 2008, mobile use of our marketplace has grown rapidly.

Key benefits for real estate professionals

•

Broad reach to transaction-ready consumers. We provide real estate professionals the ability to connect with our large audience of transaction-ready consumers at scale on the web and through our mobile applications. We believe that a large portion of consumers using Trulia do not use other real estate websites, and that this enables real estate professionals on Trulia to effectively identify and market themselves to consumers that they cannot find anywhere else.

•

Products that boost presence and deliver high-quality leads. Our free products enable real estate professionals to create and manage an online profile, promote their personal brand with consumers by contributing content to our marketplace, and leverage social media for endorsements. Our subscription products enable real estate professionals to boost their visibility, promote their listings in search results, and generate more high-quality leads from potential home buyers.

•

Anytime and anywhere access to critical information and tools. We offer mobile applications designed specifically for real estate professionals to take their business on the go. Using our mobile applications, real estate professionals can access critical information that they need to conduct their business, including listings details, contacts, driving directions, and local information about neighborhoods.

•

Significant return on investment. We believe that our subscription products deliver a high return on investment to real estate professionals.

Key benefits for advertisers

•

Attractive audience. We believe our audience is highly attractive to consumer brand advertisers. A substantial portion of our audience is either college educated, has a household income above $75,000, or is in the 25 to 54 age group. U.S. consumers with these characteristics tend to spend more of their annual income on home maintenance, insurance, household furnishings, apparel and services, and entertainment than the average consumer, according to the Bureau of Labor Statistics 2010 Consumer Expenditure Survey, which makes our audience attractive for consumer brand advertisers.

•

Display advertising products that efficiently reach target consumers. We enable our advertisers to reach segments of our audience that are attractive to them. Advertisers benefit from improved reach, impact, relevancy, and measurement of their marketing campaigns in our marketplace.

Our Strengths

We believe that our competitive advantage reflects the following strengths:

•

We deliver the “inside scoop.” We are one of the leading online real estate marketplaces and provide consumers with powerful tools and unique content that together deliver valuable insights into homes, neighborhoods, and real estate professionals. For example, our crime heat maps provide consumers with a view into neighborhood safety and our Facebook integration gives consumers recommendations on real estate professionals from people in their social network. Through our Trulia Voices forum, we also provide consumers with local content from our community of contributors, including consumers, local enthusiasts, and real estate professionals.

•

Superior products and user experience. We believe we have the best products in the industry for consumers and real estate professionals. We invest significant resources into technology development and product design to create a superior user interface that provides compelling features and rich functionality for our users.

•

Large, differentiated, transaction-ready audience. Our website and mobile applications have attracted 22.0 million monthly unique visitors in the six months ended June 30, 2012 and, based on data from comScore, Inc., a marketing research company, a significant portion of our visitors do not visit our primary competitors’ websites. For instance, according to comScore, during each month in 2011 and in each of the six months ended June 30, 2012, more than 50% of our audience did not visit Zillow.com. We believe that our audience is highly motivated and ready to purchase homes, as supported by our surveys conducted between November 2011 and May 2012 in which 76% of over 290,000 respondents contacting real estate professionals through our marketplace are planning to move in the next six months, and in which almost half of over 210,000 respondents stated that they are pre-qualified for a mortgage.

•

Strong mobile monetization. We believe that we are one of the few companies that is monetizing its mobile products at a higher rate than web products. Since we launched our subscription product for mobile devices in May 2012, we have sold this product at prices that yield a higher average monthly revenue per subscriber than our subscription products that are not focused on mobile devices. In addition, our users are more likely to contact real estate professionals through our mobile applications than our website.

•

Better ROI for real estate professionals. We believe our subscription products provide compelling value and a better return on investment than other marketing channels. On average, paying subscribers receive more than five times the number of monthly leads compared to real estate professionals who only use our free products.

•

Powerful network effects driven by unique content. We benefit from a self-reinforcing network effect that helps build our brand, drives user engagement in our marketplace, and attracts more users to our website and mobile applications. Consumers post questions in our marketplace, attracting real estate professionals who add more content by answering these questions, which in turn attracts more consumers to our marketplace.

•

Big data and analytics platform. We employ proprietary advanced analytics and heuristics capabilities to aggregate, filter, and analyze large amounts of data from disparate sources that we have cultivated over the years. Our expertise in handling large amounts of externally-sourced data and combining it with user activity data collected from our marketplace allows us to improve the user experience by developing innovative new tools and new functionality.

Our Strategy

Our goal is to build the leading online real estate marketplace. We intend to focus on the following key strategies in pursuit of our goal:

•

Expand our audience and increase user engagement. We intend to grow our large, transaction-ready audience by continuing to offer superior products for consumers. We plan to continuously enhance and refresh our database of homes, partner with third parties to add new and relevant local content, and encourage our users to contribute useful content. We also plan to develop new features and tools that deepen our users’ engagement with our website and mobile applications, and to promote and foster interaction in our vibrant user community.

•

Grow the number of real estate professionals in our marketplace. We intend to further penetrate the large base of more than 2.8 million real estate professionals in the United States by communicating the value proposition of our free and subscription products, growing our audience of transaction-ready consumers, and creating additional products.

•

Increase revenue. We plan to increase our revenue by selling more subscription and advertising products and by optimizing our pricing.

•

Increase brand awareness. We have built a leading real estate and consumer brand with limited marketing spend to date. We plan to continue to grow our brand by providing our users with superior and innovative products.

•

Pursue adjacent opportunities. We plan to pursue opportunities in a number of large adjacent markets, such as rentals, mortgages, home improvement, and agent tools, and to expand our business internationally.

Risks Associated with Our Business

•

We have a limited operating history in an evolving industry, which makes it difficult to evaluate our future prospects.

•

We have a history of losses and we may not achieve or maintain profitability in the future.

•

Real estate professionals may not continue to subscribe to our products, we may be unable to attract new subscribers, and we may not be able to optimize the pricing of our products.

•

Advertisers may reduce or end their advertising spending with us or we may be unable to attract new advertisers.

To analyze our business performance, determine financial forecasts, and help develop long-term strategic plans, we review the following key business metrics:


	Year Ended December 31,						Six Months Ended June 30,
	2009		2010		2011		2011		2012
Monthly unique visitors (in thousands)		5,206		7,935		14,776		13,407		22,030
Mobile monthly unique visitors (in thousands)		30		484		2,088		1,592		4,389
New contributions to user-generated content (in thousands)		507		1,386		1,991		1,049		1,397
Total subscribers (at period end)		4,667		10,070		16,849		14,766		21,544
Average monthly revenue per subscriber ($)		47		80		110		91		140

We count a unique visitor the first time a computer or mobile device with a unique IP address accesses our website or our mobile applications during a calendar month. If an individual accesses our website or mobile applications using different IP addresses within a given month, the first access by each such IP address is counted as a separate unique visitor. We calculate our monthly unique visitors based on the monthly average over the applicable period. Our number of monthly unique visitors includes mobile monthly unique visitors.

For an explanation of our key business metrics, see the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Overview—Key Business Metrics.”

Non-GAAP Financial Measures

Adjusted EBITDA is a financial measure that is not calculated in accordance with generally accepted accounting principles in the United States, or GAAP. We define Adjusted EBITDA as net loss adjusted to exclude interest income, interest expense, depreciation and amortization, change in fair value of warrant liability, and stock-based compensation. Below, we have provided a reconciliation of Adjusted EBITDA to our net loss, the most directly comparable financial measure calculated and presented in accordance with GAAP. Adjusted EBITDA should not be considered as an alternative to net loss or any other measure of financial performance calculated and presented in accordance with GAAP. Our Adjusted EBITDA may not be comparable to similarly titled measures of other organizations because other organizations may not calculate Adjusted EBITDA in the same manner as we calculate the measure.

We include Adjusted EBITDA in this prospectus because it is an important measure upon which our management assesses our operating performance. We use Adjusted EBITDA as a key performance measure because we believe it facilitates operating performance comparisons from period to period by excluding potential differences primarily caused by variations in capital structures, tax positions, the impact of depreciation and amortization expense on our fixed assets, changes related to the fair value remeasurements of our preferred stock warrant, and the impact of stock-based compensation expense. Because Adjusted EBITDA facilitates internal comparisons of our historical operating performance on a more consistent basis, we also use Adjusted EBITDA for business planning purposes, to incentivize and compensate our management personnel, and in evaluating acquisition opportunities. In addition, we believe Adjusted EBITDA and similar measures are widely used by investors, securities analysts, ratings agencies, and other parties in evaluating companies in our industry as a measure of financial performance and debt-service capabilities.

Our use of Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:

•

Adjusted EBITDA does not reflect our cash expenditures for capital equipment or other contractual commitments;

•

Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and Adjusted EBITDA does not reflect capital expenditure requirements for such replacements;

•

Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;

•

Adjusted EBITDA does not reflect the interest expense or the cash requirements necessary to service interest or principal payments on our indebtedness; and

•

Other companies, including companies in our industry, may calculate Adjusted EBITDA measures differently, which reduces their usefulness as a comparative measure.

In evaluating Adjusted EBITDA, you should be aware that in the future we will incur expenses similar to the adjustments in this presentation. Our presentation of Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by these expenses or any unusual or non-recurring items. When evaluating our performance, you should consider Adjusted EBITDA alongside other financial performance measures, including our net loss and other GAAP results.

The following table presents a reconciliation of Adjusted EBITDA to our net loss, the most comparable GAAP measure, for each of the periods indicated:

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below, together with all of the other information in this prospectus, before making a decision to invest in our common stock. The risks and uncertainties described below may not be the only ones we face. If any of the risks actually occur, our business, financial condition, operating results, and prospects could be materially and adversely affected. In that event, the trading price of our common stock could decline, and you could lose part or all of your investment.

We have a limited operating history in an evolving industry, which makes it difficult to evaluate our future prospects and may increase the risk that we will not be successful.

We have a limited operating history in an evolving industry that may not develop as expected. Assessing our business and future prospects is challenging in light of the risks and difficulties we may encounter. These risks and difficulties include our ability to:

If the demand for residential real estate information online does not develop as we expect, or if we fail to address the needs of consumers, real estate professionals, or advertisers, our business will be harmed. We may not be able to successfully address these risks and difficulties, which could harm our business and cause our operating results to suffer.

We have a history of losses and we may not achieve or maintain profitability in the future.

We have not been profitable on a quarterly or annual basis since we were founded, and as of June 30, 2012, we had an accumulated deficit of $43.8 million. We expect to make significant future investments in the development and expansion of our business which may not result in increased revenue or growth. In addition, as a public company, we will incur significant legal, accounting, and other expenses that we did not incur as a private company. As a result of these increased expenditures, we will have to generate and sustain increased revenue to achieve and maintain future profitability. While our revenue has grown in recent periods, this growth

may not be sustainable and we may not achieve sufficient revenue to achieve or maintain profitability. We may incur significant losses in the future for a number of reasons, including slowing demand for our products, increasing competition, weakness in the residential real estate market, as well as other risks described in this prospectus, and we may encounter unforeseen expenses, difficulties, complications and delays, and other unknown factors. Accordingly, we may not be able to achieve or maintain profitability and we may continue to incur significant losses in the future, and this could cause the price of our common stock to decline.

If real estate professionals do not continue to subscribe to our products, or we are unable to attract new subscribers, our business and operating results would be harmed.

We rely on subscriptions purchased by real estate professionals to generate a substantial portion of our revenue. Subscriptions accounted for 32%, 47%, 58%, and 68% of our revenue in 2009, 2010, 2011, and the six months ended June 30, 2012, respectively. We generally offer subscriptions for periods between one month to 12 months, with most real estate professionals preferring to subscribe for periods shorter than 12 months.

Our ability to attract and retain real estate professionals as subscribers, and to generate subscription revenue, depends on a number of factors, including:

A key focus of our sales and marketing activities has been to further penetrate the large base of more than 2.8 million real estate professionals in the United States. As of June 30, 2012, we had more than 360,000 active real estate professionals in our marketplace, and 21,544 total subscribers. We spend a considerable portion of our operating expenses on sales and marketing activities. Our sales and marketing expenses were our largest operating expenses in 2011 and the six months ended June 30, 2012. Sales and marketing expenses reflect many of the costs that we incur in acquiring new subscribers and retaining existing subscribers, and we expect that sales and marketing expenses will continue to increase in absolute dollars as we seek to grow the number of subscribers in our marketplace. If we are unable to increase the number of total subscribers in our marketplace, our revenue may not grow and our operating results could suffer.

Real estate professionals may not continue to subscribe with us if we do not deliver a strong return on their investment in subscriptions, and we may not be able to replace them with new subscribers. In addition, real estate professionals sometimes do not renew their subscriptions with us because of dissatisfaction with our service. If subscribers do not renew their subscriptions with us with the same or higher subscription fees, or at all, or we are unable to attract new subscribers, our business and operating results would be harmed.

Further, although a majority of our revenue in 2011 and the six months ended June 30, 2012 was generated from subscriptions purchased by real estate professionals, we cannot be certain that subscribers will renew their subscriptions with us and that we will be able to achieve the same or higher amounts of subscription revenue in the future. Historically, we have not focused on renewal rate as an important metric for our business. Moreover, we believe renewal rate may be a misleading metric for our business as a result of seasonality, the fact that many real estate professionals only purchase subscriptions for a limited period of time as part of their advertising campaigns, and other factors.

In addition, if we need to reduce our subscription fees due to competition, our business, operating results, financial condition, and prospects would suffer if we are unable to offset any reductions in our fees by increasing our number of consumers and advertisers, reducing our costs, or successfully developing and deploying new features on a timely basis.

If we are not able to optimize our pricing and increase our average revenue per subscriber, we may not be able to grow our revenue over time.

Our ability to grow revenue depends, in part, on our ability to optimize pricing and increase average monthly revenue per subscriber over time. Since launching our first subscription product in 2007, we have continued to expand our products and optimize pricing of our products. In 2009, 2010, 2011, and the six months ended June 30, 2012, our average monthly revenue per subscriber was $47, $80, $110, and $140, respectively. As we continue to optimize our pricing, real estate professionals may not accept these new prices, which may harm our business and growth prospects.

If advertisers reduce or end their advertising spending with us, or if we are unable to attract new advertisers, our business and operating results would be harmed.

Display advertising accounted for 68%, 53%, 42%, and 32% of our revenue in 2009, 2010, 2011, and the six months ended June 30, 2012, respectively. Our advertisers can generally terminate their contracts with us at any time or on very short notice. Our ability to attract and retain advertisers, and to generate advertising revenue, depends on a number of factors, including:

We may not succeed in capturing more spending from advertisers if we are unable to demonstrate to advertisers the effectiveness of advertising in our marketplace as compared to alternatives, including traditional offline advertising media such as newspapers and magazines.

If advertisers reduce or terminate their advertising spending with us and we are unable to attract new advertisers, our revenue, business, operating results, and financial condition would be harmed. For example, although we experienced sequential increases in media revenue during each of the eight quarters ended December 31, 2011, the growth in our media revenue slowed during the year ended December 31, 2011 and our media revenue decreased in the three months ended March 31, 2012 relative to the three months ended December 31, 2011. The primary reason for the decrease in media revenue during the three months ended March 31, 2012 was the loss of a significant customer which declared bankruptcy. In our display advertising business, we also have a limited ability to replace the loss of revenue resulting from the loss of a customer during a particular quarter because of the significant time required to secure an alternative advertiser for such advertising inventory, run the alternative advertising campaign on our marketplace, and satisfy our revenue recognition criteria from such campaign. As a result, the loss of a customer during a quarter could result in our inability to replace the lost revenue from such customer within that quarter and, therefore, we will sometimes encounter variances in our media revenue.

If we cannot obtain comprehensive and accurate real estate listing information, our business will suffer.

Our offerings are based on receiving current and accurate real estate listing data. We depend on, and expect to continue to depend on, relationships with various third parties to provide this data to us, including real estate listing aggregators, multiple listing services, real estate brokerages, apartment management companies, and other

third parties. Many of our agreements with our listing sources are short-term agreements that may be terminated with limited or no notice. If our relationship with one or more of these parties is disrupted, the quality of the experience we provide to users would suffer.

We currently depend on a listing aggregator to provide us with a substantial portion of the unique listings in our database. While these listings are available from their original sources, it would take substantial time and effort for us to aggregate these listings from all of the original sources. Therefore, if the agreement with our largest listing aggregator is terminated, we may not be able to fully replace the listings in a timely manner or on terms favorable to us, or at all, which would adversely affect our business and operating results. In addition, as real estate brokers typically control the distribution and use of their listings, our business could suffer if real estate brokers withheld their listings from us. From time to time in the past, real estate brokers have refused to syndicate their listings to us, and we cannot assure you this will not happen in the future. If real estate brokers refuse to syndicate listings to us, the quality of our products would suffer due to the decline of timely and accurate information, which could adversely affect our business and operating results.

If use of our mobile products does not continue to grow or we are not able to successfully monetize them as we expect, our operating results could be harmed and our growth could be negatively affected.

Our future success depends in part on the continued growth in the use of our mobile products by our users and our ability to monetize them. During 2011 and in the six months ended June 30, 2012, our mobile products accounted for 14% and 20% of our total traffic, respectively. We currently monetize our mobile offerings through our Trulia Mobile Ads subscription product for real estate professionals and through our mobile website, m.trulia.com. We monetize our mobile applications principally through our Trulia Mobile Ads subscription product through which real estate professionals can purchase local advertising on our mobile applications and our mobile website by zip code or city and by share of a given market. We monetize our mobile website through the sale of display advertisements and we also provide our subscribers rotational placement in a local lead form that appears on certain pages of our mobile website. The use of mobile technology may not continue to grow at historical rates, and consumers may not continue to use mobile technology for real estate research. Further, mobile technology may not be accepted as a viable long-term platform for a number of reasons, including actual or perceived lack of security of information and possible disruptions of service or connectivity. In addition, traffic on our mobile applications may not continue to grow if we do not continue to innovate and introduce enhanced products on mobile platforms, or if users believe that our competitors offer superior mobile products. The growth of traffic on our mobile products may also slow or decline if our mobile applications are no longer compatible with operating systems such as iOS or Android or the devices they support. Additionally, real estate professionals and advertisers may choose to devote less of their spending to target mobile users for a number of reasons, including a perceived lack of effectiveness of display advertising on mobile devices. Although we have seen strong results in our mobile product monetization efforts with the launch of Trulia Mobile Ads in May 2012, these are early results with only a few months of data and we cannot assure you that we will continue to monetize our mobile products as effectively in the future. If use of our mobile products does not continue to grow, or if real estate professionals or advertisers decrease their spending on our mobile products, our business and operating results could be harmed.

If we do not continue to innovate and provide useful products, we may not remain competitive, and our business and financial performance could suffer.

Our success depends in part on our ability to continue to innovate. This is particularly true with respect to mobile applications, which are increasingly being used by our audience. Our competitors regularly enhance their offerings and create new offerings for consumers, real estate professionals, and others involved in the residential real estate industry. If we are unable to continue to offer innovative products or to keep pace with our competitors’ offerings, our business and operating results will suffer.

We rely on Internet search engines to drive traffic to our website, and if we fail to appear high up in the search results, our traffic would decline and our business would be adversely affected.

We depend in part on Internet search engines, such as Google, Bing, and Yahoo!, to drive traffic to our website. For example, when a user types a physical address into a search engine, we rely on a high organic search ranking of our webpages in these search results to refer the user to our website. However, our ability to maintain high organic search result rankings is not within our control. Our competitors’ search engine optimization, or SEO, efforts may result in their websites receiving a higher search result page ranking than ours, or Internet search engines could revise their methodologies in a way that would adversely affect our search result rankings. If Internet search engines modify their search algorithms in ways that are detrimental to us, or if our competitors’ SEO efforts are more successful than ours, overall growth in our user base could slow. Search engine providers could provide listings and other real estate information directly in search results or choose to align with our competitors. Our website has experienced fluctuations in search result rankings in the past, and we anticipate similar fluctuations in the future. Any reduction in the number of users directed to our website through search engines could harm our business and operating results.

Our recent revenue growth rates may not be indicative of our future growth, and we may not continue to grow at our recent pace, or at all.

From 2007 to 2011, our revenue grew from $1.7 million to $38.5 million, which represents a compounded annual growth rate of approximately 119%. In the future, our revenue may not grow as rapidly as it has over the past several years. For instance, while our media revenue grew more rapidly in the year ended December 31, 2011 than the year ended December 31, 2010, our media revenue grew more slowly in the six months ended December 31, 2011 than it did in the six months ended June 30, 2011. We believe that our future revenue growth will depend, among other factors, on our ability to:

We may not be successful in our efforts to do any of the foregoing, and any failure to be successful in these matters could materially and adversely affect our revenue growth. You should not consider our past revenue growth to be indicative of our future growth.

Our revenue and operating results could vary significantly from period to period, which could cause the market price of our common stock to decline.

We generate revenue through sales of subscriptions to real estate professionals and sales of display advertising to advertisers. Our subscription and advertising sales can be difficult to predict and may result in fluctuations in our revenue from period to period. Our revenue and operating results have fluctuated in the past, and may continue to fluctuate in the future, as a result of a variety of factors, many of which are outside of our control. As a result, comparing our revenue and operating results on a period-to-period basis may not be meaningful, and you should not rely on past results as an indication of future performance.

Our revenue, operating results, or both, may be affected by a number of factors, including:

For example, individuals hired to join our sales team typically do not reach their maximum productivity until they have been employed for several months or more. Our fixed expenses related to the addition of personnel may not result in an increase in revenue in a given period or at all.

As a result of the foregoing factors and others discussed in this “Risk Factors” section, our operating results in one or more future periods may fail to meet or exceed our projections or the expectations of securities analysts or investors. In that event, the trading price of our common stock would likely decline.

Seasonality may cause fluctuations in our traffic, revenue, and operating results.

We generally experience seasonality in subscription revenue and display advertising due to fluctuations in traffic to our website and mobile applications. During the fourth quarter of each year, traffic to our marketplace has historically declined and our revenue has historically grown more slowly than in other quarters. Conversely, we typically experience higher growth in traffic and revenue during the spring and summer months, when consumers are more likely to buy new homes. We expect that seasonality will continue to affect traffic in our marketplace, as well as our revenue from subscriptions and advertising.

Declines in, or changes to, the real estate industry could adversely affect our business and financial performance.

Our business and financial performance are affected by the health of, and changes to, the residential real estate industry. Although we have built and grown our business during a worldwide economic downturn, home-buying patterns are sensitive to economic conditions and tend to decline or grow more slowly during these periods. A decrease in home purchases could lead to reductions in user traffic, reductions in subscriptions by real estate professionals, and a decline in marketing spend. Furthermore, online advertising products may be viewed by some existing and potential advertisers on our website and mobile applications as a lower priority, which could cause advertisers to reduce the amounts they spend on advertising, terminate their use of our products, or default on their payment obligations to us. In addition, we may become subject to rules and regulations in the real estate industry that may restrict or complicate our ability to deliver our products. These changes would harm our business and operating results.

Most recently, beginning in 2008, domestic and global economic conditions deteriorated rapidly, resulting in a dramatic slowdown in the housing market, which slowed advertising spending in the real estate industry. In addition, changes to the regulation of the real estate industry and related areas, including mortgage lending and the deductibility of home mortgage interest, may negatively affect the prevalence of home purchases. Real estate markets also may be negatively impacted by a significant natural disaster, such as earthquake, fire, flood, or other disruption. Declines or disruptions in the real estate market or increases in mortgage interest rates could reduce demand for our products and could harm our business and operating results.

We participate in a highly competitive market, and pressure from existing and new companies may adversely affect our business and operating results.

The market to provide home listings and marketing services for the residential real estate industry is highly competitive and fragmented. Homes are not typically marketed exclusively through any single channel. Consumers can access home listings and related data through more than one source. Accordingly, current and potential competitors could aggregate a set of listings similar to ours. We compete with online real estate marketplaces, such as Zillow and Realtor.com, other real estate websites, and traditional offline media. We compete to attract consumers primarily on the basis of the number and quality of listings; user experience; the breadth, depth, and relevance of insights and other content on homes, neighborhoods, and professionals; brand and reputation; and the quality of mobile products. We compete to attract real estate professionals primarily on the basis of the quality of the website and mobile products, the size and attractiveness of the consumer audience, the quality and measurability of the leads we generate, the perceived return on investment we deliver, and the effectiveness of marketing and workflow tools. We also compete for advertisers against other media, including print media, television and radio, social networks, search engines, other websites, and email marketing. We compete primarily on the basis of the size and attractiveness of the audience; pricing; and the ability to target desired audiences.

Many of our existing and potential competitors have substantial competitive advantages, such as:

The success of our competitors could result in fewer users visiting our website and mobile applications, the loss of subscribers and advertisers, price reductions for our subscriptions and display advertising, weaker operating results, and loss of market share. Our competitors also may be able to provide users with products that are different from or superior to those we can provide, or to provide users with a broader range of products and prices.

We expect increased competition if our market continues to expand. In addition, current or potential competitors may be acquired by third parties with greater resources than ours, which would further strengthen these current or potential competitors and enable them to compete more vigorously or broadly with us. If we are not able to compete effectively, our business and operating results will be materially and adversely affected.

If our users do not continue to contribute content or their contributions are not valuable to other users, our marketplace would be less attractive, which could negatively affect our unique visitor traffic and revenue.

Our success depends on our ability to provide consumers with the information they seek, which in turn depends in part on the content contributed by our users. We believe that one of our primary competitive advantages is the quality and quantity of the user-generated content in our marketplace, and that information is one of the main reasons consumers use our platform. If we are unable to provide consumers with the information they seek because our users do not contribute content, or because the content that they contribute is not helpful and reliable, the number of consumers visiting our website and mobile applications may decline. If we experience a decline in consumers visiting our website and using our mobile applications, real estate professionals and advertisers may not view our marketplace as attractive for their marketing expenditures, and may reduce their spending with us. Any decline in visits to our website and usage of mobile applications by consumers and any decline in spending by real estate professionals and advertisers with us would harm our business and operating results.

In addition, we monitor new contributions to user-generated content because we believe this metric is a key indicator of our user engagement and the strength of our community. In the event that the number of new contributions to user-generated content declines, this metric may provide a leading indicator of the health of our business. However, if the quantity of new contributions to user-generated content continues to increase but the quality of user-generated content declines, this metric would not capture any corresponding declines in user engagement or the strength of our community as evidenced by the lower quality of user-generated content, and such data would be of limited use in those circumstances.

Our growth depends in part on our relationship with third parties to provide us with local information.

Third parties provide us with information that we use to provide users with insights that go beyond listings, such as information about schools, crime, and neighborhood amenities. Property descriptions and sale transactions obtained via third-party data providers also inform the valuations provided by our Trulia Estimates feature. If these third-party data providers terminate their relationships with us, the information that we provide to users may be limited or the quality of the information may suffer. If we are unable to renew our agreements with these data providers on favorable terms to us or to secure alternative sources for this information, our costs may increase and our business may be harmed.

If we do not display accurate and complete information on a timely basis, our user traffic may decline, our reputation would suffer, and our business and operating results would be harmed.

We receive listing and other information provided by listing aggregators and other third parties that we include on our website and mobile applications. Our reputation with consumers depends on the accuracy and completeness of the information that we provide, although the accuracy and completeness of this data is often outside of our control. We cannot independently verify the accuracy or completeness of all of the information provided to us by third parties. If third parties provide us with inaccurate or incomplete information that we then display on our website and mobile applications, consumers may become dissatisfied with our products, our

traffic may decrease, and our reputation may suffer. Real estate professionals also expect listings data and other information to be accurate and complete, and to the extent our information is incorrect or incomplete, our reputation and business relationships may suffer.

In addition, we update the listing information that we provide on our website and mobile applications on a daily basis. To the extent that we are no longer able to update information in our marketplace on a timely basis, or if consumers begin to expect updates in a more timely manner, we may be forced to make investments which allow us to update information with higher frequency. There can be no assurance that we will be able to provide information at a pace necessary to satisfy consumers in a cost-effective manner, or at all.

Growth of our business will depend on a strong brand, and any failure to maintain, protect, and enhance our brand would hurt our ability to retain or expand our base of users, or our ability to increase their level of engagement.

We believe that a strong brand is necessary to continue to attract and retain consumers and, in turn, the real estate professionals and others who choose to advertise on our websites and mobile applications. We need to maintain, protect, and enhance the “Trulia” brand in order to expand our base of users and increase their engagement with our website and mobile applications. This will depend largely on our ability to continue to provide high-value, differentiated products, and we may not be able to do so effectively. While we may choose to engage in a broader marketing campaign to further promote our brand, this effort may not be successful. Furthermore, negative publicity about our company, including our content, technology, sales practices, personnel, or customer service could diminish confidence in and the use of our products, which could harm our operating results. If we are unable to maintain or enhance user and advertiser awareness of our brand cost effectively, our business, operating results, and financial condition could be harmed. In addition, our website serves as a forum for expression by our users, and if some of our users contribute inappropriate content and offend other users, our reputation could be harmed.

We rely on a small number of advertising partners for a substantial portion of our media revenue, and we are subject to risks as a result of this advertiser concentration.

In each of the years ended December 31, 2010 and 2011, the ten largest advertising partners for the respective period accounted for more than 50% of our media revenue. For the six months ended June 30, 2012, the ten largest advertising partners in that period accounted for more than 60% of our media revenue. One of our growth strategies is to increase the amount large advertisers spend in our marketplace, and we expect this revenue concentration to continue. If one or more of these large advertisers were to decrease or discontinue advertising with us, our business and operating results will be adversely affected.

Our operating results may be adversely affected by a failure to collect amounts owed to us by advertisers.

We often run display advertisements in our marketplace prior to receiving payment from an advertiser, which makes us subject to credit risks. In the past, certain advertisers have been unable to pay us due to bankruptcy or other reasons, and we cannot assure you that we will not experience collection issues in the future. If we have difficulty collecting amounts owed to us by advertisers, or fail to collect these amounts at all, our results of operations and financial condition would be adversely affected.

We depend on our talented personnel to grow and operate our business, and if we are unable to hire, retain, manage, and motivate our personnel, or if our new personnel do not perform as we anticipate, we may not be able to grow effectively.

Our future success will depend upon our continued ability to identify, hire, develop, motivate, and retain talented personnel. We may not be able to retain the services of any of our employees or other members of senior management in the future. We do not have employment agreements other than offer letters with any key employee,

and we do not maintain key person life insurance for any employee. In addition, from time to time, there may be changes in our senior management team that may be disruptive to our business. If our senior management team fails to work together effectively and to execute our plans and strategies, our business could be harmed.

Our growth strategy also depends on our ability to expand our organization by hiring high-quality personnel. Identifying, recruiting, training, integrating, managing, and motivating talented individuals will require significant time, expense, and attention. Competition for talent is intense, particularly in the San Francisco Bay Area, where our headquarters is located. If we are not able to effectively recruit and retain our talent, our business and our ability to achieve our strategic objectives would be harmed.

Growth may place significant demands on our management and our infrastructure.

We have experienced substantial growth in our business that has placed, and may continue to place, significant demands on our management and our operational and financial infrastructure. As our operations grow in size, scope, and complexity, we will need to improve and upgrade our systems and infrastructure. The expansion of our systems and infrastructure will require us to commit substantial financial, operational, and technical resources in advance of an increase in the volume of business, with no assurance that the volume of business will increase. Continued growth could also strain our ability to maintain reliable service levels for our users and advertisers, develop and improve our operational, financial, and management controls, enhance our reporting systems and procedures, and recruit, train, and retain highly skilled personnel.

Our products are accessed by a large number of users often at the same time. If the use of our marketplace continues to expand, we may not be able to scale our technology to accommodate increased capacity requirements, which may result in interruptions or delays in service. The failure of our systems and operations to meet our capacity requirements could result in interruptions or delays in service or impede our ability to scale our operations.

Managing our growth will require significant expenditures and allocation of valuable management resources. If we fail to achieve the necessary level of efficiency in our organization as it grows, our business, operating results, and financial condition would be harmed.

A significant disruption in service on our website or of our mobile applications could damage our reputation and result in a loss of users of our products and of advertisers, which could harm our business, operating results, and financial condition.

Our brand, reputation, and ability to attract users and advertisers depend on the reliable performance of our network infrastructure and content delivery. We may experience significant interruptions with our systems in the future. Interruptions in these systems, whether due to system failures, computer viruses, or physical or electronic break-ins, could affect the security or availability of our products on our website and mobile applications, and prevent or inhibit the ability of users to access our products. Problems with the reliability or security of our systems could harm our reputation, result in a loss of users of our products and of advertisers, and result in additional costs.

Substantially all of the communications, network, and computer hardware used to operate our website and mobile applications is located at a single colocation facility in Santa Clara, California. While we have made investments to back up our system in the event of a disruption involving this facility, our systems are not fully redundant. In addition, we do not own or control the operation of this facility. Our systems and operations are vulnerable to damage or interruption from fire, flood, power loss, telecommunications failure, terrorist attacks, acts of war, electronic and physical break-ins, computer viruses, earthquakes, and similar events. The occurrence of any of these events could result in damage to our systems and hardware or could cause them to fail.

Problems faced by our third-party web hosting providers could adversely affect the experience of our users. Our third-party web hosting providers could close their facilities without adequate notice. Any financial difficulties, up to and including bankruptcy, faced by our third-party web hosting providers or any of the service

providers with whom they contract may have negative effects on our business, the nature and extent of which are difficult to predict. If our third-party web hosting providers are unable to keep up with our growing capacity needs, our business could be harmed.

Any errors, defects, disruptions, or other performance or reliability problems with our network operations could cause interruptions in access to our products as well as delays and additional expense in arranging new facilities and services and could harm our reputation, business, operating results, and financial condition.

Our failure to protect confidential information of our users against security breaches could damage our reputation and brand and harm our business and operating results.

We maintain sensitive information provided by users and advertisers. We rely on encryption and authentication technology licensed from third parties to effect secure transmission of confidential information, including personally identifiable information and credit card numbers. We may need to expend significant resources to protect against security breaches or to address problems caused by breaches. If we are unable to maintain the security of confidential information that is provided to us by our users, our reputation and brand could be harmed and we may be exposed to a risk of loss or litigation and possible liability, any of which could harm our business and operating results.

Failure to adequately protect our intellectual property could harm our business and operating results.

Our business depends on our intellectual property, the protection of which is crucial to the success of our business. We rely on a combination of patent, trademark, trade secret, and copyright law and contractual restrictions to protect our intellectual property. In addition, we attempt to protect our intellectual property, technology, and confidential information by requiring our employees and consultants to enter into confidentiality and assignment of inventions agreements and third parties to enter into nondisclosure agreements. These agreements may not effectively prevent unauthorized use or disclosure of our confidential information, intellectual property, or technology and may not provide an adequate remedy in the event of unauthorized use or disclosure of our confidential information, intellectual property, or technology. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our website features, software, and functionality or obtain and use information that we consider proprietary.

We have registered “Trulia” as a trademark in the United States, the European Union and Canada. Competitors may adopt service names similar to ours, thereby harming our ability to build brand identity and possibly leading to user confusion. In addition, there could be potential trade name or trademark infringement claims brought by owners of other registered trademarks or trademarks that incorporate variations of the term “Trulia.”

We currently hold the “Trulia.com” Internet domain name and various other related domain names. The regulation of domain names in the United States is subject to change. Regulatory bodies could establish additional top-level domains, appoint additional domain name registrars, or modify the requirements for holding domain names. As a result, we may not be able to acquire or maintain all domain names that use the name Trulia.

Litigation or proceedings before the U.S. Patent and Trademark Office or other governmental authorities and administrative bodies in the United States and abroad may be necessary in the future to enforce our intellectual property rights, to protect our patent rights, trade secrets, and domain names and to determine the validity and scope of the proprietary rights of others. Our efforts to enforce or protect our proprietary rights may be ineffective and could result in substantial costs and diversion of resources, which could harm our business and operating results.

Intellectual property infringement assertions by third parties could result in significant costs and harm our business and operating results.

Other parties have asserted, and may in the future assert, that we have infringed their intellectual property rights. Such litigation may involve patent holding companies or other adverse patent owners who have no relevant product revenue, and therefore our own issued and pending patents may provide little or no deterrence.

We could also be required to pay damages in an unspecified amount. For example, in September 2011, we entered into a settlement agreement with CIVIX-DDI LLC, or CIVIX, relating to a claim by CIVIX that we infringed two CIVIX patents relating to searching and locating real estate. Under the settlement agreement, we agreed to pay CIVIX to settle the litigation.

Furthermore, we cannot predict whether assertions of third-party intellectual property rights or claims arising from such assertions will substantially harm our business and operating results. The defense of these claims and any future infringement claims, whether they are with or without merit or are determined in our favor, may result in costly litigation and diversion of technical and management personnel. Furthermore, an adverse outcome of a dispute may require us to pay damages, potentially including treble damages and attorneys’ fees, if we are found to have willfully infringed a party’s patent or copyright rights; cease making, licensing or using products that are alleged to incorporate the intellectual property of others; expend additional development resources to redesign our products; and enter into potentially unfavorable royalty or license agreements in order to obtain the right to use necessary technologies. Royalty or licensing agreements, if required, may be unavailable on terms acceptable to us, or at all. In any event, we may need to license intellectual property which would require us to pay royalties or make one-time payments. Even if these matters do not result in litigation or are resolved in our favor or without significant cash settlements, the time and resources necessary to resolve them could harm our business, operating results, financial condition, and reputation.

We provide data that is relevant to the decision to purchase a home and some of this data is subject to revision, interpretation, or dispute. For example, our Trulia Estimate tool provides users with home valuations and is based on algorithms we have developed to analyze third-party data. We revise our algorithms regularly, which may cause valuations to differ from those previously provided. Consumers and real estate professionals sometimes disagree with our estimates. Any such variation in or disagreements about the estimates that we present could result in negative user feedback, harm our reputation, or lead to legal disputes.

We accept payments using a variety of methods, including credit and debit cards. For certain payment methods, including credit and debit cards, we pay bank interchange and other fees, which may increase over time and raise our operating costs and lower profitability. We rely on third parties to provide payment processing services, including the processing of credit and debit cards and our business would be disrupted if these companies become unwilling or unable to provide these services to us. We are also subject to payment card association operating rules, certification requirements, and rules governing electronic funds transfers, which could change or be reinterpreted to make it difficult or impossible for us to comply. If we fail to comply with these rules or requirements, we may be subject to fines and higher transaction fees and lose our ability to accept credit and debit card payments from consumers or facilitate other types of online payments, and our business and operating results could be adversely affected.

Our business is subject to a variety of state and federal laws, many of which are unsettled and still developing and which could subject us to claims or otherwise harm our business.

We are subject to a variety of federal and state laws, including laws regarding data retention, privacy, and consumer protection, that are continuously evolving and developing. The scope and interpretation of the laws that are or may be applicable to us are often uncertain and may be conflicting. For example, laws relating to the liability of providers of online services for activities of their users and other third parties are currently being tested by a number of claims, including actions based on invasion of privacy and other torts, unfair competition, copyright and trademark infringement, and other theories based on the nature and content of the materials searched, the ads posted, or the content provided by users. In addition, regulatory authorities are considering a number of legislative and regulatory proposals concerning data protection and other matters that may be

applicable to our business. Changes to existing laws or regulations or the adoption of new laws or regulations could negatively affect our business. It is difficult to predict how existing laws will be applied to our business and the new laws to which we may become subject.

Our business may be adversely affected if we encounter difficulties as we implement an enterprise resource planning system.

We are in the process of implementing an enterprise resource planning, or ERP, systems for our company. This ERP system will combine and streamline the management of our financial, accounting, human resources, sales and marketing and other functions, enabling us to more effectively manage operations and track performance. However, this ERP system will require us to complete numerous processes and procedures for the effective use of this system or with running our business using this system, which may result in substantial costs. Until we have completed the implementation of an ERP system and have experience with its operation, the implementation of the new ERP system poses a risk to our disclosure controls, internal control over financial reporting, and business operations. Any disruptions or difficulties in implementing this system could adversely affect our controls and harm our business, including our ability to forecast or make sales and collect our receivables. Moreover, such disruption or difficulties could result in unanticipated costs or expenditures and diversion of management’s attention and resources.

If we fail to remediate deficiencies in our internal control over financial reporting or are unable to implement and maintain effective internal control over financial reporting in the future, the accuracy, and timeliness of our financial reporting may be adversely affected.

In connection with the audits of our financial statements for 2009, 2010, and 2011, we identified a material weakness in the design and operating effectiveness of our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, that creates a reasonable possibility that a material misstatement of a company’s annual or interim financial statements will not be prevented or detected on a timely basis.

The material weakness that we identified resulted from a lack of sufficient number of qualified personnel within our accounting function that possessed an appropriate level of expertise to effectively perform the following functions:

We are taking numerous steps that we believe will address the underlying causes of the control deficiencies described above, primarily through the hiring of additional accounting and finance personnel with technical accounting and financial reporting experience, development and implementation of policies, and improved processes and documented procedures. If we fail to effectively remediate deficiencies in our control environment or are unable to implement and maintain effective internal control over financial reporting to meet the demands that will be placed upon us as a public company, including the requirements of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, we may be unable to accurately report our financial results, or report them within the timeframes required by law or exchange regulations.

Even if we are able to report our financial statements accurately and in a timely manner, if we do not make all necessary improvements to address the material weakness, continued disclosure of a material weakness will be required in future filings with the Securities and Exchange Commission, or SEC, which could cause our reputation to be harmed and our stock price to decline.

We have not performed an evaluation of our internal control over financial reporting, such as required by Section 404 of the Sarbanes-Oxley Act, nor have we engaged our independent registered public accounting firm

to perform an audit of our internal control over financial reporting as of any balance sheet date or for any period reported in our financial statements. Had we performed such an evaluation or had our independent registered public accounting firm performed an audit of our internal control over financial reporting, control deficiencies, including material weaknesses and significant deficiencies, in addition to those discussed above, may have been identified. In addition, we are an “emerging growth company” as defined in the Jumpstart Our Business Startups Act, and as such we may elect to avail ourselves of the exemption from the requirement that our independent registered public accounting firm audit our internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act until we cease to be an “emerging growth company.” See “—We are an “emerging growth company,” and any decision on our part to comply only with certain reduced reporting and disclosure requirements applicable to emerging growth companies could make our common stock less attractive to investors,” for additional risks relating to our “emerging growth company” status.

Complying with the laws and regulations affecting public companies will increase our costs and the demands on management and could harm our operating results.

As a public company and particularly after we cease to be an “emerging growth company,” we will incur significant legal, accounting, and other expenses that we did not incur as a private company. In addition, the Sarbanes-Oxley Act and rules subsequently implemented by the SEC and the New York Stock Exchange impose various requirements on public companies, including requiring changes in corporate governance practices. Our management and other personnel will need to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations have increased and will continue to increase our legal, accounting, and financial compliance costs and have made and will continue to make some activities more time-consuming and costly. For example, we expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or to incur substantial costs to maintain the same or similar coverage. These rules and regulations could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors or our board committees or as executive officers.

In addition, the Sarbanes-Oxley Act requires, among other things, that we assess the effectiveness of our internal control over financial reporting annually and the effectiveness of our disclosure controls and procedures quarterly. In particular, beginning with the year ending December 31, 2013, we will need to perform system and process evaluation and testing of our internal control over financial reporting to allow management to report on, and our independent registered public accounting firm potentially to attest to, the effectiveness of our internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act, or Section 404. As an “emerging growth company” we may elect to avail ourselves of the exemption from the requirement that our independent registered public accounting firm attest to the effectiveness of our internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act. However, we may no longer avail ourselves of this exemption when we cease to be an “emerging growth company” and, when our independent registered public accounting firm is required to undertake an assessment of our internal control over financial reporting, the cost of our compliance with Section 404 will correspondingly increase. Our compliance with applicable provisions of Section 404 will require that we incur substantial accounting expense and expend significant management time on compliance-related issues as we implement additional corporate governance practices and comply with reporting requirements. Moreover, if we are not able to comply with the requirements of Section 404 applicable to us in a timely manner, or if we or our independent registered public accounting firm identifies deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, the market price of our stock could decline and we could be subject to sanctions or investigations by the SEC or other regulatory authorities, which would require additional financial and management resources.

Furthermore, investor perceptions of our company may suffer if deficiencies are found, and this could cause a decline in the market price of our stock. Irrespective of compliance with Section 404, any failure of our internal control over financial reporting could have a material adverse effect on our stated operating results and harm our

reputation. If we are unable to implement these changes effectively or efficiently, it could harm our operations, financial reporting, or financial results and could result in an adverse opinion on internal control from our independent registered public accounting firm.

We are an “emerging growth company,” and any decision on our part to comply only with certain reduced reporting and disclosure requirements applicable to emerging growth companies could make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act enacted in April 2012, and, for as long as we continue to be an “emerging growth company,” we may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to “emerging growth companies,” including, but not limited to, not being required to have our independent registered public accounting firm audit our internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We could be an “emerging growth company” for up to five years following the completion of this offering, although, if we have more than $1.0 billion in annual revenue, if the market value of our common stock that is held by non-affiliates exceeds $700 million as of June 30 of any year, or we issue more than $1.0 billion of non-convertible debt over a three-year period before the end of that five-year period, we would cease to be an “emerging growth company” as of the following December 31. We cannot predict if investors will find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as a result of any choices to reduce future disclosure, there may be a less active trading market for our common stock and our stock price may be more volatile.

Under the Jumpstart Our Business Startups Act, emerging growth companies can delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards, and, therefore, we will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

On September 15, 2011, we entered into a loan and security agreement with Hercules Technology Growth Capital, Inc., or Hercules, providing for a secured term loan facility, or the credit facility, in an aggregate principal amount of up to $20.0 million to be used for general business purposes. Indebtedness we incur under this agreement is secured by substantially all of our assets. This agreement contains customary affirmative and negative covenants, including covenants that limit or restrict our ability to, among other things, incur additional indebtedness, grant liens, make investments, repurchase stock, pay dividends, transfer assets, merge or consolidate, and make acquisitions. In May 2012, we failed to comply with the covenant that required delivery of audited financial statements for the year ended December 31, 2011 within the time period set forth in the credit facility. Hercules granted a waiver arising from our failure to comply with this reporting covenant. If we default on our obligations under this agreement, Hercules may foreclose on our assets to repay our outstanding obligations to Hercules, which would materially and adversely impact our business. As of June 30, 2012, we had drawn $10.0 million in term loans under the credit facility, and an additional $10.0 million in term loans remained available to be drawn, subject to the terms and conditions of the credit facility. If we default on payments due pursuant to the credit facility and are forced to sell assets to satisfy these obligations, our business would be materially and adversely affected.

Our operating results may be harmed if we are required to collect sales taxes for our products.

There is general uncertainty in the industry about the obligation of Internet-based businesses to collect and remit sales taxes in jurisdictions where their commerce is solely virtual. In the current climate, it is possible that one or more states or countries could seek to impose sales or other tax collection obligations on us or our subscribers

with regards to our products, which taxes may be applicable to past sales. A successful assertion that we should be collecting additional sales or other taxes on our products could result in substantial tax liabilities for past sales, discourage subscribers from purchasing our products, or otherwise harm our business and operating results.

If we fail to expand effectively into adjacent markets, our growth prospects could be harmed.

We intend to expand our operations into adjacent markets, such as rentals, mortgages, and home improvement, and into international geographies. We may incur losses or otherwise fail to enter these markets successfully. Our expansion into these markets will place us in competitive environments with which we are unfamiliar and involves various risks, including the need to invest significant resources and the possibility that returns on such investments will not be achieved for several years, or at all. In attempting to establish a presence in new markets, we expect to incur significant expenses and face various other challenges, such as expanding our sales force and management personnel to cover these markets.

Future acquisitions and investments could disrupt our business and harm our financial condition and operating results.

Our success will depend, in part, on our ability to expand our products and markets, and grow our business in response to changing technologies, user, and advertiser demands, and competitive pressures. In some circumstances, we may determine to do so through the acquisition of complementary businesses and technologies rather than through internal development, including, for example, our recent acquisition of Movity, Inc., a geographic data company. The identification of suitable acquisition candidates can be difficult, time-consuming, and costly, and we may not be able to successfully complete identified acquisitions. The risks we face in connection with acquisitions include:

Our failure to address these risks or other problems encountered in connection with our past or future acquisitions and investments could cause us to fail to realize the anticipated benefits of these acquisitions or investments, cause us to incur unanticipated liabilities, and harm our business generally. Future acquisitions could also result in dilutive issuances of our equity securities, the incurrence of debt, contingent liabilities, amortization expenses, or the write-off of goodwill, any of which could harm our financial condition. Also, the anticipated benefits of any acquisitions may not materialize.

We may require additional capital to support business growth, and this capital might not be available on acceptable terms, if at all.

We intend to continue to make investments to support our business growth and may require additional funds to respond to business challenges, including the need to develop new features and products or enhance our existing products, improve our operating infrastructure, or acquire complementary businesses and technologies. Accordingly, we may need to engage in equity or debt financings to secure additional funds. If we raise additional funds through future issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences, and privileges superior to those of holders of our common stock. Any debt financing we secure in the future could involve restrictive covenants relating to our capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. We may not be able to obtain additional financing on terms favorable to us, if at all. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to support our business growth and to respond to business challenges could be impaired, and our business may be harmed.

Concentration of ownership among our existing executive officers, directors, and their affiliates may prevent new investors from influencing significant corporate decisions.

Upon completion of this offering, our executive officers, directors, and holders of 5% or more of our outstanding common stock will beneficially own, in the aggregate, approximately 61.1% of our outstanding shares of common stock. Some of these persons or entities may have interests that are different from yours. For example, these stockholders may support proposals and actions with which you may disagree or which are not in your interests. These stockholders will be able to exercise a significant level of control over all matters requiring stockholder approval, including the election of directors, amendment of our certificate of incorporation, and approval of significant corporate transactions. This control could have the effect of delaying or preventing a change of control of our company or changes in management and will make the approval of certain transactions difficult or impossible without the support of these stockholders, which in turn could reduce the price of our common stock.

An active, liquid, and orderly trading market for our common stock may not develop, the price of our stock may be volatile, and you could lose all or part of your investment.

Prior to this offering, there has been no public market for shares of our common stock. The initial public offering price of our common stock will be determined through negotiation with the underwriters. This price will not necessarily reflect the price at which investors in the market will be willing to buy and sell our shares of common stock following this offering. In addition, the trading price of our common stock following this offering is likely to be highly volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control.

In addition, the stock market in general, and the market for technology companies in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. Broad market and industry factors may seriously affect the market price of companies’ stock, including ours, regardless of actual operating performance. These fluctuations may be even more pronounced in the trading market for our stock shortly following this offering. In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’s attention and resources.

The price of our common stock may be volatile, and you could lose all or part of your investment.

The trading price of our common stock following this offering may fluctuate substantially and may be higher or lower than the initial public offering price. The trading price of our common stock following this

offering will depend on a number of factors, including those described in this “Risk Factors” section, many of which are beyond our control and may not be related to our operating performance. These fluctuations could cause you to lose all or part of your investment in our common stock since you might be unable to sell your shares at or above the price you paid in this offering. Factors that could cause fluctuations in the trading price of our common stock include the following:

In addition, the stock market in general, and the market for technology companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. Broad market and industry factors may seriously affect the market price of our common stock, regardless of our actual operating performance. In addition, in the past, following periods of volatility in the overall market and the market prices of a particular companies’ securities, securities class action litigations have often been instituted against these companies. Litigation of this type, if instituted against us, could result in substantial costs and a diversion of our management’s attention and resources.

A total of 20,376,654, or 77.3%, of our total outstanding shares after the offering are restricted from immediate resale, but may be sold on a stock exchange in the near future. The large number of shares eligible for public sale or subject to rights requiring us to register them for public sale could depress the market price of our common stock.

The market price of our common stock could decline as a result of sales of a large number of shares of our common stock in the market after this offering, and the perception that these sales could occur may also depress the

market price of our common stock. Based on shares outstanding as of June 30, 2012, after giving effect to the issuance of 89,100 shares of our common stock to be acquired by certain stockholders through option exercises at the closing of this offering in order to sell those shares in this offering, we will have 26,376,654 shares of common stock outstanding after this offering. Of these shares, the common stock sold in this offering will be freely tradable in the United States, except for any shares purchased by our “affiliates” as defined in Rule 144 under the Securities Act of 1933. The holders of shares of outstanding common stock have agreed with the underwriters, subject to certain exceptions, not to dispose of or hedge any of their common stock during the 180-day period beginning on the date of this prospectus, except with the prior written consent of J.P. Morgan Securities LLC and Deutsche Bank Securities Inc. After the expiration of the 180-day restricted period, these shares may be sold in the public market in the United States, subject to prior registration in the United States, if required, or reliance upon an exemption from United States registration, including, in the case of shares held by affiliates or control persons, compliance with the volume restrictions of Rule 144. In addition, a portion of these shares is subject to early release under certain circumstances described in the section titled “Underwriting” in this prospectus.

Upon completion of this offering, stockholders owning an aggregate of 20,376,654 shares will be entitled, under contracts providing for registration rights, to require us to register shares of our common stock owned by them for public sale in the United States. In addition, we intend to file a registration statement to register the approximately 6,112,904 shares reserved for future issuance under our equity compensation plans. Upon effectiveness of that registration statement, subject to the satisfaction of applicable exercise periods and, in certain cases, lock-up agreements with the representatives of the underwriters referred to above, the shares of common stock issued upon exercise of outstanding options will be available for immediate resale in the United States in the open market.

Sales of our common stock as restrictions end or pursuant to registration rights may make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. These sales also could cause our stock price to fall and make it more difficult for you to sell shares of our common stock.

Anti-takeover provisions contained in our certificate of incorporation and bylaws, as well as provisions of Delaware law, could impair a takeover attempt.

Our certificate of incorporation, bylaws, and Delaware law contain or will contain provisions which could have the effect of rendering more difficult, delaying, or preventing an acquisition deemed undesirable by our board of directors. Our corporate governance documents include or will include provisions:

These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in our management.

As a Delaware corporation, we are also subject to provisions of Delaware law, including Section 203 of the Delaware General Corporation law, which prevents some stockholders holding more than 15% of our outstanding common stock from engaging in certain business combinations without approval of the holders of substantially all of our outstanding common stock.

Any provision of our certificate of incorporation, bylaws or Delaware law that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock, and could also affect the price that some investors are willing to pay for our common stock.

We may invest or spend the proceeds of this offering in ways with which you may not agree or in ways which may not yield a return.

The net proceeds from the sale of our shares of common stock by us in this offering may be used for general corporate purposes, including working capital. We may also use a portion of the net proceeds to acquire complementary businesses, products, services, or technologies. However, we do not have any agreements or commitments for any acquisitions at this time. Our management will have considerable discretion in the application of the net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. The net proceeds may be invested with a view towards long-term benefits for our stockholders and this may not increase our operating results or market value. Until the net proceeds are used, they may be placed in investments that do not produce significant income or that may lose value.

Purchasers in this offering will experience immediate and substantial dilution in the book value of their investment.

The anticipated initial public offering price of our common stock of $15.00, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, is substantially higher than the net tangible book value per share of our outstanding common stock immediately after this offering. Therefore, if you purchase our common stock in this offering, you will incur immediate dilution of $12.68 in the net tangible book value per share from the price you paid. In addition, following this offering, purchasers in the offering will have contributed 64.7% of the total consideration paid by our stockholders to purchase shares of common stock, in exchange for acquiring approximately 19.0% of our total outstanding shares as of June 30, 2012 after giving effect to this offering. The exercise of outstanding stock options will result in further dilution.

If securities or industry analysts do not publish or cease publishing research or reports about us, our business or our market, or if they change their recommendations regarding our stock adversely, our stock price and trading volume could decline.

The trading market for our common stock will be influenced by the research and reports that industry or securities analysts may publish about us, our business, our market, or our competitors. If any of the analysts who may cover us change their recommendation regarding our stock adversely, or provide more favorable relative recommendations about our competitors, our stock price would likely decline. If any analyst who may cover us were to cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline.

We do not anticipate declaring any cash dividends to holders of our common stock in the foreseeable future. In addition, the terms of our credit facility currently prohibit us from paying cash dividends on our capital stock. Consequently, investors may need to rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investment. Investors seeking cash dividends should not purchase our common stock.

This prospectus contains forward-looking statements within the meaning of the federal securities laws, which statements involve substantial risks and uncertainties. Forward-looking statements generally relate to future events or our future financial or operating performance. In some cases, you can identify forward-looking statements because they contain words such as “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “could,” “intends,” “target,” “projects,” “contemplates,” “believes,” “estimates,” “predicts,” “potential” or “continue” or the negative of these words or other similar terms or expressions that concern our expectations, strategy, plans or intentions. Forward-looking statements contained in this prospectus include, but are not limited to, statements about:

We caution you that the foregoing list may not contain all of the forward-looking statements made in this prospectus.

You should not rely upon forward-looking statements as predictions of future events. We have based the forward-looking statements contained in this prospectus primarily on our current expectations and projections about future events and trends that we believe may affect our business, financial condition, results of operations, and prospects. The outcome of the events described in these forward-looking statements is subject to risks, uncertainties, and other factors described in the section titled “Risk Factors” and elsewhere in this prospectus. Moreover, we operate in a very competitive and rapidly changing environment.

The forward-looking statements made in this prospectus relate only to events as of the date on which the statements are made. We undertake no obligation to update any forward-looking statements made in this prospectus to reflect events or circumstances after the date of this prospectus or to reflect new information or the occurrence of unanticipated events, except as required by law.

This prospectus also contains statistical data, estimates, and forecasts that are based on independent industry publications, such as those published by Borrell Associates, the National Association of Realtors, and the Real Estate Book, or other publicly available information, as well as other information based on our internal sources. Although we believe that the third-party sources referred to in this prospectus are reliable, neither we nor the underwriters have independently verified the information provided by these third parties. While we are not aware of any misstatements regarding any third-party information presented in this prospectus, their estimates, in particular, as they relate to projections, involve numerous assumptions, are subject to risks and uncertainties, and are subject to change based on various factors, including those discussed under the section titled “Risk Factors” and elsewhere in this prospectus.

We estimate that the net proceeds from the sale of shares of our common stock that we are selling in this offering will be approximately $65.8 million, based upon an assumed initial public offering price of $15.00 per share, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. If the underwriters’ option to purchase additional shares from us is exercised in full, we estimate that our net proceeds would be approximately $78.3 million, after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. We will not receive any proceeds from the sale of shares of our common stock by the selling stockholders.

Each $1.00 increase or decrease in the assumed initial public offering price of $15.00 per share would increase or decrease the net proceeds that we receive from this offering by approximately $4.7 million, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting the estimated underwriting discounts and commissions payable by us. Similarly, each increase or decrease of one million in the number of shares of common stock offered by us would increase or decrease the net proceeds that we receive from this offering by approximately $14.0 million, assuming the assumed initial public offering price remains the same and after deducting the estimated underwriting discounts and commissions payable by us.

The principal purposes of this offering are to increase our financial flexibility, create a public market for our common stock, and facilitate our future access to the public equity markets.

We currently intend to use the net proceeds that we will receive from this offering for working capital and other general corporate purposes. We may also use a portion of the net proceeds that we receive to acquire or invest in complementary businesses, products, services, technologies, or other assets. We have not entered into any agreements or commitments with respect to any acquisitions or investments at this time.

We cannot specify with certainty the particular uses of the net proceeds that we will receive from this offering. Accordingly, we will have broad discretion in using these proceeds. Pending the use of proceeds from this offering as described above, we plan to invest the net proceeds that we receive in this offering in short-term and intermediate-term interest-bearing obligations, investment-grade investments, certificates of deposit, or direct or guaranteed obligations of the U.S. government.

We have never declared or paid any cash dividend on our capital stock. We currently intend to retain any future earnings and do not expect to pay any dividends in the foreseeable future. Any future determination to declare cash dividends will be made at the discretion of our board of directors, subject to applicable laws, and will depend on a number of factors, including our financial condition, results of operations, capital requirements, contractual restrictions, general business conditions, and other factors that our board of directors may deem relevant. In addition, the terms of our credit facility currently prohibit us from paying cash dividends on our capital stock.

The following table sets forth cash and cash equivalents and short-term investments, as well as our capitalization, as of June 30, 2012 as follows:

The pro forma as adjusted information set forth in the table below is illustrative only and will be adjusted based on the actual initial public offering price and other final terms of this offering. You should read this table together with our financial statements and related notes, and the sections titled “Selected Financial and Other Data” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” that are included elsewhere in this prospectus.

If the underwriters’ option to purchase additional shares from us were exercised in full, pro forma as adjusted cash and cash equivalents and short-term investments, additional paid-in capital, total stockholders’ equity (deficit) and shares outstanding as of June 30, 2012 would be $88.9 million, $119.8 million, $75.9 million and 27,276,654, respectively.

The pro forma and pro forma as adjusted columns in the table above exclude the following:

If you invest in our common stock in this offering, your ownership interest will be diluted to the extent of the difference between the initial public offering price per share of our common stock and the pro forma as adjusted net tangible book value per share of our common stock immediately after this offering. Net tangible book value dilution per share to new investors represents the difference between the amount per share paid by purchasers of shares of common stock in this offering and the pro forma as adjusted net tangible book value per share of common stock immediately after completion of this offering.

Net tangible book value per share is determined by dividing our total tangible assets less our total liabilities by the number of shares of common stock outstanding. Our historical net tangible book value (deficit) as of June 30, 2012 was $(5.4) million, or $(0.76) per share. Our pro forma net tangible book value (deficit) as of June 30, 2012 was $(4.8) million, or $(0.22) per share, based on the total number of shares of our common stock outstanding as of June 30, 2012, after giving effect to the automatic conversion of all outstanding shares of our convertible preferred stock as of June 30, 2012 into an aggregate of 14,161,444 shares of common stock, which conversion will occur immediately prior to the completion of this offering, and the resulting reclassification of the preferred stock warrant liability to additional paid-in capital.

After giving effect to the sale by us of 5,000,000 shares of common stock in this offering at the assumed initial public offering price of $15.00 per share, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, as well as the issuance of 89,100 shares of our common stock to be acquired by certain selling stockholders through option exercises at the closing of this offering in order to sell those shares in this offering, our pro forma as adjusted net tangible book value as of June 30, 2012 would have been $61.2 million, or $2.32 per share. This represents an immediate increase in pro forma net tangible book value of $2.54 per share to our existing stockholders and an immediate dilution in pro forma net tangible book value of $12.68 per share to investors purchasing shares of common stock in this offering at the assumed initial public offering price. The following table illustrates this dilution:

Each $1.00 increase or decrease in the assumed initial public offering price of $15.00 per share, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, would increase or decrease, as applicable, our pro forma as adjusted net tangible book value per share to new investors by $0.18, and would increase or decrease, as applicable, dilution per share to new investors in this offering by $0.82, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting estimated underwriting discounts and commissions payable by us. In addition, to the extent any outstanding options or warrants to purchase common stock or convertible preferred stock are exercised, new investors would experience further dilution. If the underwriters exercise their option to purchase additional shares from us in full, the pro forma as adjusted net tangible book value per share of our common stock immediately after this offering would be $2.71 per share, and the dilution in pro forma net tangible book value per share to new investors in this offering would be $12.29 per share.

The following table presents, on a pro forma as adjusted basis as of June 30, 2012, after giving effect to the conversion of all outstanding shares of convertible preferred stock into common stock immediately prior to the completion of this offering, the differences between the existing stockholders and the new investors purchasing shares of our common stock in this offering with respect to the number of shares purchased from us, the total

consideration paid or to be paid to us, which includes net proceeds received from the issuance of common stock and convertible preferred stock, cash received from the exercise of stock options, and the average price per share paid or to be paid to us at an assumed offering price of $15.00 per share, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, before deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us:

Each $1.00 increase or decrease in the assumed initial public offering price of $15.00 per share, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, would increase or decrease, as applicable, the total consideration paid by new investors and total consideration paid by all stockholders by approximately $4.7 million, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting estimated underwriting discounts and commissions payable by us. In addition, to the extent any outstanding options or warrants to purchase common stock or convertible preferred stock are exercised, new investors will experience further dilution.

Except as otherwise indicated, the above discussion and tables assume no exercise of the underwriters’ option to purchase additional shares. If the underwriters exercise their option to purchase additional shares in full from us, our existing stockholders would own 78.4% and our new investors would own 21.6% of the total number of shares of our common stock outstanding upon the completion of this offering.

The number of shares of our common stock to be outstanding after this offering is based on the number of shares of our common stock outstanding as of June 30, 2012, and after giving effect to the issuance of 89,100 shares of our common stock to be acquired by certain selling stockholders through option exercises at the closing of this offering in order to sell those shares in this offering, and excludes:

Adjusted EBITDA is a financial measure that is not calculated in accordance with generally accepted accounting principles in the United States, or GAAP. We define Adjusted EBITDA as net loss adjusted to exclude interest income, interest expense, depreciation and amortization, change in the fair value of our warrant liability and stock-based compensation. Below, we have provided a reconciliation of Adjusted EBITDA to our net loss, the most directly comparable financial measure calculated and presented in accordance with GAAP. Adjusted EBITDA should not be considered as an alternative to net loss or any other measure of financial performance calculated and presented in accordance with GAAP. Our Adjusted EBITDA may not be comparable to similarly titled measures of other organizations because other organizations may not calculate Adjusted EBITDA in the same manner as we calculate the measure.

The following table presents a reconciliation of Adjusted EBITDA to our net loss, the most comparable GAAP measure, for each of the periods indicated:

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the section titled “Selected Financial and Other Data” and financial statements and related notes thereto included elsewhere in this prospectus. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those discussed below. Factors that could cause or contribute to such differences include, but are not limited to, those identified below and those discussed in the section titled “Risk Factors” included elsewhere in this prospectus.

Trulia is redefining the home search experience for consumers and changing the way that real estate professionals build their businesses. Our marketplace, delivered through the web and mobile applications, gives consumers powerful tools to research homes and neighborhoods and enables real estate professionals to efficiently market their listings and attract new clients. We believe we deliver the best home search experience by combining our superior user interface with our comprehensive database of real estate properties, local insights, and user-generated content. We offer products that provide real estate professionals with access to transaction-ready consumers and help them enhance their online presence.

Key elements of our marketplace are extensive consumer reach, an engaged base of real estate professionals and a comprehensive database of real estate information and local insights. In the six months ended June 30, 2012, we had 22.0 million monthly unique visitors, and as of June 30, 2012, we had more than 360,000 active real estate professionals in our marketplace, 21,544 of whom were paying subscribers. Our large, continually refreshed, and searchable database contains more than 110 million properties, including 4.5 million homes for sale and rent. We supplement listings data with local information on schools, crime and neighborhood amenities to provide unique insights into each community. In addition, we harness rich, insightful user-generated content from our active community of contributors, including consumers, local enthusiasts, and real estate professionals. With more than 5 million unique user contributions, we believe we have the largest collection of user-generated content on homes, neighborhoods, and real estate professionals. We deliver this information on mobile devices through our iPhone, iPad, Android, and Kindle applications and also provide tailored mobile experiences, such as GPS-based search.

We offer our products free to consumers. We deliver the “inside scoop” on homes, neighborhoods, and real estate professionals in an intuitive and engaging way, helping consumers make more informed housing decisions. For real estate professionals, we offer a suite of free and subscription products to promote themselves and their listings online, and to connect with consumers searching for homes. Our free products attract users to our marketplace and the quality of our products drives the growth of our audience and promotes deep engagement by our users. We believe this leads real estate professionals to convert to paying subscribers and brand advertisers to purchase our advertising products.

We generate revenue primarily from sales of subscription marketing products that we offer to real estate professionals. Our Trulia Pro product allows real estate professionals to receive prominent placement of their listings in our search results. With our Trulia Local Ads and Trulia Mobile Ads products, real estate professionals can purchase local advertising on our website and mobile applications, respectively, by locale and by share of a given market. We also generate revenue from display advertising we sell to leading real estate advertisers and consumer brands seeking to reach our attractive audience. Pricing for our display advertisements is based on advertisement size and position on our web page, and fees are based on a per-impression or on a per-click basis.

To date, we have focused our efforts and investments on developing and delivering superior products and user experiences, attracting consumers and real estate professionals to our marketplace, and growing our revenue. We have invested heavily to build our robust data and analytics platform, and continue to spend significantly on

technology and engineering. In 2005, we launched the initial version of our website. Since then, we have become one of the leading online real estate marketplaces in the United States by achieving key product development and business milestones that have driven our revenue and user growth, including:

We have experienced rapid growth in the past three years. In the years ended December 31, 2009, 2010, and 2011, and the six months ended June 30, 2012, we generated revenue of $10.3 million, $19.8 million, $38.5 million, and $29.0 million, respectively. During the same period, we had net losses of $7.0 million, $3.8 million, $6.2 million, and $7.6 million, respectively.

We believe that the growth of our business and our future success are dependent upon many factors including our ability to increase our audience size and user engagement, grow the number of subscribers in our marketplace, increase the value of our advertising products, and successfully invest in our growth. While each of these areas presents significant opportunities for us, they also pose important challenges that we must successfully address in order to sustain the growth of our business and improve our operating results.

Increase in Audience Size and User Engagement. We believe that increases in audience size and user engagement would make our marketplace more attractive to real estate professionals and advertisers which could lead to additional subscriptions, higher rates for our subscription products, more display advertising, and higher rates for display advertising. In order to increase our audience size and user engagement, we plan to continuously enhance and refresh our database of homes, to partner with third parties to add new and relevant local content, and to develop new features, tools, and products, each of which may increase our expenses. If we are not able to increase audience size and user engagement in our marketplace, we may not be able to increase the revenue from our subscription and display advertising products, and our operating results may be harmed.

Growth in the Number of Subscribers in our Marketplace. We believe that we will need to further penetrate the large base of more than 2.8 million real estate professionals in the United States in order to increase our

revenues and improve our operating results. As of June 30, 2012, we had more than 360,000 active real estate professionals in our marketplace, 21,544 of whom were paying subscribers. If we are able to increase the number of paying subscribers in our marketplace, we expect that this would increase our revenue and improve our operating results, and any failure to increase the number of paying subscribers in our marketplace would adversely affect our revenue and operating results. To attract additional real estate professionals to our marketplace and to encourage real estate professionals to become paying subscribers, we plan to communicate the value of our free and subscription products, to continue to offer our subscribers high-quality leads from consumers using our marketplace, to enhance and increase the ways that real estate professionals can market themselves and communicate with prospective clients in our marketplace, and to create additional value-added products to help professionals more effectively manage their leads, documents, and other key elements of their business. We expect that our expenses will increase as we take these actions to increase the number of real estate professionals and subscribers in our marketplace. In addition, our sales and marketing expenses were our largest operating expenses in 2011 and the six months ended June 30, 2012. Sales and marketing expenses reflect many of the costs that we incur in acquiring new subscribers and retaining existing subscribers, and we expect that sales and marketing expenses will continue to increase in absolute dollars as we seek to grow the number of subscribers in our marketplace.

Increase Value of Advertising Products. We intend to continue to increase the attractiveness of our display advertising products in order to increase advertiser demand and thereby increase the amount advertisers spend with us. We aim to increase the attractiveness of our advertising products through increasing the size of our audience and engagement of our users, improving our ability to select relevant content of interest to individual users, and improving the measurement tools available to advertisers to optimize their campaigns.

Investments for Growth. We expect to continue to invest in our marketplace, our infrastructure, and our personnel in order to drive future growth, as well as to pursue adjacent opportunities. We plan to continuously enhance and refresh our database of homes and make ongoing product enhancements intended to improve the user experience. We also expect to continue to make investments in our technical infrastructure to ensure that our growing user base can access our marketplace rapidly and reliably. In addition, we anticipate continuing to increase our headcount to ensure that our research and development function drives improvements in our marketplace and our sales and marketing function maximizes opportunities for growing our business and revenue. As part of our strategy, we also intend to invest in pursuing opportunities in large adjacent markets, such as rentals, mortgages, home improvement, and agent tools, and to expand our business internationally. We expect that these investments will increase our operating expenses, and that any increase in revenue resulting from these investments will likely trail the increase in expenses.

To analyze our business performance, determine financial forecasts, and help develop long-term strategic plans, we review the following key business metrics:

Marketplace Revenue. Marketplace revenue primarily consists of our fixed-fee subscription products. We currently provide two sets of products to real estate professionals on a subscription basis. The first set of products, which include Trulia Local Ads and Trulia Mobile Ads, enables real estate professionals to promote themselves on our search results pages and property details pages for a local market area. Real estate professionals purchase subscriptions to this product based upon their specified market share for a city or zip code, at a fixed monthly price, for periods ranging from one month to one year, with pricing depending on the location and the percentage of market share purchased. We price Trulia Local Ads and Trulia Mobile Ads subscriptions similarly based on geography, the share of a market, and demand. Our second set of products allows real estate professionals to receive prominent placement of their listings in our search results. Real estate professionals sign up for subscriptions to this service at a fixed monthly price for periods that generally range from one month to 12 months. We recognize our subscription revenue ratably over the term of the subscription.

Media Revenue. We derive media revenue from sales of display advertisements to real estate advertisers, such as home improvement companies and mortgage lenders. We also derive media revenue from sales of display advertisements to leading consumer brands, such as home furnishings, cable, and automotive companies. Our media products enable our customers to display advertisements to promote their brand on our website and mobile website, m.trulia.com. Pricing is based on advertisement size and position on our web page, and fees are billed monthly, based on a per impressions or a per click basis. Impressions are the number of times an advertisement is loaded on our web page, and prices are measured on a cost per thousand, or CPM, basis. Clicks are the number of times users click on an advertisement, and prices are measured on a cost per click, or CPC, basis. CPC is based on the number of times a user clicks an advertisement. This media revenue is recognized in the periods the clicks or impressions are delivered. Our media revenue is generated primarily through advertisements placed on our website, although we do generate some media revenue from display advertising on our mobile website. We price display advertisements on our mobile website on a per-impression basis. We also ran one display advertising campaign for an advertiser in November and December 2011 on our iPad mobile application, and we may offer display advertising on our other mobile applications in the future. We do not

currently generate any media revenue from our mobile applications. As our mobile web pages offer less space on which to display advertising, a shift in user traffic from our website to mobile products could decrease our advertising inventory and negatively affect our media revenue. We do not believe that we have experienced a shift in user traffic from our website to our mobile applications, as our monthly unique visitors and mobile monthly unique visitors each continued to grow at a rapid pace.

During the years ended December 31, 2009, 2010, and 2011 and the six months ended June 30, 2011 and 2012, we recognized marketplace revenue and media revenue as follows:

Both our marketplace revenue and media revenue have grown over the periods disclosed above. Our marketplace revenue has grown significantly faster than our media revenue and, as a result, now constitutes the majority of our total revenue. We expect this trend to continue and for the percentage of our media revenue, as a share of our total revenue, to continue to decline.

Cost of Revenue. Cost of revenue consists primarily of expenses related to operating our website and mobile applications, including those associated with the operation of our data center, hosting fees, customer service related headcount expenses including salaries, bonuses, benefits and stock-based compensation expense, licensed content, credit card processing fees, third-party contractor fees, and allocated overhead.

Technology and Development. Technology and development expenses consist primarily of headcount related expenses including salaries, bonuses, benefits and stock-based compensation expense, third-party contractor fees, and allocated overhead primarily associated with developing new technologies. Technology and development also includes amortization expenses related to capitalized costs from internal and external development activities for our marketplace.

Sales and Marketing. Sales and marketing expenses consist primarily of headcount-related expenses including salaries, bonuses, commissions, benefits and stock-based compensation expense for sales, customer service, marketing, and public relations employees and third-party contractor fees. Sales and marketing expenses also include other sales expenses related to promotional and marketing activities, and allocated overhead.

General and Administrative. General and administrative expenses consist primarily of headcount related expenses including salaries, bonuses, and benefits and stock-based compensation expense for executive, finance, accounting, legal, human resources, recruiting, and administrative support personnel. General and administrative expenses also include legal, accounting, and other third-party professional service fees, bad debt, and allocated overhead.

Interest income consists primarily of interest earned on our cash and cash equivalent and short-term investment balances.

Interest expense consists primarily of interest on our outstanding long-term debt and capital lease obligations. See Note 6 of our audited financial statements included elsewhere in this prospectus for more information about our long-term debt and Note 7 for more information about our capital lease obligations.

Change in the fair value of the warrant liability includes charges from the remeasurement of our preferred stock warrant liability on a mark-to-market basis as of each period end. These preferred stock warrants will remain outstanding until the earlier of the exercise or expiration of the warrants or the completion of our initial public offering, at which time, the warrant liability will be remeasured to fair value and any remaining liability will be reclassified to additional paid-in capital. See Note 9 of the audited financial statements included elsewhere in this prospectus for more information about our preferred stock warrants.

Our provision for income taxes has not been historically significant to our business as we have incurred losses to date. We currently have federal and state net operating loss carryforwards of $29.7 million and $24.9 million, which expire at various dates beginning in 2025 and 2015, respectively. See Note 12 of our audited financial statements included elsewhere in this prospectus for more information about our provision for income taxes.

The Internal Revenue Code provides limitations on our ability to utilize net operating loss carryforwards and certain other tax attributes, including tax credit carryforwards, after an ownership change, as defined in Section 382 of the Internal Revenue Code. California has similar rules that may limit our ability to utilize our state net operating loss carryforwards. If we were to experience an ownership change in the future, this could limit our use of our net operating loss carryforwards.

The following tables set forth our results of operations for the periods presented in dollars and as a percentage of our total revenue:

Revenue increased to $29.0 million in the six months ended June 30, 2012 from $16.2 million in the six months ended June 30, 2011, an increase of $12.8 million, or 78%. Marketplace revenue and media revenue represented 68% and 32%, respectively, of total revenue in the six months ended June 30, 2012, compared to 54% and 46%, respectively, of total revenue in the six months ended June 30, 2011. The continued increase in marketplace revenue as a percentage of total revenue was the result of significant growth in our subscription business. Increases in total subscribers and average monthly revenue per subscriber outpaced the growth of our advertising business.

Marketplace revenue increased to $19.7 million in the six months ended June 30, 2012 from $8.7 million in the six months ended June 30, 2011, an increase of $11.0 million, or 126%. The increase in marketplace revenue was primarily attributable to the 54% increase in the average monthly revenue per subscriber from $91 in the six months ended June 30, 2011 to $140 in the six months ended June 30, 2012, which resulted in a $5.7 million increase in marketplace revenue during the six months ended June 30, 2012 when compared to the six months ended June 30, 2011. The increase in marketplace revenue was also partly attributable to the 46% increase in the number of total subscribers from 14,766 as of June 30, 2011 to 21,544 as of June 30, 2012, which resulted in a $3.7 million increase in marketplace revenue during the six months ended June 30, 2012 when compared to the six months ended June 30, 2011.

Media revenue increased to $9.3 million in the six months ended June 30, 2012 from $7.5 million in the six months ended June 30, 2011, an increase of $1.8 million, or 23%. This increase in media revenue was primarily attributable to the increase in the number of impressions sold on a CPM or CPC basis which was primarily driven by an increase in overall advertiser demand for our display advertising inventory as we recognized an increase in monthly unique visitors from 13.4 million in the six months ended June 30, 2011 to 22.0 million in the six months ended June 30, 2012, a 64% increase. Although there is a correlation between numbers of monthly unique visitors and our media revenue, it is not a direct correlation. Therefore, and as in prior periods, the growth rate in our monthly unique visitors has outpaced the growth rate of our media revenue.

Cost of revenue increased to $4.7 million in the six months ended June 30, 2012 from $2.4 million in the six months ended June 30, 2011, an increase of $2.3 million, or 99%. This increase in cost of revenue was primarily the result of a $1.2 million increase in headcount and related benefits due primarily to growth in sales and customer service headcount following the opening of our new facility in Denver in February 2011, and a $0.9 million increase in content license fees, hosting fees, and credit card fees due to higher subscription revenue. Cost of revenue increased to 16% of revenue in the six months ended June 30, 2012 from 15% of revenue in the six months ended June 30, 2011, reflecting higher customer service-related costs in connection with the establishment of our new facility in Denver.

Technology and development expenses increased to $9.9 million in the six months ended June 30, 2012 from $6.7 million in the six months ended June 30, 2011, an increase of $3.2 million, or 49%. This increase was comprised primarily of a $2.3 million increase in headcount and related benefits, a $0.2 million increase in stock-based compensation expenses, a $0.3 million increase in facilities expenses to support our headcount growth, and a $0.2 million increase in amortization of capitalized product development costs. Technology and development expenses decreased to 34% of revenue in the six months ended June 30, 2012 from 41% of revenue in the six months ended June 30, 2011, reflecting the increase in our revenue. We expect our technology and development expenses to increase in dollar amount as we continue to invest in the development of our products.

Sales and marketing expenses increased to $15.2 million in the six months ended June 30, 2012 from $7.3 million in the six months ended June 30, 2011, an increase of $7.9 million, or 109%. This increase was primarily the result of a $5.9 million increase in headcount and related benefits associated with the expansion of our sales personnel in our new Denver facility, a $0.8 million increase in recruiting, depreciation, and facilities related expenses due to headcount growth, a $1.4 million increase in marketing and advertising expenses as we increased marketing activities for Trulia Mobile Ads, partially offset by a $0.4 million decrease in external contractor fees as we converted third-party contractors to full time employees. Sales and marketing expenses increased to 52% of revenue in the six months ended June 30, 2012 from 45% of revenue in the six months ended June 30, 2011. We expect sales and marketing expenses to increase in dollar amount as we hire additional employees to expand our sales force and to support our direct marketing initiatives.

General and administrative expenses increased to $6.0 million in the six months ended June 30, 2012 from $2.5 million in the six months ended June 30, 2011, an increase of $3.5 million, or 138%. This increase was primarily the result of a $1.6 million increase in headcount and related benefits, a $1.6 million increase in third-party professional services related to consulting and external audit services, partially offset by a $0.1 million decrease in stock-based compensation expenses. General and administrative expenses increased to 21% of revenue in the six months ended June 30, 2012 from 16% of revenue in the six months ended June 30, 2011. We expect our general and administrative expenses to increase in dollar amount as we expand our financial, accounting, and legal personnel and resources to support our anticipated public reporting requirements.

Interest expense increased to $0.5 million in the six months ended June 30, 2012 from $41,000 in the six months ended June 30, 2011. This increase was primarily the result of the incremental interest expense associated with the increased principal amount of our outstanding indebtedness during the six months ended June 30, 2012. Our indebtedness increased from $3.3 million as of June 30, 2011 to $9.7 million as of June 30, 2012. We expect that our interest expense will continue to vary in future periods based on the terms specified and amounts borrowed under our existing credit facility.

Change in fair value of warrant liability was $0.3 million in the six months ended June 30, 2012, reflecting the increase in the fair value of our outstanding preferred stock warrants. In September 2011, we issued preferred stock warrants in conjunction with establishing a new credit facility. Upon the exercise or expiration of the warrants, the conversion of the underlying shares of convertible stock, or the completion of our initial public offering, the preferred stock warrant liability will be remeasured to fair value and any remaining liability will be reclassified to additional paid-in capital. We expect the fair value of the warrants to increase leading up to our initial public offering but we do not expect any future charges following the completion of our initial public offering.

Revenue increased to $38.5 million in the year ended December 31, 2011 from $19.8 million in the year ended December 31, 2010, an increase of $18.7 million, or 95%. Marketplace revenue and media revenue represented 58% and 42%, respectively, of total revenue in the year ended December 31, 2011, compared to 47% and 53%, respectively, of total revenue in the year ended December 31, 2010. The increase in marketplace revenue as a percentage of total revenue was the result of significant growth in our subscription business, driven by increases in total subscribers and average monthly revenue per subscriber, which outpaced the growth of our advertising business.

Marketplace revenue increased to $22.3 million in the year ended December 31, 2011 from $9.4 million in the year ended December 31, 2010, an increase of $12.9 million, or 138%. This increase in marketplace revenue was primarily attributable to the 67% increase in the number of total subscribers from 10,070 as of December 31, 2010 to 16,849 as of December 31, 2011. This increase in total subscribers resulted in a $5.8 million increase in marketplace revenue during the year ended December 31, 2011 when compared to the year ended December 31, 2010. The increase in marketplace revenue was also partly attributable to a 38% increase in the average monthly revenue per subscriber from $80 in the year ended December 31, 2010 to $110 in the year ended December 31, 2011. This increase in average revenue per subscriber resulted in a $4.9 million increase in marketplace revenue during the year ended December 31, 2011 when compared to the year ended December 31, 2010.

Media revenue increased to $16.3 million in the year ended December 31, 2011 from $10.4 million in the year ended December 31, 2010, an increase of $5.9 million, or 56%. This increase in media revenue was primarily the result of the increase in the number of impressions sold on a CPM or CPC basis as we recognized an increase in overall advertiser demand for our display advertising inventory during the year ended December 31, 2011. These increases were primarily driven by an increase in our average monthly unique visitors from 7.9 million in the year ended December 31, 2010 to 14.8 million in the year ended December 31, 2011, an increase of 86%. Although there is a correlation between monthly unique visitors and our media revenue, it is not a direct correlation. Therefore, the growth rate in our monthly unique visitors has outpaced the growth rate of our media revenue.

Revenue increased to $19.8 million in the year ended December 31, 2010 from $10.3 million in the year ended December 31, 2009, an increase of $9.5 million, or 91%. Marketplace revenue and media revenue represented 47% and 53%, respectively, of total revenue in the year ended December 31, 2010, compared to 32% and 68%, respectively, of total revenue in the year ended December 31, 2009.

Marketplace revenue increased to $9.4 million in the year ended December 31, 2010 from $3.3 million in the year ended December 31, 2009, an increase of $6.1 million, or 185%. This increase in marketplace revenue was primarily attributable to the 116% increase in the number of total subscribers from 4,667 as of December 31, 2009 to 10,070 as of December 31, 2010, which was driven by our Trulia Local Ads product launch in January 2010. This increase in total subscribers resulted in a $3.7 million increase in marketplace revenue during the year ended December 31, 2010 when compared to the year ended December 31, 2009. The increase in marketplace revenue was also partly attributable to a 70% increase in the average monthly revenue per subscriber from $47 in the year ended December 31, 2009 to $80 in the year ended December 31, 2010. This increase in average revenue per subscriber resulted in a $2.9 million increase in marketplace revenue during the year ended December 31, 2010 when compared to the year ended December 31, 2009.

Media revenue increased to $10.4 million in the year ended December 31, 2010 from $7.1 million in the year ended December 31, 2009, an increase of $3.3 million, or 48%. This increase in media revenue was primarily attributable to the increase in the number of impressions sold on a CPM or CPC basis as we recognized an increase in overall advertiser demand for our display advertising inventory. We also experienced an increase in our average monthly unique visitors from 5.2 million in the year ended December 31, 2009 to 7.9 million in the year ended December 31, 2010, a 52% increase.

Cost of revenue increased to $5.8 million in the year ended December 31, 2011 from $3.7 million in the year ended December 31, 2010, an increase of $2.1 million, or 58%. This increase in cost of revenue was primarily the result of a $0.8 million increase in headcount and related benefits due to growth in customer service headcount following the establishment of our new facility in Denver in February 2011 and a $0.3 million increase in our credit card fees, a $0.2 million increase in content license fees, and a $0.4 million increase in hosting fees, due to growth in our subscriptions and additional traffic. Cost of revenue declined to 15% of revenue in the year ended December 31, 2011 from 18% of revenue in the year ended December 31, 2010.

Cost of revenue increased to $3.7 million in the year ended December 31, 2010 from $2.9 million in the year ended December 31, 2009, an increase of $0.8 million, or 28%. This increase in cost of revenue was primarily the result of a $0.4 million increase in partnership payments due to growth in media and builder advertisers and a $0.3 million increase in credit card fees due to higher subscription revenue, content license fees, and hosting fees. Cost of revenue declined to 18% of revenue in the year ended December 31, 2010 from 28% of revenue in the year ended December 31, 2009.

Technology and development expenses increased to $14.7 million in the year ended December 31, 2011 from $8.8 million in the year ended December 31, 2010, an increase of $5.9 million, or 66%. This increase was primarily the result of a $3.4 million increase in headcount and related benefits a $0.3 million increase in stock-based compensation expenses, a $0.6 million increase in equipment and facilities related costs to support the headcount growth, a $0.6 million increase related to additional recruiting and travel expenses, and a $0.3 million increase related to amortization of capitalized product development costs. Technology and development expenses declined to 38% of revenue in the year ended December 31, 2011 from 44% of revenue in the year ended December 31, 2010, reflecting the increase in our revenue.

Technology and development expenses increased to $8.8 million in the year ended December 31, 2010 from $7.1 million in the year ended December 31, 2009, an increase of $1.7 million, or 25%. This increase was primarily the result of a $1.2 million increase in headcount and related benefits expenses, a $0.3 million increase in recruiting and consulting fees, and a $0.2 million increase related to amortization of capitalized product development costs. Technology and development expenses decreased to 44% of revenue in the year ended December 31, 2010 from 68% of revenue in the year ended December 31, 2009, reflecting the increase in our revenue.

Sales and marketing expenses increased to $17.7 million in the year ended December 31, 2011 from $8.6 million in the year ended December 31, 2010, an increase of $9.1 million, or 105%. This increase was primarily the result of a $4.1 million increase in headcount and related benefits, a $2.7 million increase in consulting costs largely for temporary contractors when we opened our new Denver facility, where we subsequently hired to expand our sales team, a $1.0 million increase in facilities related costs and a $0.5 million increase in depreciation due to our growth and a $0.4 million increase in marketing and advertising expenses. Sales and marketing expenses increased to 46% of revenue in the year ended December 31, 2011 from 44% of revenue in the year ended December 31, 2010.

Sales and marketing expenses increased to $8.6 million in the year ended December 31, 2010 from $5.5 million in the year ended December 31, 2009, an increase of $3.1 million, or 56%. This increase was primarily the result of a $3.1 million increase in headcount and related benefits. Sales and marketing expenses declined to 44% of revenue in the year ended December 31, 2010 from 54% of revenue in the year ended December 31, 2009.

General and administrative expenses increased to $6.1 million in the year ended December 31, 2011 from $2.5 million in the year ended December 31, 2010, an increase of $3.6 million, or 145%. This increase was primarily the result of a $1.5 million increase in headcount and related benefits, a $0.8 million increase in professional services related to legal, recruiting, and accounting as we scaled our business, and a $0.7 million increase in stock-based compensation expenses. General and administrative expenses increased to 16% of revenue in the year ended December 31, 2011 from 13% in the year ended December 31, 2010.

General and administrative expenses increased to $2.5 million in the year ended December 31, 2010 from $1.9 million in the year ended December 31, 2009, an increase of $0.6 million, or 31%. This increase was primarily the result of a $0.2 million increase in headcount and related benefits, and a $0.2 million increase in professional services and consulting fees. General and administrative expenses decreased to 13% of revenue in the year ended December 31, 2010 from 18% of revenue in the year ended December 31, 2009.

Interest expense increased to $0.4 million in the year ended December 31, 2011 from $39,000 in the year ended December 31, 2010. This increase was primarily the result of the incremental interest expense associated with the increased principal amount of our outstanding indebtedness, which increased from $2.0 million as of December 31, 2010 to $9.6 million as of December 31, 2011.

Interest expense increased to $39,000 in the year ended December 31, 2010 from $21,000 in the year ended December 31, 2009. This increase was primarily the result of the incremental interest expense associated with the increased principal amount of our outstanding indebtedness, which increased from $0.5 million as of December 31, 2009 to $2.0 million as of December 31, 2010.

The following unaudited quarterly statements of operations data for each of the ten quarters in the period ended June 30, 2012 have been prepared on a basis consistent with our audited annual financial statements and include, in our opinion, all normal recurring adjustments necessary for the fair statement of the financial information contained in those statements. Our historical results are not necessarily indicative of the results that may be expected in the future and the results in the three and six months ended June 30, 2012 are not necessarily indicative of results to be expected for 2012 or any other period. The following quarterly financial data should be read in conjunction with our audited financial statements and the related notes included elsewhere in this prospectus.

Revenue and gross profit increased sequentially in all quarters presented. The strong increase in consumer adoption of our website and mobile applications was reflected in the significant growth in users over the periods, which contributed to substantial increases in marketplace and media revenue. Although we experienced sequential increases in media revenue during each of the eight quarters ended December 31, 2011, the growth in media revenue slowed during the year ended December 31, 2011 and media revenue decreased in the three months ended March 31, 2012. The primary reason for the decrease in media revenue during the three months ended March 31, 2012 was the loss of a significant customer which declared bankruptcy. Although the growth rate of media revenue has slowed, we expect media revenue to grow as our business grows but at a slower rate than our marketplace revenue. Accordingly, we also recognized a shift toward a greater percentage of our total revenue resulting from marketplace products as opposed to media products. The growth in our subscription business continues to outpace the growth in our advertising business and we expect this trend to continue. We have also experienced seasonality in our revenue generally as a result lower traffic in the fourth calendar quarter due to the traditionally lower volume of home sale transactions during the holiday season. In addition, our operating expenses have increased sequentially as a result of our growth, primarily related to increased headcount to support our expanded operations.

The following table presents a reconciliation of Adjusted EBITDA to our net loss, the most comparable GAAP measure, for each of the periods indicated below. See the section titled “Selected Financial and Other Data” for the detailed reconciliation to our net loss and for more information on our use and the limitations of Adjusted EBITDA as a measure of our financial performance.

Our Adjusted EBITDA fluctuated during the ten quarters in the period ended June 30, 2012. During the three months ended June 30, 2012, our net loss was the primary driver in the changes in our Adjusted EBITDA. Seasonality in our revenue in the fourth calendar quarter is also reflected in the Adjusted EBITDA for those periods.

As of June 30, 2012, our principal sources of liquidity were cash and cash equivalents totaling $9.5 million, short-term investments of $0.9 million, and $10.0 million available for draw down under our credit facility. Since inception, our operations have been financed primarily by net proceeds of $32.6 million from the sales of shares of our convertible preferred stock and $15.2 million in proceeds from the issuance of indebtedness. As of June 30, 2012, we had $9.7 million of outstanding debt on our balance sheet, which reflects a debt discount of $0.3 million.

We have incurred cumulative losses of $43.8 million from our operations to date, and expect to incur additional losses in the future. We believe that our existing sources of liquidity will be sufficient to fund our operations for at least the next 12 months. However, our future capital requirements will depend on many factors, including our rate of revenue growth, the expansion of our sales and marketing activities, and the timing and extent of our spending to support our technology and development efforts. To the extent that existing cash and cash equivalents, and cash from operations are insufficient to fund our future activities, we may need to raise additional funds through public or private equity or debt financing. Additional funds may not be available on terms favorable to us or at all.

On September 15, 2011, we entered into a loan and security agreement providing for a secured term loan facility, or the credit facility, in an aggregate principal amount of up to $20.0 million. Our ability to draw additional funds under the credit facility will expire on December 31, 2012. As of June 30, 2012, we had $10.0 million in aggregate principal outstanding under the credit facility, and an additional $10.0 million remained available to be drawn under the facility.

Amounts currently outstanding under the credit facility bear interest at floating annual rates that range from 6.0% up to the greater of (i) the prime rate plus 5.5% and (ii) 8.75%. Unless we prepay all amounts outstanding under the credit facility, we will pay accrued interest on amounts outstanding under the credit facility on a monthly basis until March 31, 2013, and beginning on April 1, 2013, we will repay the amounts outstanding under the credit facility plus all accrued interest in 30 equal monthly payments until the maturity date of September 1, 2015. We also paid certain customary fees in connection with obtaining the credit facility.

If we prepay the amounts outstanding under the credit facility in full by paying the entire outstanding principal balance, all accrued and unpaid interest, and, prior to the closing of this offering, a prepayment charge ranging from 1.0% to 3.0%, depending on the length of time the credit facility is outstanding, will become due and payable. Upon and after the closing of this offering, no prepayment charge will be payable in connection with a prepayment of the amounts outstanding under the credit facility. In addition, we must prepay the amounts outstanding under the credit facility and any prepayment charge upon a change in control.

The credit facility is secured by a security interest in substantially all of our assets. The credit facility contains customary affirmative and negative covenants, including covenants that limit or restrict our ability to, among other things, incur indebtedness, grant liens, make investments, repurchase stock, pay dividends, transfer assets, merge or consolidate, and make acquisitions.

The credit facility includes customary events of default that include, among other things, non-payment defaults, covenant defaults, the occurrence of events constituting a material adverse effect, inaccuracy of representations and warranties, bankruptcy and insolvency defaults, attachment of our assets, material judgment defaults, and cross defaults to material debt. The occurrence of an event of default could result in the acceleration of our obligations under the credit facility and a right of Hercules to exercise remedies under the credit facility, including foreclosing on the assets serving as security. During the existence of an event of default, interest on the obligations under the credit facility could be increased by five percentage points. We were in compliance with all covenants under the credit facility as of December 31, 2011 and June 30, 2012. In May 2012, we failed to comply with the covenant that required delivery of audited financial statements for the year ended December 31, 2011 within the time period set forth in the credit facility. The lender granted a waiver arising from our failure to comply with this reporting covenant. See Note 6 of the audited financial statements included elsewhere in this prospectus for more information about our credit facility.

Cash provided by operating activities in the six months ended June 30, 2012 was $1.6 million. The primary component of our cash flows during the six months ended June 30, 2012 was our net loss of $7.6 million. The cash flows from our net loss were more than offset by our non-cash operating activities and net cash flows provided through changes in certain of our operating assets and liabilities. Specifically, we recognized non-cash charges of $1.6 million for depreciation and amortization of our property and equipment, $1.0 million for stock-based compensation, and $0.3 million for the change in fair value of the preferred stock warrant liability related to preferred stock warrants issued in September 2011. We also recognized changes in operating assets and liabilities which provided $6.2 million of cash from operating activities. The primary driver of the changes in our operating assets and liabilities was a $6.2 million increase in deferred revenue due primarily to the increase the number of total subscribers and average monthly revenue per subscriber and, to a lesser extent, the launch of our latest mobile product, Trulia Mobile Ads, in May 2012. Changes in our operating assets and liabilities were also significantly affected by increases in accounts payable and accrued liabilities in the amount of $0.7 million, primarily due to the overall growth of our business, and third-party professional fees for consulting and audit services as we prepared for our initial public offering. Changes in our operating assets and liabilities were also affected by an increase in accrued compensation and benefits in the amount of $1.5 million due to the growth in our headcount and an increase in accounts receivable of $1.6 million, primarily due to our revenue growth but also due to timing of certain payments related to generally slower collections during the period.

Cash provided by operating activities for the year ended December 31, 2011 was $1.1 million. The primary component of our cash flows during the year ended December 31, 2011 was our net loss of $6.2 million. The cash flows from our net loss were more than offset by our non-cash operating activities and net cash flows provided through changes in certain of our operating assets and liabilities. Specifically, we recognized non-cash charges of $2.5 million for depreciation and amortization of our property and equipment, $1.5 million for stock-based compensation, and $0.2 million provision for doubtful accounts. We also recognized changes in operating assets and liabilities which provided $3.0 million of cash from operating activities. The primary driver of the changes in our operating assets and liabilities was a $3.0 million increase in deferred revenue due to the increase the number of total subscribers and average monthly revenue per subscriber during the year. Changes in our operating assets and liabilities were also significantly affected by an increase in accounts receivable of $1.4 million, primarily due to our revenue growth but also to timing of certain payments related to generally slower collections during the year. Changes in our operating assets and liabilities were also affected by increases in accrued compensation and benefits of $0.7 million and deferred rent of $0.7 million due to the growth in our headcount and expanded facilities during the year. Changes in our operating assets and liabilities were also affected by an increase in accounts payable and accrued liabilities in the amount of $0.4 million, due primarily to the overall growth in our business during the year.

Cash used in operating activities for the year ended December 31, 2010 was $1.1 million. The primary component of our cash flows during the year ended December 31, 2010 was our net loss of $3.8 million. The cash flows from our net loss were partially offset by our non-cash operating activities and net cash flows provided through changes in certain of our operating assets and liabilities. Specifically, we recognized non-cash

charges of $1.0 million for depreciation and amortization of our property and equipment, $0.4 million for stock-based compensation, and $0.1 million for provision for doubtful accounts. We also recognized changes in operating assets and liabilities which provided $1.3 million of cash from operating activities. The primary driver of the changes in our operating assets and liabilities was a $1.3 million increase in deferred revenue due to the increase the number of total subscribers and average monthly revenue per subscriber during the year. Changes in our operating assets and liabilities were also significantly affected by increases in accrued compensation and benefits in the amount of $0.7 million and accounts receivable of $0.7 million due primarily to our growth in headcount and revenue, respectively, during the year. Changes in our operating assets and liabilities were also affected by an increase in deferred rent of $0.4 million due primarily to the growth of our business during the year and by an increase in accounts payable and accrued liabilities of $0.3 million.

Cash used in operating activities for the year ended December 31, 2009 was $5.4 million. The primary component of our cash flows during the year ended December 31, 2009 was our net loss of $7.0 million. The cash flows from our net loss were partially offset by our non-cash operating activities and net cash flows provided through changes in certain of our operating assets and liabilities. Specifically, we recognized non-cash charges of $0.9 million for depreciation and amortization of our property and equipment, $0.3 million for stock-based compensation, and $0.1 million for provision for doubtful accounts. We also recognized changes in operating assets and liabilities which provided $0.3 million of cash from operating activities. These changes in our operating assets and liabilities were primarily as a result of increases in accounts payable and accrued liabilities aggregating to $0.3 million due to the growth in our business. These changes were offset by an increase in accounts receivable of $0.5 million due to the growth in our revenue.

Cash provided by investing activities for the six months ended June 30, 2012 was primarily related to the maturity of short-term investments in the amount of $3.4 million, partially offset by the acquisition of property and equipment in the amount of $2.2 million.

Historically, cash used in investing activities was primarily related to the acquisition of property and equipment and patents, which amounted to $0.2 million, $2.6 million, and $4.8 million for the years ended December 31, 2009, 2010, and 2011. Cash used in investing activities was also attributable to the increases in our restricted cash balance of $0.7 million, $2.1 million, and $2.2 million in the years ended December 31, 2009, 2010, and 2011.

Cash used in financing activities for the six months ended June 30, 2012 of $0.4 million was comprised of $0.6 million payment in capitalizable costs related to our initial public offering and $0.2 million of capital lease payments, partially offset by proceeds of $0.3 million from the exercise of stock options.

Cash provided by financing activities for the year ended December 31, 2011 of $8.2 million was primarily comprised of proceeds of $12.0 million from additional borrowings and $0.4 million from exercise of stock options, which were partially offset by $4.2 million of capital lease and long-term debt repayments.

Cash provided by financing activities for the year ended December 31, 2010 of $1.4 million was primarily comprised of proceeds of $2.1 million from additional borrowings which were partially offset by $0.8 million of capital lease and long-term debt repayments.

Cash used in financing activities for the year ended December 31, 2009 of $0.1 million was primarily comprised of $0.3 million of capital lease and long-term debt repayments, which were partially offset by proceeds of $0.2 million from additional borrowings.

The following table summarizes our contractual obligations as of December 31, 2011:

We had unrecognized tax benefits in the amount of $0.5 million as of December 31, 2011 related to uncertain tax positions. However, there is uncertainty regarding when these liabilities will require settlement so these amounts were not included in the contractual obligations table above.

We made regular rent payments under our noncancelable operating leases and capital leases during the six months ended June 30, 2012. We did not enter into any new material agreements during the period.

During the six months ended June 30, 2012, we achieved certain financial milestones under our credit facility, which resulted in the extension of the beginning of the interest-only repayment period from September 2012 to March 2013 and the maturity date from March 2015 to September 2015.

We have not entered into any off-balance sheet arrangements and do not have any holdings in variable interest entities.

We are exposed to certain market risks in the ordinary course of our business. These risks primarily include interest rate sensitivities as follows:

We had cash and cash equivalents of $9.5 million as of June 30, 2012, which consists of bank deposits and money market funds. Such interest-earning instruments carry a degree of interest rate risk. To date, fluctuations in interest income have not been significant. We also had total outstanding debt of $9.7 million as of June 30, 2012, of which $0.8 million is due within 12 months. Amounts outstanding under our credit facility carry variable interest rates ranging from 6.0% to 8.75%.

We do not enter into investments for trading or speculative purposes and have not used any derivative financial instruments to manage our interest rate risk exposure. We have not been exposed to, nor do we anticipate being exposed to, material risks due to changes in interest rates. The interest rate on our outstanding debt is variable, which also reduces our exposure to these interest rate risk. A hypothetical 10% change in interest rates during any of the periods presented would not have had a material impact on our financial statements.

Our financial statements are prepared in accordance with generally accepted accounting principles in the United States, or GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses, and related disclosures. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable. In many instances, we could have reasonably used different accounting estimates, and in other instances changes in the accounting estimates are reasonably likely to occur from period-to-period. Actual results could differ significantly from our estimates. To the extent that there are material differences between these estimates and actual results, our future financial statement presentation, financial condition, results of operations and cash flows will be affected. We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving our judgments and estimates.

We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price to the buyer is fixed or determinable, and collection is reasonably assured. We consider a signed agreement, a binding insertion order, or other similar documentation reflecting the terms and conditions under which products will be provided to be persuasive evidence of an arrangement. Collectability is assessed based on a number of factors, including payment history and the creditworthiness of a customer. If it is determined that collection is not reasonably assured, revenue is not recognized until collection becomes reasonably assured, which is generally upon receipt of cash.

Our revenue includes marketplace revenue and media revenue. Marketplace revenue consists primarily of subscription revenue, which is recognized ratably over the term of the subscription. Media revenue consists primarily of advertisement sales, which is recognized in the periods the clicks or impressions are delivered.

We also enter into arrangements with customers that include combinations of CPC or CPM media placements and subscription products. Beginning on January 1, 2011, we adopted new authoritative guidance on multiple-element arrangements, using the prospective method for all arrangements entered into or materially modified from the date of adoption. Under this new guidance, we allocate arrangement consideration in multiple-element revenue arrangements at the inception of an arrangement to all deliverables or those packages in which all components of the package are delivered at the same time, based on the relative selling price method in accordance with the selling price hierarchy, which includes: (i) vendor-specific objective evidence, or VSOE, if available; (ii) third-party evidence, or TPE, if VSOE is not available, and (iii) best estimate of selling price, or BESP, if neither VSOE nor TPE is available.

VSOE- We determine VSOE based on our historical pricing and discounting practices for the specific product when sold separately. In determining VSOE, we require that a substantial majority of the standalone selling prices for these products fall within a reasonably narrow pricing range. For certain subscription products, we have been able to establish VSOE.

TPE- When VSOE cannot be established for deliverables in multiple-element arrangements, we apply judgment with respect to whether we can establish a selling price based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. Generally, our go-to-market strategy differs from that of our peers and our offerings contain a significant level of differentiation such that the comparable pricing of our products cannot be obtained. Furthermore, we are unable to reliably determine what similar competitor selling prices are on a standalone basis. As a result, we have not been able to establish selling price based on TPE.

BESP- When we are unable to establish selling price using VSOE or TPE, we use BESP in the allocation of arrangement consideration. The objective of BESP is to determine the price which we would transact a sale

if the service were sold regularly on a standalone basis. As we have not been able to establish VSOE or TPE for CPM and CPC products and certain subscription products, we determine BESP for these deliverables based on the following:

We limit the amount of allocable arrangement consideration to amounts that are fixed or determinable and that are not contingent on future performance or future deliverables. We regularly review BESP. Changes in assumptions or judgments or changes to the elements in the arrangement could cause a material increase or decrease in the amount of revenue that we report in a particular period.

We record a provision for doubtful accounts based on historical experience and a detailed assessment of the collectability of our accounts receivable. To assist with the estimate, our management considers certain factors such as historical experience, industry data, credit quality, age of accounts receivable balances, and current economic conditions that may affect a customer’s ability to pay. In cases where we become aware of circumstances that may impair a specific customer’s ability to meet its financial obligations, we record a specific allowance against amounts due from the customer and thereby reduce the net recognized receivable to the amount we reasonably believe will be collected. There is significant judgment involved in estimating the allowance for doubtful accounts.

We assess the impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is measured first by a comparison of the carrying amount of an asset to the future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, an impairment loss would be recognized. When measuring the recoverability of these assets, we will make assumptions regarding our estimated future cash flows expected to be generated by the assets. If our estimates or related assumptions change in the future, we may be required to impair these assets. We have not recognized any impairment of long-lived assets to date.

Costs incurred in connection with the development of our marketplace are accounted for as follows: all costs incurred in the preliminary project and post-implementation stages are expensed as incurred. Certain costs incurred in the application development stage of a new product or projects to provide significant additional functionality to existing products are capitalized if certain criteria are met. Maintenance and enhancement costs are typically expensed as incurred. Such costs are amortized on a straight-line basis over the estimated useful lives of the related assets, which was estimated to be two years. Amortization expense is included in technology and development expense in the statements of operations.

We recognize compensation costs related to stock options granted to employees based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures. We estimate the grant date fair value, and the resulting stock-based compensation expense using the Black-Scholes option-pricing model. The grant date fair value of the stock-based awards is recognized on a straight-line basis over the requisite service period, which is the vesting period of the respective awards.

The fair value of the awards granted during the years ended December 31, 2009, 2010, and 2011 and the six months ended June 30, 2011 and 2012 was calculated using the Black-Scholes option-pricing model with the following weighted average assumptions:

The Black-Scholes option-pricing model requires the use of highly subjective and complex assumptions, including the expected term and the price volatility of the underlying stock, which determine the fair value of stock-based awards. These assumptions include:

In addition to the assumptions used in the Black-Scholes option-pricing model, we must also estimate a forfeiture rate to calculate the stock-based compensation for our awards. Our forfeiture rate is based on an

analysis of our actual forfeitures. We will continue to evaluate the appropriateness of the forfeiture rate based on actual forfeiture experience, analysis of employee turnover, and other factors. Quarterly changes in the estimated forfeiture rate can have a significant impact on our stock-based compensation expense as the cumulative effect of adjusting the rate is recognized in the period the forfeiture estimate is changed. If a revised forfeiture rate is higher than the previously estimated forfeiture rate, an adjustment is made that will result in a decrease to the stock-based compensation expense recognized in our financial statements. If a revised forfeiture rate is lower than the previously estimated forfeiture rate, an adjustment is made that will result in an increase to the stock-based compensation expense recognized in our financial statements.

We will continue to use judgment in evaluating the expected volatility, expected terms, and forfeiture rates utilized for our stock-based compensation calculations on a prospective basis. As we continue to accumulate additional data related to our common stock, we may have refinements to the estimates of our expected volatility, expected terms, and forfeiture rates, which could materially impact our future stock-based compensation expense.

We are also required to estimate the fair value of the common stock underlying our stock-based awards when performing the fair value calculations with the Black-Scholes option-pricing model. The fair value of the common stock underlying our stock-based awards was estimated on each grant date by our board of directors, with input from management. Our board of directors is comprised of employee and non-employee directors with significant experience investing in and operating companies in the real estate and technology industries. As such, we believe that our board of directors has the relevant experience and expertise to determine a fair value of our common stock on each respective grant date. Given the absence of a public trading market of our common stock, and in accordance with the American Institute of Certified Public Accountants Practice Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation, our board of directors exercised reasonable judgment and considered numerous objective and subjective factors to determine the fair value of our common stock including:

The independent valuations performed by unrelated third-party specialists were just one factor used by our board of directors to assist with the valuation of the common stock and our management and board of directors have assumed full responsibility for the estimates. Our board of directors generally utilized the fair values of the common stock derived in the third-party valuations in determining the exercise price for options granted.

In valuing our common stock, our board of directors considered two valuation approaches to determine the equity value of our business, an income approach and a market approach.

The income approach estimates the fair value of a company based on the present value of the company’s future estimated cash flows and the residual value of the company beyond the forecast period. These future values are discounted to their present values to reflect the risks inherent in the company achieving these estimated cash flows. The discount rates are used in the income approach for early stage companies because these companies tend to be relatively risky investments and therefore command rates of return commensurate with such risk. The discount rates used in our valuation were based primarily on benchmark venture capital studies of discount rates for other companies in our stage of development, considered along with industry based weighted average cost of capital rates. Other significant inputs of the income approach (in addition to our estimated future cash flows themselves) include but are not limited to the long-term growth rate assumed in the residual value and normalized long-term operating margin. The market approach estimates the fair value of a company by applying market multiples of comparable publicly traded companies in the same industry or similar lines of business. More specifically, we selected our comparable publicly traded companies by analyzing various factors, including, but not limited to, industry similarity, financial risk, company size, geographic diversification, profitability, the availability of adequate financial data, and whether or not they had an actively traded stock price. The market multiples are based on key metrics implied by the enterprise or acquisition values of comparable publicly traded companies and, for our valuations in 2012, we primarily utilized the last twelve months and projected twelve months revenue multiples from our comparable publicly traded peers in the market approach. These observed multiples were averaged and then applied to our historical twelve months and projected revenue to arrive at an indication of value. We deemed multiples of revenue to be the most relevant in our industry as we are still in a relatively high growth phase, and thus have not reached normalized profitability or generated positive historical profit thus making the application of profit based multiples not possible or less reliable. Other significant inputs of the market approach include historical and projected operating metrics. Our third-party valuations for the year ended December 31, 2011 discussed below used only an income approach because we were an operating entity expected to generate future cash flows for our owners and any future sale of or transaction to purchase our business would likely be based on our future cash flow expectations. In addition, we were not generating sufficient operating metrics, consisting primarily of revenue, as compared to our publicly traded peer companies to generate meaningful results from the market approach at the time of the 2011 valuations. For the valuations from the year ending December 31, 2012, we have thus far used both the income approach and the market approach with the respective values weighted appropriately. The market approach was added to the 2012 valuations as a result of our revenue growth and growth in maturity and size compared to our publicly traded peer companies and also as our board began preparations for an initial public offering.

The enterprise value determined by the income and market approach was then allocated to the common stock using the option pricing method. The option pricing method, or OPM, treats common stock and convertible preferred stock as call options on a business, with exercise prices based on the liquidation preference of the convertible preferred stock. Therefore, the common stock has value only if the funds available for distribution to the stockholders exceed the value of the liquidation preference at the time of a liquidity event such as a merger, sale or initial public offering, assuming the business has funds available to make a liquidation preference meaningful and collectible by the stockholders. The common stock is modeled to be a call option with a claim on the business at an exercise price equal to the remaining value immediately after the convertible preferred stock is liquidated. The OPM uses the Black-Scholes option-pricing model to price the call option. The OPM is appropriate to use when the range of possible future outcomes is so difficult to predict that forecasts would be highly speculative. The probability weighted expected return method, or PWERM, was considered but not used due to the uncertainty of our estimates of the probabilities for future potential liquidity events.

Information regarding stock awards granted to our employees since April 1, 2011 is summarized as follows:

No single event caused the valuation of our common stock to increase through July 2012. Instead, a combination of the following factors, described in greater detail in the individual valuation discussions below, led to the changes in the fair value of the underlying common stock as determined by our board of directors. Primarily, the increase was attributable to business developments during this intervening period. Specifically, our subscribers, visitors, and revenue were primarily increasing during this period. In addition to the increase as a result of business developments, the increase was a result of our progress towards an initial public offering, including discussions with prospective underwriters and an organizational meeting in April 2012. In addition, the global economies as well as the stock markets, including the market for initial public offerings, improved through the first quarter of 2012.

To assist our board of directors with the determination of the exercise price for our stock options and the fair value of the common stock underlying the options, we obtained third-party valuations of our common stock as of February 28, June 30, September 30, and December 31, 2011, and as of February 29, April 30, May 31, and July 13, 2012. An analysis of our valuations and determinations of the exercise price and the fair value of the underlying common stock for our stock-based awards granted on or between the respective valuation dates are discussed further below.

We granted 574,587 options on May 11, 2011 and 677 options on June 20, 2011. Our board of directors set an exercise price of $4.29 per share for these options based in part on a contemporaneous third-party valuation prepared as of February 28, 2011. To calculate the stock-based compensation expense for these options, we also used the fair value as determined in the February 28, 2011 valuation of $4.29 per share as the fair value of the underlying common stock for these options.

The February 28, 2011 contemporaneous valuation was prepared on a minority, non-marketable basis assuming our business was in the expansion stage of development. We considered our business to be in the expansion stage of development because we were gaining traction in our industry although our future growth rates were still uncertain. Also, companies within the expansion stage of development are generally growing quickly and producing positive profit margins which help reduce the downside risk to potential investors. However, this growth generally requires more working capital than can be generated from internal cash flows. The expansion stage of development is generally for companies more mature than companies determined to be either start-up or early stage of development, but less mature than companies in the rapid growth or mezzanine stage of development.

our historical financial statements. The forecasted cash flows represent the economics that both a minority and controlling shareholder would be able to realize and therefore were assumed to represent both a control and minority premise of value. In addition, the discount rate was developed considering the capital structure of the industry and the long-term expected capital structure of our business. The valuation used a discount rate of 35%. The discount rate of 35% used in this valuation was based primarily on benchmark venture capital studies of discount rates for other companies in the expansion stage of development, considered along with industry based weighted average cost of capital rates.

The aggregate equity value was allocated to the common stock utilizing an OPM with the following assumptions: a time to a liquidity event of two years, risk-free rate of 0.67%, dividend yield of 0%, and volatility of 65% over the time to a liquidity event. The time to a liquidity event was determined based on the expectation of our board of directors of us completing an initial public offering, the risk-free rate was based on the U.S. Treasury yield curve in effect at the time of grant for zero coupon U.S. Treasury notes with maturities of two years, the dividend yield was zero based on the expectation of our board of directors regarding future dividends, and the volatility was based on the historical volatility of our comparable peer companies, consisting of the eight technology companies that were determined to be the most comparable to our business, over a two year period. The fair value of our common stock, as determined by an OPM and after applying a marketability discount of 25%, was $4.29 per share. The marketability discount, which has a negative impact on the fair value of the common stock, was based on empirical evidence from multiple sources which incorporated studies of companies with outstanding restricted stock who also have unrestricted shares that are freely traded and studies of different private transactions which occurred prior to a company’s initial public offering. Based on these studies and our stage of development, a 25% marketability discount was determined to be appropriate. Our board of directors decided not to increase the fair value between February 28, 2011 and these options grants as they were not aware of any evidence that would require revision to the fair value determined as of February 28, 2011.

We granted 185,220 options on September 1, 2011. Our board of directors set an exercise price of $4.59 per share for these options based in part on a third-party valuation prepared as of June 30, 2011. The June 30, 2011 valuation was prepared on a minority, non-marketable basis assuming our business was still in the expansion stage of development as we were still growing quickly and producing positive profit margins but also generally still in need of more working capital than we could generate from operations.

This valuation was developed using the income approach, specifically a discounted cash flow analysis, to determine the value of our business. The discounted cash flow analysis was developed based on our forecast and our historical financial statements. The valuation used a discount rate of 32.5%. The discount rate of 32.5% used in this valuation was based primarily on benchmark venture capital studies of discount rates for other companies in the expansion stage of development. Based on the results of these studies and other factors such as an increase in our current projections and the reduction in the potential time to a liquidity event, we determined a slightly reduced discount rate of 32.5% which was still consistent with the benchmark studies. The reduction in the discount rate resulted in an increase in the fair value of the common stock, as generally a reduced discount rate will result in higher equity values.

The aggregate equity value was allocated to the common stock utilizing an OPM with the following assumptions: a time to a liquidity event of 1.75 years, risk-free rate of 0.43%, dividend yield of 0%, and volatility of 65% over the time to a liquidity event. Both the time to a liquidity event and the comparable peer companies used to determine the volatility remained consistent with the February 28, 2011 valuation. The fair value of our common stock, as determined by an OPM and after applying a marketability discount of 25%, was $4.50 per share as of June 30, 2011. However, our board of directors decided to increase the exercise price slightly to $4.59 per share due to continued improvements in the business during the intervening period. The increase in the fair value from the February 28, 2011 valuation of $4.29 per share to the fair value of $4.59 per share was primarily due to the reduction in the time to a liquidity event due to the passage of time and the related reduction in the discount rate.

We granted 470,787 options on November 9, 2011 and 88,333 options on November 17, 2011. Our board of directors set an exercise price of $5.55 per share for these options based in part on a third-party valuation prepared as of September 30, 2011. The September 30, 2011 valuation was prepared on a minority, non-marketable basis assuming our business was still in the expansion stage of development.

This valuation was developed using the income approach, specifically a discounted cash flow analysis, to determine the value of our business. The discounted cash flow analysis was developed based on our forecast and our historical financial statements. The valuation used a discount rate of 30%. The discount rate of 30% used in this valuation was based primarily on benchmark venture capital studies of discount rates for other companies in the expansion stage of development. Based on the results of these studies and other factors such as an increase in our current projections and the reduction in the potential time to a liquidity event due to the passage of time, we determined a discount rate of 30% which was slightly lower than but still consistent with the benchmark studies. The reduction in the discount rate resulted in an increase in the fair value of the common stock.

The aggregate equity value was allocated to the common stock utilizing an OPM with the following assumptions: a time to a liquidity event of 1.25 years, risk-free rate of 0.17%, dividend yield of 0% and volatility of 55% over the time to a liquidity event. The time to a liquidity event was accelerated by three months from the estimate used in the June 30, 2011 valuation based on the expectation of our board of directors of the timing for an initial public offering while the comparable peer companies used to determine the volatility remained consistent with the June 30, 2011 valuation. The fair value of our common stock, as determined by an OPM and after applying a marketability discount of 20%, was $5.55 per share as of September 30, 2011. Our board of directors decided not to increase the exercise price between November 9 and the November 17, 2011 options as they were not aware of any evidence that would require revision to the fair value determined as of September 30, 2011.

The marketability discount was reduced from 25% in the June 30, 2011 valuation to 20% for the September 30, 2011 valuation due to the reduction in the estimated time to a liquidity event. In addition to the decrease in the marketability discount, the reduction in the estimated time to a liquidity event, and the reduced volatility all had a positive effect on the fair value of the common stock between the June 30, 2011 and September 30, 2011 valuations. Also, general improvements in our business during this period resulted in revised forecast and reduced discount rate for our discounted cash flow analysis which increased the fair value of our common stock from the June 30, 2011 valuation to the September 30, 2011 valuation.

We granted 151,563 options on February 13, 2012. Our board of directors set an exercise price of $6.81 per share for these options based in part on a third-party valuation prepared as of December 31, 2011. The December 31, 2011 valuation was prepared on a minority, non-marketable basis assuming our business was in the rapid growth stage of development. We considered our business to be in the rapid growth stage of development because we are growing rapidly and we expect a liquidity event within the coming years but the timing and form are still uncertain. In addition, we may need more cash to sustain this growth but we are generally successful and stable enough to reduce downside risk to potential investors. The rapid growth stage of development is generally for companies more mature then earlier stage companies which would generally fall within either the start-up, early development, or expansion stage of development, but less mature than companies in the mezzanine stage of development.

This valuation was developed using the income approach, specifically a discounted cash flow analysis, to determine the value of our business. The discounted cash flow analysis was developed based on our forecast and our historical financial statements. The valuation utilized a discount rate of 30%, consistent with the September 30, 2011 valuation, even though we transitioned to the rapid growth stage of development as 30% was still within the ranges provided by benchmark venture capital studies of discount rates for other companies in the rapid growth stage of development. Based on the results of these studies and other factors such as an increase in our current projections, we determined a discount rate of 30% was appropriate for this valuation.

The aggregate equity value was allocated to the common stock utilizing an OPM with the following assumptions: a time to a liquidity event of one year, risk-free rate of 0.13%, dividend yield of 0%, and volatility of 55% over the time to a liquidity event. The estimated date of a liquidity event remained consistent with the September 30, 2011 valuation, however, the comparable peer companies were updated to include one newly listed company in our industry. The fair value of our common stock, as determined by an OPM and after applying a marketability discount of 15%, was $6.81 per share as of December 31, 2011. Our board of directors decided not to increase the exercise price for the February 2012 options as they were not aware of any evidence that would require revision to the fair value determined in the December 31, 2011 valuation.

The marketability discount was reduced from 20% in the September 30, 2011 valuation to 15% for the December 31, 2011 valuation due to the additional reduction in the estimated time to a liquidity event due to the passage of time, which had a positive effect on the fair value of our common stock. Also, general improvements in our business during this period resulted in revised forecast for our discounted cash flow, which increased the fair value of our common stock from the September 30, 2011 valuation to the December 31, 2011 valuation.

We granted 64,964 options on March 20, 2012. Our board of directors set an exercise price of $9.42 per share for these options based in part on a third-party valuation prepared as of February 29, 2012. The February 29, 2012 valuation was prepared on a minority, non-marketable basis assuming our business was in the mezzanine stage of development. We considered our business to be in the mezzanine stage of development because we were in the early phases of planning for our initial public offering and we did not anticipate raising additional funds prior to an initial public offering.

This valuation was developed using the income approach, specifically a discounted cash flow analysis, and the market approach to determine the value of our business. The discounted cash flow analysis was developed based on our forecast and our historical financial statements. The market approach estimate was developed by applying market multiples of comparable peer companies in our industry or similar lines of business. For the February 29, 2012 contemporaneous valuation, we used multiples of an adjusted market value to both the last twelve months’ revenue and forecasted twelve months revenue. The valuation used a discount rate of 20% which was a reduction from the 30% discount rate used in the December 31, 2011 valuation. The discount rate was reduced to 20% primarily as a result of our transition to the mezzanine stage of development. As a result of this transition, our discount rate is now based primarily on benchmark venture capital studies of discount rates for other companies in the mezzanine stage of development. We also considered industry-based weighted average cost of capital rates. Based on the results of these studies and other factors such as an increase in our current projections and the reduction in the potential time to a liquidity event, we settled on a discount rate of 20% which was slightly lower than the benchmark studies but higher than the industry based weighted average cost of capital. The reduction in the discount rate resulted in an increase in the fair value of the common stock. In addition, we also recognized increases in the fair value of our common stock in our market approach analysis as a result of an increase in our observed revenue multiples as well as the continued growth in business.

During this period, we revised our list of comparable publicly traded companies by analyzing various factors, including, but not limited to, industry similarity, financial risk, company size, geographic diversification, profitability, the availability of adequate financial data, and whether or not it had an actively traded stock price. As a result of this analysis, we determined that we had just two “pure-play” comparables that are directly competing market participants with substantially similar business and monetization models. The last twelve months and projected twelve months revenue multiples for both companies were therefore directly relied upon and applied in the market approach used in the February 29, 2012 valuation. These observed multiples were averaged and then applied to our historical twelve months and projected revenue to arrive at an indication of value. We deemed multiples of revenue to be the most relevant in our industry as we are still in a relatively high growth phase similar to our comparable peer companies, and thus have not reached normalized profitability or generated positive historical profit thus making the application of profit based multiples not possible or less reliable. In addition, we did consider a broader group of comparable peer companies along with the “pure-play”

comparables for purposes of estimating industry based cost of capital, volatility, and other financial benchmarking, and these companies were the same that were utilized in the September 30, 2011 and December 31, 2011 valuations.

The values determined by the income approach and the market approach were combined, weighting the income approach value by 80% while only weighting the market approach value by 20%. The aggregate value was then allocated to the common stock utilizing an OPM with the following assumptions: a time to a liquidity event of 0.85 years, risk-free rate of 0.15%, dividend yield of 0%, and volatility of 70% over the time to a liquidity event. The time to a liquidity event remained consistent with the December 31, 2011 valuation. The fair value of our common stock, as determined by an OPM and after applying a marketability discount of 15%, was $9.42 per share as of February 29, 2012 and, consistent with the prior practice of our board of directors of using a fair value similar to that determined by the most recent, prior contemporaneous valuation as the exercise price for our options, our board of directors used this value for the exercise price for the options granted in March 2012. The increase in the fair value of our common stock was primarily due to the continued growth of our business and improvements in our results during this period which generally resulted in our progression towards an initial public offering and the reduced time to such an event, a decrease in the discount rate primarily related to our transition to the mezzanine stage of development, and a shift towards including a weighted value determined from the market approach within this valuation.

We granted 92,405 options on May 8, 2012. Our board of directors set an exercise price of $12.15 per share for these options based in part on a third-party valuation prepared as of April 30, 2012. The April 30, 2012 valuation was prepared on a minority, non-marketable basis assuming our business was in the mezzanine stage of development as the initial public offering was formally kicked off and progressing during this intervening period and we were also projecting positive operating results.

This valuation was developed using the income approach, specifically a discounted cash flow analysis, and the market approach to determine the value of our business. The discounted cash flow analysis was developed based on our forecast and our historical financial statements. The market approach estimate was developed by applying market multiples of comparable peer companies in our industry or similar lines of business. For the April 30, 2012 contemporaneous valuation, we used multiples of an adjusted market value to both the last twelve months revenue and forecasted twelve months revenue. The valuation used a discount rate of 18% which was lower than the rates seen in the benchmark venture capital studies of discount rates for other companies in the mezzanine stage of development but still higher than the industry based weighted average cost of capital. We chose to lower the discount rate slightly as we continued to progress towards an initial public offering which coincided with the shorter time to a liquidity event than was used in the February 13, 2012 valuation due to the passage of time. The reduction in the discount rate resulted in a small increase in the fair value of the common stock. In addition, we also recognized increases in the fair value of our common stock in our market approach as a result of an increase in our observed multiples of revenue, our projected revenue, and the continued growth in our historical revenue, primarily on a trailing twelve month basis. Also, our comparable publicly traded peer companies did not change from the companies used in the February 13, 2012 valuation.

The values determined by the income approach and the market approach were then combined, weighting the income approach value by 70% while only weighting the market approach value by 30%. The weighting of the market approach was increased to 30% from 20% used in the February 13, 2012 valuation. This increase in weighting toward the market approach is consistent with the reduction in the discount rate over the same period. As we have held our long-term forecasted cash flow projections constant during 2012, the decrease in discount rate was used to closer reconcile the indications of value between the market approach and income approach and reflect our progress towards a potential initial public offering. The aggregate value was then allocated to the common stock utilizing an OPM with the following assumptions: a time to a liquidity event of 0.67 years, risk-free rate of 0.17%, dividend yield of 0% and volatility of 60% over the time to a liquidity event. The time to a

liquidity event remained consistent with the February 29, 2012 valuation. The fair value of our common stock, as determined by an OPM and after applying a marketability discount of 11%, was $12.15 per share as of April 30, 2012 and, consistent with the prior practice of our board of directors of using a fair value similar to that determined by the most recent, prior contemporaneous valuation as the exercise price for our options, our board of directors used this value for the exercise price for the options granted in May 2012. The reduction in the marketability discount from 15% in the February 13, 2012 valuation to 11% in this valuation, which had a positive impact on the fair value of the common stock, was due to our progress towards an initial public offering as well as indications from a quantitative model that indicates a lower discount as the assumed time horizon and volatility decreases. Therefore, the increase in the fair value of our common stock was primarily due to the continued growth of our business and improvements in our results during this period which generally resulted in our progression towards an initial public offering and the reduced time to such an event, a decrease in the discount rate and the marketability discount, a decrease in volatility of our comparable publicly traded peers, and a shift towards a heavier weighting of the value determined from the market approach.

We granted 99,062 options on June 5, 2012. Our board of directors set an exercise price of $13.32 per share for these options based in part on a third-party valuation prepared as of May 31, 2012. The May 31, 2012 valuation was prepared on a minority, non-marketable basis assuming our business was in the mezzanine stage of development as the initial public offering was still progressing at this time.

This valuation was developed using the income approach, specifically a discounted cash flow analysis, and the market approach to determine the value of our business. The discounted cash flow analysis was developed based on our forecast and our historical financial statements. The market approach estimate was developed by applying market multiples of comparable peer companies in our industry or similar lines of business. For the May 31, 2012 contemporaneous valuation, we used multiples of an adjusted market value to both the last twelve months revenue and forecasted twelve months revenue. The valuation used a discount rate of 17% which was lower than the rates seen in the benchmark venture capital studies of discount rates for other companies in the mezzanine stage of development but still higher than the industry based weighted average cost of capital. We chose to lower the discount rate slightly as we continued to progress towards an initial public offering which coincided with the shorter time to a liquidity event since the April 30, 2012 valuation due to the passage of time. In addition, we also recognized increases in the fair value of our common stock in our market approach as a result of an increase in our observed revenue multiples, our projected revenue, and the continued growth in our historical revenue, primarily on a trailing twelve month basis. Also, our comparable publicly traded peer companies did not change from the companies used in the April 30, 2012 valuation.

The values determined by the income approach and the market approach were then combined, weighting the income approach value by 70% while only weighting the market approach value by 30%. The weighting of the market approach was not changed from the weighting used in the April 30, 2012 valuation as we did not feel that there were significant enough changes in the month since the prior valuation, including only a 1% reduction in the discount rate, that should result in a reassessed allocation at this time. The aggregate value was then allocated to the common stock utilizing an OPM with the following assumptions: a time to a liquidity event of 0.59 years, risk-free rate of 0.15%, dividend yield of 0% and volatility of 55% over the time to a liquidity event. The time to a liquidity event remained consistent with the April 30, 2012 valuation. The fair value of our common stock, as determined by an OPM and after applying a marketability discount of 10%, was $13.32 per share as of May 31, 2012 and, consistent with the prior practice of our board of directors of using a fair value similar to that determined by the most recent, prior contemporaneous valuation as the exercise price for our options, our board of directors used this value for the exercise price for the options granted in June 2012. The reduction in the marketability discount from 11% in the April 30, 2012 valuation to 10% in this valuation, which had a positive impact on the fair value of the common stock, was due to our continuing progress towards an initial public offering. Therefore, the increase in the fair value of our common stock was primarily due to the continued growth of our business and improvements in our results during this period which generally resulted in our progression

towards an initial public offering and the reduced time to such an event, a decrease in the discount rate and marketability discount, and a decrease in volatility of our comparable publicly traded peers.

We granted 149,124 options on July 19, 2012 and 253,410 options on July 27, 2012. Our board of directors set an exercise price of $16.53 per share for these options based in part on a third-party valuation prepared as of July 13, 2012. The July 13, 2012 valuation was prepared on a minority, non-marketable basis assuming our business was in the mezzanine stage of development as the initial public offering was still progressing at this time and we were projecting positive operating results.

This valuation was developed using the income approach, specifically a discounted cash flow analysis, and the market approach to determine the value of our business. The discounted cash flow analysis was developed based on our forecast and our historical financial statements. The market approach estimate was developed by applying market multiples of comparable peer companies in our industry or similar lines of business. For the July 13, 2012 contemporaneous valuation, we used multiples of an adjusted market value to both the last twelve months revenue and forecasted twelve months revenue. The valuation used a discount rate of 15% which was lower than the rates seen in the benchmark venture capital studies of discount rates for other companies in the mezzanine stage of development but still higher than the industry based weighted average cost of capital. We chose to lower the discount rate as we continued to progress towards an initial public offering which coincided with the shorter time to a liquidity event. In addition, we also recognized increases in the fair value of our common stock in our market approach as a result of an increase in our observed multiples of revenue as well as the continued growth in our historical revenue, primarily on a trailing twelve month basis. Also, our comparable publically traded peer companies did not change from the companies used in the May 2012 valuation.

The values determined by the income approach and the market approach were then combined, weighting the income approach value by 60% while only weighting the market approach value by 40%. The weighting of the market approach was increased to 40% from 30% used in the May 2012 valuation. This increase in weighting toward the market approach is consistent with the reduction in the discount rate over the same period. As we have held our long-term forecasted cash flow projections constant during 2012, the decrease in discount rate was used to closer reconcile the indications of value between the market approach and income approach and reflect our progress towards a potential initial public offering. The aggregate value was then allocated to the common stock utilizing an OPM with the following assumptions: a time to a liquidity event of 0.22 years, risk-free rate of 0.10%, dividend yield of 0%, and volatility of 60% over the time to a liquidity event. The time to a liquidity event was accelerated as a result of our expected timing for an initial public offering. The fair value of our common stock, as determined by an OPM and after applying a marketability discount of 6%, was $16.53 per share as of July 13, 2012 and, consistent with the prior practice of our board of directors of using a fair value similar to that determined by the most recent, prior contemporaneous valuation as the exercise price for our options, our board of directors used this value for the exercise price for the options granted in July 2012. The reduction in the marketability discount from 10% in the May 2012 valuation to 6% in this valuation, which had a positive impact on the fair value of the common stock, was due to our continuing progress towards an initial public offering. Therefore, the increase in the fair value of our common stock was primarily due to the continued growth of our business and improvements in our results during this period which generally resulted in our progression towards an initial public offering and the reduced time to such an event. The increase was also attributable to the decrease in the discount rate and marketability discount as well as an increase in the observed multiples of our comparable publicly traded peers.

In September 2012, our underwriters communicated to us an estimated offering price range of $14.00 to $16.00 per share of common stock to be sold in this offering. This estimate was based upon valuation information regarding comparable companies and an equity market analysis prepared by the underwriters. After

considering the estimated offering price range and other factors, our board of directors concluded that the midpoint of the estimated offering price range provided by our underwriters of $15.00 per share is a reasonable estimate of the fair value of our common stock as of September 15, 2012. The change in the fair value of our common stock to the midpoint of the price range for this offering was not significant, and no equity awards were granted by the board of directors after July 27, 2012.

Stock-based compensation expense included in operating results during the years ended December 31, 2009, 2010, and 2011 and the six months ended June 30, 2011 and 2012 was included in cost and expenses as follows:

The intrinsic value of all outstanding options as of June 30, 2012 was $36.5 million based on the estimated fair value for our common stock of $15.00 per share, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus. As of June 30, 2012, we had $3.9 million of unrecognized stock-based compensation expense, net of estimated forfeitures, that is expected to be recognized over a weighted average period of 2.9 years. In future periods, our stock-based compensation expense is expected to increase as a result of our existing, unrecognized stock-based compensation, to be recognized as these awards vest and as we issue additional stock-based awards to attract and retain employees.

We account for our income taxes in accordance with the liability method. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for operating losses and tax credit carryforwards. Management must make assumptions, judgments, and estimates to determine our current provision for income taxes and also our deferred tax assets and liabilities as well as any valuation allowance to be recorded against a deferred tax asset.

Our assumptions, judgments, and estimates relative to the current provision for income taxes take into account current tax laws, our interpretation of current tax laws, and possible outcomes of current and future audits conducted by domestic tax authorities. We have established reserves for income taxes to address potential exposures involving tax positions that could be challenged by tax authorities. Although we believe our assumptions, judgments, and estimates are reasonable, changes in tax laws or our interpretation of tax laws, and the resolution of potential tax audits could significantly impact the amounts provided for income taxes in our financial statements.

Our assumptions, judgments, and estimates relative to the value of a deferred tax asset take into account predictions of the amount and category of future taxable income, such as income from operations or capital gains income. Actual operating results and the underlying amount and category of income in future years could render our current assumptions, judgments and, estimates of recoverable net deferred taxes inaccurate. Any of the assumptions, judgments, and estimates mentioned above could cause our actual income tax obligations to differ from our estimates, thus materially impacting our financial position and results of operations.

Since inception, we have incurred operating losses, and accordingly, we have not recorded significant provisions for income taxes for any of the periods presented. We do not expect any significant changes until we are no longer incurring losses.

We have provided a full valuation allowance for net operating losses, credits, and other deferred tax assets for the state of California and the United States. A valuation allowance is provided when based upon the available evidence, and when management concludes that it is more likely than not that some portion of the deferred tax assets will not be realized. We maintained a full valuation allowance as of December 31, 2011 due to the uncertainty of realizing future tax benefits from its net operating loss carryforwards and other deferred tax assets. As of December 31, 2011, we had federal and state net operating loss carry forwards of $29.7 million and $24.9 million. The federal net operating loss carry forward will expire at various dates beginning in the year ending December 31, 2025, if not utilized. If not used, the state net operating loss carry forward will expire at various dates beginning in the year ending December 31, 2015.

Under the Jumpstart Our Business Startups Act, or JOBS Act, we meet the definition of an “emerging growth company.” We have irrevocably elected to opt out of the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act.

In January 2010, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, No. 2010-06, Improving Disclosures about Fair Value Measurements (Topic 820)—Fair Value Measurements and Disclosures, which requires additional disclosures about the different classes of assets and liabilities measured at fair value, the valuation techniques and inputs used, and the activity in Level III fair value measurements. This guidance was effective for interim and annual reporting periods beginning after December 15, 2009, except for certain Level III activity disclosure requirements that became effective for reporting periods beginning after December 15, 2010. Accordingly, we adopted this new guidance beginning January 1, 2010, except for the additional Level III requirements, which were adopted beginning January 1, 2011. Level III assets and liabilities are those whose fair value inputs are unobservable and reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. The adoption of this guidance required additional disclosures but did not have a material impact on our results of operations or financial position.

In May 2011, the FASB issued ASU No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards, or IFRS. This pronouncement was issued to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and IFRS. ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for Level III fair value measurements. This pronouncement is effective for reporting periods beginning on or after December 15, 2011, with early adoption prohibited. We adopted this standard on January 1, 2012 as reflected in Note 3 of our audited financial statements included elsewhere in this prospectus.

In June 2011, the FASB issued ASU No. 2011-05, Presentation of Comprehensive Income, which requires an entity to present total comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements and eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. We early adopted this guidance on January 1, 2012, retrospective. During the years ended December 31, 2009, 2010, 2011 and the six months ended June 30, 2011 and 2012, we did not have any other comprehensive income and, therefore, the net loss and comprehensive loss was the same for all periods presented.

Our online marketplace is experiencing rapid growth. Monthly unique visitors to our marketplace increased from 5.0 million in the six months ended June 30, 2009 to 22.0 million in the six months ended June 30, 2012, and our subscribers increased from 2,398 as of June 30, 2009 to 21,544 as of June 30, 2012. We generate revenue primarily from sales of subscription products to real estate professionals. We also generate revenue from display advertising sold to leading real estate and consumer brand advertisers seeking to reach our attractive audience. For the years ended December 31, 2009, 2010, and 2011, and the six months ended June 30, 2012, we generated revenue of $10.3 million, $19.8 million, $38.5 million and $29.0 million, respectively. During the same period, we had net losses of $7.0 million, $3.8 million, $6.2 million, and $7.6 million, respectively.

The residential real estate industry, which we estimate accounts for more than a trillion dollars in annual spending in the United States, is undergoing a profound transformation. Technology is changing the way that consumers search for homes, and the way in which real estate professionals attract clients and build their businesses. In addition, the recent unprecedented downturn in the housing market is causing real estate professionals to seek more effective ways to market themselves and achieve a greater return on their marketing investment. These trends present significant opportunities to capitalize on shifts in behavior.

Housing decisions are among the most important in people’s lives as a home purchase is one of the largest investments consumers will ever make. As a result, consumers devote tremendous time and energy to researching their decisions, seeking information on home prices, home features, schools, crime, neighborhood amenities, financing options, home values, real estate professionals, and numerous other factors as they evaluate prospective homes. The insights learned from this research inform their decisions of where to live, how much to pay, and who to hire as an agent.

Historically, consumers lacked readily available access to detailed and comprehensive information essential to making housing decisions, relying instead on disparate sources of information such as real estate professionals, local newspapers, and word of mouth. Over time, more information has become available online and, as a result, the Internet has become a primary source of research for housing decisions. According to a November 2011 survey by the National Association of Realtors, 88% of home buyers used the Internet to research homes. Additionally, the use of mobile devices for home searches has become more prevalent. According to a 2012 survey by The Real Estate Book, 52% of respondents reported using a mobile device to look for homes, with 85% of non-users stating that they would consider using a mobile device for their next search.

Real estate professionals are not alone in recognizing the growing importance and tremendous value of online targeted marketing. Online real estate marketplaces provide an efficient channel for the broader real estate ecosystem to more effectively reach potential customers. Landlords with properties for rent, mortgage companies, and home service providers are also finding targeted marketplaces fertile ground for leads and are increasingly advertising on these sites.

As technology drives the home search process online, consumers, real estate professionals, and advertisers face distinct challenges.

Real estate professionals face challenges in attracting clients and growing their businesses, including:

Advertisers face challenges as they seek to connect with consumers searching for homes. Advertisers historically lacked the ability to efficiently reach a relevant consumer audience and target specific subsets of that audience, based on demographics and other factors. Additionally, advertisers need to maximize the return on their advertising budget in a measurable and data-driven way.

We believe that there are significant opportunities to address the challenges faced by consumers, real estate professionals, and advertisers. Borrell Associates estimated in an August 2012 industry paper that $23.7 billion would be spent in 2012 on real estate-related marketing in the United States. According to a November 2011 survey by the National Association of Realtors, 88% of home buyers used the Internet to research homes. However, according to the Borrell Associates report, only 55% of the real estate marketing dollars in the United States were projected to be spent online in 2012. We believe that there is a disconnect between where marketing dollars are spent and where consumers research homes. Therefore, we expect that real estate-related marketing spend will continue to migrate online from traditional channels.

We are redefining the home search experience for consumers and changing the way that real estate professionals build their businesses. We believe we deliver the best home search experience by combining our superior user interface with our comprehensive database of real estate properties, local insights, and user-generated content. We offer free and subscription products that provide real estate professionals with access to transaction-ready consumers and help them enhance their online presence. In the six months ended June 30, 2012, we had 22.0 million monthly unique visitors. As of June 30, 2012, we had more than 360,000 active real estate professionals in our marketplace, 21,544 of whom were paying subscribers.

Our marketplace provides the following key benefits for consumers, real estate professionals, and advertisers:

Large, continually refreshed, searchable database of homes for sale and rent. We provide consumers with access to a large, continually refreshed, and searchable database of properties. We enable consumers to customize their searches with property-specific filters to obtain up-to-date listings that are rich with property facts, price, and sale data. We believe the scope and quality of the information contained in our database and the ease of use of our solution empowers consumers to more effectively find the right home.

Trusted insights, social recommendations, and proprietary analytics that provide local context. We provide consumers with local insights, critical to a successful home search, not available elsewhere on an easy to use and comprehensive basis. These insights include information about schools, crime, neighborhood amenities, and real estate professionals. We provide this broad range of local insights and rich features on our marketplace through our proprietary Trulia Voices forum and via our integration with Facebook. We also provide proprietary analytics on home valuation, including comparative historical price trends down to the neighborhood level. We believe the relevance of our data, paired with socially-informed insights, enables our consumers to better inform themselves on where to live.

Anytime and anywhere access. Our marketplace is accessible anytime and anywhere on the web and on major mobile platforms. To meet the needs of consumers who are increasingly conducting their real estate research on mobile devices, including while touring neighborhoods and visiting homes, we offer mobile applications that are currently available for use on the iPhone, iPad, Android phones, Android tablets, and Kindle Fire. Since the introduction of our first mobile application in 2008, mobile use of our marketplace has grown rapidly.

Broad reach to transaction-ready consumers. We provide real estate professionals the ability to connect with our large audience of transaction-ready consumers on the web and through our mobile applications. We believe that a large portion of consumers using Trulia do not use other real estate websites, and that this enables real estate professionals on Trulia to effectively identify and market themselves to consumers that they cannot find anywhere else.

Products that boost presence and deliver high-quality leads. We offer a suite of differentiated products that provides real estate professionals with access to transaction-ready consumers, delivers high-quality leads and helps close deals. Our free products enable real estate professionals to build their personal brand by creating an online profile, contributing content to our marketplace, leveraging social media for endorsements, and establishing their presence through mobile features such as “check-ins.” Our subscription products enable real estate professionals to boost their visibility, promote their listings in search results, and generate more high-quality leads from our large audience of transaction-ready consumers.

Anytime and anywhere access to critical information and tools. We offer mobile applications designed specifically for real estate professionals to take their business on the go. Using our mobile applications, real estate professionals can access critical information that they need to conduct their business, including listings details, contacts, driving directions, and local information about neighborhoods. They also receive real-time notifications of new leads so that they can respond quickly and secure new clients. Our latest mobile product, Trulia Mobile Ads, allows professionals to reach a local, transaction-ready audience by advertising on our mobile applications for consumers.

Significant return on investment. We believe that our subscription products deliver a high return on investment to real estate professionals. Unlike traditional marketing channels, we provide tools to track leads and manage performance, enabling real estate professionals to measure and quantify the value of our products.

Attractive audience. We believe our audience composition is highly attractive to consumer brand advertisers. A substantial portion of our audience is college educated, has a household income above $75,000, or is in the 25 to 54 age group. U.S. consumers with these characteristics tend to spend more of their annual income on home maintenance, insurance, household furnishings, apparel and services, and entertainment than the average consumer, according to the Bureau of Labor Statistics 2010 Consumer Expenditure Survey, which makes our audience attractive for consumer brand advertisers.

Display advertising products that efficiently reach target consumers. We enable our advertisers to reach the specific segments of our audience that are attractive to them. Advertisers benefit from improved reach, impact, relevancy, and measurement of their marketing campaigns in our marketplace.

We are one of the leading online real estate marketplaces and we provide consumers with powerful tools and unique content that together deliver valuable insights into homes, neighborhoods, and real estate professionals. Consumers require information from local sources in addition to detailed property data to gain a comprehensive view of a home and neighborhood. We supplement our extensive database of over 110 million properties in the U.S. with information on schools, crime, and neighborhood amenities, and enable social recommendations. For example, our crime heat maps provide consumers with a view into neighborhood safety and our Facebook integration gives consumers recommendations on real estate professionals from people in their social network. Through our proprietary Trulia Voices forum, we also provide consumers with local content from our community of contributors, including consumers, local enthusiasts, and real estate professionals. With over 5 million unique user contributions, we believe we have the largest collection of user-generated content on homes, neighborhoods, and real estate professionals.

We believe we have the best products in the industry for consumers and real estate professionals. We invest significant resources into technology development and product design to create a superior user interface that provides compelling features and rich functionality for our users. In addition, we offer unique search capabilities that allow users to search for homes in more intuitive ways, including by school districts, and by designating customizable areas on an interactive map. We also aggregate and integrate information from multiple sources and display it in an easy-to-consume manner that provides a more comprehensive view of a home or neighborhood. Our agent tools provide an easy way to manage their listings and interactions with leads and clients. We believe our products and user experience are a primary reason why, with limited marketing expenditures, we have been able to attract a large audience.

We believe we have become the online destination of choice for transaction-ready consumers in the residential real estate market. Our website and mobile applications attracted 22.0 million monthly unique visitors in the six months ended June 30, 2012, and based on data from comScore, a significant portion of our visitors do not visit our primary competitors’ websites. For instance, according to monthly data reported by comScore, during 2011, an average of 64% of our audience did not visit Zillow.com, and during the six months ended June 30, 2012, an average of 56% of our audience did not visit Zillow.com. In addition, based on data from comScore, our audience is more engaged with our marketplace than users of our primary competitor’s website, Zillow.com. Based on monthly data reported by comScore, during the 18 month period ended June 30, 2012, each unique visitor on average spent 14% more time per month on our marketplace than on Zillow.com’s marketplace, and viewed 44% more pages on our marketplace than on Zillow.com’s marketplace. We also believe that our audience is highly motivated and ready to purchase homes, as supported by our surveys in which 76% of respondents contacting real estate professionals on our marketplace indicated that they are planning to move in the next six months, and in which almost half stated that they are pre-qualified for a mortgage. We believe the transaction-ready nature of our audience results in better qualified leads for real estate professionals and an attractive audience for advertisers.

We believe we are one of the few companies that is monetizing its mobile products at a higher rate than web products. Since we launched our subscription product for mobile devices in May 2012, we have sold this product at prices that yield a higher average monthly revenue per subscriber than our subscription products that are not focused on mobile devices. In addition, our users are more likely to contact real estate professionals through our mobile applications than our website.

We believe our subscription products provide compelling value and a high return on investment for real estate professionals. On average, paying subscribers receive more than five times the number of monthly leads as real estate professionals who only use our free products. Unlike traditional marketing channels, our online marketplace allows real estate professionals to track, manage, and communicate with prospects, helping to measure and quantify the value we create. Based on our attractive monthly pricing, the likelihood that our users will complete real estate transactions, and the large commissions generated by real estate professionals on transactions, we believe our products generate significant return on investment for our subscribers. The value our real estate professionals receive from our marketplace is validated by our high subscriber growth and our increasing average monthly revenue per subscriber.

We benefit from a self-reinforcing network effect that helps build our brand, drives user engagement in our marketplace, and attracts more users to our website and mobile applications. As consumers engage in our marketplace, they contribute content by reviewing homes and neighborhoods, writing agent recommendations, and posting questions to our community of local enthusiasts and real estate professionals. Based on our internal records, we have determined that consumers who interact with our user-generated content view more pages per visit and spend more time per visit on our marketplace, and ultimately generate more leads for our subscribers. The opportunity to interact with, and market to, these consumers attracts more real estate professionals, who engage with consumers by sharing local knowledge and contributing more content to our forum. The growing breadth and quality of user-generated content contributed by both consumers and real estate professionals builds our brand as a differentiated resource and, we believe, attracts more users to our website and mobile applications.

We have invested heavily over many years to build a robust data and analytics platform. We employ proprietary advanced analytics and heuristics capabilities to aggregate, filter, and analyze large amounts of data from disparate sources that we have cultivated over the years, including MLS and broker listing feeds, local demographic sources, and government archives. Our expertise in handling large amounts of externally-sourced data and combining it with user activity data collected from our marketplace allows us to improve the user experience by developing innovative new tools and new functionality. Additionally, we use this rich data to drive strategic business decisions and to publish insightful analysis on trends in local housing markets and macroeconomic trends in residential real estate. For example, we recently added the ability for real estate professionals to learn the geographic origin of search queries for homes in their market. We believe that our robust data and analytics platform gives us a competitive advantage in developing a superior experience for consumers and real estate professionals and raises awareness of our products in the real estate industry.

Our goal is to build the leading online real estate marketplace. We intend to focus on the following key strategies in pursuit of our goal:

We intend to grow our large, transaction-ready audience by continuing to offer superior products for consumers. We plan to continuously enhance and refresh our database of homes, to partner with third parties to add new and relevant local content, and to encourage our users to contribute useful content. We also plan to develop new features, tools, and products that deepen our users’ engagement with our website and mobile applications, and to promote and foster interaction in our vibrant user community.

We intend to further penetrate the large base of more than 2.8 million real estate professionals in the United States. We plan to attract more real estate professionals to our marketplace by communicating the value proposition of our free and subscription products and continuing to offer access to high-quality leads from our large and growing audience of transaction-ready consumers. We also intend to enhance and increase the ways in which real estate professionals can market themselves and communicate with prospective clients on our site, and to create additional value-added products to help professionals more effectively manage their leads, documents, and other key elements of their business.

We plan to increase our revenue by selling more subscription and advertising products and by optimizing our pricing. We seek to attract more real estate professionals to our marketplace, convert more of our free real estate professional users to paying subscribers, and up-sell existing subscribers. We also intend to optimize the pricing of our products. Additionally, we plan to continue growing our advertising business by seeking larger and longer-term commitments from advertisers, diversifying our client base into different advertising verticals, and by adding additional media sales personnel to market to advertisers looking to target our large, attractive audience.

We have built a leading real estate and consumer brand with limited marketing spend to date. We plan to continue to grow our brand by providing our users with superior and innovative products. We plan to build our brand as the most trusted source of real estate information with concerted public relations efforts that use our data and analytics platform to educate consumers and deliver relevant insights into the real estate market.

We plan to pursue opportunities in a number of large adjacent markets, such as rentals, mortgages, home improvement, and agent tools, and to expand our business internationally. We believe that given our attractive audience, leading brand, and powerful technology platform, we are well positioned to capitalize on the large opportunities that these adjacent markets offer.

Management of data is a critical component of our solution. We manage over one terabyte of data on a daily basis. We organize data as listings data, local information, and user-generated content:

We refresh and supplement our listings database of over 110 million properties and for sale and for rent listings with data we receive from thousands of feeds on a daily basis. We receive feeds covering millions of new and existing for sale and for rent listings every day from MLSs, real estate brokerages, real estate agents, real estate listings aggregators, and other third parties. We also obtain detailed ownership and property data from vendors who collect and digitize information from public county records.

We process this wealth of data through our proprietary algorithms and heuristic data validation engine to sort, augment, and select the most up-to-date and accurate data to display. As a next step, we apply our search logic to the data, and overlay additional local information on schools, crime, neighborhood amenities, home values, and other community information. The final product is a complete profile of a property or listing with property facts, price data, local information, and agent contact information, which we publish in our marketplace in an intuitive and engaging user experience.

We inform consumers on what it is like to live in a neighborhood by delivering insights on schools, crime, neighborhood amenities, home values, and other community information.

Additionally, we have an agreement with Google to use its basic maps, over which we integrate our proprietary insights.

The user-generated data in our marketplace is organized under the Advice section of our website by type of content, questions and answers, blogs, real estate guides, and along topics relevant to our audience such as local information, tips on home buying and selling, and observed market trends. We also allow real estate professionals to publish their own profile and receive recommendations from their clients under the Find a Pro section of our website.

The content in our marketplace is generated by our vibrant community of users. Users can vote on the quality of content using our “thumbs up” or “thumbs down” icons and can follow the voting results. Additionally, users can “flag” inappropriate content on our site, which is escalated to our Trulia community team whose enforcement actions follow the terms and conditions for user-submitted content as published on our website.

Our products for consumers focus on helping them find the right home. Our consumer products are offered for free and provide a robust set of tools for evaluating where to live.

We maintain one of the largest searchable databases of homes for sale and rent in the United States. Our database includes more than 110 million properties with 4.5 million listings of homes for sale and rent. We provide users with the ability to search our database along a variety of parameters as described below:

Our users can customize their search along as few or many features as they prefer and by keyword search of specific property attributes. From our search results, users have access to the detailed data on each home in our database, photos of the home, and the for sale or for rent listing information.

Additionally, we enhance our users’ experience by giving them the choice to display their search results in listings or map formats. The map format provides the added functionality of polygonal search, which enables users to delineate the precise area of their searches. We offer products that further enhance our users’ experience with visually impactful maps, graphics, and photos of homes and neighborhood characteristics.

Trulia Estimate is our estimate of an off-market property’s value based on our proprietary analysis of relevant home data such as recent sales of similar homes and property facts. This search function allows users to conduct a precise search by street address to find our estimate of the value of that home. Additionally, home owners may claim their home in our database and edit their home’s specific facts and details so that our proprietary system can revise its estimated value.

We provide users with rich insights and content that are critical to a successful home search and that cannot be discovered through home listings data alone. We deliver these insights through the following products:

Our products are accessible anytime and anywhere online and on mobile devices. We provide the following differentiated Trulia mobile applications for consumers on several major mobile platforms and devices:

We offer real estate professionals a set of subscription and free products to promote themselves and their listings online and to connect with consumers searching for homes. We generally sell our subscription products on a one, three, six, or twelve-month basis, and therefore, our subscribers’ commitment periods may be short-term in nature. We also offer our subscription products at different price points. In addition to the pricing options, our subscribers can choose among different features and packages with each of our subscription products, as described below.

We sell display media advertising on a cost-per-impression and cost-per-click basis to national advertisers seeking to reach our large and attractive audience. We display their advertisements on our home page and on individual web pages through graphical displays and text links, and help these customers optimize their advertisements’ effectiveness through our robust targeting capabilities. We also offer display media advertising on our mobile website that is optimized for mobile device web browsers.

Product development and innovation are core pillars of our engineering culture that aims to delight our users and customers with our products. We provide our web and mobile products using a combination of in-house and third-party technology and products.

Big data and proprietary algorithms. We have developed our technology platform to handle data at large scale. On a daily basis, we process several million home listings from thousands of data feeds through our proprietary algorithms and heuristic data validation engine to sort, augment, and select the most up-to-date and accurate data to display.

Infrastructure. We host our platform from two locations. The primary location where we host our production environment, is within a shared data center environment in Santa Clara, California. We use a second hosted facility, located in Oakland, California, for production service backup and for our development environment. Our website and mobile applications are designed to have high availability, from the Internet connectivity providers we choose, to the servers, databases, and networking hardware that we deploy. We design our systems such that the failure of any individual component is not expected to affect the overall availability of our platform. We also leverage content delivery networks and use other third-party cloud computing services, including map-related and ad serving services, to ensure fast and local access to content. We employ a host of encryption, antivirus, firewall, monitoring, and patch-management technology to protect and maintain our systems.

Innovation. In addition to our new product development efforts, we encourage technological advances by directing a portion of our engineering team’s time towards organized innovation days. Each quarter, our product managers and engineers share ideas and experiments and recruit their peers to join their projects to bring a new concept to life. As progress is shared with the larger group, these new ideas receive additional input and product planning and are frequently the basis of new products and features we offer.

Agile methodology and quality focus. Our software development methodology is agile and promotes teamwork, collaboration, and process adaptability throughout the life cycle of a development project. We believe this methodology yields robust, high quality, efficient, and nimble software development. We also invest heavily in the quality of our technology with robust testing at each stage in our development process.

In June 2012, we entered into a Platform Services Agreement with Move Sales, Inc., or ListHub, which provides us with a substantial portion of the unique listings in our marketplace. This agreement supersedes our prior agreement with ListHub for the provision by ListHub of listings to us. Under the terms of this agreement, ListHub grants to us a nonexclusive license to display listings on our platform and use these listings for the purpose of providing real estate professionals with information relating to lead generation management and advertising products. This agreement contains a 48-month term and renews automatically for additional one year terms unless canceled upon the provision of 90 days prior notice by either party. This agreement is not cancelable by ListHub except in the case of material uncured breach by us or our filing for bankruptcy, insolvency or assignment for the benefit of creditors, or if a receiver is appointed on our behalf.

We maintain our technology infrastructure at a facility in Santa Clara, California maintained by Equinix Operating Company, Inc., or Equinix. Equinix provides data center space to us under the terms of a master service agreement. This agreement terminates on the earlier of the date that it is terminated by either party or the last order made under the agreement terminates or expires. This agreement is not cancelable by Equinix except in the case of material uncured breach by us, the suspension by Equinix three or more times during any 12 month period of its services pursuant to the terms of this agreement, our liquidation, cessation to do business or insolvency, or the condemnation of the physical space subject to this agreement.

Our principal marketing strategy has been to develop a superior user experience that will drive audience growth and brand recognition. We have not historically spent significantly on marketing programs, but have focused on organic and viral growth driven by our user base. As our consumer audience has grown, real estate professionals have followed consumers to Trulia. We have also grown our brand among real estate professionals and the real estate industry through tradeshow participation, social engagement, and ongoing education via webinars, newsletters, and word of mouth.

In addition, our media outreach programs have been major drivers in growing our brand. We publish a series of blogs and actively use social media to share and spread content on a variety of topics to elevate our brand, including:

These reports are used by, and our Chief Economist is quoted regularly in, major news outlets, including The Wall Street Journal, Bloomberg, The New York Times, Time Magazine, and U.S. News & World Report.

We also cultivate our brand awareness through social media channels, such as Facebook and Twitter.

The majority of our real estate professional subscribers are agents. As of June 30, 2012, we had more than 360,000 active real estate professionals in our marketplace, 21,544 of whom were paying subscribers. A key focus of our sales and marketing activities has been to further penetrate the large base of more than 2.8 million real estate professionals in the United States. If we are unable to increase the number of total subscribers in our marketplace, our revenue may not grow and our operating results could suffer.

Our advertising solutions are purchased by a diverse cross-section of brand advertisers that operate within the real estate ecosystem, and those that seek to reach our highly educated and affluent audience. In each of the years ended December 31, 2010 and 2011, the ten largest advertising partners for the respective period accounted for more than 50% of our media revenue. For the six months ended June 30, 2012, the ten largest advertising partners in that period accounted for more than 60% of our media revenue.

We have dedicated sales teams that support our marketplace business and our display advertising business.

For our marketplace business, the majority of our sales are made by our inside sales team that sells our subscription products to real estate professionals. Our inside sales team is located in our San Francisco and Denver offices and attracts new subscribers through a combination of outbound calling and inbound customer requests generated from our website and marketing activities. We also have a field sales team that sells our marketplace products at larger deal sizes to real estate brokers, franchisors, and builders.

For our display advertising business, we maintain a field sales team based in New York, to specifically target large advertising customers in the real estate and related content categories, such as insurance companies, mortgage providers, and home improvement companies, as well as other brand advertisers that seek to reach our audience. Our field sales team develops direct relationships with these advertisers and the agencies that serve them.

We place a high value on providing quality support to our users, marketplace subscribers, and advertisers. Our customer support team, based in San Francisco and Denver, responds to commercial and technical questions from our users and advertisers.

The markets in which we operate are highly competitive and fragmented. Consumers research homes through a variety of sources. Similarly, real estate professionals use a variety of marketing channels to promote themselves and find clients. Consequently, we face competition from a variety of direct and indirect channels, and we believe we compete favorably.

We compete to attract consumers to our website and mobile applications primarily on the basis of the breadth and quality of listings; user experience; the breadth, depth, and relevance of the insights on homes, neighborhoods, and real estate professionals; brand and reputation; and the quality of mobile products.

We compete for a share of real estate professionals’ overall marketing spend with traditional, offline media, and other online marketing channels. We compete primarily on the basis of the size and attractiveness of the consumer audience; quality and measurability of leads; perceived return on investment; effectiveness of marketing and workflow tools; and quality of mobile products.

We face competition to attract advertisers to market their products on our website. The basis of competition includes size, demographics, and overall attractiveness of an audience; pricing; and the ability to target desired audience segments.

We protect our intellectual property through a combination of trademarks, domain names, copyrights, trade secrets, and patents, as well as contractual provisions and restrictions on access to our proprietary technology.

We registered “Trulia” as a trademark in the United States and several other jurisdictions. We also have filed other trademark applications in the United States and certain other jurisdictions, and will pursue additional trademark registrations to the extent we believe it would be beneficial and cost effective.

We have two patent applications pending in the United States, which seek to cover proprietary techniques relevant to our products. We intend to pursue additional patent protection to the extent we believe it would be beneficial and cost effective.

We are the registered holder of a variety of domestic and international domain names that include “Trulia” and similar variations.

In addition to the protection provided by our intellectual property rights, we enter into confidentiality and proprietary rights agreements with our employees, consultants, contractors, and business partners. Our employees and contractors are also subject to invention assignment agreements. We further control the use of our proprietary technology and intellectual property through provisions in both our general and product-specific terms of use on our website.

As of June 30, 2012, we had 462 full-time employees, with 118 in technology, 303 in sales, marketing, and customer support, and 41 in general and administrative functions. We had 267 full-time employees in our San Francisco headquarters, 165 in our Denver location, 16 in our New York office, and 14 of our employees work remotely. None of our employees is represented by a labor union with respect to his or her employment with us.

We believe that our team and company culture have been among the keys to our success, allowing us to attract a talented group of employees, create a dynamic work environment, and continuously deliver innovation in a highly competitive market. As a team, we embrace the following I.M.P.A.C.T. principles:

In May 2010, we entered into a lease effective through May 2014 for approximately 32,000 square feet of office space that houses our principal offices in San Francisco. In March 2012, we entered into a lease effective through March 2013 for approximately 9,500 square feet of office space that houses our additional office space in San Francisco. We lease additional office space in Denver and New York. We believe our facilities are sufficient for our current needs.

From time to time, we may be subject to legal proceedings and claims in the ordinary course of business. We have received, and may in the future continue to receive, claims from third parties asserting, among other things, infringement of their intellectual property rights.

In July 2011, CIVIX-DDI LLC, or CIVIX, a non-practicing entity, filed a complaint against us in the U.S. District Court for the Eastern District of Virginia alleging, among other things, infringement of two patents by the products we provide through our website for searching and locating real estate. In September 2011, we entered into a license agreement with CIVIX to purchase a license for these patents for $550,000 and, as a result, the corresponding litigation was dismissed. Pursuant to this agreement, we agreed to pay a guaranteed amount of $550,000 to CIVIX, of which we have already paid $450,000 and the remaining $100,000 will be paid in September 2012. We also agreed to pay another $350,000 that is contingent on the completion of an offering.

Future litigation may be necessary to defend ourselves, our partners and our customers by determining the scope, enforceability, and validity of third-party proprietary rights or to establish our proprietary rights. The results of any current or future litigation cannot be predicted with certainty, and regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors.

Each executive officer serves at the discretion of our board of directors and holds office until his or her successor is duly elected and qualified or until his or her earlier resignation or removal. There are no family relationships among any of our directors or executive officers.

Our board of directors has adopted a code of business conduct and ethics that applies to all of our employees, officers, and directors, including our Chief Executive Officer, Chief Financial Officer, and other executive and senior financial officers.

Our business and affairs are managed under the direction of our board of directors. The number of directors will be fixed by our board of directors, subject to the terms of our amended and restated certificate of incorporation and amended and restated bylaws that will become effective immediately prior to the completion of this offering. Our board of directors consists of six directors, four of whom qualify as “independent” under New York Stock Exchange listing standards.

In accordance with our amended and restated certificate of incorporation and our amended and restated bylaws, immediately after the completion of this offering our board of directors will be divided into three classes with staggered three-year terms. Only one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms. Our directors will be divided among the three classes as follows:

Any increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors.

This classification of our board of directors may have the effect of delaying or preventing changes in control of our company.

Our board of directors has undertaken a review of the independence of each director. Based on information provided by each director concerning his or her background, employment, and affiliations, our board of directors has determined that Ms. Gouw Ranzetta and Messrs. Bardman, Moles, and Waldorf do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is “independent” as that term is defined under the applicable rules and regulations of the SEC and the listing standards of the New York Stock Exchange. In making these determinations, our board of directors considered the current and prior relationships that each non-employee director has with our company and all other facts and circumstances our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director, and the transactions involving them described in the section titled “Certain Relationships and Related Party Transactions.”

Our board of directors has established an audit committee, a compensation committee, and a nominating and governance committee. The composition and responsibilities of each of the committees of our board of directors is described below. Members will serve on these committees until their resignation or until as otherwise determined by our board of directors.

None of our executive officers currently serves, or in the past year has served, as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving on our board of directors or compensation committee.

In 2011, none of our non-employee directors received any cash, equity, or other compensation for their services as directors or as members of any board committee. As of December 31, 2011, none of our non-employee directors had unvested shares of common stock that would have accelerated if their services had been terminated in connection with a change in control.

In January 2012, we entered into a letter agreement with Gregory Waldorf confirming his agreement to serve as the lead independent director of our board of directors. Pursuant to the letter agreement, in February 2012, our board of directors granted to Mr. Waldorf a stock option to purchase 24,500 shares of common stock at a price per share of $6.81, which was the fair market value of our common stock on the date of grant. The stock option granted to Mr. Waldorf vests monthly over a 12-month period, and has a vesting commencement date of July 1, 2011. As such, a majority of shares subject to the stock option were vested on the date of grant, which was in recognition of Mr. Waldorf’s significant contributions and service to us as a director and advisor. In addition, pursuant to the letter agreement, we also paid Mr. Waldorf a cash bonus of $25,000 in April 2012, and agreed to reimburse him for reasonable travel and incidental expenses that we approve.

Directors who are also our employees receive no additional compensation for their service as a director. During 2011, Messrs. Flint and Inkinen were employees. See the section titled “Executive Compensation” for more information about their compensation.

Following the completion of this offering, we intend to implement a formal policy pursuant to which our non-employee directors would be eligible to receive equity awards and annual cash retainers as compensation for service on our board of directors and committees of our board of directors.

The following discussion and analysis of the compensation arrangements of our named executive officers should be read together with the compensation tables and related disclosures set forth below. This discussion contains forward-looking statements that are based on our current plans, considerations, expectations, and determinations regarding future compensation programs. The actual amount and form of compensation and the compensation policies and practices that we adopt in the future may differ materially from currently planned programs as summarized in this discussion.

The compensation provided to our named executive officers for 2011 is detailed in the 2011 Summary Compensation Table and accompanying footnotes and narrative that follows this section. This section explains our executive compensation philosophy and objectives, our compensation-setting process, and the elements of our compensation program.

In March 2012, Mr. Inkinen’s employment with us ended, but Mr. Inkinen continues to serve as one of our directors. Mr. Inkinen served as our principal financial officer in 2011 prior to our hiring of Mr. Aggarwal.

Our executive compensation philosophy is to provide a compensation program that attracts and retains our executive officers, including our named executive officers, and to motivate them to pursue our corporate objectives while encouraging the creation of long-term value for our stockholders. We strive to provide compensation packages to our executive officers that are competitive, reward achievement of our business objectives, and align executive and stockholder interests through equity ownership.

Our executive compensation program is designed to achieve the following principal objectives:

The initial compensation arrangements with our executive officers, including the named executive officers, have been determined in negotiations with each individual executive when such executive joined us. Typically, the board of directors or our CEO has been responsible for negotiating these arrangements.

With respect to continuing executive compensation arrangements, our board of directors has been responsible for overseeing, determining, and approving the compensation of our CEO and our former President, and has been responsible for overseeing the compensation of our other executive officers on an informal basis. With respect to the compensation of our named executive officers other than our CEO, our board of directors consults with our CEO and has typically informally approved his recommendations because of his closer nexus to his direct reports. Historically, our board of directors has overseen our 2005 Stock Incentive Plan, or the 2005 Plan, and awards thereunder.

Typically, in the first quarter of each year, our board of directors would review the compensation of our CEO. At that time, our board of directors would also evaluate the performance of the company and the CEO’s contributions thereto to determine whether to pay him cash bonuses for the previous year and, if so, the amount of any such bonuses.

In February 2012, we established a compensation committee of our board of directors, or the Committee, that has assumed responsibility for overseeing our executive compensation program and will approve the compensation of our CEO and our executive officers. The Committee determined incentive compensation earned by our named executive officers for the 2011 performance period. Going forward, the Committee will be responsible for annually reviewing and approving compensatory arrangements for our named executive officers and will act as administrator of our equity compensation plans. See the summary description of the Committee’s composition and charter in the section titled “Management—Committees of the Board of Directors—Compensation Committee.”

In prior years, our CEO has typically sought the approval of our board of directors on an informal basis regarding the compensation for our other named executive officers. While our board of directors had final authority with respect to compensation decisions for our executive officers, our board of directors typically deferred to the recommendations of our CEO with respect to our other named executive officers because our CEO had a better understanding of the performance of his direct reports. With respect to his role in our executive compensation process, our CEO quarterly reviewed the performance of the other named executive officers and consulted with our board of directors on an informal basis on his conclusions and recommendations as to their compensation, including base salary adjustments and cash bonus payouts. Our CEO advised our board of directors on recommended stock option awards to the other named executive officers, which were subject to formal approval by our board of directors.

The Committee is authorized to retain the services of one or more executive compensation advisors, as it sees fit, in connection with the establishment of our compensation programs and related policies.

In October 2011, we retained Radford, a national compensation consultant, to provide general market data and recommendations on non-executive compensation and expanded this engagement to include executive compensation and compensation for our board of directors. No guidance provided by Radford was used with respect to any compensation decisions for 2011. Prior to engaging Radford, our board of directors had not retained a compensation consultant for any services or recommendations related to executive compensation decisions.

In May 2012, the Committee retained Radford to provide it with information, recommendations and other advice relating to executive compensation on an ongoing basis. Accordingly, Radford now serves at the discretion of the Committee. The Committee has directed Radford to develop one or more groups of peer companies to help us determine the appropriate level of overall compensation for our executive officers, as well as assess each separate element of compensation, with a goal of more formally ensuring that the compensation we offer to our executive officers is competitive and fair.

Following the completion of this offering, we expect that the specific direction, emphasis and components of our executive compensation program will continue to evolve as will our process for establishing executive compensation. In the future, the Committee may continue to retain Radford or another compensation consultant to advise us regarding our executive compensation program to ensure that it remains properly aligned with our ongoing business strategy and that the pay mix and levels are competitive with current market practices.

Our compensation program for our named executive officers reflects our stage of development as a private company. As a private company, we have emphasized the use of equity in the form of stock options to incentivize our named executive officers to focus on our growth and create sustainable long-term stockholder value. Our founders were initially incentivized through restricted stock. We believe that equity awards offer our named executive officers a valuable long-term incentive that aligns their interests with the interests of our stockholders.

We also offer cash compensation to our named executive officers in the form of a base salary and an annual cash incentive award opportunity at levels that we believe, based on the experience and knowledge of our board of directors and our management team, are competitive for our stage of development and industry. Our annual cash incentive award opportunities generally focus on the achievement of specific near-term financial and strategic objectives and individual key performance objectives that will further our longer-term growth objectives. In addition, in order to attract and induce potential executive officers to leave their existing employment, we occasionally provide for a sign-on bonus. In the case of the recruitment of our CFO, we also offered certain relocation benefits.

Base salaries provide our named executive officers with a fixed amount of consistent compensation and are an important motivating factor in attracting and retaining these individuals. We do not apply specific formulas to determine adjustments to base salary. Historically, the base salaries of our CEO and former President were reviewed and adjusted on a periodic basis by our board of directors. For our CEO, our board of directors considered the recommendations of our former President and also the scope of our CEO’s performance, individual contributions, responsibilities, experience, and prior base salary level. For our former President, our board of directors considered the recommendations of our CEO and also the scope of our former President’s performance, individual contributions, responsibilities, experience, and prior base salary level. For our other continuing named executive officers, our CEO reviewed and recommended adjustments on a periodic basis, in consultation with our former President and board of directors, of base salaries, taking into consideration the scope of the named executive officer’s performance, individual contributions, responsibilities, experience, prior base salary level, and, in the case of a promotion, position. With respect to our named executive officers that were hired in 2011, their initial base salaries were generally established through arm’s-length negotiations at the time each named executive officer was hired, taking into account his qualifications, experience, prior salary level, and the base salaries of our other executive officers. During 2011, our board of directors informally approved base salary increases for our CEO, our former President, and Mr. Farnedi as set forth in the table below. In making these adjustments, our board of directors considered the subjective factors described above, as well as the length of time since the last base salary adjustment, our then-current cash position, and a desire for internal pay equity among our executive officers.

In March 2012, the Committee approved base salary increases for our named executive officers as set forth below. In making this adjustment, the Committee considered the subjective factors described above, as well as the contributions expected from, and responsibilities of, each named executive officer in preparing us to transition from a private company to a publicly-traded company.

In establishing our annual incentive compensation plan, our objective is to provide cash awards linked to company and individual performance, remain competitive in the marketplace and drive performance toward company goals. Corporate and individual key performance goals are established quarterly and evaluated by our CEO (except for his own performance goals which are established and evaluated by our board of directors) following the end of each quarter. In addition, corporate and individual key performance goals are evaluated on an annual basis. Corporate goals focus on overarching objectives for the organization, while individual objectives represent key performance expectations at the departmental or individual level. In setting these objectives, we identify the financial and operational results required to successfully grow the business, while also recognizing that internal and external factors may hinder this progress. As such, these objectives are intended to be challenging to achieve but within reach. Generally, our CEO reviews the objectives for, and achievements of, the named executive officers (other than himself) and shares his evaluations and recommendations with our board of directors. Our board of directors reviews the objectives for, and achievements of, our CEO and determines his incentive compensation. Historically, our CEO, in consultation with our board of directors and, for the 2011 performance period, our Committee in consultation with our CEO, have determined cash award amounts for our named executive officers and the actual achievement against these objectives. While we use a formula to calculate tentative award amounts, the final award approvals are made at the discretion of our board of directors and, for the 2011 performance period, our Committee, in each case, with recommendations by our CEO with respect to the other named executive officers. For the 2011 performance period, the formula used was based on a combination of corporate goals and individual goals. The percentage breakdown between corporate goals and individual goals for each named executive officer is set forth below under “2011 Achievement.” Annual incentive payments are generally subject to a maximum payment at the target amount; however our board of directors and/or the Committee has had the authority to pay discretionary bonuses in excess of target amounts.

For 2011, our annual cash incentive award opportunities were designed to reward our named executive officers based on our performance and the individual named executive officer’s contribution to that performance. Target award opportunities for our CEO and our former President were established by our board of directors. With respect to our other named executive officers, each target award opportunity was based on the contractual rights set forth in his respective offer letter agreement. The 2011 target award opportunities were as follows:

For 2011, the objectives and related performance assessment for our named executive officers were as follows:

Based on the evaluation of the performance results described above, in 2012, the Committee approved the following cash awards for our named executive officers for the 2011 performance period:

In 2012, our Committee determined that the financial thresholds for the 2011 incentive awards were too aggressive and established an incentive arrangement for our CEO and former President to potentially earn, based on 2012 performance, a portion of the incentive award that was not earned in 2011. Accordingly, the Committee determined rollover bonus potentials for our CEO and former President of $55,000 and $50,000, respectively. If we achieved 2012 semi-annual revenue targets that were deemed very challenging, then each applicable executive officer would receive 50% of the applicable rollover bonus potential. If we exceeded these semi-annual targets by more than 5%, then each applicable executive officer would receive 100% of the applicable rollover bonus potential. The rollover bonuses would have been paid, to the extent earned, in July 2012, subject to continued employment of the executive officer at the end of the six month period ending June 30, 2012. If the executive officer’s employment terminates prior to the end of the six month period ending June 30, 2012, then any earned rollover bonus would be pro-rated. The rollover bonus was an incentive opportunity separate from and in addition to any annual 2012 incentive award. While the Company experienced significant revenue growth in the six months ended June 30, 2012 compared to the same period in the prior year, the very challenging revenue targets set by the Committee were not achieved and no rollover bonus was paid.

In addition to our annual bonus opportunities, we occasionally provide for sign-on bonuses as a material inducement to join the company. In 2011, as a result of negotiations with Mr. Aggarwal, we provided Mr. Aggarwal with a $50,000 sign-on bonus payable within 30 days of his start date.

We use stock options to attract, motivate, and incentivize the executive talent necessary to accomplish our business objectives while also providing a significant long-term interest in our success by rewarding the creation of stockholder value. Vesting for stock options is based on continued employment with us, generally over four years, thereby also encouraging the retention of our executive officers. In addition to stock options, we used restricted stock to incentivize our founders in connection with our incorporation.

Historically, we have not applied a formula to determine the size of individual stock options granted to our named executive officers. Instead, our board of directors has generally determined the size of individual grants using its collective business judgment and experience, taking into account, among other factors, the role and responsibility of the individual executive officer, the competitive market for the executive officer’s position and the size, value, and vesting status of existing equity awards. Based upon these factors, our board of directors or the Committee sets the size of each stock option award at a level it considers appropriate to create a meaningful incentive.

Our executive officers generally receive a stock option grant at the time of hire, with only discretionary additional awards thereafter. In addition to the factors considered above, the size of new hire grants was based on arm’s-length negotiations at the time each named executive officer was hired. Our current informal practice is to not provide additional equity awards until after the initial stock option grant has been substantially vested.

During 2011, our board of directors approved grants for our CEO and our former President because their existing founders’ restricted stock had fully vested. In recognition that these refresh grants were overdue, our board of directors provided for vesting credit from 2009, when their original restricted stock grants had fully vested. The size of these stock option grants was intended to provide sufficient equity incentive to align the interests of our CEO and our former President with those of our stockholders. On a similar rationale, our board of directors granted a stock option to Mr. Farnedi because his existing sign-on stock option grant was almost fully vested. In addition, our board of directors approved new hire grants to Messrs. Aggarwal, Levine, and Darling.

The following table summarizes the size of the stock option grants awarded to each named executive officer in 2011:

Following the completion of this offering, we expect that the Committee may make discretionary equity grants shortly following the end of each year.

Our named executive officers receive health and welfare benefits under the same programs and subject to the same terms and conditions as our other salaried employees. These benefits include medical, dental, and vision benefits; health savings accounts; short-term and long-term disability insurance; accidental death and dismemberment insurance; and basic life insurance.

Our named executive officers are eligible to participate in our 401(k) retirement savings plan on the same basis as our other employees who satisfy the plan’s eligibility requirements. We may make discretionary contributions to the plan in any year, subject to certain limits. In 2011, we made matching contributions under our 401(k) retirement savings plan to all eligible participants.

Generally, we have not provided perquisites or other personal benefits to our named executive officers, other than those offered to our other salaried employees. However, in 2011, as an inducement material to his hiring, we offered to provide our CFO, who resides over 50 miles from our offices in San Francisco, with an apartment in San Francisco for his use on a tax-neutral basis so long as Mr. Aggarwal is required to work in San Francisco. At the time of his hiring, we believed that without providing this benefit, we would not have been able to induce Mr. Aggarwal to join us. Currently, we do not view perquisites or other personal benefits as a component of our executive compensation program. All future practices with respect to perquisites or other personal benefits will be approved and subject to periodic review by the Committee.

In August 2012, we entered into confirmatory employment letter agreements with Messrs. Flint and Farnedi that confirm the terms of their employment with us. In addition, the initial terms and conditions of employment for Messrs. Aggarwal, Levine and Darling are set forth in written offer letter agreements. We did not enter into any employment agreement or offer letter agreement with Mr. Inkinen, our co-founder. Each of the agreements with our named executive officers was negotiated on our behalf by our CEO, who consulted with our board of directors, except for our confirmatory employment letter agreement with Mr. Flint, which was negotiated on our behalf by our board of directors. We believe that the confirmatory employment letter and offer letter agreements were necessary to induce these individuals to forego other opportunities or, in the case of the offer letter agreements, to leave their current employment for the uncertainty of a demanding position in a new and unfamiliar organization.

In filling these executive positions, we recognized that it would be necessary to recruit candidates with the requisite experience and skills. Accordingly, we sought to develop competitive compensation packages to attract qualified candidates who could fill our most critical positions. At the same time, we were sensitive to the need to integrate new executive officers into our existing executive compensation structure, balancing both competitive and internal equity considerations.

For a summary of the material terms and conditions of these executive offer letter agreements, see “—Executive Confirmatory Employment Letter and Offer Letter Agreements.”

The confirmatory employment letter and offer letter agreements and/or equity award agreements entered into with certain of our named executive officers provide certain protections in the event of their termination of employment under specified circumstances, including following a change in control of our company. We believe that these protections serve our executive retention objectives by helping our named executive officers maintain continued focus and dedication to their responsibilities to maximize stockholder value, including in the event of certain qualifying terminations of employment or a transaction that could result in a change in control of our company. The terms of these agreements were determined after review by our board of directors of our retention goals for each named executive officer. For a summary of the material terms and conditions of these severance and change in control arrangements, see the section titled “—Potential Payments Upon Termination or Change in Control.”

At this time, the Committee has not adopted stock ownership guidelines with respect to our named executive officers, although it may consider doing so in the future. Prior to the completion of this offering, we will establish an insider trading policy that prohibits, among other things, short sales, hedging of stock ownership positions, and transactions involving derivative securities relating to our common stock.

At this time, we have not implemented a policy regarding retroactive adjustments to any cash or equity-based incentive compensation paid to our executive officers and other employees where the payments were predicated upon the achievement of financial results that were subsequently the subject of a financial restatement. The Committee intends to adopt a general compensation recovery, or clawback, policy covering our annual and long-term incentive award plans and arrangements once we are a publicly-traded company and after the SEC adopts final rules implementing the requirement of Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act.

At this time, we have not implemented a policy regarding the trading of derivatives or the hedging of our equity securities by our employees, including our named executive officers and directors, but expect to do so prior to the completion of this offering.

Generally, Section 162(m) of the Internal Revenue Code disallows a tax deduction to any publicly-held corporation for any remuneration in excess of $1 million paid in any taxable year to its chief executive officer and to certain other highly compensated officers. Remuneration in excess of $1 million may be deducted if, among other things, it qualifies as “performance-based compensation” within the meaning of the Internal Revenue Code.

As we had been a privately-held corporation, we have not previously taken the deductibility limit imposed by Section 162(m) into consideration in setting compensation for our executive officers. Further, under a certain Section 162(m) exception, certain compensation paid pursuant to a compensation plan in existence before the effective date of this offering will not be subject to the $1 million limitation until the earliest of: (i) the expiration of the compensation plan, (ii) a material modification of the compensation plan (as determined under Section 162(m)), (iii) the issuance of all the employer stock and other compensation allocated under the compensation plan, or (iv) the first meeting of stockholders at which directors are elected after the close of the third calendar year following the year in which the offering occurs. We expect that, where reasonably practicable, we will seek to qualify the variable compensation paid to our executive officers under the “performance-based compensation” exemption from the deductibility limit. As such, in approving the amount and form of compensation for our executive officers in the future, we will consider all elements of the cost to us of providing such compensation, including the potential impact of Section 162(m). The Committee may, in its judgment, authorize compensation payments that do not comply with an exemption from the deductibility limit under Section 162(m) when it believes that such payments are appropriate to attract and retain executive talent.

We did not provide any executive officer, including any named executive officer, with a “gross-up” or other reimbursement payment for any tax liability that he or she might owe as a result of the application of Sections 280G, 4999, or 409A of the Internal Revenue Code during fiscal 2011, and we have not agreed and are

not otherwise obligated to provide any named executive officer with such a “gross-up” or other reimbursement. Sections 280G and 4999 of the Internal Revenue Code provide that executive officers and directors who hold significant equity interests and certain other service providers may be subject to an excise tax if they receive payments or benefits in connection with a change in control that exceeds certain prescribed limits and that we, or a successor, may forfeit a deduction on the amounts subject to this additional tax. Section 409A also imposes additional significant taxes on the individual in the event that an executive officer, director, or other service provider receives “deferred compensation” that does not meet the requirements of Section 409A of the Internal Revenue Code.

We follow Financial Accounting Standards Board Accounting Standards Codification Topic 718, or ASC Topic 718, formerly known as SFAS 123(R), for our equity-based awards. ASC Topic 718 requires companies to measure the compensation expense for all equity-based payment awards made to employees and directors, including stock options and restricted stock awards, based on the grant date “fair value” of these awards. This calculation is performed for accounting purposes and reported in the compensation tables below, even though our executive officers may never realize any value from their awards. ASC Topic 718 also requires companies to recognize the compensation cost of their equity-based compensation awards in their income statements over the period that an executive officer is required to render service in exchange for the option or other award.

Our management assesses and discusses with the Committee our compensation policies and practices for our employees as they relate to our overall risk management, and based upon this assessment, we believe that any risks arising from such policies and practices are not reasonably likely to have a material adverse effect on us.

The following table provides information regarding the total compensation for services rendered in all capacities that was earned by each individual who served as our principal executive officer or principal financial officer at any time during fiscal 2011, and our three other named executive officers who were serving as executive officers as of December 31, 2011. These individuals were our named executive officers for fiscal 2011.

The following table presents information regarding grants of plan-based awards made to our named executive officers during fiscal 2011.

The following table sets forth information regarding outstanding stock options held by our named executive officers at the end of fiscal 2011:

We do not provide a pension plan for our employees, and none of our named executive officers participated in a nonqualified deferred compensation plan during 2011.

We entered into a confirmatory employment letter agreement with Mr. Flint, our CEO, in August 2012. The confirmatory employment letter agreement has no specific term and constitutes at-will employment. Mr. Flint is eligible for an annual incentive bonus of $110,000, subject to achievement of specific performance metrics. In addition, Mr. Flint was eligible for a one-time rollover bonus of $55,000 in the six months ended June 30, 2012 that was not earned.

We had not entered into an employment agreement or offer letter agreement with Mr. Inkinen. In 2012, in connection with his termination of employment, we entered into a transition agreement with Mr. Inkinen. For a summary of the material terms and conditions of the transition agreement, see “—Sami Inkinen Transition Agreement.”

We entered into an offer letter agreement with Mr. Aggarwal, our CFO, in October 2011. The offer letter agreement has no specific term and constitutes at-will employment. Mr. Aggarwal was provided with a $50,000 sign-on bonus payable within 30 days of his joining us. The sign-on bonus is subject to repayment if Mr. Aggarwal resigns within 12 months of his start date. Mr. Aggarwal is eligible for an annual incentive bonus of $100,000, subject to achievement of specific performance metrics. Mr. Aggarwal’s offer letter agreement provides that, in the event his employment is either terminated by us without “cause” (as defined below) or he resigns for “good reason” (as defined below), within 12 months following a change in control, then, in each case, Mr. Aggarwal will be entitled to accelerated vesting in 50% of the then-unvested shares subject to his sign-on stock option award. Also, we reimburse Mr. Aggarwal for an apartment in San Francisco on a tax-neutral basis so long as Mr. Aggarwal is required to work in San Francisco.

We entered into an offer letter agreement with Mr. Levine, our COO, in February 2011. The offer letter agreement has no specific term and constitutes at-will employment. Mr. Levine is eligible for an annual incentive bonus of $100,000, subject to achievement of specific performance metrics. Mr. Levine’s offer letter agreement provides that, in the event his employment is either terminated by us without “cause” (as defined below) or he resigns for “good reason” (as defined below), within 12 months following a change in control, then, in each case, Mr. Levine will be entitled to accelerated vesting in 50% of the then-unvested shares subject to his sign-on stock option award.

We entered into a confirmatory employment letter agreement with Mr. Farnedi, our Vice President, Engineering, in August 2012. The confirmatory employment letter agreement has no specific term and constitutes at-will employment. Mr. Farnedi’s confirmatory employment letter agreement provides that Mr. Farnedi is eligible for an annual incentive bonus of $31,000, subject to achievement of specific performance metrics. Mr. Farnedi’s confirmatory employment letter agreement provides that, in the event his employment is either terminated by us without “cause” (as defined below) or he resigns for “good reason” (as defined below), within 12 months following a change in control, then, in each case, Mr. Farnedi will be entitled to accelerated vesting in 50% of the then-unvested shares subject to the stock option granted to Mr. Farnedi in July 2012.

We entered into an offer letter agreement with Mr. Darling, our Vice President, General Counsel, and Corporate Secretary, in October 2011. The offer letter agreement has no specific term and constitutes at-will

employment. Mr. Darling is eligible for an annual incentive bonus of $50,000, subject to achievement of specific performance metrics. Mr. Darling’s offer letter agreement provides that, in the event his employment is either terminated by us without “cause” (as defined below) or he resigns for “good reason” (as defined below), within 12 months following a change in control, then, in each case, Mr. Darling will be entitled to accelerated vesting in 50% of the then-unvested shares subject to his sign-on stock option award.

For purposes of the offer letter agreements and confirmatory employment letter agreement with Mr. Farnedi, “cause” means dishonesty, fraud, serious misconduct, unauthorized use or disclosure of confidential information or trade secrets, or conduct prohibited by criminal law (except minor violations), in each case as determined by our board of directors, whose determination shall be conclusive and binding.

For purposes of the offer letter agreements of Messrs. Aggarwal, Levine, and Darling and the confirmatory employment letter agreement with Mr. Farnedi, “good reason” means:

We entered into a transition agreement and release with Sami Inkinen, our former President, dated March 28, 2012. The agreement provides that Mr. Inkinen’s employment terminated on March 31, 2012 and in consideration for executing a release, Mr. Inkinen received: (1) continuing payments of his then-current base salary for six months; (2) continued eligibility to receive the rollover bonus described above on a pro-rated basis, subject to achievement of the 2012 performance measures; (3) reimbursement for mobile phone, voice, and data service expenses, up to $200 per month, for six months; and (4) COBRA reimbursements for a period of six months, or until Mr. Inkinen has secured other employment and has become eligible for health benefits from such new employer, whichever occurs first.

If we are subject to a “company transaction” (as defined below) that is not a related party transaction, any unpaid severance shall be accelerated and paid in a lump sum in the next payroll date following the closing of such transaction.

As a part of the transition agreement, Mr. Inkinen agreed to continue to serve as a member of our board of directors until at least December 31, 2013. We will reimburse Mr. Inkinen for reasonable travel and other incidental expenses approved by us related to director service, so long as Mr. Inkinen provides us with appropriate receipts or other relevant documentation.

The transition agreement also provides that Mr. Inkinen will continue to vest in his outstanding stock option through September 30, 2012. If there is a company transaction and Mr. Inkinen’s service as a director of the company is terminated involuntarily prior to September 30, 2012, Mr. Inkinen’s service with us will be deemed to have been involuntarily terminated as of the date of termination for purposes of the stock option agreement, dated February 8, 2011. Mr. Inkinen will be entitled to exercise his outstanding stock option until the later of one year after Mr. Inkinen ceases to provide any services to us or December 31, 2013 (but in no event later than the original 10-year expiration date set forth in the grant notice related to such stock option).

For purposes of Mr. Inkinen’s transition agreement, “company transaction” means generally the consummation of:

provided, however, that in all cases a company transaction shall not include a related party transaction.

The following table provides information concerning the estimated payments and benefits that would be provided in the circumstances described above for each of our named executive officers. For purposes of the table, a qualifying termination of employment is considered “in connection with a change in control” if such involuntary termination without cause or voluntary termination for good reason occurs within the period 12 months, unless otherwise described in the footnotes below, following the “change in control” (as defined in each agreement). Payments and benefits are estimated assuming that the triggering event took place on December 31, 2011. There can be no assurance that an actual triggering event would produce the same or similar results as those estimated below if such event occurs on any other date or at any other price, or if any other assumption used to estimate potential payments and benefits is not correct. Due to the number of factors that affect the nature and amount of any potential payments or benefits, any actual payments and benefits may be different.

Our board of directors has adopted, and our stockholders have approved, a 2012 Equity Incentive Plan, or the 2012 Plan. The 2012 Plan will be effective on the business day immediately prior to the effective date of the registration statement of which this prospectus forms a part. The 2012 Plan provides for the grant of incentive stock options, within the meaning of Section 422 of the Internal Revenue Code, to our employees and any parent and subsidiary corporations’ employees, and for the grant of nonstatutory stock options, restricted stock, restricted stock units, stock appreciation rights, performance units, and performance shares to our employees, directors, and consultants and our parent and subsidiary corporations’ employees and consultants.

Authorized Shares. A total of 2,370,000 shares of our common stock have been reserved for issuance pursuant to the 2012 Plan, of which no awards are issued and outstanding. In addition, the shares reserved for issuance under the 2012 Plan also include shares returned to the 2005 Plan as the result of expiration or termination of awards (provided that the maximum number of shares that may be added to the 2012 Plan pursuant to this provision is 1,000,000 shares). The number of shares available for issuance under the 2012 Plan will also include an annual increase on the first day of each fiscal year beginning in 2013, equal to the least of:

Plan Administration. Our board of directors or the Committee will administer the 2012 Plan. Subject to the provisions of the 2012 Plan, the administrator has the power to determine the terms of the awards, including the exercise price, the number of shares subject to each such award, the exercisability of the awards, and the form of consideration, if any, payable upon exercise. The administrator also has the authority to amend existing awards to reduce their exercise price, to allow participants the opportunity to transfer outstanding awards to a financial institution or other person or entity selected by the administrator, and to institute an exchange program by which outstanding awards may be surrendered in exchange for awards with a higher or lower exercise price.

Stock Options. The exercise price of options granted under the 2012 Plan must at least be equal to the fair market value of our common stock on the date of grant. The term of an incentive stock option may not exceed 10 years, except that with respect to any employee who owns more than 10% of the voting power of all classes of our outstanding stock, the term must not exceed five years and the exercise price must equal at least 110% of the fair market value of our common stock on the grant date. Subject to the provisions of the 2012 Plan, the administrator determines the term of all other options. After the termination of service of an employee, director or consultant, he or she may exercise his or her option for the period of time stated in his or her option agreement. Generally, if termination is due to death or disability, the option will remain exercisable for 12 months. In all other cases, the option will generally remain exercisable for three months following the termination of service. However, in no event may an option be exercised later than the expiration of its term.

Stock Appreciation Rights. Stock appreciation rights may be granted under the 2012 Plan. Stock appreciation rights allow the recipient to receive the appreciation in the fair market value of shares of our common stock between the exercise date and the date of grant. Subject to the provisions of the 2012 Plan, the administrator determines the terms of stock appreciation rights, including when such rights become exercisable and whether to pay any increased appreciation in cash or with shares of our common stock, or a combination thereof, except that the per share exercise price for the shares to be issued pursuant to the exercise of a stock appreciation right will be no less than 100% of the fair market value per share on the date of grant.

Restricted Stock. Restricted stock may be granted under the 2012 Plan. Restricted stock awards are grants of shares of our common stock that vest in accordance with terms and conditions established by the administrator. The administrator will determine the number of shares of restricted stock granted to any employee, director, or consultant. The administrator may impose whatever conditions to vesting it determines to be appropriate (for example, the administrator may set restrictions based on the achievement of specific performance goals or continued service to us); provided, however, that the administrator, in its sole discretion, may accelerate the time at which any restrictions will lapse or be removed. Shares of restricted stock that do not vest are subject to our right of repurchase or forfeiture.

Restricted Stock Units. Restricted stock units may be granted under the 2012 Plan. Restricted stock units are bookkeeping entries representing an amount equal to the fair market value of one share of our common stock. The administrator determines the terms and conditions of restricted stock units, including the vesting criteria (which may include accomplishing specified performance criteria or continued service to us) and the form and timing of payment. Notwithstanding the foregoing, the administrator, in its sole discretion, may accelerate the time at which any restrictions will lapse or be removed.

Performance Units and Performance Shares. Performance units and performance shares may be granted under the 2012 Plan. Performance units and performance shares are awards that will result in a payment to a participant only if performance goals established by the administrator are achieved or the awards otherwise vest. The administrator will establish organizational or individual performance goals in its discretion, which, depending on the extent to which they are met, will determine the number and/or the value of performance units and performance shares to be paid out to participants. After the grant of a performance unit or performance share, the administrator, in its sole discretion, may reduce or waive any performance criteria or other vesting provisions for such performance units or performance shares. Performance units shall have an initial dollar value established by the administrator prior to the grant date. Performance shares shall have an initial value equal to the fair market value of our common stock on the grant date. The administrator, in its sole discretion, may pay earned performance units or performance shares in the form of cash, in shares or in some combination thereof.

Outside Directors. The 2012 Plan provides that all non-employee directors will be eligible to receive all types of awards (except for incentive stock options) under the 2012 Plan.

Non-Transferability of Awards. Unless the administrator provides otherwise, the 2012 Plan generally does not allow for the transfer of awards and only the recipient of an award may exercise an award during his or her lifetime.

Certain Adjustments. In the event of certain changes in our capitalization, to prevent diminution or enlargement of the benefits or potential benefits available under the 2012 Plan, the administrator will adjust the number and class of shares that may be delivered under the Plan and/or the number, class, and price of shares covered by each outstanding award, and the numerical share limits set forth in the 2012 Plan. In the event of our proposed liquidation or dissolution, the administrator will notify participants as soon as practicable and all awards will terminate immediately prior to the consummation of such proposed transaction.

Merger or Change in Control. The 2012 Plan provides that in the event of a merger or change in control, as defined under the 2012 Plan, each outstanding award will be treated as the administrator determines, except that if a successor corporation or its parent or subsidiary does not assume or substitute an equivalent award for any outstanding award, then such award will fully vest, all restrictions on such award will lapse, all performance goals or other vesting criteria applicable to such award will be deemed achieved at 100% of target levels and such award will become fully exercisable, if applicable, for a specified period prior to the transaction. The award will then terminate upon the expiration of the specified period of time. If the service of an outside director is terminated on or following a change in control, other than pursuant to a voluntary resignation, his or her options, restricted stock units and stock appreciation rights, if any, will vest fully and become immediately exercisable, all restrictions on his or her restricted stock will lapse, all performance goals or other vesting requirements for his or her performance shares and units will be deemed achieved at 100% of target levels, and all other terms and conditions will be deemed met.

Amendment, Termination. Our board of directors has the authority to amend, suspend, or terminate the 2012 Plan provided such action does not impair the existing rights of any participant. The 2012 Plan automatically terminates in 2022, unless we terminate it sooner.

Our board of directors adopted our 2005 Plan in June 2005, and our stockholders approved it in June 2005. Our 2005 Plan was most recently amended in February 2012.

Authorized Shares. As of June 30, 2012, an aggregate of 5,141,271 shares of our common stock were reserved for issuance under our 2005 Plan. Our 2005 Plan provided for the grant of incentive stock options, nonqualified stock options, restricted stock, stock appreciation rights, stock awards, restricted stock, and restricted stock units. As of June 30, 2012, options to purchase 3,429,470 shares of our common stock remained outstanding under our 2005 Plan (which includes 89,100 shares to be sold in this offering by certain selling stockholders upon the exercise of options).

Plan Administration. The Committee currently administers our 2005 Plan. Subject to the provisions of our 2005 Plan, the administrator has the power to interpret and administer our 2005 Plan and any agreement thereunder and to determine the terms of awards (including the recipients), the number of shares subject to each award, the exercise price (if any), the fair market value of a share of our common stock, the vesting schedule applicable to the awards together with any vesting acceleration, and the terms of the award agreement for use under our 2005 Plan. The administrator may, at any time, authorize the issue of new awards for the surrender and cancellation of any outstanding award with the consent of a participant. The administrator may also buy out an award previously granted for cash, shares, or other consideration as the administrator and the participant may agree.

Options. Stock options may be granted under our 2005 Plan. The exercise price per share of all options must equal at least 85% of the fair market value per share of our common stock on the date of grant, and the exercise price per share of incentive stock options must equal at least 100% of the fair market value per share of our common stock on the date of grant. The term of an incentive stock option may not exceed 10 years. An incentive stock option held by a participant who owns more than 10% of the total combined voting power of all classes of our stock, or any parent or subsidiary corporations, may not have a term in excess of five years and must have an exercise price of at least 110% of the fair market value per share of our common stock on the date of grant. The administrator will determine the methods of payment of the exercise price of an option, which may include cash, shares, or certain other property, or other consideration acceptable to the administrator. After the termination of service of an employee, director, or consultant, the participant may generally exercise his or her options, to the extent vested as of such date of termination, for three months after termination. If termination is due to death, disability or retirement, the option will generally remain exercisable, to the extent vested as of such date of termination, until the one-year anniversary of such termination. However, in no event may an option be exercised later than the expiration of its term. If termination is for cause, then an option automatically expires upon first notification to the participant of such termination.

Stock Appreciation Rights. Stock appreciation rights may be granted under the 2005 Plan. Stock appreciation rights allow the recipient to receive the appreciation in the fair market value of shares of our common stock between the exercise date and the date of grant. Subject to the provisions of the 2005 Plan, the administrator determines the terms of stock appreciation rights, including when such rights become exercisable and whether to pay any increased appreciation in cash or with shares of our common stock, or a combination thereof, except that the per share exercise price for the shares to be issued pursuant to the exercise of a stock appreciation right granted in tandem with an option will be equal to the exercise price of the related option.

Stock Awards. Stock awards may be granted under our 2005 Plan. Stock awards are grants of shares of our common stock, the rights of ownership of which are not subject to restrictions prescribed by the administrator.

Restricted Stock. Restricted stock may be granted under our 2005 Plan. Restricted stock awards are grants of shares of our common stock that are subject to various restrictions, including restrictions on transferability and forfeiture provisions. Shares of restricted stock will vest, and the restrictions on such shares will lapse, in accordance with terms and conditions established by the administrator.

Stock Units. Stock units may be granted under the 2005 Plan. Stock units are bookkeeping entries representing an amount equal to the fair market value of one share of our common stock. The administrator determines the terms and conditions of restricted stock units, including the vesting criteria (which may include accomplishing specified performance criteria or continued service to us) and the form and timing of payment. Notwithstanding the foregoing, the administrator, in its sole discretion may accelerate the time at which any restrictions will lapse or be removed.

Transferability of Awards. Our 2005 Plan generally does not allow for the transfer of awards, and only the recipient of an award may exercise such an award during his or her lifetime.

Certain Adjustment. In the event of certain changes in our capitalization, the number of shares reserved under our 2005 Plan, the exercise prices of and the number of shares subject to outstanding options, and the purchase price of and the numbers of shares subject to outstanding awards will be proportionately adjusted, subject to any required action by our board of directors.

Merger or Change in Control. Our 2005 Plan provides that, in the event of a merger, change in control, or other company transaction, as defined under our 2005 Plan, each outstanding award may be assumed or substituted for an equivalent award. In the event that awards are not assumed or substituted for, then the vesting of outstanding awards will be accelerated, and stock options will become exercisable in full prior to such corporate transaction. Stock options will then generally terminate immediately prior to the corporate transaction.

Amendment, Termination. Our board of directors may amend our 2005 Plan at any time, provided that such amendment does not impair the rights under outstanding awards without the award holder’s written consent. Upon completion of this offering, our 2005 Plan will be terminated and no further awards will be granted thereunder. All outstanding awards will continue to be governed by their existing terms.

Our SMT Bonus Plan, or the Bonus Plan, was adopted by the Committee in March 2012. The Bonus Plan allows the Committee to provide cash incentive awards to selected executives, officers, or key employees, including our named executive officers, based upon performance goals established by the Committee.

Under the Bonus Plan, the Committee determines the performance goals applicable to any award, which goals may include, without limitation: attainment of research and development milestones; bookings; business divestitures and acquisitions; cash flow; cash position; contract awards or backlog; customer renewals; customer retention rates from an acquired company, business unit, or division; earnings (which may include earnings before interest, taxes, depreciation and amortization, earnings before taxes, and net earnings); earnings per share; expenses; gross margin; growth in stockholder value relative to the moving average of the S&P 500 Index or another index; internal rate of return; inventory turns; inventory levels; market share; net income; net profit; net sales; new product development; new product invention or innovation; number of customers; operating cash flow; operating expenses; operating income; operating margin; overhead or other expense reduction; product defect measures; product release timelines; productivity; profit; return on assets; return on capital; return on equity; return on investment; return on sales; revenue; revenue growth; sales results; sales growth; stock price; time to market; total stockholder return; working capital; and individual objectives such as peer reviews or other subjective or objective criteria. Performance goals that include our financial results may be determined in accordance with GAAP or such financial results may consist of non-GAAP financial measures and any actual results may be adjusted by the Committee for one-time items or unbudgeted or unexpected items when

determining whether the performance goals have been met. The goals may be on the basis of any factors the Committee determines relevant, and may be adjusted on an individual, divisional, business unit, or company-wide basis. The performance goals may differ from participant to participant and from award to award.

The Committee may, in its sole discretion and at any time, increase, reduce or eliminate a participant’s actual award and/or increase, reduce or eliminate the amount allocated to the bonus pool for a particular performance period. The actual award may be below, at or above a participant’s target award, in the Committee’s discretion. The Committee may determine the amount of any reduction on the basis of such factors as it deems relevant, and it is not required to establish any allocation or weighting with respect to the factors it considers.

Actual awards are paid in cash only after they are earned, which usually requires continued employment through the date a bonus is paid. Payment of bonuses occurs as soon as administratively practicable after they are earned, but no later than the dates set forth in the Bonus Plan.

The Committee has the authority to amend, alter, suspend or terminate the Bonus Plan provided such action does not impair the existing rights of any participant with respect to any earned bonus.

We maintain a tax-qualified retirement plan that provides eligible employees with an opportunity to save for retirement on a tax-advantaged basis. All participants’ interests in their deferrals are 100% vested when contributed. In fiscal 2011, we made matching contributions into the 401(k) plan. Our contributions to the 401(k) plan are discretionary and fully vested when contributed. Pre-tax contributions are allocated to each participant’s individual account and are then invested in selected investment alternatives according to the participants’ directions. The 401(k) plan is intended to qualify under Sections 401(a) and 501(a) of the Internal Revenue Code. As a tax-qualified retirement plan, contributions to the 401(k) plan and earnings on those contributions are not taxable to the employees until distributed from the 401(k) plan, and all contributions are deductible by us when made.

In addition to the compensation arrangements, including employment, termination of employment and change in control arrangements and indemnification arrangements, discussed, when required, in the sections titled “Management” and “Executive Compensation” and the registration rights described in the section titled “Description of Capital Stock—Registration Rights,” the following is a description of each transaction since January 1, 2009 and each currently proposed transaction in which:

We entered into a transition agreement and release with Sami Inkinen, our former President, dated March 28, 2012. For a more detailed description of this agreement, see the section titled “Executive Compensation—Sami Inkinen Transition Agreement.”

In January 2012, we entered into a letter agreement with Gregory Waldorf, a non-employee member of our board of directors. See the section titled “Management—Non-Employee Director Compensation—Gregory Waldorf Letter Agreement” for a more detailed description of this agreement.

In May 2012, we entered into a letter agreement with Erik Bardman, a non-employee member of our board of directors. See the section titled “Management — Non-Employee Director Compensation — Erik Bardman Letter Agreement” for a more detailed description of this agreement.

On May 8, 2008, we entered into a Third Amended and Restated Investor Rights Agreement with the holders of our outstanding convertible preferred stock, including entities affiliated with Accel Partners, Fayez Sarofim Investment Partnership, and Sequoia Capital, which each hold more than 5% of our outstanding capital stock, and Peter Flint and Sami Inkinen, our co-founders. As of June 30, 2012, the holders of 18,206,604 shares of our common stock, including our common stock issuable in connection with the automatic conversion of all outstanding shares of our convertible preferred stock into common stock, are entitled to rights with respect to the registration of their shares following this offering under the Securities Act. See the section titled “Description of Capital Stock—Registration Rights” for more information regarding these registration rights.

We are a party to a right of first refusal and co-sale agreement which imposes restrictions on the transfer of our capital stock. Upon the closing of this offering, the right of first refusal and co-sale agreement will terminate and the restrictions on the transfer of our capital stock set forth in this agreement will no longer apply.

We are party to a voting agreement under which certain holders of our capital stock, including entities with which one of our directors is affiliated, have agreed to vote their shares on certain matters, including with respect to the election of directors. Upon the closing of this offering, the voting agreement will terminate and none of our stockholders will have any special rights regarding the election or designation of members of our board of directors or the voting of capital stock of the company.

We have entered into confirmatory employment letter and offer letter agreements with certain of our executive officers. See the section titled “Executive Compensation—Executive Confirmatory Employment Letter and Offer Letter Agreements” for more information regarding these agreements.

We have granted stock options to our executive officers and certain of our directors. See the sections titled “Executive Compensation—Grants of Plan-Based Awards Table” and “Management—Non-Employee Director Compensation” for a description of these options.

We have entered into change in control arrangements with certain of our executive officers that, among other things, provide for certain severance and change in control benefits. See the section titled “Executive Compensation—Potential Payments upon Termination or Change in Control” for more information regarding these agreements.

Other than as described above under this section titled “Certain Relationships and Related Person Transactions,” since January 1, 2009, we have not entered into any transactions, nor are there any currently proposed transactions, between us and a related party where the amount involved exceeds, or would exceed, $120,000, and in which any related person had or will have a direct or indirect material interest. We believe the terms of the transactions described above were comparable to terms we could have obtained in arm’s-length dealings with unrelated third parties.

Prior to the completion of this offering, we expect to adopt an amended and restated certificate of incorporation, which will become effective immediately prior to the completion of this offering, and which will contain provisions that limit the liability of our directors for monetary damages to the fullest extent permitted by Delaware law. Consequently, our directors will not be personally liable to us or our stockholders for monetary damages for any breach of fiduciary duties as directors, except liability for the following:

Any amendment to, or repeal of, these provisions will not eliminate or reduce the effect of these provisions in respect of any act, omission or claim that occurred or arose prior to that amendment or repeal. If the Delaware General Corporation Law is amended to provide for further limitations on the personal liability of directors of corporations, then the personal liability of our directors will be further limited to the greatest extent permitted by the Delaware General Corporation Law.

In addition, prior to the completion of this offering, we expect to adopt amended and restated bylaws which will provide that we will indemnify, to the fullest extent permitted by law, any person who is or was a party or is threatened to be made a party to any action, suit or proceeding by reason of the fact that he or she is or was one of our directors or officers or is or was serving at our request as a director or officer of another corporation, partnership, joint venture, trust, or other enterprise. Our amended and restated bylaws are expected to provide that we may indemnify to the fullest extent permitted by law any person who is or was a party or is threatened to be made a party to any action, suit, or proceeding by reason of the fact that he or she is or was one of our employees or agents or is or was serving at our request as an employee or agent of another corporation,

partnership, joint venture, trust, or other enterprise. Our amended and restated bylaws will also provide that we must advance expenses incurred by or on behalf of a director or officer in advance of the final disposition of any action or proceeding, subject to very limited exceptions.

Further, prior to the completion of this offering, we expect to enter into indemnification agreements with each of our directors and executive officers that may be broader than the specific indemnification provisions contained in the Delaware General Corporation Law. These indemnification agreements will require us, among other things, to indemnify our directors and executive officers against liabilities that may arise by reason of their status or service. These indemnification agreements will also require us to advance all expenses incurred by the directors and executive officers in investigating or defending any such action, suit, or proceeding. We believe that these agreements are necessary to attract and retain qualified individuals to serve as directors and executive officers.

The limitation of liability and indemnification provisions that are expected to be included in our amended and restated certificate of incorporation, amended restated bylaws, and in indemnification agreements that we enter into with our directors and executive officers may discourage stockholders from bringing a lawsuit against our directors and executive officers for breach of their fiduciary duties. They may also reduce the likelihood of derivative litigation against our directors and executive officers, even though an action, if successful, might benefit us and other stockholders. Further, a stockholder’s investment may be adversely affected to the extent that we pay the costs of settlement and damage awards against directors and executive officers as required by these indemnification provisions. At present, we are not aware of any pending litigation or proceeding involving any person who is or was one of our directors, officers, employees or other agents or is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, for which indemnification is sought, and we are not aware of any threatened litigation that may result in claims for indemnification.

We have obtained insurance policies under which, subject to the limitations of the policies, coverage is provided to our directors and executive officers against loss arising from claims made by reason of breach of fiduciary duty or other wrongful acts as a director or executive officer, including claims relating to public securities matters, and to us with respect to payments that may be made by us to these directors and executive officers pursuant to our indemnification obligations or otherwise as a matter of law.

Certain of our non-employee directors may, through their relationships with their employers, be insured and/or indemnified against certain liabilities incurred in their capacity as members of our board of directors.

The underwriting agreement provides for indemnification by the underwriters of us and our officers, directors and employees for certain liabilities arising under the Securities Act of 1933, or the Securities Act, or otherwise.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling our company pursuant to the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Following the completion of this offering, the audit committee will have the primary responsibility for reviewing and approving or disapproving “related party transactions,” which are transactions between us and related persons in which the aggregate amount involved exceeds or may be expected to exceed $120,000 and in which a related person has or will have a direct or indirect material interest. We have adopted a policy regarding transactions between us and related persons. For purposes of this policy, a related person is defined as a director, executive officer, nominee for director, or greater than 5% beneficial owner of our common stock, in each case since the beginning of the most recently completed year, and their immediate family members. Our audit committee charter that will be in effect upon the completion of this offering provides that the audit committee shall review and approve or disapprove any related party transactions.

The following table sets forth certain information with respect to the beneficial ownership of our common stock as of August 31, 2012, and as adjusted to reflect the sale of common stock offered by us in this offering assuming no exercise of the underwriters’ option to purchase additional shares, for:

We have determined beneficial ownership in accordance with the rules of the SEC, and thus it represents sole or shared voting or investment power with respect to our securities. Unless otherwise indicated below, to our knowledge, the persons and entities named in the table have sole voting and sole investment power with respect to all shares that they beneficially owned, subject to community property laws where applicable. We have deemed shares of our common stock subject to options that are currently exercisable or exercisable within 60 days of August 31, 2012 to be outstanding and to be beneficially owned by the person holding the option for the purpose of computing the percentage ownership of that person but have not treated them as outstanding for the purpose of computing the percentage ownership of any other person.

We have based percentage ownership of our common stock before this offering on 21,301,147 shares of our common stock outstanding as of August 31, 2012, which includes 14,161,444 shares of common stock resulting from the automatic conversion of all outstanding shares of our convertible preferred stock immediately prior to the completion of this offering, as if this conversion had occurred as of August 31, 2012. Percentage ownership of our common stock after this offering assumes our sale of 5,000,000 shares of common stock in this offering. Percentage ownership of our common stock after this offering also assumes the issuance of 89,100 shares to be sold in this offering by certain selling stockholders upon the exercise of options at the closing of this offering.

Unless otherwise indicated, the address of each beneficial owner listed in the table below is c/o Trulia, Inc., 116 New Montgomery Street, Suite 300, San Francisco, California 94105.

The following description summarizes certain important terms of our capital stock, as they are expected to be in effect upon the closing of this offering. We expect to adopt an amended and restated certificate of incorporation and amended and restated bylaws in connection with this offering, and this description summarizes the provisions that are expected to be included in such documents. Because it is only a summary, it does not contain all the information that may be important to you. For a complete description of the matters set forth in this “Description of Capital Stock,” you should refer to our amended and restated certificate of incorporation and amended and restated bylaws and investor rights agreement, which are included as exhibits to the registration statement of which this prospectus forms a part, and to the applicable provisions of Delaware law. Immediately following the closing of this offering, our authorized capital stock will consist of 1,000,000,000 shares of common stock, $0.00001 par value per share, and 20,000,000 shares of undesignated preferred stock, $0.00001 par value per share.

Assuming the conversion of all outstanding shares of our convertible preferred stock into shares of our common stock, which will occur immediately prior to the completion of this offering, as of June 30, 2012, there were 21,287,554 shares of our common stock outstanding, held by 160 stockholders of record, and no shares of our convertible preferred stock outstanding. Our board of directors is authorized, without stockholder approval except as required by the listing standards of the New York Stock Exchange to issue additional shares of our capital stock.

Subject to preferences that may apply to any shares of preferred stock outstanding at the time, the holders of our common stock are entitled to receive dividends out of funds legally available if our board of directors, in its discretion, determines to issue dividends and then only at the times and in the amounts that our board of directors may determine. In addition, the terms of our credit facility currently prohibit us from paying cash dividends on our capital stock. See the section titled “Dividend Policy” for more information.

Holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders. We have not provided for cumulative voting for the election of directors in our amended and restated certificate of incorporation. Our amended and restated certificate of incorporation establishes a classified board of directors that is divided into three classes with staggered three-year terms. Only the directors in one class will be subject to election by a plurality of the votes cast at each annual meeting of our stockholders, with the directors in the other classes continuing for the remainder of their respective three-year terms.

Our common stock is not entitled to preemptive rights, and is not subject to conversion, redemption, or sinking fund provisions.

If we become subject to a liquidation, dissolution or winding-up, the assets legally available for distribution to our stockholders would be distributable ratably among the holders of our common stock and any participating preferred stock outstanding at that time, subject to prior satisfaction of all outstanding debt and liabilities and the preferential rights of and the payment of liquidation preferences, if any, on any outstanding shares of preferred stock.

All of the outstanding shares of our common stock are, and the shares of our common stock to be issued pursuant to this offering will be, fully paid and non-assessable.

Our board of directors is authorized, subject to limitations prescribed by Delaware law, to issue preferred stock in one or more series, to establish from time to time the number of shares to be included in each series, and to fix the designation, powers, preferences, and rights of the shares of each series and any of its qualifications, limitations or restrictions, in each case without further vote or action by our stockholders. Our board of directors can also increase or decrease the number of shares of any series of preferred stock, but not below the number of shares of that series then outstanding, without any further vote or action by our stockholders. Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of our common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring, or preventing a change in our control of our company and might adversely affect the market price of our common stock and the voting and other rights of the holders of our common stock. We have no current plan to issue any shares of preferred stock.

As of June 30, 2012, we had outstanding options to purchase an aggregate of 3,429,470 shares of our common stock, with a weighted average exercise price of $4.35, pursuant to our 2005 Plan. Certain selling stockholders will acquire an aggregate of 89,100 shares of our common stock upon the exercise of options outstanding as of June 30, 2012 in order to sell those shares in this offering.

As of June 30, 2012, we had outstanding a warrant to purchase up to 120,961 shares of our Series D preferred stock at an exercise price of $8.47 per share, which we issued in connection with the credit facility, pursuant to which 56,054 shares of our Series D preferred stock could be purchased as of June 30, 2012. The remaining 64,907 shares of Series D preferred stock issuable pursuant to this warrant may be purchased in the event that we choose to drawdown additional funds under the credit facility. Upon the conversion of all of our convertible preferred stock into common stock immediately prior to the completion of this offering, this warrant will be exercisable for an equivalent number of shares of common stock and will remain exercisable for five years from the offering date set forth on the cover page of this prospectus. In addition, this warrant has a net exercise provision pursuant to which the holder may, in lieu of payment of the exercise price in cash, surrender the warrant and receive a net amount of shares based on the fair market value of our Series D preferred stock or common stock, as applicable, at the time of exercise of the warrant after deduction of the aggregate exercise price.

As of June 30, 2012, we also had an outstanding warrant to purchase 44,646 shares of our common stock at an exercise price of $4.29 per share. We expect that this warrant will be exercised prior to the completion of this offering.

After the completion of this offering, certain holders of our common stock will be entitled to rights with respect to the registration of their shares under the Securities Act of 1933, or the Securities Act. These registration rights are contained in our Third Amended and Restated Investor Rights Agreement, or IRA, dated as of May 8, 2008, as amended on September 15, 2011. We, along with certain holders of our common stock and the holders of our Series A preferred stock, Series B preferred stock, Series C preferred stock, and Series D preferred stock are parties to the IRA. The registration rights set forth in the IRA will expire five years following

the completion of this offering, or, with respect to any particular stockholder, when such stockholder is able to sell all of its shares pursuant to Rule 144 of the Securities Act or a similar exemption during any 90-day period. We will pay the registration expenses (other than underwriting discounts, selling commissions and stock transfer taxes) of the holders of the shares registered pursuant to the registrations described below. In an underwritten offering, the managing underwriter, if any, has the right, subject to specified conditions, to limit the number of shares such holders may include. In connection with this offering, each stockholder that has registration rights agreed not to sell or otherwise dispose of any securities without the prior written consent of the underwriters for a period of 180 days after the date of this prospectus, subject to certain terms and conditions and early release of certain holders in specified circumstances. See the section titled “Underwriters” for more information regarding such restrictions.

After the completion of this offering, the holders of approximately 13,774,413 shares of our common stock will be entitled to certain demand registration rights. Six months after the completion of this offering, the holders of at least 20% of these shares, or a lesser percentage if the registration covers at least that number of shares with an anticipated gross offering price of at least $10.0 million, then outstanding can request that we register the offer and sale of their shares. If we determine that it would be seriously detrimental to our stockholders to effect such a demand registration, we have the right to defer such registration, not more than once in any 12-month period, for a period of up to 90 days. Additionally, we will not be required to effect a demand registration during the period beginning with 60 days prior to our good faith estimate of the date of the filing of, and ending 180 days following the effectiveness of, a registration statement relating to the public offering of our common stock.

After the completion of this offering, if we propose to register the offer and sale of our common stock under the Securities Act, in connection with the public offering of such common stock the holders of up to approximately 18,206,604 shares of our common stock will be entitled to certain “piggyback” registration rights allowing the holders to include their shares in such registration, subject to certain marketing and other limitations. As a result, whenever we propose to file a registration statement under the Securities Act, other than with respect to (1) a registration related to a company stock plan and (2) a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the public offering of our common stock, the holders of these shares are entitled to notice of the registration and have the right, subject to certain limitations, to include their shares in the registration.

After the completion of this offering, the holders of up to approximately 13,774,413 shares of our common stock may make a written request that we register the offer and sale of their shares on a registration statement on Form S-3 if we are eligible to file a registration statement on Form S-3 so long as the request covers at least that number of shares with an anticipated offering price, net of underwriting discounts and commissions, of at least $1.0 million. These stockholders may make an unlimited number of requests for registration on Form S-3; however, we will not be required to effect a registration on Form S-3 if we have effected one such registration within the 12 month period preceding the date of the request. Additionally, if we determine that it would be seriously detrimental to our stockholders to effect such a registration, we have the right to defer such registration, not more than once in any 12-month period, for a period of up to 90 days.

The provisions of Delaware law, our amended and restated certificate of incorporation and our amended and restated bylaws, which are summarized below, may have the effect of delaying, deferring, or discouraging another person from acquiring control of our company. They are also designed, in part, to encourage persons seeking to acquire control of us to negotiate first with our board of directors. We believe that the benefits of

increased protection of our potential ability to negotiate with an unfriendly or unsolicited acquirer outweigh the disadvantages of discouraging a proposal to acquire us because negotiation of these proposals could result in an improvement of their terms.

We are governed by the provisions of Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a public Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. A “business combination” includes mergers, asset sales, or other transactions resulting in a financial benefit to the stockholder. An “interested stockholder” is a person who, together with affiliates and associates, owns, or within three years did own, 15% or more of the corporation’s outstanding voting stock. These provisions may have the effect of delaying, deferring, or preventing a change in our control.

Amended and Restated Certificate of Incorporation and Amended and Restated Bylaw Provisions

Our restated certificate of incorporation and our restated bylaws include a number of provisions that could deter hostile takeovers or delay or prevent changes in control of our board of directors or management team, including the following:

Upon the completion of this offering, the transfer agent and registrar for our common stock will be Computershare Trust Company, N.A. The transfer agent and registrar’s address is 250 Royall Street, Canton, Massachusetts 02021.

Our common stock has been approved for listing on the New York Stock Exchange under the symbol “TRLA.”

Prior to this offering, there has been no public market for our common stock, and we cannot predict the effect, if any, that market sales of shares of our common stock or the availability of shares of our common stock for sale will have on the market price of our common stock prevailing from time to time. Future sales of our common stock in the public market, or the availability of such shares for sale in the public market, could adversely affect market prices prevailing from time to time. As described below, only a limited number of shares will be available for sale shortly after this offering due to contractual and legal restrictions on resale. Nevertheless, sales of our common stock in the public market after such restrictions lapse, or the perception that those sales may occur, could adversely affect the prevailing market price at such time and our ability to raise equity capital in the future.

Following the completion of this offering, based on the number of shares of our capital stock outstanding as of June 30, 2012, and after giving effect to the issuance of 89,100 shares of common stock to be acquired by certain selling stockholders through option exercises at the closing of this offering in order to sell those shares in this offering, we will have a total of 26,376,654 shares of our common stock outstanding. Of these outstanding shares, all of the 6,000,000 shares of common stock sold in this offering will be freely tradable, except that any shares purchased in this offering by our affiliates, as that term is defined in Rule 144 under the Securities Act, would only be able to be sold in compliance with the Rule 144 limitations described below.

The remaining outstanding shares of our common stock will be deemed “restricted securities” as defined in Rule 144. Restricted securities may be sold in the public market only if they are registered or if they qualify for an exemption from registration under Rule 144 or Rule 701 under the Securities Act, which rules are summarized below. In addition, all of our executive officers, directors, and holders of substantially all of our common stock and securities convertible into or exchangeable for our common stock have entered into market standoff agreements with us or lock-up agreements with the underwriters under which they have agreed, subject to specific exceptions, not to sell any of our stock for at least 180 days following the date of this prospectus, subject to early release in certain circumstances as described below. As a result of these agreements and the provisions of our investor rights agreement described above under the section titled “Description of Capital Stock—Registration Rights,” subject to the provisions of Rule 144 or Rule 701, shares will be available for sale in the public market as follows:

We, the selling stockholders, our executive officers, directors, and holders of substantially all of our common stock and securities convertible into or exchangeable for our common stock, have agreed or will agree that, subject to certain exceptions, for a period of 180 days from the date of this prospectus, we and they will not, without the prior written consent of J.P. Morgan Securities LLC and Deutsche Bank Securities Inc., dispose of or

hedge any shares or any securities convertible into or exchangeable for shares of our capital stock. J.P. Morgan Securities LLC and Deutsche Bank Securities Inc. may, in their discretion, and with the company’s consent, release any of the securities subject to these lock-up agreements at any time.

If, however, at any time beginning 90 days after the date of this prospectus (i) we have filed with the Securities and Exchange Commission at least one quarterly report on Form 10-Q or annual report on Form 10-K and (ii) the reported last sale price of our common stock on the New York Stock Exchange is at least 40% greater than the offering price per share set forth on the cover of this prospectus for 20 out of any 30 trading days ending on or after the 90th day after the date of this prospectus (which 30-trading day period may begin prior to such 90th day), including the last day of such 30-trading day period, then 25% of each holder’s shares of our common stock that are subject to the 180-day restrictions described above will be released from these restrictions immediately prior to the opening of the New York Stock Exchange on the day following the end of the 30-trading day period. We refer to this date as the initial release date, and we refer to any release between the initial release date and the date that is 180 days from the date of this prospectus as an early release. Further, if (1) during the last 17 days of the 180-day restricted period or the last 17-day period prior to the initial release date, we issue an earnings release or material news or a material event relating to our company occurs; or (2) prior to the initial release date or the expiration of the 180-day restricted period, we announce that we will release earnings results during the 16-day period beginning on the initial release date or the last day of the 180-day restricted period, then the initial release date will be deferred or the 180-day restricted period will be extended, as applicable, until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event; provided that no such extension shall apply from and after such date, if any, as the Financial Industry Regulatory Authority, Inc. shall have publicly announced that Rule 2711(f)(4) is no longer applicable with respect to any public offering (or any public offering with the same characteristics as this offering); and provided, further, that no such extension shall apply at any time beginning on or after December 10, 2012 until the close of trading on the New York Stock Exchange on December 31, 2012.

The lock-up agreements between each of our executive officers and the underwriters do not contain the opportunity for an early release of shares set forth in the preceding paragraph.

In general, under Rule 144 as currently in effect, once we have been subject to the public company reporting requirements of Section 13 or Section 15(d) of the Exchange Act for at least 90 days, a person who is not deemed to have been one of our affiliates for purposes of the Securities Act at any time during the 90 days preceding a sale and who has beneficially owned the shares proposed to be sold for at least six months, including the holding period of any prior owner other than our affiliates, is entitled to sell those shares without complying with the manner of sale, volume limitation or notice provisions of Rule 144, subject to compliance with the public information requirements of Rule 144. If such a person has beneficially owned the shares proposed to be sold for at least one year, including the holding period of any prior owner other than our affiliates, then that person would be entitled to sell those shares without complying with any of the requirements of Rule 144.

In general, under Rule 144, as currently in effect, our affiliates or persons selling shares on behalf of our affiliates are entitled to sell upon expiration of the lock-up agreements described above, within any three-month period, a number of shares that does not exceed the greater of:

Sales under Rule 144 by our affiliates or persons selling shares on behalf of our affiliates are also subject to certain manner of sale provisions and notice requirements and to the availability of current public information about us.

Rule 701 generally allows a stockholder who purchased shares of our common stock pursuant to a written compensatory plan or contract and who is not deemed to have been an affiliate of our company during the immediately preceding 90 days to sell these shares in reliance upon Rule 144, but without being required to comply with the public information, holding period, volume limitation or notice provisions of Rule 144. Rule 701 also permits affiliates of our company to sell their Rule 701 shares under Rule 144 without complying with the holding period requirements of Rule 144. All holders of Rule 701 shares, however, are required by that rule to wait until 90 days after the date of this prospectus before selling those shares pursuant to Rule 701.

Pursuant to an investor rights agreement, the holders of up to 18,206,604 shares of our common stock (including shares issuable upon the conversion of our outstanding convertible preferred stock immediately prior to the completion of this offering), or their transferees, will be entitled to certain rights with respect to the registration of the offer and sale of those shares under the Securities Act. See the section titled “Description of Capital Stock—Registration Rights” for a description of these registration rights. If the offer and sale of these shares is registered, the shares will be freely tradable without restriction under the Securities Act, and a large number of shares may be sold into the public market.

We intend to file a registration statement on Form S-8 under the Securities Act to register all of the shares of common stock issued or reserved for issuance under our 2005 Plan and our 2012 Plan. We expect to file this registration statement as promptly as possible after the completion of this offering. Shares covered by this registration statement will be eligible for sale in the public market, subject to the Rule 144 limitations applicable to affiliates, vesting restrictions and any applicable lock-up agreements and market standoff agreements.

As of June 30, 2012, options to purchase a total of 3,429,470 shares of common stock pursuant to our 2005 Plan were outstanding (including 89,100 shares to be sold in this offering by certain selling stockholders upon the exercise of options), of which options to purchase 1,917,795 shares were exercisable, and no options were outstanding under our 2012 Plan. We intend to file a registration statement on Form S-8 under the Securities Act as promptly as possible after the completion of this offering to register shares that may be issued pursuant to our 2005 Plan and our 2012 Plan. The registration statement on Form S-8 is expected to become effective immediately upon filing, and shares covered by the registration statement will then become eligible for sale in the public market, subject to the Rule 144 limitations applicable to affiliates, vesting restrictions and any applicable lock-up agreements and market standoff agreements. See the section titled “Executive Compensation—Employee Benefit and Stock Plans” for a description of our equity incentive plans.

The following is a summary of the material U.S. federal income tax consequences of the ownership and disposition of our common stock to non-U.S. holders, but does not purport to be a complete analysis of all the potential tax considerations relating thereto. This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended, or the Code, Treasury regulations promulgated thereunder, administrative rulings and judicial decisions, all as of the date hereof. These authorities may be changed, possibly retroactively, so as to result in U.S. federal income tax consequences different from those set forth below. We have not sought any ruling from the Internal Revenue Service, or the IRS, with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS will agree with such statements and conclusions.

This summary also does not address the tax considerations arising under the laws of any non-U.S., state or local jurisdiction or under U.S. federal gift and estate tax laws, except to the limited extent set forth below. In addition, this discussion does not address tax considerations applicable to an investor’s particular circumstances or to investors that may be subject to special tax rules, including, without limitation:

In addition, if a partnership or entity classified as a partnership for U.S. federal income tax purposes holds our common stock, the tax treatment of a partner generally will depend on the status of the partner and upon the activities of the partnership. Accordingly, partnerships that hold our common stock, and partners in such partnerships, should consult their tax advisors.

You are urged to consult your tax advisor with respect to the application of the U.S. federal income tax laws to your particular situation, as well as any tax consequences of the purchase, ownership and disposition of our common stock arising under the U.S. federal estate or gift tax rules or under the laws of any state, local, non-U.S. or other taxing jurisdiction or under any applicable tax treaty.

For purposes of this discussion, you are a non-U.S. holder if you are any holder other than:

We have not made any distributions on our common stock. However, if we do make distributions on our common stock, those payments will constitute dividends for U.S. tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed both our current and our accumulated earnings and profits, they will constitute a return of capital and will first reduce your basis in our common stock, but not below zero, and then will be treated as gain from the sale of stock.

Any dividend paid to you generally will be subject to U.S. withholding tax either at a rate of 30% of the gross amount of the dividend or such lower rate as may be specified by an applicable income tax treaty. In order to receive a reduced treaty rate, you must provide us with an IRS Form W-8BEN or other appropriate version of IRS Form W-8 certifying qualification for the reduced rate. A non-U.S. holder of shares of our common stock eligible for a reduced rate of U.S. withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the IRS. If the non-U.S. holder holds the stock through a financial institution or other agent acting on the non-U.S. holder’s behalf, the non-U.S. holder will be required to provide appropriate documentation to the agent, which then will be required to provide certification to us or our paying agent, either directly or through other intermediaries.

Dividends received by you that are effectively connected with your conduct of a U.S. trade or business (and, if an income tax treaty applies, such dividends are attributable to a permanent establishment maintained by you in the U.S.), are includible in your gross income in the taxable year received, are exempt from such withholding tax. In order to obtain this exemption, you must provide us with an IRS Form W-8ECI or other applicable IRS Form W-8 properly certifying such exemption. Such effectively connected dividends, although not subject to withholding tax, are taxed at the same graduated rates applicable to U.S. persons, net of certain deductions and credits, subject to an applicable income tax treaty providing otherwise. In addition, if you are a corporate non-U.S. holder, dividends you receive that are effectively connected with your conduct of a U.S. trade or business may also be subject to a branch profits tax at a rate of 30% or such lower rate as may be specified by an applicable income tax treaty.

You generally will not be required to pay U.S. federal income tax on any gain realized upon the sale or other disposition of our common stock unless:

We believe that we are not currently and will not become a USRPHC. However, because the determination of whether we are a USRPHC depends on the fair market value of our U.S. real property relative to the fair market value of our other business assets, there can be no assurance that we will not become a USRPHC in the future. Even if we become a USRPHC, however, as long as our common stock is regularly traded on an established securities market, such common stock will be treated as U.S. real property interests only if you actually or constructively hold more than five percent of such regularly traded common stock at any time during the shorter of the five-year period preceding your disposition of, or your holding period for, our common stock.

If you are a non-U.S. holder described in the first bullet above, you will be required to pay tax on the net gain derived from the sale under regular graduated U.S. federal income tax rates, and a corporate non-U.S. holder described in the first bullet above also may be subject to the branch profits tax at a 30% rate, or such lower rate as may be specified by an applicable income tax treaty. If you are an individual non-U.S. holder described in the second bullet above, you will be required to pay a flat 30% tax on the gain derived from the sale, which tax may be offset by U.S. source capital losses for the year. You should consult any applicable income tax or other treaties that may provide for different rules.

Our common stock beneficially owned by an individual who is not a citizen or resident of the United States (as defined for U.S. federal estate tax purposes) at the time of their death will generally be includable in the decedent’s gross estate for U.S. federal estate tax purposes, unless an applicable estate tax treaty provides otherwise.

Generally, we must report annually to the IRS the amount of dividends paid to you, your name and address, and the amount of tax withheld, if any. A similar report will be sent to you. Pursuant to applicable income tax treaties or other agreements, the IRS may make these reports available to tax authorities in your country of residence.

Payments of dividends or of proceeds on the disposition of stock made to you may be subject to information reporting and backup withholding at a current rate of 28% (such rate scheduled to increase to 31% for payments made after December 31, 2012) unless you establish an exemption, for example, by properly certifying your non U.S. status on a Form W-8BEN or another appropriate version of IRS Form W-8. Notwithstanding the foregoing, backup withholding and information reporting may apply if either we or our paying agent has actual knowledge, or reason to know, that you are a U.S. person.

Backup withholding is not an additional tax; rather, the U.S. income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund or credit may generally be obtained from the IRS, provided that the required information is furnished to the IRS in a timely manner.

Recently Enacted Legislation Affecting Taxation of our Common Stock Held by or through Foreign Entities

Recently enacted legislation generally will impose a U.S. federal withholding tax of 30% on dividends, and the gross proceeds of a disposition of our common stock, paid after December 31, 2012 to a “foreign financial institution” (as specially defined under these rules), unless such institution enters into an agreement with the U.S. government to withhold on certain payments and to collect and provide to the U.S. tax authorities substantial information regarding the U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners). The legislation also generally will impose a U.S. federal withholding tax of 30% on dividends and the gross proceeds

of a disposition of our common stock paid after December 31, 2012 to a non-financial foreign entity unless such entity provides the withholding agent with a certification identifying the direct and indirect U.S. owners of the entity. Under certain circumstances, a non-U.S. holder might be eligible for refunds or credits of such taxes. Prospective investors are encouraged to consult with their own tax advisors regarding the possible implications of this legislation on their investment in our common stock.

The preceding discussion of U.S. federal tax considerations is for general information only. It is not tax advice. Each prospective investor should consult its own tax advisor regarding the particular U.S. federal, state and local and non-U.S. tax consequences of purchasing, holding and disposing of our common stock, including the consequences of any proposed change in applicable laws.

We and the selling stockholders are offering the shares of common stock described in this prospectus through a number of underwriters. J.P. Morgan Securities LLC and Deutsche Bank Securities Inc. are acting as joint book-running managers of the offering and as representatives of the underwriters. We and the selling stockholders expect to enter into an underwriting agreement with the underwriters. Subject to the terms and conditions of the underwriting agreement, we and the selling stockholders have severally agreed to sell to the underwriters, and each underwriter has severally agreed to purchase, at the public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus, the number of shares of common stock listed next to its name in the following table:

The underwriters are committed to purchase all the shares of common stock offered by us and the selling stockholders if they purchase any shares. The underwriting agreement will also provide that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the offering may be terminated.

The underwriters propose to offer the shares of common stock directly to the public at the initial public offering price set forth on the cover page of this prospectus and to certain dealers at that price less a concession not in excess of $ per share. Any such dealers may resell shares to certain other brokers or dealers at a discount of up to $ per share from the initial public offering price. After the initial public offering of the shares, the offering price and other selling terms may be changed by the underwriters. Sales of shares made outside of the United States may be made by affiliates of the underwriters.

The underwriters have an option to purchase up to 900,000 additional shares of common stock from us to cover sales of shares by the underwriters which exceed the number of shares specified in the table above. The underwriters have 30 days from the date of this prospectus to exercise this overallotment option. If any shares are purchased with this overallotment option, the underwriters will purchase shares in approximately the same proportion as shown in the table above. If any additional shares of common stock are purchased, the underwriters will offer the additional shares on the same terms as those on which the shares are being offered.

The underwriting fee is equal to the public offering price per share of common stock less the amount paid by the underwriters to us per share of common stock. The underwriting fee is $ per share. The following table shows the per share and total underwriting discounts and commissions to be paid to the underwriters by us and the selling stockholders, assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares.

We estimate that the total expenses of this offering that are payable by us, including registration, filing and listing fees, printing fees, and legal and accounting expenses, but excluding the underwriting discounts and commissions, will be approximately $4.0 million.

A prospectus in electronic format may be made available on the web sites maintained by one or more underwriters, or selling group members, if any, participating in the offering. The underwriters may agree to allocate a number of shares to underwriters and selling group members for sale to their online brokerage account holders. Internet distributions will be allocated by the representatives to underwriters and selling group members that may make Internet distributions on the same basis as other allocations.

We have agreed that we will not (i) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise dispose of, directly or indirectly, or file with the Securities and Exchange Commission a registration statement under the Securities Act of 1933 relating to, any shares of our common stock or securities convertible into or exchangeable or exercisable for any shares of our common stock, or publicly disclose the intention to make any offer, sale, pledge, disposition or filing, or (ii) enter into any swap or other arrangement that transfers all or a portion of the economic consequences associated with the ownership of any shares of common stock or any such other securities (regardless of whether any of these transactions are to be settled by the delivery of shares of common stock or such other securities, in cash or otherwise), in each case without the prior written consent of J.P. Morgan Securities LLC and Deutsche Bank Securities Inc. for a period of 180 days after the date of this prospectus, other than the shares of our common stock to be sold hereunder, any shares of our common stock issued upon the exercise of options granted under our equity incentive plans, and up to % of our common stock in connection with strategic transactions. Notwithstanding the foregoing, if (1) during the last 17 days of the 180-day restricted period, we issue an earnings release or material news or a material event relating to our company occurs; or (2) prior to the expiration of the 180-day restricted period, we announce that we will release earnings results during the 16-day period beginning on the last day of the 180-day period, the restrictions described above shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event; provided that no such extension shall apply from and after such date, if any, as the Financial Industry Regulatory Authority, Inc. shall have publicly announced that Rule 2711(f)(4) is no longer applicable with respect to any public offering (or any public offering with the same characteristics as this offering).

The selling stockholders, our executive officers, directors, and holders of substantially all of our common stock and securities convertible into or exchangeable for our common stock have entered into or will enter into lock-up agreements with the underwriters prior to the commencement of this offering pursuant to which each of these persons or entities, with limited exceptions set forth below, for a period of 180 days after the date of this prospectus, may not, without the prior written consent of J.P. Morgan Securities LLC and Deutsche Bank Securities Inc., (1) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of our common stock or any securities convertible into or exercisable or exchangeable for our common stock (including, without limitation, common stock or such other securities which may be deemed to be beneficially owned by such directors, executive officers, managers and members in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant) or (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the common stock or such

other securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of common stock or such other securities, in cash or otherwise, or (3) make any demand for or exercise any right with respect to the registration of any shares of our common stock or any security convertible into or exercisable or exchangeable for our common stock.

The lock-up agreements between each of our executive officers and the underwriters do not contain the opportunity for an early release of shares set forth in the preceding paragraph.

We and the selling stockholders have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933.

Our common stock has been approved for listing on the New York Stock Exchange under the symbol “TRLA.”

In connection with this offering, the underwriters may engage in stabilizing transactions, which involves making bids for, purchasing and selling shares of common stock in the open market for the purpose of preventing or retarding a decline in the market price of the common stock while this offering is in progress. These stabilizing transactions may include making short sales of the common stock, which involves the sale by the underwriters of a greater number of shares of common stock than they are required to purchase in this offering, and purchasing shares of common stock on the open market to cover positions created by short sales. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriters’ overallotment option referred to above, or may be “naked” shorts, which are short positions in excess of that amount. The underwriters may close out any covered short position either by exercising their overallotment option, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriters will consider, among other things, the price of shares available for purchase in the open market compared to the price at which the underwriters may purchase shares through the overallotment option. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriters create a naked short position, they will purchase shares in the open market to cover the position.

The underwriters have advised us that, pursuant to Regulation M of the Securities Act of 1933, they may also engage in other activities that stabilize, maintain or otherwise affect the price of the common stock, including the imposition of penalty bids. This means that if the representatives of the underwriters purchase common stock in the open market in stabilizing transactions or to cover short sales, the representatives can require the underwriters that sold those shares as part of this offering to repay the underwriting discount received by them.

These activities may have the effect of raising or maintaining the market price of the common stock or preventing or retarding a decline in the market price of the common stock, and, as a result, the price of the common stock may be higher than the price that otherwise might exist in the open market. If the underwriters commence these activities, they may discontinue them at any time. The underwriters may carry out these transactions on the New York Stock Exchange, in the over-the-counter market or otherwise.

Prior to this offering, there has been no public market for our common stock. The initial public offering price will be determined by negotiations between us and the representatives of the underwriters. In determining the initial public offering price, we and the representatives of the underwriters expect to consider a number of factors including:

Neither we, the selling stockholders, nor the underwriters can assure investors that an active trading market will develop for our common stock, or that the shares will trade in the public market at or above the initial public offering price.

Other than in the United States, no action has been taken by us or the underwriters that would permit a public offering of the securities offered by this prospectus in any jurisdiction where action for that purpose is required. The securities offered by this prospectus may not be offered or sold, directly or indirectly, nor may this prospectus or any other offering material or advertisements in connection with the offer and sale of any such securities be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction. Persons into whose possession this prospectus comes are advised to inform themselves about and to observe any restrictions relating to the offering and the distribution of this prospectus. This prospectus does not constitute an offer to sell or a solicitation of an offer to buy any securities offered by this prospectus in any jurisdiction in which such an offer or a solicitation is unlawful.

This prospectus has not been registered as a prospectus with the Monetary Authority of Singapore. Accordingly, this prospectus and any other document or material in connection with the offer or sale, or invitation for subscription or purchase, of the shares may not be circulated or distributed, nor may the shares be offered or sold, or be made the subject of an invitation for subscription or purchase, whether directly or indirectly, to persons in Singapore other than (i) to an institutional investor under Section 274 of the Securities and Futures Act, Chapter 289 of Singapore, or the SFA, (ii) to a relevant person, or any person pursuant to Section 275(1A), and in accordance with the conditions, specified in Section 275 of the SFA or (iii) otherwise pursuant to, and in accordance with the conditions of, any other applicable provision of the SFA.

This document, as well as any other material relating to the shares of our common stock, which are the subject of the offering contemplated by this prospectus, does not constitute an issue prospectus pursuant to Article 652a of the Swiss Code of Obligations.

We have audited the accompanying balance sheets of Trulia, Inc. (the “Company”) as of December 31, 2010 and 2011, and the related statements of operations, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2011. Our audits also included the financial statement schedule listed in Part II, Item 16. These financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material respects, the financial position of Trulia, Inc. as of December 31, 2010 and 2011, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2011, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic financial statements taken as a whole, present fairly, in all material respects, the information set forth therein.

Trulia, Inc. (“Trulia” or the “Company”) was incorporated on June 1, 2005 in the state of Delaware as Realwide, Inc. On September 22, 2005, the Company changed its name to Trulia, Inc. Trulia’s online marketplace and mobile applications help consumers research homes and neighborhoods and help real estate professionals market themselves and their listings. The Company’s subscription products also provide real estate professionals with access to transaction-ready consumers and help them enhance their online presence.

The Company operates in a dynamic industry and, accordingly, can be affected by a variety of factors. For example, management of the Company believes that changes in any of the following areas could have a significant negative effect on the Company in terms of its future financial position, results of operations, or cash flows: ability to obtain additional financing; advances and trends in new technologies and industry standards; changes in certain strategic relationships or customer relationships; market acceptance of the Company’s products; development of sales channels; loss of significant customers; litigation or other claims against the Company; the hiring, training, and retention of key employees; and new product introductions by competitors.

The Company’s financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

The preparation of the accompanying financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events that affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Significant items subject to such estimates include: revenue recognition; allowance for doubtful accounts; the useful lives of property and equipment; the recoverability of long-lived assets; the determination of fair value of the Company’s common stock, stock options and preferred and common stock warrants; income tax uncertainties, including a valuation allowance for deferred tax assets; and contingencies. The Company bases these estimates on historical and anticipated results, trends and various other assumptions that the Company believes are reasonable under the circumstances, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities and recorded revenue and expenses that are not readily apparent from other sources. Actual results could differ from those estimates.

The accompanying balance sheet as of June 30, 2012, the statements of operations and the statements of cash flows for the six months ended June 30, 2011 and 2012 and the statement of stockholders’ deficit for the six months ended June 30, 2012 are unaudited. The unaudited interim financial statements have been prepared on the same basis as the annual financial statements and reflect, in the opinion of management, all adjustments of normal, recurring nature that are necessary for the fair presentation of the Company’s financial position as of June 30, 2012 and results of operations and cash flows for the six months ended June 30, 2011 and 2012. The financial data and other information disclosed in these notes to the financial statements related to the three-month periods are unaudited. The results of the six months ended June 30, 2012 are not necessarily indicative of the results to be expected for the year ending December 31, 2012 or for any other interim period or for any other future year.

Immediately prior to the completion of the Company’s initial public offering (“IPO”), all of the outstanding shares of convertible preferred stock will automatically convert into shares of common stock. The June 30, 2012 unaudited pro forma stockholders’ equity has been prepared assuming the conversion of the convertible preferred stock outstanding into 14,161,444 shares of common stock, and the resulting reclassification of the preferred stock warrant liability to additional paid-in capital.

Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, short-term investments and trade accounts receivable. The Company deposits its cash and cash equivalents and short-term investments with major financial institutions that management believes are of high credit quality; however, at times, balances exceed federally insured limits.

The Company’s accounts receivable are derived from customers in the United States of America. The Company does not require its customers to provide collateral to support accounts receivable. The Company performs ongoing credit evaluations of its customers’ financial condition and maintains allowances for estimated credit losses. Actual credit losses may differ from the Company’s estimates. Revenue from one customer represented approximately 19% of the Company’s total revenue during the year ended December 31, 2009. No customer represented 10% or more of total revenue during the years ended December 31, 2010, 2011 and six months ended June 30, 2011 and 2012. No customer accounted for 10% or more of the Company’s gross accounts receivable as of December 31, 2010 and 2011 and June 30, 2012.

The Company’s revenue is derived from selling subscription products to real estate professionals and from display advertising sold to brand advertisers that operate in the real estate ecosystem. The Company recognizes revenue when (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred or services have been rendered to the customer, (iii) the fee is fixed or determinable, and (iv) collectability is reasonably assured. The Company considers a signed agreement, a binding insertion order or other similar documentation reflecting the terms and conditions under which products will be provided to be persuasive evidence of an arrangement. Collectability is assessed based on a number of factors, including payment history and the creditworthiness of a customer. If it is determined that collection is not reasonably assured, revenue is not recognized until collection becomes reasonably assured, which is generally upon receipt of cash. The Company does not request collateral from its customers.

Marketplace revenues consist primarily of subscription-based revenue. The fixed-fee subscription-based revenue is recognized ratably over the period service is provided.

Media revenues primarily consist of advertising sales on a cost per thousand impressions (“CPM”) or cost per click (“CPC”) basis to advertisers. The Company recognizes these revenues in the period the clicks or impressions are delivered to the client.

The Company enters into arrangements with customers that include combinations of CPC or CPM media placements and subscription products.

For the years ended December 31, 2009 and 2010, because the Company had not yet established the fair value for each element, advertising revenue was recognized ratably over the contract term.

Beginning on January 1, 2011, the Company adopted new authoritative guidance on multiple-element arrangements, using the prospective method for all arrangements entered into or materially modified from the date of adoption. Under this new guidance, the Company allocates arrangement consideration in multiple-element revenue arrangements at the inception of an arrangement to all deliverables or those packages in which all components of the package are delivered at the same time, based on the relative selling price method in accordance with the selling price hierarchy, which includes: (i) vendor-specific objective evidence (“VSOE”) if available; (ii) third-party evidence (“TPE”) if VSOE is not available, and (iii) best estimate of selling price (“BESP”) if neither VSOE nor TPE is available.

VSOE- The Company determines VSOE based on its historical pricing and discounting practices for the specific product when sold separately. In determining VSOE, the Company requires that a substantial majority of the standalone selling prices for these products fall within a reasonably narrow pricing range. For certain subscription products, the Company has been able to establish VSOE.

TPE- When VSOE cannot be established for deliverables in multiple-element arrangements, the Company applies judgment with respect to whether it can establish a selling price based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. Generally, the Company’s go-to-market strategy differs from that of its peers and its offerings contain a significant level of differentiation such that the comparable pricing of the products cannot be obtained. Furthermore, the Company is unable to reliably determine what similar competitor selling prices are on a standalone basis. As a result, the Company has not been able to establish selling price based on TPE.

BESP- When it is unable to establish selling price using VSOE or TPE, the Company uses BESP in its allocation of arrangement consideration. The objective of BESP is to determine the price at which the Company would transact a sale if the service were sold regularly on a standalone basis. As the Company has not been able to establish VSOE or TPE for CPM and CPC products and certain subscription products, the Company determines BESP for these deliverables based on the following:

The Company limits the amount of allocable arrangement consideration to amounts that are fixed or determinable and that are not contingent on future performance or future deliverables. The Company regularly reviews BESP. Changes in assumptions or judgments or changes to the elements in the arrangement could cause a material increase or decrease in the amount of revenue that the Company reports in a particular period.

The Company recognizes the relative fair value of the products as they are delivered assuming all other revenue recognition criteria are met. As a result of implementing this recent authoritative guidance, the Company’s revenue for the twelve months ended December 31, 2011 was not materially different from what would have been recognized under the previous guidance for multiple-element arrangements.

Cost of revenue consists primarily of expenses related to operating the Company’s website and mobile applications, including those associated with the operation of the Company’s data center, hosting fees, customer service related headcount expenses including salaries, bonuses, benefits and stock-based compensation expense, licensed content, credit card fees, third-party contractor fees and other allocated overhead.

Costs to research and develop the Company’s products are expensed as incurred. These costs consist primarily of technology and development headcount related expenses including salaries, bonuses, benefits and stock-based compensation expense, third-party contractor fees and allocated overhead primarily associated with developing new technologies. Technology and development also includes amortization of capitalized costs (“Product Development Cost”) associated with the development of the Company’s marketplace.

Product Development Cost include costs related to the development of the Company’s marketplace which is inclusive of costs related to the development of the Company’s delivery points, the website and mobile applications. Product Development Cost are accounted for as follows: all costs incurred in the preliminary project and post-implementation stages are expensed as incurred while certain costs incurred in the application development stage of a new product or projects to provide significant additional functionality to existing products are capitalized if certain criteria are met. Maintenance and enhancement costs are typically expensed as incurred. The Company capitalized costs associated with product development of $58,000, $851,000, $1.3 million and $788,000 during the years ended December 31, 2009, 2010, 2011 and six months ended June 30, 2012, and recorded related amortization expenses of $179,000, $366,000, $708,000, $264,000 and $481,000 during the years ended December 31, 2009, 2010, 2011 and six months ended June 30, 2011 and 2012. The net book value of capitalized product development costs was $571,000, $1.1 million and $1.4 million as of December 31, 2010 and 2011 and June 30, 2012. Such costs are amortized on a straight-line basis over the estimated useful lives of the related assets, which has been estimated to be two years. Amortization expense is included in technology and development in the statements of operations.

Advertising costs are expensed when incurred and are included in sales and marketing expenses in the accompanying statements of operations. The Company’s advertising expenses were $275,000, $127,000, $459,000, $133,000 and $1.3 million during the years ended December 31, 2009, 2010, 2011 and six months ended June 30, 2011 and 2012.

The Company recognizes compensation costs related to stock options granted to employees based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures. The Company estimates the grant date fair value of option grants, and the resulting stock-based compensation expense, using the Black-Scholes option-pricing model. The grant date fair value of the stock-based awards is recognized on a straight-line basis over the requisite service period, which is the vesting period of the respective awards.

The Company accounts for stock options issued to nonemployees based on the fair value of the awards determined using the Black-Scholes option-pricing model. The fair value of stock options granted to nonemployees are remeasured as the stock options vest, and the resulting change in value, if any, is recognized in the statement of operations during the period the related services are rendered.

The Company accounts for income taxes in accordance with the liability method. Under this method, deferred tax assets and liabilities are measured based on differences between the financial reporting and the tax bases of assets and liabilities using enacted tax rates that are expected to be in effect when the differences are expected to reverse. A valuation allowance is established to reduce net deferred tax assets to amounts that are more likely than not to be realized.

The Company accounts for uncertainty in tax positions recognized in the financial statements by recognizing a tax benefit from an uncertain tax position when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. Income tax positions must meet a more-likely-than-not recognition threshold at the effective date to be recognized.

The Company’s policy for classifying interest and penalties associated with unrecognized income tax benefits is to include such items as tax expense.

During the years ended December 31, 2009, 2010, 2011 and six months ended June 30, 2011 and 2012, the Company did not have any other comprehensive income and, therefore, the net loss and comprehensive loss was the same for all periods presented.

Net Loss and Pro Forma Net Loss per Share Attributable to Common Stockholders

The Company calculates its basic and diluted net loss per share attributable to common stockholders in conformity with the two-class method required for companies with participating securities. Under the two-class method, in periods when the Company has net income, net income attributable to common stockholders is determined by allocating undistributed earnings, calculated as net income less current period convertible preferred stock non-cumulative dividends, between common stock and the convertible preferred stock. In computing diluted net income attributable to common stockholders, undistributed earnings are re-allocated to reflect the potential impact of dilutive securities. The Company’s basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding for the period. The diluted net loss per share attributable to common stockholders is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. For purposes of this calculation, convertible preferred stock, options to purchase common stock, preferred stock warrants and common stock warrants are considered common stock equivalents but have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is antidilutive. In contemplation of an initial public offering, the Company has presented the unaudited pro forma basic and diluted net loss per share attributable to common stockholders, which has been computed to give effect to the automatic conversion of the convertible preferred stock into shares of common stock as of the beginning of the respective period.

Cash and cash equivalents include cash and highly liquid investments with original maturities of three months or less at the time of acquisition. As of December 31, 2010 and 2011 and June 30, 2012, cash and cash equivalents consist of cash and money market funds. All credit card and debit card transactions that process within one business day are also classified as cash and cash equivalents. The amounts due from third-party merchant processors for these transactions classified as cash totaled $7,000, $207,000 and $325,000 as of December 31, 2010 and 2011 and June 30, 2012.

The Company’s short-term investments consist of certificates of deposit with maturities of 12 months or less from the balance sheet date. Short-term investments are reported at cost, which approximates fair value, as of each balance sheet date.

Restricted cash consists of certificates of deposit with a major financial institution. The Company had loans with this financial institution as of December 31, 2010 which required the certificates of deposit to be held as collateral for the loans. Upon repayment of the loans during the year ended December 31, 2011, these restrictions were released and the Company no longer had any restricted cash.

The Company performs ongoing credit evaluations of its customers. Accounts receivable are recorded at invoiced amounts, net of the Company’s estimated allowances for doubtful accounts. The allowance for doubtful accounts is estimated based on an assessment of the Company’s ability to collect on customer accounts receivable. The Company regularly reviews the allowance by considering certain factors such as historical experience, industry data, credit quality, age of accounts receivable balances and current economic conditions that may affect a customer’s ability to pay. In cases where the Company is aware of circumstances that may impair a specific customer’s ability to meet their financial obligations, the Company records a specific allowance against amounts due from the customer and thereby reduces the net recognized receivable to the amount the Company reasonably believes will be collected. The Company writes-off accounts receivable against the allowance when it determines the balance is uncollectible and no longer actively pursues collection of the receivable. Write-offs of accounts receivable to bad debt expense were $94,000, $82,000, $176,000, $68,000 and $51,000 during the years ended December 31, 2009, 2010, and 2011 and six months ended June 30, 2011 and 2012.

Deferred offering costs which consist of direct incremental legal and accounting fees relating to the IPO, are capitalized. The deferred offering costs will be offset against IPO proceeds upon the consummation of the offering. In the event the offering is terminated, deferred offering costs will be expensed. As of June 30, 2012, the Company capitalized $2.1 million of deferred offering costs in other assets on the balance sheet. No amounts were deferred as of December 31, 2011.

Property and equipment are initially recorded at cost and depreciated using a straight-line method over the estimated useful lives of the assets. Maintenance and repair costs are charged to expense as incurred. The useful lives of the Company’s property and equipment are as follows:

Depreciation expense of assets acquired through capital leases is included in depreciation and amortization expense in the statements of operations.

Goodwill represents the excess of the aggregate purchase price paid over the fair value of the net tangible assets acquired. Goodwill is not amortized and is tested for impairment at least annually or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The Company has determined that it operates as one reporting unit and has selected December 1 as the date to perform its annual impairment test. In the valuation of its goodwill, the Company must make assumptions regarding estimated future cash flows to be derived from the Company. If these estimates or their related assumptions change in the future, the Company may be required to record impairment for these assets. The first step of the impairment test involves comparing the fair value of the reporting unit to its net book value, including goodwill. If the net book value exceeds its fair value, then the Company would perform the second step of the goodwill impairment test to determine the amount of the impairment loss. The impairment loss would be calculated by comparing the implied fair value of the Company to its net book value. In calculating the implied fair value of the Company’s goodwill, the fair value of the Company would be allocated to all of the other assets and liabilities based on their fair values. The excess of the fair value of the Company over the amount assigned to its other assets and liabilities is the implied fair value of goodwill. An impairment loss would be recognized when the carrying amount of goodwill exceeds its implied fair value. The Company was not required to perform the second step of the goodwill impairment test during the years ended December 31, 2010 or 2011. There was no impairment of goodwill recorded for the years ended December 31, 2010 or 2011.

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is measured first by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, an impairment loss would be recognized when the carrying amount of the asset exceeds the fair value of the asset. To date, the Company believes that no such impairment has occurred.

The carrying values of the Company’s financial instruments, including cash equivalents, short-term investments, accounts receivable and accounts payable, approximated their fair values due to the short period of time to maturity or repayment. The carrying amount for the Company’s preferred stock warrants represent their fair value. Long-term debt is stated at the carrying value as the stated interest rate approximates market rates currently available to the Company. The carrying value of the notes payable approximates fair value principally because of the short-term nature of this liability. Fair value is defined as the exchange price that would be received for an asset or an exit price paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The current accounting guidance for fair value measurements defines a three-level valuation hierarchy for disclosures as follows:

Level I—Unadjusted quoted prices in active markets for identical assets or liabilities;

Level II—Inputs other than quoted prices included within Level I that are observable, unadjusted quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data; and

Level III—Unobservable inputs that are supported by little or no market activity, which requires the Company to develop its own assumptions.

The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company’s financial instruments consist of Level I assets and Level III liabilities. Level I assets include highly liquid money market funds that are included in cash and cash equivalents and certificates of deposit that are included as short-term investments. Level III liabilities consist of the preferred stock warrant liability. The fair values of the outstanding preferred stock warrants are measured using a Monte Carlo model. Inputs used to determine the estimated fair value of the warrant liability include the estimated fair value of the underlying stock at the valuation date, the estimated term of the warrants, risk-free interest rates, expected dividends and the expected volatility of the underlying stock.

Deferred revenue consists of prepaid but unrecognized subscription revenue, advertising fees received or billed in advance of delivery and for amounts received in instances when revenue recognition criteria has not been met. Deferred revenue is recognized when all revenue recognition criteria have been met.

The Company’s warrants to purchase convertible preferred stock are classified as liabilities on the balance sheets at fair value upon issuance because these warrants contain certain anti-dilution provisions which require the Company to lower the exercise price of the warrants upon any future down-round financings. Therefore, the warrants are subject to remeasurement to fair value at each balance sheet date, and any change in fair value is recognized in the statements of operations. At the time of issuance, the aggregate fair value of these warrants were determined using a Monte Carlo model. The Company will continue to adjust the liability for changes in fair value using a Monte Carlo model until the earlier of the exercise or expiration of the warrants, the conversion of the underlying shares of convertible preferred stock, or the completion of a liquidation event, including the

completion of an IPO. Upon exercise or expiration of the warrants or the conversion of the underlying preferred stock, the related warrant liability will be remeasured to fair value and any remaining liability will be reclassified to additional paid-in capital.

The Company’s chief operating decision maker is its chief executive officer. The chief executive officer reviews financial information accompanied by information about revenue by product line for purposes of allocating resources and evaluating financial performance. The Company has one business activity and there are no segment managers who are held accountable for operations, or operating results for levels or components. In addition, the Company’s operation and customers are located only in the United States of America. Accordingly, the Company has a single reporting segment and operating unit structure.

Under the Jumpstart Our Business Startups Act (“JOBS Act”), the Company meets the definition of an emerging growth company. The Company has irrevocably elected to opt out of the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act.

In January 2010, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2010-06, Improving Disclosures about Fair Value Measurements (Topic 820)—Fair Value Measurements and Disclosures, which requires additional disclosures about the different classes of assets and liabilities measured at fair value, the valuation techniques and inputs used, and the activity in Level III fair value measurements. This guidance was effective for interim and annual reporting periods beginning after December 15, 2009, except for certain Level III activity disclosure requirements that became effective for reporting periods beginning after December 15, 2010. Accordingly, the Company adopted this new guidance beginning January 1, 2010, except for the additional Level III requirements, which were adopted beginning January 1, 2011. Level III assets and liabilities are those whose fair value inputs are unobservable and reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. The adoption of this guidance required additional disclosures but did not have a material impact on the Company’s results of operations or financial position.

In May 2011, the FASB issued ASU No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (“IFRS”). This pronouncement was issued to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and IFRS. ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for Level III fair value measurements. This pronouncement is effective for reporting periods beginning on or after December 15, 2011, with early adoption prohibited. The Company adopted this standard in January 2012 as reflected in Note 3 of these financial statements.

In June 2011, the FASB issued ASU No. 2011-05, Presentation of Comprehensive Income, which requires an entity to present total comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements and eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. The Company early adopted this guidance on January 1, 2012, retrospectively. During the years ended December 31, 2009, 2010, 2011 and six months ended June 30, 2011 and 2012, the Company did not have any other comprehensive income and, therefore, the net loss and comprehensive loss was the same for all periods presented.

In September 2011, the FASB issued ASU No. 2011-08, Intangibles—Goodwill and Other (Topic 350). The amended guidance will allow companies to assess qualitative factors to determine if it is more-likely-than-not that goodwill might be impaired and whether it is necessary to perform the two-step goodwill impairment test

required. This pronouncement is effective for fiscal years beginning after December 15, 2011. The Company adopted this standard on January 1, 2012. The adoption of this accounting standard update does not have any material impact on the Company’s results of operations or financial position.

The Company measures and reports its cash equivalents, short-term investments and preferred stock warrant liability at fair value on a recurring basis. The Company’s cash equivalents and short-term investments are invested in money market funds and certificates of deposit. The following table sets forth the fair value of the Company’s financial assets and liabilities remeasured on a recurring basis, by level within the fair value hierarchy (in thousands):

None of the cash equivalents or short-term investments held by the Company had unrealized losses and there were no realized losses for the year ended December 31, 2011 and the six months ended June 30, 2012. There were no other-than-temporary impairments for these instruments as of December 31, 2011 or June 30, 2012. As of December 31, 2011 and June 30, 2012, the contractual maturity of all certificates of deposit was less than one year.

Level III instruments consist solely of the Company’s preferred stock warrant liability in which the fair value was measured using a Monte Carlo model. The significant unobservable inputs used in the fair value measurement of the preferred stock warrant liability are the fair value of the underlying stock at the valuation date and the estimated term of the warrants. Generally, increases (decreases) in the fair value of the underlying stock and estimated term would result in a directionally similar impact to the fair value measurement.

The following table sets forth a summary of the changes in the fair value of the Company’s Level III financial liabilities for the year ended December 31, 2011 and six months ended June 30, 2012 (in thousands):

The gains and losses from remeasurement of Level III financial liabilities are recorded through the change in fair value of warrant liability in the statements of operations.

As of December 31, 2010, 2011 and June 30, 2012, property and equipment under capital lease, included under computer equipment above, amounted to $245,000, $729,000 and $795,000 with accumulated depreciation of $48,000, $215,000 and $338,000. Depreciation and amortization expense during the years ended December 31, 2009, 2010, and 2011 and the six months ended June 30, 2011 and 2012 was $855,000, $963,000, $2.5 million, $1.0 million and $1.6 million.

On December 10, 2010, the Company entered into an Agreement of Plan of Merger (“Movity Agreement”) to acquire Movity, Inc. (“Movity”), a privately held geographic data company which was founded in January 2010. The acquisition, which closed on December 10, 2010, allowed the Company to enhance its workforce.

Upon the closing of the acquisition, all of the outstanding shares of Movity, including the shares of common stock that were issued by Movity upon the closing of the acquisition as a result of the automatic conversion of its convertible promissory note into common stock, were converted into the right to receive a fraction of a share of the Company’s common stock. The Company accounted for the Movity acquisition as the purchase of a business. The Company expensed the related acquisition costs, consisting primarily of legal expenses in the amount of $155,000, during the year ended December 31, 2010. These legal expenses are presented as general and administrative expense in the statement of operations for the year ended December 31, 2010. The total purchase consideration of $2.2 million consisted of the issuance of 542,689 shares of the Company’s common stock with fair value of $4.0866 per share. Under the terms of the Movity Agreement, the Company is entitled to withhold 125,461 shares of the total purchase consideration as partial security for indemnification of obligations of Movity’s stockholders. The shares withheld will be released as follows: (i) 75% of the shares will be released on the 18-month anniversary of the acquisition date, and (ii) the remaining shares will be released on April 15, 2014. Upon the completion of the acquisition, the operations were absorbed by the Company, and Movity ceased to exist as a separate entity. During the six months ended June 30, 2012, 3,343 shares were returned from escrow as indemnification from Movity’s stockholders. In addition, the Company also released 75% of the remaining shares, or 91,594 shares, in accordance with the Movity Agreement.

The following table summarizes the fair value of assets acquired and liabilities assumed (in thousands):

The excess of the consideration transferred over the fair value assigned to the assets acquired and liabilities assumed was $2.2 million, which represents the goodwill resulting from the acquisition. Goodwill is attributable to technological expertise associated with the acquired assembled workforce. None of the goodwill is expected to be deductible for income tax purposes. The Company tests goodwill for impairment on an annual basis on December 1, or sooner if deemed necessary. As of December 31, 2010, 2011 and June 30, 2012, there was no impairment of goodwill.

Supplemental information on an unaudited pro forma basis is presented below for the year ended December 31, 2010 (in thousands):

The Company did not present comparative information for the year ended December 31, 2009 above as Movity was founded in January 2010. The unaudited pro forma combined financial information includes the results of the Company and Movity as if the acquisition of Movity had occurred as of January 1, 2010. The pro forma information presented does not purport to present what the actual results would have been had the acquisition actually occurred on January 1, 2010, nor is the information intended to project results for any future period. Further, the unaudited pro forma information excludes any benefits that may result from the acquisition due to synergies that were derived from the elimination of duplicative costs. From the acquisition date through December 31, 2010, the Company recognized an immaterial loss from the Movity acquisition in the accompanying statements of operations.

In September 2008, the Company entered into a term loan agreement with a banking institution for a principal amount of $725,000. The loan carried a variable annual interest rate floating at London Interbank Offered Rate (“LIBOR”) plus 2% and matured in July 2011. In April 2009, the Company repaid the outstanding balance of the loan and concurrently entered into a new loan agreement with the same banking institution for a principal amount of $776,000. The new loan carried the same interest rate as the original loan and the principle was repayable over 27 equal monthly installments. The Company repaid the new loan on its maturity date in July 2011.

From January 2010 through April 2011, the Company entered into several additional loan agreements with the same banking institution for a total principal of $4.3 million. These loans carried variable annual interest rates floating at 1.25 - 2% above LIBOR, were repayable in 31 or 36 equal monthly installments, and had maturity dates from January 2013 through April 2014. In September 2011 when the outstanding principal for these loans was $3.0 million, the Company repaid the loans with the proceeds received from the loan facility agreement discussed immediately below. These loan agreements had prepayment penalties and required additional interest upon prepayment. The Company recognized an immaterial loss upon the repayment of the debt prior to its contractual maturity.

In September 2011, the Company entered into a $20.0 million loan and security agreement which provided for a secured term loan facility (“Credit Facility”), issuable in tranches, with a financial institution. This financial institution was not the same banking institution noted in the preceding paragraph, therefore, the issuance of the Credit Facility did not result in a modification to the prior debt agreements. Under the Credit Facility, the first tranche of $5.0 million was drawn down in full in September 2011 and was used to repay the Company’s outstanding debt. The second tranche of $5.0 million was also drawn down in full in September 2011. As of December 31, 2011 and June 30, 2012, the Company had not drawn down the third tranche of the Credit Facility, and the remaining amount of $10.0 million will be available for drawdown through December 2012. The Credit Facility carries an interest rate equal to the greater of the prime rate plus 2.75% or 6% for the first tranche, and a rate equal to the greater of the prime rate plus 5.5% or 8.75% for the second and third tranches. The loan facility was subject to interest-only payments through September 2012, which was repayable in 30 equal monthly installments of principal and interest after the interest-only period, and had a maturity date of March 2015. However, during the six months ended June 30, 2012, the Company achieved certain financial milestones under the Credit Facility which provided for the extension of: a) the drawdown period from August 2012 to December 2012, b) the beginning of the interest-only period from September 2012 to March 2013, and c) the maturity date from March 2015 to September 2015.

As of December 31, 2011, the future principal payments on the debt are as follows (in thousands):

In conjunction with the Credit Facility, the Company issued warrants to purchase up to 120,961 shares of Company stock as follows: (1) shares of Series D convertible preferred stock with an exercise price equal to $8.4738 per share or (2) shares of the next round of preferred stock financing at the per share price for such shares upon drawdown of the entire loan amount. Of this amount, warrants to purchase 56,054 shares of Series D convertible preferred stock became exercisable upon the drawdown of the first and second tranches and have an exercise price of $8.4738 per share. At the time of issuance, the aggregate fair value of these warrants was $281,000. The Company also paid a net facility charge of $165,000 upon drawdown of the first tranche of the loan. The fair value of warrants and net facility charge were recorded as debt discount to be amortized as interest expense over the contractual term of the loan agreement using the effective interest rate method. As a result of the debt discount, the effective interest rate for the Credit Facility differs from the contractual rate. During the year ended December 31, 2011 and six months ended June 30, 2012, the Company recognized interest expense related to amortization of the debt discount in the amount of $38,000 and $92,000.

Under the Credit Facility, the Company granted the financial institution a security interest in all of the Company’s assets. If the Company has available cash and marketable securities on hand of at least $20.0 million, the financial institution may release the security interest on the Company’s intellectual property. However, if at any time after release of the intellectual property, the available cash and marketable securities on hand is less than $10.0 million, the Company will grant the financial institution a security interest on its intellectual property.

The Company was in compliance with all covenants under its loan facility agreement as of December 31, 2011 and June 30, 2012. The Credit Facility provides certain reporting covenants, among others, relating to delivery of audited financial statements to the financial institution. In May 2012, the Company failed to comply with the covenant that required delivery of audited financial statements for the year ended December 31, 2011 within the time period set forth in the Credit Facility. The lender granted a waiver arising from the Company’s failure to comply with this reporting covenant.

The Company leases its corporate office under noncancelable operating leases. In February 2007, the Company executed a lease agreement for its corporate office in San Francisco for initial monthly rent of $19,000, which expired in December 2010. In October 2010, the Company moved its corporate office within San Francisco and entered into a four-year lease which will expire in October 2014. The Company’s initial monthly rent for the San Francisco lease is $62,000. In addition to its corporate office, the Company entered into a lease in New York for a sales office at monthly rent of $10,000, which expired in June 2011. In February and April 2011, the Company entered into two operating leases in Denver and New York to expand its sales offices. These leases expire at various times through April 2014. Monthly rent under Denver and New York leases are $27,000

and $11,000. Rental expense from the facility leases are recognized on a straight-line basis over the lease term. Rent expense was $432,000, $611,000, $1.1 million, $531,000 and $599,000 during the years ended December 31, 2009, 2010, and 2011 and six months ended June 30, 2011 and 2012.

As of December 31, 2011, the Company’s minimum payments under the noncancelable operating leases are as follows (in thousands):

In March 2012, the Company entered into a sublease agreement for additional office space which will expire in March 2013. The monthly rent for the new office space is $29,000.

During the years ended December 31, 2009, 2010, and 2011 and six months ended June 30, 2012, the Company has entered into various capital lease agreements for certain hardware and equipment for use by the Company and its employees. The lease terms have ranged from 24 to 36 months.

The following is a schedule of future minimum lease payments due under the capital lease obligation as of December 31, 2011 (in thousands):

The Company is subject to legal proceedings, claims and litigation arising in the ordinary course of business. In July 2011, a non-practicing entity brought suit against Trulia for patent infringement. In September 2011, the Company entered into a license agreement to purchase a license for these patents for $550,000 and, as a result, the claim against the Company was dropped.

The agreement also provides for an additional contingent payment of $350,000 if the Company files its initial Registration Statement with the SEC prior to January 11, 2015 and its shares become publicly listed on either the NASDAQ or NYSE exchanges following the completion of the Company’s IPO. The Company did not accrue any amounts related to the contingent payment as it concluded that the payment of this amount is not probable as of December 31, 2011 and June 30, 2012. The Company will, however, accrue for losses for any known contingent liabilities when future payment is probable and the amount is reasonably estimable.

As of December 31, 2010, 2011 and June 30, 2012, the Company had reserved shares of common stock, on an as-if converted basis, for issuance as follows:

As of December 31, 2010, 2011 and June 30, 2012, the Company has outstanding Series A, B, C and D convertible preferred stock (individually referred to as “Series A, B, C or D” or collectively “Preferred Stock”) as follows (in thousands, except for share data):

The holders of the Company’s Preferred Stock have the following rights, preferences, and privileges:

Each share of Preferred Stock is convertible, at the option of the holder thereof, at any time after the date of issuance of such share, into such number of fully paid and non-assessable shares of common stock as determined by dividing the original issue price for such Series by the then effective conversion price for that Series (the

“Conversion Rate”). The Conversion Rate is subject to adjustment for any stock dividends, combinations or splits with respect to such shares. Additionally, each share of Preferred Stock is automatically convertible into shares of common stock at the then effective Conversion Rate for such Series (i) with the approval, by affirmative vote, written consent, or agreement, of the holders of not less than two-thirds of the outstanding Preferred Stock voting together as a single class; (ii) upon the voluntary conversion by the holders of not less than two-thirds of the Preferred Stock issued by the Company; or (iii) immediately prior to the completion of an underwritten initial public offering with proceeds to the Company of not less than $50.0 million. The Conversion Rate for each series of preferred stock is 1-for-1 as of December 31, 2010, 2011 and June 30, 2012.

The holders of Series A, B, C and D are entitled to receive non-cumulative dividends on a pari passu basis, and in preference to common stockholders, at the rate of $0.04836, $0.08319, $0.239262 and $0.67788 per share (as adjusted for any stock dividends, combinations or splits with respect to such shares) per annum payable out of funds legally available. Such dividends are payable when, and if declared by the Board of Directors, acting in its sole discretion. After payment of dividends at the rates set forth above, any additional dividends declared will be distributed among all holders of Preferred Stock and common stock in proportion to the number of shares of common stock that would then be held by each such holder if all shares of Preferred Stock were converted into common stock. No dividends have been declared through June 30, 2012.

In the event of any liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, the holders of the Preferred Stock are entitled to receive, prior and in preference to any distribution of the assets of the Company to the holders of common stock, an amount equal to (i) 100% of the original issue price for each share of Series A, 100% of the original issue price for each share of Series B, 107.5% of the original issue price for each share of Series C, and 100% of the original issue price for each share of Series D, plus (ii) all declared but unpaid dividends on such shares. If the assets and funds available for distribution to the holders of the Preferred Stock are insufficient to pay the stated preferential amounts in full, the entire assets and funds of the Company legally available for distribution will be distributed with equal priority and pro rata among the holders of the Preferred Stock in proportion to the preferential amount each such holder would otherwise be entitled to receive. The remaining assets, if any, are to be distributed ratably to the holders of the common stock and Preferred Stock, on an as-if-converted basis, provided that the holders of Series A, Series B, Series C and Series D are not entitled to any proceeds above $0.6045, $1.0398, $2.9907 and $8.47368 per share. Thereafter, if assets remain, they will be distributed to the holders of common stock on a pro rata basis.

The Company classified the Preferred Stock within shareholders’ equity since the shares are not redeemable, and the holders of the Preferred Stock cannot effect a deemed liquidation of the Company outside of the Company’s control.

The holders of the Preferred Stock are entitled to the number of votes equal to the number of shares of common stock into which these shares could then be converted.

In September 2011, the Company entered into a $20.0 million Credit Facility discussed further in Note 6. In connection with the Credit Facility, the Company issued a warrant to purchase up to 120,961 shares of Series D with an exercise price of $8.4738 per share, however, only 56,054 shares are exercisable as of December 31, 2011 and June 30, 2012. The exercisability of the warrant is triggered upon specified drawdowns on the Credit Facility. As of December 31, 2011 and June 30, 2012, the Company had only drawdown $10.0 million from the total $20.0 million underlying the Credit Facility. If the Company draws the remaining $10.0 million, these other shares will become exercisable under the warrant. The warrant contains certain anti-dilution provisions which require the Company to lower the exercise price of and adjust the number of shares underlying the warrants upon any future down-round financings. Therefore, the exercise price and the shares underlying the warrant are potentially subject to change. The warrant expires at the earlier of (1) 10 years from issuance, (2) five years from the effectiveness of an initial public offering, or (3) completion of a liquidation event in which the underlying preferred shares are redeemed for twice the exercise price of the warrant. At the time of issuance, the aggregate fair value of the warrant in the amount of $281,000 was determined using a Monte Carlo model incorporating two scenarios, one with a future equity financing and one without. The model also used the following assumptions: expected term of 1.2 years, risk-free interest rate of 0.2%, expected volatility of 55.0% and expected dividend yield of 0%. The fair value of the warrant was recorded as a warrant liability upon issuance.

During the year ended December 31, 2011 and six months ended June 30, 2012, the Company recognized a charge to earnings of $16,000 and $323,000 from remeasurement of the fair value of the warrant, which was recorded through the statements of operations.

The Company determined the fair value of the outstanding convertible preferred stock warrant of $297,000 and $620,000 as of December 31, 2011 and June 30, 2012 with the following assumptions:

Term—The term represents a weighted average of the remaining term under probable scenarios used to determine the fair value of the underlying stock. A weighted average term was determined to be more appropriate than the contractual term due to potential adjustments to the related expiration date for the warrant under multiple scenarios;

Risk-free interest rate—The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of grant for zero coupon U.S. Treasury notes with maturities approximately equal the term of the warrant;

Expected volatility—The expected volatility is derived from historical volatilities of several unrelated publicly listed peer companies over a period approximately equal to the term of the warrant because the Company has limited information on the volatility of the preferred stock since there is currently no trading history. When making the selections of industry peer companies to be used in the volatility calculation, the Company considered the size, operational and economic similarities to the Company’s principle business operations; and

Expected dividend yield—The expected dividend yield is assumed to be zero as the Company has never paid dividends and has no current plans to do so.

In July 2010, in conjunction with services provided by a third party consultant, the Company issued a warrant to purchase 12,735 shares of common stock with an exercise price of $3.54 per share and expiration date of July 19, 2015. The warrant is exercisable with cash or through a cashless exercise provision. Under the cashless exercise provision, the holder may, in lieu of payment of the exercise price in cash, surrender the warrant and receive a net amount of shares based on the fair market value of the Company’s common stock at the time of exercise of the warrant after deducting the aggregate exercise price. The fair value of the warrant in the amount of $16,000 was recorded as additional paid-in capital upon issuance and was not subject to remeasurement at each reporting period. The fair value of the warrant was calculated using the Black-Scholes option-pricing model with the following assumptions: contractual term of 5 years, risk-free interest rate of 1.7%, expected volatility of 55.0% and expected dividend yield of 0%. In March 2011, the warrant was exercised with cash proceeds of $45,000.

In September 2011, in conjunction with services provided by a third party consultant, the Company issued a warrant to purchase 44,646 shares of common stock with an exercise price of $4.29 per share and expiration date of February 14, 2016. The outstanding warrant will expire at the earlier of an initial public offering, change of control or expiration date. The warrant is exercisable with cash or through a cashless exercise provision. The fair value of the warrant in the amount of $93,000 was recorded as additional paid-in capital upon issuance and was not subject to remeasurement at each reporting period. The fair value of the warrant was calculated using the Black-Scholes option-pricing model with the following assumptions: contractual term of 4.5 years, risk-free interest rate of 0.7%, expected volatility of 55.0% and expected dividend yield of 0%.

The Company has granted options under its 2005 Stock Incentive Plan (the “2005 Plan”). Under the terms of the 2005 Plan, the Company has the ability to grant incentive (“ISO”) and nonstatutory (“NSO”) stock options, restricted stock awards and restricted stock units. As of December 31, 2010, 2011 and June 30, 2012, 2,407,555, 4,474,605 and 5,141,271 shares of common stock were reserved under the 2005 Plan for the issuance of ISOs, NSOs, or restricted stock to eligible participants. Under the 2005 Plan, the ISOs may be granted at a price per share not less than the fair market value at the grant date. The NSOs may be granted at a price per share not less than 85% of the fair market value at the date of grant. Options generally vest at 25% after the first year and then at 1/36 of the remaining shares each month thereafter and expire 10 years from the grant date. Certain options vest monthly over two to four years.

Stock option activity under the 2005 Plan during the years ended December 31, 2009, 2010, 2011 and six months ended June 30, 2012, is as follows:

The options exercisable as of December 31, 2011 and June 30, 2012 included options that were exercisable prior to vesting. The weighted average grant date fair value of options granted during the years ended December 31, 2009, 2010, and 2011 and the six months ended June 30, 2012 was $1.38, $1.59, $2.28 and $4.80.

Aggregate intrinsic value represents the difference between the estimated fair value of the underlying common stock and the exercise price of outstanding, in-the-money options. The aggregate intrinsic value of options exercised was $322,000, $760,000, $902,000 and $1.4 million during the years ended December 31, 2009, 2010, and 2011 and six months ended June 30, 2012. The total estimated grant date fair value of employee options vested during the years ended December 31, 2009, 2010, and 2011 and six months ended June 30, 2012 was $484,000, $336,000, $1.2 million and $909,000.

As of December 31, 2011 and June 30, 2012, total unrecognized compensation cost related to stock-based awards granted to employees was $3.2 million, net of estimated forfeitures of $758,000, and $3.9 million, net of estimated forfeitures of $891,000. These costs will be amortized on a straight-line basis over a weighted average vesting period of 3.03 and 2.85 years.

Additional information regarding the Company’s stock options outstanding and vested and exercisable as of December 31, 2011 is summarized below:

Additional information regarding the Company’s stock options outstanding and vested and exercisable as of June 30, 2012 is summarized below:

The fair value of each grant of stock options was determined by the Company and its Board of Directors using the methods and assumptions discussed below. Each of these inputs is subjective and generally requires significant judgment to determine.

Valuation Method—The Company estimates the fair value of its stock options using the Black-Scholes option-pricing model.

Expected Term—The expected term represents the period that the stock-based awards are expected to be outstanding. The Company estimates the expected term for its option grants based on a study of publicly traded industry peer companies and the historical data on employee exercises and post-vesting employment termination behavior taking into account the contractual life of the award.

Expected Volatility—The expected volatility is derived from the historical stock volatilities of several comparable publicly listed peers over a period approximately equal to the expected term of the options because the Company has limited information on the volatility of its common stock since the Company has no trading history. When making the selections of the comparable industry peers to be used in the volatility calculation, the Company considered the size, operational and economic similarities to its principle business operations.

Fair Value of Common Stock—The fair value of the common stock underlying the stock options has historically been determined by the Company’s board of directors. Because there has been no public market for the Company’s common stock, the board of directors has determined the fair value of the common stock at the time of the option grant by considering a number of objective and subjective factors including contemporaneous valuations performed by unrelated third-party specialists, valuations of comparable companies, operating and financial performance, lack of liquidity of capital stock and general and industry-specific economic outlook, amongst other factors. The fair value of the underlying common stock shall be determined by the board of directors until such time that the Company’s common stock is listed on an established stock exchange or national market system.

Risk-Free Interest Rate—The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for zero coupon U.S. Treasury notes with maturities approximately equal to the expected term of the options.

Expected Dividend—The expected dividend has been zero as the Company has never paid dividends and has no expectations to do so.

Forfeiture Rate—The Company estimates its forfeiture rate based on an analysis of its actual forfeitures and will continue to evaluate the adequacy of the forfeiture rate based on actual forfeiture experience, analysis of employee turnover behavior, and other factors. The impact from a forfeiture rate adjustment will be recognized in full in the period of adjustment, and if the actual number of future forfeitures differs from that estimated, the Company may be required to record adjustments to stock-based compensation expense in future periods.

The fair value of each employee stock option was estimated at the date of grant using a Black-Scholes option-pricing model with the following weighted average assumptions:

The Company recorded compensation expense for options granted to employees and nonemployees as follows (in thousands):

The Company capitalized stock-based compensation of $1,000, $17,000, $22,000, $16,000 and $18,000 as product development costs during the years ended December 31, 2009, 2010, 2011 and six months ended June 30, 2011 and 2012.

During the years ended December 31, 2009, 2010, and 2011, the Company granted nil, nil and 16,216 stock options to nonemployees. Through June 30, 2012, no stock-based compensation expense was recognized related to the options granted during the year ended December 31, 2011 as these nonemployee options have performance conditions that the Company determined are not probable as of June 30, 2012. Such options are subject to remeasurement using the Black-Scholes option-pricing model as the options vest.

There were no grants made to nonemployees during the six months ended June 30, 2011 and 2012.

The following table sets for the computation of the Company’s basic and diluted net loss per share attributable to common stockholders during the years ended December 31, 2009, 2010, and 2011 and six months ended June 30, 2011 and 2012 (in thousands, except share and per share data):

The following outstanding shares of common stock equivalents were excluded from the computation of the diluted net loss per share attributable to common stockholders for the periods presented because including them would have been antidilutive:

The following table sets forth the computation of the Company’s unaudited pro forma basic and diluted net loss per share attributable to common stockholders during the year ended December 31, 2011 and six months ended June 30, 2012 (in thousands, except share and per share data):

The Company accounts for income taxes in accordance with authoritative guidance, which requires the use of the asset and liability method. Under this method, deferred income tax assets and liabilities are determined based upon the difference between the financial statement carrying amounts and the tax basis of assets and liabilities and are measured using the enacted tax rate expected to apply to taxable income in the years in which the differences are expected to be reversed. For the years ended December 31, 2009, 2010, and 2011 and six months ended June 30, 2011 and 2012, the Company did not have taxable income and, therefore, no tax liability or expense has been recorded in the financial statements.

The following table presents a reconciliation of statutory federal rate and the Company’s effective tax rate for the periods presented:

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets and liabilities as of December 31, 2010 and 2011 were as follows (in thousands):

The Company provided a full valuation allowance for net operating losses, credits and other deferred tax assets for the state of California and the United States. A valuation allowance is provided when based upon the available evidence, management concludes that it is more likely than not that some portion of the deferred tax assets will not be realized. The Company maintained a full valuation allowance as of December 31, 2010 and 2011 due to the uncertainty of realizing future tax benefits from its net operating loss carryforwards and other deferred tax assets. There were increases in the valuation allowance during the years ended December 31, 2009, 2010, and 2011 of $2.6 million, $2.1 million and $2.2 million. The increase in the valuation allowance for the year ended December 31, 2010 includes the valuation allowance for the acquired net operating loss from Movity.

As of December 31, 2011, the Company had federal and state net operating loss carry forwards of $29.7 million and $24.9 million. The federal net operating loss carry forward will expire at various dates beginning in 2025, if not utilized. The state net operating loss carry forward will expire at various dates beginning in 2015, if not utilized.

Utilization of the net operating loss carryforwards and credits may be subject to a substantial annual limitation due to the ownership change limitations provided by Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the expiration of net operating losses and credits before utilization.

As of December 31, 2010 and 2011, the Company had federal technology and development credit carry forward of $15,000. The general business credit will expire beginning in 2025, if not utilized.

The Company adopted authoritative guidance under ASC 740 on January 1, 2007, which clarifies the accounting for uncertainty in tax positions recognized in the financial statements. The Company has not been audited by the Internal Revenue Service or any state tax authority. The Company is subject to taxation in the U.S.

and various states. Due to the Company’s net losses, substantially all of its federal and state income tax returns since inception are still subject to audit.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):

If the $475,000 of unrecognized income tax benefits is recognized, there would be no impact to the effective tax rate as any change will fully offset the valuation allowance.

The Company does not have any additional tax positions that are expected to significantly increase or decrease within twelve months of the year ended December 31, 2011.

The Company has a defined contribution 401(k) retirement plan covering all employees who have met certain eligibility requirements. Eligible employees may contribute pretax compensation up to the maximum amount allowable under Internal Revenue Service limitations. Employee contributions and earnings thereon vest immediately. The Company matches up to 3% of the employee’s contributions. The Company’s expense related to its benefit plan during the years ended December 31, 2009, 2010, and 2011 and six months ended June 30, 2011 and 2012 was $143,000, $192,000, $388,000, $164,000 and $321,000.

The Company evaluated subsequent events through May 30, 2012 and September 6, 2012 as to Note 14, the date on which the December 31, 2011 financial statements were issued and retrospectively revised, respectively. For the six months ended June 30, 2012, the Company evaluated subsequent events through August 16, 2012 and September 6, 2012 as to Note 14, the date on which these interim financial statements were issued and retrospectively revised, respectively.

In September 2012, the Company’s board of directors and stockholders approved an amendment to the amended and restated certificate of incorporation. The amendment provided for a 1-for-3 reverse stock split of the outstanding common stock and outstanding convertible preferred stock (collectively, “Capital Stock”), which became effective on September 6, 2012. Accordingly, (i) every three shares of Capital Stock have been combined into one share of Capital Stock, (ii) the number of shares of Capital Stock into which each outstanding option or warrant to purchase Capital Stock is exercisable, as the case may be, have been proportionately decreased on a 1-for-3 basis, and (iii) the exercise price for each such outstanding option or warrant to purchase Capital Stock has been proportionately increased on a 1-for-3 basis. All of the share numbers, share prices, and exercise prices have been adjusted within these financial statements, on a retroactive basis, to reflect this 1-for-3 reverse stock split. The amendment to the certificate of incorporation also changed the automatic conversion feature of the convertible preferred stock from converting upon the effectiveness of the registration statement of which this prospectus forms a part to converting immediately prior to the closing of this offering. Upon completion of this offering, the Company’s authorized shares will consist of 1,000,000,000 shares of common stock and 20,000,000 shares of preferred stock.

In August 2012, the Company amended its Denver lease agreement to add office space in Denver. The monthly lease expense for the Denver leases will increase by $16,000 until February 2013 and by another $16,000 through April 2014.

In September 2012, the Company’s board of directors adopted and stockholders approved the 2012 Equity Incentive Plan which will be effective immediately before the effective date of the Company’s initial public offering. Under the plan, a total of 2,370,000 shares of common stock have been reserved for issuance plus up to 1,000,000 shares from the expiration or termination of awards under the 2005 Plan. The shares available will be increased at the beginning of each fiscal year by the lesser of (i) 2,100,000 shares, (ii) 4% of outstanding common stock as of the beginning of the year, or (iii) such other amounts as determined by the Company’s board of directors.

The following table sets forth all expenses to be paid by us, other than underwriting discounts and commissions, in connection with this offering. All amounts shown are estimates except for the SEC registration fee, the FINRA filing fee, and the listing fee.

Section 145 of the Delaware General Corporation Law authorizes a corporation’s board of directors to grant, and authorizes a court to award, indemnity to officers, directors, and other corporate agents.

The underwriting agreement filed as Exhibit 1.1 to this registration statement provides for indemnification by the underwriters of the Registrant and its officers and directors for certain liabilities arising under the Securities Act and otherwise.

Share and per share amounts contained in this Item 15 reflect the 1-for-3 reverse stock split of our capital stock, which became effective September 6, 2012.

We believe these transactions were exempt from registration under the Securities Act in reliance upon Section 4(2) of the Securities Act or Regulation D promulgated thereunder, or Rule 701 promulgated under Section 3(b) of the Securities Act as transactions by an issuer not involving any public offering or pursuant to benefit plans and contracts relating to compensation as provided under Rule 701. The recipients of the securities in each of these transactions represented their intentions to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof, and appropriate legends were placed upon the stock certificates issued in these transactions. All recipients had adequate access, through their relationships with us, to information about Trulia.

(a) Exhibits. The following exhibits are filed herewith or incorporated herein by reference:

All other schedules have been omitted because they are not required, not applicable, or the required information is otherwise included.

The undersigned Registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreement certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, or the Act, may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

Pursuant to the requirements of the Securities Act of 1933, as amended, the registrant has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of San Francisco, State of California, on September 6, 2012.

Pursuant to the requirements of the Securities Act of 1933, as amended, this registration statement on Form S-1 has been signed by the following persons in the capacities and on the dates indicated.
