PART 1

ITEM I. BUSINESS

Overview

We provide a cloud-based marketing and sales software platform that enables businesses to deliver an inbound experience. An inbound marketing and sales experience attracts, engages and delights customers by being more relevant, more helpful, more personalized and less interruptive than traditional marketing and sales tactics. Our software platform features integrated applications to help businesses attract visitors to their websites, convert visitors into leads, close leads into customers and delight customers so that they become promoters of those businesses. These integrated applications include social media, search engine optimization, blogging, website content management, marketing automation, email, CRM, analytics and reporting.

People have transformed how they consume information, research products and services, make purchasing decisions and share their views and experiences. Today, customers are blocking out the tactics from the traditional marketing and sales playbook, such as cold calls, unsolicited emails and disruptive advertisements. Customers are taking more control of the purchasing process by using technology, including search engines and social media, to research products and services. Despite this transformation, most businesses are using an outdated marketing and sales playbook that is essentially the same today as it was 10 years ago. To compete effectively, we believe businesses need to deliver an inbound experience by adopting new strategies and technologies to attract, engage and delight customers.

We designed our all-in-one platform from the ground up to enable businesses to provide an inbound experience to their prospects and customers. At the core of our platform is a single inbound database for each business that captures its customer activity throughout the customer lifecycle. Our platform uses our centralized inbound database to empower businesses to create more personalized interactions with customers, such as personalized emails, personalized social media alerts, personalized websites and targeted alerts for sales people. We provide a comprehensive set of integrated applications on our platform, which offers businesses ease of use, power and simplicity. We designed and built our platform to serve a large numbers of customers of any size with demanding use cases.

While our platform can scale to the enterprise, we focus on selling to mid-market businesses, which we define as businesses that have between 10 and 2,000 employees, because we believe we have significant competitive advantages attracting and serving them. We efficiently reach these businesses at scale through our proven inbound go-to-market approach and more than 2,200 marketing agency partners worldwide. Our platform is particularly suited to serving the needs of mid-market B2B companies. These mid-market businesses seek an integrated, easy to implement and easy to use solution to reach customers and compete with organizations that have larger marketing and sales budgets. As of December 31, 2014, we had 13,607 customers of varying sizes in more than 90 countries, representing almost every industry.

We have a leading brand in the cloud-based inbound marketing and sales software industry. Our brand recognition comes from our thought leadership, including our blog, which attracts more than 1.5 million visits each month, and our commitment to innovation. Our founders, Brian Halligan and Dharmesh Shah, wrote the best-selling marketing book Inbound Marketing: Get Found Using Google, Social Media and Blogs. We also have one of the largest social media followings in our industry and our INBOUND conference is one of the largest inbound industry events, with over 10,000 registered attendees in 2014.

We sell our platform on a subscription basis. Our total revenue increased from $51.6 million in 2012, to $77.6 million in 2013, and to $115.9 million in 2014, representing year-over-year increases of 50% in 2013 and 49% in 2014. We had net losses of $18.8 million in 2012, $34.3 million in 2013, and $48.2 million in 2014.

Industry Background

People Have Changed How They Interact with Businesses

We believe an effective way to illustrate how people have transformed the way they consume information, research products and services, make purchasing decisions and share their views and experiences is by describing two hypothetical people—Traditional Ted and Modern Meghan.

Traditional Ted is an executive at a 300 person company in 2004. He keeps up to date on his industry by attending trade shows and reading the monthly industry print publication, often scanning the ads to see the vendors’ new products. He gets a fair amount of unsolicited emails from salespeople and marketers and sees an increasing number of ads on websites he visits. He also takes sales calls from vendors to stay current on industry developments. Ted opens his mail daily, and when his phone rings, he answers it because it is a critical communication tool. When Ted is looking for a new vendor, he will try to recall the ads he has seen recently or go through the brochures he has been mailed which he keeps in a file in his desk. If Ted is frustrated with a vendor, he calls the vendor and tells a couple of his colleagues about his bad experience. To relax, Ted watches TV and reads the newspaper, both of which contain advertisements.

Modern Meghan is an executive at a 300 person company in 2014. She keeps up to date on her industry by reading a number of industry blogs, following key companies and influencers on Twitter and LinkedIn and listening to podcasts in her car during her commute. She has an ad blocker running in her web browser and an email filter to block out unwanted messages. She rarely checks her mail because it is mostly “junk.” Meghan does not have a landline phone because “only salespeople call me there,” and she never answers her smartphone unless she recognizes the number. Meghan spends much more time on her phone using apps and the web than she does talking on it. If she is looking for a vendor for something her company needs, she starts by searching on Google and then asking her peers in her LinkedIn network about their experiences with different vendors. She does not even bother to talk to any of the vendor’s salespeople until she has narrowed the list and has already completed most of her decision-making process. When Meghan has trouble with one of her vendors, she contacts the vendor, but if she is not satisfied with the response, she sometimes writes a negative review online and posts a link to it on Twitter. In her free time, Meghan relaxes by watching TV shows she has previously recorded on her DVR so she can fast forward through the commercials.

We believe all of us are becoming more like Modern Meghan and less like Traditional Ted. Yet, most businesses are still doing marketing, sales and service as if everyone is like Ted. To be effective today, businesses need to transform to attract, engage and delight customers like Meghan.

The Traditional Business Playbook is Broken

Traditionally, most businesses have followed the same marketing and sales playbook to generate leads, close sales and provide support to their customers. Today, however, customers are increasingly selecting their own communication channels and expecting personalized experiences. They are blocking out traditional marketing and sales tactics, such as cold calls, unsolicited emails and disruptive advertisements, and instead, they are using search engines and social media to research products and services before they contact a vendor. Customers are increasingly taking more control of the purchasing process and influencing the purchasing behavior of others.

Customers are blocking out traditional marketing and sales tactics. Customers are ignoring traditional marketing and sales tactics, often by using technology to block them out. For example:

• There are over 223 million phone numbers that have been placed on the U.S. Do Not Call registry.

• 91% of people have unsubscribed from email marketing lists.

• Email services and spam filters are increasingly enabling customers to filter out and de-prioritize promotional messages.

4

• 68% of people who record TV content do so to skip advertisements, according to a recent Motorola Mobility study based on data collected in December 2012.

• Online advertising has limited engagement. According to DoubleClick, as of March 26, 2014, overall 3-month average industry click-through rates on display ads is only 0.2%.

Customers are taking control of the purchasing process. Customers can now get the information they need on their own terms. Using search engines, social media and websites, customers can research vendors and actively seek recommendations from members of their social networks. As a result, customers no longer need to talk to a salesperson until they have completed most of their purchasing decision. This limits the amount of influence businesses can have on purchase decisions when using the traditional business playbook. A 2012 Corporate Executive Board (CEB) study of more than 1,400 business-to-business customers across industries revealed that 57% of a typical purchase decision is already made before a customer even talks to a supplier.

Customers are influencing the purchasing behaviors of others. Customers are relying less on the promotional material from businesses and instead using online reviews and input from other purchasers to make their purchasing decision. Such social behavior is self-reinforcing: social buyers themselves are social sellers who influence others’ purchasing decisions. According to a survey conducted by Dimensional Research in 2013, 88% of respondents said that online reviews influenced their buying decisions. In addition, the Social Media Report published by Nielsen and NM Incite in 2011 revealed that 60% of consumers researching products through multiple online sources learned about a specific brand or retailer through social networking sites.

Businesses Need a New Playbook—The Inbound Experience

Businesses need a more effective way to attract, engage and delight customers who have access to an abundance of information and an ability to block traditional marketing and sales tactics. To do this, businesses need to deliver an inbound experience, which enables them to be more helpful, more relevant and less interruptive to their customers.

To deliver an inbound experience, businesses need to transform how they market, sell and serve customers.

• Marketing: Businesses need to attract potential customers by maximizing search engine rankings, having an engaging social media presence, and creating and distributing useful and relevant content. Businesses need to personalize their customer interactions on websites, in social media and in emails to engage customers.

• Sales: Businesses need to build relationships with potential customers and become their trusted advisors. They must learn about and react to the signals being sent by customers through websites, social media and emails, to provide personalized and helpful responses.

• Service: Businesses need to delight their customers and inspire them to become vocal promoters by exceeding their expectations. Every customer has a stronger, more public voice today through blogs and social media, underscoring the importance of positive reviews and referrals in building a quality brand.

Existing Applications are Not Adequate for an Integrated Inbound Experience

Today, businesses often use a variety of point applications for their marketing and sales efforts, including advertising, marketing automation, content management, blogging, social media management, analytics, sales management and CRM. Most of these point applications were not designed to deliver an inbound experience. Typically, they do not provide a central view of all customer interactions across channels, are difficult and expensive to implement and use together, and make it hard to measure results. We believe that these existing point applications were not designed with the platform, architecture and functionality necessary to deliver a seamless integrated inbound experience.

5

Not Designed for an Inbound Experience. Traditional marketing applications through rely on advertising and cold calling for lead generation instead of inbound methods. These applications are not designed to personalize and optimize every interaction with customers on websites, in social media and by email across devices, and do not typically allow sales and service teams to see the signals their prospects are sending in real time.

No Centralized Inbound Database of Customer Interactions. Businesses typically need to use one point application for website content management, a different point application for blogging, another point application for social media management, another point application for email and marketing automation, another point application for content personalization, another point application for analytics, another point application for sales management and CRM, and yet another point application to alert salespeople of key customer signals in real time. This disparate collection of point applications makes it difficult to get a 360-degree view of a customer’s interactions and use that data to provide a better customer experience and drive a more effective marketing and sales process. In addition, existing point applications are typically not designed to manage, process and analyze all of the customer data created by these various touchpoints because they use older technologies, not big data technologies such as HBase, Hadoop that are designed for massive scale.

Difficult and Expensive to Implement and Use. Using a collection of disparate point applications means a separate implementation process for each. Often businesses will need to use outside consultants or hire new employees with specific technical expertise to implement and use these different applications, resulting in significant additional costs. This collection of disparate point applications also requires that businesses manage a variety of different log-ins and user interfaces, as well as get support from different vendors, often just to do something the business sees as one process, such as running a marketing campaign. While ease of implementation and use are important for businesses of all sizes, they are critical for mid-market businesses.

Hard to Measure Results. Because all the customer touchpoints through the marketing, sales and service processes are typically stored in different disconnected point applications, it is very difficult to get a 360-degree view of a customer’s interactions and measure the effectiveness of marketing and sales programs. Businesses will often purchase yet another application to try to measure results across their multiple applications, adding even more expense and complexity to an already complex collection of different point applications.

Market Opportunity

We believe there is a large market opportunity created by the fundamental transformation in marketing and sales. Businesses of nearly all sizes and in nearly all industries can benefit from delivering an inbound experience to attract, engage and delight their customers. We focus on selling our platform to mid-market businesses. As of December 31, 2014, we had 13,607 customers, and our average subscription revenue per customer for the year ended December 31, 2014 was $8,926. According to AMI Partners, in 2014, there were 1.6 million of these mid-market businesses with a website presence in the United States and Canada and 1.4 million in Europe. According to a January 2014 study by Mintigo of 186,500 U.S.-based B2B companies of varying sizes, only 3% of those companies had implemented any of the most common marketing automation applications.

We believe our platform addresses several segments of existing marketing, sales and services software and that spending in each of these segments will increasingly shift to platforms that enable an inbound experience. According to a May 2014 report by IDC, worldwide spending on CRM applications, including marketing automation, sales automation, customer service and contact center, was forecast to be $24.4 billion in 2014 and is expected to grow to $31.7 billion in 2018.

Advantages of Our Solution

We provide a cloud-based, all-in-one inbound marketing and sales software platform that helps businesses attract, engage and delight customers throughout the customer lifecycle. Our platform features a central

6

inbound database of customer interactions and integrated applications to help businesses attract visitors to their websites, convert visitors into leads, close leads into customers and delight customers so they become promoters of those businesses.

Designed for an Inbound Experience. Our platform was architected from the ground up to enable businesses to transform their marketing and sales playbook to meet the demands of today’s customers. Our platform includes integrated applications to help businesses efficiently attract more customers through search engine optimization, social media, blogging and other useful content. In addition, our platform is designed to help businesses personalize and optimize interactions with their customers through websites, landing pages, social media and emails, and across devices.

Ease of Use of All-In-One Platform. We provide a set of integrated applications on a common platform, which offers businesses ease of use and simplicity. Our platform has one login, one user interface, one inbound database and one number to call for support: 888-HUBSPOT. Our platform is designed to be used by people without technical training, does not require an expert or technical system administrator and was built to make it easy to get started. Because of its ease of use and integration, our platform enables businesses to focus on attracting, engaging and delighting customers, instead of spending time and money coordinating their marketing and sales efforts across multiple point applications.

Power of All-In-One Platform. At the core of our platform is a single inbound database for each business that captures its customer activity throughout the customer lifecycle. For example, our platform creates a unified timeline incorporating all the interactions with a particular person. If a business’s customer visits its website, comments on its blog, opens an email it sent, interacts with the business on Twitter, watches one of its videos, fills out a form, or is marked as a sales opportunity by its salesperson, all of that activity is centrally managed and presented on the timeline for that contact and is available for use across our applications. Our platform also makes it easy to use the customer data to empower more personalized interactions with the customer, such as personalized social media alerts, personalized content on a business’s website, personalized emails and targeted alerts to its sales people.

Clear ROI for Customers. Our platform delivers proven and measurable results for our customers. Our customers often experience significant increases in the volume of traffic to their websites, the volume of inbound leads and the rate of converting leads into customers. Based on our analysis of customer use in 2012 and 2013, our customers experienced, on average, a 5.7x increase in the number of leads that they generated after 12 months of active use of our platform.

Scalability. Our platform was designed and built to serve a large number of customers of any size and with demanding use cases. Our platform currently processes billions of data points each week, and we use leading global cloud infrastructure providers and our own automation technology to dynamically allocate capacity to handle processing workloads of all sizes. We have built our platform on modern technologies, including HBase and Hadoop, which we believe are more scalable than traditional database technologies. Our scalability gives us flexibility for future growth and enables us to service a large variety of businesses of different sizes across different industries.

Extendable and Open Architecture. Our platform features a variety of open APIs that allows easy integration of our platform with other applications. We enable our customers to connect our platform to their other applications, including CRM and ecommerce applications. By connecting third-party applications, our customers can leverage our centralized inbound database to perform additional functions and analysis.

Our Competitive Strengths

We believe that our market leadership position is based on the following key strengths:

Leading Platform. We have designed and built a world-class, inbound marketing and sales software platform. We believe our customers choose our platform over others because of its powerful, integrated and

7

easy to use applications. Independent customer reviews and ratings of our platform compared to other applications show that we have high customer satisfaction. As of December 31, 2014 on G2Crowd (an independent business software and services review website), the features and functions of our platform were ranked #1 in customer satisfaction in the following categories: marketing automation, social media management, email marketing, and search marketing.

Market Leadership and Strong Brand. We are a recognized thought leader in the cloud-based inbound marketing and sales software industry with a leading brand. Our founders, Brian Halligan and Dharmesh Shah, wrote the best-selling marketing book Inbound Marketing: Get Found Using Google, Social Media and Blogs . More than 90,000 copies have been sold and is available in nine languages. There are more than 125 self-organized HubSpot user groups. We also have over 1.2 million followers and fans among Twitter, Facebook and LinkedIn as of December 31, 2014, including approximately 116,000 members of LinkedIn who belong to our inbound marketers group. Our INBOUND conference is one of the largest inbound industry conference events with attendance increasing from 1,100 in 2011 to over 10,000 registered attendees in 2014. We currently hold the world record for the largest online marketing seminar with 10,899 live participants. We believe that it is inherently hard to replicate the number of websites that link to us, the volume of useful content we have published, our large social media following, the breadth of our search engine rankings and our overall brand strength because these assets cannot be easily purchased or built.

Large and Growing Agency Partner Program. More than 2,200 agencies partner with us for the value of our platform to their business including being able to offer new inbound marketing and sales services to their clients which can grow their revenue per customer, attract new customers and increase the portion of their clients on a retainer relationship. We believe that the wide adoption of our platform in the marketing agency industry is evidence that we are becoming an industry standard. Marketing agency partners and customers referred to us by our marketing agency partners represented approximately 44% of our customers as of December 31, 2014 and 34% of our revenue for the year ended December 31, 2014. These marketing agency partners help us to promote the vision of the inbound experience, efficiently reach new mid-market businesses at scale and provide our mutual customers with more diverse and higher-touch services.

Mid-Market Focus. We believe we have significant competitive advantages reaching mid-market businesses and efficiently reach this market at scale as a result of our proven inbound go-to-market approach and our agency partner channel. In 2014, over 82% of the new leads we generated and over 93% of our new customers were from inbound marketing and did not have any advertising costs associated with them. We believe our large inbound marketing footprint and agency partner program provide competitive advantages in reaching mid-market businesses.

Powerful Network Effects. We have built a large and growing ecosystem around our platform and company. We have built what we believe is the largest engaged audience in our industry, which now comprises more than 2 million people between our blog subscribers, Twitter followers, Facebook fans, LinkedIn connections and our opt-in email list. We have attracted more than 2,200 marketing agency partners worldwide who promote our brand and extend our marketing and sales reach. Thousands of our customers integrate third-party applications with our platform using our built-in connectors and third-party developer partners. We have trained and certified more than 10,000 marketers on inbound marketing. Our annual INBOUND conference attracted more than 10,000 registered attendees in 2014. We believe this ecosystem drives more businesses and professionals to embrace the inbound playbook. As our engaged audience grows, more agencies partner with us, more third-party developers integrate their applications with our platform, and more professionals complete our certification programs, all of which drive more businesses to adopt our platform.

Our Growth Strategy

The key elements to our growth strategy are:

Grow Our U.S. Customer Base. The market for our platform is large and underserved. Mid-market businesses are particularly underserved by existing point application vendors and often lack sufficient resources

8

to implement complex solutions. Our all-in-one platform allows mid-market businesses to efficiently adopt and execute an effective inbound marketing strategy to help them expand and grow. We will continue to leverage our inbound go-to-market approach and our network of marketing agency partners to keep growing our domestic business.

Increase Revenue from Existing Customers. With 13,607 customers in more than 90 countries spanning many industries, we believe we have a significant opportunity to increase revenue from our existing customers. We plan to increase revenue from our existing customers by expanding their use of our platform, selling to other parts of their organizations and upselling additional offerings and features. Our scalable pricing model allows us to capture more spend as our customers grow, increase the number of their customers and prospects managed on our platform, and require additional functionality available from our higher price tiers and add-ons, providing us with a substantial opportunity to increase the lifetime value of our customer relationships.

Keep Expanding Internationally. There is a significant opportunity for our inbound platform outside of the United States. As of December 31, 2014, approximately 22% of our customers were located outside of the United States and these customers generated approximately 21% of our total revenue for the year ended December 31, 2014, but we sell to those foreign customers from our U.S., Ireland, and Australia based operations. We intend to grow our presence in international markets through additional investments in local sales, marketing and professional service capabilities, as well as by leveraging our agency partner network. We opened our first international office focused on the European market in January 2013 and our second international office focused on the Asia Pacific market in Sydney, Australia in August 2014. We already have significant website traffic from regions outside the United States and we believe that markets outside the United States represent a significant growth opportunity.

Continue to Innovate and Expand Our Platform. Mid-market businesses are increasingly realizing the value of having an integrated marketing, sales and service platform. We believe we are well positioned to capitalize on this opportunity by introducing new products and applications to extend the functionality of our platform. For example, in 2013, we launched our Sidekick product designed to empower sales professionals to benefit from real-time interaction data to engage with their most relevant prospects.

Selectively Pursue Acquisitions. We plan to selectively pursue acquisitions of complementary businesses, technologies and teams that would allow us to add new features and functionalities to our platform and accelerate the pace of our innovation.

Our Products

All-in-one Marketing and Sales Platform

Designed from the ground up to deliver an inbound experience, our software platform enables businesses to attract, engage and delight customers. At the core of our platform is a single inbound database of customer information. This allows a complete view of customer interactions across all of our integrated applications, giving our platform substantial power. This integration makes it possible to personalize web content, social media engagement and email messages across devices, including mobile. The integrated applications on our platform have a common user interface, are accessed through a single login and are based on our inbound database. The following diagram sets forth the principal applications of our platform and how businesses use them in the various parts of the marketing and sales funnel.

Content Optimization System (COS). Our COS applications are part content management system and part personalization engine, enabling businesses to create new and edit existing web content while also personalizing their websites for different visitors and optimizing their websites to convert more visitors into leads and customers. Features include:

• Business Blogging —Designed for lead generation, our blog includes “get-as-you-type” SEO tips for how to improve articles, built-in social media integration to automatically post new articles in social media, mobile optimization that automatically optimizes posts for smartphones and tablets, and integrated analytics that allow marketers to see the performance of each post and their blogging overall.

• Website Pages —A flexible system to build modern websites with responsive design, which means websites are dynamically optimized for desktops, laptops, tablets and smartphones without the need for maintaining different website versions for each device type.

• Smart Content —Display customized text, images or other content to customers to provide a personalized experience based on any information stored in the inbound database.

Search Engine Optimization (SEO). Our SEO applications are tightly integrated into all of the content applications on our platform, making it easy to select the right keywords and optimize content to attract more visitors from search engines. Features include:

• Keywords —Identify which search terms are used more frequently and are better opportunities, and track results on each keyword.

• Page Performance —Generate automated diagnostic reports about which web pages are not properly optimized, including instructions on what to fix and how to fix it.

Social Inbox. Our social media applications allow businesses to monitor, publish and track social media across Facebook, LinkedIn, Twitter and Google+, leveraging the personalized information about each contact stored in the inbound database. Features include:

• Publishing —Schedule messages to be posted at any time in multiple Twitter accounts, as well as personal pages, business pages and groups on LinkedIn, Google+ and Facebook.

• Personalization —Dynamically personalize the content of emails including the sender, images and text based on the information about the recipient in the inbound database.

Product Packaging

In 2012, we began pricing and packaging our products based on product plans, number of contacts and add-ons. We sell three product plans, each of which includes key functionality of our core platform but also includes different applications to meet the needs of the various businesses we serve.

HubSpot Basic is our entry level plan starting at $2,400 per year. This plan includes our platform with applications such as blogging, landing pages, Social Inbox, email marketing, and analytics and reporting.

HubSpot Pro is our plan for professional marketers starting at $9,600 per year. This plan includes the platform with all the applications included in HubSpot Basic plus more advanced applications such as CRM integration, marketing automation and smart content.

HubSpot Enterprise is an advanced plan for marketing teams starting at $28,800 per year. This plan includes our platform with all the applications included in HubSpot Pro, plus more sophisticated applications such as A/B testing and optimization, tracking custom events and advanced reporting capabilities.

Pricing for all plans is on a subscription basis and customers pay additional fees above the starting prices based on how many contacts will be stored and tracked in the inbound database. We generate additional revenue based on the purchase of additional subscriptions and applications and the number of account users, subdomains and website visits.

Add Ons. We also sell applications that are not included in any of our three plans on an add-on basis.

• CMS allows a business to build, edit and manage an entire website on our platform. CMS has a per-month fee in addition to the fee paid for our inbound platform, which is required to use CMS.

• Sidekick notifies salespeople of the activity of their most highly engaged potential customers. The Starter version is free and includes a limited number of notifications and features, while the Power User version has a per-user fee and includes unlimited notifications and all available features. We had more than 300,000 monthly active users with a free or paid Sidekick account for our Sidekick product during December 31, 2014.

Our Services

We complement our product offerings with professional services and support. The majority of our services and support is offered over the phone and via web meeting technology rather than in-person, which is a more efficient business model for us and more cost-effective for our customers.

Professional Services. We offer professional services to educate and train customers on how to leverage our software platform and inbound marketing methodology to transform how their business attracts, engages and delights customers. Depending on which product plan and professional services a customer buys, it either receives group training and education in online or in-person classes or one-on-one training and advice from one of our implementation specialists by phone and web meeting. Our professional services are also available to customers who need additional assistance on a one-time or ongoing basis for an additional fee.

Support. In addition to assistance provided by our online articles and customer discussion forums, we offer phone and email-based support staffed in the United States and Ireland, which is included in the cost of a subscription. We strive to maintain an exceptional quality of customer service. We continuously monitor key customer service metrics such as phone hold time, ticket response time and ticket resolution rates, and we monitor the customer satisfaction of our customer support interactions. We believe our customer support is an important reason why businesses choose our platform and recommend it to their colleagues.

Our Customers

We have 13,607 customers in more than 90 countries, representing many industries. No single customer represented more than 1% of our revenue in 2012, 2013 or 2014. The following sets forth a list of representative customers:

By using our platform to deliver an inbound experience, many customers benefit from substantial increases in web traffic, leads and new customers, leading to a significant return on investment. The case studies below illustrate the results our customers have achieved by using our platform.

ShoreTel

Situation: ShoreTel is a leading provider of IP phone systems and unified communications solutions. ShoreTel was frustrated that “last generation” marketing tools impeded its ability to execute its marketing strategies. The main application ShoreTel used was an enterprise marketing automation application from one of the leading traditional vendors, which it found to be inflexible, slow and not user-friendly.

14

Solution: The ShoreTel team evaluated a variety of leading marketing application vendors with a goal of finding a platform that was both easy to use and designed to help them offer an inbound experience. ShoreTel chose our platform over competitive marketing applications, because it found our platform to be the most comprehensive and complete, the easiest to use and the only platform designed to embrace an inbound experience.

Results: ShoreTel quickly saw the value of using our platform. Within the first two months, it was able to iterate and test new marketing automation workflows that led to a 100% increase in email nurturing response rates. After one year of using our platform, ShoreTel reported the following gains (year-over-year): 60% increase in traffic, 36% increase in leads and 110% increase in qualified leads.

AmeriFirst Home Mortgage

Situation: AmeriFirst Home Mortgage is a community mortgage banker specializing in lending to first-time home buyers. In business more than 25 years, AmeriFirst’s main challenge was taking the person to person business tactics it had always done and adapting them for the Internet era. AmeriFirst’s website served as an “online brochure” for more than a decade, but was not an effective channel to drive more business, and AmeriFirst struggled with using multiple point applications for its marketing and sales. AmeriFirst wanted to transform its web presence into a more efficient channel for growing its business and drive better ROI.

Solution: AmeriFirst moved from a variety of point applications to our platform and implemented an inbound experience throughout its marketing and sales functions. AmeriFirst uses our platform for blogging, SEO, social media, marketing automation and personalized content to attract more web visitors, engage its leads and provide more qualified sales opportunities to its sales team. AmeriFirst cut spending on traditional tactics like direct mail and phonebook advertising, and instead used our platform to focus on inbound marketing and sales that led to a better experience for AmeriFirst’s customers and better ROI for its business.

Results: After six months of using our platform, AmeriFirst reported that its monthly website traffic increased by 120% and monthly leads coming from its website grew more than 20-fold. After one year using our platform, AmeriFirst reported that its monthly web traffic grew 380% and leads grew by a factor of more than 51. After two years using our platform, AmeriFirst reported more than a 16-fold increase in monthly website traffic rates and 90 times as many leads coming from its website as compared to before. AmeriFirst attributed 147 new customers in the first year and 266 customers in the second year to its inbound marketing activities powered by our platform.

New Breed Marketing

Situation: New Breed Marketing was a traditional marketing agency specializing in branding and website design, though it would take on most marketing projects that came its way. New Breed lacked clear specialization, and the difficulty in proving long-term ROI to its clients left New Breed juggling numerous short-term projects rather than getting the long-term, retainer-based clients it desired. New Breed needed to transform its model to focus on longer-term client relationships. New Breed wanted a platform that would manage its own marketing as well as the marketing it did for clients all in one place, and a way to offer inbound marketing and sales services on a retainer basis to its clients.

Solution: New Breed used our platform to manage a client’s entire marketing strategy with all of the applications and reporting available in one place. By embracing an inbound experience and offering a new set of inbound marketing and sales services, New Breed was better positioned to be a long-term, strategic partner for its clients, increasing the amount of retainer business and attracting new clients as well, both of which improved cash flow and profitability. With our platform, New Breed could better prove the ROI of a client’s investment in its agency, shifting New Breed’s status from tactical vendor to strategic partner.

Results: Beyond having the tools to prove ROI and technology that enhances its value proposition, New Breed Marketing has seen its own gains with re-launching on the COS. Within four months of launching its new website built on our content management application and implementing the rest of our platform, New Breed reported a 99% increase in monthly traffic, 61% increase in visitor to lead conversion and 100% increase in lead to customer conversion.

The data in the case studies set forth above as to increased visits, leads, qualified leads and conversions following implementation of our platform does not necessarily mean that our platform was the only factor causing such increases.

Our Technology

13,607 customers have chosen us as their marketing and sales platform, which we architected and built to be secure, highly distributed and highly scalable. Since our founding, we have embraced rapid, iterative product development lifecycles, cloud automation and open-source technologies, including big data platforms, to power marketing and sales programs and provide insights not previously possible or available.

Our platform is a multi-tenant, single code-based, globally available software-as-a-service delivered through web browsers or mobile applications. Our commitment to a highly available, reliable and scalable platform for businesses of all sizes is accomplished through the use of these technologies.

Modern Database Architecture. We process billions of data points weekly across various channels, including social media, email, SEO and website visits, and continue to drive nearly real-time analytics across these channels. This is possible because we built our database from the ground up using distributed big data technologies such as HBase and Hadoop to both process and analyze the large amounts of data we collect in our inbound database. Using modern database technologies, we can provide actionable insights across disparate data-sets in a manner not easily achievable or cost effectively, at scale or efficiently, with traditional databases or platform architectures.

Agility. Our infrastructure and development and software release processes allow us to update our platform for specific groups of customers or our entire customer base at any time. This means we can rapidly innovate and deliver new functionality frequently, without waiting for quarterly or annual release cycles. We typically deploy updates to our software platform hundreds of times a week, enabling us to gather immediate customer feedback and improve our product quickly and continuously.

Cost leverage. Because our platform was built on an almost exclusive footprint of open-source software and designed to operate in cloud-based data-centers, we have benefited from large-scale price reductions by these cloud computing service providers as they continue to innovate and compete for market share. As our processing volume continues to grow, we continue to receive larger volume discounts on a per-unit basis such as cost for storage, bandwidth and computing capacity. We also believe that our extensive use, and contribution to, open-source software will provide additional leverage as we scale our platform and infrastructure.

Scalability. By leveraging leading cloud infrastructure providers along with our automated technology stack, we are able to scale workloads of varying sizes at any time. This allows us to handle customers of all sizes and demands without traditional operational limitations such as network bandwidth, computing cycles, or storage capacity as we can scale our platform on-demand.

Reliability. Our platform’s uptime during 2014 exceeded 99.9% while we delivered hundreds of product improvements through thousands of software releases in a continuous software delivery cycle. Customer data is distributed and processed across multiple data centers within a region to provide redundancy. We built our platform on a distributed computing architecture with no single points of failure and we operate across data-center boundaries daily. In addition to data-center level redundancy, this architecture supports multiple live copies of each data set along with snapshot capabilities for faster, point-in-time data recovery instead of traditional backup and restore methodologies.

Security. We leverage industry standard network and perimeter defense technologies, DDoS protection systems (including web application firewalls) and enterprise grade DNS services across multiple vendors. Our data-center providers operate and certify to high industry compliance levels. Due to the broad footprint of our customer base, we regularly test and evaluate our platform with trusted third-party vendors to ensure the security and integrity of our services.

As of December 31, 2014 we had 132 employees in our research and development organization. Our research and development expenses were $25.6 million in 2014, $15.0 million in 2013 and $10.6 million in 2012.

Marketing and Sales

We believe we are a global leader in implementing an inbound experience in marketing and sales. We believe that our marketing and sales model provides us with a competitive advantage, especially when targeting mid-market businesses, because we can attract and engage these businesses efficiently and at scale.

Inbound Marketing. Our marketing team focuses on inbound marketing and attracts over 40,000 new leads per month through our industry-leading blog and other content, free tools, large social media following, high search engine rankings and personalized website and email content. Inbound sources generated over 93% of our new customers and over 82% of new leads during 2014. We believe most companies of our size and scale typically have a far lower volume of lead generation with a much larger share of it coming from traditional advertising methods.

Inbound Direct Sales. Our sales representatives are based in our offices in Cambridge, Massachusetts and Dublin, Ireland and use phone, email and web meetings to interact with prospects and customers. The vast majority of revenue generated by our sales representatives originates with inbound leads produced by our marketing efforts.

Inbound Channel Sales. In addition to our direct sales team, we have sales representatives that manage relationships with our worldwide network of marketing agency partners who both use our platform for their own businesses and also, on a commissioned basis, refer customers to us. These marketing agencies partner with us not only to leverage our software platform and educational resources, but also to build their own business by offering new services and shifting their revenue mix to include more retainer-based business with a recurring revenue stream.

Employees and Culture

Transforming the business world to embrace the inbound experience requires a truly remarkable team. From the very beginning, our company was founded on a fundamental belief in radical transparency, individual autonomy and enlightened empathy.

To that end, we published our “Culture Code,” a document codifying how we went about building a business that employees, customers and partners alike truly love. Our Culture Code slide deck has been viewed more than 1.5 million times on LinkedIn’s SlideShare and become an important element of our recruiting efforts. The seven core principles of our Culture Code are:

• We are maniacal about our mission and our metrics. Our mission is to make the world inbound and transform how organizations attract, engage and delight their customers.

• We empower every employee, at every level, to “Solve for the Customer”. We solve for the customer, company, team and self, in that order.

• We are radically transparent. We believe that power is gained by sharing knowledge, not hoarding it and we share nearly all business information with all of our employees no matter their title or position.

• We give ourselves the autonomy to be awesome. We trust and empower each employee to use good judgment, and believe that results should matter more than when or where they are produced and that influence should be independent of hierarchy.

• We are unreasonably picky about our peers. We value people who are humble, effective and predisposed to action, adaptable to charge, remarkable standouts and transparent with others and with themselves.

17

• We invest in individual mastery and market value. We want to be as proud of the people we build as we are of the company we build. We believe in investing in our people with ongoing learning, broad exposure and big challenges.

• We constantly question the status quo. We believe that remarkable outcomes rarely result from modest risk and we’d rather be failing frequently than never trying new things.

We take great pride in recruiting and retaining people with HEART: Humble, Effective, Adaptable, Remarkable and Transparent employees at every level of our company who want to transform the business world with inbound. We’ve been recognized as one of Boston’s Best Places to Work, a Best Place to Work for Recent Grads and one of Glassdoor’s Most Difficult Companies to Interview, and our policies on employee autonomy and transparency have been widely profiled in the media. At the end of the day, however, we do not just talk about culture, we measure it, just as we do the rest of our business. Our founders review our quarterly employee feedback metrics and surveys, respond to them and use them in executive team evaluations.

As of December 31, 2014 we had 785 full-time employees. Of these employees, 680 are based in the United States, 97 are located in Ireland, and 8 are located in Australia.

Competition

Our market is evolving, highly competitive and fragmented, and we expect competition to increase in the future. We believe the principal competitive factors in our market are:

• vision for the market and product strategy and pace of innovation;

• inbound marketing focus and domain expertise;

• integrated all-in-one platform;

• breadth and depth of product functionality;

• ease of use;

• scalable, open architecture;

• time to value and total cost of ownership;

• integration with third-party applications and data sources; and

• name recognition and brand reputation.

We believe we complete favorably with respect to all of these factors.

We face intense competition from other software companies that develop marketing software and from marketing services companies that provide interactive marketing services. Our competitors offer various point applications that provide certain functions and features that we provide, including:

• cloud-based marketing automation providers;

• email marketing software vendors;

• sales force automation and CRM software vendors; and

• large-scale enterprise suites.

In addition, instead of using our platform, some prospective customers may elect to combine disparate point applications, such as content management, marketing automation, analytics and social media management. We expect that new competitors, such as enterprise software vendors that have traditionally focused on enterprise resource planning or other applications supporting back office functions, will develop and introduce, or acquire, applications serving customer-facing and other front office functions.

18

Intellectual Property

Our ability to protect our intellectual property, including our technology, will be an important factor in the success and continued growth of our business. We protect our intellectual property through trade secrets law, copyrights, trademarks and contracts. Some of our technology relies upon third-party licensed intellectual property.

In addition to the foregoing, we have established business procedures designed to maintain the confidentiality of our proprietary information, including the use of confidentiality agreements and assignment of inventions agreements with employees, independent contractors, consultants and companies with which we conduct business.

Financial Information About Segments

The Company operates as one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is regularly evaluated by the chief operating decision makers (“CODMs”), which are the Company’s chief executive officer and chief operating officer, in deciding how to allocate resources and assess performance. The Company’s CODMs evaluate the Company’s financial information and resources and assess the performance of these resources on a consolidated basis. Since the Company operates in one operating segment, all required financial segment information can be found in the consolidated financial statements. See Footnote 7 within the consolidated financial statements for information by geographic area.

Available Information

The SEC also maintains a website, www.sec.gov, that contains reports and other information regarding issuers that file electronically with the SEC. The public may read and copy any files with the SEC Public Reference Room at 100 F Street, NE, Washington, DC 20549. The public may obtain information on the operation of the Public Reference Room by calling 1-800-SEC-0330. We are not, however, including the information contained on our website, or information that may be accessed through links on our website, as part of, or incorporating such information by reference into, this Annual Report on Form 10-K.

ITEM 1A. RISK FACTORS

An investment in our common stock involves a high degree of risk. You should carefully consider the risks described below and the other information in this Annual Report on Form 10-K and in our other public filings before making an investment decision. Our business, prospects, financial condition, or operating results could be harmed by any of these risks, as well as other risks not currently known to us or that we currently consider immaterial. If any of such risks and uncertainties actually occurs, our business, financial condition or operating results could differ materially from the plans, projections and other forward-looking statements included in the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in this report and in our other public filings. The trading price of our common stock could decline due to any of these risks, and, as a result, you may lose all or part of your investment.

Risks Related to Our Business and Strategy

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

We generated net losses of $48.2 million in 2014, of $34.3 million in 2013, and of $18.8 million in 2012. As of December 31, 2014, we had an accumulated deficit of $154.3 million. We will need to generate and sustain increased revenue levels in future periods to become profitable, and, even if we do, we may not be able to maintain or increase our level of profitability. We intend to continue to expend significant funds to grow our

19

marketing and sales operations, develop and enhance our inbound platform, scale our data center infrastructure and services capabilities and expand into new markets. Our efforts to grow our business may be more costly than we expect, and we may not be able to increase our revenue enough to offset our higher operating expenses. We may incur significant losses in the future for a number of reasons, including the other risks described in this Annual Report on Form 10-K, and unforeseen expenses, difficulties, complications and delays and other unknown events. If we are unable to achieve and sustain profitability, the market price of our common stock may significantly decrease.

We are dependent upon customer renewals, the addition of new customers and the continued growth of the market for an inbound platform.

We derive, and expect to continue to derive, a substantial portion of our revenue from the sale of subscriptions to our inbound marketing platform. The market for inbound marketing and sales products is still evolving, and competitive dynamics may cause pricing levels to change as the market matures and as existing and new market participants introduce new types of point applications and different approaches to enable businesses to address their respective needs. As a result, we may be forced to reduce the prices we charge for our platform and may be unable to renew existing customer agreements or enter into new customer agreements at the same prices and upon the same terms that we have historically.

Our subscription renewal rates may decrease, and any decrease could harm our future revenue and operating results.

Our customers have no obligation to renew their subscriptions for our platform after the expiration of their subscription periods, substantially all of which are one year or less. In addition, our customers may seek to renew for lower subscription amounts or for shorter contract lengths. Also, customers may choose not to renew their subscriptions for a variety of reasons, including an inability or failure on the part of a customer to create blogging, social media and other content necessary to realize the benefits of our platform. Our renewal rates may decline or fluctuate as a result of a number of factors, including limited customer resources, pricing changes, adoption and utilization of our platform and add-on applications by our customers, adoption of our new products (such as our CRM and Sidekick products launched in September 2014), customer satisfaction with our platform, the acquisition of our customers by other companies and deteriorating general economic conditions. If our customers do not renew their subscriptions for our platform or decrease the amount they spend with us, our revenue will decline and our business will suffer.

We face significant competition from both established and new companies offering marketing and sales software and other related applications, as well as internally developed software, which may harm our ability to add new customers, retain existing customers and grow our business.

The marketing and sales software market is evolving, highly competitive and significantly fragmented. With the introduction of new technologies and the potential entry of new competitors into the market, we expect competition to persist and intensify in the future, which could harm our ability to increase sales, maintain or increase renewals and maintain our prices.

We face intense competition from other software companies that develop marketing and sales software and from marketing services companies that provide interactive marketing services. Competition could significantly impede our ability to sell subscriptions to our inbound marketing and sales platform on terms favorable to us. Our current and potential competitors may develop and market new technologies that render our existing or future products less competitive, or obsolete. In addition, if these competitors develop products with similar or superior functionality to our platform, we may need to decrease the prices or accept less favorable terms for our platform subscriptions in order to remain competitive. If we are unable to maintain our pricing due to competitive pressures, our margins will be reduced and our operating results will be negatively affected.

Our competitors include:

• cloud-based marketing automation providers;

20

• email marketing software vendors;

• sales force automation and CRM software vendors; and

• large-scale enterprise suites.

In addition, instead of using our platform, some prospective customers may elect to combine disparate point applications, such as content management, marketing automation, CRM, analytics and social media management. We expect that new competitors, such as enterprise software vendors that have traditionally focused on enterprise resource planning or other applications supporting back office functions, will develop and introduce applications serving customer-facing and other front office functions. This development could have an adverse effect on our business, operating results and financial condition. In addition, sales force automation and CRM system vendors could acquire or develop applications that compete with our marketing software offerings. Some of these companies have acquired social media marketing and other marketing software providers to integrate with their broader offerings.

Our current and potential competitors may have significantly more financial, technical, marketing and other resources than we have, be able to devote greater resources to the development, promotion, sale and support of their products and services, may have more extensive customer bases and broader customer relationships than we have, and may have longer operating histories and greater name recognition than we have. As a result, these competitors may respond faster to new technologies and undertake more extensive marketing campaigns for their products. In a few cases, these vendors may also be able to offer marketing and sales software at little or no additional cost by bundling it with their existing suite of applications. To the extent any of our competitors has existing relationships with potential customers for either marketing software or other applications, those customers may be unwilling to purchase our platform because of their existing relationships with our competitor. If we are unable to compete with such companies, the demand for our inbound platform could substantially decline.

In addition, if one or more of our competitors were to merge or partner with another of our competitors, our ability to compete effectively could be adversely affected. Our competitors may also establish or strengthen cooperative relationships with our current or future strategic distribution and technology partners or other parties with whom we have relationships, thereby limiting our ability to promote and implement our platform. We may not be able to compete successfully against current or future competitors, and competitive pressures may harm our business, operating results and financial condition.

We have experienced rapid growth and organizational change in recent periods and expect continued future growth. If we fail to manage our growth effectively, we may be unable to execute our business plan, maintain high levels of service or address competitive challenges adequately.

Our head count and operations have grown substantially. For example, we had 785 full-time employees as of December 31, 2014, as compared with 668 as of December 31, 2013. We opened our first international office in Dublin, Ireland in January 2013, and a second international office in Sydney, Australia in August 2014. This growth has placed, and will continue to place, a significant strain on our management, administrative, operational and financial infrastructure. We anticipate further growth will be required to address increases in our product offerings and continued expansion. Our success will depend in part upon our ability to recruit, hire, train, manage and integrate a significant number of qualified managers, technical personnel and employees in specialized roles within our company, including in technology, sales and marketing. If our new employees perform poorly, or if we are unsuccessful in recruiting, hiring, training, managing and integrating these new employees, or retaining these or our existing employees, our business may suffer.

In addition, to manage the expected continued growth of our head count, operations and geographic expansion, we will need to continue to improve our information technology infrastructure, operational, financial and management systems and procedures. Our anticipated additional head count and capital investments will increase our costs, which will make it more difficult for us to address any future revenue shortfalls by reducing expenses in the short term. If we fail to successfully manage our growth, we will be unable to successfully execute our business plan, which could have a negative impact on our business, results of operations or financial condition.

Failure to effectively develop and expand our marketing and sales capabilities could harm our ability to increase our customer base and achieve broader market acceptance of our platform.

To increase total customers and achieve broader market acceptance of our inbound platform, we will need to expand our marketing and sales operations, including our sales force and third-party channel partners. We will continue to dedicate significant resources to inbound sales and marketing programs. The effectiveness of our inbound sales and marketing and third-party channel partners has varied over time and may vary in the future and depends on our ability to maintain and improve our inbound platform. All of these efforts will require us to invest significant financial and other resources. Our business will be seriously harmed if our efforts do not generate a correspondingly significant increase in revenue. We may not achieve anticipated revenue growth from expanding our sales force if we are unable to hire, develop and retain talented sales personnel, if our new sales personnel are unable to achieve desired productivity levels in a reasonable period of time or if our sales and marketing programs are not effective.

The rate of growth of our business depends on the continued participation and level of service of our marketing agency partners.

We rely on our marketing agency partners to provide certain services to our customers, as well as pursue sales of our inbound platform to customers. Marketing agency partners and customers referred to us by our marketing agency partners represented approximately 44% of our customers as of December 31, 2014, and 34% of our revenue for the year ended December 31, 2014. To the extent we do not attract new marketing agency partners, or existing or new marketing agency partners do not refer a growing number of customers to us, our revenue and operating results would be harmed. In addition, if our marketing agency partners do not continue to provide services to our customers, we would be required to provide such services ourselves either by expanding our internal team or engaging other third-party providers, which would increase our operating costs.

If we cannot maintain our company culture as we grow, we could lose the innovation, teamwork, passion and focus on execution that we believe contribute to our success and our business may be harmed.

We believe that a critical component to our success has been our company culture, which is based on transparency and personal autonomy. We have invested substantial time and resources in building our team within this company culture. Any failure to preserve our culture could negatively affect our ability to retain and recruit personnel and to effectively focus on and pursue our corporate objectives. As we grow as and develop the infrastructure of a public company, we may find it difficult to maintain these important aspects of our company culture. If we fail to maintain our company culture, our business may be adversely impacted.

If we fail to maintain our inbound thought leadership position, our business may suffer.

We believe that maintaining our thought leadership position in inbound marketing, sales and services is an important element in attracting new customers. We devote significant resources to develop and maintain our thought leadership position, with a focus on identifying and interpreting emerging trends in the inbound experience, shaping and guiding industry dialog and creating and sharing the best inbound practices. Our activities related to developing and maintaining our thought leadership may not yield increased revenue, and even if they do, any increased revenue may not offset the expenses we incurred in such effort. We rely upon the continued services of our management and employees with domain expertise with inbound marketing, sales and services, and the loss of any key employees in this area could harm our competitive position and reputation. If we fail to successfully grow and maintain our thought leadership position, we may not attract enough new customers or retain our existing customers, and our business could suffer.

If we fail to further enhance our brand and maintain our existing strong brand awareness, our ability to expand our customer base will be impaired and our financial condition may suffer.

We believe that our development of the HubSpot brand is critical to achieving widespread awareness of our existing and future inbound experience solutions, and, as a result, is important to attracting new customers and maintaining existing customers. In the past, our efforts to build our brand have involved significant expenses, and we believe that this investment has resulted in strong brand recognition in the business-to-business, or B2B,

22

market. Successful promotion and maintenance of our brands will depend largely on the effectiveness of our marketing efforts and on our ability to provide a reliable and useful inbound platform at competitive prices. Brand promotion activities may not yield increased revenue, and even if they do, any increased revenue may not offset the expenses we incurred in building our brand. If we fail to successfully promote and maintain our brand, our business could suffer.

If we fail to adapt and respond effectively to rapidly changing technology, evolving industry standards and changing customer needs or requirements, our inbound platform may become less competitive.

Our future success depends on our ability to adapt and innovate our inbound platform. To attract new customers and increase revenue from existing customers, we need to continue to enhance and improve our offerings to meet customer needs at prices that our customers are willing to pay. Such efforts will require adding new functionality and responding to technological advancements, which will increase our research and development costs. If we are unable to develop new applications that address our customers’ needs, or to enhance and improve our platform in a timely manner, we may not be able to maintain or increase market acceptance of our platform. Our ability to grow is also subject to the risk of future disruptive technologies. Access and use of our inbound platform is provided via the cloud, which, itself, was disruptive to the previous enterprise software model. If new technologies emerge that are able to deliver inbound marketing software and related applications at lower prices, more efficiently, more conveniently or more securely, such technologies could adversely affect our ability to compete.

We rely on our management team and other key employees, and the loss of one or more key employees could harm our business.

Our success and future growth depend upon the continued services of our management team, including our co-founders, Brian Halligan and Dharmesh Shah, and other key employees in the areas of research and development, marketing, sales, services and general and administrative functions. From time to time, there may be changes in our management team resulting from the hiring or departure of executives, which could disrupt our business. We also are dependent on the continued service of our existing software engineers and information technology personnel because of the complexity of our platform, technologies and infrastructure. We may terminate any employee’s employment at any time, with or without cause, and any employee may resign at any time, with or without cause. We do not have employment agreements with any of our key personnel. The loss of one or more of our key employees could harm our business.

The failure to attract and retain additional qualified personnel could prevent us from executing our business strategy.

To execute our business strategy, we must attract and retain highly qualified personnel. In particular, we compete with many other companies for software developers with high levels of experience in designing, developing and managing cloud-based software, as well as for skilled information technology, marketing, sales and operations professionals, and we may not be successful in attracting and retaining the professionals we need. Also, inbound sales, marketing and services domain experts are very important to our success and are difficult to replace. We have from time to time in the past experienced, and we expect to continue to experience in the future, difficulty in hiring and difficulty in retaining highly skilled employees with appropriate qualifications. In particular, we have experienced a competitive hiring environment in the Greater Boston area, where we are headquartered. Many of the companies with which we compete for experienced personnel have greater resources than we do. In addition, in making employment decisions, particularly in the software industry, job candidates often consider the value of the stock options or other equity incentives they are to receive in connection with their employment. If the price of our stock declines, or experiences significant volatility, our ability to attract or retain key employees will be adversely affected. If we fail to attract new personnel or fail to retain and motivate our current personnel, our growth prospects could be severely harmed.

23

If we fail to offer high-quality customer support, our business and reputation may suffer.

High-quality education, training and customer support are important for the successful marketing, sale and use of our inbound platform and for the renewal of existing customers. Providing this education, training and support requires that our personnel who manage our online training resource, HubSpot Academy, or provide customer support have specific inbound experience domain knowledge and expertise, making it more difficult for us to hire qualified personnel and to scale up our support operations. The importance of high-quality customer support will increase as we expand our business and pursue new customers. If we do not help our customers use multiple applications within our inbound platform and provide effective ongoing support, our ability to sell additional functionality and services to, or to retain, existing customers may suffer and our reputation with existing or potential customers may be harmed.

We may not be able to scale our business quickly enough to meet our customers’ growing needs and if we are not able to grow efficiently, our operating results could be harmed.

As usage of our inbound platform grows and as customers use our platform for additional inbound applications, such as sales and services, we will need to devote additional resources to improving our application architecture, integrating with third-party systems and maintaining infrastructure performance. In addition, we will need to appropriately scale our internal business systems and our services organization, including customer support and professional services, to serve our growing customer base, particularly as our customer demographics change over time. Any failure of or delay in these efforts could cause impaired system performance and reduced customer satisfaction. These issues could reduce the attractiveness of our inbound platform to customers, resulting in decreased sales to new customers, lower renewal rates by existing customers, the issuance of service credits, or requested refunds, which could impede our revenue growth and harm our reputation. Even if we are able to upgrade our systems and expand our staff, any such expansion will be expensive and complex, requiring management’s time and attention. We could also face inefficiencies or operational failures as a result of our efforts to scale our infrastructure. Moreover, there are inherent risks associated with upgrading, improving and expanding our information technology systems. We cannot be sure that the expansion and improvements to our infrastructure and systems will be fully or effectively implemented on a timely basis, if at all. These efforts may reduce revenue and our margins and adversely affect our financial results.

Our ability to introduce new products and features is dependent on adequate research and development resources. If we do not adequately fund our research and development efforts, we may not be able to compete effectively and our business and operating results may be harmed.

To remain competitive, we must continue to develop new product offerings, applications, features and enhancements to our existing inbound platform. Maintaining adequate research and development personnel and resources to meet the demands of the market is essential. If we are unable to develop our platform internally due to certain constraints, such as high employee turnover, lack of management ability or a lack of other research and development resources, we may miss market opportunities. Further, many of our competitors expend a considerably greater amount of funds on their research and development programs, and those that do not may be acquired by larger companies that would allocate greater resources to our competitors’ research and development programs. Our failure to maintain adequate research and development resources or to compete effectively with the research and development programs of our competitors could materially adversely affect our business.

Changes in the sizes or types of businesses that purchase our platform or in the applications within our inbound platform purchased or used by our customers could negatively affect our operating results.

Our strategy is to sell subscriptions to our inbound platform to mid-sized businesses, but we have sold and will continue to sell to organizations ranging from small businesses to enterprises. Our gross margins can vary depending on numerous factors related to the implementation and use of our inbound platform, including the sophistication and intensity of our customers’ use of our platform and the level of professional services and

24

support required by a customer. Sales to enterprise customers may entail longer sales cycles and more significant selling efforts. Selling to small businesses may involve greater credit risk and uncertainty. If there are changes in the mix of businesses that purchase our platform or the mix of the product plans purchased by our customers, our gross margins could decrease and our operating results could be adversely affected.

We have in the past completed acquisitions and may acquire or invest in other companies or technologies in the future, which could divert management’s attention, fail to meet our expectations, result in additional dilution to our stockholders, increase expenses, disrupt our operations or harm our operating results.

We have in the past acquired, and we may in the future acquire or invest in, businesses, products or technologies that we believe could complement or expand our platform, enhance our technical capabilities or otherwise offer growth opportunities. For example, in June 2011, we acquired Performable, a marketing automation provider. We may not be able to fully realize the anticipated benefits of these or any future acquisitions. The pursuit of potential acquisitions may divert the attention of management and cause us to incur various expenses related to identifying, investigating and pursuing suitable acquisitions, whether or not they are consummated.

There are inherent risks in integrating and managing acquisitions. If we acquire additional businesses, we may not be able to assimilate or integrate the acquired personnel, operations and technologies successfully or effectively manage the combined business following the acquisition and our management may be distracted from operating our business. We also may not achieve the anticipated benefits from the acquired business due to a number of factors, including: unanticipated costs or liabilities associated with the acquisition; incurrence of acquisition-related costs, which would be recognized as a current period expense; inability to generate sufficient revenue to offset acquisition or investment costs; the inability to maintain relationships with customers and partners of the acquired business; the difficulty of incorporating acquired technology and rights into our platform and of maintaining quality and security standards consistent with our brand; delays in customer purchases due to uncertainty related to any acquisition; the need to integrate or implement additional controls, procedures and policies; challenges caused by distance, language and cultural differences; harm to our existing business relationships with business partners and customers as a result of the acquisition; the potential loss of key employees; use of resources that are needed in other parts of our business and diversion of management and employee resources; the inability to recognize acquired deferred revenue in accordance with our revenue recognition policies; and use of substantial portions of our available cash or the incurrence of debt to consummate the acquisition. Acquisitions also increase the risk of unforeseen legal liability, including for potential violations of applicable law or industry rules and regulations, arising from prior or ongoing acts or omissions by the acquired businesses which are not discovered by due diligence during the acquisition process. Generally, if an acquired business fails to meet our expectations, our operating results, business and financial condition may suffer. Acquisitions could also result in dilutive issuances of equity securities or the incurrence of debt, which could adversely affect our business, results of operations or financial condition.

In addition, a significant portion of the purchase price of companies we acquire may be allocated to goodwill and other intangible assets, which must be assessed for impairment at least annually. If our acquisitions do not ultimately yield expected returns, we may be required to take charges to our operating results based on our impairment assessment process, which could harm our results of operations.

Because our long-term growth strategy involves further expansion of our sales to customers outside the United States, our business will be susceptible to risks associated with international operations.

A component of our growth strategy involves the further expansion of our operations and customer base internationally. As of December 31, 2014, approximately 22% of our customers were located outside of the United States and these customers generated approximately 21% of our total revenue for the year ended December 31, 2014. We opened our first international office in Dublin, Ireland in January 2013 and we opened

25

our second international office in Sydney, Australia in August 2014. These international offices focus primarily on sales, professional services and support. For information regarding the percentage of our revenues generated by our Ireland and Australia offices, see Note 7 of our consolidated financial statements. Our current international operations and future initiatives will involve a variety of risks, including:

• difficulties in maintaining our company culture with a dispersed and distant workforce;

• more stringent regulations relating to data security and the unauthorized use of, or access to, commercial and personal information, particularly in the European Union;

• unexpected changes in regulatory requirements, taxes or trade laws;

• differing labor regulations, especially in the European Union, where labor laws are generally more advantageous to employees as compared to the United States, including deemed hourly wage and overtime regulations in these locations;

• challenges inherent in efficiently managing an increased number of employees over large geographic distances, including the need to implement appropriate systems, policies, benefits and compliance programs;

• difficulties in managing a business in new markets with diverse cultures, languages, customs, legal systems, alternative dispute systems and regulatory systems;

• currency exchange rate fluctuations and the resulting effect on our revenue and expenses, and the cost and risk of entering into hedging transactions if we chose to do so in the future;

• limitations on our ability to reinvest earnings from operations in one country to fund the capital needs of our operations in other countries;

• limited or insufficient intellectual property protection;

• political instability or terrorist activities;

• likelihood of potential or actual violations of domestic and international anticorruption laws, such as the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act, or of U.S. and international export control and sanctions regulations, which likelihood may increase with an increase of sales or operations in foreign jurisdictions and operations in certain industries; and

• adverse tax burdens and foreign exchange controls that could make it difficult to repatriate earnings and cash.

Our limited experience in operating our business internationally increases the risk that any potential future expansion efforts that we may undertake will not be successful. If we invest substantial time and resources to expand our international operations and are unable to do so successfully and in a timely manner, our business and operating results will suffer. We continue to implement policies and procedures to facilitate our compliance with U.S. laws and regulations applicable to or arising from our international business. Inadequacies in our past or current compliance practices may increase the risk of inadvertent violations of such laws and regulations, which could lead to financial and other penalties that could damage our reputation and impose costs on us.

Interruptions or delays in service from our third-party data center providers could impair our ability to deliver our platform to our customers, resulting in customer dissatisfaction, damage to our reputation, loss of customers, limited growth and reduction in revenue.

We currently serve the majority of our platform functions from third-party data center hosting facilities operated by Amazon Web Services and located in northern Virginia. In addition, we serve ancillary functions for our customers from third-party data center hosting facilities operated by Rackspace located in Dallas, Texas, with a backup facility in Chicago, Illinois. Our operations depend, in part, on our third-party facility providers’ abilities to protect these facilities against damage or interruption from natural disasters, power or

26

telecommunications failures, criminal acts and similar events. In the event that any of our third-party facilities arrangements is terminated, or if there is a lapse of service or damage to a facility, we could experience interruptions in our platform as well as delays and additional expenses in arranging new facilities and services.

Any damage to, or failure of, the systems of our third-party providers could result in interruptions to our platform. Despite precautions taken at our data centers, the occurrence of spikes in usage volume, a natural disaster, an act of terrorism, vandalism or sabotage, a decision to close a facility without adequate notice, or other unanticipated problems at a facility could result in lengthy interruptions in the availability of our on-demand software. Even with current and planned disaster recovery arrangements, our business could be harmed. Also, in the event of damage or interruption, our insurance policies may not adequately compensate us for any losses that we may incur. These factors in turn could further reduce our revenue, subject us to liability and cause us to issue credits or cause customers to fail to renew their subscriptions, any of which could materially adversely affect our business.

We are dependent on the continued availability of third-party data hosting and transmission services.

A significant portion of our operating cost is from our third-party data hosting and transmission services. If the costs for such services increase due to vendor consolidation, regulation, contract renegotiation, or otherwise, we may not be able to increase the fees for our inbound platform or services to cover the changes. As a result, our operating results may be significantly worse than forecasted.

If we do not or cannot maintain the compatibility of our inbound platform with third-party applications that our customers use in their businesses, our revenue will decline.

A significant percentage of our customers choose to integrate our platform with certain capabilities provided by third-party software platform and application providers using application programming interfaces, or APIs, published by these providers, either as publicly available no-fee licenses or through fee-based partnership arrangements. The functionality and popularity of our inbound platform depends, in part, on our ability to integrate our platform with third-party applications and platforms, including CRM, CMS, e-commerce, call center, analytics and social media sites that our customers use and from which they obtain data. Third-party providers of applications and APIs may change the features of their applications and platforms, restrict our access to their applications and platforms, terminate or elect not to renew our partnership agreements or otherwise alter the terms governing use of their applications and APIs and access to those applications and platforms in an adverse manner. Such changes could functionally limit or terminate our ability to use these third-party applications and platforms in conjunction with our platform, which could negatively impact our offerings and harm our business. If we fail to integrate our platform with new third-party applications and platforms that our customers use for marketing, sales or services purposes, we may not be able to offer the functionality that our customers need, which would negatively impact our ability to generate revenue and adversely impact our business.

We rely on data provided by third parties, the loss of which could limit the functionality of our platform and disrupt our business.

Select functionality of our inbound platform depends on our ability to deliver data, including search engine results and social media updates, provided by unaffiliated third parties, such as Facebook, Google, LinkedIn and Twitter. Some of this data is provided to us pursuant to third-party data sharing policies and terms of use, under data sharing agreements by third-party providers or by customer consent. In the future, any of these third parties could change its data sharing policies, including making them more restrictive, or alter its algorithms that determine the placement, display, and accessibility of search results and social media updates, any of which could result in the loss of, or significant impairment to, our ability to collect and provide useful data to our customers. These third parties could also interpret our, or our service providers’, data collection policies or practices as being inconsistent with their policies, which could result in the loss of our ability to collect this data for our customers. Any such changes could impair our ability to deliver data to our customers and could adversely impact select functionality of our platform, impairing the return on investment that our customers derive from using our solution, as well as adversely affecting our business and our ability to generate revenue.

27

Privacy concerns and end users’ acceptance of Internet behavior tracking may limit the applicability, use and adoption of our inbound platform.

Privacy concerns may cause end users to resist providing the personal data necessary to allow our customers to use our platform effectively. We have implemented various features intended to enable our customers to better protect end user privacy, but these measures may not alleviate all potential privacy concerns and threats. Even the perception of privacy concerns, whether or not valid, may inhibit market adoption of our platform, especially in certain industries that rely on sensitive personal information. Privacy advocacy groups and the technology and other industries are considering various new, additional or different self-regulatory standards that may place additional burdens on us. The costs of compliance with, and other burdens imposed by these groups’ policies and actions may limit the use and adoption of our inbound platform and reduce overall demand for it, or lead to significant fines, penalties or liabilities for any noncompliance or loss of any such action.

We are subject to governmental regulation and other legal obligations, particularly related to privacy, data protection and information security, and our actual or perceived failure to comply with such obligations could harm our business. Compliance with such laws could also impair our efforts to maintain and expand our customer base, and thereby decrease our revenue.

Our handling of data is subject to a variety of laws and regulations, including regulation by various government agencies, including the U.S. Federal Trade Commission, or FTC, and various state, local and foreign agencies. We collect personally identifiable information and other data from our customers and leads. We also handle personally identifiable information about our customers’ customers. We use this information to provide services to our customers, to support, expand and improve our business. We may also share customers’ personally identifiable information with third parties as authorized by the customer or as described in our privacy policy.

The U.S. federal and various state and foreign governments have adopted or proposed limitations on the collection, distribution, use and storage of personal information of individuals. In the United States, the FTC and many state attorneys general are applying federal and state consumer protection laws as imposing standards for the online collection, use and dissemination of data. However, these obligations may be interpreted and applied in a manner that is inconsistent from one jurisdiction to another and may conflict with other requirements or our practices. Any failure or perceived failure by us to comply with privacy or security laws, policies, legal obligations or industry standards or any security incident that results in the unauthorized release or transfer of personally identifiable information or other customer data may result in governmental enforcement actions, litigation, fines and penalties and/or adverse publicity, and could cause our customers to lose trust in us, which could have an adverse effect on our reputation and business.

Some proposed laws or regulations concerning privacy, data protection and information security are in their early stages, and we cannot yet determine the impact these laws and regulations, if implemented, may have on our business. Such laws and regulations may require companies to implement privacy and security policies, permit users to access, correct and delete personal information stored or maintained by such companies, inform individuals of security breaches that affect their personal information, and, in some cases, obtain individuals’ consent to use personal information for certain purposes. In addition, a foreign government could require that any personal information collected in a country not be disseminated outside of that country, and we are not currently equipped to comply with such a requirement. Other proposed legislation could, if enacted, impose additional requirements and prohibit the use of certain technologies that track individuals’ activities on web pages or that record when individuals click through to an internet address contained in an email message. Such laws and regulations could require us to change features of our platform or restrict our customers’ ability to collect and use email addresses, page viewing data and personal information, which may reduce demand for our platform. Our failure to comply with federal, state and international data privacy laws and regulators could harm our ability to successfully operation our business and pursue our business goals.

28

In addition, several foreign countries and governmental bodies, including the European Union and Canada, have regulations dealing with the collection and use of personal information obtained from their residents, which are often more restrictive than those in the United States. Laws and regulations in these jurisdictions apply broadly to the collection, use, storage, disclosure and security of personal information that identifies or may be used to identify an individual, such as names, email addresses and in some jurisdictions, Internet Protocol, or IP, addresses. Such regulations and laws may be modified and new laws may be enacted in the future. Within the European Union, legislators are currently considering a revision to the 1995 European Union Data Protection Directive that would include more stringent operational requirements for processors and controllers of personal information and that would impose significant penalties for non-compliance. If our privacy or data security measures fail to comply with current or future laws and regulations, we may be subject to litigation, regulatory investigations, fines or other liabilities, as well as negative publicity and a potential loss of business. Moreover, if future laws and regulations limit our subscribers’ ability to use and share personal information or our ability to store, process and share personal information, demand for our solutions could decrease, our costs could increase, and our business, results of operations and financial condition could be harmed.

New interpretations of existing laws, regulations or standards could require us to incur additional costs and restrict our business operations, and any failure by us to comply with applicable requirements may result in governmental enforcement actions, litigation, fines and penalties or adverse publicity, which could have an adverse effect on our reputation and business.

If our or our customers’ security measures are compromised or unauthorized access to data of our customers or their customers is otherwise obtained, our inbound platform may be perceived as not being secure, our customers may be harmed and may curtail or cease their use of our platform, our reputation may be damaged and we may incur significant liabilities.

Our operations involve the storage and transmission of data of our customers and their customers, including personally identifiable information. Our storage is typically the sole source of record for portions of our customers’ businesses and end user data, such as initial contact information and online interactions. Security incidents could result in unauthorized access to, loss of or unauthorized disclosure of this information, litigation, indemnity obligations and other possible liabilities, as well as negative publicity, which could damage our reputation, impair our sales and harm our customers and our business. Cyber-attacks and other malicious Internet-based activity continue to increase generally, and cloud-based platform providers of marketing services have been targeted. If our security measures are compromised as a result of third-party action, employee or customer error, malfeasance, stolen or fraudulently obtained log-in credentials or otherwise, our reputation could be damaged, our business may be harmed and we could incur significant liability. If third parties with whom we work, such as vendors or developers, violate applicable laws or our security policies, such violations may also put our customers’ information at risk and could in turn have an adverse effect on our business. In addition, if the security measures of our customers are compromised, even without any actual compromise of our own systems, we may face negative publicity or reputational harm if our customers or anyone else incorrectly attributes the blame for such security breaches to us or our systems. We may be unable to anticipate or prevent techniques used to obtain unauthorized access or to sabotage systems because they change frequently and generally are not detected until after an incident has occurred. As we increase our customer base and our brand becomes more widely known and recognized, we may become more of a target for third parties seeking to compromise our security systems or gain unauthorized access to our customers’ data. Additionally, we provide extensive access to our database, which stores our customer data, to our development team to facilitate our rapid pace of product development. If such access or our own operations cause the loss, damage or destruction of our customers’ business data, their sales, lead generation, support and other business operations may be permanently harmed. As a result, our customers may bring claims against us for lost profits and other damages.

Many governments have enacted laws requiring companies to notify individuals of data security incidents or unauthorized transfers involving certain types of personal data. In addition, some of our customers contractually require notification of any data security compromise. Security compromises experienced by our competitors, by

29

our customers or by us may lead to public disclosures, which may lead to widespread negative publicity. Any security compromise in our industry or our systems, whether actual or perceived, could harm our reputation, erode customer confidence in the effectiveness of our security measures, negatively impact our ability to attract new customers, cause existing customers to elect not to renew their subscriptions or subject us to third-party lawsuits, lead to government investigations, regulatory fines or other action or liability, which could materially and adversely affect our business and operating results.

There can be no assurance that any limitations of liability provisions in our contracts for a security breach would be enforceable or adequate or would otherwise protect us from any such liabilities or damages with respect to any particular claim. We also cannot be sure that our existing general liability insurance coverage and coverage for errors or omissions will continue to be available on acceptable terms or will be available in sufficient amounts to cover one or more large claims, or that the insurer will not deny coverage as to any future claim. The successful assertion of one or more large claims against us that exceed available insurance coverage, or the occurrence of changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, could have a material adverse effect on our business, financial condition and operating results.

If our inbound platform fails due to defects or similar problems, and if we fail to correct any defect or other software problems, we could lose customers, become subject to service performance or warranty claims or incur significant costs.

Our platform and its underlying infrastructure are inherently complex and may contain material defects or errors. We release modifications, updates, bug fixes and other changes to our software several times per day, without traditional human-performed quality control reviews for each release. We have from time to time found defects in our software and may discover additional defects in the future. We may not be able to detect and correct defects or errors before customers begin to use our platform or its applications. Consequently, we or our customers may discover defects or errors after our platform has been implemented. These defects or errors could also cause inaccuracies in the data we collect and process for our customers, or even the loss, damage or inadvertent release of such confidential data. We implement bug fixes and upgrades as part of our regular system maintenance, which may lead to system downtime. Even if we are able to implement the bug fixes and upgrades in a timely manner, any history of defects or inaccuracies in the data we collect for our customers, or the loss, damage or inadvertent release of confidential data could cause our reputation to be harmed, and customers may elect not to purchase or renew their agreements with us and subject us to service performance credits, warranty claims or increased insurance costs. The costs associated with any material defects or errors in our platform or other performance problems may be substantial and could materially adversely affect our operating results.

Risks Related to Intellectual Property

Our business may suffer if it is alleged or determined that our technology infringes the intellectual property rights of others.

The software industry is characterized by the existence of a large number of patents, copyrights, trademarks, trade secrets and other intellectual and proprietary rights. Companies in the software industry, including those in marketing software, are often required to defend against litigation claims based on allegations of infringement or other violations of intellectual property rights. Many of our competitors and other industry participants have been issued patents and/or have filed patent applications and may assert patent or other intellectual property rights within the industry. Moreover, in recent years, individuals and groups that are non-practicing entities, commonly referred to as “patent trolls,” have purchased patents and other intellectual property assets for the purpose of making claims of infringement in order to extract settlements. From time to time, we may receive threatening letters or notices or may be the subject of claims that our services and/or platform and underlying technology infringe or violate the intellectual property rights of others. For example, as described further under “Item 3—Legal Proceedings,” on September 23, 2014, InsideSales.com, Inc. sent us a communication alleging, among other things, that an email tracking feature in our Sidekick product infringes upon certain of InsideSales.com’s

patents. Responding to the InsideSales.com claim or other such claims, regardless of their merit, can be time consuming, costly to defend in litigation, divert management’s attention and resources, damage our reputation and brand and cause us to incur significant expenses. Our technologies may not be able to withstand any third-party claims or rights against their use. Claims of intellectual property infringement might require us to redesign our application, delay releases, enter into costly settlement or license agreements or pay costly damage awards, or face a temporary or permanent injunction prohibiting us from marketing or selling our platform. If we cannot or do not license the infringed technology on reasonable terms or at all, or substitute similar technology from another source, our revenue and operating results could be adversely impacted. Additionally, our customers may not purchase our inbound platform if they are concerned that they may infringe third-party intellectual property rights. The occurrence of any of these events may have a material adverse effect on our business.

In our subscription agreements with our customers, we generally do not agree to indemnify our customers against any losses or costs incurred in connection with claims by a third party alleging that a customer’s use of our services or platform infringes the intellectual property rights of the third party. There can be no assurance, however, that customers will not assert a common law indemnity claim or that any existing limitations of liability provisions in our contracts would be enforceable or adequate, or would otherwise protect us from any such liabilities or damages with respect to any particular claim. Our customers who are accused of intellectual property infringement may in the future seek indemnification from us under common law or other legal theories. If such claims are successful, or if we are required to indemnify or defend our customers from these or other claims, these matters could be disruptive to our business and management and have a material adverse effect on our business, operating results and financial condition.

If we fail to adequately protect our proprietary rights, in the United States and abroad, our competitive position could be impaired and we may lose valuable assets, experience reduced revenue and incur costly litigation to protect our rights.

Our success is dependent, in part, upon protecting our proprietary technology. We rely on a combination of copyrights, trademarks, service marks, trade secret laws and contractual restrictions to establish and protect our proprietary rights in our products and services. However, the steps we take to protect our intellectual property may be inadequate. We will not be able to protect our intellectual property if we are unable to enforce our rights or if we do not detect unauthorized use of our intellectual property. Any of our trademarks or other intellectual property rights may be challenged by others or invalidated through administrative process or litigation. Furthermore, legal standards relating to the validity, enforceability and scope of protection of intellectual property rights are uncertain. Despite our precautions, it may be possible for unauthorized third parties to copy our technology and use information that we regard as proprietary to create products and services that compete with ours. Some license provisions protecting against unauthorized use, copying, transfer and disclosure of our offerings may be unenforceable under the laws of certain jurisdictions and foreign countries. In addition, the laws of some countries do not protect proprietary rights to the same extent as the laws of the United States. To the extent we expand our international activities, our exposure to unauthorized copying and use of our technology and proprietary information may increase.

We enter into confidentiality and invention assignment agreements with our employees and consultants and enter into confidentiality agreements with the parties with whom we have strategic relationships and business alliances. No assurance can be given that these agreements will be effective in controlling access to and distribution of our products and proprietary information. Further, these agreements may not prevent our competitors from independently developing technologies that are substantially equivalent or superior to our platform and offerings.

We may be required to spend significant resources to monitor and protect our intellectual property rights. Litigation may be necessary in the future to enforce our intellectual property rights and to protect our trade secrets. Such litigation could be costly, time consuming and distracting to management and could result in the impairment or loss of portions of our intellectual property. Furthermore, our efforts to enforce our intellectual

31

property rights may be met with defenses, counterclaims and countersuits attacking the validity and enforceability of our intellectual property rights. Our inability to protect our proprietary technology against unauthorized copying or use, as well as any costly litigation, could delay further sales or the implementation of our platform and offerings, impair the functionality of our platform and offerings, delay introductions of new features or enhancements, result in our substituting inferior or more costly technologies into our platform and offerings, or injure our reputation.

Our use of “open source” software could negatively affect our ability to offer our platform and subject us to possible litigation.

A substantial portion of our cloud-based platform incorporates so-called “open source” software, and we may incorporate additional open source software in the future. Open source software is generally freely accessible, usable and modifiable. Certain open source licenses may, in certain circumstances, require us to offer the components of our platform that incorporate the open source software for no cost, that we make available source code for modifications or derivative works we create based upon, incorporating or using the open source software and that we license such modifications or derivative works under the terms of the particular open source license. If an author or other third party that distributes open source software we use were to allege that we had not complied with the conditions of one or more of these licenses, we could be required to incur significant legal expenses defending against such allegations and could be subject to significant damages, including being enjoined from the offering of the components of our platform that contained the open source software and being required to comply with the foregoing conditions, which could disrupt our ability to offer the affected software. We could also be subject to suits by parties claiming ownership of what we believe to be open source software. Litigation could be costly for us to defend, have a negative effect on our operating results and financial condition and require us to devote additional research and development resources to change our products.

Risks Related to Government Regulation and Taxation

We could face liability, or our reputation might be harmed, as a result of the activities of our customers, the content of their websites or the data they store on our servers.

As a provider of a cloud-based inbound marketing and sales software platform, we may be subject to potential liability for the activities of our customers on or in connection with the data they store on our servers. Although our customer terms of use prohibit illegal use of our services by our customers and permit us to take down websites or take other appropriate actions for illegal use, customers may nonetheless engage in prohibited activities or upload or store content with us in violation of applicable law or the customer’s own policies, which could subject us to liability or harm our reputation.

Several U.S. federal statutes may apply to us with respect to various customer activities:

• The Digital Millennium Copyright Act of 1998, or DMCA, provides recourse for owners of copyrighted material who believe that their rights under U.S. copyright law have been infringed on the Internet. Under the DMCA, based on our current business activity as an Internet service provider that does not own or control website content posted by our customers, we generally are not liable for infringing content posted by our customers or other third parties, provided that we follow the procedures for handling copyright infringement claims set forth in the DMCA. Generally, if we receive a proper notice from, or on behalf, of a copyright owner alleging infringement of copyrighted material located on websites we host, and we fail to expeditiously remove or disable access to the allegedly infringing material or otherwise fail to meet the requirements of the safe harbor provided by the DMCA, the copyright owner may seek to impose liability on us. Technical mistakes in complying with the detailed DMCA take-down procedures could subject us to liability for copyright infringement.

• The Communications Decency Act of 1996, or CDA, generally protects online service providers, such as us, from liability for certain activities of their customers, such as the posting of defamatory or

32

obscene content, unless the online service provider is participating in the unlawful conduct. Under the CDA, we are generally not responsible for the customer-created content hosted on our servers. Consequently, we do not monitor hosted websites or prescreen the content placed by our customers on their sites. However, the CDA does not apply in foreign jurisdictions and we may nonetheless be brought into disputes between our customers and third parties which would require us to devote management time and resources to resolve such matters and any publicity from such matters could also have an adverse effect on our reputation and therefore our business.

• In addition to the CDA, the Securing the Protection of our Enduring and Established Constitutional Heritage Act, or the SPEECH Act, provides a statutory exception to the enforcement by a U.S. court of a foreign judgment for defamation under certain circumstances. Generally, the exception applies if the defamation law applied in the foreign court did not provide at least as much protection for freedom of speech and press as would be provided by the First Amendment of the U.S. Constitution or by the constitution and law of the state in which the U.S. court is located, or if no finding of defamation would be supported under the First Amendment of the U.S. Constitution or under the constitution and law of the state in which the U.S. court is located. Although the SPEECH Act may protect us from the enforcement of foreign judgments in the United States, it does not affect the enforceability of the judgment in the foreign country that issued the judgment. Given our international presence, we may therefore, nonetheless, have to defend against or comply with any foreign judgments made against us, which could take up substantial management time and resources and damage our reputation.

Although these statutes and case law in the United States have generally shielded us from liability for customer activities to date, court rulings in pending or future litigation may narrow the scope of protection afforded us under these laws. In addition, laws governing these activities are unsettled in many international jurisdictions, or may prove difficult or impossible for us to comply with in some international jurisdictions. Also, notwithstanding the exculpatory language of these bodies of law, we may become involved in complaints and lawsuits which, even if ultimately resolved in our favor, add cost to our doing business and may divert management’s time and attention. Finally, other existing bodies of law, including the criminal laws of various states, may be deemed to apply or new statutes or regulations may be adopted in the future, any of which could expose us to further liability and increase our costs of doing business.

We may be subject to additional obligations to collect and remit sales tax and other taxes, and we may be subject to tax liability for past sales, which could harm our business.

State, local and foreign jurisdictions have differing rules and regulations governing sales, use, value added and other taxes, and these rules and regulations are subject to varying interpretations that may change over time. In particular, the applicability of such taxes to our inbound platform in various jurisdictions is unclear. Further, these jurisdictions’ rules regarding tax nexus are complex and vary significantly. As a result, we could face the possibility of tax assessments and audits, and our liability for these taxes and associated penalties could exceed our original estimates. A successful assertion that we should be collecting additional sales, use, value added or other taxes in those jurisdictions where we have not historically done so and do not accrue for such taxes could result in substantial tax liabilities and related penalties for past sales, discourage customers from purchasing our application or otherwise harm our business and operating results.

Changes in tax laws or regulations that are applied adversely to us or our customers could increase the costs of our inbound platform and adversely impact our business.

New income, sales, use or other tax laws, statutes, rules, regulations or ordinances could be enacted at any time. Any new taxes could adversely affect our domestic and international business operations, and our business and financial performance. Further, existing tax laws, statutes, rules, regulations or ordinances could be interpreted, changed, modified or applied adversely to us. These events could require us or our customers to pay additional tax amounts on a prospective or retroactive basis, as well as require us or our customers to pay fines

33

and/or penalties and interest for past amounts deemed to be due. If we raise our prices to offset the costs of these changes, existing and potential future customers may elect not to continue or purchase our inbound platform in the future. Additionally, new, changed, modified or newly interpreted or applied tax laws could increase our customers’ and our compliance, operating and other costs, as well as the costs of our platform. Any or all of these events could adversely impact our business and financial performance.

We are a multinational organization faced with increasingly complex tax issues in many jurisdictions, and we could be obligated to pay additional taxes in various jurisdictions.

As a multinational organization, we may be subject to taxation in several jurisdictions around the world with increasingly complex tax laws, the application of which can be uncertain. The amount of taxes we pay in these jurisdictions could increase substantially as a result of changes in the applicable tax principles, including increased tax rates, new tax laws or revised interpretations of existing tax laws and precedents, which could have a material adverse effect on our liquidity and operating results. In addition, the authorities in these jurisdictions could review our tax returns and impose additional tax, interest and penalties, and the authorities could claim that various withholding requirements apply to us or our subsidiaries or assert that benefits of tax treaties are not available to us or our subsidiaries, any of which could have a material impact on us and the results of our operations.

Failure to comply with laws and regulations could harm our business.

Our business is subject to regulation by various federal, state, local and foreign governmental agencies, including agencies responsible for monitoring and enforcing employment and labor laws, workplace safety, environmental laws, consumer protection laws, anti-bribery laws, import/export controls, federal securities laws and tax laws and regulations. In certain jurisdictions, these regulatory requirements may be more stringent than those in the United States. Noncompliance with applicable regulations or requirements could subject us to investigations, sanctions, mandatory recalls, enforcement actions, disgorgement of profits, fines, damages, civil and criminal penalties or injunctions.

We may not be able to utilize a significant portion of our net operating loss carryforwards, which could adversely affect our profitability.

As of December 31, 2014, we had federal and state net operating loss carryforwards due to prior period losses, which, if not utilized, will begin to expire in 2027 for federal purposes and 2014 for state purposes. These net operating loss carryforwards could expire unused and be unavailable to offset future income tax liabilities, which could adversely affect our profitability. In addition, under Section 382 of the Internal Revenue Code of 1986, as amended, which we refer to as the Code, our ability to utilize net operating loss carryforwards or other tax attributes, such as research tax credits, in any taxable year may be further limited if we experience an ownership change. A Section 382 ownership change generally occurs if one or more stockholders or groups of stockholders who own at least 5% of our stock increase their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. Similar rules may apply under state tax laws. future issuances of our stock could cause an ownership change. It is possible that an ownership change in connection with a future offering, or any future ownership change, could have a material effect on the use of our net operating loss carryforwards or other tax attributes, which could adversely affect our profitability.

The standards that private entities use to regulate the use of email have in the past interfered with, and may in the future interfere with, the effectiveness of our inbound platform and our ability to conduct business.

Our customers rely on email to communicate with their existing or prospective customers. Various private entities attempt to regulate the use of email for commercial solicitation. These entities often advocate standards of conduct or practice that significantly exceed current legal requirements and classify certain email solicitations that comply with current legal requirements as spam. Some of these entities maintain “blacklists” of companies

34

and individuals, and the websites, internet service providers and internet protocol addresses associated with those entities or individuals that do not adhere to those standards of conduct or practices for commercial email solicitations that the blacklisting entity believes are appropriate. If a company’s internet protocol addresses are listed by a blacklisting entity, emails sent from those addresses may be blocked if they are sent to any internet domain or internet address that subscribes to the blacklisting entity’s service or purchases its blacklist.

From time to time, some of our internet protocol addresses may become listed with one or more blacklisting entities due to the messaging practices of our customers. There can be no guarantee that we will be able to successfully remove ourselves from those lists. Blacklisting of this type could interfere with our ability to market our inbound platform and services and communicate with our customers and, because we fulfill email delivery on behalf of our customers, could undermine the effectiveness of our customers’ email marketing campaigns, all of which could have a material negative impact on our business and results of operations.

Existing federal, state and foreign laws regulate Internet tracking software, the senders of commercial emails and text messages, website owners and other activities, and could impact the use of our inbound platform and potentially subject us to regulatory enforcement or private litigation.

Certain aspects of how our customers utilize our platform are subject to regulations in the United States, European Union and elsewhere. In recent years, U.S. and European lawmakers and regulators have expressed concern over the use of third-party cookies or web beacons for online behavioral advertising, and legislation adopted recently in the European Union requires informed consent for the placement of a cookie on a user’s device. Regulation of cookies and web beacons may lead to restrictions on our activities, such as efforts to understand users’ Internet usage. New and expanding “Do Not Track” regulations have recently been enacted or proposed that protect users’ right to choose whether or not to be tracked online. These regulations seek, among other things, to allow end users to have greater control over the use of private information collected online, to forbid the collection or use of online information, to demand a business to comply with their choice to opt out of such collection or use, and to place limits upon the disclosure of information to third party websites. These policies could have a significant impact on the operation of our inbound platform and could impair our attractiveness to customers, which would harm our business.

Many of our customers and potential customers in the healthcare, financial services and other industries are subject to substantial regulation regarding their collection, use and protection of data and may be the subject of further regulation in the future. Accordingly, these laws or significant new laws or regulations or changes in, or repeals of, existing laws, regulations or governmental policy may change the way these customers do business and may require us to implement additional features or offer additional contractual terms to satisfy customer and regulatory requirements, or could cause the demand for and sales of our inbound platform to decrease and adversely impact our financial results.

In addition, the Controlling the Assault of Non-Solicited Pornography and Marketing Act of 2003, or the CAN-SPAM Act, establishes certain requirements for commercial email messages and specifies penalties for the transmission of commercial email messages that are intended to deceive the recipient as to source or content. The CAN-SPAM Act, among other things, obligates the sender of commercial emails to provide recipients with the ability to opt out of receiving future commercial emails from the sender. The ability of our customers’ message recipients to opt out of receiving commercial emails may minimize the effectiveness of the email components of our inbound platform. In addition, certain states and foreign jurisdictions, such as Australia, Canada and the European Union, have enacted laws that regulate sending email, and some of these laws are more restrictive than U.S. laws. For example, some foreign laws prohibit sending unsolicited email unless the recipient has provided the sender advance consent to receipt of such email, or in other words has “opted-in” to receiving it. A requirement that recipients opt into, or the ability of recipients to opt out of, receiving commercial emails may minimize the effectiveness of our platform.

While these laws and regulations generally govern our customers’ use of our platform, we may be subject to certain laws as a data processor on behalf of, or as a business associate of, our customers. For example, laws and

35

regulations governing the collection, use and disclosure of personal information include, in the United States, rules and regulations promulgated under the authority of the Federal Trade Commission, the Health Insurance Portability and Accountability Act of 1996, the Gramm-Leach-Bliley Act of 1999 and state breach notification laws, and internationally, the Data Protection Directive in the European Union and the Federal Data Protection Act in Germany. If we were found to be in violation of any of these laws or regulations as a result of government enforcement or private litigation, we could be subjected to civil and criminal sanctions, including both monetary fines and injunctive action that could force us to change our business practices, all of which could adversely affect our financial performance and significantly harm our reputation and our business.

We are subject to governmental export controls and economic sanctions laws that could impair our ability to compete in international markets and subject us to liability if we are not in full compliance with applicable laws.

Our business activities are subject to various restrictions under U.S. export controls and trade and economic sanctions laws, including the U.S. Commerce Department’s Export Administration Regulations and economic and trade sanctions regulations maintained by the U.S. Treasury Department’s Office of Foreign Assets Control. If we fail to comply with these laws and regulations, we and certain of our employees could be subject to civil or criminal penalties and reputational harm. Obtaining the necessary authorizations, including any required license, for a particular transaction may be time-consuming, is not guaranteed, and may result in the delay or loss of sales opportunities. Furthermore, U.S. export control laws and economic sanctions laws prohibit certain transactions with U.S. embargoed or sanctioned countries, governments, persons and entities. Although we take precautions to prevent transactions with U.S. sanction targets, the possibility exists that we could inadvertently provide our solutions to persons prohibited by U.S. sanctions. This could result in negative consequences to us, including government investigations, penalties and reputational harm.

Risks Related to Our Operating Results and Financial Condition

We may experience quarterly fluctuations in our operating results due to a number of factors, which makes our future results difficult to predict and could cause our operating results to fall below expectations or our guidance.

Our quarterly operating results have fluctuated in the past and are expected to fluctuate in the future due to a variety of factors, many of which are outside of our control. As a result, our past results may not be indicative of our future performance, and comparing our operating results on a period-to-period basis may not be meaningful. In addition to the other risks described in this Annual Report on Form 10-K, factors that may affect our quarterly operating results include the following:

• changes in spending on marketing and sales software by our current or prospective customers;

• pricing our inbound platform subscriptions effectively so that we are able to attract and retain customers without compromising our profitability;

• attracting new customers for both our marketing and sales software, increasing our existing customers’ use of our platform and providing our customers with excellent customer support;

• customer renewal rates and the amounts for which agreements are renewed;

• global awareness of our thought leadership and brand;

• changes in the competitive dynamics of our market, including consolidation among competitors or customers and the introduction of new products or product enhancements;

• changes to the commission plans, quotas and other compensation-related metrics for our sales representatives;

• the amount and timing of payment for operating expenses, particularly research and development, sales and marketing expenses and employee benefit expenses;

36

• the amount and timing of costs associated with recruiting, training and integrating new employees while maintaining our company culture;

• our ability to manage our existing business and future growth, including increases in the number of customers on our platform and the introduction and adoption of our inbound platform in new markets outside of the United States;

• unforeseen costs and expenses related to the expansion of our business, operations and infrastructure, including disruptions in our hosting network infrastructure and privacy and data security;

• foreign currency exchange rate fluctuations; and

• general economic and political conditions in our domestic and international markets.

We may not be able to accurately forecast the amount and mix of future subscriptions, revenue and expenses and, as a result, our operating results may fall below our estimates or the expectations of public market analysts and investors. If our revenue or operating results fall below the expectations of investors or securities analysts, or below any guidance we may provide, the price of our common stock could decline.

If we do not accurately predict subscription renewal rates or otherwise fail to forecast our revenue accurately, or if we fail to match our expenditures with corresponding revenue, our operating results could be adversely affected.

Because our recent growth has resulted in the rapid expansion of our business, we do not have a long history upon which to base forecasts of renewal rates with customers or future operating revenue. As a result, our operating results in future reporting periods may be significantly below the expectations of the public market, equity research analysts or investors, which could harm the price of our common stock.

Because we generally recognize revenue from subscriptions ratably over the term of the agreement, near term changes in sales may not be reflected immediately in our operating results.

We offer our inbound platform primarily through a mix of monthly, quarterly and single-year subscription agreements and generally recognize revenue ratably over the related subscription period. As a result, much of the revenue we report in each quarter is derived from agreements entered into during prior months, quarters or years. In addition, we do not record deferred revenue beyond amounts invoiced as a liability on our balance sheet. A decline in new or renewed subscriptions or marketing solutions agreements in any one quarter is not likely to be reflected immediately in our revenue results for that quarter. Such declines, however, would negatively affect our revenue and deferred revenue balances in future periods, and the effect of significant downturns in sales and market acceptance of our platform, and potential changes in our rate of renewals, may not be fully reflected in our results of operations until future periods. Our subscription model also makes it difficult for us to rapidly increase our total revenue and deferred revenue balance through additional sales in any period, as revenue from new customers must be recognized over the applicable subscription term.

We are exposed to fluctuations in currency exchange rates.

We face exposure to movements in currency exchange rates, which may cause our revenue and operating results to differ materially from expectations. Our operating results could be negatively affected depending on the amount of expense denominated in foreign currencies, primarily the Euro. As exchange rates vary, revenue, cost of revenue, operating expenses and other operating results, when re-measured, may differ materially from expectations. In addition, our operating results are subject to fluctuation if our mix of U.S. and foreign currency denominated transactions and expenses changes in the future. Although we may apply certain strategies to mitigate foreign currency risk, these strategies might not eliminate our exposure to foreign exchange rate fluctuations and would involve costs and risks of their own, such as ongoing management time and expertise, external costs to implement the strategies and potential accounting implications. Additionally, as we anticipate

37

growing our business further outside of the United States, the effects of movements in currency exchange rates will increase as our transaction volume outside of the United States increases.

Risks Related to Our Common Stock

Our stock price may be volatile and you may be unable to sell your shares at or above the price you purchased them.

The trading prices of the securities of technology companies, including providers of software via the cloud-based model, have been highly volatile. Since shares of our common stock were sold in our initial public offering in October 2014 at a price of $25.00 per share, our stock price has ranged from $44.34 to $25.79, through March 4, 2015. The market price of our common stock may fluctuate significantly in response to numerous factors, many of which are beyond our control, including:

• actual or anticipated fluctuations in our revenue and other operating results, including as a result of the addition or loss of any number of customers;

• announcements by us or our competitors of significant technical innovations, acquisitions, strategic partnerships, joint ventures or capital commitments;

• the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections;

• failure of securities analysts to initiate or maintain coverage of us, changes in ratings and financial estimates and the publication of other news by any securities analysts who follow our company, or our failure to meet these estimates or the expectations of investors;

• changes in operating performance and stock market valuations of cloud-based software or other technology companies, or those in our industry in particular;

• price and volume fluctuations in the trading of our common stock and in the overall stock market, including as a result of trends in the economy as a whole;

• new laws or regulations or new interpretations of existing laws or regulations applicable to our business or industry, including data privacy and data security;

• lawsuits threatened or filed against us;

• changes in key personnel; and

• other events or factors, including changes in general economic, industry and market conditions and trends.

In addition, the stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many technology companies. Stock prices of many technology companies have fluctuated in a manner unrelated or disproportionate to the operating performance of those companies.

In the past, stockholders have instituted securities class action litigation following periods of market volatility. If we were to become involved in securities litigation, it could subject us to substantial costs, divert resources and the attention of management from our business and adversely affect our business.

The concentration of our capital stock ownership with insiders will likely limit your ability to influence corporate matters including the ability to influence the outcome of director elections and other matters requiring stockholder approval.

Executive officers, directors, current five percent or greater stockholders and affiliated entities together beneficially own 52.8% of our common stock outstanding. As a result, these stockholders, acting together,

38

continue to have significant influence over all matters that require approval by our stockholders, including the election of directors and approval of significant corporate transactions. Corporate action might be taken even if other stockholders oppose them. This concentration of ownership might also have the effect of delaying or preventing a change of control of our company that other stockholders may view as beneficial.

We are an “emerging growth company” and the reduced disclosure requirements applicable to emerging growth companies may make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in the JOBS Act, and we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced financial disclosure obligations, 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 any golden parachute payments not previously approved. As an “emerging growth company” under the JOBS Act, we are permitted to delay the adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. However, we have elected not to take advantage of such extended transition period, and as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. Section 107 of the JOBS Act provides that our decision to not take advantage of the extended transition period for complying with new or revised accounting standards is irrevocable.

We may take advantage of these provisions until we are no longer an “emerging growth company”. We would cease to be an “emerging growth company” upon the earliest to occur of: the last day of the fiscal year in which we have more than $1.0 billion in annual revenue; the date we qualify as a “large accelerated filer,” with at least $700 million of equity securities held by non-affiliates; the issuance, in any three-year period, by us of more than $1.0 billion in non-convertible debt securities; and the last day of the fiscal year ending after the fifth anniversary of our initial public offering. If we take advantage of any of these reduced reporting burdens in future filings, the information that we provide our security holders may be different than you might get from other public companies in which you hold equity interests. We cannot predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

We will continue to incur increased costs and demands upon management as a result of complying with the laws and regulations affecting public companies, particularly after we are no longer an “emerging growth company,” which could adversely affect our business, operating results and financial condition.

As a public company, and particularly after we cease to be an “emerging growth company,” we will continue to incur significant legal, accounting and other expenses. We are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act, the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, and the rules and regulations of the New York Stock Exchange, or NYSE. These requirements 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 incur substantially higher costs to maintain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified individuals to serve on our board of directors or as our executive officers.

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

39

quarterly. In particular, beginning in 2015, Section 404 of the Sarbanes-Oxley Act, or Section 404, will require us 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. We have identified certain internal control deficiencies surrounding our systems and closing process. We have and will continue to remediate these deficiencies by investing in our financial systems and adding additional personnel, including outside consultants. As an emerging growth company, we are availing 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. However, we may no longer avail ourselves of this exemption when we cease to be an emerging growth company. 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 requirements effectively or efficiently, it could harm our operations, financial reporting, or financial results and could result in an adverse opinion on our internal controls from our independent registered public accounting firm.

After we are no longer an emerging growth company, or sooner if we choose not to take advantage of certain exemptions set forth in the JOBS Act, we expect to incur significant expenses and devote substantial management effort toward ensuring compliance with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act. In that regard, we will need to hire additional accounting and financial staff with appropriate public company experience and technical accounting knowledge.

Our ability to raise capital in the future may be limited, and our failure to raise capital when needed could prevent us from growing.

Our business and operations may consume resources faster than we anticipate. In the future, we may need to raise additional funds to invest in future growth opportunities. Additional financing may not be available on favorable terms, if at all. If adequate funds are not available on acceptable terms, we may be unable to invest in future growth opportunities, which could seriously harm our business and operating results. If we incur debt, the debt holders would have rights senior to common stockholders to make claims on our assets, and the terms of any debt could restrict our operations, including our ability to pay dividends on our common stock. Furthermore, if we issue additional equity securities, stockholders will experience dilution, and the new equity securities could have rights senior to those of our common stock. Because our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. As a result, our stockholders bear the risk of our future securities offerings reducing the market price of our common stock and diluting their interest.

40

A significant portion of our total outstanding shares are restricted from immediate resale but may be sold into the market in the near future. This could cause the market price of our common stock to drop significantly, even if our business is doing well.

Sales of a substantial number of shares of our common stock in the public market could occur at any time after the expiration or waiver of the lock-up agreements. If our stockholders sell, or the market perceives that our stockholders intend to sell, substantial amounts of our common stock in the public market, the market price of our common stock could decline significantly.

As of December 31, 2014, we have outstanding 31,430,769 shares of common stock. Of these shares, 5,750,000 shares are immediately freely tradable, and approximately 25,680,769 additional shares of common stock will be available for sale in the public market beginning on April 8, 2015 following the expiration of lock-up agreements. The representatives of the underwriters may release these stockholders from their lock-up agreements with the underwriters at any time and without notice, which would allow for earlier sales of shares in the public market.

As of December 31, 2014, an aggregate of 1,857,327 shares of our common stock are reserved for future issuance under our 2014 Plan, and 394,710 shares of our common stock are reserved for future issuance under our ESPP. Shares registered under our registration statements on Form S-8, including the shares reserved for future issuance under our 2014 Plan and ESPP as described in the previous sentence, are available for sale in the public market subject to vesting arrangements and exercise of options, the lock-up agreements described above and the restrictions of Securities Act Rule 144 in the case of our affiliates.

Additionally, the holders of an aggregate of 20,200,445 shares of our common stock have rights, subject to some conditions, to require us to file one or more registration statements covering their shares or to include their shares in registration statements that we may file for ourselves or other stockholders. If we were to register these shares for resale, they could be freely sold in the public market. If these additional shares are sold, or if it is perceived that they will be sold, in the public market, the trading price of our common stock could decline.

Anti-takeover provisions in our charter documents and Delaware law may delay or prevent an acquisition of our company.

Our amended and restated certificate of incorporation, amended and restated bylaws and Delaware law contain provisions that may have the effect of delaying or preventing a change in control of us or changes in our management. Our amended and restated certificate of incorporation and bylaws include provisions that:

• authorize “blank check” preferred stock, which could be issued by the board without stockholder approval and may contain voting, liquidation, dividend and other rights superior to our common stock;

• provide for a classified board of directors whose members serve staggered three-year terms;

• specify that special meetings of our stockholders can be called only by our board of directors, the chairperson of the board, the chief executive officer or the president;

• prohibit stockholder action by written consent;

• establish an advance notice procedure for stockholder approvals to be brought before an annual meeting of our stockholders, including proposed nominations of persons for election to our board of directors;

• provide that our directors may be removed only for cause;

• provide that vacancies on our board of directors may be filled only by a majority of directors then in office, even though less than a quorum;

• specify that no stockholder is permitted to cumulate votes at any election of directors;

41

• authorize our board of directors to modify, alter or repeal our amended and restated bylaws; and

• require supermajority votes of the holders of our common stock to amend specified provisions of our charter documents.

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

In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which limits the ability of stockholders owning in excess of 15% of our outstanding voting stock to merge or combine with us in certain circumstances.

Any provision of our amended and restated certificate of incorporation or amended and restated 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.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 2. Properties

We occupy approximately 100,000 square feet of office space in Cambridge, Massachusetts pursuant to a lease agreement that expires in 2020. We also maintain an office in Dublin, Ireland and Sydney, Australia. We believe that our current facilities are suitable and adequate to meet our current needs. We intend to add new facilities or expand existing facilities as we add employees, and we believe that suitable additional or substitute space will be available as needed to accommodate any such expansion of our operations.

ITEM 3. Legal Proceedings

On November 13, 2013, a putative class action complaint was filed in the Middlesex County Superior Court in the Commonwealth of Massachusetts, entitled Albert McCormack v. HubSpot, Inc. The complaint alleged that we maintained a policy of not paying overtime to our business development representatives for all hours worked in excess of 40 hours per week. The complaint sought unpaid wages, multiple damages, injunctive relief, attorneys’ fees and costs. We settled this matter for an immaterial amount and the complaint was dismissed on November 3, 2014.

On September 23, 2014, InsideSales.com, Inc. sent us a communication alleging, among other things, that an email tracking feature in our Sidekick product infringes upon certain of InsideSales.com’s patents. We are continuing to evaluate InsideSales.com’s claims, but based on the information available to us today, we currently believe that this threat and any potential litigation will not have a material adverse effect on our business or our consolidated financial statements.

In addition, from time to time we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. Although the results of litigation and claims cannot be predicted with certainty, we currently believe that the final outcome of these ordinary course matters will not have a material adverse effect on our business, operating results, financial condition or cash flows. 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.

ITEM 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Market Information for Common Stock

Our common stock has been listed on the New York Stock Exchange under the symbol “HUBS” since October 9, 2014. Prior to that date, there was no public trading market for our common stock. Our initial public offering was priced at $25.00 per share on October 8, 2014. The following table sets forth for the periods indicated the high and low sales prices per share of our common stock as reported on the New York Stock Exchange:

	High		Low
Fourth Quarter (from October 9, 2014 to December 31, 2014)	$	38.60	$	25.79
First Quarter (from January 1, 2015 to March 4, 2015)	$	44.34	$	31.77

On March 4, 2015, the last reported sale price of our common stock on the New York Stock Exchange was $44.34 per share. As of December 31, 2014, we had 455 holders of record of our common stock. The actual number of shareholders is greater than this number of record holders, and includes shareholders who are beneficial owners, but whose shares are held in street name by brokers and other nominees. This number of holders of record also does not include shareholders whose shares may be held in trust by other entities.

Dividends

We have never declared or paid any cash dividends on our common stock. We currently anticipate that we will retain future earnings to fund development and growth of our business and to repurchase our common stock, and do not anticipate paying cash dividends in the foreseeable future.

Use of Proceeds from Public Offering of Common Stock

On October 15, 2014 the Company closed its IPO whereby 5,750,000 shares of common stock were sold to the public, including the underwriters’ overallotment option of 750,000 shares of common stock, at a price of $25.00 per share. The Company received aggregate proceeds of approximately $133.7 million from the IPO, net of underwriters’ discounts and commissions, but before deduction of offering expenses of approximately $3.1 million. Upon the closing of the IPO, all shares of the Company’s outstanding convertible preferred stock automatically converted into 19,529,713 shares of common stock. The Company used $18 million of the IPO proceeds to pay down its then outstanding line of credit balance.

We invested the funds received in registered money market funds.

Purchases of Equity Securities by the Issuer and Affiliated Purchasers

ITEM 7. 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 our consolidated financial statements and related notes that appear elsewhere in this Annual Report on Form 10-K. As discussed in the section titled “Special Note Regarding Forward-Looking Statements,” the following discussion and analysis contains forward-looking statements that involve risks and uncertainties, as well as assumptions that, if they never materialize or prove incorrect, could cause our results to differ materially from those expressed or implied by such forward-looking statements. 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 under Part I, Item 1A within this Annual Report on Form 10-K.

Company Overview

We provide a cloud-based marketing and sales software platform that enables businesses to deliver an inbound experience. An inbound marketing and sales experience attracts, engages and delights customers by being more relevant, more helpful, more personalized and less interruptive than traditional marketing and sales tactics. Our software platform features integrated applications to help businesses attract visitors to their websites, convert visitors into leads, close leads into customers and delight customers so that they become promoters of those businesses. These integrated applications include social media, search engine optimization, blogging, website content management, marketing automation, email, CRM, analytics and reporting.

We designed our all-in-one platform from the ground up to enable businesses to provide an inbound experience to their prospects and customers. At the core of our platform is a single inbound database for each business that captures its customer activity throughout the customer lifestyle. Our platform uses our centralized inbound database to empower businesses to create more personalized interactions with customers, such as personalized emails, personalized social media alerts, personalized websites and targeted alerts for sales people. We provide a comprehensive set of integrated applications on our platform, which offers businesses ease of use, power and simplicity. We designed and built our platform to serve a large numbers of customers of any size with demanding use cases.

While our platform can scale to the enterprise, we focus on selling to mid-market businesses because we believe we have significant competitive advantages attracting and serving them. We efficiently reach these businesses at scale through our proven inbound go-to-market approach and more than 2,200 marketing agency partners worldwide. Our platform is particularly suited to serving the needs of mid-market business-to-business companies. These mid-market businesses seek an integrated, easy to implement and easy to use solution to reach customers and compete with organizations that have larger marketing and sales budgets. As of December 31, 2014, we had 13,607 customers of varying sizes in more than 90 countries, representing almost every industry.

Our platform is a multi-tenant, single code-based and globally available software-as-a-service, or SaaS, product delivered through web browsers or mobile applications. We sell our platform on a subscription basis and generated revenue of $115.9 million in 2014, $77.6 million in 2013, and $51.6 million in 2012, representing year-over-year increases of 49% in 2014 and 50% in 2013. We had net losses of $48.2 million in 2014, $34.3 million in 2013, and $18.8 million in 2012, primarily due to increased investments in our growth.

We derive most of our revenue from subscriptions to our cloud-based software platform and related professional services, which consist of customer on-boarding and training services. Subscription revenue accounted for 91.8% of our total revenue for the year ended December 31, 2014, 91.2% of our total revenue for the year ended December 31, 2013, and 88.9% of our total revenue for the year ended December 31, 2012. We sell three product plans at different base prices on a subscription basis, each of which includes our core platform and integrated applications to meet the needs of thevarious customers we serve. Customers pay additional fees if the number of contacts stored and tracked in the customer’s database exceeds specified thresholds. We generate additional revenue based on the purchase of additional subscriptions and applications and the number of account users, subdomains and website visits. Substantially all of our customers’ subscriptions are one year or less in duration.

48

Subscriptions are non-cancelable and are billed in advance on various schedules. Because the mix of billing terms for orders can vary from period to period, the annualized value of the orders we enter into with our customers will not be completely reflected in deferred revenue at any single point in time. Accordingly, we do not believe that change in deferred revenue is an accurate indicator of future revenue for a given period of time.

Professional services and other revenue accounted for 8.2% of our total revenue in 2014, 8.8% in 2013, and 11.1% in 2012. Most of our customers purchase training services which are designed to help customers enhance their ability to attract, engage and delight their customers using our platform.

Our customer base has grown from 10,111 customers at the end of 2013 to 13,607 customers as of December 31, 2014, which has resulted in rapid revenue growth. As of December 31, 2014, approximately 22% of our customers were located outside of the United States and these customers generated approximately 21% of our total revenue for the year ended December 31, 2014. We opened our first international office in Dublin, Ireland in January 2013, and our second international office in Sydney, Australia in August 2014, as part of our geographic expansion. We plan to further grow our international business and expand to other geographies.

We have focused on rapidly growing our business and plan to continue to make investments to help us address some of the challenges facing us to support this growth, such as demand for our platform by existing and new customers, significant competition from other providers of marketing software and related applications and rapid technological change in our industry. We believe that the growth of our business is dependent on many factors, including our ability to expand our customer base, increase adoption of our platform within existing customers, develop new products and applications to extend the functionality of our platform and provide a high level of customer service. We expect to increase our investment in sales and marketing as we continue to expand our sales teams, increase our marketing activities and grow our international operations. We also expect to increase our investment in research and development as we continue to introduce new products and applications to extend the functionality of our platform. We also intend to invest in maintaining a high level of customer service and support which we consider critical for our continued success. We plan to continue investing in our data center infrastructure and services capabilities in order to support continued future customer growth. We also expect to continue to incur additional general and administrative expenses as a result of both our growth and the infrastructure required to be a public company. We expect to use the proceeds from our recent initial public offering to fund these growth strategies and do not expect to be profitable in the near term.

We believe that these investments will result in an increase in our subscription revenue base and improvement in the retention of this base. This will result in revenue increasing faster than the increase in sales and marketing, research and development and general and administrative expenses. Exclusive of stock-based compensation as we reach economies of scale. With this increased operating leverage, we expect our gross and operating margins to increase in the long term. However, we will incur losses in the short term. If we are unable to achieve our revenue growth objectives, including a high rate of renewals of our customer agreements, we may not be able to achieve profitability.

Key Business Metrics

We use the following key business metrics to evaluate our business, measure our performance, identify trends affecting our business, formulate financial projections and make strategic decisions. Our key business metrics may be calculated in a manner different than similar key business metrics used by other companies.

	Year Ended December 31,
	2014			2013			2012
Total customers		13,607			10,111			8,159
Average subscription revenue per customer	$	8,926		$	7,752		$	6,580
Subscription dollar retention rate		92.7	%		82.9	%		82.4	%
Customer Acquisition Cost, or CAC	$	11,977		$	11,645		$	8,279

49

Total Customers. We believe that our ability to increase our customer base is an indicator of our market penetration and growth of our business as we continue to expand our sales force and invest in marketing efforts. We define our total customers at the end of a particular period as the number of business entities or individuals with one or more paid subscriptions to our marketing platform, either paid directly or through an agency partner. We do not include in total customers business entities or individuals with one or more paid subscriptions solely for our Sidekick product. More than 300,000 individuals with a free or paid Sidekick account used our Sidekick product during December 2014. A single customer may have separate paid subscriptions for separate websites, but we count these as one customer if the subscriptions are managed by the same business entity or individual. For more information about our customers, see the section of this Annual Report on Form 10-K captioned “Business—Our Customers.”

Average Subscription Revenue per Customer. We believe that our ability to increase the average subscription revenue per customer is an indicator of our ability to grow the long-term value of our existing customer relationships. We define average subscription revenue per customer during a particular period as subscription revenue from our total customers during the period divided by the average total customers during the same period. We expect our average subscription revenue per customer to continue to increase over time.

Subscription Dollar Retention Rate. We believe that our ability to retain and expand a customer relationship is an indicator of the stability of our revenue base and the long-term value of our customers. We assess our performance in this area using a metric we refer to as our Subscription Dollar Retention Rate. We compare the aggregate Contractual Monthly Subscription Revenue of our customer base as of the beginning of each month, which we refer to as Retention Base Revenue, to the aggregate Contractual Monthly Subscription Revenue of the same group of customers at the end of that month, which we refer to as Retained Subscription Revenue. We define Contractual Monthly Subscription Revenue as the total amount of subscription fees contractually committed to be paid for a full month under all of our customer agreements, excluding any commissions owed to our partners. We do not include in Contractual Monthly Subscription Revenue any subscription fees contractually committed to be paid by business entities or individuals with subscriptions solely for our Sidekick product. Our Subscription Dollar Retention Rate for a given period is calculated by first dividing Retained Subscription Revenue by Retention Base Revenue for each month in the period, calculating the weighted average of these rates using the Retention Base Revenue for each month in the period, and then annualizing the resulting rates.

Customer Acquisition Cost. We believe that customer acquisition cost, or CAC, is an indicator of the efficiency of our sales and marketing programs in acquiring new customers. We calculate CAC by dividing our total sales and marketing expenses during a particular period, excluding the stock-based compensation includedin sales and marketing expenses, by our total new customers added during the same period. We define our total new customers during a particular period as the number of new business entities or individuals who entered into one or more paid subscriptions to our marketing platform, either paid directly or through an agency partner, during the period. We do not include in total new customers business entities or individuals with one or more paid subscriptions solely for our Sidekick product. A single new customer may have separate paid subscriptions for separate websites, but we count these as one new customer if the subscriptions are managed by the same business entity or individual.

We derive our revenue from two major sources, revenue from subscriptions to our inbound platform and professional services and other revenue consisting mainly of on-boarding and training services fees.

Subscription based revenue is derived from customers using our software platform for their inbound marketing and sales needs. Our software platform includes integrated applications that allow businesses to manage social media, search engine optimization, blogging, website content, marketing automation, email,

50

analytics and reporting. Substantially all of our customers’ subscriptions are one year or less in duration. Subscriptions are non-cancelable and are billed in advance on various schedules. All subscription fees that are billed in advance of service are recorded in deferred revenue. Subscription based revenue is recognized net of consideration paid to marketing agency partners when the agency partner purchases the subscription directly from us, as in these instances our customer is the partner and our remaining obligations are to the partner.

Professional services and other revenue are derived primarily from customer on-boarding and training services. The on-boarding and training services provided to customers typically involves an implementation specialist. An implementation specialist will typically work with our customers to enhance their understanding of how to attract leads and convert them into customers through search engine optimization, social media, blogging and other content. Training is generally sold in connection with a customer’s initial subscription and is billed in advance. The training is also available to be purchased separately following a customer’s purchase of its initial subscription and our marketing agency partners routinely provide the same training to customers.

Cost of Revenue and Operating Expenses

Cost of Revenue

Cost of subscription revenue consists primarily of managed hosting providers and other third-party service providers, employee-related costs including payroll, benefits and stock-based compensation expense for our customer support team, amortization of capitalized software development costs and acquired technology, and allocated overhead costs, which we define as rent, facilities and costs related to information technology, or IT.

Cost of professional services and other revenue consists primarily of personnel costs of our professional services organization, including salaries, benefits, bonuses and stock-based compensation, as well as allocated overhead costs.

We expect that cost of subscription and professional services and other revenue will increase in absolute dollars as we continue to invest in growing our business. Over time, we expect to gain benefits of scale associated with our costs of hosting our software platform relative to subscription revenues, resulting in improved subscription gross margin. We expect to continue to generate negative gross margins related to professional services in the near term.

Research and Development

Research and development expenses consist primarily of personnel costs of our development team, including payroll, benefits and stock-based compensation expense and allocated overhead costs. We capitalize certain software development costs that are attributable to developing new products and adding incremental functionality to our software platform and amortize such costs as costs of subscription revenue over the estimated life of the new product or incremental functionality, which is generally two years. We focus our research and development efforts on improving our products and developing new ones, delivering new functionality and enhancing the customer experience. We believe delivering new functionalities for our customers is an integral part of our solution and provides our customers with access to a broad array of options and information critical to their marketing efforts. We expect to continue to make investments in and expand our offerings to enhance our customers’ experience and satisfaction and attract new customers. We expect research and development expenses to increase in absolute dollars as we continue to increase the functionality of our software platform.

Sales and Marketing

Sales and marketing expenses consist primarily of personnel costs of our sales and marketing employees, including sales commissions and incentives, benefits and stock-based compensation expense, marketing programs, including lead generation, costs of our annual INBOUND conference, and other brand building

51

expenses and allocated overhead costs. We defer certain sales commissions related to acquiring new customers and amortize them ratably over the term of the corresponding subscription agreement. Sales and marketing expenses also include commissions paid to our marketing agency partners when we are the primary obligor for providing the subscription that has been purchased.

We plan to continue to expand sales and marketing to grow our customer base and increase sales to existing customers. This growth will include adding sales personnel and expanding our marketing activities to continue to generate additional leads and build brand awareness. We expect sales and marketing expenses will increase as a result of hiring net new quota-carrying sales representatives in the United States and worldwide, adding to the marketing staff and expanding our annual INBOUND conference. Over time, we expect sales and marketing expenses will decline as a percentage of total revenue.

General and Administrative

General and administrative expenses consist of personnel costs and related expenses for executive, finance, legal, human resources, employee-related information technology, administrative personnel, including payroll, benefits and stock-based compensation expense; professional fees for external legal, accounting and other consulting services; and allocated overhead costs. We expect that general and administrative expenses will increase on an absolute dollar basis but decrease as a percentage of total revenue as we focus on processes, systems and controls to enable the our internal support functions to scale with the growth of our business. We also anticipate continuing increases to general and administrative expenses as we incur the costs of compliance associated with being a publicly traded company, including audit and consulting fees.

Other Income (Expense)

Other income (expense) consists primarily of interest expense and foreign currency gains and losses. We have historically had a minimal amount of debt outstanding on which we pay interest. The addition of our Dublin, Ireland office in 2013 and our Sydney, Australia office in 2014 has increased our exposure to foreign currencies, particularly the Euro.

Income Tax Benefit

The income tax benefit consists of current and deferred taxes for U.S. and foreign income taxes. We have historically had a taxable loss in our most significant jurisdictions and full valuation allowance against the majority of our deferred tax assets. We expect this to continue in 2015.

The growth in total customers was primarily driven by our increased sales representative capacity to meet market demand. The increase in average subscription revenue per customer was driven primarily by existing customers increasing their use of our products, existing customers purchasing additional subscriptions and new customers purchasing our higher price product plans.

The 40% increase in professional services and other revenue resulted primarily from the delivery of training services for subscriptions sold.

Liquidity and Capital Resources

Our principal sources of liquidity are cash and cash equivalents, net accounts receivable and our credit facility. In connection with our IPO, we received aggregate net proceeds of $130.8 million. Prior to our IPO, we funded our operations primarily through issuances of convertible preferred stock, debt and proceeds from the exercises of options.

The following table shows cash and cash equivalents, working capital, net cash and cash equivalents used in operating activities, net cash and cash equivalents used in investing activities, and net cash and cash equivalents provided by financing activities for the years ended December 31, 2014, 2013 and 2012:

	Year Ended December 31,
	2014			2013			2012
	(in thousands)
Cash and cash equivalents	$	123,721		$	12,643		$	41,097
Working capital		90,081			(10,859	)		24,218
Net cash and cash equivalents used in operating activities		(12,464	)		(19,808	)		(5,807	)

Net cash and cash equivalents provided by financing activities		134,437			514			35,335

Our cash and cash equivalents at December 31, 2014 was held for working capital purposes. We believe our working capital is sufficient to support our operations for at least the next 12 months. At December 31, 2014, $2.9 million of our cash and cash equivalents was held in accounts outside the United States. These funds would be subject to U.S. federal taxation if repatriated, with such tax liability partially offset by foreign tax credits. Any potential tax impact of repatriating these funds would be immaterial to the financial statements. We do not intend to repatriate these funds.

Net Cash and Cash Equivalents Used in Operating Activities

Net cash and cash equivalents used in operating activities consists primarily of net loss adjusted for certain non-cash items, including stock-based compensation, depreciation and amortization and other non-cash charges, net. We expect that we will continue to use cash in operating activities in 2015 as we continue to invest in and grow our business.

Net cash and cash equivalents used in operating activities during the year ended December 31, 2014 primarily reflected our net loss of $48.2 million, offset by non-cash expenses that included $5.7 million of depreciation and amortization, $16.4 million in stock-based compensation, $0.6 million of provision for doubtful accounts, $0.3 million of non-cash rent expense, and $0.2 million on non-cash income related to unrealized foreign currency gains. Working capital sources of cash and cash equivalents included a $17.1 million increase in deferred revenue primarily resulting from the growth in the number of customers invoiced during the period, a $1.5 million increase in deferred rent associated with reimbursements by our landlord for leasehold improvements, and a $4.7 million increase in accrued expenses as a result of increased expense related to overall growth of the company. These sources of cash and cash equivalents were offset by a $7.9 million increase in accounts receivable as a result of increased billings to customers consistent with the overall growth of the business, and a $2.0 million decrease in deferred commissions expense.

Net cash used in operating activities during 2013 primarily reflected our net loss of $34.3 million, offset by non-cash expenses that included $4.5 million of depreciation and amortization, $3.5 million in stock-based compensation, $0.5 million of provision for doubtful accounts and $0.9 million of non-cash rent expense. Working capital sources of cash included an $8.8 million increase in deferred revenue primarily resulting from the growth in the number of customers invoiced during the period and a $4.3 million increase in accrued expenses as a result of a higher level of expenses consistent with the overall growth of the business. These sources of cash were offset by a $2.5 million decrease in accounts receivable as a result of increased billings to customers consistent with the overall growth of the business, a $3.4 million decrease in prepaid expenses and other assets resulting from a prepayment to one of our third party hosting service providers, a $1.2 million decrease in accounts payable resulting from paying down our accounts payable after year-end, and a $1.2 million

60

decrease in deferred commission expense due to increased commission costs consistent with the overall growth of the business. The change in net cash used in operating activities from 2012 to 2013 is primarily due to increases in payments for employee payroll as we continued to invest in and grow our business.

Net cash used in operating activities during 2012 primarily reflected our net loss of $18.8 million, offset by non-cash expenses that included $2.7 million of depreciation and amortization, $2.5 million in stock-based compensation, $0.4 million of provision for doubtful accounts and $0.1 million of interest expense. Working capital sources of cash included a $7.8 million increase in deferred revenue due to the growth in the number of customers invoiced during the period, a $2.1 million increase in accrued expenses resulting from a higher level of expenses consistent with the overall growth of the business and a $1.2 million increase in accounts payable as a result of paying down incremental payables after year-end. These sources of cash were partially offset by a $3.1 million decrease in accounts receivable as a result of increased billings to customers consistent with the overall growth of the business. Net cash used in operating activities decreased from 2011 compared to 2012 because we sold more subscriptions with upfront payment terms and did not increase our headcount during the first half of 2012 at the same rate as we did in 2011.

Net Cash and Cash Equivalents Used in Investing Activities

Our investing activities have consisted primarily of property and equipment purchases for computer-related equipment and capitalization of software development costs. Capitalized software development costs are related to new products or improvements to our existing software platform that expands the functionality for our customers. As our business grows, we expect that we will continue to invest in the expansion of, and improvements to, our leased spaces, both domestically and internationally.

Net cash and cash equivalents used in investing activities during the year ended December 31, 2014 was $10.5 million. This consisted primarily of $7.3 million of purchased property and equipment and $4.6 million of capitalized software development costs, offset by $1.5 million of cash released from restrictions associated with the lease of our headquarters. In the year ended December 31, 2014 we continued to invest in improvements to our leased spaces.

Net cash used in investing activities during 2013 was $9.2 million. This consisted primarily of $4.4 million of purchased property and equipment and $3.4 million of capitalized software development costs. In 2013, we expanded our operations and the leased space of our headquarters in Cambridge, Massachusetts, and also invested in improvements to the leased space. In addition, we were required to restrict a portion of our cash balance as a security deposit for the additional leased space.

Net cash used in investing activities during 2012 was $2.4 million. This consisted primarily of $0.3 million to purchase property and equipment and $2.3 million of capitalized software development costs.

Net Cash and Cash Equivalents Provided by Financing Activities

Our primary financing activities have consisted primarily of our IPO, issuances of convertible preferred stock, draw-downs and a repayment on our line of credit, and proceeds from the exercise of options.

For the year ended December 31, 2014 cash and cash equivalents provided by financing activities consisted primarily of $130.8 million of net proceeds received from our IPO, $3.8 million from option exercises, and $18.0 million of draw-downs and offsetting repayments under our line of credit.

For the year ended December 31, 2013, cash provided by financing activities consisted primarily of $0.6 million of proceeds received from option exercises and was offset by $0.1 million used to repay capital leases.

61

For the year ended December 31, 2012, cash provided by financing activities was $35.3 million, consisting primarily of $35.1 million of net proceeds received from the issuance of Series E preferred stock and $0.7 million of proceeds received from option exercises, and was offset by $0.4 million used to repay long-term debt and $0.1 million used to repay capital leases.

During the year ended December 31, 2014 we increased our credit facility to a total of $35.0 million and extended the term we could borrow through March 2016.

Critical Accounting Policies and Estimates

Our management’s discussion and analysis of financial condition and results of operations is based on our consolidated financial statements which have been prepared in accordance with accounting principles generally accepted in the United States of America. In preparing our financial statements, we make estimates, assumptions and judgments that can have a significant impact on our reported revenues, results of operations and net income or loss, as well as on the value of certain assets and liabilities on our balance sheet during and as of the reporting periods. These estimates, assumptions and judgments are necessary because future events and their effects on our results and the value of our assets cannot be determined with certainty, and are made based on our historical experience and on other assumptions that we believe to be reasonable under the circumstances. These estimates may change as new events occur or additional information is obtained, and we may periodically be faced with uncertainties, the outcomes of which are not within our control and may not be known for a prolonged period of time. Because the use of estimates is inherent in the financial reporting process, actual results could differ from those estimates.

Revenue Recognition

We primarily generate revenue from multiple element arrangements, which typically include subscriptions to our online software solution and on-boarding and training services. Our customers do not have the right to take possession of the online software solution. Revenue from subscriptions, including additional fees for items such as incremental contacts, is recognized ratably over the subscription period beginning on the date the subscription is made available to customers. Substantially all subscription contracts are one year or less. We recognize revenue from on-boarding and training services as the services are provided. Amounts billed that have not yet met the applicable revenue recognition criteria are recorded as deferred revenue.

As part of accounting for multiple element arrangements, we must assess if each component has value on a standalone basis and should be treated as a separate unit of accounting. There is an in-depth process that we undergo to determine the standalone value for each component where we determine if an individual component could be sold by itself or if the component is sold by other third parties. If the component has standalone value upon delivery, we account for each component separately. Subscription services have standalone value as they are often sold separate from all other services. On-boarding and training services also have standalone value as they are sold separately by us and by third parties.

We allocate total arrangement fees to each element in a multiple element arrangement based on the relative selling price hierarchy of each element. We are not able to establish vendor-specific objective evidence, or VSOE, the most reliable level of allocating standalone value, for our subscription and on-boarding and training services because of our pricing practices. We note that third party evidence, or TPE, the second most reliable level of allocating standalone value, is not appropriate for determining the standalone value for any of our services because the pricing for any similar third party subscription or on-boarding and training services is inconsistent. Therefore, we rely on best estimate of selling price, or BESP, to allocate value to the various components of our arrangements.

To determine BESP, we consider the median actual sales price of each type of subscription and on-boarding and training services. We then establish a reasonable range around the median pricing, typically plus or minus 20% of the median selling price. For any transactions where a deliverable falls outside of this range, we reallocate arrangement consideration amongst the deliverables using their respective median selling prices.

62

We pay our marketing agency partners a commission on the subscription sales price for sales to customers. The classification of the commission paid on our consolidated statements of operations depends on who is purchasing our subscription. In instances where the customer is purchasing the subscription, we are the primary obligor and record the commission paid to the agency partner as sales and marketing expense. When the agency partner purchases the subscription directly from us, we net the consideration paid to the partner against the associated revenue we recognize, as in these instances our customer is the partner and our remaining obligations are to the partner. We also do not believe we receive a tangible benefit from the payment back to the partner.

If our judgments change we would not expect to see a material effect on our consolidated financial statements.

Capitalized Software Development Costs

Software development costs consist of certain payroll and stock compensation costs incurred to develop functionality for our software platform, as well as certain upgrades and enhancements that are expected to result in enhanced functionality. We capitalize certain software development costs for new offerings as well as upgrades to our existing software platform. We amortize these development costs over the estimated useful life of two years on a straight-line basis. We believe there are two key estimates within the capitalized software balance, which are the determination of the useful life of the software and the determination of the amounts to be capitalized.

We determined that a two year life is appropriate for our internal-use software based on our best estimate of the useful life of the internally developed software after considering factors such as continuous developments in the technology, obsolescence and anticipated life of the service offering before significant upgrades. Based on our prior experience, internally generated software will generally remain in use for a minimum of two years before being significantly replaced or modified to keep up with evolving customer needs. While we do not anticipate any significant changes to this two year estimate, a change in this estimate could produce a material impact on our financial statements. For example, if we received information that indicated the useful life of all internally developed software was one year rather than two, our capitalized software balance would decrease by approximately 50% and our amortization expense would increase by 50% in the year of adoption of the change in estimate.

We determine the amount of internal software costs to be capitalized based on the amount of time spent by our developers on projects. Costs associated with building or significantly enhancing our software platform are capitalized, while costs associated with planning new developments and maintaining our software platform are expensed as incurred. There is judgment involved in estimating the stage of development as well as estimating time allocated to a particular project. A significant change in the time spent on each project could have a material impact on the amount capitalized and related amortization expense in subsequent periods.

Stock-Based Compensation

We recognize compensation expense for option awards based on the fair value of the award and on a straight-line basis over the vesting period of the award based on the estimated portion of the award that is expected to vest.

Inherent in the valuation and recording of stock-based compensation for option awards, there are several estimates that we make, including in regard to valuation and expense that will be incurred. We apply estimated forfeiture rates to the awards based on analyses of historical data, including termination patterns, employee position and other factors. This is done to record the expense we expect to actually incur for employees that provide the required service time.

We use the Black-Scholes option pricing model to measure the fair value of our option awards when they are granted. Prior to our IPO, we estimated the value of common stock at the grant date with the help of an

63

independent third party service provider. See “Valuation of Common Stock” below for further discussion of the valuation process. For stock options and RSUs granted subsequent to our IPO, our board of directors determined the fair value based on the closing price of our common stock as reported on the New York Stock Exchange on the date of grant. We used the daily historical volatility of companies we consider to be our peers. To determine our peer companies, we used the following criteria: software or software-as-a-service companies; similar histories and relatively comparable financial leverage; sufficient public company trading history; and in similar businesses and geographical markets. We used the peers’ stock price volatility over the expected life of our granted options to calculate the expected volatility. The expected term of employee option awards is determined using the average midpoint between vesting and the contractual term for outstanding awards, or the simplified method, because we do not yet have a sufficient history of option exercises. We consider this appropriate as we plan to see significant changes to our equity structure in the future and there is no other method that would be more indicative of exercise activity. The risk-free interest rate is based on the rate on U.S. Treasury securities with maturities consistent with the estimated expected term of the awards. We have not paid dividends and do not anticipate paying a cash dividend in the foreseeable future and, accordingly, use an expected dividend yield of zero.

The following table summarizes the assumptions, other than fair value of our common stock, relating to our stock options granted in the years ended December 31, 2014, 2013, and 2012:

	Year Ended December 31,
	2014			2013			2012
Dividend yield		—			—			—
Expected volatility		44.8-50.9	%		46.8-54.7	%		48-51	%
Risk-free interest rate		1.79-2.67	%		0.82-1.86	%		0.56-1.23	%
Expected term (in years)		5.0-6.5			4.6-6.5			3.5-6.5

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 expense 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. 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 share-based compensation expense recognized in our financial statements.

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

During 2013 and 2014, we granted 1.5 million RSUs, to certain directors, executives and key employees. Our stock-based compensation expense for RSUs is estimated at the grant date based on the fair value of our common stock. The RSUs vest upon the satisfaction of both a service condition and a performance condition. The service condition for a majority of the RSUs is satisfied over a period of four years. The performance condition will be satisfied on the earlier of (i) a sale of our company or (ii) the date that is six months following our initial public offering, in either case, prior to the earlier of (A) the expiration date or (B) the tenth anniversary of the grant date.

In the year ended December 31, 2013, no stock-based compensation expense had been recognized for RSUs because a qualifying event for the awards’ vesting was not probable. In the fourth quarter of 2014, the quarter in which our IPO was completed, we began recording stock-based compensation expense based on the grant-date

64

fair value of the RSUs, using the accelerated attribution method for RSUs granted prior to our IPO and using the straight-line method for RSUs granted following our IPO, in each case, net of estimated forfeitures. The stock compensation expense associated with RSUs where the service condition had been met prior to the IPO was also recognized on the date of the IPO, using the accelerated attribution method.

The following table estimates future stock-based compensation expense related to all outstanding equity awards, net of estimated forfeitures. The table does not take into account any stock-based compensation expense related to future awards that may be granted to employees, directors, or other service providers.

Valuation of Common Stock

Given the absence of an active market for our common stock prior to our IPO, our board of directors was required to estimate the fair value of our common stock at the time of each option grant based upon several factors, including its consideration of input from management and contemporaneous third-party valuations.

The exercise price for all stock options granted was at the estimated fair value of the underlying common stock, as estimated on the date of grant by our board of directors in accordance with the guidelines outlined in the American Institute of Certified Public Accountants, Valuation of Privately-Held-Company Equity Securities Issued as Compensation . Each fair value estimate was based on a variety of factors, which included the following:

• our historical operating and financial performance;

• a discounted cash flow analysis;

• the market performance of comparable publicly traded technology companies;

• the identification and analysis of mergers and acquisitions of comparable technology companies;

• the prices, rights, preferences and privileges of our preferred stock relative to the common stock;

• the likelihood of achieving a liquidity event such as an initial public offering or sale given prevailing market conditions and the nature and history of our business;

• any adjustments necessary to recognize a lack of marketability for our common stock; and

• U.S. and global economic market conditions.

In connection with these fair value estimates for grants prior to September 2014, our common stock was generally estimated or reconciled using an income and market approach.

Under the income approach, the enterprise value is estimated by performing a discounted cash flow, or DCF, analysis. The fair value of our common stock determined in connection with the grants prior to 2014, was 50% weighted using the DCF analysis. The fair value of our common stock determined in connection with the grants made in 2014 was 40% weighted using the DCF analysis. The DCF analysis requires the development and analysis of the forecasted future financial performance of the company, including revenues, operating expenses and taxes, as well as working capital and capital asset requirements. The discrete forecast period analyzed extends to the point at which the company will be expected to have reached a steady state of growth and profitability. The projected cash flows are then discounted to a present value employing a discount rate that properly accounts for the estimated market weighted average cost of capital, as well as any risk unique to our cash flows. Finally, an assumption is made regarding the sustainable long-term rate of growth beyond the discrete forecast period, and a residual value is estimated and discounted to a present value. The sum of the present value of the discrete cash flows and the residual, or “terminal,” value represents the estimated fair value of the total enterprise value of the company. This value is then adjusted for non-operational assets, liabilities and interest bearing debt to conclude the equity value of the company.

Under the market approach, the enterprise value is estimated by performing a guideline public company, or GPC analysis, and a guideline transaction, or GT, analysis. The fair value of our common stock determined in

66

connection with the grants prior to 2014, was 30% weighted using the GPC analysis and 20% using the GT analysis. The fair value of our common stock determined in connection with the grants made in 2014 were 40% weighted using the GPC analysis and 20% using the GT analysis.

The GPC analysis is based upon the premise that indications of value for a given entity can be estimated based upon the observed valuation multiples of comparable public companies, the equity of which is freely-traded by investors in the public securities markets. The first step in this analysis involves the selection of a peer group of companies from which it is believed relevant data can be obtained. The second step involves the calculation of the relevant valuation multiple or multiples for each company in the peer group. The final step involves the selection and application of the appropriate multiples to the relevant financial metrics of our company. Depending upon the nature of the multiple, the resulting value indication may then be adjusted for non-operational assets, liabilities and interest bearing debt to conclude the equity value of the company.

The guideline transaction analysis is based upon the premise that indications of value for a given entity can be estimated based upon the valuation multiples implied by transactions involving companies that are comparable to the subject company. The first step in this analysis involves the identification of transactions from which it is believed relevant data can be obtained. The second step involves the calculation of the relevant valuation multiple or multiples for each transaction in the comparable group. The final step involves the selection and application of the appropriate multiples to the relevant financial metrics of our company. Depending upon the nature of the multiple, the resulting value indication may then be adjusted for non-operational assets, liabilities and interest bearing debt to conclude the equity value.

Once the equity value is estimated it is then allocated among the various classes of securities to arrive at the fair value of the common stock. For this allocation, the OPM was used for all grants. The OPM entails allocating the equity value to the various share classes based upon their respective claims on a series of call options with strike prices at various value levels depending upon the rights and preferences of each class. A Black-Scholes option pricing model is employed to value the options, with an option term assumption consistent with management’s expected time to a liquidity event and a volatility assumption based on the estimated stock price volatility of a peer group of comparable public companies over a similar term. The differential in value between each successive option represents the value of that tranche, which is then allocated to all the share classes based on their percentage ownership claim at that level of value.

For each grant date the board and management estimated two different liquidity event scenarios (non-initial public offering and initial public offering) which were then applied to two different option pricing models (non- initial public offering and initial public offering) and weighted based on the board management’s expectations.

Applying the non- initial public offering and initial public offering OPMs result in an estimated marketable, minority fair value of our common stock for each grant date. A discount for lack of marketability, or DLOM, based both on an option based approach (put option) and empirical evidence from sources incorporating studies of companies with characteristics similar to ours is then applied, yielding a fair value of our common stock on a non-marketable, minority interest basis.

In connection with the determination by our board of directors of the fair value of our common stock for purposes of the September 25, 2014 equity grants, we assumed the completion of our IPO and that a public market for our common stock had been created. We also considered the valuation range proposed by the underwriters, evidenced by the estimated offering price range set forth on the cover page of the preliminary prospectus dated September 26, 2014 in connection with our IPO relative to our financial results, current economic and market conditions, the removal of any illiquidity discount and a 100% weighting that we would complete this offering. After such considerations, our board of directors determined the fair value of our common stock to be $20.00 per share as of September 25, 2014, which was the midpoint of the estimated offering price range reflected on the cover page of the preliminary prospectus dated September 26, 2014 in connection with our IPO, and granted stock options with an exercise price of $20.00 per share as well as RSUs on such date.

67

For stock options and RSUs granted subsequent to our IPO, our board of directors determined the fair value based on the closing price of our common stock as reported on the New York Stock Exchange on the date of grant.

Goodwill Impairment

Goodwill represents the excess of the cost of an acquired entity over the net fair value of the identifiable assets acquired and liabilities assumed. Goodwill is not amortized, but rather is assessed for impairment at least annually. We perform our annual impairment assessment on November 30 of each year. We operate under one reporting unit and as a result, evaluate goodwill impairment based on our fair value as a whole.

To determine the number of operating segments and reporting units that are present, we analyzed whether there is any customer, product or geographic information that drives the chief operating decision maker (our chief executive and operating officers) decisions on how to allocate resources and whether any segment management exists. Management has concluded that operating decisions are made at the consolidated company level and there is no segment management in place that reviews results of operations with the chief operating decision maker.

In assessing goodwill for impairment, an entity has the option to assess qualitative factors to determine whether events or circumstances indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, it is more likely than not that the fair value of the reporting unit is greater than its carrying value, then performing the two-step impairment test is unnecessary. An entity can choose not to perform a qualitative assessment for any of its reporting units, and proceed directly to the use of the two-step impairment test.

When assessing goodwill for impairment for the year ended December 31, 2014, we decided to use the two-step quantitative analysis. We determined our enterprise value used a weighted average of (1) an income approach using a discounted cash flow analysis and (2) a market approach using comparable public company metrics to determine the fair value of our one reporting unit, the consolidated company. Based on the results of our most recent annual assessment performed on November 30, 2014, we concluded that the fair value of our reporting unit exceeded its carrying amount and there was no impairment of goodwill.

Contractual Obligations and Commitments

Contractual obligations are cash that we are obligated to pay as part of certain contracts that we have entered during our course a business. Below is a table that shows the projected outlays as of December 31, 2014:

			Payments due in:
	Total		Less than 1 Year		1-3 Years		3-5 Years		More than 5 Years
	(in thousands)
Capital lease obligation	$	187	$	107	$	80	$	—	$	—
Operating leases obligations		35,611		5,350		12,230		12,324		5,707
Total	$	35,798	$	5,457	$	12,310	$	12,324	$	5,707

In October 2013, we extended our capital lease agreement for the purchase of equipment and financing of maintenance and installation costs with an original fair value of $299,000. The lease is payable in 36 monthly payments through September 2016. The total outstanding balance, including interest, financed under capital leases was $324,000 as of December 31, 2013 and $187,000 as of December 31, 2014.

We lease our office facilities under non-cancelable operating leases. As of December 31, 2014, we have leases that expire at various dates through 2020.

68

Off Balance Sheet Arrangements

We have no material off-balance sheet arrangements at December 31, 2013 and 2014, exclusive of operating leases and indemnifications on officers, directors and employees for certain events or occurrences while the officer, director or employee is, or was, serving at our request in such capacity.

For information on recent accounting pronouncements, see Recently Accounting Pronouncements in the notes to the consolidated financial statements appearing elsewhere in this Annual Report on Form 10-K.

ITEM 7A. Qualitative and Quantitative Disclosures About Market Risk

Foreign Currency Exchange Risk

We are not currently subject to significant foreign currency exchange risk. However, we have foreign currency risks related to our revenue and operating expenses denominated in currencies other than the U.S. dollar, primarily the Euro and British Pound Sterling. Decreases in the relative value of the U.S. dollar to other currencies may negatively affect our revenue and other operating results as expressed in U.S. dollars.

We have experienced and will continue to experience fluctuations in our net loss as a result of transaction gains or losses related to revaluing certain current asset and current liability balances that are denominated in currencies other than the functional currency of the entities in which they are recorded. We recognized immaterial amounts of foreign currency gains and losses in each of the three years presented. We have not engaged in the hedging of our foreign currency transactions to date, we are evaluating the costs and benefits of initiating such a program and may in the future hedge selected significant transactions denominated in currencies other than the U.S. dollar as we expand our international operation and our risk grows.

Interest Rate Sensitivity

We hold cash and cash equivalents for working capital purposes. We do not have material exposure to market risk with respect to investments, as any investments we enter into are primarily highly liquid investments. We have a revolving credit line which we have not utilized as of December 31, 2014. The interest rate associated with the revolving line is the prime lending rate plus 0.5%. A 10% increase or decrease in interest rates would not result in a material change in either our obligations under the line of credit, even at the borrowing limit, or in the returns on our cash in 2014.

Inflation Risk

We do not believe that inflation has had a material effect on our business. However, if our costs, in particular personnel, sales and marketing and hosting costs, were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases. Our inability or failure to do so could harm our business, operating results and financial condition.

Emerging Growth Company Status

Section 107 of the Jumpstart Our Small Business Startups Act, or JOBS Act, provides that an “emerging growth company” can take advantage of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards. However, we elected to “opt out” of such extended transition period, and as a result, we comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. Section 107 of the JOBS Act provides that our decision to not take advantage of the extended transition period for complying with new or revised accounting standards is irrevocable.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

HubSpot, Inc.

Cambridge, Massachusetts

We have audited the accompanying consolidated balance sheets of HubSpot, Inc. and subsidiaries (the “Company”) as of December 31, 2014 and 2013, and the related consolidated statements of operations, comprehensive loss, redeemable convertible preferred stock and stockholders’ equity (deficit), and cash flows for each of the three years in the period ended December 31, 2014. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements 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 audit 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 consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2014 and 2013, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2014, in conformity with accounting principles generally accepted in the United States of America.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Operations

HubSpot, Inc. (the “Company”), was formed as a limited liability company in Delaware on April 4, 2005. The Company converted to a Delaware corporation on June 7, 2007. The Company provides a cloud-based inbound marketing and sales platform which features integrated applications to help businesses attract visitors to their websites, convert visitors into leads, close leads into customers and delight customers so they become promoters of those businesses. These integrated applications include social media, search engine optimization, blogging, website content management, marketing automation, email, CRM, analytics, and reporting.

The Company is headquartered in Cambridge, Massachusetts, and has wholly-owned subsidiaries in Dublin, Ireland, which commenced operations in January of 2013 and in Sydney, Australia, which commenced operations in August of 2014.

On September 25, 2014, the Company’s Board of Directors and stockholders approved a 1-for-3 reverse stock split of the Company’s common stock. All references made to share or per share amounts in the accompanying consolidated financial statements and applicable disclosures have been retroactively adjusted to reflect the Stock Split. See Note 10 for additional information about the Stock Split.

On October 15, 2014, the Company closed its initial public offering (“IPO”) whereby 5,750,000 shares of common stock were sold to the public, including the underwriters’ overallotment option of 750,000 shares of common stock, at a price of $25.00 per share. The Company received aggregate proceeds of approximately $133.7 million from the IPO, net of underwriters’ discounts and commissions, but before deduction of offering expenses of approximately $3.1 million. Upon the closing of the IPO, all shares of the Company’s outstanding convertible preferred stock automatically converted into 19,529,713 shares of common stock.

All restricted stock units, or RSUs, granted to employees prior to the IPO vest upon the satisfaction of both a service condition and a performance condition. The service condition for a majority of the RSUs is satisfied over a period of four years. The performance condition will be satisfied on the date that is six months following the Company’s IPO. No stock-based compensation expense was recognized for RSUs prior to the IPO because an IPO is not considered probable until it occurs. Upon completion of the Company’s IPO the Company began recording stock-based compensation expense based on the grant-date fair value of the RSUs using the accelerated attribution method for RSUs granted prior to its IPO and using the straight-line method for RSUs granted following its IPO, net of estimated forfeitures. The stock compensation expense associated with RSUs where the service condition had been met prior to the IPO was also recognized on the date of the IPO, using the accelerated attribution method.

2. Summary of Significant Accounting Policies

Basis of Presentation—The consolidated financial statements have been prepared in U.S. dollars, in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. All intercompany transactions have been eliminated in consolidation.

Use of Estimates—The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Operating Segments—The Company operates as one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is regularly evaluated by the chief

77

operating decision makers (“CODMs”), which are the Company’s chief executive officer and chief operating officer, in deciding how to allocate resources and assess performance. The Company’s CODMs evaluate the Company’s financial information and resources and assess the performance of these resources on a consolidated basis. Since the Company operates in one operating segment, all required financial segment information can be found in the consolidated financial statements.

Historical Loss Per Share—Basic net loss per share attributable to common stockholders is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period. 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, options to purchase common stock, common stock warrant, nonvested shares of restricted stock, RSUs and redeemable convertible preferred stock are considered to be common stock equivalents. The Company applied the two-class method to calculate its basic and diluted net loss per share of common stock, as its convertible preferred stock and common stock are participating securities. The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common stockholders. However, the two-class method does not impact the net loss per share of common stock as the Company was in a loss position for each of the periods presented and preferred stockholders do not participate in losses.

A reconciliation of the denominator used in the calculation of basic and diluted loss per share is as follows:

	Year Ended December 31,
	2014			2013			2012
	(in thousands, except per share amounts)
Numerator:
Net loss attributable to common stockholders	$	(48,560	)	$	(34,328	)	$	(18,859	)
Denominator:
Weighted-average common shares outstanding—basic		11,562			5,113			4,699
Dilutive effect of share equivalents resulting from stock options, RSUs, nonvested restricted stock, common stock warrant and redeemable convertible preferred shares (as converted)		—			—			—
Weighted-average common shares outstanding-diluted		11,562			5,113			4,699
Net loss per common share, basic and diluted	$	(4.20	)	$	(6.71	)	$	(4.01	)

For the years ended December 2014, 2013 and 2012, the Company incurred net losses and, therefore, the effect of the Company’s outstanding stock options, common stock warrant, redeemable convertible preferred stock, RSUs and nonvested shares of restricted stock was not included in the calculation of diluted loss per share as the effect would be anti-dilutive. The following table contains share totals with a potentially dilutive impact (in thousands):

	Year Ended December 31,
	2014		2013		2012
	(in thousands)
Options to purchase common shares		4,588		4,695		4,180

Convertible preferred shares (as converted)		—		19,530		19,530
RSUs		1,376		858		—

78

Cash and Cash Equivalents—The Company considers all highly liquid investments purchased with original maturity of three months or less to be cash equivalents. Cash and cash equivalents consist of cash held in bank deposit accounts and short-term, highly-liquid investments with remaining maturities of three months or less at the date of purchase, consisting of money-market funds.

Restricted Cash—The Company had restricted cash of $230 thousand at December 31, 2014 related to a leased facility. The Company had restricted cash of $1.9 million at December 31, 2013 which included $1.8 million for letters of credit for the Company’s leased facilities and $157 thousand in collateral for the Company’s corporate credit card borrowings. During the year ended December 31, 2014 the Company released from restrictions $1.7 million of cash, which includes the $157 thousand in collateral related to the Company’s corporate credit card borrowings and $1.5 million related to its leased facilities.

Accounts Receivable and Allowance for Doubtful Accounts—Accounts receivable are carried at the original invoiced amount less an allowance for doubtful accounts based on the probability of future collection. When management becomes aware of circumstances that may decrease the likelihood of collection, it records a specific allowance against amounts due, which reduces the receivable to the amount that management reasonably believes will be collected. For all other customers, management determines the adequacy of the allowance based on historical loss patterns, the number of days that billings are past due and an evaluation of the potential risk of loss associated with specific accounts. To date, losses resulting from uncollected receivables have not exceeded management’s expectations.

The following is a rollforward of the Company’s allowance for doubtful accounts (in thousands):

	Balance Beginning of Period		Charged to Costs or Expenses		Deductions (1)			Balance at End of Period
Allowance for doubtful accounts
Year ended December 31, 2014	$	175	$	632	$	(589	)	$	218
Year ended December 31, 2013	$	122	$	523	$	(470	)	$	175
Year ended December 31, 2012	$	61	$	384	$	(323	)	$	122

(1) Deductions include actual accounts written-off, net of recoveries.

Property and Equipment—Property and equipment are stated at cost and depreciated using the straight-line method over the estimated useful lives of the related assets. Expenditures for maintenance and repairs are charged to expense as incurred, whereas major betterments are capitalized as additions to leasehold improvements. Depreciation is recorded over the following estimated useful lives:

	Estimated Useful Life
Computer equipment and purchased software	3 years
Office equipment	5 years
Furniture and fixtures	5 years
Leasehold improvements	Lesser of lease term or useful life

Impairment of Long-Lived Assets—Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable or that the useful lives of those assets are no longer appropriate. Management considers the following potential indicators of impairment of its long-lived assets (asset group): a substantial decrease in the Company’s stock price, a significant adverse change in the extent or manner in which a long-lived asset (asset group) is being used, a significant adverse change in legal factors or in the business climate that could affect the value of the long-lived asset (asset group), an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a long-lived asset (asset group), and a current expectation that, more likely than

79

not, a long lived asset (asset group) will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. When such events occur, the Company compares the carrying amounts of the assets to their undiscounted expected future cash flows. If this comparison indicates that there may be an impairment, the amount of the impairment is calculated as the difference between the carrying value and fair value. For the years presented, the Company did not recognize an impairment charge.

Goodwill—Goodwill represents the excess of cost over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. The Company has no other intangible assets with indefinite useful lives. Goodwill is not subject to amortization, but is monitored annually for impairment or more frequently if there are indicators of impairment. Management considers the following potential indicators of impairment: significant underperformance relative to historical or projected future operating results, significant changes in the Company’s use of acquired assets or the strategy of the Company’s overall business, significant negative industry or economic trends and a significant decline in the Company’s stock price for a sustained period. The Company performs its annual impairment test on November 30. Currently, the Company’s goodwill is evaluated at the entity level as it is determined there is only one reporting unit. The Company performs a two step impairment test. In the first step, the fair value of each reporting unit is compared to its carrying amount. If the fair value exceeds the carrying value of the net assets assigned, goodwill is not considered impaired and the second step is not required. If the carrying value exceeds the fair value, then the second step of the impairment test is performed in order to determine the implied fair value of the reporting unit’s goodwill. If the carrying value of the goodwill exceeds the fair value, then an impairment charge is recorded. On November 30, 2014, the estimated fair value of the Company’s single reporting unit exceeded its carrying amount. Because the fair value of the Company’s single reporting unit was in excess of its carrying value and there were no indicators that the Company’s goodwill had become impaired since that date, there was no impairment as of November 30, 2014 through December 31, 2014.

For the years ended December 31, 2014, 2013 and 2012, the Company did not recognize an impairment charge.

Advertising Expense—The Company expenses advertising as incurred, which is included in sales and marketing expense in the accompanying consolidated statements of operations. The Company incurred $3.3 million of advertising expense in 2014, $3.5 million in 2013, and $3.0 million in 2012.

Revenue Recognition—The Company primarily generates revenue from multi-element arrangements, which typically include subscriptions to its online software solution and professional services which includes on-boarding and training services. The Company’s customers do not have the right to take possession of the online software solution. The Company recognizes revenue when all of the following have occurred:

• persuasive evidence of an arrangement with the customer exists;

• service has been or is being provided;

• the fees are fixed or determinable; and

• collectability of the fees is reasonably assured.

The Company’s arrangements do not contain general rights of return.

In order to treat elements in a multiple-element arrangement as separate units of accounting, the delivered elements must have standalone value and delivery of the undelivered element is probable and within control of the Company.

The Company has determined that subscriptions for its online software solution have standalone value because, once a customer launches its initial site, the online software solution is fully functional and does not require any additional development, modification, or customization.

80

Professional services consists primarily of on-boarding and web-based and in-person training, are not required to use the online software solution, and are determined to have stand-alone value from the related subscription services because they are sold separately by the Company and third parties.

When multiple element arrangements are separated into different units of accounting, the arrangement consideration is allocated to the identified separate units based on a relative selling price hierarchy. The estimated fair value of each element is determined based upon the following hierarchy: (1) vendor specific objective evidence (“VSOE”) of fair value, (2) third party evidence of selling price (“TPE”), or (3) the Company’s best estimate of selling price (“BESP”). The Company is not able to establish VSOE of fair value for undelivered elements, which in most instances is subscription and training and professional services, based on its pricing practices, and there is not a reliable measure of TPE of selling price. As such, arrangement consideration is allocated amongst multiple deliverable arrangements using BESP. The Company establishes BESP for each deliverable primarily considering the median of actual sales prices of each type of subscription and other professional services sold. The Company considers each type of subscription and service as well as pricing and geographic information when establishing BESP. Arrangement consideration is allocated such that the revenue recognized does not exceed the fee subject to refund.

Revenue from subscriptions is recognized ratably over the subscription period beginning on the date the Company’s subscription is made available to customers. Substantially all subscription contracts are one year or less. The Company recognizes revenue from on-boarding and training services as the services are provided.

The Company pays its marketing agency partners a commission of the subscription sales price for sales to customers. The classification of the commission paid on the Company’s consolidated statements of operations depends on who is purchasing its subscription. In instances where the customer is purchasing the subscription, the Company is the primary obligor and records the commission paid to the agency partner as sales and marketing expense. When the agency partner purchases the subscription directly from the Company, the Company nets the consideration paid to the partner against the associated revenue it recognizes, as in these instances the Company’s customer is the partner and the Company’s remaining obligations are to the partner. The Company does not believe that it receives a tangible benefit from the payment back to the partner.

Sales taxes collected from customers and remitted to government authorities are excluded from revenue.

Amounts that have been invoiced are recorded in accounts receivable and deferred revenue or revenue, depending on whether the revenue recognition criteria have been met. Deferred revenue represents amounts billed for which revenue has not yet been recognized. Deferred revenue that will be recognized during the succeeding 12-month period is recorded as current deferred revenue and the remaining portion is recorded as long-term deferred revenue.

Concentrations of Credit Risk and Significant Customers—Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, restricted cash and accounts receivable.

A significant portion of the Company’s cash is held at one financial institution that management believes to be of high credit quality. Although the Company deposits it cash with multiple financial institutions, its deposits exceed federally insured limits.

The Company has no significant off-balance sheet risk such as foreign exchange contracts, option contracts, or other hedging arrangements.

The Company generally does not require collateral from its customers and generally requires payment 30 days from the invoice date. The Company maintains an allowance for doubtful accounts based on its assessment of the collectability of accounts receivable. Credit risk arising from accounts receivable is mitigated as a result of transacting with a large number of geographically dispersed customers spread across various industries.

81

At December 31, 2014 and 2013 there were no customers that represented more than 10% of the net accounts receivable balance. There were no customers that individually exceeded 10% of the Company’s revenue in any of the periods presented.

Foreign Currency—The functional currency of the Company’s foreign subsidiaries is the local currency. Assets and liabilities denominated in a foreign currency are translated into U.S. dollars at the exchange rates in effect at the balance sheet dates; with the resulting translation adjustments directly recorded to a separate component of accumulated other comprehensive income (loss). Income and expense accounts are translated at the weighted-average exchange rates during the period. Equity transactions are translated at historical exchange rates. Foreign currency transaction gains and losses are recorded in other income (expense).

Research and Development—Research and development expenses include payroll, employee benefits and other expenses associated with product development.

Capitalized Software Development Costs—Certain payroll and stock compensation costs incurred to develop functionality for the Company’s software platform, as well as certain upgrades and enhancements that are expected to result in increased functionality are capitalized. The costs incurred in the preliminary stages of development are expensed as incurred. Once an application has reached the development stage, certain internal costs are capitalized until the software is substantially complete and ready for its intended use. Capitalized software development costs are amortized on a straight-line basis over their estimated useful life of two years. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets.

Capitalized software development costs consisted of the following:

	December 31,
	2014			2013
	(in thousands)
Gross capitalized software development costs	$	14,219		$	9,351
Accumulated amortization		(9,786	)		(5,872	)
Capitalized software development costs, net	$	4,433		$	3,479

The Company capitalized software development costs of $4.9 million in 2014, $3.7 million in 2013, and $2.4 million in 2012. Stock-based compensation costs included in capitalized software were $235 thousand in 2014, $273 thousand in 2013, and $100 thousand in 2012.

Amortization of capitalized software development costs was $3.9 million in 2014, $2.6 million in 2013, and $1.5 million in 2012. Amortization expense is included in cost of revenue in the consolidated statements of operations.

Income Taxes—Deferred tax assets and liabilities are recognized for the differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities using tax rates expected to be in effect in the years in which the differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will not be realized.

The Company provides reserves for potential payments of tax to various tax authorities related to uncertain tax positions based on a determination of whether and how much of a tax benefit taken by the Company in its tax filings or positions is more likely than not to be realized following resolution of any potential contingencies present related to the tax benefit. Potential interest and penalties associated with such uncertain tax positions are recorded as a component of income tax expense.

82

Stock-Based Compensation—The Company accounts for all stock options and awards granted to employees and nonemployees using a fair value method. Stock-based compensation is recognized as an expense and is measured at the fair value of the award. The measurement date for employee awards is generally the date of the grant. The measurement date for nonemployee awards is generally the date the options vest. Stock-based compensation costs are recognized as expense over the requisite service period, which is generally the vesting period for awards, on a straight-line basis for awards with only a service condition, and using the graded-method for awards with both a performance and service that were granted prior to our IPO, and on a straight-line basis for the awards that were granted following our IPO.

Recent Accounting Pronouncements—In May 2014, the Financial Accounting Standards Board issued updated guidance and disclosure requirements for recognizing revenue. The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance will be effective for the Company on January 1, 2017 and may be applied retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is evaluating the potential impact of adopting this new accounting guidance.

In June 2014, the Financial Accounting Standards Board issued a standards update on accounting for share-based payments when the terms of the award provide that a performance target could be achieved after a requisite service period. The standard is effective beginning January 1, 2016, with early adoption permitted. We do not expect it to have a material impact on our consolidated financial position, results of operations or cash flows.

3. Fair Value of Financial Instruments

The Company measures certain financial assets at fair value. Fair value is determined based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants, as determined by either the principal market or the most advantageous market. Inputs used in the valuation techniques to derive fair values are classified based on a three-level hierarchy, as follows:

• Level 1—Quoted prices in active markets for identical assets or liabilities.

• Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities.

• Level 3—Unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities.

The Company considers all highly liquid investments purchased with a remaining maturity of three months or less to be cash equivalents. The fair value of the Company’s investments in certain money market funds is their face value. Such instruments are classified as Level 1 and are included in cash and cash equivalents.

For certain other financial instruments, including accounts receivable, accounts payable and other current liabilities, the carrying amounts approximate their fair value due to the relatively short maturity of these balances.

83

The fair value of these financial assets was determined using the following inputs for the year end December 31, 2014. The Company did not have any cash equivalents at December 31, 2013.

	December 31, 2014
	Level 1		Level 2		Level 3

Accumulated depreciation for equipment under capital lease was $339 thousand as of December 31, 2014, $272 thousand as of December 31, 2013, and $153 thousand as of December 31, 2012

5. Intangible Assets

Intangible assets as of December 31, 2014 and 2013 consist of the following:

	Average Remaining Useful Life		December 31,
			2014			2013

Acquired intellectual property		27 Months		80			—
Accumulated amortization				(736	)		(598	)
Total			$	89		$	147

The estimated useful life of acquired technology and intellectual property is three years. The Company evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets.

Amortization expense related to intangible assets was $138 thousand in 2014, $359 thousand in 2013, and $224 thousand in 2012. Amortization expense of acquired technology is included in cost of subscription revenue

84

in the consolidated statements of operations. Amortization expense of acquired intellectual property is included in sales and marketing expense in the consolidated statements of operations. Estimated future amortization expense for intangible assets as of December 31, 2014 is as follows:

6. Debt

Equipment Line—In June 2010, the Company executed a loan and security agreement (the “Loan Agreement”) establishing a $500,000 equipment line of credit (the “Equipment Line”) with a bank for eligible equipment purchases through June 28, 2011. Borrowings under the Line were due in 24 equal monthly payments of principal, plus accrued interest, at an annual rate of 3.25% beginning July 1, 2011 through June 1, 2013. Borrowings were collateralized by the equipment, software and other property financed by the Loan Agreement. The Company was required to maintain certain non-financial covenants. The Equipment Line expired on June 1, 2013 and was not renewed.

Growth Capital and Revolving Line—In April 2012, the Company amended and restated the Loan Agreement. The Company could borrow up to $5.0 million on a growth capital line of credit (“Growth Capital Line”) through April 2013, at the bank’s prime rate plus one percent. The Growth Capital Line was repayable beginning May 2013 in monthly installments of principal and interest through October 2015. The Company could borrow up to $5.0 million on a revolving line of credit (“Revolving Line”) at the bank’s prime rate, which was payable in full in October 2013. Both lines were established to provide financing for general corporate purposes. The Company was required to maintain a minimum cash account balance of $1.0 million and all of the Company’s assets, excluding intellectual property, was pledged as collateral.

As part of the amended and restated Loan Agreement, the Company issued the bank a fully exercisable warrant to purchase 13,158 shares of common stock at an exercise price of $5.70 per share with an expiration date of April 2022. The fair value of the warrant of $50 thousand was recorded as interest expense in 2012 as it was issued fully vested. The fair value of the warrant was estimated on the date of the grant using the Black-Scholes option-pricing model with the following assumptions:

Risk-free interest rate	2.25	%
Expected term (in years)	10
Volatility	55	%
Expected dividends	—	%

In May 2013, the Company executed the first amendment to the amended and restated Loan Agreement. The Growth Capital Line was extended through May 2014 and was repayable beginning June 2014 in monthly installments of principal and interest through November 2016. The Revolving Line was extended through May 2014.

In September 2013, the Company executed the second amendment to the amended and restated Loan Agreement, increasing the Revolving Line to $20.0 million and extending the maturity date to December 31, 2014. A 0.25% annual unused facility fee is applicable to the Revolving Line.

85

In March 2014, the Company executed the third amendment to the amended and restated Loan Agreement. The Growth Capital Line was extended with borrowings available through December 2014 and repayable over 30 months through June 2017. Additionally, the Revolving Line was increased to $30.0 million and is payable in full in March 2016.

In September 2014, the Company amended its Loan Agreement to combine its $5.0 million Growth Capital Line and $30.0 million Revolving Line into a single $35.0 million Revolving Line. The interest rate on the new Revolving Line is the bank’s prime rate plus 0.5% and is due in full in March 2016. During 2014 the Company drew down $18 million under the Revolving line. In October 2014, in connection with the Company’s IPO, the Company paid off the $18.0 million outstanding balance under the Revolving Line and there is no outstanding balance under the Revolving Line at December 31, 2014.

8. Commitments and Contingencies

The Company leases its office facilities under non-cancelable operating leases that expire at various dates through November 2020. Rent expense for non-cancellable operating leases with free rental periods or scheduled rent increases is recognized on a straight-line basis over the terms of the leases. Improvement reimbursements from landlords of $3.3 million are being amortized on a straight-line basis into rent expense over the terms of the leases. The difference between required lease payments and rent expense has been recorded as deferred rent.

Rent expense was $4.9 million in 2014, $3.1 million in 2013, and $1.3 million in 2012. Deferred rent was $4.3 million as of December 31, 2014 and $2.5 million as of December 31, 2013.

86

In August 2011, the Company sublet a portion of its office space to an unrelated third party and entered into a sublease that expired in January 2014. Sublease income was $11 thousand in 2014, $135 thousand in 2013, and $130 thousand in 2012.

In October 2013, the Company extended a lease agreement for the purchase of equipment with a fair value of $299 thousand. The lease is payable in 36 monthly payments through September 2016. The total outstanding balance financed under capital leases was $178 thousand as of December 31, 2014, $299 thousand as of December 31, 2013. Amortization of assets recorded under capital leases is included in depreciation expense.

Future minimum payments under all operating and capital lease agreements as of December 31, 2014, are as follows:

On November 13, 2013, a putative class action complaint was filed in the Middlesex County Superior Court in the Commonwealth of Massachusetts, entitled Albert McCormack v. HubSpot, Inc. The complaint alleged that the Company maintained a policy of not paying overtime to its business development representatives for all hours worked in excess of 40 hours per week. The complaint sought unpaid wages, multiple damages, injunctive relief, attorneys’ fees and costs. The Company settled this matter for an immaterial amount and the complaint was dismissed on November 3, 2014.

In addition, from time to time the Company may become involved in legal proceedings or be subject to claims arising in the ordinary course of its business. Although the results of litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of these ordinary course matters will not have a material adverse effect on its business, operating results, financial condition or cash flows. Regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources and other factors.

10. Reverse Stock Split

On September 25, 2014, the Company’s Board of Directors and stockholders approved a 1-for-3 reverse stock split of the Company’s common stock. The reverse stock split became effective on September 25, 2014. Upon the effectiveness of the reverse stock split, (i) every three shares of outstanding common stock was combined into one share of common stock, (ii) the number of shares of common stock into which each outstanding warrant or option to purchase common stock is exercisable was proportionally decreased, (iii) the exercise price of each outstanding warrant or option to purchase common stock was proportionately increased, and (iv) the conversion ratio for each share of preferred stock outstanding was proportionately reduced. Unless otherwise indicated, all of the share numbers, share prices and exercise prices in these consolidated financial statements have been adjusted, on a retroactive basis, to reflect this 1-for-3 reverse stock split.

11. Redeemable Convertible Preferred Stock

Upon the closing of the IPO on October 15, 2014, all outstanding convertible preferred stock was converted into 19,529,713 shares of common stock on a one-to-three basis. No convertible preferred stock was outstanding as of December 31, 2014.

Prior to the IPO, the Company had authorized and issued Series A redeemable convertible preferred stock (“Series A”), Series B redeemable convertible preferred stock (“Series B”), Series C redeemable convertible preferred stock (“Series C”), Series D redeemable convertible preferred stock (“Series D”), Series D-1, and Series E redeemable convertible preferred stock (“Series E”) (collectively, “Preferred Stock”); which was classified as temporary equity.

The rights and privileges of Series A, Series B, Series C, Series D, Series D-1 and Series E (collectively, the “Preferred Stock”) were as follows:

Voting Rights—The holders of the Preferred Stock were entitled to vote on all matters and had the number of votes equal to the number of shares of common stock into which the Preferred Stock were then convertible.

Dividends—The holder of shares of Preferred Stock were entitled to receive dividends, when and if declared by the Company’s Board of Directors, out of any assets at the time legally available therefore, in preference to common stockholders. No dividends on convertible preferred stock were declared or paid by the Company through the date of the IPO.

88

Conversion—Prior to the IPO, each share of Preferred Stock was convertible at any time, at the option of the holder into shares of common stock, subject to the applicable conversion rate as determined by dividing the original issue price by the conversion price, with the exception of Series D-1. The issuance price was approximately $0.41 for Series A, $0.84 for Series B, $1.27 for Series C, $2.82 for Series D and $5.62 for Series E. The initial conversion prices were the same as the issuance prices and were adjusted to give effect to the Stock Split. Each share of Series D-1 could be converted as determined by dividing the Series D issuance price by the Series D conversion price (as adjusted for certain dilutive events).

Each share of Preferred Stock automatically converted into shares of common stock at the then-effective conversion rate on the date of the Company’s IPO.

Liquidation Preference—Prior to the IPO, the holders of the Preferred Stock had preferences over the holders of the Company’s common stock in the event of any voluntary or involuntary liquidation, dissolution, or winding-up of the Company, including a merger or consolidation. The amount that would have been paid per share was equal to the greater of approximately $0.41 for Series A, $0.84 for Series B, $1.27 for Series C, $2.82 for Series D, $1.77 for Series D-1 and $5.62 for Series E (as adjusted for certain dilutive events) plus any declared and unpaid dividends or such amount per share as would have been payable had all shares of the Preferred Stock been converted to common stock immediately prior to the liquidation event. Thereafter, any remaining assets available for distribution would have been distributed among the common stockholders.

Redemption—Prior to the IPO, upon written notice of 65% of the holders of Preferred Stock, the Preferred Stock was redeemable in three annual installments commencing 30 days after receipt by the Company at any time on or after March 3, 2020 for all series, except Series E. Series E was redeemable in one installment commencing 30 days after receipt by the Company at any time on or after March 3, 2020. The redemption price per share was approximately $0.41 for Series A, $0.84 for Series B, $1.27 for Series C, $2.82 for Series D, $1.77 for Series D-1 and $5.62 for Series E, plus any declared and unpaid dividends.

The Company was accreting Series A, Series B, Series C, Series D and Series E to their redemption value over the period from the date of issuance to March 3, 2020, such that the carrying amounts of the securities would equal the redemption amounts at the earliest redemption date. Upon the closing of the Company’s IPO all outstanding shares of preferred stock were accreted to their redemption value.

The following table contains the value of each class of Preferred Stock as of December 31, 2013, as well as the liquidation and redemption value at December 31, 2013:

	December 31, 2013
	(in thousands)
Series A designated, issued, and outstanding, 13,687 shares at December 31, 2013 (liquidation and redemption value of $5,625 at December 31, 2013)	$	5,528

Equity Incentive Plan—The Company’s 2007 Equity Incentive Plan (the “2007 Plan”) was terminated in connection with the IPO, and accordingly, no shares are available for issuance under the 2007 Plan. The 2007 Plan will continue to govern outstanding awards granted thereunder, The 2007 Plan provided for the grant of qualified incentive stock options and nonqualified stock options or other awards such as RSUs to the Company’s employees, officers, directors and outside consultants. As of December 31, 2014, 4.4 million options to purchase common stock and 1.3 million RSUs remained outstanding under the 2007 Plan.

On September 25, 2014, the Company’s board of directors adopted and the Company’s stockholders approved the 2014 Stock Option and Incentive Plan (the “2014 Plan”). The 2014 Plan became effective upon the closing of the Company’s IPO. The Company initially reserved 1,973,551 shares of its common stock, or the Initial Limit, for the issuance of awards under the 2014 Plan. The 2014 Plan provides that the number of shares reserved and available for issuance under the plan automatically increases each January 1, beginning on January 1, 2015, by 5% of the outstanding number of shares of the Company’s common stock on the immediately preceding December 31 or such lesser number of shares as determined by the compensation committee. This number is subject to adjustment in the event of a stock split, stock dividend or other change in the Company’s capitalization. As of December 31, 2014, 140 thousand options to purchase common stock and 35 thousand RSUs remained outstanding under the 2014 Plan.

Equity Compensation Expense—The Company’s equity compensation expense is comprised of awards of options to purchase common stock, restricted stock awards (RSAs) and RSUs.

The following two tables show stock compensation expense by award type and where the stock compensation expense is recorded in the Company’s consolidated statements of operations (in thousands):

Excluded from stock-based compensation expense is $235 thousand of capitalized software development costs in 2014, $273 thousand in 2013, and $100 thousand in 2012.

Stock Options—The fair value of employee options is estimated on the date of each grant using the Black-Scholes option-pricing model with the following assumptions:

	Year Ended December 31,
	2014	2013	2012
Risk-free interest rate	1.79% - 2.67%	0.82% - 1.86%	0.56% - 1.23%
Expected term (in years)	5.0 - 6.5	4.6 - 6.5	3.5 - 6.5
Volatility	44.8% - 50.9%	46.8% - 54.7%	48% - 51%
Expected dividends	—	—	—

The weighted-average grant-date fair value of options granted was $9.72 per share in 2014, $6.84 per share in 2013, and $3.09 per share in 2012.

The interest rate was based on the U.S. Treasury bond rate at the date of grant with a maturity approximately equal to the expected term. The expected term of options granted to employees was calculated using the simplified method, which represents the average of the contractual term of the option and the weighted-average vesting period of the option. The expected term of options granted to nonemployees is equal to the remaining contractual term as of the measurement date. Expected volatility for the Company’s common stock was based on an average of the historical volatility of a peer group of similar public companies. The assumed dividend yield is based upon the Company’s expectation of not paying dividends in the foreseeable future. The estimation of share-based awards that will ultimately vest requires judgment, and to the extent actual results differ from the Company’s estimates, such amounts will be recorded as an adjustment in the period estimates are revised.

Prior to the Company’s IPO, the fair value of the common stock was determined by the Board of Directors at each award grant date based upon a variety of factors, including the results obtained from independent third-party valuations, the Company’s financial position and historical financial performance, the status of technological developments within the Company’s products, the composition and ability of the engineering and management team, an evaluation of benchmark of the Company’s competition, the climate in the marketplace, the illiquid nature of the common stock, arm’s-length sales of the Company’s capital stock (including redeemable convertible preferred stock), the effect of the rights and preferences of the preferred stockholders and the prospects of a liquidity event, among others. After the Company’s IPO, the fair value of the Company’s common stock is the closing price of the stock on the date of grant.

The stock option activity for the year ended December 31, 2014 is as follows:

	Options (in thousands)			Weighted- Average Exercise Price		Weighted- Average Remaining Life (in years)		Aggregate Intrinsic Value (in thousands)
Outstanding—December 31, 2013		4,695		$	6.66		8.0	$	37,651
Granted		1,067			19.39
Exercised		(850	)		4.46
Forfeited/expired		(324	)		12.10
Outstanding—December 31, 2014		4,588			9.64		7.6	$	110,396
Options vested or expected to vest—December 31, 2014		4,296		$	9.14		7.5	$	105,418
Options exercisable—December 31, 2014		2,438		$	5.90		6.8	$	67,557

Total unrecognized compensation cost related to the nonvested options granted under the 2007 Plan and the 2014 Plan was $10.4 million at December 31, 2014. That cost is expected to be recognized over a weighted-average period of 2.8 years as of December 31, 2014.

Common Stock Warrant—In 2012, in conjunction with the revolving and term loan agreement (see Note 6), the Company issued a warrant to purchase 13 thousand shares of common stock at an exercise price of $5.70 per share with an expiration date of April 2022. The warrant is exercisable and outstanding at December 31, 2013 and December 31, 2014.

Restricted Stock Awards—In June 2011, in connection with the Performable acquisition, the Company issued 220 thousand shares of restricted common stock to former Performable employees. These shares were subject to repurchase agreements and if the holder ceased to have a business relationship with the Company, the Company could repurchase any unvested shares of common stock held by these individuals at prices that ranged from $0.00143 to $0.855 per share. These shares were issued for no consideration and therefore the fair value of these shares of $1.2 million was recorded as compensation expense over the vesting period. As of December 31, 2013 the Company’s right to repurchase the RSAs had fully lapsed.

During 2012, the Company reclassified $2 thousand into stockholder’s deficit representing the amounts no longer subject to repurchase for 90 thousand shares that vested during the year. During 2013, the Company reclassified $2 thousand into stockholder’s deficit representing the amounts no longer subject to repurchase for 67 thousand shares that vested during the year.

The activity for the RSAs for the year ended December 31, 2013, is as follows:

	Restricted Shares (in thousands)			Weighted- Average Grant-Date Fair Value
Outstanding—January 1, 2013		67		$	5.70
Lapse in Company buyback right		(67	)	$	5.70
Outstanding—December 31, 2013		—

Restricted Stock Units—RSUs vest upon achievement of a service condition and a performance condition. As soon as practicable following each vesting date, the Company will issue to the holder of the RSUs the number of shares of common stock equal to the aggregate number of RSUs that have vested. Notwithstanding the foregoing, the Company may, in its sole discretion, in lieu of issuing shares of common stock to the holder of the RSUs, pay the holder an amount in cash equal to the fair market value of such shares of common stock. The

92

service condition is a time-based condition met over a period of four years, with 25% met after one year, and then in equal monthly installments over the succeeding three years. The performance condition is met upon a sale event or six months following the Company’s IPO, which was not considered probable as of December 31, 2013 and therefore no stock-based compensation expense was recorded in the consolidated financial statements as of that date. Upon completion of the Company’s IPO the Company began recording stock-based compensation expense based on the grant-date fair value of the RSUs using the accelerated attribution method for RSUs granted prior to its IPO and using the straight-line method for RSUs granted following its IPO, net of estimated forfeitures. The stock compensation expense associated with RSUs where the service condition had been met prior to the IPO was also recognized on the date of the IPO, using the accelerated attribution method. The total stock-based compensation expense expected to be recorded over the remaining life of outstanding RSUs is approximately $10.5 million at December 31, 2014. That cost is expected to be recognized over a weighted-average period of 3.3 years as of December 31, 2014. As of December 31, 2014 there are 905 thousand RSUs expected to vest with an aggregate intrinsic value of $30.4 million.

The following table summarizes the activity related to RSUs for the year ended December 31, 2014:

	RSUs Outstanding
	Shares (in thousands)			Weighted-Average Grant Date Fair Value Per Share
Unvested and outstanding at December 31, 2013		858		$	13.29
Granted		784		$	20.55
Vested		—		$	—
Canceled		(266	)	$	13.42
Unvested and outstanding at December 31, 2014		1,376		$	17.40

13. Employee Stock Purchase Plan

On September 25, 2014, the Company’s board of directors adopted and the Company’s stockholders approved the 2014 Employee Share Purchase Plan (the “2014 ESPP”). The 2014 ESPP became effective upon the closing of the Company’s IPO. The 2014 ESPP authorizes the issuance of up to a total of 394,710 shares of common stock to participating employees, and allows eligible employees to purchase shares of common stock at a 15% discount from the fair market value of the stock as determined on specific dates at six-month intervals. The offering periods generally start on the first trading day on or after January 1^st and July 1^st of each year.

14. Income Taxes

Loss before provision for income taxes was as follows:

	Year Ended December 31,
	2014			2013			2012
	(in thousands)
United States	$	(49,634	)	$	(34,393	)	$	(18,358	)

The following reconciles the differences between income taxes computed at the federal statutory rate of 35% and the provision for income taxes:

	Year Ended December 31,
	2014			2013			2012
	(in thousands)
Expected income tax benefit at the federal statutory rate	$	16,913		$	11,997		$	6,572
State tax net of federal benefit		1,709			1,197			653
Stock-based compensation		(886	)		(830	)		(462	)
Difference in foreign tax rates		289			27			(95	)
Research and development credits		1,331			444			140
Valuation allowance for deferred tax assets		(16,839	)		(12,367	)		(6,959	)
Expired state net operating losses		(1,880	)		—			—
Other		(545	)		(468	)		151
Income tax benefit	$	92		$	—		$	—

In 2014, the Company had a current state and foreign income tax expense of $(20) thousand and $(12) thousand, respectively, and a deferred foreign income tax benefit of $124 thousand.

Deferred Tax Assets and Liabilities—Deferred income taxes reflect the net 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 were as follows:

	Year Ended December 31,
	2014			2013			2012
	(in thousands)
Deferred tax assets:
Net operating loss carryforwards	$	46,615		$	35,077		$	23,810
Research and investment credits		2,334			986			541
Accruals and reserves		3,423			2,430			2,025
Depreciation		372			172			202
Stock-based compensation		5,409			395			124
Total deferred tax assets	$	58,153		$	39,060		$	26,702
Deferred tax liabilities:
Intangible and prepaid assets		(2,367	)		(57	)		(123	)
Capitalized costs		(441	)		(620	)		(563	)
Total deferred tax liabilities		(2,808	)		(677	)		(686	)
Valuation allowance		(55,221	)		(38,383	)		(26,016	)
Net deferred tax assets	$	124		$	—		$	—

The Company reviews all available evidence to evaluate its recovery of deferred tax assets, including its recent history of accumulated losses in all tax jurisdictions over the most recent three years as well as its ability to generate income in future periods. The Company has provided a valuation allowance against its U.S. net deferred tax assets as it is more likely than not that these assets will not be realized given the nature of the assets and the likelihood of future utilization.

The valuation allowance increased by $16.8 million in 2014, $12.4 million in 2013, and $7.0 million in 2012 due to the increase in the deferred tax assets by approximately the same amounts (primarily due to the increase in the net operating loss carryforwards).

94

U.S. income taxes on the undistributed earnings of the Company’s two non-U.S. subsidiaries have not been provided for as the Company currently plans to indefinitely reinvest these amounts and has the ability to do so. Cumulative undistributed foreign earnings were not material at December 31, 2014 and December 31, 2013. The Company does not believe it is practicable to estimate with reasonable accuracy the hypothetical amount of the unrecognized deferred tax liability on undistributed foreign earnings given the many factors and assumptions required to estimate the taxable amount after reduction for available foreign tax credits.

The Company had federal and state net operating loss carryforwards of $124.3 million and $79.7 million, respectively at December 31, 2014, which expire at various dates through 2034. The Company has generated net operating loss carryforwards from stock compensation deductions and the amount of federal and state excess tax benefits totaling $1.5 million will be credited to additional paid-in capital when realized.

The Company had federal research and development credit carryforwards of $2.7 million at December 31, 2014 that expire at various dates through 2034. The Company also has state research and investment credit carryforwards of $1.7 million and $320 thousand, respectively that expire at various dates through 2034.

On December 19, 2014 the Tax Increase Prevention Act was signed into law. The Act contains provisions that extended the federal research credit through the end of 2014. The federal research credit provisions had previously expired at the end of 2013. A benefit of $839 thousand for 2014 federal research credit is reflected in the financial statements.

Uncertain Tax Positions—The Company accounts for uncertainty in income taxes using a two-step process. The Company first determines whether it is more likely than not that a tax position will be sustained upon examination by the tax authority, including resolutions of any related appeals or litigation processes, based on technical merit. If a tax position meets the more-likely-than-not recognition threshold it is then measured to determine the amount of benefit to recognize in the financial statements. The tax position is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement.

The following summarizes activity related to unrecognized tax benefits:

	Year Ended December 31,
	2014		2013		2012
	(in thousands)
Unrecognized benefit—beginning of the year	$	1,030	$	667	$	552
Gross increases—current period positions		683		363		115
Unrecognized benefit—end of period	$	1,713	$	1,030	$	667

All of the unrecognized tax benefits decrease deferred tax assets with a corresponding decrease to the valuation allowance. None of the unrecognized tax benefits would affect the Company’s effective tax rate if recognized in the future.

The Company has elected to recognize interest and penalties related to uncertain tax positions as a component of income tax expense. No interest or penalties have been recorded through December 31, 2014.

The Company does not expect any significant change in its unrecognized tax benefits within the next 12 months.

The Company files tax returns in the United States, Ireland, Australia, and various state jurisdictions. All of the Company’s tax years remain open to examination by major taxing jurisdictions to which the Company is subject, as carryforward attributes generated in past years may still be adjusted upon examination by the Internal

95

Revenue Service or state and foreign tax authorities if they have or will be used in future periods. The Company is routinely examined by various taxing authorities. The Company does not expect that the results of ongoing examinations will have a material effect on its financial condition or results of operations.

15. Employee Benefit Plan

In July 2008, the Company established a defined contribution savings plan under Section 401(k) of the Internal Revenue Code. This plan covers substantially all employees who meet minimum age and service requirements and allows participants to defer a portion of their annual compensation on a pretax basis, subject to legal limitations. Fiscal year 2013 was the first year the Company made matching contributions to the 401(k) Plan. Total contributions were $549 thousand in 2014 and $366 thousand in 2013.

None.

ITEM 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a- 15(e) and 15d- 15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act), as of the end of the period covered by this Annual Report on Form 10-K. Based on such evaluation, our principal executive officer and principal financial officer have concluded that as of such date, our disclosure controls and procedures were effective.

Management’s Report on Internal Control Over Financial Reporting

This Annual Report on Form 10-K does not include a report of management’s assessment regarding internal control over financial reporting or an attestation report of the Company’s registered public accounting firm due to a transition period established by rules of the Securities and Exchange Commission for newly public companies.

Inherent Limitations of Internal Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during our most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Our board of directors is divided into three staggered classes of directors. At each annual meeting of stockholders, a class of directors is elected for a three-year term to succeed the same class of directors whose terms are then expiring. The terms of the directors expire upon the election and qualification of successor directors at the annual meeting of stockholders to be held during 2015 for the Class I directors, 2016 for the Class II directors and 2017 for the Class III directors.

• Our Class I directors are Messrs. Halligan, Gill and Bohn.

• Our Class II directors are Ms. Norrington and Messrs. Shah and Skok.

• Our Class III directors are Ms. Bishop and Mr. Simon.

The division of our board of directors into three classes with staggered three-year terms may delay or prevent a change of our management or a change of control. See the section of this Annual Report on Form 10-K captioned “Description of Capital Stock—Anti-Takeover Effects of Delaware Law and Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws” for a discussion of other anti-takeover provisions found in our certificate of incorporation and bylaws.

Director Independence

Under the rules of the New York Stock Exchange, or NYSE, independent directors must comprise a majority of a listed company’s board of directors within a specified period of the completion of its offering. In addition, the rules of NYSE require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent. Under the rules of NYSE, a director will only qualify as an “independent director” if, in the opinion of that company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended. In order to be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors or any other board committee: (1) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries or (2) be an affiliated person of the listed company or any of its subsidiaries.

On January 22, 2015, our board of directors undertook a review of its composition, the composition of its committees and the independence of each director. Based upon information requested from and provided by each director concerning his background, employment and affiliations, our board of directors has determined that, none of the members of the board of directors, except for Messrs. Halligan and Shah, has 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 rules of NYSE. Our board of directors also determined that Ms. Bishop and Messrs. Gill and Skok, who comprise our audit committee, Messrs. Bohn, Simon and Skok, who comprise our compensation committee, and Mr. Bohn and Mses. Bishop and Norrington, who comprise our corporate governance and nominating committee, satisfy the independence standards for those committees established by applicable SEC rules and the rules of NYSE. In making this

101

determination, our board of directors considered the 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.

Board Leadership Structure and Role of the Board in Risk Oversight

Mr. Halligan serves as our chief executive officer and as chairman of the board. The board of directors believes that having our chief executive officer as chairman of the board facilitates the board of directors’decision-making process because Mr. Halligan has first-hand knowledge of our operations and the major issues facing us. This also enables Mr. Halligan to act as the key link between the board of directors and other members of management.

Our board of directors has appointed Ms. Norrington to serve as our lead independent director. As lead independent director, Ms. Norrington presides over periodic meetings of our independent directors, serves as a liaison between our chairman of the board of directors and the independent directors and performs such additional duties as our board of directors may otherwise determine and delegate.

One of the key functions of our board of directors is informed oversight of our risk management process. Our board of directors does not have a standing risk management committee, but rather administers this oversight function directly through the board of directors as a whole, as well as through its standing committees that address risks inherent in their respective areas of oversight. In particular, our board of directors is responsible for monitoring and assessing strategic risk exposure. Our audit committee is responsible for reviewing and discussing our major financial risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies with respect to risk assessment and risk management. Our audit committee also monitors compliance with legal and regulatory requirements, in addition to oversight of the performance of our external audit function. Our corporate governance and nominating committee monitors the effectiveness of our corporate governance guidelines. Our compensation committee reviews and discusses the risks arising from our compensation philosophy and practices applicable to all employees that are reasonably likely to have a materially adverse effect on us.

Board Committees

Our board of directors has an audit committee, a compensation committee and a corporate governance and nominating committee, each of which has the composition and responsibilities described below. The audit committee, compensation committee and corporate governance and nominating committee all operate under charters approved by our board of directors, which are available on our website.

Audit committee

Our audit committee oversees our corporate accounting and financial reporting process and assists the board of directors in monitoring our financial systems and our legal and regulatory compliance. Our audit committee will also:

• oversee the work of our independent registered public accounting firm;

• approve the hiring, discharging and compensation of our independent registered public accounting firm;

• approve engagements of the independent registered public accounting firm to render any audit or permissible non-audit services;

• review the qualifications and independence of the independent registered public accounting firm;

• monitor the rotation of partners of the independent registered public accounting firm on our engagement team as required by law;

102

• review our consolidated financial statements and review our critical accounting policies and estimates;

• review the adequacy and effectiveness of our internal controls; and

• review and discuss with management and the independent registered public accounting firm the results of our annual audit and our interim consolidated financial statements.

The members of our audit committee are Ms. Bishop and Messrs. Gill and Skok. Mr. Gill is our audit committee chairman. Our board of directors has concluded that the composition of our audit committee meets the requirements for independence under, and the functioning of our audit committee complies with, the current requirements of and SEC rules and regulations, and Mr. Gill is an audit committee financial expert as defined under SEC rules and regulations.

Compensation committee

Our compensation committee oversees our corporate compensation programs. The compensation committee will also:

• review and approve corporate goals and objectives relevant to compensation of our chief executive officer and other executive officers;

• evaluate the performance of our executive officers in light of established goals and objectives;

• review and recommend compensation of our executive officers based on its evaluations;

• review and recommend compensation of our directors; and

• administer the issuance of stock options and other awards under our stock plans.

The members of our compensation committee are Messrs. Bohn, Simon and Skok. Mr. Simon is the chairman of our compensation committee. Our board of directors has determined that each of Messrs. Bohn, Simon and Skok is “independent” for compensation committee purposes as that term is defined under the applicable rules.

Nominating and corporate governance committee

Our corporate governance and nominating committee oversees and assists our board of directors in reviewing and recommending corporate governance policies and nominees for election to our board of directors. The corporate governance and nominating committee also:

• evaluates and makes recommendations regarding the organization and governance of the board of directors and its committees;

• assesses the performance of members of the board of directors and makes recommendations regarding committee and chair assignments;

• reviews and makes recommendations with regard to our corporate succession plans for our chief executive officer and other executive officers;

• recommends desired qualifications for board of directors membership and conducts searches for potential members of the board of directors; and

• reviews and makes recommendations with regard to our corporate governance guidelines.

The members of our corporate governance and nominating committee are Mr. Bohn and Mses. Bishop and Norrington. Ms. Norrington is the chairman of our corporate governance and nominating committee. Our board of directors has determined that each member of our corporate governance and nominating committee is independent under the applicable rules of NYSE.

103

Our board of directors may from time to time establish other committees.

Director Compensation

The following table presents the total compensation for each person who served as a non-employee member of our board of directors during 2014. Other than as set forth in the table and described more fully below, we did not pay any compensation, make any equity awards or non-equity awards to, or pay any other compensation to any of the non-employee members of our board of directors in 2014. Mr. Halligan and Mr. Shah, who are also our chief executive officer and chief technology officer, respectively, receive no compensation for their services as directors and, consequently, are not included in this table. The compensation received by Mr. Halligan during 2014 is set forth in the section of this Annual Report on Form 10-K captioned “Executive Compensation— Summary Compensation Table.”

Name	Option Awards(1)		Stock Awards(2)		Total
Ron Gill	$	31,631	$	100,005	$	131,636
Michael Simon	$	31,631	$	100,005	$	131,636

(1) Our board of directors granted these awards in June 2014. The amount reported represents the aggregate grant date fair value of the stock options, calculated in accordance with FASB ASC Topic 718. Such grant date fair value does not take into account any estimated forfeitures related to service-vesting conditions. The assumptions used in calculating the grant-date fair value are set forth in the notes to our audited consolidated financial statements.

(2) Our board of directors granted these awards in June 2014. The amounts reported represent the aggregate grant-date fair value of the RSUs awarded in 2014, calculated in accordance with ASC Topic 718. Such grant-date fair value does not take into account any estimated forfeitures related to service-vesting conditions. The assumptions used in calculating the grant-date fair value are set forth in the notes to our audited consolidated financial statements.

In 2014 we did not maintain any standard fee arrangements for the non-employee members of our board of directors for their service as a director. We adopted a new non-employee director compensation policy in connection with our IPO. Any director affiliated with an investor in our company that holds one percent or more of our capital stock is not eligible to participate in the non-employee director compensation policy. Pursuant to this policy, each of our non-employee directors receives an annual grant of an option to purchase $35,000 worth of common stock (equal to approximately 870 shares, based on price of $40.22 per share, the last reported sale price of our common stock on the New York Stock Exchange on March 4, 2015) and a RSUs grant for $100,000 worth of common stock (equal to approximately 2,490 shares, based on price of $40.22 per share, the last reported sale price of our common stock on the New York Stock Exchange on March 4, 2015). The options and RSUs vest in full on the first anniversary of the vesting start date. All unvested options or RSUs held by a non-employee director accelerate and immediately vest if the non-employee director is terminated within three months prior to or twelve months following a change of control of our company. The exercise price of the options and RSUs must be greater than or equal to the fair market value of a share of our common stock at the time of grant. Each of these directors also annually receives $25,000 for general availability and participation in meetings and conference calls of our board of directors, to be paid quarterly. Additionally, the audit committee chairperson annually receives $15,000, an audit committee member annually receives $5,000, the compensation committee chairperson annually receives $10,000, a compensation committee member annually receives $4,000, the nominating and corporate governance committee chairperson annually receives $5,000 and a nominating and corporate governance committee member annually receives $3,000.

Our policy has been and will continue to be to reimburse our non-employee directors for their travel, lodging and other reasonable expenses incurred in attending meetings of our board of directors and committees of the board of directors.

104

Directors who are employees do not receive any compensation for their service on our board of directors.

Compensation Committee Interlocks and Insider Participation

During 2014, our compensation committee was comprised of Messrs. Bohn, Simon and Skok.

None of the members of our compensation committee is an officer or employee of our company. 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 October and November 2012, we issued and sold an aggregate of 6,267,336 shares of our Series E preferred stock for an aggregate purchase price of approximately $35,000,000. As part of this offering, we sold an aggregate of 219,623 shares of our Series E preferred stock for an aggregate purchase price of $1,233,446.69 to entities affiliated with Matrix Partners, of which Mr. Skok is a general partner. We also sold an aggregate of 346,459 shares of Series E preferred stock for an aggregate purchase price of $1,945,783.04 to entities affiliated with General Catalyst Partners, of which Mr. Bohn is a general partner. We also sold an aggregate of 44,514 shares of Series E preferred stock for an aggregate purchase price of $249,999.53 to Mr. Simon.

For more information regarding sales of our preferred stock, see “Certain Relationships and Related Party Transactions—Sales of Preferred Stock.”

Code of Business Conduct and Ethics

We have adopted a code of business conduct and ethics that is applicable to all of our employees, officers and directors including our chief executive officer and senior financial officers, which is available on our website under “Investors—Corporate Governance.”

ITEM 11. Executive Compensation

Executive Compensation Overview

Historically, our executive compensation program has reflected our growth and development-oriented corporate culture. To date, the compensation of Mr. Halligan, our chief executive officer, and the other executive officers identified in the Summary Compensation Table below, whom we refer to as our named executive officers, has consisted of a combination of base salary and long-term incentive compensation in the form of stock options. Our named executive officers and all salaried employees are also eligible to receive health and welfare benefits. We engaged the services of an independent executive compensation consulting firm to review our current compensation plans and procedures and to provide additional information about comparative compensation offered by peer companies, market survey information and information about trends in executive compensation. At a minimum, we expect to review executive compensation annually with input from a compensation consultant. As part of this review process, we expect the board of directors and the compensation committee to apply our values and philosophy, while considering the compensation levels needed to ensure our executive compensation program remains competitive. We will also review whether we are meeting our retention objectives.

105

Summary Compensation Table

The following table presents information regarding the total compensation awarded to, earned by, and paid to our chief executive officer and the two most highly compensated executive officers (other than the chief executive officer) who were serving as executive officers at the end of the last completed fiscal year for services rendered to us in all capacities for the year ended December 31, 2014. Messrs. Halligan, Kinzer and Madeley are the named executive officers for 2014. Mr. Sherman’s compensation for the year ended December 31, 2013 has been included in the table below because he was a named executive officer for 2013.

(1) The amounts reported represent the aggregate grant-date fair value of the restricted stock units or, RSUs awarded in 2014, calculated in accordance with ASC Topic 718. Such grant-date fair value does not take into account any estimated forfeitures related to service-vesting conditions. The assumptions used in calculating the grant-date fair value are set forth in the notes to our audited consolidated financial statements.

(2) The amounts reported represent the aggregate grant-date fair value of the stock options awarded in 2014, calculated in accordance with ASC Topic 718. Such grant-date fair value does not take into account any estimated forfeitures related to service-vesting conditions. The assumptions used in calculating the grant-date fair value are set forth in the notes to our audited consolidated financial statements.

(3) The amounts reported reflect performance-based payments awarded based on the achievement of certain corporate and individual performance goals under our executive bonus plan.

(4) The amounts reported include 401(k) matching contributions, long-term disability insurance premiums and certain relocation benefits.

(5) The amounts reported reflect company-paid relocation expenses.

(6) Mr. Kinzer was granted 100,000 RSUs in connection with his hiring in 2013. The RSUs are subject to the satisfaction of a service condition and a performance condition, both of which must be satisfied before the RSUs are vested and may be settled in shares of our common stock. The service condition is satisfied over a period of four years. The performance condition will be satisfied on the earlier of (i) a sale of our company or (ii) April 9, 2015, in either case, prior to the earlier of (A) the expiration date or (B) the tenth anniversary of the grant date. These performance conditions were not considered probable as of December 31, 2013 and therefore there was no grant-date fair value calculated in accordance with ASC Topic 718. Such grant-date fair value is $1,440,000 assuming that the highest level of performance conditions will be achieved.

(7) Mr. Kinzer was granted 99,999 stock options at an exercise price of $14.40 in connection with his hiring in 2013.

Such grant-date fair value does not take into account any estimated forfeitures related to service-vesting conditions.

Employee Benefit Plans

2014 Stock Option and Incentive Plan

In September 2014, our board of directors, upon the recommendation of the compensation committee of the board of directors, adopted our 2014 Stock Option and Incentive Plan, or the 2014 Plan, which was subsequently approved by our stockholders. The 2014 Plan became effective upon the completion of our IPO. The 2014 Plan replaced the 2007 Equity Incentive Plan, or the 2007 Plan, as our board of directors has determined not to make additional awards under that plan. Our 2014 Plan provides flexibility to our compensation committee to use various equity-based incentive awards as compensation tools to motivate our workforce.

As of December 31, 2014, we have reserved 1,973,551 shares of our common stock, or the Initial Limit, for the issuance of awards under the 2014 Plan. The 2014 Plan provides that the number of shares reserved and available for issuance under the plan automatically increases each January 1, beginning on January 1, 2015, by 5% of the outstanding number of shares of our common stock on the immediately preceding December 31 or such lesser number of shares as determined by our compensation committee, or the Annual Increase. This number is subject to adjustment in the event of a stock split, stock dividend or other change in our capitalization.

107

The shares we issue under the 2014 Plan are authorized but unissued shares or shares that we reacquire. The shares of common stock underlying any awards that are forfeited, cancelled, held back upon exercise or settlement of an award to satisfy the exercise price or tax withholding, reacquired by us prior to vesting, satisfied without any issuance of stock, expire or are otherwise terminated (other than by exercise) under the 2014 Plan and 2007 Plan are added back to the shares of common stock available for issuance under the 2014 Plan.

Stock options and stock appreciation rights with respect to no more than 1,000,000 shares of stock may be granted to any one individual in any one calendar year and the maximum “performance-based award” (as such term is used under Section 162(m) of the Code) payable to any one individual under the 2014 Plan is 1,000,000 shares of stock or $2,000,000 in the case of cash-based awards. The maximum aggregate number of shares that may be issued in the form of incentive stock options shall not exceed the Initial Limit cumulatively increased on January 1, 2015 and on each January 1 thereafter by the lesser of the Annual Increase for such year or 1,000,000 shares of common stock.

The 2014 Plan is administered by our compensation committee. Our compensation committee has full power to select, from among the individuals eligible for awards, the individuals to whom awards will be granted, to make any combination of awards to participants and to determine the specific terms and conditions of each award, subject to the provisions of the 2014 Plan. Persons eligible to participate in the 2014 Plan are those full or part-time officers, employees, non-employee directors and other key persons (including consultants) as selected from time to time by our compensation committee in its discretion.

The 2014 Plan permits the granting of both options to purchase common stock intended to qualify as incentive stock options under Section 422 of the Code and options that do not so qualify. The option exercise price of each option is determined by our compensation committee but may not be less than 100% of the fair market value of our common stock on the date of grant. The term of each option is fixed by our compensation committee and may not exceed 10 years from the date of grant. Our compensation committee determines at what time or times each option may be exercised.

Our compensation committee may award stock appreciation rights subject to such conditions and restrictions as we may determine. Stock appreciation rights entitle the recipient to shares of common stock, or cash, equal to the value of the appreciation in our stock price over the exercise price. The exercise price of each stock appreciation right may not be less than 100% of the fair market value of the common stock on the date of grant.

Our compensation committee may award restricted shares of common stock and RSUs to participants subject to such conditions and restrictions as it may determine. These conditions and restrictions may include the achievement of certain performance goals and/or continued employment with us through a specified vesting period. Our compensation committee may also grant shares of common stock that are free from any restrictions under the 2014 Plan. Unrestricted stock may be granted to participants in recognition of past services or other valid consideration and may be issued in lieu of cash compensation due to such participant.

Our compensation committee may grant performance share awards to participants that entitle the recipient to receive shares of common stock upon the achievement of certain performance goals and such other conditions as our compensation committee shall determine. Our compensation committee may grant cash bonuses under the 2014 Plan to participants, subject to the achievement of certain performance goals.

Our compensation committee may grant awards of restricted stock, RSUs, performance shares or cash-based awards under the 2014 Plan that are intended to qualify as “performance-based compensation” under Section 162(m) of the Code. Those awards would only vest or become payable upon the attainment of performance goals that are established by our compensation committee and related to one or more performance criteria. The performance criteria that would be used with respect to any such awards include: earnings before interest, taxes, depreciation and amortization, net income (loss) (either before or after interest, taxes, depreciation

108

and/or amortization), changes in the market price of our common stock, economic value-added, funds from operations or similar measure, sales or revenue, acquisitions or strategic transactions, operating income (loss), cash flow (including, but not limited to, operating cash flow and free cash flow), return on capital, assets, equity, or investment, stockholder returns, return on sales, gross or net profit levels, productivity, expense, margins, operating efficiency, customer satisfaction, working capital, earnings (loss) per share of stock, sales or market shares and number of customers, any of which may be measured either in absolute terms or as compared to any incremental increase or as compared to results of a peer group.

The 2014 Plan provides that in the case of, and subject to, the consummation of a “sale event” as defined in the 2014 Plan, all outstanding awards may be assumed, substituted or otherwise continued by the successor entity. Pursuant to the forms of option agreement, restricted stock agreement and restricted stock unit agreement, under the 2014 Plan, in the case of a sale event in which outstanding awards are assumed, substituted or otherwise continued by a successor entity, and the award holder’s employment or service relationship with us terminates, such holder’s awards shall vest in full as of the date of termination if such termination occurs (i) within 12 months after such sale event or 90 days prior to such sale event and (ii) such termination is by us without “cause,” as defined in the applicable award agreement, or by the award holder for “good reason” (as defined in the applicable award agreement). To the extent that the successor entity does not assume, substitute or otherwise continue such awards, then (i) all stock options and stock appreciation rights will automatically become fully exercisable and the restrictions and conditions on all other awards with time-based conditions will automatically be deemed waived, and awards with conditions and restrictions relating to the attainment of performance goals may become vested and non-forfeitable in connection with a sale event in the compensation committee’s discretion and (ii) upon the effectiveness of the sale event, all stock options and stock appreciation rights will automatically terminate. In the event of such termination, individuals holding options and stock appreciation rights will be permitted to exercise such options and stock appreciation rights prior to the sale event. In addition, in connection with a sale event, we may make or provide for a cash payment to participants holding options and stock appreciation rights equal to the difference between the per share cash consideration payable to stockholders in the sale event and the exercise price of the options or stock appreciation rights.

Our board of directors may amend or discontinue the 2014 Plan and our compensation committee may amend or cancel outstanding awards for purposes of satisfying changes in law or for any other lawful purpose, but no such action may adversely affect rights under an award without the holder’s consent. Certain amendments to the 2014 Plan require the approval of our stockholders.

No awards may be granted under the 2014 Plan after the date that is 10 years from the date of stockholder approval. No awards under the 2014 Plan have been made prior to the date hereof.

2007 Equity Incentive Plan

Our 2007 Plan was approved by our board of directors and our stockholders on June 9, 2007 and was most recently amended in February 2014. As of December 31, 2014, we have authorized an aggregate of 8,612,809 shares of our common stock for the issuance of options and other equity awards under the 2007 Plan. This number is subject to adjustment in the event of a stock split, stock dividend or other change in our capitalization. Effective as of the closing of our IPO, our board of directors determined not to grant any further awards under our 2007 Plan. The shares we issue under the 2007 Plan are authorized but unissued shares or shares we reacquire. Prior to our IPO, the shares of common stock underlying any awards that are forfeited, canceled, reacquired by us prior to vesting, satisfied without the issuance of stock or otherwise terminated (other than by exercise) under the 2007 Plan were added back to the shares of common stock available for issuance under the 2007 Plan. Effective upon the closing of our IPO, such shares are added to the shares of common stock available for issuance under the 2014 Plan.

The 2007 Plan is administered by our compensation committee. The board of directors and the compensation committee have the authority to select the individuals to whom awards will be granted, to make

109

any combination of awards to participants, to accelerate the exercisability or vesting of any award, to provide substitute awards and to determine the specific terms and conditions of each award.

The 2007 Plan permits us to make grants of incentive stock options and non-qualified stock options, restricted stock awards, unrestricted stock awards and other stock-based awards such as RSUs to our officers, employees, directors, consultants and other key persons.

The 2007 Plan permits the granting of (1) options to purchase common stock intended to qualify as incentive stock options under Section 422 of the Code and (2) options that do not so qualify. The option exercise price of each option is determined by our board or directors or our compensation committee but may not be less than 100% of the fair market value of the common stock on the date of grant. In the case of an Incentive Stock Option granted to a participant who, at the time of grant of such option, owns stock representing more than 10% of the voting power of all classes of stock of the Company, then the exercise price may not be less than 110% of the fair market value of the common stock on the date of grant. The term of each option will be fixed by the board of directors or the compensation committee and may not exceed 10 years from the date of grant.

The 2007 Plan provides that upon the occurrence of a change of control, awards may be assumed, substituted for new awards of a successor entity, or otherwise continued or terminated at the effective time of such sale event. Pursuant to the forms of option agreement, restricted stock agreement and restricted stock unit agreement, in each case, under the 2007 Plan, in the case of a sale event in which outstanding awards are assumed, substituted or otherwise continued by a successor entity, and the award holder’s employment or service relationship with us terminates, such holder’s awards shall vest in full as of the date of termination if such termination occurs (i) within 12 months after such sale event or 90 days prior to such sale event and (ii) such termination is by us without “cause,” as defined in the applicable award agreement, or by the award holder for “good reason” (as defined in the applicable award agreement). To the extent that the successor entity does not assume, substitute or otherwise continue such awards, then (i) all stock options and stock appreciation rights will automatically become fully exercisable and the restrictions and conditions on all other awards with time-based conditions will automatically be deemed waived, and awards with conditions and restrictions relating to the attainment of performance goals may become vested and non-forfeitable in connection with a sale event in the compensation committee’s discretion and (ii) upon the effectiveness of the sale event, all stock options and stock appreciation rights will automatically terminate. We may make or provide for cash payment to holders of options equal to the difference between the per share cash consideration in the sale event and the exercise price to the holders of vested and exercisable options. We may make or provide for cash payment to holders of restricted stock and RSUs awards in an amount equal to the product of the per share cash consideration and the number of shares subject to each such award.

Our board of directors may amend, suspend or terminate the 2007 Plan at any time, subject to stockholder approval where such approval is required by applicable law. The board of directors may also amend, modify or terminate any outstanding award, provided that no amendment to an award may materially impair any of the rights of a participant under any awards previously granted without his or her written consent.

Employee Share Purchase Plan

In September 2014 our board of directors adopted and our stockholders approved the ESPP. The ESPP authorizes the issuance of up to a total of 394,710 shares of common stock to participating employees. The ESPP provides that the number of shares reserved and available for issuance under the ESPP shall be cumulatively increased each January 1, beginning on January 1, 2015, by the lesser of 1% percent of the outstanding number of shares of our common stock on the immediately preceding December 31 or such lesser number of shares as determined by our compensation committee. The number of shares reserved and available for issuance under the ESPP is subject to adjustment in the event of a stock split, stock dividend or other change in our capitalization.

All employees who we have employed for at least 30 days and whose customary employment is for more than 20 hours a week are eligible to participate in the ESPP. Any employee who owns 5% or more of the voting power or value of our shares of common stock is not eligible to purchase shares under the ESPP.

110

We will make one or more offerings each year to our employees to purchase shares under the ESPP. The first offering began on January 1, 2015 and will end on the last business day occurring on or before June 30, 2015. Subsequent offerings will commence at such time or times as our board of directors may determine, which we expect to be on each January 1 and July 1 and will continue for six-month periods, referred to as offering periods. Each eligible employee may elect to participate in any offering by submitting an enrollment form at least 15 days before the relevant offering date.

Each employee who is a participant in the ESPP may purchase shares by authorizing payroll deductions of up to 15% of his or her base compensation during an offering period. Unless the participating employee has previously withdrawn from the offering, his or her accumulated payroll deductions will be used to purchase shares of common stock on the last business day of the offering period at a price equal to 85% of the fair market value of the ordinary shares on the first business day or the last business day of the offering period, whichever is lower, provided that no more than 300,000 shares of common stock may be purchased by any one employee during each offering period. Under applicable tax rules, an employee may purchase no more than $25,000 worth of ordinary shares, valued at the start of the purchase period, under the ESPP in any calendar year.

The accumulated payroll deductions of any employee who is not a participant on the last day of an offering period will be refunded. An employee’s rights under the ESPP terminate upon voluntary withdrawal from the plan or when the employee ceases employment with us for any reason.

The ESPP may be terminated or amended by our board of directors at any time. An amendment that increases the number of shares of common stock that are authorized under the ESPP and certain other amendments require the approval of our stockholders.

Senior Executive Cash Incentive Bonus Plan

In August 2014 our board of directors adopted the Senior Executive Cash Incentive Bonus Plan, or the Bonus Plan. The Bonus Plan provides for cash bonus payments based upon the attainment of performance targets established by our compensation committee. The payment targets will be related to financial and operational measures or objectives with respect to our company, which we refer to as corporate performance goals, as well as individual performance objectives.

Our compensation committee may select corporate performance goals from among the following: revenue; expense levels; cash flow (including, but not limited to, operating cash flow and free cash flow); business development and financing milestones; earnings before interest, taxes, depreciation and amortization; net income (loss) (either before or after interest, taxes, depreciation and/or amortization); changes in the market price of our common stock; economic value added; sales; acquisitions or strategic transactions; operating income (loss); return on capital, assets, equity, or investment; shareholder returns; return on sales; gross or net profit levels; productivity; expense; margins; operating efficiency; customer satisfaction; working capital; earnings (loss) per share of our common stock; sales or market shares and total customers; and Adjusted EBITDA, any of which may be measured in absolute terms, as compared to any incremental increase, in terms of growth, or as compared to results of a peer group.

Each executive officer who is selected to participate in the Bonus Plan will have a target bonus opportunity set for each performance period. The bonus formulas will be adopted in each performance period by the compensation committee and communicated to each executive. The corporate performance goals will be measured at the end of each performance period after our financial reports have been published or such other appropriate time as the compensation committee determines. If the corporate performance goals and individual performance objectives are met, payments will be made as soon as practicable following the end of each performance period. Subject to the rights contained in any agreement between the executive officer and us, an executive officer must be employed by us on the bonus payment date to be eligible to receive a bonus payment.

111

The Bonus Plan also permits the compensation committee to approve additional bonuses to executive officers in its sole discretion.

Retirement Plans

We maintain a tax-qualified 401(k) retirement plan for eligible employees in the United States. Under our 401(k) plan, employees may elect to defer up to 96% of their eligible compensation subject to applicable annual limits set pursuant to the Code. We currently provide an employee matching contribution under the 401(k) plan. Employees are 100% vested in their contributions to the 401(k) plan and any employer contributions after one year of service. We intend for the 401(k) plan to qualify, depending on the employee’s election, under Section 401(a) of the Code so that contributions by employees, and income earned on those contributions, are not taxable to employees until withdrawn from the 401(k) plan.

Indemnification of Officers and Directors

We have agreed to indemnify our directors and officers in certain circumstances. See “Certain Relationships and Related Party Transactions—Limitation of Liability and Indemnification of Officers and Directors.”

Compensation Risk Assessment

We believe that although a portion of the compensation provided to our executive officers and other employees is performance-based, our executive compensation program does not encourage excessive or unnecessary risk taking. This is primarily due to the fact that our compensation programs are designed to encourage our executive officers and other employees to remain focused on both short-term and long-term strategic goals, in particular in connection with our pay-for-performance compensation philosophy. As a result, we do not believe that our compensation programs are reasonably likely to have a material adverse effect on us.

ITEM 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters

The following table sets forth information regarding beneficial ownership of our common stock as of December 31, 2014 by:

• each person or group of affiliated persons known by us to be the beneficial owner of more than 5% of our common stock;

• each of our named executive officers;

• each of our directors; and

• all executive officers and directors as a group.

We have determined beneficial ownership in accordance with SEC rules. The information does not necessarily indicate beneficial ownership for any other purpose. Under these rules, the number of shares of common stock deemed outstanding includes shares issuable upon exercise of options and warrants held by the respective person or group which may be exercised or converted within 60 days after December 31, 2014. For purposes of calculating each person’s or group’s percentage ownership, stock options and warrants exercisable within 60 days after December 31, 2014 are included for that person or group but not the stock options or warrants of any other person or group. Certain options to purchase shares of our common stock included in the table below are early exercisable, and to the extent such shares are unvested as of a given date, such shares will remain subject to a right of repurchase held by us.

Applicable percentage ownership is based on 31,430,769 shares of common stock outstanding as of December 31, 2014.

Unless otherwise indicated and subject to applicable community property laws, to our knowledge, each stockholder named in the following table possesses sole voting and investment power over the shares listed. Unless otherwise noted below, the address of each person listed on the table is c/o HubSpot, Inc., 25 First Street, 2nd Floor, Cambridge, Massachusetts 02141.

DESCRIPTION OF CAPITAL STOCK

General

The following description summarizes the most important terms of our capital stock. We adopted an amended and restated certificate of incorporation and amended and restated bylaws in connection with our initial public offering, or IPO, and this description summarizes the provisions 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 “Description of Capital Stock,” you should refer to our amended and restated certificate of incorporation and amended and restated bylaws, which are included as exhibits to the Annual Report on Form 10-K, and to the applicable provisions of Delaware law. Our authorized capital stock consists of 500,000,000 shares of common stock, $0.001 par value per share, and 25,000,000 shares of undesignated preferred stock, $0.001 par value per share.

As of December 31, 2014, there were 31,430,769 shares of our common stock outstanding, held by 455 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 NYSE to issue additional shares of our capital stock.

Common Stock

The holders of our common stock are entitled to one vote per share on all matters to be voted on by our stockholders. Subject to preferences that may be applicable to any outstanding shares of preferred stock, holders of common stock are entitled to receive ratably such dividends as may be declared by our board of directors out of funds legally available for that purpose. In the event of our liquidation, dissolution or winding up, the holders of common stock are entitled to share ratably in all assets remaining after the payment of liabilities, subject to the prior distribution rights of preferred stock then outstanding. Holders of common stock have no preemptive, conversion or subscription rights. There are no redemption or sinking fund provisions applicable to the common stock.

Preferred Stock

Upon the closing of our IPO, all outstanding shares of preferred stock converted into shares of our common stock, and there are no shares of preferred stock outstanding.

Though we currently have no plans to issue any shares of preferred stock, our board of directors has the authority, without further action by our stockholders, to designate and issue up to 25,000,000 shares of preferred stock in one or more series. Our board of directors may also designate the rights, preferences and privileges of the holders of each such series of preferred stock, any or all of which may be greater than or senior to those granted to the holders of common stock. Though the actual effect of any such issuance on the rights of the holders of common stock will not be known until such time as our board of directors determines the specific rights of the holders of preferred stock, the potential effects of such an issuance include:

• diluting the voting power of the holders of common stock;

• reducing the likelihood that holders of common stock will receive dividend payments;

• reducing the likelihood that holders of common stock will receive payments in the event of our liquidation, dissolution, or winding up; and

• delaying, deterring or preventing a change-in-control or other corporate takeover.

Registration Rights

The holders of an aggregate of 20,200,445 shares of our common stock and the holders of warrants to purchase common stock are entitled to the following rights with respect to the registration of such shares for

115

public resale under the Securities Act of 1933, as amended, or the Securities Act, pursuant to a registration rights agreement by and among us and certain of our stockholders. We refer to these shares collectively as “registrable securities.”

The registration of shares of common stock as a result of the following rights being exercised would enable the holders to trade these shares without restriction under the Securities Act when the applicable registration statement is declared effective. Ordinarily, we will be required to pay all expenses, other than underwriting discounts and commissions, related to any registration effected pursuant to the exercise of these registration rights.

Demand Registration Rights

If at any time after April 7, 2015 the holders of at least 25% of the registrable securities then outstanding request in writing that we effect a registration, we may be required to register the offer and sale of their shares anticipated to have an aggregate sale price, net of underwriting discounts and commissions, if any, of $10 million. At most, we are obligated to effect two registrations for the holders of registrable securities in response to these demand registration rights. Depending on certain conditions, however, we may defer such registration for up to 90 days. If the holders requesting registration intend to distribute their shares by means of an underwriting, the managing underwriter of such offering will have the right to limit the number of shares to be underwritten for reasons related to the marketing of the shares.

Piggyback Registration Rights

If we propose to register the offer and sale of any shares of our securities under the Securities Act, the holders of registrable securities will be entitled to notice of the registration and to include their shares of registrable securities in the registration. These piggyback registration rights are subject to certain conditions and limitations, including the right of the underwriters to limit the number of shares included in any such registration under specific circumstances. We have the right to terminate or withdraw any registration initiated by us prior to the effectiveness of such registration whether or not the holders of registrable securities have elected to include their shares in the registration.

Form S-3 Registration Rights

If at any time we become entitled under the Securities Act to register our shares on Form S-3 and the holders of the registrable securities then outstanding request in writing that we register their shares for public resale on Form S-3 with an aggregate price to the public of the shares to be registered of at least $2 million, we will be required to effect such registration; provided, however, that if our board of directors determines, in good faith, that such registration would be materially detrimental to us and our stockholders at such time, we may defer the registration for up to 90 days. We are only obligated to effect up to two registrations on Form S-3 within any twelve month period.

Voting Rights

Under the provisions of our certificate of incorporation, holders of our common stock are entitled to one vote for each share of common stock held by such holder on any matter submitted to a vote at a meeting of stockholders. Our post-offering certificate of incorporation does not provide cumulative voting rights to holders of our common stock.

Anti-Takeover Effects of Delaware Law and Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws

Certain provisions of Delaware law and our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that could have the effect of delaying, deferring or discouraging another party from acquiring control of us. These provisions, which are summarized below, are expected to discourage

116

certain types of coercive takeover practices and inadequate takeover bids. These provisions are also designed in part to encourage anyone seeking to acquire control of us to first negotiate with our board of directors. We believe that the advantages gained by protecting our ability to negotiate with any unsolicited and potentially unfriendly acquirer outweigh the disadvantages of discouraging such proposals, including those priced above the then-current market value of our common stock, because, among other reasons, the negotiation of such proposals could improve their terms.

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

Our amended and restated certificate of incorporation and our amended and 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:

• authorize our board of directors to issue, without further action by the stockholders, up to 25,000,000 shares of undesignated preferred stock;

• specify that special meetings of our stockholders can be called only by our board of directors, the chairman of our board of directors, the chief executive officer or the president;

• establish an advance notice procedure for stockholder proposals to be brought before an annual meeting of our stockholders, including proposed nominations of persons for election to our board of directors;

• provide that directors may be removed only for cause;

• provide that vacancies on our board of directors may be filled only by a majority of directors then in office, even though less than a quorum;

• establish that our board of directors is divided into three classes—Class I, Class II and Class III—with each class serving staggered terms; and

• require a super-majority of votes to amend certain of the above-mentioned provisions.

Delaware Anti-Takeover Statute

We are subject to the provisions of Section 203 of the General Corporation Law of the State of Delaware regulating corporate takeovers. In general, Section 203 prohibits a publicly-held Delaware corporation from engaging, under certain circumstances, in a business combination with an interested stockholder for a period of three years following the date the person became an interested stockholder unless:

• prior to the date of the transaction, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

• upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding, but not for determining the outstanding voting stock owned by the interested stockholder, (1) shares owned by persons who are directors and also officers, and (2) shares owned by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

• at or subsequent to the date of the transaction, the business combination is approved by the board of directors of the corporation and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock which is not owned by the interested stockholder.

117

Generally, a business combination includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. An interested stockholder is a person who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of a corporation’s outstanding voting stock. We expect the existence of this provision to have an anti-takeover effect with respect to transactions our board of directors does not approve in advance. We also anticipate that Section 203 may discourage business combinations or other attempts that might result in a premium over the market price for the shares of common stock held by our stockholders.

The provisions of Delaware law and our amended and restated certificate of incorporation and amended and restated bylaws could have the effect of discouraging others from attempting hostile takeovers and, as a consequence, may also inhibit temporary fluctuations in the market price of our common stock that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in our management. It is possible that these provisions could make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.

Our amended and restated certificate of incorporation requires, to the fullest extent permitted by law that derivative actions brought in our name, actions against our directors, officers and employees for breach of fiduciary duty and other similar actions may be brought only in the Court of Chancery in the State of Delaware. Although we believe this provision benefits us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors and officers.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Computershare Trust Company, N.A.

Listing

Our common stock is listed on the New York Stock Exchange under the symbol “HUBS.”

ITEM 13. Certain Relationships and Related Transactions, and Director Independence

In addition to the director and executive compensation arrangements discussed above in the sections of this Annual Report on Form 10-K captioned “Executive Compensation,” we have been a party to the following transactions since January 1, 2014, in which the amount involved exceeded or will exceed $120,000, and in which any director, executive officer or holder of more than 5% of any class of our voting stock, or any member of the immediate family of or entities affiliated with any of them, had or will have a material interest. We also describe below certain transactions and series of similar transactions since January 1, 2014 with our directors, executive officers, holders of more than 5% of any class of our voting securities, or any member of the immediate family of or any entities affiliated with any of the foregoing persons to which we are party.

We have adopted a written policy, which provides that our executive officers, directors, holders of more than 5% of any class of our voting securities, and any member of the immediate family of and any entity affiliated with any of the foregoing persons, are not permitted to enter into a related party transaction with us without the prior consent of our audit committee, or other disinterested members of our board of directors in the event that it is inappropriate for our audit committee to review such transaction due to a conflict of interest. Pursuant to such policy, any request for us to enter into a transaction with an executive officer, director, principal stockholder, or any of their immediate family members or affiliates, in which the amount involved exceeds $120,000 must first be presented to our audit committee for review, consideration and approval. In approving or rejecting any such proposal, our audit committee is to consider the relevant facts and circumstances available and deemed relevant to the audit committee, including, but not limited to, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the

118

same or similar circumstances and the extent of the related party’s interest in the transaction. All of the transactions described below were entered into prior to the adoption of this policy.

Limitation of Liability and Indemnification of Officers and Directors

Our amended and restated certificate of incorporation contains 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 breach of their duty of loyalty to our company or our stockholders;

• any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

• unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware General Corporation Law; or

• any transaction from which they derived an improper personal benefit.

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, we adopted amended and restated bylaws which 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 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 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, we have entered into indemnification agreements with each of our directors and executive officers that are broader than the specific indemnification provisions contained in the Delaware General Corporation Law. These indemnification agreements 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 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 included in our amended and restated certificate of incorporation, amended and restated bylaws and in indemnification agreements that we entered into or may in the future 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 harmed 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

119

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 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.

Other Transactions with Our Executive Officers and Directors and Affiliated Entities

We have granted stock options and RSUs to our executive officers and certain of our directors. See the section of this Annual Report on Form 10-K captioned “Executive Compensation—Outstanding Equity Awards at Fiscal Year-End” for a description of these stock options and RSUs.

Policies and Procedures for Related Party Transactions

The audit committee of our board of directors has 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. 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 provides that the audit committee shall review and approve or disapprove any related party transactions. We also adopted a formal policy governing the review and approval of related party transactions.

All of the transactions described above were entered into prior to the adoption of this policy. Accordingly, each was approved by disinterested members of our board of directors after making a determination that the transaction was executed on terms no less favorable than those that could have been obtained from an unrelated third party.

Commitments and Contingencies

8. Commitments and Contingencies

The Company leases its office facilities under non-cancelable operating leases that expire at various dates through November 2020. Rent expense for non-cancellable operating leases with free rental periods or scheduled rent increases is recognized on a straight-line basis over the terms of the leases. Improvement reimbursements from landlords of $3.3 million are being amortized on a straight-line basis into rent expense over the terms of the leases. The difference between required lease payments and rent expense has been recorded as deferred rent.

Rent expense was $4.9 million in 2014, $3.1 million in 2013, and $1.3 million in 2012. Deferred rent was $4.3 million as of December 31, 2014 and $2.5 million as of December 31, 2013.

In August 2011, the Company sublet a portion of its office space to an unrelated third party and entered into a sublease that expired in January 2014. Sublease income was $11 thousand in 2014, $135 thousand in 2013, and $130 thousand in 2012.

In October 2013, the Company extended a lease agreement for the purchase of equipment with a fair value of $299 thousand. The lease is payable in 36 monthly payments through September 2016. The total outstanding balance financed under capital leases was $178 thousand as of December 31, 2014, $299 thousand as of December 31, 2013. Amortization of assets recorded under capital leases is included in depreciation expense.

Future minimum payments under all operating and capital lease agreements as of December 31, 2014, are as follows:

On November 13, 2013, a putative class action complaint was filed in the Middlesex County Superior Court in the Commonwealth of Massachusetts, entitled Albert McCormack v. HubSpot, Inc. The complaint alleged that the Company maintained a policy of not paying overtime to its business development representatives for all hours worked in excess of 40 hours per week. The complaint sought unpaid wages, multiple damages, injunctive relief, attorneys’ fees and costs. The Company settled this matter for an immaterial amount and the complaint was dismissed on November 3, 2014.

In addition, from time to time the Company may become involved in legal proceedings or be subject to claims arising in the ordinary course of its business. Although the results of litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of these ordinary course matters will not have a material adverse effect on its business, operating results, financial condition or cash flows. Regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources and other factors.

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

3. Fair Value of Financial Instruments

The Company measures certain financial assets at fair value. Fair value is determined based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants, as determined by either the principal market or the most advantageous market. Inputs used in the valuation techniques to derive fair values are classified based on a three-level hierarchy, as follows:

• Level 1—Quoted prices in active markets for identical assets or liabilities.

• Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities.

• Level 3—Unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities.

The Company considers all highly liquid investments purchased with a remaining maturity of three months or less to be cash equivalents. The fair value of the Company’s investments in certain money market funds is their face value. Such instruments are classified as Level 1 and are included in cash and cash equivalents.

For certain other financial instruments, including accounts receivable, accounts payable and other current liabilities, the carrying amounts approximate their fair value due to the relatively short maturity of these balances.

The fair value of these financial assets was determined using the following inputs for the year end December 31, 2014. The Company did not have any cash equivalents at December 31, 2013.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Presentation —The consolidated financial statements have been prepared in U.S. dollars, in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. All intercompany transactions have been eliminated in consolidation.

Use of Estimates —The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Operating Segments —The Company operates as one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is regularly evaluated by the chief operating decision makers (“CODMs”), which are the Company’s chief executive officer and chief operating officer, in deciding how to allocate resources and assess performance. The Company’s CODMs evaluate the Company’s financial information and resources and assess the performance of these resources on a consolidated basis. Since the Company operates in one operating segment, all required financial segment information can be found in the consolidated financial statements.

Historical Loss Per Share —Basic net loss per share attributable to common stockholders is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period. 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, options to purchase common stock, common stock warrant, nonvested shares of restricted stock, RSUs and redeemable convertible preferred stock are considered to be common stock equivalents. The Company applied the two-class method to calculate its basic and diluted net loss per share of common stock, as its convertible preferred stock and common stock are participating securities. The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common stockholders. However, the two-class method does not impact the net loss per share of common stock as the Company was in a loss position for each of the periods presented and preferred stockholders do not participate in losses.

A reconciliation of the denominator used in the calculation of basic and diluted loss per share is as follows:

	Year Ended December 31,
	2014			2013			2012
	(in thousands, except per share amounts)
Numerator:
Net loss attributable to common stockholders	$	(48,560	)	$	(34,328	)	$	(18,859	)
Denominator:
Weighted-average common shares outstanding—basic		11,562			5,113			4,699
Dilutive effect of share equivalents resulting from stock options, RSUs, nonvested restricted stock, common stock warrant and redeemable convertible preferred shares (as converted)		—			—			—
Weighted-average common shares outstanding-diluted		11,562			5,113			4,699
Net loss per common share, basic and diluted	$	(4.20	)	$	(6.71	)	$	(4.01	)

For the years ended December 2014, 2013 and 2012, the Company incurred net losses and, therefore, the effect of the Company’s outstanding stock options, common stock warrant, redeemable convertible preferred stock, RSUs and nonvested shares of restricted stock was not included in the calculation of diluted loss per share as the effect would be anti-dilutive. The following table contains share totals with a potentially dilutive impact (in thousands):

	Year Ended December 31,
	2014		2013		2012
	(in thousands)
Options to purchase common shares		4,588		4,695		4,180
Common stock warrant		13		13		13
Common stock subject to repurchase		—		—		67
Convertible preferred shares (as converted)		—		19,530		19,530
RSUs		1,376		858		—

Cash and Cash Equivalents—The Company considers all highly liquid investments purchased with original maturity of three months or less to be cash equivalents. Cash and cash equivalents consist of cash held in bank deposit accounts and short-term, highly-liquid investments with remaining maturities of three months or less at the date of purchase, consisting of money-market funds.

Restricted Cash — The Company had restricted cash of $230 thousand at December 31, 2014 related to a leased facility. The Company had restricted cash of $1.9 million at December 31, 2013 which included $1.8 million for letters of credit for the Company’s leased facilities and $157 thousand in collateral for the Company’s corporate credit card borrowings. During the year ended December 31, 2014 the Company released from restrictions $1.7 million of cash, which includes the $157 thousand in collateral related to the Company’s corporate credit card borrowings and $1.5 million related to its leased facilities.

Accounts Receivable and Allowance for Doubtful Accounts —Accounts receivable are carried at the original invoiced amount less an allowance for doubtful accounts based on the probability of future collection. When management becomes aware of circumstances that may decrease the likelihood of collection, it records a specific allowance against amounts due, which reduces the receivable to the amount that management reasonably believes will be collected. For all other customers, management determines the adequacy of the allowance based on historical loss patterns, the number of days that billings are past due and an evaluation of the potential risk of loss associated with specific accounts. To date, losses resulting from uncollected receivables have not exceeded management’s expectations.

The following is a rollforward of the Company’s allowance for doubtful accounts (in thousands):

	Balance Beginning of Period		Charged to Costs or Expenses		Deductions (1)			Balance at End of Period
Allowance for doubtful accounts
Year ended December 31, 2014	$	175	$	632	$	(589	)	$	218
Year ended December 31, 2013	$	122	$	523	$	(470	)	$	175
Year ended December 31, 2012	$	61	$	384	$	(323	)	$	122

(1) Deductions include actual accounts written-off, net of recoveries.

Property and Equipment —Property and equipment are stated at cost and depreciated using the straight-line method over the estimated useful lives of the related assets. Expenditures for maintenance and repairs are charged to expense as incurred, whereas major betterments are capitalized as additions to leasehold improvements. Depreciation is recorded over the following estimated useful lives:

	Estimated Useful Life
Computer equipment and purchased software	3 years
Office equipment	5 years
Furniture and fixtures	5 years
Leasehold improvements	Lesser of lease term or useful life

Impairment of Long-Lived Assets —Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable or that the useful lives of those assets are no longer appropriate. Management considers the following potential indicators of impairment of its long-lived assets (asset group): a substantial decrease in the Company’s stock price, a significant adverse change in the extent or manner in which a long-lived asset (asset group) is being used, a significant adverse change in legal factors or in the business climate that could affect the value of the long-lived asset (asset group), an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a long-lived asset (asset group), and a current expectation that, more likely than not, a long lived asset (asset group) will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. When such events occur, the Company compares the carrying amounts of the assets to their undiscounted expected future cash flows. If this comparison indicates that there may be an impairment, the amount of the impairment is calculated as the difference between the carrying value and fair value. For the years presented, the Company did not recognize an impairment charge.

Goodwill —Goodwill represents the excess of cost over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. The Company has no other intangible assets with indefinite useful lives. Goodwill is not subject to amortization, but is monitored annually for impairment or more frequently if there are indicators of impairment. Management considers the following potential indicators of impairment: significant underperformance relative to historical or projected future operating results, significant changes in the Company’s use of acquired assets or the strategy of the Company’s overall business, significant negative industry or economic trends and a significant decline in the Company’s stock price for a sustained period. The Company performs its annual impairment test on November 30. Currently, the Company’s goodwill is evaluated at the entity level as it is determined there is only one reporting unit. The Company performs a two step impairment test. In the first step, the fair value of each reporting unit is compared to its carrying amount. If the fair value exceeds the carrying value of the net assets assigned, goodwill is not considered impaired and the second step is not required. If the carrying value exceeds the fair value, then the second step of the impairment test is performed in order to determine the implied fair value of the reporting unit’s goodwill. If the carrying value of the goodwill exceeds the fair value, then an impairment charge is recorded. On November 30, 2014, the estimated fair value of the Company’s single reporting unit exceeded its carrying amount. Because the fair value of the Company’s single reporting unit was in excess of its carrying value and there were no indicators that the Company’s goodwill had become impaired since that date, there was no impairment as of November 30, 2014 through December 31, 2014.

For the years ended December 31, 2014, 2013 and 2012, the Company did not recognize an impairment charge.

Advertising Expense —The Company expenses advertising as incurred, which is included in sales and marketing expense in the accompanying consolidated statements of operations. The Company incurred $3.3 million of advertising expense in 2014, $3.5 million in 2013, and $3.0 million in 2012.

Revenue Recognition —The Company primarily generates revenue from multi-element arrangements, which typically include subscriptions to its online software solution and professional services which includes on-boarding and training services. The Company’s customers do not have the right to take possession of the online software solution. The Company recognizes revenue when all of the following have occurred:

• persuasive evidence of an arrangement with the customer exists;

• service has been or is being provided;

• the fees are fixed or determinable; and

• collectability of the fees is reasonably assured.

The Company’s arrangements do not contain general rights of return.

In order to treat elements in a multiple-element arrangement as separate units of accounting, the delivered elements must have standalone value and delivery of the undelivered element is probable and within control of the Company.

The Company has determined that subscriptions for its online software solution have standalone value because, once a customer launches its initial site, the online software solution is fully functional and does not require any additional development, modification, or customization.

Professional services consists primarily of on-boarding and web-based and in-person training, are not required to use the online software solution, and are determined to have stand-alone value from the related subscription services because they are sold separately by the Company and third parties.

When multiple element arrangements are separated into different units of accounting, the arrangement consideration is allocated to the identified separate units based on a relative selling price hierarchy. The estimated fair value of each element is determined based upon the following hierarchy: (1) vendor specific objective evidence (“VSOE”) of fair value, (2) third party evidence of selling price (“TPE”), or (3) the Company’s best estimate of selling price (“BESP”). The Company is not able to establish VSOE of fair value for undelivered elements, which in most instances is subscription and training and professional services, based on its pricing practices, and there is not a reliable measure of TPE of selling price. As such, arrangement consideration is allocated amongst multiple deliverable arrangements using BESP. The Company establishes BESP for each deliverable primarily considering the median of actual sales prices of each type of subscription and other professional services sold. The Company considers each type of subscription and service as well as pricing and geographic information when establishing BESP. Arrangement consideration is allocated such that the revenue recognized does not exceed the fee subject to refund.

Revenue from subscriptions is recognized ratably over the subscription period beginning on the date the Company’s subscription is made available to customers. Substantially all subscription contracts are one year or less. The Company recognizes revenue from on-boarding and training services as the services are provided.

The Company pays its marketing agency partners a commission of the subscription sales price for sales to customers. The classification of the commission paid on the Company’s consolidated statements of operations depends on who is purchasing its subscription. In instances where the customer is purchasing the subscription, the Company is the primary obligor and records the commission paid to the agency partner as sales and marketing expense. When the agency partner purchases the subscription directly from the Company, the Company nets the consideration paid to the partner against the associated revenue it recognizes, as in these instances the Company’s customer is the partner and the Company’s remaining obligations are to the partner. The Company does not believe that it receives a tangible benefit from the payment back to the partner.

Sales taxes collected from customers and remitted to government authorities are excluded from revenue.

Amounts that have been invoiced are recorded in accounts receivable and deferred revenue or revenue, depending on whether the revenue recognition criteria have been met. Deferred revenue represents amounts billed for which revenue has not yet been recognized. Deferred revenue that will be recognized during the succeeding 12-month period is recorded as current deferred revenue and the remaining portion is recorded as long-term deferred revenue.

Concentrations of Credit Risk and Significant Customers —Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, restricted cash and accounts receivable.

A significant portion of the Company’s cash is held at one financial institution that management believes to be of high credit quality. Although the Company deposits it cash with multiple financial institutions, its deposits exceed federally insured limits.

The Company has no significant off-balance sheet risk such as foreign exchange contracts, option contracts, or other hedging arrangements.

The Company generally does not require collateral from its customers and generally requires payment 30 days from the invoice date. The Company maintains an allowance for doubtful accounts based on its assessment of the collectability of accounts receivable. Credit risk arising from accounts receivable is mitigated as a result of transacting with a large number of geographically dispersed customers spread across various industries.

At December 31, 2014 and 2013 there were no customers that represented more than 10% of the net accounts receivable balance. There were no customers that individually exceeded 10% of the Company’s revenue in any of the periods presented.

Foreign Currency —The functional currency of the Company’s foreign subsidiaries is the local currency. Assets and liabilities denominated in a foreign currency are translated into U.S. dollars at the exchange rates in effect at the balance sheet dates; with the resulting translation adjustments directly recorded to a separate component of accumulated other comprehensive income (loss). Income and expense accounts are translated at the weighted-average exchange rates during the period. Equity transactions are translated at historical exchange rates. Foreign currency transaction gains and losses are recorded in other income (expense).

Research and Development —Research and development expenses include payroll, employee benefits and other expenses associated with product development.

Capitalized Software Development Costs —Certain payroll and stock compensation costs incurred to develop functionality for the Company’s software platform, as well as certain upgrades and enhancements that are expected to result in increased functionality are capitalized. The costs incurred in the preliminary stages of development are expensed as incurred. Once an application has reached the development stage, certain internal costs are capitalized until the software is substantially complete and ready for its intended use. Capitalized software development costs are amortized on a straight-line basis over their estimated useful life of two years. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets.

Capitalized software development costs consisted of the following:

	December 31,
	2014			2013
	(in thousands)
Gross capitalized software development costs	$	14,219		$	9,351
Accumulated amortization		(9,786	)		(5,872	)
Capitalized software development costs, net	$	4,433		$	3,479

The Company capitalized software development costs of $4.9 million in 2014, $3.7 million in 2013, and $2.4 million in 2012. Stock-based compensation costs included in capitalized software were $235 thousand in 2014, $273 thousand in 2013, and $100 thousand in 2012.

Amortization of capitalized software development costs was $3.9 million in 2014, $2.6 million in 2013, and $1.5 million in 2012. Amortization expense is included in cost of revenue in the consolidated statements of operations.

Income Taxes —Deferred tax assets and liabilities are recognized for the differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities using tax rates expected to be in effect in the years in which the differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will not be realized.

The Company provides reserves for potential payments of tax to various tax authorities related to uncertain tax positions based on a determination of whether and how much of a tax benefit taken by the Company in its tax filings or positions is more likely than not to be realized following resolution of any potential contingencies present related to the tax benefit. Potential interest and penalties associated with such uncertain tax positions are recorded as a component of income tax expense.

Stock-Based Compensation —The Company accounts for all stock options and awards granted to employees and nonemployees using a fair value method. Stock-based compensation is recognized as an expense and is measured at the fair value of the award. The measurement date for employee awards is generally the date of the grant. The measurement date for nonemployee awards is generally the date the options vest. Stock-based compensation costs are recognized as expense over the requisite service period, which is generally the vesting period for awards, on a straight-line basis for awards with only a service condition, and using the graded-method for awards with both a performance and service that were granted prior to our IPO, and on a straight-line basis for the awards that were granted following our IPO.

Recent Accounting Pronouncements—In May 2014, the Financial Accounting Standards Board issued updated guidance and disclosure requirements for recognizing revenue. The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance will be effective for the Company on January 1, 2017 and may be applied retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is evaluating the potential impact of adopting this new accounting guidance.

In June 2014, the Financial Accounting Standards Board issued a standards update on accounting for share-based payments when the terms of the award provide that a performance target could be achieved after a requisite service period. The standard is effective beginning January 1, 2016, with early adoption permitted. We do not expect it to have a material impact on our consolidated financial position, results of operations or cash flows.

In 2014, the Company had a current state and foreign income tax expense of $(20) thousand and $(12) thousand, respectively, and a deferred foreign income tax benefit of $124 thousand, in 2014.

Deferred Tax Assets and Liabilities—Deferred income taxes reflect the net 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 were as follows:

	Year Ended December 31,
	2014			2013			2012
	(in thousands)
Deferred tax assets:
Net operating loss carryforwards	$	46,615		$	35,077		$	23,810

Valuation allowance		(55,221	)		(38,383	)		(26,016	)
Net deferred tax assets	$	124		$	—		$	—

The Company reviews all available evidence to evaluate its recovery of deferred tax assets, including its recent history of accumulated losses in all tax jurisdictions over the most recent three years as well as its ability to generate income in future periods. The Company has provided a valuation allowance against its U.S. net deferred tax assets as it is more likely than not that these assets will not be realized given the nature of the assets and the likelihood of future utilization.

The valuation allowance increased by $16.8 million in 2014, $12.4 million in 2013, and $7.0 million in 2012 due to the increase in the deferred tax assets by approximately the same amounts (primarily due to the increase in the net operating loss carryforwards).

U.S. income taxes on the undistributed earnings of the Company’s two non-U.S. subsidiaries have not been provided for as the Company currently plans to indefinitely reinvest these amounts and has the ability to do so. Cumulative undistributed foreign earnings were not material at December 31, 2014 and December 31, 2013. The Company does not believe it is practicable to estimate with reasonable accuracy the hypothetical amount of the unrecognized deferred tax liability on undistributed foreign earnings given the many factors and assumptions required to estimate the taxable amount after reduction for available foreign tax credits.

The Company had federal and state net operating loss carryforwards of $124.3 million and $79.7 million, respectively at December 31, 2014, which expire at various dates through 2034. The Company has generated net operating loss carryforwards from stock compensation deductions and the amount of federal and state excess tax benefits totaling $1.5 million will be credited to additional paid-in capital when realized.

The Company had federal research and development credit carryforwards of $2.7 million at December 31, 2014 that expire at various dates through 2034. The Company also has state research and investment credit carryforwards of $1.7 million and $320 thousand, respectively that expire at various dates through 2034.

On December 19, 2014 the Tax Increase Prevention Act was signed into law. The Act contains provisions that extended the federal research credit through the end of 2014. The federal research credit provisions had previously expired at the end of 2013. A benefit of $839 thousand for 2014 federal research credit is reflected in the financial statements.

Uncertain Tax Positions—The Company accounts for uncertainty in income taxes using a two-step process. The Company first determines whether it is more likely than not that a tax position will be sustained upon examination by the tax authority, including resolutions of any related appeals or litigation processes, based on technical merit. If a tax position meets the more-likely-than-not recognition threshold it is then measured to determine the amount of benefit to recognize in the financial statements. The tax position is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement.

The following summarizes activity related to unrecognized tax benefits:

	Year Ended December 31,
	2014		2013		2012
	(in thousands)
Unrecognized benefit—beginning of the year	$	1,030	$	667	$	552
Gross increases—current period positions		683		363		115
Unrecognized benefit—end of period	$	1,713	$	1,030	$	667

All of the unrecognized tax benefits decrease deferred tax assets with a corresponding decrease to the valuation allowance. None of the unrecognized tax benefits would affect the Company’s effective tax rate if recognized in the future.

The Company has elected to recognize interest and penalties related to uncertain tax positions as a component of income tax expense. No interest or penalties have been recorded through December 31, 2014.

The Company does not expect any significant change in its unrecognized tax benefits within the next 12 months.

The Company files tax returns in the United States, Ireland, Australia, and various state jurisdictions. All of the Company’s tax years remain open to examination by major taxing jurisdictions to which the Company is subject, as carryforward attributes generated in past years may still be adjusted upon examination by the Internal Revenue Service or state and foreign tax authorities if they have or will be used in future periods. The Company is routinely examined by various taxing authorities. The Company does not expect that the results of ongoing examinations will have a material effect on its financial condition or results of operations.

Reverse Stock Split

10. Reverse Stock Split

On September 25, 2014, the Company’s Board of Directors and stockholders approved a 1-for-3 reverse stock split of the Company’s common stock. The reverse stock split became effective on September 25, 2014. Upon the effectiveness of the reverse stock split, (i) every three shares of outstanding common stock was combined into one share of common stock, (ii) the number of shares of common stock into which each outstanding warrant or option to purchase common stock is exercisable was proportionally decreased, (iii) the exercise price of each outstanding warrant or option to purchase common stock was proportionately increased, and (iv) the conversion ratio for each share of preferred stock outstanding was proportionately reduced. Unless otherwise indicated, all of the share numbers, share prices and exercise prices in these consolidated financial statements have been adjusted, on a retroactive basis, to reflect this 1-for-3 reverse stock split.

Equipment Line—In June 2010, the Company executed a loan and security agreement (the “Loan Agreement”) establishing a $500,000 equipment line of credit (the “Equipment Line”) with a bank for eligible equipment purchases through June 28, 2011. Borrowings under the Line were due in 24 equal monthly payments of principal, plus accrued interest, at an annual rate of 3.25% beginning July 1, 2011 through June 1, 2013. Borrowings were collateralized by the equipment, software and other property financed by the Loan Agreement. The Company was required to maintain certain non-financial covenants. The Equipment Line expired on June 1, 2013 and was not renewed.

Growth Capital and Revolving Line—In April 2012, the Company amended and restated the Loan Agreement. The Company could borrow up to $5.0 million on a growth capital line of credit (“Growth Capital Line”) through April 2013, at the bank’s prime rate plus one percent. The Growth Capital Line was repayable beginning May 2013 in monthly installments of principal and interest through October 2015. The Company could borrow up to $5.0 million on a revolving line of credit (“Revolving Line”) at the bank’s prime rate, which was payable in full in October 2013. Both lines were established to provide financing for general corporate purposes. The Company was required to maintain a minimum cash account balance of $1.0 million and all of the Company’s assets, excluding intellectual property, was pledged as collateral.

As part of the amended and restated Loan Agreement, the Company issued the bank a fully exercisable warrant to purchase 13,158 shares of common stock at an exercise price of $5.70 per share with an expiration date of April 2022. The fair value of the warrant of $50 thousand was recorded as interest expense in 2012 as it was issued fully vested. The fair value of the warrant was estimated on the date of the grant using the Black-Scholes option-pricing model with the following assumptions:

Risk-free interest rate	2.25	%
Expected term (in years)	10
Volatility	55	%
Expected dividends	—	%

In May 2013, the Company executed the first amendment to the amended and restated Loan Agreement. The Growth Capital Line was extended through May 2014 and was repayable beginning June 2014 in monthly installments of principal and interest through November 2016. The Revolving Line was extended through May 2014.

In September 2013, the Company executed the second amendment to the amended and restated Loan Agreement, increasing the Revolving Line to $20.0 million and extending the maturity date to December 31, 2014. A 0.25% annual unused facility fee is applicable to the Revolving Line.

In March 2014, the Company executed the third amendment to the amended and restated Loan Agreement. The Growth Capital Line was extended with borrowings available through December 2014 and repayable over 30 months through June 2017. Additionally, the Revolving Line was increased to $30.0 million and is payable in full in March 2016.

In September 2014, the Company amended its Loan Agreement to combine its $5.0 million Growth Capital Line and $30.0 million Revolving Line into a single $35.0 million Revolving Line. The interest rate on the new Revolving Line is the bank’s prime rate plus 0.5% and is due in full in March 2016. During 2014 the Company drew down $18 million under the Revolving line. In October 2014, in connection with the Company’s IPO, the Company paid off the $18.0 million outstanding balance under the Revolving Line and there is no outstanding balance under the Revolving Line at December 31, 2014.

Equity Incentive Plan—The Company’s 2007 Equity Incentive Plan (the “2007 Plan”) was terminated in connection with the IPO, and accordingly, no shares are available for issuance under the 2007 Plan. The 2007 Plan will continue to govern outstanding awards granted thereunder, The 2007 Plan provided for the grant of qualified incentive stock options and nonqualified stock options or other awards such as RSUs to the Company’s employees, officers, directors and outside consultants. As of December 31, 2014, 4.4 million options to purchase common stock and 1.3 million RSUs remained outstanding under the 2007 Plan.

On September 25, 2014, the Company’s board of directors adopted and the Company’s stockholders approved the 2014 Stock Option and Incentive Plan (the “2014 Plan”). The 2014 Plan became effective upon the closing of the Company’s IPO. The Company initially reserved 1,973,551 shares of its common stock, or the Initial Limit, for the issuance of awards under the 2014 Plan. The 2014 Plan provides that the number of shares reserved and available for issuance under the plan automatically increases each January 1, beginning on January 1, 2015, by 5% of the outstanding number of shares of the Company’s common stock on the immediately preceding December 31 or such lesser number of shares as determined by the compensation committee. This number is subject to adjustment in the event of a stock split, stock dividend or other change in the Company’s capitalization. As of December 31, 2014, 140 thousand options to purchase common stock and 35 thousand RSUs remained outstanding under the 2014 Plan.

Equity Compensation Expense—The Company’s equity compensation expense is comprised of awards of options to purchase common stock, restricted stock awards (RSAs) and RSUs.

The following two tables show stock compensation expense by award type and where the stock compensation expense is recorded in the Company’s consolidated statements of operations (in thousands):

Excluded from stock-based compensation expense is $235 thousand of capitalized software development costs in 2014, $273 thousand in 2013, and $100 thousand in 2012.

Stock Options—The fair value of employee options is estimated on the date of each grant using the Black-Scholes option-pricing model with the following assumptions:

	Year Ended December 31,
	2014	2013	2012
Risk-free interest rate	1.79% - 2.67%	0.82% - 1.86%	0.56% - 1.23%
Expected term (in years)	5.0 - 6.5	4.6 - 6.5	3.5 - 6.5
Volatility	44.8% - 50.9%	46.8% - 54.7%	48% - 51%
Expected dividends	—	—	—

The weighted-average grant-date fair value of options granted was $9.72 per share in 2014, $6.84 per share in 2013, and $3.09 per share in 2012.

The interest rate was based on the U.S. Treasury bond rate at the date of grant with a maturity approximately equal to the expected term. The expected term of options granted to employees was calculated using the simplified method, which represents the average of the contractual term of the option and the weighted-average vesting period of the option. The expected term of options granted to nonemployees is equal to the remaining contractual term as of the measurement date. Expected volatility for the Company’s common stock was based on an average of the historical volatility of a peer group of similar public companies. The assumed dividend yield is based upon the Company’s expectation of not paying dividends in the foreseeable future. The estimation of share-based awards that will ultimately vest requires judgment, and to the extent actual results differ from the Company’s estimates, such amounts will be recorded as an adjustment in the period estimates are revised.

Prior to the Company’s IPO, the fair value of the common stock was determined by the Board of Directors at each award grant date based upon a variety of factors, including the results obtained from independent third-party valuations, the Company’s financial position and historical financial performance, the status of technological developments within the Company’s products, the composition and ability of the engineering and management team, an evaluation of benchmark of the Company’s competition, the climate in the marketplace, the illiquid nature of the common stock, arm’s-length sales of the Company’s capital stock (including redeemable convertible preferred stock), the effect of the rights and preferences of the preferred stockholders and the prospects of a liquidity event, among others. After the Company’s IPO, the fair value of the Company’s common stock is the closing price of the stock on the date of grant.

The stock option activity for the year ended December 31, 2014 is as follows:

	Options (in thousands)			Weighted- Average Exercise Price		Weighted- Average Remaining Life (in years)		Aggregate Intrinsic Value (in thousands)
Outstanding—December 31, 2013		4,695		$	6.66		8.0	$	37,651
Granted		1,067			19.39
Exercised		(850	)		4.46
Forfeited/expired		(324	)		12.10
Outstanding—December 31, 2014		4,588			9.64		7.6	$	110,396
Options vested or expected to vest—December 31, 2014		4,296		$	9.14		7.5	$	105,418
Options exercisable—December 31, 2014		2,438		$	5.90		6.8	$	67,557

Total unrecognized compensation cost related to the nonvested options granted under the 2007 Plan and the 2014 Plan was $10.4 million at December 31, 2014. That cost is expected to be recognized over a weighted-average period of 2.8 years as of December 31, 2014.

Common Stock Warrant—In 2012, in conjunction with the revolving and term loan agreement (see Note 6), the Company issued a warrant to purchase 13 thousand shares of common stock at an exercise price of $5.70 per share with an expiration date of April 2022. The warrant is exercisable and outstanding at December 31, 2013 and December 31, 2014.

Restricted Stock Awards—In June 2011, in connection with the Performable acquisition, the Company issued 220 thousand shares of restricted common stock to former Performable employees. These shares were subject to repurchase agreements and if the holder ceased to have a business relationship with the Company, the Company could repurchase any unvested shares of common stock held by these individuals at prices that ranged from $0.00143 to $0.855 per share. These shares were issued for no consideration and therefore the fair value of these shares of $1.2 million was recorded as compensation expense over the vesting period. As of December 31, 2013 the Company’s right to repurchase the RSAs had fully lapsed.

During 2012, the Company reclassified $2 thousand into stockholder’s deficit representing the amounts no longer subject to repurchase for 90 thousand shares that vested during the year. During 2013, the Company reclassified $2 thousand into stockholder’s deficit representing the amounts no longer subject to repurchase for 67 thousand shares that vested during the year.

The activity for the RSAs for the year ended December 31, 2013, is as follows:

	Restricted Shares (in thousands)			Weighted- Average Grant-Date Fair Value
Outstanding—January 1, 2013		67		$	5.70
Lapse in Company buyback right		(67	)	$	5.70
Outstanding—December 31, 2013		—

Restricted Stock Units—RSUs vest upon achievement of a service condition and a performance condition. As soon as practicable following each vesting date, the Company will issue to the holder of the RSUs the number of shares of common stock equal to the aggregate number of RSUs that have vested. Notwithstanding the foregoing, the Company may, in its sole discretion, in lieu of issuing shares of common stock to the holder of the RSUs, pay the holder an amount in cash equal to the fair market value of such shares of common stock. The service condition is a time-based condition met over a period of four years, with 25% met after one year, and then in equal monthly installments over the succeeding three years. The performance condition is met upon a sale event or six months following the Company’s IPO, which was not considered probable as of December 31, 2013 and therefore no stock-based compensation expense was recorded in the consolidated financial statements as of that date. Upon completion of the Company’s IPO the Company began recording stock-based compensation expense based on the grant-date fair value of the RSUs using the accelerated attribution method for RSUs granted prior to its IPO and using the straight-line method for RSUs granted following its IPO, net of estimated forfeitures. The stock compensation expense associated with RSUs where the service condition had been met prior to the IPO was also recognized on the date of the IPO, using the accelerated attribution method. The total stock-based compensation expense expected to be recorded over the remaining life of outstanding RSUs is approximately $10.5 million at December 31, 2014. That cost is expected to be recognized over a weighted-average period of 3.3 years as of December 31, 2014. As of December 31, 2014 there are 905 thousand RSUs expected to vest with an aggregate intrinsic value of $30.4 million.

The following table summarizes the activity related to RSUs for the year ended December 31, 2014:

	RSUs Outstanding
	Shares (in thousands)			Weighted-Average Grant Date Fair Value Per Share
Unvested and outstanding at December 31, 2013		858		$	13.29

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2014

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation — The consolidated financial statements have been prepared in U.S. dollars, in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. All intercompany transactions have been eliminated in consolidation.

Use of Estimates

Use of Estimates — The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Operating Segments

Operating Segments — The Company operates as one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is regularly evaluated by the chief operating decision makers (“CODMs”), which are the Company’s chief executive officer and chief operating officer, in deciding how to allocate resources and assess performance. The Company’s CODMs evaluate the Company’s financial information and resources and assess the performance of these resources on a consolidated basis. Since the Company operates in one operating segment, all required financial segment information can be found in the consolidated financial statements.

Historical Loss Per Share

Historical Loss Per Share — Basic net loss per share attributable to common stockholders is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period. 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, options to purchase common stock, common stock warrant, nonvested shares of restricted stock, RSUs and redeemable convertible preferred stock are considered to be common stock equivalents. The Company applied the two-class method to calculate its basic and diluted net loss per share of common stock, as its convertible preferred stock and common stock are participating securities. The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common stockholders. However, the two-class method does not impact the net loss per share of common stock as the Company was in a loss position for each of the periods presented and preferred stockholders do not participate in losses.

A reconciliation of the denominator used in the calculation of basic and diluted loss per share is as follows:

	Year Ended December 31,
	2014			2013			2012
	(in thousands, except per share amounts)
Numerator:
Net loss attributable to common stockholders	$	(48,560	)	$	(34,328	)	$	(18,859	)
Denominator:
Weighted-average common shares outstanding—basic		11,562			5,113			4,699
Dilutive effect of share equivalents resulting from stock options, RSUs, nonvested restricted stock, common stock warrant and redeemable convertible preferred shares (as converted)		—			—			—
Weighted-average common shares outstanding-diluted		11,562			5,113			4,699
Net loss per common share, basic and diluted	$	(4.20	)	$	(6.71	)	$	(4.01	)

For the years ended December 2014, 2013 and 2012, the Company incurred net losses and, therefore, the effect of the Company’s outstanding stock options, common stock warrant, redeemable convertible preferred stock, RSUs and nonvested shares of restricted stock was not included in the calculation of diluted loss per share as the effect would be anti-dilutive. The following table contains share totals with a potentially dilutive impact (in thousands):

	Year Ended December 31,
	2014		2013		2012
	(in thousands)
Options to purchase common shares		4,588		4,695		4,180
Common stock warrant		13		13		13
Common stock subject to repurchase		—		—		67
Convertible preferred shares (as converted)		—		19,530		19,530
RSUs		1,376		858		—

Cash and Cash Equivalents

Cash and Cash Equivalents—The Company considers all highly liquid investments purchased with original maturity of three months or less to be cash equivalents. Cash and cash equivalents consist of cash held in bank deposit accounts and short-term, highly-liquid investments with remaining maturities of three months or less at the date of purchase, consisting of money-market funds.

Restricted Cash

Restricted Cash — The Company had restricted cash of $230 thousand at December 31, 2014 related to a leased facility. The Company had restricted cash of $1.9 million at December 31, 2013 which included $1.8 million for letters of credit for the Company’s leased facilities and $157 thousand in collateral for the Company’s corporate credit card borrowings. During the year ended December 31, 2014 the Company released from restrictions $1.7 million of cash, which includes the $157 thousand in collateral related to the Company’s corporate credit card borrowings and $1.5 million related to its leased facilities.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts Receivable and Allowance for Doubtful Accounts —Accounts receivable are carried at the original invoiced amount less an allowance for doubtful accounts based on the probability of future collection. When management becomes aware of circumstances that may decrease the likelihood of collection, it records a specific allowance against amounts due, which reduces the receivable to the amount that management reasonably believes will be collected. For all other customers, management determines the adequacy of the allowance based on historical loss patterns, the number of days that billings are past due and an evaluation of the potential risk of loss associated with specific accounts. To date, losses resulting from uncollected receivables have not exceeded management’s expectations.

The following is a rollforward of the Company’s allowance for doubtful accounts (in thousands):

	Balance Beginning of Period		Charged to Costs or Expenses		Deductions (1)			Balance at End of Period
Allowance for doubtful accounts
Year ended December 31, 2014	$	175	$	632	$	(589	)	$	218
Year ended December 31, 2013	$	122	$	523	$	(470	)	$	175
Year ended December 31, 2012	$	61	$	384	$	(323	)	$	122

(1) Deductions include actual accounts written-off, net of recoveries.

Property and Equipment

Property and Equipment — Property and equipment are stated at cost and depreciated using the straight-line method over the estimated useful lives of the related assets. Expenditures for maintenance and repairs are charged to expense as incurred, whereas major betterments are capitalized as additions to leasehold improvements. Depreciation is recorded over the following estimated useful lives:

	Estimated Useful Life
Computer equipment and purchased software	3 years
Office equipment	5 years
Furniture and fixtures	5 years
Leasehold improvements	Lesser of lease term or useful life

Impairment of Long-Lived Assets

Impairment of Long-Lived Assets — Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable or that the useful lives of those assets are no longer appropriate. Management considers the following potential indicators of impairment of its long-lived assets (asset group): a substantial decrease in the Company’s stock price, a significant adverse change in the extent or manner in which a long-lived asset (asset group) is being used, a significant adverse change in legal factors or in the business climate that could affect the value of the long-lived asset (asset group), an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a long-lived asset (asset group), and a current expectation that, more likely than not, a long lived asset (asset group) will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. When such events occur, the Company compares the carrying amounts of the assets to their undiscounted expected future cash flows. If this comparison indicates that there may be an impairment, the amount of the impairment is calculated as the difference between the carrying value and fair value. For the years presented, the Company did not recognize an impairment charge.

Goodwill

Goodwill — Goodwill represents the excess of cost over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. The Company has no other intangible assets with indefinite useful lives. Goodwill is not subject to amortization, but is monitored annually for impairment or more frequently if there are indicators of impairment. Management considers the following potential indicators of impairment: significant underperformance relative to historical or projected future operating results, significant changes in the Company’s use of acquired assets or the strategy of the Company’s overall business, significant negative industry or economic trends and a significant decline in the Company’s stock price for a sustained period. The Company performs its annual impairment test on November 30. Currently, the Company’s goodwill is evaluated at the entity level as it is determined there is only one reporting unit. The Company performs a two step impairment test. In the first step, the fair value of each reporting unit is compared to its carrying amount. If the fair value exceeds the carrying value of the net assets assigned, goodwill is not considered impaired and the second step is not required. If the carrying value exceeds the fair value, then the second step of the impairment test is performed in order to determine the implied fair value of the reporting unit’s goodwill. If the carrying value of the goodwill exceeds the fair value, then an impairment charge is recorded. On November 30, 2014, the estimated fair value of the Company’s single reporting unit exceeded its carrying amount. Because the fair value of the Company’s single reporting unit was in excess of its carrying value and there were no indicators that the Company’s goodwill had become impaired since that date, there was no impairment as of November 30, 2014 through December 31, 2014.

For the years ended December 31, 2014, 2013 and 2012, the Company did not recognize an impairment charge.

Advertising Expense

Advertising Expense — The Company expenses advertising as incurred, which is included in sales and marketing expense in the accompanying consolidated statements of operations. The Company incurred $3.3 million of advertising expense in 2014, $3.5 million in 2013, and $3.0 million in 2012.

Revenue Recognition

Revenue Recognition —The Company primarily generates revenue from multi-element arrangements, which typically include subscriptions to its online software solution and professional services which includes on-boarding and training services. The Company’s customers do not have the right to take possession of the online software solution. The Company recognizes revenue when all of the following have occurred:

• persuasive evidence of an arrangement with the customer exists;

• service has been or is being provided;

• the fees are fixed or determinable; and

• collectability of the fees is reasonably assured.

The Company’s arrangements do not contain general rights of return.

In order to treat elements in a multiple-element arrangement as separate units of accounting, the delivered elements must have standalone value and delivery of the undelivered element is probable and within control of the Company.

The Company has determined that subscriptions for its online software solution have standalone value because, once a customer launches its initial site, the online software solution is fully functional and does not require any additional development, modification, or customization.

Professional services consists primarily of on-boarding and web-based and in-person training, are not required to use the online software solution, and are determined to have stand-alone value from the related subscription services because they are sold separately by the Company and third parties.

When multiple element arrangements are separated into different units of accounting, the arrangement consideration is allocated to the identified separate units based on a relative selling price hierarchy. The estimated fair value of each element is determined based upon the following hierarchy: (1) vendor specific objective evidence (“VSOE”) of fair value, (2) third party evidence of selling price (“TPE”), or (3) the Company’s best estimate of selling price (“BESP”). The Company is not able to establish VSOE of fair value for undelivered elements, which in most instances is subscription and training and professional services, based on its pricing practices, and there is not a reliable measure of TPE of selling price. As such, arrangement consideration is allocated amongst multiple deliverable arrangements using BESP. The Company establishes BESP for each deliverable primarily considering the median of actual sales prices of each type of subscription and other professional services sold. The Company considers each type of subscription and service as well as pricing and geographic information when establishing BESP. Arrangement consideration is allocated such that the revenue recognized does not exceed the fee subject to refund.

Revenue from subscriptions is recognized ratably over the subscription period beginning on the date the Company’s subscription is made available to customers. Substantially all subscription contracts are one year or less. The Company recognizes revenue from on-boarding and training services as the services are provided.

The Company pays its marketing agency partners a commission of the subscription sales price for sales to customers. The classification of the commission paid on the Company’s consolidated statements of operations depends on who is purchasing its subscription. In instances where the customer is purchasing the subscription, the Company is the primary obligor and records the commission paid to the agency partner as sales and marketing expense. When the agency partner purchases the subscription directly from the Company, the Company nets the consideration paid to the partner against the associated revenue it recognizes, as in these instances the Company’s customer is the partner and the Company’s remaining obligations are to the partner. The Company does not believe that it receives a tangible benefit from the payment back to the partner.

Sales taxes collected from customers and remitted to government authorities are excluded from revenue.

Amounts that have been invoiced are recorded in accounts receivable and deferred revenue or revenue, depending on whether the revenue recognition criteria have been met. Deferred revenue represents amounts billed for which revenue has not yet been recognized. Deferred revenue that will be recognized during the succeeding 12-month period is recorded as current deferred revenue and the remaining portion is recorded as long-term deferred revenue.

Concentrations of Credit Risk and Significant Customers

Concentrations of Credit Risk and Significant Customers —Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, restricted cash and accounts receivable.

A significant portion of the Company’s cash is held at one financial institution that management believes to be of high credit quality. Although the Company deposits it cash with multiple financial institutions, its deposits exceed federally insured limits.

The Company has no significant off-balance sheet risk such as foreign exchange contracts, option contracts, or other hedging arrangements.

The Company generally does not require collateral from its customers and generally requires payment 30 days from the invoice date. The Company maintains an allowance for doubtful accounts based on its assessment of the collectability of accounts receivable. Credit risk arising from accounts receivable is mitigated as a result of transacting with a large number of geographically dispersed customers spread across various industries.

At December 31, 2014 and 2013 there were no customers that represented more than 10% of the net accounts receivable balance. There were no customers that individually exceeded 10% of the Company’s revenue in any of the periods presented.

Foreign Currency

Foreign Currency — The functional currency of the Company’s foreign subsidiaries is the local currency. Assets and liabilities denominated in a foreign currency are translated into U.S. dollars at the exchange rates in effect at the balance sheet dates; with the resulting translation adjustments directly recorded to a separate component of accumulated other comprehensive income (loss). Income and expense accounts are translated at the weighted-average exchange rates during the period. Equity transactions are translated at historical exchange rates. Foreign currency transaction gains and losses are recorded in other income (expense).

Research and Development

Research and Development — Research and development expenses include payroll, employee benefits and other expenses associated with product development.

Capitalized Software Development Costs

Capitalized Software Development Costs — Certain payroll and stock compensation costs incurred to develop functionality for the Company’s software platform, as well as certain upgrades and enhancements that are expected to result in increased functionality are capitalized. The costs incurred in the preliminary stages of development are expensed as incurred. Once an application has reached the development stage, certain internal costs are capitalized until the software is substantially complete and ready for its intended use. Capitalized software development costs are amortized on a straight-line basis over their estimated useful life of two years. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets.

Capitalized software development costs consisted of the following:

	December 31,
	2014			2013
	(in thousands)
Gross capitalized software development costs	$	14,219		$	9,351
Accumulated amortization		(9,786	)		(5,872	)
Capitalized software development costs, net	$	4,433		$	3,479

The Company capitalized software development costs of $4.9 million in 2014, $3.7 million in 2013, and $2.4 million in 2012. Stock-based compensation costs included in capitalized software were $235 thousand in 2014, $273 thousand in 2013, and $100 thousand in 2012.

Amortization of capitalized software development costs was $3.9 million in 2014, $2.6 million in 2013, and $1.5 million in 2012. Amortization expense is included in cost of revenue in the consolidated statements of operations.

Income Taxes

Income Taxes — Deferred tax assets and liabilities are recognized for the differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities using tax rates expected to be in effect in the years in which the differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will not be realized.

The Company provides reserves for potential payments of tax to various tax authorities related to uncertain tax positions based on a determination of whether and how much of a tax benefit taken by the Company in its tax filings or positions is more likely than not to be realized following resolution of any potential contingencies present related to the tax benefit. Potential interest and penalties associated with such uncertain tax positions are recorded as a component of income tax expense.

Stock-Based Compensation

Stock-Based Compensation —The Company accounts for all stock options and awards granted to employees and nonemployees using a fair value method. Stock-based compensation is recognized as an expense and is measured at the fair value of the award. The measurement date for employee awards is generally the date of the grant. The measurement date for nonemployee awards is generally the date the options vest. Stock-based compensation costs are recognized as expense over the requisite service period, which is generally the vesting period for awards, on a straight-line basis for awards with only a service condition, and using the graded-method for awards with both a performance and service that were granted prior to our IPO, and on a straight-line basis for the awards that were granted following our IPO.

Recent Accounting Pronouncements

Recent Accounting Pronouncements—In May 2014, the Financial Accounting Standards Board issued updated guidance and disclosure requirements for recognizing revenue. The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance will be effective for the Company on January 1, 2017 and may be applied retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is evaluating the potential impact of adopting this new accounting guidance.

In June 2014, the Financial Accounting Standards Board issued a standards update on accounting for share-based payments when the terms of the award provide that a performance target could be achieved after a requisite service period. The standard is effective beginning January 1, 2016, with early adoption permitted. We do not expect it to have a material impact on our consolidated financial position, results of operations or cash flows.

1. Organization and Operations

HubSpot, Inc. (the “Company”), was formed as a limited liability company in Delaware on April 4, 2005. The Company converted to a Delaware corporation on June 7, 2007. The Company provides a cloud-based inbound marketing and sales platform which features integrated applications to help businesses attract visitors to their websites, convert visitors into leads, close leads into customers and delight customers so they become promoters of those businesses. These integrated applications include social media, search engine optimization, blogging, website content management, marketing automation, email, CRM, analytics, and reporting.

The Company is headquartered in Cambridge, Massachusetts, and has wholly-owned subsidiaries in Dublin, Ireland, which commenced operations in January of 2013 and in Sydney, Australia, which commenced operations in August of 2014.

On September 25, 2014, the Company’s Board of Directors and stockholders approved a 1-for-3 reverse stock split of the Company’s common stock. All references made to share or per share amounts in the accompanying consolidated financial statements and applicable disclosures have been retroactively adjusted to reflect the Stock Split. See Note 10 for additional information about the Stock Split.

On October 15, 2014, the Company closed its initial public offering (“IPO”) whereby 5,750,000 shares of common stock were sold to the public, including the underwriters’ overallotment option of 750,000 shares of common stock, at a price of $25.00 per share. The Company received aggregate proceeds of approximately $133.7 million from the IPO, net of underwriters’ discounts and commissions, but before deduction of offering expenses of approximately $3.1 million. Upon the closing of the IPO, all shares of the Company’s outstanding convertible preferred stock automatically converted into 19,529,713 shares of common stock.

All restricted stock units, or RSUs, granted to employees prior to the IPO vest upon the satisfaction of both a service condition and a performance condition. The service condition for a majority of the RSUs is satisfied over a period of four years. The performance condition will be satisfied on the date that is six months following the Company’s IPO. No stock-based compensation expense was recognized for RSUs prior to the IPO because an IPO is not considered probable until it occurs. Upon completion of the Company’s IPO the Company began recording stock-based compensation expense based on the grant-date fair value of the RSUs using the accelerated attribution method for RSUs granted prior to its IPO and using the straight-line method for RSUs granted following its IPO, net of estimated forfeitures. The stock compensation expense associated with RSUs where the service condition had been met prior to the IPO was also recognized on the date of the IPO, using the accelerated attribution method.

Redeemable Convertible Preferred Stock

11. Redeemable Convertible Preferred Stock

Upon the closing of the IPO on October 15, 2014, all outstanding convertible preferred stock was converted into 19,529,713 shares of common stock on a one-to-three basis. No convertible preferred stock was outstanding as of December 31, 2014.

Prior to the IPO, the Company had authorized and issued Series A redeemable convertible preferred stock (“Series A”), Series B redeemable convertible preferred stock (“Series B”), Series C redeemable convertible preferred stock (“Series C”), Series D redeemable convertible preferred stock (“Series D”), Series D-1, and Series E redeemable convertible preferred stock (“Series E”) (collectively, “Preferred Stock”); which was classified as temporary equity.

The rights and privileges of Series A, Series B, Series C, Series D, Series D-1 and Series E (collectively, the “Preferred Stock”) were as follows:

Voting Rights—The holders of the Preferred Stock were entitled to vote on all matters and had the number of votes equal to the number of shares of common stock into which the Preferred Stock were then convertible.

Dividends—The holder of shares of Preferred Stock were entitled to receive dividends, when and if declared by the Company’s Board of Directors, out of any assets at the time legally available therefore, in preference to common stockholders. No dividends on convertible preferred stock were declared or paid by the Company through the date of the IPO.

Conversion—Prior to the IPO, each share of Preferred Stock was convertible at any time, at the option of the holder into shares of common stock, subject to the applicable conversion rate as determined by dividing the original issue price by the conversion price, with the exception of Series D-1. The issuance price was approximately $0.41 for Series A, $0.84 for Series B, $1.27 for Series C, $2.82 for Series D and $5.62 for Series E. The initial conversion prices were the same as the issuance prices and were adjusted to give effect to the Stock Split. Each share of Series D-1 could be converted as determined by dividing the Series D issuance price by the Series D conversion price (as adjusted for certain dilutive events).

Each share of Preferred Stock automatically converted into shares of common stock at the then-effective conversion rate on the date of the Company’s IPO.

Liquidation Preference—Prior to the IPO, the holders of the Preferred Stock had preferences over the holders of the Company’s common stock in the event of any voluntary or involuntary liquidation, dissolution, or winding-up of the Company, including a merger or consolidation. The amount that would have been paid per share was equal to the greater of approximately $0.41 for Series A, $0.84 for Series B, $1.27 for Series C, $2.82 for Series D, $1.77 for Series D-1 and $5.62 for Series E (as adjusted for certain dilutive events) plus any declared and unpaid dividends or such amount per share as would have been payable had all shares of the Preferred Stock been converted to common stock immediately prior to the liquidation event. Thereafter, any remaining assets available for distribution would have been distributed among the common stockholders.

Redemption—Prior to the IPO, upon written notice of 65% of the holders of Preferred Stock, the Preferred Stock was redeemable in three annual installments commencing 30 days after receipt by the Company at any time on or after March 3, 2020 for all series, except Series E. Series E was redeemable in one installment commencing 30 days after receipt by the Company at any time on or after March 3, 2020. The redemption price per share was approximately $0.41 for Series A, $0.84 for Series B, $1.27 for Series C, $2.82 for Series D, $1.77 for Series D-1 and $5.62 for Series E, plus any declared and unpaid dividends.

The Company was accreting Series A, Series B, Series C, Series D and Series E to their redemption value over the period from the date of issuance to March 3, 2020, such that the carrying amounts of the securities would equal the redemption amounts at the earliest redemption date. Upon the closing of the Company’s IPO all outstanding shares of preferred stock were accreted to their redemption value.

The following table contains the value of each class of Preferred Stock as of December 31, 2013, as well as the liquidation and redemption value at December 31, 2013:
