Accounting Policies [Abstract]
Organization and Operations	1. Organization and Operations HubSpot, Inc. (the “Company”) provides a cloud-based inbound marketing, sales and customer service 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, sales productivity, CRM, analytics, reporting, helpdesk, chat, and knowledge base. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) applicable to interim periods, under the rules and regulations of the United States Securities and Exchange Commission (“SEC”). In the opinion of management, the Company has prepared the accompanying unaudited consolidated financial statements on a basis substantially consistent with the audited consolidated financial statements of the Company as of and for the year ended December 31, 2017, and these consolidated financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the results of the interim periods presented. All intercompany balances and transactions have been eliminated in consolidation. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for any subsequent quarter or for the entire year ending December 31, 2018. The year-end balance sheet data was derived from audited financial statements, but this Form 10-Q does not include all disclosures required under GAAP. Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been omitted under the rules and regulations of the SEC. These interim financial statements should be read in conjunction with the audited consolidated financial statements and related notes contained in the Company’s Annual Report on Form 10-K filed with the SEC on February 13, 2018. There have been no changes in the Company’s significant accounting policies from those that were disclosed in the Company’s Annual Report on Form 10-K that have had a material impact on our consolidated financial statements and related notes, except the adoption of updated guidance related to revenue recognition and costs to obtain a contract with a customer as described within Note 2 of these consolidated financial statements. Recent Accounting Pronouncements Recent accounting standards not included below are not expected to have a material impact on our consolidated financial position and results of operations. In June 2018, the Financial Accounting Standards Board (“FASB”) issued guidance to expand the guidance for stock-based compensation, to include share-based payment transactions for acquiring goods and services from nonemployees. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact of this pronouncement on its consolidated financial statements. In January 2017, the FASB issued guidance simplifying the accounting for goodwill impairment by removing Step 2 of the goodwill impairment test. Under current guidance, Step 2 of the goodwill impairment test requires entities to calculate the implied fair value of goodwill in the same manner as the amount of goodwill recognized in a business combination by assigning the fair value of a reporting unit to all of the assets and liabilities of the reporting unit. The carrying value in excess of the implied fair value is recognized as goodwill impairment. Under the new standard, goodwill impairment is recognized based on Step 1 of the current guidance, which calculates the carrying value in excess of the reporting unit’s fair value. The new standard is effective beginning in January 2020, with early adoption permitted. The Company does not believe the adoption of this guidance will have a material impact on the consolidated financial statements. In November 2016, the FASB issued guidance related to the presentation of restricted cash within the statement of cash flows. The guidance requires entities to show the changes in cash, cash equivalents, and restricted cash in the statement of cash flows. Entities will no longer present transfers between cash and cash equivalents and restricted cash in the statement of cash flows. The Company adopted the updated guidance as of January 1, 2018. As a result of adopting this guidance cash and cash equivalents used in investing activities increased by $864 thousand and net increase in cash, cash equivalents, and restricted cash also increased by $864 thousand for the six months ended June 30, 2018. Cash and cash equivalents used in investing activities increased by $4.6 million and net increase in cash, cash equivalents, and restricted cash increased by $4.6 million for the six months ended June 30, 2017 in the consolidated statements of cash flows. In February 2016, the FASB issued guidance that requires lessees to recognize most leases on their balance sheets but record expenses on their income statements in a manner similar to current accounting. For lessors, the guidance modifies the classification criteria and the accounting for sales-type and direct financing leases. The guidance is effective in 2019 with early adoption permitted. The Company will adopt the standard on January 1, 2019. The Company has established a team that is continuing to assess the potential impacts of the standard on its consolidated financial statements and footnote disclosures. The Company currently believes the most significant changes will be related to the recognition of right-of-use assets and lease liabilities on its consolidated balance sheet for operating leases, which will increase total assets and total liabilities reported relative to such amounts prior to adoption. The guidance is required to be adopted using a modified retrospective approach. The Company is unable to quantify the impact at this time as the ultimate impact of adopting this new standard will depend on the total amount of lease commitments as of the adoption date. In January 2016, the FASB issued guidance that requires entities to measure equity instruments at fair value and recognize changes in fair value within the statement of operations. The Company adopted the updated guidance as of January 1, 2018. The guidance provides for electing a measurement alternative or defaulting to the fair value option for equity investments that do not have readily determinable fair values. The Company elected the measurement alternative for its equity investments in privately held companies, which are included in other assets in the accompanying consolidated balance sheets. These investments are measured at cost, less any impairment, plus or minus adjustments resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer, which will be recorded within the statement of operations. The adoption of this guidance did not have a material impact on the consolidated financial statements. In May 2014, the FASB 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. The standard also provides guidance on the recognition of costs related to obtaining customer contracts. The Company adopted the updated guidance as of January 1, 2018 using the modified retrospective transition method. See Note 2 of these consolidated financial statements for further details.
