Accounting Policies [Abstract]
Organization and Operations	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 2013, in Sydney, Australia, which commenced operations in August 2014, in Singapore, which commenced operations in October 2015, and in Tokyo, Japan, which commenced operations in July 2016. Additionally, the Company has announced that it will open an office in Berlin, Germany during the second half of 2017. 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, 2016, 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, 2017. 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 February16, 2017. 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 certain aspects of share-based payments to employee described within the Recent Accounting Pronouncements 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. The Company adopted updated guidance related to certain aspects of share-based payments to employees. The guidance requires the recognition of the income tax effects of awards in the income statement when the awards vest or are settled, thus eliminating additional paid-in capital pools. In addition, the Company changed its policy election to account for forfeitures as they occur rather than on an estimated basis. The change in the policy election related to forfeitures resulted in the Company reclassifying $453 thousand from additional paid-in capital to accumulative deficit for the net cumulative-effect adjustment in stock compensation expense related to prior periods. In January 2017, the Financial Accounting Standards Board (“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. We do not believe the adoption of this guidance will have a material impact on our 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. As of March 31, 2017, we had $4.9 million in restricted cash. The new standard is effective beginning in the first quarter of 2018, with early adoption permitted. We do not believe the adoption of this guidance will have a material impact on our consolidated financial statements. 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 is currently evaluating the impact of this guidance 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. In July 2015, the FASB approved the deferral of the new standard's effective date by one year. The new standard now is effective for annual reporting periods beginning January 1, 2018. The FASB will permit companies to adopt the new standard early, but not before the original effective date of January 1, 2017. The Company will adopt the standard on January 1, 2018, and currently anticipates adopting the standard using the modified retrospective method,

Earnings Per Share [Abstract]
Net Loss per Share	2. Net Loss per Share Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding for the period. Diluted net loss per share 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, restricted stock units (“RSUs”), and Employee Stock Purchase Plan (“ESPP”) are considered to be potential common stock equivalents. A reconciliation of the denominator used in the calculation of basic and diluted net loss per share is as follows: Three Months Ended March 31, 2017 2016 Net loss $ (8,075 ) $ (10,154 ) Weighted-average common shares outstanding — basic 36,205 34,692 Dilutive effect of share equivalents resulting from stock options, RSUs, and ESPP — — Weighted-average common shares, outstanding — diluted 36,205 34,692 Net loss per share, basic and diluted $ (0.22 ) $ (0.29 ) Additionally, since the Company incurred net losses for each of the periods presented, diluted net loss per share is the same as basic net loss per share. The Company’s outstanding stock options, RSUs, and ESPP were not included in the calculation of diluted net loss per share as the effect would be anti-dilutive. The following table contains all potentially dilutive common stock equivalents. As of March 31, 2017 2016 (in thousands) Options to purchase common shares 2,561 3,200 RSUs 2,013 1,785 ESPP 3 —

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 following table details the fair value measurements within the fair value hierarchy of the Company’s financial assets and liabilities at March 31, 2017 and December 31, 2016. March 31, 2017 Level 1 Level 2 Level 3 Total (in thousands) Cash equivalents and investments: Money market funds $ 32,128 $ — $ — $ 32,128 Commercial paper — 11,962 — 11,962 Corporate bonds — 67,901 — 67,901 U.S. government agency obligations — 10,984 — 10,984 Restricted cash: Certificates of deposit — 4,940 — 4,940 Total $ 32,128 $ 95,787 $ — $ 127,915 December 31, 2016 Level 1 Level 2 Level 3 Total (in thousands) Cash equivalents and investments: Money market funds $ 32,260 $ — $ — $ 32,260 Commercial paper — 12,439 — 12,439 Corporate bonds — 66,947 — 66,947 U.S. government agency obligations — 10,980 — 10,980 Total $ 32,260 $ 90,366 $ — $ 122,626 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 and such instruments are classified as Level 1 and are included in cash and cash equivalents on the consolidated balance sheets. At March 31, 2017 and December 31, 2016, our Level 2 securities were priced by pricing vendors. These pricing vendors utilize the most recent observable market information in pricing these securities or, if specific prices are not available for these securities, use other observable inputs like market transactions involving identical or comparable securities. For certain other financial instruments, including accounts receivable, accounts payable, capital leases and other current liabilities, the carrying amounts approximate their fair value due to the relatively short maturity of these balances. Restricted cash is comprised of certificates of deposit related to landlord guarantees for our leased facilities. These restricted cash balances have been excluded from our cash and cash equivalents balance on our consolidated balance sheets. The following tables summarize the composition of our short- and long-term investments at March 31, 2017 and December 31, 2016. March 31, 2017 Amortized Cost Unrealized Gains Unrealized Losses Aggregate Fair Value (in thousands) Commercial paper $ 11,967 $ — $ (5 ) $ 11,962 Corporate bonds 68,034 3 (136 ) 67,901 U.S. government agency obligations 10,999 1 (16 ) 10,984 Total $ 91,000 $ 4 $ (157 ) $ 90,847 December 31, 2016 Amortized Cost Unrealized Gains Unrealized Losses Aggregate Fair Value (in thousands) Commercial paper $ 12,446 $ — $ (7 ) $ 12,439 Corporate bonds 67,126 — (179 ) 66,947 U.S. government agency obligations 10,998 — (18 ) 10,980 Total $ 90,570 $ — $ (204 ) $ 90,366 For all of our securities for which the amortized cost basis was greater than the fair value at March 31, 2017, the Company has concluded that there is no plan to sell the security nor is it more likely than not that the Company would be required to sell the security before its anticipated recovery. In making the determination as to whether the unrealized loss is other-than-temporary, the Company considered the length of time and extent the investment has been in an unrealized loss position, the financial condition and near-term prospects of the issuers, the issuers’ credit rating and the time to maturity. Contractual Maturities The contractual maturities of short-term and long-term investments held at March 31, 2017 and December 31, 2016 are as follows: March 31, 2017 December 31, 2016 Amortized Cost Basis Aggregate Fair Value Amortized Cost Basis Aggregate Fair Value (in thousands) (in thousands) Due within one year $ 53,059 $ 53,001 $ 54,694 $ 54,648 Due after 1 year through 2 years 37,941 37,846 35,876 35,718 Total $ 91,000 $ 90,847 $ 90,570 $ 90,366

Segment Reporting [Abstract]
Segment Information and Geographic Data	9. Segment Information and Geographic Data 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. Revenue and long-lived assets by geographic region, based on the physical location of the operations recording the sale or the asset, are as follows: Revenues by geographical region: Three Months Ended March 31, 2017 2016 Americas $ 64,352 $ 48,777 Europe 13,844 8,499 Asia Pacific 4,056 1,684 Total $ 82,252 $ 58,960 Percentage of revenues generated outside of the Americas 22 % 17 % In the three months ended March 31, 2017, revenue derived from customers outside the United States (international) was approximately 30% of total revenue.

Accounting Policies [Abstract]
Recent Accounting Pronouncements	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. The Company adopted updated guidance related to certain aspects of share-based payments to employees. The guidance requires the recognition of the income tax effects of awards in the income statement when the awards vest or are settled, thus eliminating additional paid-in capital pools. In addition, the Company changed its policy election to account for forfeitures as they occur rather than on an estimated basis. The change in the policy election related to forfeitures resulted in the Company reclassifying $453 thousand from additional paid-in capital to accumulative deficit for the net cumulative-effect adjustment in stock compensation expense related to prior periods. In January 2017, the Financial Accounting Standards Board (“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. We do not believe the adoption of this guidance will have a material impact on our 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. As of March 31, 2017, we had $4.9 million in restricted cash. The new standard is effective beginning in the first quarter of 2018, with early adoption permitted. We do not believe the adoption of this guidance will have a material impact on our consolidated financial statements. 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 is currently evaluating the impact of this guidance 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. In July 2015, the FASB approved the deferral of the new standard's effective date by one year. The new standard now is effective for annual reporting periods beginning January 1, 2018. The FASB will permit companies to adopt the new standard early, but not before the original effective date of January 1, 2017. The Company will adopt the standard on January 1, 2018, and currently anticipates adopting the standard using the modified retrospective method,
