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 is referred to in this document as the Company’s Growth Platform, that enables businesses to grow better. The Company’s Growth Platform, comprised of Marketing Hub, Sales Hub, Service Hub, and a free customer relationship management system (“CRM”) features integrated applications and tools that enable businesses to create a cohesive and adaptable customer experience throughout the customer lifecycle. 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 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, 2020. 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 12, 2020. 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. On March 11, 2020, the World Health Organization, or WHO, classified the recent novel coronavirus, or COVID-19, as a global pandemic. The Company has assessed the impact of the COVID-19 pandemic and while the broader implications of COVID-19 on its results of operations and overall financial performance remain uncertain, the Company assessed the potential impact on its March 31, 2020 financial statements and determined there were no material adjustments necessary with respect to these consolidated financial statements. Given that the economic consequences of the COVID-19 pandemic have been exceptionally challenging for many customers, the Company has implemented certain changes to pricing and packaging, including reducing prices on certain products and offering certain product functionality free of charge. The Company also paid certain Solutions Partners two months of commissions in advance of them being earned. While revenue, customer retention, and earnings are relatively predictable under a subscription-based business model, the effect of the COVID-19 pandemic will not be fully reflected in the results of operations and overall financial performance of the Company until future periods given the current macro-economic uncertainty. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was signed into law by the United States. The CARES Act provides a substantial stimulus and assistance package intended to address the impact of the COVID-19 pandemic, including tax relief and government loans, grants and investments. The CARES Act did not have a material impact with respect to 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 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 previous guidance, Step 2 of the goodwill impairment test required 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 was recognized as goodwill impairment. Under the new guidance, 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 guidance was adopted effective January 1, 2020 and did not have a material impact on the consolidated financial statements. In June 2016, the FASB issued guidance that introduces a new methodology for accounting for credit losses on financial instruments. The guidance establishes a new forward-looking "expected loss model" that requires entities to estimate current expected credit losses on accounts receivable and financial instruments by using all practical and relevant information. The guidance was adopted effective January 1, 2020 and did not have a material impact on the consolidated financial statements. In December 2019, the FASB issued guidance simplifying the accounting for incomes taxes by removing (i) the exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items, (ii) the exception to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment, and (iii) the exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The guidance also improves consistent application of and simplifies GAAP for other areas of Topic 740, Income Taxes. The guidance was adopted effective January 1, 2020, using a prospective approach and did not have a material impact on the consolidated financial statements.

Revenue From Contract With Customer [Abstract]
Revenues	2. Revenues Disaggregation of Revenue The Company provides disaggregation of revenue based on geographic region (Note 13) and based on the subscription versus Deferred Revenue and Deferred Commission Expense 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. Deferred revenue during the three months ended March 31, 2020 increased by $8.2 million resulting from $207.2 million of additional invoicing and was offset by revenue recognized of $199.0 31, 2020, approximately $183.7 mill approximately 94% Additional contract liabilities of $1.4 million were The incremental direct costs of obtaining a contract, which primarily consist of sales commissions paid for new subscription contracts, are deferred and amortized on a straight-line basis over a period of approximately one to three years. The one to three-year period has been determined by taking into consideration the type of product sold, the commitment term of the customer contract, the nature of the Company’s technology development life-cycle, and an estimated customer relationship period. Sales commissions for upgrade contracts are deferred and amortized on a straight-line basis over the remaining estimated customer relationship period of the related customer. Deferred commission expense that will be recorded as expense during the succeeding 12-month period is recorded as current deferred commission expense, and the remaining portion is recorded as long-term deferred commission expense. Deferred commission expense during the three months ended March 31, 2020 increased by $0.8 million as a result of deferring incremental costs of obtaining a contract of $11.5

Earnings Per Share [Abstract]
Net Loss per Share	3. 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”), shares issued pursuant to the Employee Stock Purchase Plan (“ESPP”), and the Conversion Option and warrants of the 2022 Notes 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, 2020 2019 Net loss $ (17,716 ) $ (11,100 ) Weighted-average common shares outstanding — basic 43,275 40,568 Dilutive effect of share equivalents resulting from stock — — Weighted-average common shares, outstanding — diluted 43,275 40,568 Net loss per share, basic and diluted $ (0.41 ) $ (0.27 ) 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, shares issuable under the ESPP, and Conversion Option and warrants of the 2022 Notes 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, 2020 2019 (in thousands) Options to purchase common shares 1,401 1,734 RSUs 1,697 1,911 Conversion option and warrants of the 2022 Notes 3,093 2,830 ESPP — 8 The Company expects to settle the principal amount of the 2022 Notes (Note 8) in cash, and therefore, the Company uses the treasury stock method for calculating any potential dilutive effect of the Conversion Option on diluted net income per share, if applicable. The Conversion Option will have a dilutive impact on net income per share of common stock when the average market price of the Company’s common stock for a given period exceeds the conversion price of the 2022 Notes of $94.77 per share. In the first quarter of 2020, the Company settled $2 thousand of the principal balance of the 2022 Notes in cash.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	4. 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, 2020 and December 31, 2019: March 31, 2020 Level 1 Level 2 Level 3 Total (in thousands) Cash equivalents and investments: Money market funds $ 43,772 $ — $ — $ 43,772 Commercial paper — 83,100 — 83,100 Corporate bonds — 120,201 — 120,201 U.S. Treasury securities — 677,310 — 677,310 Restricted cash: Certificates of deposit — 552 — 552 Money market funds — 3,029 — 3,029 Total $ 43,772 $ 884,192 $ — $ 927,964 December 31, 2019 Level 1 Level 2 Level 3 Total (in thousands) Cash equivalents and investments: Money market funds $ 96,618 $ — $ — $ 96,618 Commercial paper — 87,185 — 87,185 Corporate bonds — 87,138 — 87,138 U.S. Treasury securities — 631,174 — 631,174 Restricted cash: Certificates of deposit — 5,816 — 5,816 Money market funds — 3,029 — 3,029 Total $ 96,618 $ 814,342 $ — $ 910,960 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, and restricted cash (within prepaid expenses and other current assets and other long-term assets) on the consolidated balance sheets. At March 31, 2020 and December 31, 2019, 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. As of March 31, 2020, the fair value of the 2022 Notes was $597.8 million. The fair value was determined based on the quoted price of the 2022 Notes in an inactive market on the last trading day of the reporting period and has been classified as Level 2 within the fair value hierarchy. 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 money market funds and certificates of deposit related to landlord guarantees for leased facilities. These restricted cash balances have been excluded from our cash and cash equivalents balance on our consolidated balance sheets. Strategic investments consist of non-controlling equity investments in privately held companies. The Company elected the measurement alternative for these investments without readily determinable fair values and for which the Company does not have the ability to exercise significant influence. These investments are accounted for under the cost method of accounting. Under the cost method of accounting, the non-marketable equity securities are carried 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 is recorded within the statement of operations. The Company holds $4.2 million of strategic investments without readily determinable fair values at March 31, 2020 and $4.4 million of strategic investments without readily determinable fair values at December 31, 2019. These investments are included in other assets on the consolidated balance sheets. For the three months ended March 31, 2020, the Company recorded an impairment of $250 thousand. The following tables summarize the composition of our short- and long-term investments at March 31, 2020 and December 31, 2019. March 31, 2020 Amortized Cost Unrealized Gains Unrealized Losses Aggregate Fair Value (in thousands) Commercial paper $ 83,100 $ — $ — $ 83,100 Corporate bonds 120,639 234 (672 ) 120,201 U.S. Treasury securities 600,897 1,422 (8 ) 602,311 Total $ 804,636 $ 1,656 $ (680 ) $ 805,612 December 31, 2019 Amortized Cost Unrealized Gains Unrealized Losses Aggregate Fair Value (in thousands) Commercial paper $ 77,214 $ — $ — $ 77,214 Corporate bonds 86,900 251 (13 ) 87,138 U.S. Treasury securities 581,066 207 (15 ) 581,258 Total $ 745,180 $ 458 $ (28 ) $ 745,610 For all of our securities for which the amortized cost basis was greater than the fair value at March 31, 2020, 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, 2020 and December 31, 2019 are as follows: March 31, 2020 December 31, 2019 Amortized Cost Basis Aggregate Fair Value Amortized Cost Basis Aggregate Fair Value (in thousands) (in thousands) Due within one year $ 737,992 $ 739,428 $ 691,556 $ 691,834 Due after 1 year through 2 years 66,644 66,184 53,624 53,776 Total $ 804,636 $ 805,612 $ 745,180 $ 745,610

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. 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 previous guidance, Step 2 of the goodwill impairment test required 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 was recognized as goodwill impairment. Under the new guidance, 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 guidance was adopted effective January 1, 2020 and did not have a material impact on the consolidated financial statements. In June 2016, the FASB issued guidance that introduces a new methodology for accounting for credit losses on financial instruments. The guidance establishes a new forward-looking "expected loss model" that requires entities to estimate current expected credit losses on accounts receivable and financial instruments by using all practical and relevant information. The guidance was adopted effective January 1, 2020 and did not have a material impact on the consolidated financial statements. In December 2019, the FASB issued guidance simplifying the accounting for incomes taxes by removing (i) the exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items, (ii) the exception to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment, and (iii) the exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The guidance also improves consistent application of and simplifies GAAP for other areas of Topic 740, Income Taxes. The guidance was adopted effective January 1, 2020, using a prospective approach and did not have a material impact on the consolidated financial statements.
Revenue	Revenues Disaggregation of Revenue The Company provides disaggregation of revenue based on geographic region (Note 13) and based on the subscription versus Deferred Revenue and Deferred Commission Expense 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. Deferred revenue during the three months ended March 31, 2020 increased by $8.2 million resulting from $207.2 million of additional invoicing and was offset by revenue recognized of $199.0 31, 2020, approximately $183.7 mill approximately 94% Additional contract liabilities of $1.4 million were The incremental direct costs of obtaining a contract, which primarily consist of sales commissions paid for new subscription contracts, are deferred and amortized on a straight-line basis over a period of approximately one to three years. The one to three-year period has been determined by taking into consideration the type of product sold, the commitment term of the customer contract, the nature of the Company’s technology development life-cycle, and an estimated customer relationship period. Sales commissions for upgrade contracts are deferred and amortized on a straight-line basis over the remaining estimated customer relationship period of the related customer. Deferred commission expense that will be recorded as expense during the succeeding 12-month period is recorded as current deferred commission expense, and the remaining portion is recorded as long-term deferred commission expense. Deferred commission expense during the three months ended March 31, 2020 increased by $0.8 million as a result of deferring incremental costs of obtaining a contract of $11.5
