Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying interim condensed consolidated financial statements are unaudited and have been prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP") for interim financial information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. These interim unaudited condensed consolidated financial statements include the accounts of the Company and all of its wholly-owned subsidiaries. The interim unaudited condensed consolidated financial statements have been prepared on a basis consistent with the annual consolidated financial statements and in the opinion of management, reflect all adjustments, including normal recurring adjustments, which are considered necessary to fairly state the Company’s financial position and results of operations as of and for the periods presented. All intercompany transactions and accounts have been eliminated. The results of operations for the interim periods should not be considered indicative of results for the full year or for any other future year or interim period. The year-end condensed balance sheet data was derived from audited financial statements but does not include all disclosures required by U.S. GAAP. Therefore, these interim unaudited condensed consolidated financial statements and accompanying footnotes should be read in conjunction with the Company’s annual consolidated financial statements and related footnotes included in its Annual Report on Form 10-K for the fiscal year ended January 31, 2023 (the “2023 Form 10-K”). Use of Estimates The preparation of the interim unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, assumptions and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Such estimates include, but are not limited to, revenue recognition, allowances for doubtful accounts, the incremental borrowing rate related to the Company’s lease liabilities, stock-based compensation, legal contingencies, fair value of acquired intangible assets and goodwill, useful lives of acquired intangible assets and property and equipment, fair value of non-marketable securities and accounting for income taxes. The Company bases these estimates on historical and anticipated results, trends and various other assumptions that it believes are reasonable under the circumstances, including assumptions as to future events. The global macroeconomic conditions, including slower economic growth, rising interest rates and inflation, continue to impact demand and supply for a broad variety of goods and services, including demand from the Company’s customers. Estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require the exercise of judgment. As of the date of issuance of these financial statements, the Company is not aware of any specific event or circumstance that would require the Company to update its estimates, assumptions and judgments or adjust the carrying value of its assets or liabilities. These estimates may change as new events occur and additional information is obtained and are recognized in the consolidated financial statements as soon as they become known. Actual results could differ from those estimates and any such differences may be material to the Company’s financial statements. Significant Accounting Policies There have been no changes to the Company’s significant accounting policies as described in the Company’s 2023 Form 10-K.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The following tables present information about the Company’s financial assets that have been measured at fair value on a recurring basis as of July 31, 2023 and January 31, 2023 and indicate the fair value hierarchy of the valuation inputs utilized to determine such fair value (in thousands): Fair Value Measurement as of July 31, 2023 Level 1 Level 2 Level 3 Total Financial Assets: Cash and cash equivalents: Money market funds $ 384,192 $ — $ — $ 384,192 Short-term investments: U.S. government treasury securities 1,293,926 — — 1,293,926 Total financial assets $ 1,678,118 $ — $ — $ 1,678,118 Fair Value Measurement as of January 31, 2023 Level 1 Level 2 Level 3 Total Financial Assets: Cash and cash equivalents: Money market funds $ 268,985 $ — $ — $ 268,985 Short-term investments: U.S. government treasury securities 1,380,804 — — 1,380,804 Total financial assets $ 1,649,789 $ — $ — $ 1,649,789 The Company utilized the market approach and Level 1 valuation inputs to value its money market mutual funds and U.S. government treasury securities because published net asset values were readily available. The following table summarizes the amortized cost and fair value of the Company’s short-term investments by remaining contractual maturity as of July 31, 2023 and January 31, 2023 (in thousands): July 31, 2023 January 31, 2023 Amortized Unrealized Fair Value Amortized Unrealized Fair Value Due within one year $ 838,948 $ (1,883) $ 837,065 $ 1,383,226 $ (2,421) $ 1,380,804 Due after one year and within three years 462,562 (5,701) 456,861 — — — Total short-term investments $ 1,301,510 $ (7,584) $ 1,293,926 $ 1,383,226 $ (2,421) $ 1,380,804 As of July 31, 2023 and January 31, 2023, unrealized losses on the Company’s U.S. government treasury securities were approximately $7.6 million and $2.4 million, respectively. These unrealized losses were caused by interest rate increases, which resulted in the decrease in market value of these securities. Because the decline in fair value is due to changes in interest rates and not credit quality, and because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be at maturity, the Company concluded that an allowance for credit losses was unnecessary for short-term investments as of July 31, 2023. Gross realized gains and losses were not material for each of the three and six month periods ended July 31, 2023 and 2022. There were no short-term investments in a continuous loss position for greater than twelve months. Convertible Senior Notes The Company measures the fair value of its outstanding convertible senior notes on a quarterly basis for disclosure purposes. The Company considers the fair value of its convertible senior notes at July 31, 2023 to be a Level 2 measurement due to limited trading activity of the convertible senior notes. Refer to Note 5, Convertible Senior Notes , for further details. Non-marketable Securities As of July 31, 2023 and January 31, 2023, the total amount of non-marketable equity and debt securities included in other assets on the Company’s condensed consolidated balance sheets were $13.1 million and $9.8 million, respectively. During the six months ended July 31, 2023 and 2022, the Company invested an additional $2.1 million and $1.1 million, respectively, of its cash in non-marketable equity securities. The Company recognized net unrealized gains on certain of these non-marketable securities of $1.3 million and $1.7 million during the six months ended July 31, 2023 and 2022, respectively. The Company recognized unrealized losses on certain of these non-marketable securities of $0.9 million and $0.1 million during the three months ended July 31, 2023 and 2022, respectively. Refer to Note 2, Summary of Significant Accounting Policies , in the Notes to Consolidated Financial Statements included in Part II, Item 8 of the Company’s 2023 Form 10-K for further information. The Company considers these assets as Level 3 within the fair value hierarchy. The estimation of fair value for these investments is inherently complex due to the lack of readily available market data and inherent lack of liquidity and requires the Company’s judgment and the use of significant unobservable inputs in an inactive market. In addition, the determination of whether an orderly transaction is for the identical or a similar investment requires significant management judgment, including understanding the differences in the rights and obligations of the investments, the extent to which those differences would affect the fair values of those investments and the stage of operational development of the entities.

Debt Disclosure [Abstract]
Convertible Senior Notes	Convertible Senior Notes The net carrying amounts of the Company’s 2026 Notes (as defined herein) were as follows for the periods presented (in thousands): July 31, 2023 January 31, 2023 Principal $ 1,149,972 $ 1,149,972 Unamortized debt issuance costs (8,398) (10,092) Net carrying amount $ 1,141,574 $ 1,139,880 As of July 31, 2023, the estimated fair value (Level 2) of the outstanding 2026 Notes, which is utilized solely for disclosure purposes, was approximately $2.3 billion. The fair value was determined based on the closing trading price per $100 of the 2026 Notes as of the last day of trading for the period. The fair value of the 2026 Notes is primarily affected by the trading price of the Company’s common stock and market interest rates. In January 2020, the Company issued $1.0 billion aggregate principal amount of 0.25% convertible senior notes due 2026 in a private placement and, also in January 2020, the Company issued an additional $150.0 million aggregate principal amount of convertible senior notes pursuant to the exercise in full of the initial purchasers’ option to purchase additional convertible senior notes (collectively, the “2026 Notes”). The 2026 Notes are senior unsecured obligations of the Company and interest is payable semiannually in arrears on July 15 and January 15 of each year, beginning on July 15, 2020, at a rate of 0.25% per year. The 2026 Notes will mature on January 15, 2026, unless earlier converted, redeemed or repurchased. The total net proceeds from the offering, after deducting initial purchase discounts and estimated debt issuance costs, were approximately $1.13 billion. Refer to Note 6, Convertible Senior Notes , in the Notes to Consolidated Financial Statements included in Part II, Item 8 of the Company’s 2023 Form 10-K for further information on the 2026 Notes. During the three months ended July 31, 2023, the conditional conversion feature of the 2026 Notes was triggered as the last reported sale price of the Company's common stock was more than or equal to 130% of the conversion price for at least 20 trading days in the period of 30 consecutive trading days ending on July 31, 2023 (the last trading day of the fiscal quarter) and therefore the 2026 Notes are convertible, in whole or in part, from August 1, 2023 through October 31, 2023. Whether the 2026 Notes will be convertible following such period will depend on the continued satisfaction of this condition or another conversion condition in the future. Capped Calls In connection with the pricing of the issuance of our convertible notes due June 15, 2024 (the “2024 Notes”) and the 2026 Notes, the Company entered into privately negotiated capped call transactions with certain counterparties (the “Capped Calls”). The Capped Calls associated with the 2024 Notes each have an initial strike price of approximately $68.15 per share, subject to certain adjustments, which corresponded to the initial conversion price of the 2024 Notes. These Capped Calls have initial cap prices of $106.90 per share, subject to certain adjustments. The Capped Calls associated with the 2026 Notes each have an initial strike price of approximately $211.20 per share, subject to certain adjustments, which corresponds to the initial conversion price of the 2026 Notes. These Capped Calls have initial cap prices of $296.42 per share, subject to certain adjustments. The Company did not unwind any of its Capped Calls through July 31, 2023. Refer to Note 6, Convertible Senior Notes , in the Notes to Consolidated Financial Statements included in Part II, Item 8 of the Company’s 2023 Form 10-K for further information on the Capped Calls and the 2024 Notes.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Non-cancelable Material Commitments During the six months ended July 31, 2023, other than certain non-cancelable operating leases described in Note 6, Leases , there have been no material changes outside the ordinary course of business t o the Company’s contractual obligations and commitments from those disclosed in the 2023 Form 10-K. Legal Matters The Company investigates all claims, litigation and other legal matters as they arise. From time to time, the Company has become involved in claims, litigation and other legal matters arising in the ordinary course of business, including intellectual property, labor and employment and breach of contract claims. For example, on March 12, 2019, Realtime Data LLC (“Realtime”) filed a lawsuit against the Company in the United States District Court for the District of Delaware alleging that the Company is infringing three U.S. patents that it holds. On May 4, 2021, the District Court granted certain defendants' motion to dismiss without prejudice. Realtime filed an amended complaint on May 18, 2021, which the District Court dismissed on August 23, 2021. On August 25, 2021, Realtime filed a notice of appeal of the Delaware District Court’s order. The oral argument took place before the U.S. Court of Appeals for the Federal Circuit on February 10, 2023. On August 2, 2023, the U.S. Court of Appeals for the Federal Circuit issued an opinion affirming the District Court's order in favor of the Company. The Company believes the Federal Circuit correctly decided the matter, and it intends to continue to vigorously defend itself in the event of future appellate proceedings and any other potential future claims. Although claims and litigation are inherently unpredictable, as of July 31, 2023, the Company does not believe that any legal matters, if determined adversely to the Company, would individually or taken together have a material adverse effect on its business, financial position, results of operations or cash flows. The Company accrues estimates for resolution of legal and other contingencies when losses are probable and estimable. 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. Indemnification The Company enters into indemnification provisions under its agreements with other companies in the ordinary course of business, including business partners, landlords, contractors and parties performing its research and development. Pursuant to these arrangements, the Company agrees to indemnify, hold harmless and reimburse the indemnified party for certain losses suffered or incurred by the indemnified party as a result of the Company’s activities. The terms of these indemnification agreements are generally perpetual. The maximum potential amount of future payments the Company could be required to make under these agreements is not determinable. To date, the Company has not incurred material costs as a result of such commitments. The Company maintains commercial general liability insurance and product liability insurance to offset certain of the Company’s potential liabilities under these indemnification provisions. The Company has entered into indemnification agreements with each of its directors and executive officers. These agreements require the Company to indemnify such individuals, to the fullest extent permitted by Delaware law, for certain liabilities to which they may become subject as a result of their affiliation with the Company.

Revenues [Abstract]
Revenue	Revenue Disaggregation of Revenue Based on the information provided to and reviewed by the Company’s Chief Executive Officer, its Chief Operating Decision Maker, the Company believes that the nature, amount, timing and uncertainty of its revenue and cash flows and how they are affected by economic factors is most appropriately depicted through the Company’s primary geographical markets and subscription product categories. The Company’s primary geographical markets are North and South America (“Americas”); Europe, Middle East and Africa (“EMEA”); and Asia Pacific. The Company also disaggregates its subscription products between its MongoDB Atlas-related offerings and other subscription products, which include MongoDB Enterprise Advanced. The following table presents the Company’s revenues disaggregated by primary geographical markets, subscription product categories and services (in thousands): Three Months Ended July 31, Six Months Ended July 31, 2023 2022 2023 2022 Primary geographical markets: Americas $ 253,485 $ 185,796 $ 475,831 $ 359,852 EMEA 113,446 84,627 218,569 166,596 Asia Pacific 56,860 33,237 97,671 62,659 Total $ 423,791 $ 303,660 $ 792,071 $ 589,107 Subscription product categories and services: MongoDB Atlas-related $ 267,258 $ 193,354 $ 505,014 $ 363,349 Other subscription 142,076 98,253 259,034 202,839 Services 14,457 12,053 28,023 22,919 Total $ 423,791 $ 303,660 $ 792,071 $ 589,107 Customers located in the United States accounted for 53% and 54% of total revenue for the three and six months ended July 31, 2023, respectively, and 55% of total revenue for both the three and six months ended July 31, 2022. No other country accounted for 10% or more of revenue for the periods presented. Contract Liabilities The Company’s contract liabilities are recorded as deferred revenue in the Company’s condensed consolidated balance sheet and consist of customer invoices issued or payments received in advance of revenues being recognized from the Company’s subscription and services contracts. Deferred revenue, including current and non-current balances, as of July 31, 2023 and January 31, 2023 was $368.6 million and $460.3 million, respectively. Approximately 37% and 36% of the total revenue recognized for the six months ended July 31, 2023 and 2022, respectively, was from deferred revenue at the beginning of each respective period. Remaining Performance Obligations Remaining performance obligations represent the aggregate amount of the transaction price in contracts allocated to performance obligations not delivered, or partially undelivered, as of the end of the reporting period. Remaining performance obligations include unearned revenue, multi-year contracts with future installment payments and certain unfulfilled orders against accepted customer contracts at the end of any given period. As of July 31, 2023, the aggregate transaction price allocated to remaining performance obligations was $481.5 million. Approximately 56% is expected to be recognized as revenue over the next 12 months and the remainder thereafter. The Company applies the practical expedient to omit disclosure with respect to the amount of the transaction price allocated to remaining performance obligations if the related contract has a total duration of 12 months or less. Unbilled Receivables Revenue recognized in excess of invoiced amounts creates an unbilled receivable, which represents the Company’s unconditional right to consideration in exchange for goods or services that the Company has transferred to the customer. Unbilled receivables are recorded as part of accounts receivable, net in the Company’s condensed consolidated balance sheets. As of July 31, 2023 and January 31, 2023, unbilled receivables were $12.7 million and $9.7 million, respectively. Allowance for Doubtful Accounts The Company considers expectations of forward-looking losses, in addition to historical loss rates, to estimate its allowance for doubtful accounts on its accounts receivable. The following is a summary of the changes in the Company’s allowance for doubtful accounts (in thousands): Allowance for Doubtful Accounts Balance at January 31, 2023 $ 6,362 Provision 4,820 Recoveries/write-offs (4,017) Balance as of July 31, 2023 $ 7,165 Costs Capitalized to Obtain Contracts with Customers Deferred commissions were $256.9 million and $252.4 million as of July 31, 2023 and January 31, 2023, respectively. Amortization expense with respect to deferred commissions, which is included in sales and marketing expense in the Company’s interim unaudited condensed consolidated statements of operations, was $23.6 million and $46.7 million for the three and six months ended July 31, 2023, respectively, and $18.9 million and $36.5 million for the three and six months ended July 31, 2022, respectively. There was no impairment loss in relation to the costs capitalized for the periods presented.

Share-Based Payment Arrangement [Abstract]
Equity Incentive Plans and Employee Stock Purchase Plan	Equity Incentive Plan and Employee Stock Purchase Plan Equity Incentive Plan The Company adopted the 2008 Stock Incentive Plan (as amended, the “2008 Plan”) and the 2016 Equity Incentive Plan (as amended the “2016 Plan”), primarily for the purpose of granting stock-based awards to eligible employees, directors and consultants, including stock options, restricted stock units (“RSUs”) and other stock-based awards. With the establishment of the 2016 Plan in December 2016, all shares available for grant under the 2008 Plan were transferred to the 2016 Plan. The Company no longer grants any stock-based awards under the 2008 Plan and any shares underlying stock options canceled under the 2008 Plan will be automatically transferred to the 2016 Plan. Stock Options The 2016 Plan provides for the issuance of incentive stock options to eligible employees and non-statutory stock options to eligible employees, directors or consultants. The Company’s Board of Directors, or a committee thereof, determines the vesting schedule for all equity awards. Stock option awards generally vest over a period of four years with 25% vesting on the one-year anniversary of the award and the remainder vesting monthly over the next 36 months of the grantee’s service to the Company. There were no stock options granted during the six months ended July 31, 2023. The following table summarizes stock option activity for the six months ended July 31, 2023 (in thousands, except share and per share data and years): Shares Weighted-Average Weighted- Average Aggregate Balance - January 31, 2023 1,789,813 $ 7.60 3.3 $ 313,980 Stock options exercised (479,190) 7.32 Stock options forfeited and expired (547) 5.81 Balance - July 31, 2023 1,310,076 $ 7.71 2.9 $ 544,588 Vested and exercisable - January 31, 2023 1,789,813 $ 7.60 3.3 $ 313,980 Vested and exercisable - July 31, 2023 1,310,076 $ 7.71 2.9 $ 544,588 Restricted Stock Units The 2016 Plan provides for the issuance of RSUs to eligible employees, directors and consultants. RSUs granted to new employees generally vest over a period of four years with 25% vesting on the one-year anniversary of the vesting start date and the remainder vesting quarterly over the next 12 quarters, subject to the grantee’s continued service to the Company. RSUs granted to existing employees generally vest quarterly over a period of four years, subject to the grantee’s continued service to the Company. The following table summarizes RSU activity for the six months ended July 31, 2023: Shares Weighted-Average Grant Date Fair Value per RSU Unvested - January 31, 2023 3,480,206 $ 288.58 RSUs granted 1,698,268 225.66 RSUs vested (820,110) 254.73 RSUs forfeited and canceled (308,660) 288.06 Unvested - July 31, 2023 4,049,704 $ 279.87 2017 Employee Stock Purchase Plan In October 2017, the Company’s Board of Directors adopted, and stockholders approved, the 2017 Employee Stock Purchase Plan (the “2017 ESPP”). Subject to any plan limitations, the 2017 ESPP allows eligible employees to contribute, normally through payroll deductions, up to 15% of their earnings for the purchase of the Company’s common stock at a discounted price per share. In June 2023, the Company issued 114,508 shares of its common stock under the 2017 ESPP. The Company’s current offering period began on June 16, 2023 and is expected to end December 15, 2023.

Net Loss Per Share

Net Loss Per Share	6 Months Ended

Earnings Per Share [Abstract]
Net Loss Per Share	Net Loss Per ShareThe Company calculates basic net loss per share by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period, less shares subject to repurchase. Diluted net loss per share is computed by giving effect to all potentially dilutive common shares outstanding for the period, including stock options, restricted stock units and shares underlying the conversion option of the convertible senior notes. Basic and diluted net loss per share was the same for each period presented, as the inclusion of all potential common shares outstanding would have been anti-dilutive due to the net loss reported for each period presented. The following table sets forth the computation of basic and diluted net loss per share (in thousands, except share and per share data): Three Months Ended July 31, Six Months Ended July 31, 2023 2022 2023 2022 Numerator: Net loss $ (37,597) $ (118,865) $ (91,843) $ (196,159) Denominator: Weighted-average shares used to compute net loss per share, basic and diluted 70,874,117 68,334,464 70,531,581 68,025,687 Net loss per share, basic and diluted $ (0.53) $ (1.74) $ (1.30) $ (2.88) In connection with the issuance of the 2024 Notes and 2026 Notes, the Company entered into Capped Calls, which were not included for purposes of calculating the number of diluted shares outstanding, as their effect would have been anti-dilutive. The Capped Calls are expected to partially offset the potential dilution to the Company’s common stock upon any conversion of the 2024 Notes and the 2026 Notes. The Company has not exercised any of its Capped Calls as of July 31, 2023. The following weighted-average outstanding potentially dilutive shares of common stock were excluded from the computation of diluted net loss per share for the periods presented because the impact of including them would have been anti-dilutive: Three Months Ended July 31, Six Months Ended July 31, 2023 2022 2023 2022 Stock options pursuant to the 2016 Equity Incentive Plan 448,447 584,405 476,450 602,856 Stock options pursuant to the 2008 Stock Incentive Plan 988,792 1,666,919 1,070,891 1,751,927 Unvested restricted stock units 4,498,170 3,851,114 4,276,548 3,763,435 Unvested executive PSUs 254,321 81,557 254,321 81,557 Shares underlying the conversion option of the 2026 Notes 5,445,002 5,445,050 5,445,002 5,445,059 Total 11,634,732 11,629,045 11,523,212 11,644,834

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded a provision for income taxes of $3.6 million and $6.1 million for the three and six months ended July 31, 2023, respectively, and $3.0 million and $4.2 million for the three and six months ended July 31, 2022, respectively. The provisions recorded during each of the three and six months ended July 31, 2023 and 2022 were driven by the increase in global income and the associated foreign taxes as the Company continues its global expansion. The calculation of income taxes was based upon the estimated annual effective tax rates for the year applied to the jurisdictional mix of current period loss before tax plus the tax effect of any significant unusual items, discrete events or changes in tax law. The Company regularly assesses the need for a valuation allowance against its deferred tax assets. In making that assessment, the Company considers both positive and negative evidence related to the likelihood of realization of the deferred tax assets to determine, based on the weight of available evidence, whether it is more likely than not that some or all of the deferred tax assets will not be realized. The Company has maintained a valuation allowance on U.S., U.K. and Ireland net deferred tax assets, as it is more likely than not that some or all of the deferred tax assets will not be realized. The Company assesses uncertain tax positions in accordance with ASC 740-10, Accounting for Uncertainties in Tax . As of January 31, 2023, the Company’s net unrecognized tax benefits totaled $29.3 million, which would have no impact on the Company’s effective tax rate if recognized. The Company continues to monitor and interpret the impact of proposed and enacted global tax legislation. To date, globally enacted tax legislation has not materially impacted income tax expense of the financial statements due to the presence of net operating losses and full valuation allowances within the Company’s two most significant tax jurisdictions, the United States and Ireland.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jul. 31, 2023
Accounting Policies [Abstract]
Basis of Presentation	The accompanying interim condensed consolidated financial statements are unaudited and have been prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP") for interim financial information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. These interim unaudited condensed consolidated financial statements include the accounts of the Company and all of its wholly-owned subsidiaries. The interim unaudited condensed consolidated financial statements have been prepared on a basis consistent with the annual consolidated financial statements and in the opinion of management, reflect all adjustments, including normal recurring adjustments, which are considered necessary to fairly state the Company’s financial position and results of operations as of and for the periods presented. All intercompany transactions and accounts have been eliminated. The results of operations for the interim periods should not be considered indicative of results for the full year or for any other future year or interim period. The year-end condensed balance sheet data was derived from audited financial statements but does not include all disclosures required by U.S. GAAP. Therefore, these interim unaudited condensed consolidated financial statements and accompanying footnotes should be read in conjunction with the Company’s annual consolidated financial statements and related footnotes included in its Annual Report on Form 10-K for the fiscal year ended January 31, 2023 (the “2023 Form 10-K”).
Use of Estimates	The preparation of the interim unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, assumptions and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Such estimates include, but are not limited to, revenue recognition, allowances for doubtful accounts, the incremental borrowing rate related to the Company’s lease liabilities, stock-based compensation, legal contingencies, fair value of acquired intangible assets and goodwill, useful lives of acquired intangible assets and property and equipment, fair value of non-marketable securities and accounting for income taxes. The Company bases these estimates on historical and anticipated results, trends and various other assumptions that it believes are reasonable under the circumstances, including assumptions as to future events. The global macroeconomic conditions, including slower economic growth, rising interest rates and inflation, continue to impact demand and supply for a broad variety of goods and services, including demand from the Company’s customers. Estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require the exercise of judgment. As of the date of issuance of these financial statements, the Company is not aware of any specific event or circumstance that would require the Company to update its estimates, assumptions and judgments or adjust the carrying value of its assets or liabilities. These estimates may change as new events occur and additional information is obtained and are recognized in the consolidated financial statements as soon as they become known. Actual results could differ from those estimates and any such differences may be material to the Company’s financial statements.
Net Loss per Share	The Company calculates basic net loss per share by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period, less shares subject to repurchase. Diluted net loss per share is computed by giving effect to all potentially dilutive common shares outstanding for the period, including stock options, restricted stock units and shares underlying the conversion option of the convertible senior notes. Basic and diluted net loss per share was the same for each period presented, as the inclusion of all potential common shares outstanding would have been anti-dilutive due to the net loss reported for each period presented.
