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, 2022 (the “2022 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 period. 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 COVID-19 pandemic and global macroeconomic conditions, including 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, while also disrupting sales channels and marketing activities for an unknown period of time. 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 2022 Form 10-K.

Fair Value Disclosures [Abstract]

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 October 31, 2022 and January 31, 2022 and indicate the fair value hierarchy of the valuation inputs utilized to determine such fair value (in thousands):


	Fair Value Measurement as of October 31, 2022

Total financial assets	$	1,683,240	$	—	$	—	$	1,683,240

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 contractual maturity of all marketable securities was less than one year as of October 31, 2022 and January 31, 2022. As of October 31, 2022, unrealized losses on our U.S. government treasury securities were approximately $3.5 million. The fluctuations in market interest rates impact the unrealized losses on these securities. The Company intends to hold these securities to maturity and, as a result, does not expect to realize these losses in its financial statements. The Company concluded that an allowance for credit losses was unnecessary for short-term investments as of October 31, 2022. Gross realized gains and losses were not material for each of the three- and nine-month periods ended October 31, 2022 and 2021.

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 October 31, 2022 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 October 31, 2022 and January 31, 2022, the total amount of non-marketable equity and debt securities included in other assets on the Company’s condensed consolidated balance sheets were $9.3 million and $4.8 million, respectively. During the three and nine months ended October 31, 2022, the Company invested an additional $1.6 million and $2.7 million, respectively, of its cash in non-marketable equity securities. In addition, the Company recognized a gain on certain of these non-marketable securities of $1.7 million during the nine months ended October 31, 2022. No gain or loss was recognized during the nine months ended October 31, 2021. 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 2022 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.

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):


	October 31, 2022		January 31, 2022

Principal	$	1,149,979	$	1,149,988

Unamortized debt issuance costs	(10,937)		(13,467)
Net carrying amount	$	1,139,042	$	1,136,521

As of October 31, 2022, the estimated fair value (Level 2) of the outstanding 2026 Notes, which is utilized solely for disclosure purposes, was approximately $1.3 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 2022 Form 10-K for further information on the 2026 Notes.

During the three months ended October 31, 2022, the conditional conversion feature of the 2026 Notes was not triggered as the last reported sale price of the Company's common stock was not 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 October 31, 2022 (the last trading day of the fiscal quarter) and therefore the 2026 Notes are not convertible, in whole or in part, from November 1, 2022 through January 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.

During the three and nine months ended October 31, 2022, certain holders elected to redeem an immaterial aggregate principal amount of the 2026 Notes. The Company elected to settle the redemption through the issuance of common stock. The Company may elect to repay the 2026 Notes in cash, shares of the Company’s common stock or a combination of both cash and shares with respect to future conversions of the 2026 Notes.

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 October 31, 2022.

Refer to Note 6, Convertible Senior Notes, in the Notes to Consolidated Financial Statements included in Part II, Item 8 of the Company’s 2022 Form 10-K for further information on the Capped Calls and the 2024 Notes.

Commitments and Contingencies	9 Months Ended
Commitments and Contingencies	Oct. 31, 2022
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Non-cancelable Material Commitments During the nine months ended October 31, 2022, other than certain non-cancelable operating leases described in Note 6, Leases, there have been no material changes outside the ordinary course of business to the Company’s contractual obligations and commitments from those disclosed in the 2022 Form 10-K. Legal Matters 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 claims, labor and employment claims 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: U.S. Patent No. 9,116,908, U.S. Patent No. 9,667,751 and U.S. Patent No. 8,933,825. On May 4, 2021, in a consolidated action that includes Realtime's case against MongoDB, the District Court granted certain defendants' motion to dismiss without prejudice, finding that the patents are invalid under 35 U.S.C. § 101. Realtime filed an amended complaint against the Company on May 18, 2021, and the Company moved to dismiss that amended complaint on June 29, 2021. On August 23, 2021, the District Court granted the Company's motion to dismiss. On August 25, 2021, Realtime filed a notice of appeal of the Delaware District Court’s order. Realtime filed its appellate brief on December 2, 2021 and the defendants (including MongoDB) filed a responsive brief on March 11, 2022. Realtime filed a reply brief on April 29, 2022. The oral argument has not yet been scheduled. The Company investigates all claims, litigation and other legal matters as they arise. Although claims and litigation are inherently unpredictable, as of October 31, 2022 and January 31, 2022, the Company is currently not aware of any matters that, 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. The Company has never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the Company believes the fair value of these agreements is not material. 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

Disaggregation of Revenue

Based on the information provided to and reviewed by the Company’s Chief Executive Officer (“CEO”), 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 October 31,				Nine Months Ended October 31,
	2022		2021		2022		2021
Primary geographical markets:
Americas	$	205,887	$	138,036	$	565,739	$	368,339
EMEA	91,023		66,183		257,619		178,490
Asia Pacific	36,711		22,674		99,370		60,459
Total	$	333,621	$	226,893	$	922,728	$	607,288

Subscription product categories and services:
MongoDB Atlas-related	$	211,378	$	131,123	$	574,727	$	336,390
Other subscription	109,378		86,748		312,217		247,432
Services	12,865		9,022		35,784		23,466
Total	$	333,621	$	226,893	$	922,728	$	607,288

Customers located in the United States accounted for 56% and 55% of total revenue for the three and nine months ended October 31, 2022, respectively, and 55% of total revenue for both the three and nine months ended October 31, 2021. 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 October 31, 2022 and January 31, 2022 was $398.2 million and $375.2 million, respectively. Approximately 30% of the total revenue recognized for both the nine months ended October 31, 2022 and 2021 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 October 31, 2022, the aggregate transaction price allocated to remaining performance obligations was $414.3 million. Approximately 64% 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 October 31, 2022 and January 31, 2022, unbilled receivables were $8.9 million and $6.1 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, 2022	$	4,966
Provision	3,809
Recoveries/write-offs	(3,318)
Balance as of October 31, 2022	$	5,457

Costs Capitalized to Obtain Contracts with Customers

Deferred commissions were $233.2 million and $203.3 million as of October 31, 2022 and January 31, 2022, respectively. Amortization expense with respect to deferred commissions, which is included in sales and marketing expense in the Company’s interim unaudited condensed consolidated statement of operations, was $20.5 million and $57.0 million for the three and nine months ended October 31, 2022, respectively, and $13.3 million and $33.5 million for the three and nine months ended October 31, 2021, respectively. There was no impairment loss in relation to the costs capitalized for the periods presented.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Equity Incentive Plans and Employee Stock Purchase Plan

9 Months Ended

Oct. 31, 2022

Share-Based Payment Arrangement [Abstract]

Equity Incentive Plans and Employee Stock Purchase Plan

2008 Stock Incentive Plan and 2016 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 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 employees and non-statutory stock options to 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 nine months ended October 31, 2022.

The following table summarizes stock option activity for the nine months ended October 31, 2022 (in thousands, except share and per share data and years):


	Shares	Weighted-Average Exercise Price Per Share		Weighted- Average Remaining Contractual Term (In Years)	Aggregate Intrinsic Value
Balance - January 31, 2022	2,591,894	$	7.46	3.9	$	1,030,680
Stock options exercised	(598,546)	7.25
Stock options forfeited and expired	(809)	5.72
Balance - October 31, 2022	1,992,539	$	7.52	3.5	$	349,716
Vested and exercisable - January 31, 2022	2,591,894	$	7.46	3.9	$	1,030,680
Vested and exercisable - October 31, 2022	1,992,539	$	7.52	3.5	$	349,716

Restricted Stock Units

The 2016 Plan provides for the issuance of RSUs to 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 nine months ended October 31, 2022:


	Shares	Weighted-Average Grant Date Fair Value per RSU
Unvested - January 31, 2022	3,226,759	$	258.85
RSUs granted	1,790,022	316.47
RSUs vested	(1,139,763)	214.84
RSUs forfeited and canceled	(296,995)	291.22
Unvested - October 31, 2022	3,580,023	$	298.99

Executive Performance Share Awards

During three months ended April 30, 2022, the Company created a long-term performance-based equity award program and granted performance share units (“PSUs”) to the Company’s CEO and certain other executives. The vesting of PSUs is conditioned upon the achievement of certain targets for the year ended January 31, 2023. Upon achievement of those conditions, the PSUs vest annually over a period of three years from the date of grant, subject to the executive’s continued employment with the Company. Each vested PSU entitles the executive to one share of common stock. A PSU performance factor of 100 will result in the targeted number of PSUs being vested. The minimum percentage of PSUs that can vest is zero, with a maximum percentage of 200. On the date of grant, the Company assumed a performance factor of 100, which would result in 74,823 PSUs to be issued, if fully vested.

The grant date fair value of these PSUs was $23.7 million at a performance factor of 100, which was determined by using the closing price of the Company’s stock at the date of grant. Compensation expense is being recognized over the requisite service period based on the probability of the performance conditions being satisfied using the accelerated attribution method.

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 2022, the Company issued 72,966 shares of its common stock under the 2017 ESPP. The Company’s current offering period began June 16, 2022 and ends on December 15, 2022.

Stock-Based Compensation Expense

Total stock-based compensation expense recognized in the Company’s unaudited condensed consolidated statements of operations is as follows (in thousands):

Net Loss Per Share

9 Months Ended

Oct. 31, 2022

Earnings Per Share [Abstract]

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.

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 October 31,				Nine Months Ended October 31,
	2022		2021		2022		2021
Numerator:
Net loss	$	(84,841)	$	(81,293)	$	(281,000)	$	(222,418)

Denominator:
Weighted-average shares used to compute net loss per share, basic and diluted	68,916,813		66,386,379		68,325,990		63,750,884

Net loss per share, basic and diluted	$	(1.23)	$	(1.22)	$	(4.11)	$	(3.49)

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 October 31, 2022.

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 October 31,		Nine Months Ended October 31,
	2022	2021	2022	2021
Stock options pursuant to the 2016 Equity Incentive Plan	549,089	722,070	584,933	818,589
Stock options pursuant to the 2008 Stock Incentive Plan	1,537,192	2,250,736	1,680,349	2,476,270

Income Taxes	9 Months Ended
Income Taxes	Oct. 31, 2022
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded a provision for income taxes of $5.0 million and $9.2 million for the three and nine months ended October 31, 2022, respectively, and a provision for income taxes of $2.2 million and $2.4 million for the three and nine months ended October 31, 2021, respectively. The provisions recorded during the three and nine months ended October 31, 2022 and 2021 were driven by the increase in global income and the associated foreign taxes as the Company continues its global expansion The provision for the nine months ended October 31, 2021, was partially offset by the release of the valuation allowance as a result of goodwill recorded associated with an immaterial business combination, as well as the reversal of the deferred tax liability associated with the convertible senior notes upon the adoption of ASU 2020-06. 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 income (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, 2022, the Company’s net unrecognized tax benefits totaled $22.7 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, such as the U.S. Tax Cuts and Jobs Act of 2017 (“Tax Act”). To date, based on the net operating losses and full valuation allowances against the Company’s two most significant tax jurisdictions, the United States and Ireland, the impact of global enacted and proposed legislation has not had an impact on the tax provisions of the financial statements. The Company continues to monitor to ensure both the Company’s financial results and its related tax disclosures are in compliance with any tax legislation.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Summary of Significant Accounting Policies (Policies)	9 Months Ended
Summary of Significant Accounting Policies (Policies)	Oct. 31, 2022
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, 2022 (the “2022 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 period. 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 COVID-19 pandemic and global macroeconomic conditions, including 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, while also disrupting sales channels and marketing activities for an unknown period of time. 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.
