Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Basis of Presentation	Description of Business and Basis of Presentation Organization and Nature of Operations Sumo Logic, Inc. (the “Company”) was incorporated in Delaware in March 2010. The Company provides, on a cloud-native software-as-a-service (“SaaS”) delivery model, a software platform that enables organizations of all sizes to address the challenges and opportunities presented by digital transformation, modern applications, and cloud computing. The platform enables organizations to automate the collection, ingestion, and analysis of application, infrastructure, security, and IoT data to derive actionable insights. Basis of Presentation and Principles of Consolidation The Company’s condensed consolidated financial statements and accompanying notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission, (“SEC”), regarding interim financial reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP have been condensed or omitted, and accordingly the balance sheet as of January 31, 2021, and related disclosures, have been derived from the audited consolidated financial statements at that date but do not include all of the information required by GAAP for complete consolidated financial statements. The accompanying interim unaudited condensed consolidated financial statements and related financial information should be read in conjunction with the audited consolidated financial statements and the related notes contained in the Company’s Annual Report on Form 10-K for the year ended January 31, 2021, as filed with the SEC on March 12, 2021. The Company’s condensed consolidated financial statements and accompanying notes include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. These unaudited condensed consolidated financial statements have been prepared on the same basis as the Company’s annual consolidated financial statements and, in the opinion of management, reflect all normal recurring adjustments that are necessary for the fair statement of the Company’s condensed consolidated financial information. The results of operations for the three and six months ended July 31, 2021 are not necessarily indicative of the results to be expected for the year ending January 31, 2022 or for any other interim period or for any other future year. Fiscal Year The Company’s fiscal year ends on January 31. Unless otherwise stated, references to year in these condensed consolidated financial statements relate to the above described fiscal year rather than calendar year.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Use of Estimates and Judgments The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, as of the date of the financial statements, and the reported amounts of income and expenses during the reporting period. These estimates are based on information available as of the date of the financial statements and may involve subjective or significant judgment by the Company; therefore, actual results could differ from the Company’s estimates. The Company’s accounting policies that involve judgment include revenue recognition, period of benefit for deferred sales commissions, assumptions used for estimating the fair value of common stock to calculate stock-based compensation (prior to the closing of the Company’s initial public offering (“IPO”)), capitalization of internal-use software costs, valuation of goodwill and intangible assets, estimate of credit losses for accounts receivable and marketable securities, and valuation allowances associated with income taxes. COVID-19 While the duration and extent of the COVID-19 pandemic depends on future developments that cannot be accurately predicted at this time, such as the duration and spread of the outbreak, the emergence of variants of the virus, the extent and effectiveness of containment actions, and the effectiveness of vaccination efforts, it has already had an adverse effect on the global economy and the ultimate societal and economic impact of the COVID-19 pandemic remains unknown. The Company may experience customer losses, including due to bankruptcy or customers ceasing operations, which may result in delays in collections or an inability to collect accounts receivable from these customers. The extent to which the COVID-19 pandemic, including the emergence of the Delta variant, may continue to impact the Company’s financial condition, results of operations, or liquidity continues to remain uncertain, and as of the date of issuance of these financial statements, the Company is not aware of any specific event or circumstance that would require an update to its estimates or judgments or an adjustment to the carrying value of the Company’s assets or liabilities. These estimates may change, as new events occur and additional information is obtained, which will be recognized in the condensed 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. In May 2020, as part of the Company’s efforts to respond to the COVID-19 pandemic and ensure longer-term financial stability, the Company initiated cost reduction measures, including a headcount reduction. The headcount reduction resulted in $1.2 million of severance and benefits expense and $0.1 million in stock-based compensation expense for the year ended January 31, 2021. Significant Accounting Policies Other than those described below, there have been no changes to the Company’s significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended January 31, 2021, that have had a material impact on its condensed consolidated financial statements and related notes. Marketable Securities Marketable securities consist of U.S. Treasury securities, corporate debt securities, commercial paper, foreign government obligations, supranational securities, and certificates of deposits. The Company classifies marketable securities as available-for-sale at the time of purchase and reevaluate such classification as of each balance sheet date. Interest receivable on these securities is presented in other current assets on the condensed consolidated balance sheets. All marketable securities are recorded at their estimated fair values. When the fair value of a marketable security declines below its amortized cost basis, the carrying value of the security will be reduced to its fair value if it is more likely than not that management is required to sell the impaired security before recovery of its amortized basis, or management has the intention to sell the security. If neither of these conditions are met, the Company determines whether any portion of the decline is due to credit losses. Any portion of that decline attributable to credit losses, to the extent expected to be nonrecoverable before the sale of the security, is recognized in the Company’s condensed consolidated statement of operations. When the fair value of the security declines below its amortized cost basis due to changes in interest rates, such amounts are recorded in accumulated other comprehensive income (loss) and are recognized in the Company’s condensed consolidated statement of operations only if the Company sells or intends to sell the security before recovery of its cost basis. Realized gains and losses are determined based on the specific identification method and are reported in interest and other income (expense), net in the Company’s condensed consolidated statements of operations. Leases The Company enters into operating lease arrangements for real estate assets related to office space. The Company determines if an arrangement is or contains a lease at commencement by evaluating various factors, including whether a vendor’s right to substitute an identified asset is substantive. Lease classification is determined at the lease commencement date, which is the date the leased assets are made available for use. Operating leases are included in operating lease right-of-use assets, operating lease liabilities, current, and operating lease liabilities, noncurrent in the condensed consolidated balance sheets. The Company did not have any financing leases in any of the periods presented. Operating lease right-of-use assets (“RoU”) and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Lease payments consist of the fixed payments under the arrangement, less any lease incentives, such as tenant improvement allowances. The Company elected the practical expedient which allows the Company to not allocate consideration between lease and non-lease components. Variable costs, such as maintenance and utilities based on actual usage, are not included in the measurement of right-to-use assets and lease liabilities but are expensed when the event determining the amount of variable consideration to be paid occurs. The interest rate implicit in our operating leases is not readily determinable, and therefore an incremental borrowing rate (“IBR”) is estimated to determine the present value of future payments. The estimated IBR factors in a hypothetical interest rate on a collateralized basis with similar terms, payments, and economic environments. Lease expenses are recognized on a straight-line basis over the lease term. The Company generally uses the non-cancelable lease term when recognizing the right-of-use assets and lease liabilities, unless it is reasonably certain that a renewal or termination option will be exercised. The Company accounts for lease components and non-lease components as a single lease component. Leases with a term of 12 months or less are not recognized on the condensed consolidated balance sheets but are recognized as expense on a straight-line basis over the term of the lease. Property and Equipment, Net Property and equipment are stated at cost less accumulated depreciation. Depreciation expense is computed using the straight-line method over the estimated useful lives of the assets. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. Land is not depreciated. Costs of maintenance and repairs that do not improve or extend the lives of the respective assets are expensed as incurred. Upon retirement or sale, the cost and related accumulated depreciation and amortization are removed from the Company’s consolidated balance sheet and the resulting gain or loss is reflected in the Company’s consolidated statement of operations. The following table presents the estimated useful lives of the Company’s property and equipment: Useful Life Computer and hardware equipment 3 years Furniture and fixtures 5 years Leasehold improvements Shorter of lease term or estimated useful life Capitalized internal-use software 3 years Building 10 - 22 years Related Party Transactions Certain members of the Company’s board of directors serve as directors of, or are executive officers of, and in some cases are investors in, companies that are customers or vendors of the Company. The Company received cash payments of $1.5 million from a related party for the year ended January 31, 2021. Related party transactions were not material as of July 31, 2021, or for the six months ended July 31, 2021 or 2020. Recently Adopted Accounting Pronouncements The Company assesses the adoption impacts of recently issued accounting pronouncements by the Financial Accounting Standards Board (“FASB”) on its condensed consolidated financial statements. The sections below describe impacts from newly adopted pronouncements. In February 2016, the FASB issued Accounting Standard Update (“ASU”) No. 2016-02, Leases (Topic 842) . This guidance is intended to increase transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet and disclosing key information about lease arrangements. In June 2020, the FASB issued ASU No. 2020-05, Revenue from Contracts with Customers (Topic 606) and Leases (Topic 842): Effective Dates for Certain Entities, which amended the effective date of the new guidance. The Company adopted this guidance using a modified retrospective approach as of February 1, 2021. The Company has elected to use the optional transition method which allows the Company to apply the guidance of ASC 840, including disclosure requirements, in the comparative periods presented. In addition, the Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed the Company to carry forward the historical lease classification related to agreements entered prior to adoption. The adoption of the new standard resulted in recognition of operating lease RoU assets and operating lease liabilities of $10.3 million and $11.5 million, respectively, as of February 1, 2021. There was no cumulative impact of transition to the Company’s accumulated deficit balance as of the adoption date. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instrument s, and has since issued various amendments including ASU No. 2018-19, ASU No. 2019-04, and ASU No. 2019-05. The guidance and related amendments modify the accounting for credit losses for most financial assets and require the use of an expected loss model, replacing the currently used incurred loss method. Under this model, entities will be required to estimate the lifetime expected credit loss on such instruments and record an allowance to offset the amortized cost basis of the financial asset, resulting in a net presentation of the amount expected to be collected on the financial asset. The Company adopted this guidance as of February 1, 2021, and the adoption of this guidance did not have a material impact on the Company’s condensed consolidated financial statements. Recently Issued Accounting Pronouncements Under the JOBS Act, the Company meets the definition of an emerging growth company and can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the Company is no longer an emerging growth company or until the Company affirmatively and irrevocably opts out of the extended transition period.

Fair Value Measurements

Fair Value Measurements	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company measures its financial assets and liabilities at fair value each reporting period using a fair value hierarchy that prioritizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs may be used to measure fair value, as follows: Level 1 Observable inputs, such as 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 that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company uses the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. The carrying amounts of the Company’s financial instruments, which include cash equivalents, accounts receivable, accounts payable, and accrued expenses approximate fair value because of the short maturity of those instruments. The following tables present the fair value of the Company’s financial assets and liabilities measured at fair value on a recurring basis, based on the three-tier fair value hierarchy (in thousands): As of July 31, 2021 Level 1 Level 2 Level 3 Total Cash equivalents: Money market funds $ 87,132 $ — $ — $ 87,132 Marketable securities: U.S. Treasury securities — 63,262 — 63,262 Corporate debt securities — 122,793 — 122,793 Commercial paper — 33,328 — 33,328 Foreign government obligations — 12,718 — 12,718 Supranational securities — 35,604 — 35,604 Certificates of deposit — 7,401 — 7,401 Total financial assets $ 87,132 $ 275,106 $ — $ 362,238 As of January 31, 2021 Level 1 Level 2 Level 3 Total Cash equivalents: Money market funds $ 397,200 $ — $ — $ 397,200 The Company had $0.4 million and $0.3 million of restricted cash invested in money market funds that is not included in the tables above as of July 31, 2021 and January 31, 2021, respectively. In connection with the Loan and Security agreement, discussed in Note 7, the Company issued 32,276 warrants to purchase shares of the Company’s redeemable convertible preferred stock. The Company used a Black-Scholes option valuation model to value its redeemable convertible preferred stock warrant liability at inception and on subsequent valuation dates. Changes in the fair values of the redeemable convertible preferred stock warrant liability were recorded as interest and other income (expense), net in the Company’s condensed consolidated statements of operations. All 32,276 warrants to purchase shares of redeemable convertible preferred stock converted into warrants to purchase common stock upon the closing of the Company’s IPO and the related liability was reclassified to additional-paid in capital in the Company’s condensed consolidated balance sheet. During the six months ended July 31, 2021, 21,746 warrants were exercised. There were no transfers out of level 3 during the six months ended July 31, 2021 and 2020. The following is a summary of available-for sale marketable securities, excluding those securities classified within cash and cash equivalents on the condensed consolidated balance sheet as of July 31, 2021 (in thousands): As of July 31, 2021 Amortized Cost Unrealized Gain Unrealized Loss Fair Value U.S. Treasury securities $ 63,247 $ 15 $ — $ 63,262 Corporate debt securities 122,795 22 (24) 122,793 Commercial paper 33,329 1 (2) 33,328 Foreign government obligations 12,721 — (3) 12,718 Supranational securities 35,603 2 (1) 35,604 Certificates of deposit 7,400 1 — 7,401 Total marketable securities $ 275,095 $ 41 $ (30) $ 275,106 The Company does not believe that any unrealized losses are attributable to credit-related factors based on its evaluation of available evidence. To determine whether a decline in value is related to credit loss, the Company evaluates, among other factors: the extent to which the fair value is less than the amortized cost basis, changes to the rating of the security by a rating agency and any adverse conditions specifically related to an issuer of a security or its industry. No impairment loss has been recorded on the securities included in the table above, as the Company believes that the decrease in fair value of these securities is temporary. The following table presents the contractual maturities of the Company’s marketable securities (in thousands): July 31, Due in one year or less $ 192,652 Due after one year and within five years 82,454 Total marketable securities $ 275,106 The Company had no marketable securities as of January 31, 2021.

The aggregate amount recorded as purchase consideration was $32.7 million, of which $8.6 million was paid or to be paid in cash, and $24.1 million was comprised of 1,123,697 shares of the Company’s common stock. The value of consideration assigned to such shares of common stock was based on the closing price of the Company’s common stock on the date of acquisition, or $21.49 per share. Additionally, 71,644 shares of common stock were issued with a fair value of $21.49 per share at the time of grant and will be recorded as stock-based compensation. These shares are subject to risk of forfeiture which lapses in full 1.5 years after the acquisition date.

Certain stock options held by Sensu employees were assumed by the Company with a total fair value of $0.6 million and will be recognized as stock-based compensation over the remaining service period. See Note 10 for more details on the Sensu options assumed. The acquisition was accounted for as a business combination and the total purchase consideration was allocated to the net tangible and intangible assets and liabilities based on their fair values on the acquisition date and the excess was recorded as goodwill. The values assigned to the assets acquired and liabilities assumed are based on preliminary estimates of fair value available as of the issuance date of these condensed consolidated financial statements and may be adjusted during the measurement period of up to 12 months from the date of acquisition as further information becomes available. Any changes in the fair values of the assets acquired and liabilities assumed during the measurement period may result in adjustments to goodwill.

Leases [Abstract]
Leases	Leases The Company leases office space globally under non-cancelable operating lease agreements that expire at various dates through fiscal 2026. The leases require monthly lease payments that may be subject to annual increases throughout the lease term. Certain of these leases include (i) renewal options at the election of the Company to renew or extend the lease for an additional 6 years, and/or (ii) options to terminate the lease early, subject to certain termination penalties and fees.

Debt Disclosure [Abstract]
Debt	Debt In February 2021, the Company entered into an Amended and Restated Loan and Security Agreement with Silicon Valley Bank (“SVB Agreement”) which provides for a revolving line of credit facility. The SVB Agreement amends and restates the Loan and Security Agreement dated January 31, 2016. Under the SVB Agreement, the Company can borrow up to $50 million. Interest on any drawdown accrues at the prime rate minus a spread rate ranging from 0.25% to 0.75%, as determined by the Company’s adjusted quick ratio, subject to either a 3.00% or 2.50% floor depending on the adjusted quick ratio. The SVB Agreement is secured by substantially all of the Company’s assets and includes restrictive covenants, in each case subject to certain exceptions, that limit the Company’s ability to, among other things: incur debt, grant liens, make acquisitions, suffer changes in control, make investments, make certain dividends or distributions, repurchase or redeem stock, dispose of or transfer assets, and enter into transactions with affiliates. Pursuant to the SVB Agreement, the Company is required to maintain a minimum adjusted quick ratio of 1.25 to 1.00. The SVB Agreement also contains customary events of default, upon which Silicon Valley Bank may declare all or a portion of the Company’s outstanding obligations payable to be immediately due and payable. As of July 31, 2021 and January 31, 2021, the Company did not have any debt balance outstanding.

Legal accruals are recorded when and if it is determined that a loss related to a certain matter is both probable and reasonably estimable. Attorneys representing a purported class of current and former employees in various sales roles alleged potential claims of employee misclassification and related federal and state law claims, which the Company disputed. In response, the Company mediated the dispute, and in August 2020, the Company entered into a settlement agreement with the purported class counsel to resolve the dispute, which was handled in arbitration and resulted in the Company paying $4.5 million to resolve the class-wide claims during the six months ended July 31, 2021.

Equity [Abstract]
Stockholders' Equity and Equity Incentive Plans	Stockholders’ Equity and Equity Incentive Plans Redeemable Convertible Preferred Stock Upon the closing of the Company’s IPO, all 63,761,950 shares of redeemable convertible preferred stock were automatically converted into shares of common stock on a one-to-one basis, and the carrying value of $340.2 million was reclassified into common stock and additional paid-in-capital. As of July 31, 2021, there were no shares of redeemable convertible preferred stock issued and outstanding. Common Stock The Company’s Amended and Restated Certificate of Incorporation authorized the Company to issue 1,000.0 million shares of common stock at a par value of $0.0001 as of July 31, 2021 and January 31, 2021. As of July 31, 2021 and January 31, 2021, approximately 110.1 million and 102.5 million shares of common stock were issued and outstanding, respectively. Each share of common stock is entitled to one vote. The holders of common stock are also entitled to receive dividends whenever funds are legally available and when and if declared by the board of directors, subject to the prior rights of holders of all classes of stock outstanding. As of July 31, 2021 and January 31, 2021, no dividends had been declared. Stock Plans The Company has two equity incentive plans: the 2010 Stock Plan (the “2010 Plan”) and the 2020 Equity Incentive Plan (the “2020 Plan”). In connection with the Company’s IPO in September 2020, the 2010 Plan was terminated and replaced by the 2020 Plan and all shares that remained available for issuance under the 2010 Plan at that time were reserved for issuance under the 2020 Plan. The number of shares of common stock available for issuance under the 2020 Plan will be increased by any shares of common stock subject to awards outstanding under the 2010 Plan that expire or otherwise terminate without having been exercised or issued in full, are tendered to or withheld by the Company for payment of an exercise price or for satisfying tax withholding obligations, or are forfeited to or repurchased by the Company due to failure to vest . The Company has issued stock options and restricted stock units (“RSUs”) to employees, directors, consultants, and advisors pursuant to both the 2010 Plan and 2020 Plan. Employee stock options are granted with an exercise price no less than the fair value of the underlying common stock on the grant date, in general vest based on continuous service over four years, and expire 10 years from the date of grant. The value of RSUs is measured based on the grant date fair value of the awards and in general vest based on satisfying a service-based condition based on continuous service over four years. As of July 31, 2021, there were 15.3 million shares available for grant under the 2020 Plan. The 2020 Plan provides that the number of shares reserved will automatically increase on the first day of each fiscal year, beginning on February 1, 2021, by an amount equal to the least of (i) 12,500,000 shares, (ii) 5% of the outstanding shares of our common stock on the last day of the immediately preceding fiscal year, or (iii) such other amount as the administrator of the 2020 Plan may determine.

Restricted Stock Units The following table is a summary of RSU activity for the six months ended July 31, 2021: Number of Weighted Average Grant Date Fair Value per Share (in thousands) Balance at January 31, 2021 3,757 $ 15.07 Granted (a)(b) 3,846 $ 21.31 Released (1,197) $ 13.39 Forfeited (378) $ 20.07 Balance at July 31, 2021 6,028 $ 19.07 RSUs expected to vest at July 31, 2021 6,028 $ 19.07 ______________ (a) During the six months ended July 31, 2021, of the 3.8 million RSUs granted, 0.1 million awards were subject to both service-based and performance-based vesting conditions. (b) In connection with the acquisitions, the Company agreed to grant 0.4 million RSUs to employees of the acquired companies. As of July 31, 2021, there was $95.2 million of total unrecognized compensation expense related to unvested employee and director RSUs, of which $2.3 million is for the RSUs subject to certain other performance metrics. Total unrecognized compensation expense related to unvested RSUs is expected to be recognized over a weighted-average period of 3.4 years. Sensu Plans In connection with the acquisition of Sensu, the Company assumed 33,267 options to purchase shares of common stock, granted under the Sensu, Inc. Amended and Restated 2017 Equity Incentive Plan, at a weighted-average exercise price of $4.88 per share and weighted-average fair value of $17.19 per share, of which 33,267 remained outstanding as of July 31, 2021. As of July 31, 2021, 2,625 options were vested and exercisable with a weighted-average exercise price of $4.83, and the total unrecognized compensation expense related to these awards was $0.5 million. During the six months ended July 31, 2021, no options were exercised. Jask Labs Plans In connection with the acquisition of Jask Labs, the Company assumed 265,075 options to purchase shares of common stock, granted under the Jask Labs 2015 Stock Option and Grant Plan and the Jask Labs 2018 Equity Incentive Plan (together, the “Jask Plans”), at a weighted-average exercise price of $9.86 per share and weighted-average fair value of $6.39 per share, of which 117,582 and 140,348 remained outstanding as of July 31, 2021 and January 31, 2021, respectively. As of July 31, 2021, 94,764 options were vested and exercisable with a weighted-average exercise price of $10.54, and the total unrecognized compensation expense related to these awards was $0.1 million. During the six months ended July 31, 2021, 22,038 options were exercised. Employee Stock Purchase Plan In September 2020, the board of directors adopted and the stockholders of the Company approved the 2020 Employee Stock Purchase Plan (“ESPP”), which became effective on September 17, 2020. The ESPP initially reserved and authorized the issuance of up to a total of 2,000,000 shares of common stock to participating employees. The number of shares reserved under the ESPP will automatically increase on the first day of each fiscal year, starting on February 1, 2021, in an amount equal to the least of (i) 2,500,000 shares, (ii) 1% of the outstanding shares of our common stock on the last day of the immediately preceding fiscal year, or (iii) such other amount as the administrator of the ESPP may determine. The ESPP generally provides for 24-month offering periods beginning June 15 and December 15 of each year, with each offering period consisting of four six-month purchase periods. On each purchase date, eligible employees will purchase the shares at a price per share equal to 85% of the lesser of (1) the fair market value of the Company’s common stock as of the beginning of the offering period or (2) the fair market value of the Company’s common stock on the purchase date, as defined in the ESPP. Under the reset provision currently authorized, if the closing stock price on the offering date of a new offering falls below the closing stock price on the offering date of an ongoing offering, the ongoing offering would terminate immediately following the purchase of ESPP shares on the purchase date immediately preceding the new offering and participants in the terminated ongoing offering would automatically be enrolled in the new offering (“ESPP reset”), resulting in a modification charge to be recognized over the new offering period. The Company recognized stock-based compensation expense related to the ESPP of $1.7 million and $2.5 million during the three and six months ended July 31, 2021, respectively. As of July 31, 2021 and January 31, 2021, $1.1 million and $2.5 million has been withheld on behalf of employees for a future purchase under the ESPP due to the timing of payroll deductions, respectively. As of July 31, 2021, there was $8.6 million of unrecognized stock-based compensation expense related to the ESPP that is expected to be recognized over an average vesting period of 1.3 years. During the three and six months ended July 31, 2021, 279,600 shares of common stock were issued under the ESPP at a purchase price of $16.90. Stock-Based Compensation Expense The following table presents total stock-based compensation expense included in the condensed consolidated statements of operations (in thousands): Three Months Ended July 31, Six Months Ended July 31, 2021 2020 2021 2020 Cost of revenue $ 156 $ 39 $ 329 $ 101 Research and development (a) 5,969 1,849 10,516 3,878 Sales and marketing 4,172 1,589 7,644 3,116 General and administrative 3,760 1,179 7,701 2,628 Total stock-based compensation expense $ 14,057 $ 4,656 $ 26,190 $ 9,723 ________________ (a) During the six months ended July 31, 2021, the Company did not capitalize any stock-based compensation related to internal-use software development costs. During the three and six months ended July 31, 2020, the Company capitalized stock-based compensation of $0.1 million and $0.2 million related to internal-use software development costs, respectively. The research and development stock-based compensation amounts are presented net of the capitalized costs. In connection with the acquisition of Jask Labs, the Company granted 130,180 shares of restricted common stock, with a fair value of $12.11683 per share at the time of grant, that vest over a period of two years. The Company recorded $0.2 million in stock-based compensation expense related to the vesting of the restricted common stock during the three months ended July 31, 2021 and 2020 and $0.4 million during the six months ended July 31, 2021 and 2020. As of July 31, 2021, the remaining unrecognized stock-based compensation expense of $0.2 million will be recognized over the remaining vesting period. The RSUs granted under the 2010 Plan were subject to service-based and performance-based vesting conditions, which included a liquidity event condition. In certain cases the RSUs are also subject to certain other performance metrics. The liquidity event performance-based vesting condition was deemed probable of occurring up on the completion of the IPO. On that date the Company recorded cumulative stock-based compensation expense of $10.9 million using the accelerated attribution method. The remaining unrecognized stock-based compensation expense will be recorded over the RSUs remaining requisite service periods. Included within these amounts was $1.4 million for the RSUs subject to both the occurrence of a liquidity event and certain other performance metrics. Common Stock Transfers During the six months ended July 31, 2020, certain of the Company’s existing investors acquired outstanding common stock from former employees of the Company, for a purchase price greater than the fair value of the common stock at the time of the transaction. In connection with these stock transfers, the Company waived its right of first refusal and other transfer restrictions applicable to such shares. As a result, the Company recorded stock-based compensation of $0.3 million for the six months ended July 31, 2020, in general and administrative expenses in the condensed consolidated statements of operations. The amount recorded as stock-based compensation represents the difference between the price paid and the estimated fair value at the date of the transaction.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Accounting for income taxes for interim periods generally requires the provision for income taxes to be determined by applying an estimate of the annual effective tax rate for the full fiscal year to income or loss before income taxes, adjusted for discrete items, if any, for the reporting period. The Company updates its estimate of the annual effective tax rate each quarter and records a cumulative adjustment in such period. The Company recorded an income tax benefit of $0.8 million and $0.5 million for the three and six months ended July 31, 2021, respectively. The Company recorded income tax expense $0.2 million and $0.3 million for the three and six months ended July 31, 2020, respectively. Income tax expense consists primarily of income taxes in foreign jurisdictions in which the Company conducts business. Due to the Company’s history of losses in the United States, a full valuation allowance on substantially all of the Company’s deferred tax assets, including net operating loss carryforwards, research and development tax credits, capitalized research and development, and other book versus tax differences was maintained. The Company recorded a one-time tax benefit of $0.7 million due to a partial release of our valuation allowance in connection with the acquisition of Sensu.

Earnings Per Share [Abstract]
Net Loss Per Share	Net Loss per Share Basic net loss per share attributable to the Company’s common stockholders is computed by dividing the net loss attributable to the Company’s common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is the same as basic net loss per share for all years presented because the effects of potentially dilutive items were anti-dilutive given the Company’s net loss position in each period presented. The following table presents the calculation of basic and diluted net loss per share (in thousands, except per share data): Three Months Ended July 31, Six Months Ended July 31, 2021 2020 2021 2020 Net loss $ (32,049) $ (12,217) $ (58,963) $ (35,782) Weighted-average shares outstanding, basic and diluted 107,884 18,649 105,990 18,522 Net loss per share, basic and diluted $ (0.30) $ (0.66) $ (0.56) $ (1.93) The following potential common shares were excluded from the calculation of diluted net loss per share because their effect would have been anti-dilutive for the periods presented (in thousands): Three Months Ended July 31, Six Months Ended July 31, 2021 2020 2021 2020 Stock options 19,626 26,728 19,626 26,728 RSUs 6,028 2,909 6,028 2,909 ESPP 67 — 67 — Warrants 11 32 11 32 Shares subject to repurchase 323 238 323 238 Assumed options for acquisitions 151 175 151 175 Issuable shares for acquisitions 194 576 194 576 Redeemable convertible preferred stock — 63,762 — 63,762 Total anti-dilutive securities 26,400 94,420 26,400 94,420

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	6 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	The Company’s condensed consolidated financial statements and accompanying notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission, (“SEC”), regarding interim financial reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP have been condensed or omitted, and accordingly the balance sheet as of January 31, 2021, and related disclosures, have been derived from the audited consolidated financial statements at that date but do not include all of the information required by GAAP for complete consolidated financial statements. The accompanying interim unaudited condensed consolidated financial statements and related financial information should be read in conjunction with the audited consolidated financial statements and the related notes contained in the Company’s Annual Report on Form 10-K for the year ended January 31, 2021, as filed with the SEC on March 12, 2021.
Principles of Consolidation	The Company’s condensed consolidated financial statements and accompanying notes include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. These unaudited condensed consolidated financial statements have been prepared on the same basis as the Company’s annual consolidated financial statements and, in the opinion of management, reflect all normal recurring adjustments that are necessary for the fair statement of the Company’s condensed consolidated financial information. The results of operations for the three and six months ended July 31, 2021 are not necessarily indicative of the results to be expected for the year ending January 31, 2022 or for any other interim period or for any other future year.
Fiscal Year	The Company’s fiscal year ends on January 31. Unless otherwise stated, references to year in these condensed consolidated financial statements relate to the above described fiscal year rather than calendar year.
Use of Estimates and Judgments	The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, as of the date of the financial statements, and the reported amounts of income and expenses during the reporting period. These estimates are based on information available as of the date of the financial statements and may involve subjective or significant judgment by the Company; therefore, actual results could differ from the Company’s estimates. The Company’s accounting policies that involve judgment include revenue recognition, period of benefit for deferred sales commissions, assumptions used for estimating the fair value of common stock to calculate stock-based compensation (prior to the closing of the Company’s initial public offering (“IPO”)), capitalization of internal-use software costs, valuation of goodwill and intangible assets, estimate of credit losses for accounts receivable and marketable securities, and valuation allowances associated with income taxes.
Covid-19	While the duration and extent of the COVID-19 pandemic depends on future developments that cannot be accurately predicted at this time, such as the duration and spread of the outbreak, the emergence of variants of the virus, the extent and effectiveness of containment actions, and the effectiveness of vaccination efforts, it has already had an adverse effect on the global economy and the ultimate societal and economic impact of the COVID-19 pandemic remains unknown. The Company may experience customer losses, including due to bankruptcy or customers ceasing operations, which may result in delays in collections or an inability to collect accounts receivable from these customers. The extent to which the COVID-19 pandemic, including the emergence of the Delta variant, may continue to impact the Company’s financial condition, results of operations, or liquidity continues to remain uncertain, and as of the date of issuance of these financial statements, the Company is not aware of any specific event or circumstance that would require an update to its estimates or judgments or an adjustment to the carrying value of the Company’s assets or liabilities. These estimates may change, as new events occur and additional information is obtained, which will be recognized in the condensed 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.
Marketable Securities	Marketable securities consist of U.S. Treasury securities, corporate debt securities, commercial paper, foreign government obligations, supranational securities, and certificates of deposits. The Company classifies marketable securities as available-for-sale at the time of purchase and reevaluate such classification as of each balance sheet date. Interest receivable on these securities is presented in other current assets on the condensed consolidated balance sheets. All marketable securities are recorded at their estimated fair values. When the fair value of a marketable security declines below its amortized cost basis, the carrying value of the security will be reduced to its fair value if it is more likely than not that management is required to sell the impaired security before recovery of its amortized basis, or management has the intention to sell the security. If neither of these conditions are met, the Company determines whether any portion of the decline is due to credit losses. Any portion of that decline attributable to credit losses, to the extent expected to be nonrecoverable before the sale of the security, is recognized in the Company’s condensed consolidated statement of operations. When the fair value of the security declines below its amortized cost basis due to changes in interest rates, such amounts are recorded in accumulated other comprehensive income (loss) and are recognized in the Company’s condensed consolidated statement of operations only if the Company sells or intends to sell the security before recovery of its cost basis. Realized gains and losses are determined based on the specific identification method and are reported in interest and other income (expense), net in the Company’s condensed consolidated statements of operations.
Leases	The Company enters into operating lease arrangements for real estate assets related to office space. The Company determines if an arrangement is or contains a lease at commencement by evaluating various factors, including whether a vendor’s right to substitute an identified asset is substantive. Lease classification is determined at the lease commencement date, which is the date the leased assets are made available for use. Operating leases are included in operating lease right-of-use assets, operating lease liabilities, current, and operating lease liabilities, noncurrent in the condensed consolidated balance sheets. The Company did not have any financing leases in any of the periods presented. Operating lease right-of-use assets (“RoU”) and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Lease payments consist of the fixed payments under the arrangement, less any lease incentives, such as tenant improvement allowances. The Company elected the practical expedient which allows the Company to not allocate consideration between lease and non-lease components. Variable costs, such as maintenance and utilities based on actual usage, are not included in the measurement of right-to-use assets and lease liabilities but are expensed when the event determining the amount of variable consideration to be paid occurs. The interest rate implicit in our operating leases is not readily determinable, and therefore an incremental borrowing rate (“IBR”) is estimated to determine the present value of future payments. The estimated IBR factors in a hypothetical interest rate on a collateralized basis with similar terms, payments, and economic environments. Lease expenses are recognized on a straight-line basis over the lease term. The Company generally uses the non-cancelable lease term when recognizing the right-of-use assets and lease liabilities, unless it is reasonably certain that a renewal or termination option will be exercised. The Company accounts for lease components and non-lease components as a single lease component.
Property and Equipment, Net	Property and equipment are stated at cost less accumulated depreciation. Depreciation expense is computed using the straight-line method over the estimated useful lives of the assets. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. Land is not depreciated. Costs of maintenance and repairs that do not improve or extend the lives of the respective assets are expensed as incurred. Upon retirement or sale, the cost and related accumulated depreciation and amortization are removed from the Company’s consolidated balance sheet and the resulting gain or loss is reflected in the Company’s consolidated statement of operations.
Related Party Transactions	Certain members of the Company’s board of directors serve as directors of, or are executive officers of, and in some cases are investors in, companies that are customers or vendors of the Company.
Recently Adopted and Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements The Company assesses the adoption impacts of recently issued accounting pronouncements by the Financial Accounting Standards Board (“FASB”) on its condensed consolidated financial statements. The sections below describe impacts from newly adopted pronouncements. In February 2016, the FASB issued Accounting Standard Update (“ASU”) No. 2016-02, Leases (Topic 842) . This guidance is intended to increase transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet and disclosing key information about lease arrangements. In June 2020, the FASB issued ASU No. 2020-05, Revenue from Contracts with Customers (Topic 606) and Leases (Topic 842): Effective Dates for Certain Entities, which amended the effective date of the new guidance. The Company adopted this guidance using a modified retrospective approach as of February 1, 2021. The Company has elected to use the optional transition method which allows the Company to apply the guidance of ASC 840, including disclosure requirements, in the comparative periods presented. In addition, the Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed the Company to carry forward the historical lease classification related to agreements entered prior to adoption. The adoption of the new standard resulted in recognition of operating lease RoU assets and operating lease liabilities of $10.3 million and $11.5 million, respectively, as of February 1, 2021. There was no cumulative impact of transition to the Company’s accumulated deficit balance as of the adoption date. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instrument s, and has since issued various amendments including ASU No. 2018-19, ASU No. 2019-04, and ASU No. 2019-05. The guidance and related amendments modify the accounting for credit losses for most financial assets and require the use of an expected loss model, replacing the currently used incurred loss method. Under this model, entities will be required to estimate the lifetime expected credit loss on such instruments and record an allowance to offset the amortized cost basis of the financial asset, resulting in a net presentation of the amount expected to be collected on the financial asset. The Company adopted this guidance as of February 1, 2021, and the adoption of this guidance did not have a material impact on the Company’s condensed consolidated financial statements. Recently Issued Accounting Pronouncements Under the JOBS Act, the Company meets the definition of an emerging growth company and can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the Company is no longer an emerging growth company or until the Company affirmatively and irrevocably opts out of the extended transition period.
Fair Value Measurements	The Company measures its financial assets and liabilities at fair value each reporting period using a fair value hierarchy that prioritizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs may be used to measure fair value, as follows: Level 1 Observable inputs, such as 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 that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company uses the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.
