Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of Business	ORGANIZATION AND DESCRIPTION OF BUSINESS Business SentinelOne, Inc. (SentinelOne, we, our, or us) was incorporated in January 2013 in the State of Delaware. On March 29, 2021, we amended our certificate of incorporation to change our name from Sentinel Labs, Inc. to SentinelOne, Inc. We are a cybersecurity provider that delivers an artificial intelligence-powered platform to enable autonomous cybersecurity defense. Our headquarters is located in Mountain View, California with various other global office locations. Initial Public Offering and Private Placement In July 2021, we completed our initial public offering (IPO) and a concurrent private placement, in which we issued and sold an aggregate of 41,678,568 shares of our Class A common stock at $35 per share, including 5,250,000 shares issued upon the exercise of the underwriters’ option to purchase additional shares and 1,428,568 shares issued pursuant to the private placement. We received net proceeds of approximately $1.4 billion after deducting underwriting discounts and commissions.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The condensed consolidated financial statements 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. Accordingly, they do not include all disclosures normally required in annual consolidated financial statements prepared in accordance with GAAP. Therefore, these condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in our final prospectus dated June 29, 2021 and filed with the SEC pursuant to Rule 424(b)(4) on June 30, 2021 (Final Prospectus). In management’s opinion, these condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of our financial position as of July 31, 2021 and the results of operations for the three and six months ended July 31, 2021. 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 full year or any other future interim or annual period. The condensed consolidated financial statements include the accounts of SentinelOne and our wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Fiscal Year Our fiscal year ends on January 31. References to fiscal 2022 and fiscal 2021 refer to the fiscal years ending January 31, 2022 and January 31, 2021, respectively. Forward Stock Split On February 6, 2020, we effected a one-to-three forward stock split of our issued and outstanding shares of common stock and redeemable convertible preferred stock. The par values of common stock and redeemable convertible preferred stock were not adjusted as a result of the stock split. All references to shares of common stock, options, warrants, and redeemable convertible preferred stock and per share amounts have been retroactively adjusted to reflect the forward stock split for the periods presented . Use of Estimates The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. These estimates include, but are not limited to, the valuation of our common stock prior to our IPO in June 2021, stock-based compensation, the period of benefit for deferred contract acquisition costs, standalone selling prices (SSP) for each performance obligation, useful lives of long-lived assets, the incremental borrowing rate (IBR) used for operating lease liabilities, and accounting for income taxes. Actual results could differ from those estimates. As the impact of the COVID-19 pandemic continues to evolve, estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require increased judgment. These estimates and assumptions may change in future periods and will be recognized in the condensed consolidated financial statements as new events occur and additional information becomes known. To the extent our actual results differ materially from those estimates and assumptions, our future financial statements could be affected. Segment and Geographic Information We have a single operating and reportable segment. Our chief operating decision maker (CODM) is our Chief Executive Officer. The CODM reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and assessing financial performance. For information regarding our revenue and long-lived assets by geography, see Notes 3 and 13, respectively. Cash, Cash Equivalents, and Restricted Cash We consider all highly liquid investments purchased with an original maturity of three months or less at the time of purchase to be cash equivalents. Cash equivalents consist of amounts invested in money market funds. Restricted cash consists of collateralized letters of credit established in connection with lease agreements for our office facilities. Restricted cash, current is included within p repaid expenses and other current assets on our consolidated balance sheets. The following table provides a reconciliation of cash, cash equivalents, and restricted cash to the total of these amounts shown in the consolidated statements of cash flows (in thousands): As of July 31, As of January 31 2021 2021 Cash and cash equivalents $ 1,684,702 $ 395,472 Restricted cash, current 1,379 946 Restricted cash, non-current 2,722 2,694 $ 1,688,803 $ 399,112 Concentrations of Credit Risk Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, short-term investments, and accounts receivable. We maintain our cash, cash equivalents, restricted cash, and short-term investments with high-credit-quality financial institutions mainly in the U.S. and Israel. We have not experienced any credit losses relating to our cash, cash equivalents, restricted cash, and short-term investments. For accounts receivable, we are exposed to credit risk in the event of nonpayment by customers to the extent of the amounts recorded on the consolidated balance sheets. We perform periodic credit evaluations of our customers and generally do not require collateral. The only channel partner that represented 10% or more of accounts receivable, net for the periods presented was as follows: As of July 31, As of January 31 2021 2021 Channel partner A 18 % 23 % There were no end customers that represented 10% or more of accounts receivable as of July 31, 2021 or January 31, 2021. Channel partners that represented 10% or more of our total revenue for the periods presented were as follows: Three Months Ended July 31, Six Months Ended July 31, 2021 2020 2021 2020 Channel partner A 19 % 19 % 18 % 19 % Channel partner B * 13 % * 13 % There were no end customers that represented 10% or more of total revenue for the three and six months ended July 31, 2021 and 2020. Accounts Receivable Accounts receivable are recorded at invoiced amounts and are non-interest bearing. We have a well-established collection history from our channel partners and end customers. We periodically evaluate the collectability of our accounts receivable and provide an allowance for doubtful accounts as necessary, based on the age of the receivable, expected payment ability, and collection experience. As of July 31, 2021 and January 31, 2021, the allowance for doubtful accounts was not material. Recently Adopted Accounting Pronouncement s In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which provides new authoritative guidance with respect to the measurement of credit losses on financial instruments. This update changes the impairment model for most financial assets and certain other instruments by introducing a current expected credit loss (CECL) model. The CECL model is a more forward-looking approach based on expected losses rather than incurred losses, requiring entities to estimate and record losses expected over the remaining contractual life of an asset. We adopted this guidance on February 1, 2021, which did not have a material impact on our condensed consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . This ASU simplifies the measurement of goodwill by eliminating step two of the two-step impairment test. Step two measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. This ASU requires an entity to compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. Additionally, an entity should consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. We adopted this guidance on February 1, 2021, which did not have a material impact on our condensed consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes . This guidance simplifies the accounting for income taxes by eliminating certain exceptions to the In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (ASU 2020-06), which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts in an entity’s own equity. Among other changes, ASU 2020-06 removes the liability and equity separation model for convertible instruments with a cash conversion feature, and as a result, after adoption, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost and convertible preferred stock will be accounted for as a single equity instrument measured at its historical cost, as long as no other features require bifurcation and recognition as derivatives. Additionally, ASU 2020-06 requires the application of the if-converted method for all convertible instruments in the diluted earnings per share calculation and the inclusion of the effect of share settlement for instruments that may be settled in cash or shares, except for certain liability-classified share-based payment awards. The guidance is effective for us on February 1, 2024. We are currently evaluating the impact of this guidance on our condensed consolidated financial statements.

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS We measure fair value based on a three-level hierarchy, maximizing the use of observable inputs, where available, and minimizing the use of unobservable inputs, as follows: Level 1: Assets and liabilities whose values are based on observable inputs such as quoted (unadjusted) prices in active markets for identical assets or liabilities. Level 2: Assets and liabilities whose values are based on inputs from quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the asset or liability. Level 3: Assets and liabilities whose values are based on unobservable inputs that are supported by little or no market activity and that are significant to the overall fair value measurement. The following table summarizes the respective fair value and the classification by level within the fair value hierarchy (in thousands): As of July 31, 2021 Level 1 Level 2 Level 3 Total Assets Cash equivalents: Money market funds $ 40,520 $ — $ — $ 40,520 Short-term investments: Certificates of deposit — 370 — 370 Total assets measured and recorded at fair value $ 40,520 $ 370 $ — $ 40,890 As of January 31, 2021 Level 1 Level 2 Level 3 Total Assets Cash equivalents: Money market funds $ 40,518 $ — $ — $ 40,518 Short-term investments: Certificates of deposit — 364 — 364 Total assets measured and recorded at fair value $ 40,518 $ 364 $ — $ 40,882 There were no transfers between the levels of the fair value hierarchy during the three and six months ended July 31, 2021 and 2020. As of July 31, 2021 and January 31, 2021, the aggregate fair value of our cash equivalents and short-term investments approximated amortized cost and, as such, there were no unrealized gains or losses, either individually or in the aggregate. As of July 31, 2021 and January 31, 2021, our cash and cash equivalents had contractual maturities of three and six months or less and short-term investments had contractual maturities within one year of each respective date.

Debt Disclosure [Abstract]
Long-Term Debt	LONG-TERM DEBTIn May 2018, we entered into a loan and security agreement with a certain lender, which was restated in May 2020, or the Amended Loan and Security Agreement. The Amended Loan and Security Agreement provided a revolving line of credit of up to $45.0 million, maturing in May 2023. In June 2021, we repaid all outstanding indebtedness owed pursuant to the Amended Loan and Security Agreement, terminated the agreement, and closed our revolving line of credit. We had drawn down $20.0 million on the revolving line of credit in May 2020 and repaid the outstanding amounts borrowed under the loan and security agreement in full. All borrowings under the Amended Loan and Security Agreement were secured by substantially all of our assets, including the assets of our wholly-owned subsidiary Scalyr, Inc. (Scalyr). In addition, the terms of the Amended Loan and Security Agreement included certain affirmative covenants that, among other things, required us to maintain certain annual revenue targets during a given covenant period and limited our and our subsidiaries’ abilities to, among other things, dispose of assets, undergo a change in control, merge or consolidate, make acquisitions, incur debt, incur liens, pay dividends, and make investments, in each case subject to certain exceptions. Pursuant to our termination of the Amended Loan and Security Agreement, the related security interests have been removed and the covenants shall be of no further force and effect. In connection with the initial term loan, we issued warrants to purchase shares of common stock with an exercise price of $0.62 per share. The remaining warrants to purchase 954,884 shares of common stock were outstanding and exercisable as of January 31, 2021. During the three months ended July 31, 2021, we issued 940,953 shares of Class B common stock in connection with the cashless exercise of all outstanding warrants to purchase common stock. We incurred interest expense associated with our long-term debt of $0.5 million during both the three months ended July 31, 2021 and 2020, and $0.8 million for both the six months ended July 31, 2021 and 2020 .

Stock-Based Compensation	STOCK-BASED COMPENSATION 2021 Equity Incentive Plan In May 2021, our board of directors and in June 2021, our stockholders approved our 2021 Equity Incentive Plan (2021 Plan) as a successor to our 2013 Equity Incentive Plan (2013 Plan) and 2011 Stock Incentive Plan (2011 Plan) with the purpose of granting stock-based awards to employees, directors, officers and consultants, including stock options, restricted stock awards and restricted stock units (RSUs). A total of 35,281,596 shares of Class A common stock were initially available for issuance under the 2021 Plan. Our compensation committee administers the 2021 Plan. The number of share of our Class A common stock available for issuance under the 2021 Plan is subject to an annual increase on the first day of each fiscal year beginning on February 1, 2022, equal to the lesser of: (i) five percent (5%) of the aggregate number of outstanding shares of all classes of our common stock as of the last day of the immediately preceding fiscal year or (ii) such other amount as our board of directors may determine. The 2013 Plan and 2011 Plan (together, the Prior Plans) were terminated in July 2021, in connection with the adoption of our 2021 Plan, and stock-based awards are no longer granted under the Prior Plans. However, the Prior Plans will continue to govern the terms and conditions of the outstanding awards previously granted thereunder. Any shares underlying stock options that are expired, canceled, forfeited or repurchased under the Prior Plans will be automatically transferred to the 2021 Plan and be available for issuance as Class A common stock. 2013 Equity Incentive Plan Our 2013 Plan was adopted by our board of directors in June 2013 and approved by our stockholders in July 2013. The 2013 Plan provides for the grant of stock-based awards to employees, officers, directors, and other service providers. As of July 31, 2021, we had 47,976,585 shares reserved for issuance pursuant to grants under our 2013 Plan. Options granted under the 2013 Plan expire ten years from the date of grant. The options generally vest 25% on the first anniversary of the grant date and monthly over the course of the following three years. A summary of our stock option plan activity under the 2013 Plan is as follows: Number of Options Weighted-Average Exercise Price Weighted-Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in thousands) Outstanding as of January 31, 2021 37,231,191 $ 1.68 8.34 $ 442,515 Granted 14,048,623 $ 9.66 Exercised (3,296,747) $ 1.24 Forfeited (352,965) $ 3.86 Outstanding as of July 31, 2021 47,630,102 $ 4.04 8.44 $ 2,156,010 Expected to vest as of July 31, 2021 47,630,206 $ 4.04 8.44 $ 2,156,010 Vested and exercisable as of July 31, 2021 15,494,656 $ 1.51 7.28 $ 740,631 The weighted-average grant-date fair value of options granted during the three months ended July 31, 2021 and 2020 was $18.16 per share and $1.87 per share, respectively. The weighted-average grant-date fair value of options granted during the six months ended July 31, 2021 and 2020 was $13.14 per share and $1.28 per share, respectively. The aggregate grant-date fair value of options vested during the three months ended July 31, 2021 and 2020 was $8.1 million and $1.1 million, respectively. The aggregate grant-date fair value of options vested during the six months ended July 31, 2021 and 2020 was $12.3 million and $2.0 million, respectively. The aggregate intrinsic value is the difference between the exercise price and the estimated fair value of the underlying common stock. The aggregate intrinsic value of options exercised during the three months ended July 31, 2021 and 2020 was $53.8 million and $0.7 million, respectively. The aggregate intrinsic value of options exercised during the six months ended July 31, 2021 and 2020 was $80.9 million and $1.9 million, respectively. As of July 31, 2021, we had unrecognized stock-based compensation expense related to unvested options of $174.5 million that is expected to be recognized on a straight-line basis over a weighted-average period of 2.1 years. Restricted Stock Units A summary of our RSUs is as follows: Number of Shares Weighted-Average Grant Date Fair Value Outstanding as of January 31, 2021 — $ — Granted 346,483 $ 32.39 Forfeited — — Outstanding as of July 31, 2021 346,483 $ 32.39 As of July 31, 2021, we had unrecognized stock-based compensation expense related to unvested RSUs of $10.3 million that is expected to be recognized on a straight-line basis over a weighted-average period of 2.1 years. Performance Milestone Options In February 2021, we granted 1,243,636 performance milestone options to purchase shares of common stock under the 2013 Plan. The performance milestone options are subject to service-based vesting conditions and achievements of certain milestones. We recognize compensation cost on a graded basis over the total requisite service period for each separately vesting portion of the performance tranches related to these performance milestone options. The grant-date fair value of the performance milestone options was $10.25, $10.37, and $10.49 per share for each of the performance tranches using the Black-Scholes option-pricing model. We assess the probability that the performance condition will be met for each of the performance tranches at the end of each reporting period, and recognize cumulative expense only for the performance tranches that are assessed to be probable of vesting. During the three and six months ended July 31, 2021, we recorded $5.6 million and $8.7 million of stock-based compensation expense, respectively. As of July 31, 2021, we had unrecognized stock-based compensation expense related to unvested performance milestone options of $4.2 million, that is expected to be recognized over the remaining vesting period of 0.4 years. Milestone Options In March 2021, we granted 1,404,605 options to purchase shares of common stock subject to service-based, performance-based, and market-based vesting conditions to our Chief Executive Officer and Chief Financial Officer under the 2013 Plan. These stock options will vest 100% upon the occurrence of our IPO (the performance-based vesting condition) and the achievement of certain milestone events and our share price targets (the market-based vesting conditions), subject to the executive’s continued service to us from the grant date through the milestone events. For these options, we used a Monte Carlo simulation to determine the fair value at the grant date and the implied service period. During both the three and six months ended July 31, 2021, we recorded $1.2 million of stock-based compensation expense. As of July 31, 2021, we had unrecognized stock-based compensation expense related to unvested milestone options of $18.1 million, that is expected to be recognized over the remaining vesting period of 5.1 years. Restricted Common Stock In connection with the Scalyr acquisition, we granted 1,315,099 shares of restricted common stock with a fair value of $14.59 per share at the time of grant, that vest over a period of two years. During the three and six months ended July 31, 2021, we recorded $3.1 million and $5.5 million of stock-based compensation expense, respectively. As of July 31, 2021, we had unrecognized stock-based compensation expense related to this unvested restricted common stock of $14.1 million that is expected to be recognized over the remaining vesting period of 1.1 years. 2011 Stock Incentive Plan As part of the Scalyr acquisition, we assumed 2,138,347 options to purchase shares of common stock under the 2011 Plan, at a weighted-average exercise price of $1.74 per share and weighted-average fair value of $13.10 per share, of which 755,368 options remained outstanding with a weighted-average exercise price of $1.72 per share as of July 31, 2021. As of July 31, 2021, 96,579 options were vested and exercisable with a weighted-average exercise price of $1.72 per share. The aggregate grant-date fair value of options vested during the three and six months ended July 31, 2021 was $4.7 million and $8.7 million, respectively. The total unrecognized stock-based compensation expense related to these options was $6.7 million, that is expected to be recognized on a straight-line basis over a weighted-average period of 1.1 years. During the three and six months ended July 31, 2021, 266,980 and 1,328,595 options, respectively, were exercised with an aggregate intrinsic value of $7.0 million and $22.7 million, respectively. Secondary Stock Sales In May 2021, we facilitated a secondary sale of our common stock. Under the terms of the sale, certain Preferred Stock investors purchased 85,403 shares of common stock from an employee at $23.00 per share for an aggregate purchase price of $2.0 million. We did not recognize any stock-based compensation expense during the three months ended July 31, 2021 in connection with this sale. In June 2021, we facilitated certain secondary sales of our common stock. Under the terms of the sales, certain Preferred Stock investors purchased 305,724 shares of common stock from certain employees at prices ranging from $21.00 to $52.00 per share for an aggregate purchase price of $8.7 million. The stock-based compensation expense recognized in connection with these sales were not material. Common Stock Subject to Repurchase Common stock purchased by employees pursuant to an early exercise of stock options are not deemed, for accounting purposes, to be outstanding until those shares vest according to their respective vesting schedules and accordingly, the consideration received for early exercises are initially recorded as a liability and reclassified to common stock and additional paid-in capital as the underlying awards vest. These unvested shares may be repurchased by us in case of employment termination at the price paid by the purchaser for such shares. As of July 31, 2021, the balance of common stock subject to repurchase was not material. Stock-Based Compensation Expense We estimate the fair value of stock options granted using the Black-Scholes option pricing model based on the following assumptions: Expected term – We determine expected term based on the average period the options are expected to remain outstanding using the simplified method, calculated as the midpoint of the options’ vesting term and contractual expiration period, until sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior becomes available. Expected volatility – Since there is little trading history of our common stock, expected volatility is estimated based on the historical volatilities of a group of comparable publicly traded companies. Risk-free interest rate – The risk-free interest rate is based on U.S. Treasury yields for a period that corresponds with the expected term of the award. Dividend yield – As we do not currently issue dividends and do not expect to issue dividends on our common stock in the foreseeable future, the expected dividend yield is zero. Fair value of underlying common stock – Prior to the completion of our IPO, the fair value of our common stock was determined by the board of directors by considering a number of objective and subjective factors including input from management and contemporaneous third-party valuations. After the completion of our IPO, the fair value of our common stock is determined by the closing price, on the date of grant, of our Class A common stock, which is traded on the New York Stock Exchange.

The ESPP initially reserved and authorized the issuance of up to a total of 7,056,319 shares of common stock to eligible employees. The number of shares reserved for issuance and sale under the ESPP will automatically increase on the first day of each fiscal year, starting on February 1, 2022 for the first ten The Company recognized stock-based compensation expense related to ESPP of $1.0 million during both the three and six months ended July 31, 2021. As of July 31, 2021, $2.6 million amount has been withheld on behalf of employees for a future purchase under the ESPP due to the timing of payroll deductions. There were no purchases for the three or six months ended July 31, 2021 related to the ESPP.

Earnings Per Share [Abstract]
Net Loss Per Share Attributable to Common Stockholders	NET LOSS PER SHARE ATTRIBUTABLE TO COMMON STOCKHOLDERS Basic and diluted net loss per share attributable to common stockholders is computed in conformity with the two-class method required for participating securities. Basic net loss per share is computed by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potentially dilutive common stock equivalents to the extent they are dilutive. For purposes of this calculation, redeemable convertible preferred stock, stock options, restricted stock awards, RSUs, ESPP, early exercised stock options, and common stock warrants are considered to be common stock equivalents but have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is anti-dilutive for all periods presented. The rights, including the liquidation and dividend rights, of the holders of Class A and Class B common stock are identical, except with respect to voting, converting, and transfer rights. As the liquidation and dividend rights are identical, the undistributed earnings are allocated on a proportionate basis to each class of common stock and the resulting basic and diluted net loss per share attributable to common stockholders are, therefore, the same for both Class A and Class B common stock on both individual and combined basis. Basic and diluted net loss per share attributable to common stockholders was as follows (in thousands, except share and per share data): Three Months Ended July 31, Six Months Ended July 31, 2021 2020 2021 2020 Numerator: Net loss attributable to Class A and Class B common stockholders $ (68,163) $ (22,938) $ (130,797) $ (49,576) Denominator: Weighted-average shares used in computing net loss per share attributable to Class A and Class B common stockholders, basic and diluted 120,520,061 34,480,356 82,394,440 34,229,843 Net loss per share attributable to Class A and Class B common stockholders, basic and diluted $ (0.57) $ (0.67) $ (1.59) $ (1.45) The following potentially dilutive securities were excluded from the computation of diluted net loss per share attributable to common stockholders because their inclusion would have been anti-dilutive: As of July 31, As of July 31, 2021 2020 Redeemable convertible preferred stock — 145,837,255 Stock options 48,385,470 37,718,141 Common stock warrants — 1,276,686 Shares subject to repurchase 63,492 82,500 RSUs 346,483 — ESPP 85,827 — Restricted common stock 1,315,099 — Contingently issuable shares 1,317,079 — Total 51,513,450 184,958,625

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Legal Contingencies From time to time, we may be a party to various legal proceedings and subject to claims in the ordinary course of business. BlackBerry Litigation Starting in October 2019, BlackBerry Corp. and its subsidiary Cylance, Inc. (BlackBerry) filed a total of nine proceedings (seven lawsuits and two arbitrations) against us and certain former BlackBerry employees who joined our company. In these proceedings, BlackBerry alleges that it has viable legal claims as a result of its former employees joining us. Many of these proceedings have now been dismissed. The status of each of the currently pending proceedings is discussed below. We have defended against these claims and expect to continue to defend against these claims. BlackBerry Corp., et al. v. Coulter, et al. On October 17, 2019, BlackBerry commenced an action captioned BlackBerry Corp., et al. v. Coulter, et al. , No. 953-10-19 (Vt. Super. Ct.) (Vermont Action) against Chris Coulter, an employee on our Vigilance services team. On October 23, 2019, BlackBerry filed an amended complaint that added us as a defendant. The amended complaint asserts claims against us for conspiracy, tortious interference with contract, aiding and abetting breach of fiduciary duties, and misappropriation of trade secrets. The court entered a preliminary injunction order enjoining Mr. Coulter from working for us through February 2021. As a result of the court’s order, Mr. Coulter chose to seek other employment and is no longer employed by us. On January 15, 2021, the court entered an order narrowing the scope of the case and limiting the claims against us in order to avoid conflict with a similar action that was previously filed in California and was dismissed. The Vermont Action is currently pending. On October 25, 2019, BlackBerry commenced an action captioned BlackBerry Corp., et al v. Coulter, et al., No. 2019-0854-JTL (Del. Ch.) against Mr. Coulter and us in Delaware Chancery Court. The court stayed this case pending resolution of the Vermont Action, and on February 7, 2020, BlackBerry voluntarily dismissed without prejudice all claims against Mr. Coulter and us. On December 3, 2019, BlackBerry initiated a largely duplicative action in arbitration solely against Mr. Coulter administered by JAMS, an alternative dispute resolution provider. That arbitration action, however, was dismissed on or about March 30, 2021, with JAMS informing us that they had closed their files on this matter on April 30, 2021. BlackBerry Corp., et al. v. Page, et al. On November 18, 2019, BlackBerry commenced an action captioned BlackBerry Corp., et al. v. Page, et al. , No. 2019-CP-07-2552 (S.C. Cir. Ct.) against Barnaby Page, a go-to-market employee, and us, in a South Carolina state court. The complaint asserts claims against us for aiding and abetting breach of fiduciary duties, tortious interference with contract, and misappropriation of trade secrets. Following initial discovery, on August 27, 2020, we and Mr. Page filed a joint motion for judgment on the pleadings. The motion is currently pending and discovery is ongoing. Blackberry Corp. et al. v. Sentinel Labs, Inc., et al. On January 16, 2020, BlackBerry commenced the action captioned, BlackBerry Corp., et al. v. Sentinel Labs, Inc. , et al., No. 20CV361950 (Cal. Super. Ct. Santa Clara Cnty.) (Current California Action), against us and unnamed “Doe” defendants, asserting claims against us for trade secret misappropriation and unfair business practices. We filed counterclaims that, in part, seek to invalidate any agreements allegedly supporting BlackBerry’s claims against its former employees. On December 14, 2020, we filed a motion requesting that BlackBerry sufficiently identify any trade secrets it alleges we misappropriated in accordance with California law. On February 12, 2021, the court granted that motion in part, including striking BlackBerry’s expert testimony, and limiting the scope of discovery to customer lists and sales-related information. On March 15, 2021, BlackBerry re-filed a statement identifying its trade secrets to pursue broader claims and discovery. In response, on April 5, 2021, we again filed a motion requesting that BlackBerry sufficiently identify any trade secrets under California law. On June 2, 2021, the court granted the motion in our favor, absent a few discrete areas permitted by the court. On July 2, 2021, Blackberry filed its third amended trade secret identification. In response, on July 16, 2021, we submitted a motion challenging these claims. In its third trade secret statement, in response to our motion again challenging the sufficiency of its trade secret disclosures, Blackberry voluntarily dropped various claims. The parties are currently in the early stages of discovery over the revised trade secret disclosures approved by the court on August 31, 2021. We continue to litigate this action, including actively pursing our counterclaims against them. BlackBerry Corp., et al. v. Quinn, et al. On February 17, 2020, BlackBerry commenced the action captioned BlackBerry Corp., et al. v. Quinn, et al., No. D-1-GN-20-00096 (Tex. Civ. Ct. – Travis Cnty.) against Sean Quinn, a go-to-market employee, and us, in Texas state court. On August 8, 2020, we and Mr. Quinn moved to stay or dismiss the case in light of the overlapping issues between this case and the Current California Action. On September 21, 2020, the court stayed this case pending resolution of the Current California Action. This lawsuit remains stayed and is pending in abeyance before the Texas court. We have not recorded any accruals for loss contingencies associated with these legal proceedings, determined that an unfavorable outcome is probable, or determined that the amount or range of any possible loss is reasonably estimable. We believe that there are no other pending or threatened legal proceedings that are likely to have a material adverse effect on our condensed consolidated financial statements. Warranties and Indemnification Our services are generally warranted to deliver and operate in a manner consistent with general industry standards that are reasonably applicable and materially conform with our documentation under normal use and circumstances. Our contracts generally include certain provisions for indemnifying customers against liabilities if our products or services infringe a third party’s intellectual property rights. We also offer a limited warranty to certain customers, subject to certain conditions, to cover certain costs incurred by the customer in case of a cybersecurity breach on us. We have entered into an insurance policy to cover our potential liability arising from this limited warranty arrangement. We have not incurred any material costs related to such obligations and have not accrued any liabilities related to such obligations in the condensed consolidated financial statements as of July 31, 2021 and January 31, 2021. In addition, we also indemnify certain of our directors and executive officers against certain liabilities that may arise while they are serving in good faith in their company capacities. We maintain director and officer insurance coverage that would generally enable us to recover a portion of any future amounts paid.

Retirement Benefits [Abstract]
Employee Benefit Plan	EMPLOYEE BENEFIT PLAN Our U.S. employees participate in a 401(k) defined contribution plan sponsored by us. Contributions to the plan are discretionary. There were no matching contributions by us for the three and six months ended July 31, 2021 and 2020, respectively. Israeli Severance Pay Israeli labor law generally requires payment of severance pay upon dismissal of an employee or upon termination of employment in certain other circumstances. Pursuant to Section 14 of the Severance Compensation The se payments release us from any future severance payment obligation with respect to these employees; as such, any liability for severance pay due to these employees and the deposits under Section 14 are not recorded as an asset on our consolidated balance sheets. We recorded severance expenses related to these employees of $1.0 million and $0.6 million for the three months ended July 31, 2021 and 2020 , respectively, and $1.8 million and $1.1 million for the six months ended July 31, 2021 and 2020

Acquisitions

Business Combination and Asset Acquisition [Abstract]
Acquisitions	ACQUISITIONS On February 6, 2021, we executed a merger agreement to acquire 100% of the issued and outstanding equity securities (the Acquisition) of Scalyr, a leading cloud-native, cloud-scale data analytics platform. This acquisition will allow us to advance our data ingestion, search, and retention capabilities. The Acquisition closed on February 9, 2021 and has been accounted for as a business combination in accordance with ASC Topic 805, Business Combinations . The aggregate consideration transferred was $125.3 million, of which $5.0 million was paid in cash, $106.2 million was comprised of 7,277,214 shares of common stock, and $14.1 million was comprised of assumed options to purchase 2,138,347 shares of common stock. As part of the merger agreement, we entered into non-compete agreements with the founder and the co-founder of Scalyr with a term of three years and a fair value of $0.7 million. The fair value of the non-compete agreements was excluded from the purchase consideration and the net assets acquired, resulting in purchase consideration of $124.6 million. The amounts recognized will be finalized as the information necessary to complete the analysis is obtained, but no later than one year after the acquisition date. The assets acquired and liabilities assumed in connection with the acquisition were recorded at their preliminary fair value on the date of acquisition as follows (in thousands): Amount Cash and cash equivalents $ 699 Accounts receivable 3,665 Restricted cash 444 Prepaid expense 277 Intangible assets 17,150 Goodwill 108,193 Accounts payable (412) Deferred revenue (5,041) Other liabilities (347) Total purchase consideration $ 124,628 The excess of the purchase price over the preliminary fair value of net tangible and intangible assets acquired has been assigned to goodwill. Goodwill represents the future benefits as a result of the acquisition that will enhance our product available to both new and existing customers and increase our competitive position. Goodwill is not deductible for tax purposes. The following table sets forth the preliminary amounts allocated to the intangible assets identified and their estimated useful lives as of the date of acquisition: Fair Value Useful Life (in thousands) (in years) Developed technology $ 15,500 7 Customer relationships 1,500 2 Trademarks 150 2 Total intangible assets acquired $ 17,150 The preliminary fair value assigned to the developed technology was determined using the multi-period excess earnings method of the income approach. The preliminary fair value assigned to the customer relationships was determined using the distributor method under the income approach, which includes estimates of customer attrition rates. The intangible assets acquired are expected to be amortized over their useful lives on a straight-line basis. As part of the consideration transferred, we withheld 1,317,079 shares of our common stock with a fair value of $14.59 per share at the time of grant (Holdback Shares) and $0.4 million of cash related to certain obligations, including indemnification for potential breach of general representations and warranties of the sellers. The Holdback Shares and cash are expected to be released 18 months from the Acquisition closing date, subject to claims for any obligations. In connection with the Acquisition, we granted 1,315,099 shares of restricted common stock that vest over a period of two years contingent on continued employment, for which stock-based compensation expense will be recognized ratably over the vesting period. There was no other contingent consideration or cash consideration expected to be paid out subsequent to the Acquisition. The results of operations of Scalyr have been included in our condensed consolidated financial statements from the date of Acquisition. We have incurred zero and $1.0 million of transaction costs in connection with the Acquisition during the three and six months ended July 31, 2021, respectively.These costs were recorded as general and administrative expenses in the condensed consolidated statements of operations. The followin g unaudited pro forma financial information summarizes the results of operations of SentinelOne and Scalyr as if the Acquisition occurred on February 1, 2020 (in thousands): Three Months Ended July 31, Six Months Ended July 31, 2021 2020 2021 2020 Revenue $ 45,749 $ 22,920 $ 83,219 $ 42,555 Net loss $ (60,952) $ (32,761) $ (125,944) $ (74,314) Our consolidated statements of operations from the acquisition date to the period ended July 31, 2021 includes revenue and net loss of Scalyr of $5.0 million and $0.9 million, respective ly. The pro forma results reflect certain adjustments for the amortization of acquired intangible assets, adjustments to revenue resulting from the fair value adjustment to deferred revenue, recognition of stock-based compensation, and acquisition-related costs. Such pro forma amounts are not necessarily indicative of the results that actually would have occurred had the Acquisition been completed on the date indicated, nor is it indicative of our future operating results.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The condensed consolidated financial statements 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. Accordingly, they do not include all disclosures normally required in annual consolidated financial statements prepared in accordance with GAAP. Therefore, these condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in our final prospectus dated June 29, 2021 and filed with the SEC pursuant to Rule 424(b)(4) on June 30, 2021 (Final Prospectus). In management’s opinion, these condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of our financial position as of July 31, 2021 and the results of operations for the three and six months ended July 31, 2021. 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 full year or any other future interim or annual period. The condensed consolidated financial statements include the accounts of SentinelOne and our wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Fiscal Year	Fiscal Year Our fiscal year ends on January 31. References to fiscal 2022 and fiscal 2021 refer to the fiscal years ending January 31, 2022 and January 31, 2021, respectively.
Forward Stock Split	Forward Stock Split On February 6, 2020, we effected a one-to-three forward stock split of our issued and outstanding shares of common stock and redeemable convertible preferred stock. The par values of common stock and redeemable convertible preferred stock were not adjusted as a result of the stock split. All references to shares of common stock,
Use of Estimates	Use of Estimates The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. These estimates include, but are not limited to, the valuation of our common stock prior to our IPO in June 2021, stock-based compensation, the period of benefit for deferred contract acquisition costs, standalone selling prices (SSP) for each performance obligation, useful lives of long-lived assets, the incremental borrowing rate (IBR) used for operating lease liabilities, and accounting for income taxes. Actual results could differ from those estimates. As the impact of the COVID-19 pandemic continues to evolve, estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require increased judgment. These estimates and assumptions may change in future periods and will be recognized in the condensed consolidated financial statements as new events occur and additional information becomes known. To the extent our actual results differ materially from those estimates and assumptions, our future financial statements could be affected.
Segment and Geographic Information	Segment and Geographic InformationWe have a single operating and reportable segment. Our chief operating decision maker (CODM) is our Chief Executive Officer. The CODM reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and assessing financial performance.
Cash, Cash Equivalents, and Restricted Cash	Cash, Cash Equivalents, and Restricted Cash We consider all highly liquid investments purchased with an original maturity of three months or less at the time of purchase to be cash equivalents. Cash equivalents consist of amounts invested in money market funds. Restricted cash consists of collateralized letters of credit established in connection with lease agreements for our office facilities. Restricted cash, current is included within p repaid expenses and other current assets on our consolidated balance sheets.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, short-term investments, and accounts receivable. We maintain our cash, cash equivalents, restricted cash, and short-term investments with high-credit-quality financial institutions mainly in the U.S. and Israel.
Accounts Receivable	Accounts ReceivableAccounts receivable are recorded at invoiced amounts and are non-interest bearing. We have a well-established collection history from our channel partners and end customers. We periodically evaluate the collectability of our accounts receivable and provide an allowance for doubtful accounts as necessary, based on the age of the receivable, expected payment ability, and collection experience.
Recently Adopted Accounting Pronouncements and Recent Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncement s In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which provides new authoritative guidance with respect to the measurement of credit losses on financial instruments. This update changes the impairment model for most financial assets and certain other instruments by introducing a current expected credit loss (CECL) model. The CECL model is a more forward-looking approach based on expected losses rather than incurred losses, requiring entities to estimate and record losses expected over the remaining contractual life of an asset. We adopted this guidance on February 1, 2021, which did not have a material impact on our condensed consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . This ASU simplifies the measurement of goodwill by eliminating step two of the two-step impairment test. Step two measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. This ASU requires an entity to compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. Additionally, an entity should consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. We adopted this guidance on February 1, 2021, which did not have a material impact on our condensed consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes . This guidance simplifies the accounting for income taxes by eliminating certain exceptions to the In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (ASU 2020-06), which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts in an entity’s own equity. Among other changes, ASU 2020-06 removes the liability and equity separation model for convertible instruments with a cash conversion feature, and as a result, after adoption, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost and convertible preferred stock will be accounted for as a single equity instrument measured at its historical cost, as long as no other features require bifurcation and recognition as derivatives. Additionally, ASU 2020-06 requires the application of the if-converted method for all convertible instruments in the diluted earnings per share calculation and the inclusion of the effect of share settlement for instruments that may be settled in cash or shares, except for certain liability-classified share-based payment awards. The guidance is effective for us on February 1, 2024. We are currently evaluating the impact of this guidance on our condensed consolidated financial statements.
