Basis of Presentation and Summary of Significant Accounting Policies	3 Months Ended
	Apr. 30, 2021
Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Principles of Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America (“GAAP”) and include the accounts of the Company’s wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated on consolidation. The unaudited condensed consolidated balance sheet as of January 31, 2021 included herein was derived from the audited financial statements as of that date, but does not include all disclosures, including certain notes required by GAAP on an annual reporting basis. In management's opinion, the unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to state fairly the balance sheet, statements of comprehensive loss, statements of redeemable convertible preferred stock and stockholders' deficit, and statements of cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year or any future period. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K filed with the SEC on March 30, 2021. Direct Listing On September 30, 2020, the Company completed a direct listing of its Class A common stock (the “Direct Listing”) on the NYSE. The Company incurred fees related to financial advisory service, audit, and legal expenses in connection with the Direct Listing and recorded general and administrative expenses of $1.2 million for the three months ended April 30, 2020. The Company recorded no general and administrative expenses in connection with the Direct Listing for the three months ended April 30, 2021. Prior to the Direct Listing, all 73.6 million outstanding shares of redeemable convertible preferred stock were converted into an equivalent number of shares of Class B common stock. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the consolidated financial statements and accompanying notes. Estimates and assumptions reflected in the consolidated financial statements include, but are not limited to, revenue recognition, the useful lives and carrying values of long-lived assets, the fair value of the Convertible Notes (as defined in Note 4), the fair value of common stock for periods prior to the Direct Listing, stock-based compensation expense, the period of benefit for deferred contract acquisition costs, and income taxes. Actual results could differ from those estimates. Risks and Uncertainties As a result of the COVID-19 pandemic, the Company has temporarily closed its headquarters and other physical offices, required its employees and contractors to work remotely, and implemented travel restrictions, all of which represent a significant disruption in how the Company operates its business. The operations of its partners and customers have likewise been disrupted. 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 extent and effectiveness of containment and mitigation actions and the availability and widespread use of effective vaccines, 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. In particular, the conditions caused by this pandemic could affect the rate of global IT spending and could adversely affect demand for the Company’s platform, lengthen the Company’s sales cycles, reduce the value or duration of subscriptions, negatively impact collections of accounts receivable, reduce expected spending from new customers, cause some of the Company’s paying customers to go out of business, limit the ability of the Company’s direct sales force to travel to customers and potential customers, and affect contraction or attrition rates of the Company’s customers, all of which could adversely affect the Company’s business, results of operations, and financial condition. As of the date of issuance of the financial statements, the Company is not aware of any specific event or circumstance related to COVID-19 that would require it to update its estimates or judgments or adjust the carrying value of its assets or liabilities. Actual results could differ from those estimates and any such differences may be material to the condensed consolidated financial statements. Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents, and marketable securities. Substantially all the Company’s cash and cash equivalents are held by four financial institutions that management believes are of high credit quality. Such deposits may, at times, exceed federally insured limits. Cash equivalents are invested in highly rated money market funds. A large portion of the Company’s customers authorize the Company to bill their credit card accounts through the Company’s third-party payment processing partners, presenting additional credit risk. For the three months ended April 30, 2021 and April 30, 2020, there was no individual customer that accounted for 10% or more of the Company’s revenues. The Company had one customer account for approximately 29% and 13% of accounts receivable as of April 30, 2021 and January 31, 2021, respectively. Fair Value of Financial Instruments The carrying amounts reflected in the condensed consolidated balance sheets for cash equivalents, accounts receivable, and accounts payable approximate their respective fair values due to the short maturities of those instruments. Available-for-sale marketable securities are recorded at fair value on the condensed consolidated balance sheets. The Company accounts for certain of its financial assets at fair value. In determining and disclosing fair value, the Company uses a fair value hierarchy established by U.S. GAAP. The guidance defines fair value as an exit price, representing the amount that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the Company utilizes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1—Observable inputs such as quoted prices in active markets. Level 2—Inputs other than the quoted prices in active markets that are observable either directly or indirectly. Level 3—Unobservable inputs in which there is little or no market data and that are significant to the fair value of the assets or liabilities. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considers counterparty credit risk in its assessment of fair value. Recently Issued Accounting Pronouncements Not Yet Adopted In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity's Own Equity, which simplifies the accounting for certain convertible instruments, amends the guidance on derivative scope exceptions for contracts in an entity's own equity, and modifies the guidance on diluted earnings per share calculations as a result of these changes. The guidance is effective for the Company’s fiscal years beginning after February 1, 2022, and earlier adoption is permitted. The Company is currently evaluating the impact of adopting ASU 2020-06. Recently Adopted Accounting Pronouncements On February 1, 2021, the Company adopted ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires the measurement and recognition of expected credit losses for financial assets held at amortized costs, including accounts receivables. It also eliminates the concept of other-than-temporary impairment and requires credit losses related to available-for-sale debt securities to be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. These changes will result in more timely recognition of credit losses. The adoption of the guidance did not have a material impact on the Company’s condensed consolidated financial statements. On February 1, 2021, the Company adopted ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40), Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The amendments in ASU No. 2018-15 amend the definition of a hosting arrangement and requires a customer in a hosting arrangement that is a service contract to capitalize certain costs as if the arrangement were an internal-use software project. The Company adopted ASU No. 2018-15 as of February 1, 2021 using a prospective transition approach.

The Company periodically evaluates its investments for other-than-temporary declines in fair value. The unrealized losses on the available-for-sale securities were primarily due to unfavorable changes in interest rates subsequent to the initial purchase of these securities. Gross unrealized losses of the Company’s available-for-sale securities that have been in a continuous unrealized loss position for twelve months or longer were immaterial as of April 30, 2021 and January 31, 2021. The Company expects to recover the full carrying value of its available-for-sale securities in an unrealized loss position as it does not intend or anticipate a need to sell these securities prior to recovering the associated unrealized losses. The Company also expects any credit losses would be immaterial based on the high-grade credit rating for each of such available-for-sale securities. As a result, the Company does not consider any portion of the unrealized losses as of April 30, 2021 or January 31, 2021 to represent an other-than temporary impairment or credit losses.

In April 2020, the Company entered into a five-year $40.0 million term loan agreement with Silicon Valley Bank. As of April 30, 2021, $40.0 million was drawn and $39.8 million was outstanding under this term loan. The fair value of the term loan approximates its carrying value since the interest rate is at market.

In January 2020 and June 2020, the Company issued convertible notes to a trust affiliated with the Company’s CEO. The fair value of the convertible notes at issuance on January 30, 2020 and June 26, 2020 was $203.0 million

and $112.0 million, respectively. There were no significant changes in fair value between January 30, 2020 and January 31, 2020. At April 30, 2021, the fair values of the convertible notes issued in January 2020 and in June 2020 were $375.9 million and $190.9 million, respectively. The Company considers the fair values of the convertible notes to be a Level 3 measurement as the fair value is estimated using significant unobservable inputs. The fair value of the convertible notes was measured using a binomial lattice model. Inputs used to determine the estimated fair value of the convertible notes include the equity volatility of comparable companies, the risk-free interest rate, and the estimated fair value of the Company’s common stock.

As part of the agreement, the Company was required to issue a $17.0 million letter of credit upon access to the office space, which occurred in the year ended January 31, 2021. The Company participated in the construction of the office space and has incurred construction costs to prepare the office space for its use, which will be partially reimbursed by the landlord. During the year ended January 31, 2021, all three phases of this lease commenced, and as a result, the Company recognized total ROU assets of $175.5 million, with corresponding operating lease liabilities of $173.4 million, on the consolidated balance sheet as of the respective commencement dates of these three phases. The Company expects to incur a total of approximately $392.4 million of future minimum payments and capital commitments, net of tenant improvement receivables, as of April 30, 2021, inclusive of $372.1 million of net lease payments included in the future minimum lease payments table above and the remaining capital commitments related to the build-out of the Company’s new corporate headquarters referenced in Note 8. Commitments and Contingencies. The lease arrangement also includes a fee for access to additional shared space, for which future payments total $3.9 million.

Common Stock

There are two classes of common stock that total 1,500,000,000 authorized shares: 1,000,000,000 authorized shares of Class A common stock and 500,000,000 authorized shares of Class B common stock. There are 91,685,723 shares of Class A common stock and 71,785,101 shares of Class B common stock issued and outstanding as of April 30, 2021.

Stock Plans

The Company has a 2009 Stock Plan (the “2009 Plan”), a 2012 Amended and Restated Stock Plan (the “2012 Plan”), and a 2020 Equity Incentive Plan (the “2020 Plan”). Each plan was initially established to grant equity awards to employees and consultants of the Company to assist in attracting, retaining, and motivating employees and consultants and to provide incentives to promote the success of the Company’s business.

Options granted under each of the plans may be either incentive stock options (“ISOs”) or nonqualified stock options (“NSOs”). ISOs may be granted only to Company employees (including officers and directors who are also employees). NSOs may be granted to Company employees and consultants. Restricted stock units may also be granted under the 2012 Plan and the 2020 Plan. Options under the 2012 and 2020 Plans may be granted for periods of up to 10 years. The exercise price of ISOs and NSOs shall not be less than 100% of the estimated fair value of the shares on the date of grant as determined by the Company’s board of directors (the “Board of Directors”). Options

granted generally vest over four years and vest at a rate of 25% upon the first anniversary of the vesting commencement date and 1/48 per month thereafter.

The Company has also issued RSUs pursuant to the 2012 Plan and 2020 Plan. RSUs granted generally vest on a predefined rate over a period of four years contingent upon continuous service.

Shares of common stock purchased under the 2012 Plan and the 2020 Plan plans are subject to certain restrictions and repurchase rights, including the right of first refusal by the Company for sale or transfer of shares to outside parties.

Early Exercise of Employee Options

The 2009 Plan and 2012 Plan allow for the early exercise of stock options. The consideration received for an early exercise of an option is considered to be a deposit of the exercise price, and the related dollar amount is recorded as a liability and reflected in accrued expenses and other current liabilities and other liabilities in the condensed consolidated balance sheets. This liability is reclassified to additional paid-in capital as the awards vest. If a stock option is early exercised, the unvested shares may be repurchased by the Company in case of employment termination at the price paid by the purchaser for such shares. Shares that were subject to repurchase totaled 548,299 and 1,148,628 at April 30, 2021 and 2020, respectively.

Determination of Fair Values

The assumptions used in the Black-Scholes pricing model for stock-based compensation for options granted in the periods below were as follows:

2020 Employee Stock Purchase Plan

In September 2020, the Board of Directors adopted and approved the 2020 Employee Stock Purchase Plan (“ESPP”), which became effective on the effective date of the Company's registration statement on Form S-1 filed with the SEC in connection with the Direct Listing. The ESPP initially reserved and authorized the issuance of up to a total of 2,000,000 shares of Class A common stock to participating employees.

The initial offering period began September 30, 2020 and will end on September 15, 2022, with purchase dates of March 15, 2021, September 15, 2021, March 15, 2022, and September 15, 2022. The ESPP provides for 24-month offering periods beginning September 16 and March 16 of each year, with each offering period consisting of four six-month purchase periods, except for the initial offering period which began on September 30, 2020 and will end on September 15, 2022. The purchase price of shares of Class A common stock under an offering will be the lesser of: (i) 85% of the fair market value of such shares of Class A common stock on the offering date, and (ii) 85% of the fair market value of such shares of Class A common stock on the applicable purchase date.

Current employees who purchase shares under the ESPP may not sell such shares prior to the first anniversary of such purchase date and such shares will be designated with an applicable resale restriction. As of April 30, 2021, 250,270 shares have been purchased under the ESPP.

During the three months ended April 30, 2021, the Company recognized $2.4 million of stock-based compensation expense related to ESPP and withheld $2.0 million in contributions from employees. As of April 30, 2021, total unrecognized compensation costs related to the 2020 ESPP was $6.6 million, which will be amortized over a weighted average vesting term of 1.0 year.

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Apr. 30, 2021
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America (“GAAP”) and include the accounts of the Company’s wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated on consolidation.
Basis of Accounting	The unaudited condensed consolidated balance sheet as of January 31, 2021 included herein was derived from the audited financial statements as of that date, but does not include all disclosures, including certain notes required by GAAP on an annual reporting basis. In management's opinion, the unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to state fairly the balance sheet, statements of comprehensive loss, statements of redeemable convertible preferred stock and stockholders' deficit, and statements of cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year or any future period. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K filed with the SEC on March 30, 2021.
Direct Listing	Direct Listing On September 30, 2020, the Company completed a direct listing of its Class A common stock (the “Direct Listing”) on the NYSE. The Company incurred fees related to financial advisory service, audit, and legal expenses in connection with the Direct Listing and recorded general and administrative expenses of $1.2 million for the three months ended April 30, 2020. The Company recorded no general and administrative expenses in connection with the Direct Listing for the three months ended April 30, 2021. Prior to the Direct Listing, all 73.6 million outstanding shares of redeemable convertible preferred stock were converted into an equivalent number of shares of Class B common stock.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the consolidated financial statements and accompanying notes. Estimates and assumptions reflected in the consolidated financial statements include, but are not limited to, revenue recognition, the useful lives and carrying values of long-lived assets, the fair value of the Convertible Notes (as defined in Note 4), the fair value of common stock for periods prior to the Direct Listing, stock-based compensation expense, the period of benefit for deferred contract acquisition costs, and income taxes. Actual results could differ from those estimates.
Risks and Uncertainties	Risks and Uncertainties As a result of the COVID-19 pandemic, the Company has temporarily closed its headquarters and other physical offices, required its employees and contractors to work remotely, and implemented travel restrictions, all of which represent a significant disruption in how the Company operates its business. The operations of its partners and customers have likewise been disrupted. 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 extent and effectiveness of containment and mitigation actions and the availability and widespread use of effective vaccines, 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. In particular, the conditions caused by this pandemic could affect the rate of global IT spending and could adversely affect demand for the Company’s platform, lengthen the Company’s sales cycles, reduce the value or duration of subscriptions, negatively impact collections of accounts receivable, reduce expected spending from new customers, cause some of the Company’s paying customers to go out of business, limit the ability of the Company’s direct sales force to travel to customers and potential customers, and affect contraction or attrition rates of the Company’s customers, all of which could adversely affect the Company’s business, results of operations, and financial condition. As of the date of issuance of the financial statements, the Company is not aware of any specific event or circumstance related to COVID-19 that would require it to update its estimates or judgments or adjust the carrying value of its assets or liabilities. Actual results could differ from those estimates and any such differences may be material to the condensed consolidated financial statements.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents, and marketable securities. Substantially all the Company’s cash and cash equivalents are held by four financial institutions that management believes are of high credit quality. Such deposits may, at times, exceed federally insured limits. Cash equivalents are invested in highly rated money market funds. A large portion of the Company’s customers authorize the Company to bill their credit card accounts through the Company’s third-party payment processing partners, presenting additional credit risk. For the three months ended April 30, 2021 and April 30, 2020, there was no individual customer that accounted for 10% or more of the Company’s revenues. The Company had one customer account for approximately 29% and 13% of accounts receivable as of April 30, 2021 and January 31, 2021, respectively.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying amounts reflected in the condensed consolidated balance sheets for cash equivalents, accounts receivable, and accounts payable approximate their respective fair values due to the short maturities of those instruments. Available-for-sale marketable securities are recorded at fair value on the condensed consolidated balance sheets. The Company accounts for certain of its financial assets at fair value. In determining and disclosing fair value, the Company uses a fair value hierarchy established by U.S. GAAP. The guidance defines fair value as an exit price, representing the amount that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the Company utilizes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1—Observable inputs such as quoted prices in active markets. Level 2—Inputs other than the quoted prices in active markets that are observable either directly or indirectly. Level 3—Unobservable inputs in which there is little or no market data and that are significant to the fair value of the assets or liabilities. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considers counterparty credit risk in its assessment of fair value.
Recently Issued Accounting Pronouncements Not Yet Adopted and Recently Adopted Accounting Pronouncements	Recently Issued Accounting Pronouncements Not Yet Adopted In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity's Own Equity, which simplifies the accounting for certain convertible instruments, amends the guidance on derivative scope exceptions for contracts in an entity's own equity, and modifies the guidance on diluted earnings per share calculations as a result of these changes. The guidance is effective for the Company’s fiscal years beginning after February 1, 2022, and earlier adoption is permitted. The Company is currently evaluating the impact of adopting ASU 2020-06. Recently Adopted Accounting Pronouncements On February 1, 2021, the Company adopted ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires the measurement and recognition of expected credit losses for financial assets held at amortized costs, including accounts receivables. It also eliminates the concept of other-than-temporary impairment and requires credit losses related to available-for-sale debt securities to be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. These changes will result in more timely recognition of credit losses. The adoption of the guidance did not have a material impact on the Company’s condensed consolidated financial statements. On February 1, 2021, the Company adopted ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40), Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The amendments in ASU No. 2018-15 amend the definition of a hosting arrangement and requires a customer in a hosting arrangement that is a service contract to capitalize certain costs as if the arrangement were an internal-use software project. The Company adopted ASU No. 2018-15 as of February 1, 2021 using a prospective transition approach.
