Summary of Significant Accounting Policies (Policies) | 3 Months Ended

Apr. 30, 2017
Accounting Policies [Abstract] |
Basis of Presentation | The accompanying unaudited condensed consolidated financial statements, which include the accounts of the Company and its wholly owned subsidiaries, have been prepared in conformity with U.S. generally accepted accounting principles (GAAP) and applicable rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. All intercompany balances and transactions have been eliminated in consolidation. The consolidated balance sheet as of January 31, 2017 included herein was derived from the audited financial statements as of that date. The unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the balance sheet, statements of operations, statements of comprehensive loss and the 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 ending January 31, 2018 or any future period. The Company’s fiscal year ends on January 31. References to fiscal 2018, for example, refer to the fiscal year ending January 31, 2018.
Principles of Consolidation | The condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s final prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended, on April 7, 2017 (the Prospectus).
Use of Estimates | The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. The Company bases its estimates on historical experience and on other assumptions that its management believes are reasonable under the circumstances. Actual results could vary from those estimates. The Company’s most significant estimates and judgments involve revenue recognition with respect to the determination of the relative selling prices for the Company’s services, determination of the fair value of the Company’s common stock prior to the completion of the IPO, valuation of the Company’s stock-based awards, valuation of deferred income tax assets and contingencies.
Share-Based Compensation | All stock-based compensation to employees, including the purchase rights issued under the Company's 2017 Employee Stock Purchase Plan (ESPP), is based on the fair value of the awards on the date of grant. This cost is recognized as an expense following the straight-line attribution method, over the requisite service period, for stock options, restricted stock units (RSUs) and restricted stock, and over the offering period, for the purchase rights issued under the ESPP. The Company uses the Black-Scholes option pricing model to measure the fair value of its stock options and the purchase rights issued under the ESPP. The fair value of the RSUs is determined using the fair value of the Company’s Class A common stock on the date of grant. Prior to adoption of ASU 2016-09, the stock-based compensation was recorded net of estimated forfeitures. In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-09, “Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” This new guidance was intended to simplify several areas of accounting for stock-based compensation arrangements, including the accounting for income taxes, the classification of excess tax benefits on the statement of cash flows and the accounting for forfeitures. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. The Company adopted this guidance in the three months ended April 30, 2017. The new guidance allows entities to account for forfeitures as they occur. The Company elected to account for forfeitures as they occur and adopted this provision on a modified retrospective basis. An adjustment of $0.2 million representing cumulative prior years’ impact was recognized as an adjustment to decrease retained earnings in the period of adoption. The adoption of the amendments related to the accounting for income taxes and classification of excess tax benefits on the statement of cash flows are adopted prospectively. See Note 11 for further details of the effects of adoption of the new accounting standard on income taxes. Adoption of all other changes in the new guidance did not have a significant impact on the Company's consolidated financial statements. The Company accounts for equity awards issued to employees and non-employees based on the fair value of the award, determined using the Black-Scholes option valuation model. The unvested options issued to non-employees are remeas ured to fair value at the end of each reporting period. Prior to the IPO, the fair value of the Company’s common stock was determined by the estimated fair value of the Company’s common stock at the time of grant. After the IPO, the Company uses the market closing price of its Class A common stock on the date of grant for the fair value.
Net Loss per Share | The Company computes basic and diluted net loss per share attributable to common stockholders in conformity with the two-class method required for participating securities. Under the two-class method, basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, less shares subject to repurchase, without consideration for potentially dilutive securities as they do not share in losses. The diluted net loss per share attributable to common stockholders is computed giving effect to all potential dilutive common stock equivalents outstanding for the period. For purposes of this calculation, options to purchase common stock, unvested RSUs, employee stock purchase plan, shares subject to repurchase from early exercised options, and common stock and restricted stock issued in connection with certain business combinations are considered common stock equivalents but have been excluded from the calculation of diluted net loss per share attributable to common stockholders as the effect is antidilutive. Since the Company's IPO, Class A and Class B common stock are the only outstanding equity of the Company. The rights of the holders of Class A and Class B common stock are identical, except with respect to voting and conversion. Each share of Class A common stock is entitled to one vote per share and each share of Class B common stock is entitled to 10 votes per share. Shares of Class B common stock may be converted into Class A common stock at any time at the option of the stockholder on a one-for-one basis, and are automatically converted into Class A common stock upon sale or transfer, subject to certain limited exceptions. Shares of Class A common stock are not convertible.
New Accounting Pronouncements | In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (ASU 2014-09) and has modified the standard thereafter. The standard replaces existing revenue recognition rules with a comprehensive revenue measurement and recognition standard and expanded disclosure requirements. ASU 2014-09, as amended, becomes effective for the Company on February 1, 2018. The standard permits the use of either the retrospective or modified retrospective transition method. Under the retrospective transition method, the standard applies to contracts in all reporting periods presented. Under the modified retrospective transition method, the standard applies only to contracts still open as of February 1, 2018, recognizing in beginning retained earnings an adjustment for the cumulative effect of the change and providing additional disclosures comparing results to previous rules. The Company is currently evaluating the retrospective transition method. Upon initial evaluation, the Company believes the key changes in the standard that may impact its accounting for revenue recognition include contract modifications. In addition, the requirement to defer incremental contract acquisition costs and recognize them over the contract period or expected customer life will affect the Company’s accounting for sales commissions and the determination of related customer life for amortization purposes. The Company has assigned internal resources, engaged a third-party service provider and has a preliminary project plan to evaluate the impacts of implementation, including systems implementations. The Company will continue to evaluate and analyze all other aspects of Topic 606 that may impact it. In January 2016, the FASB issued ASU No. 2016-01 (Subtopic 825-10), Financial Instruments Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01), which primarily affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. In addition, the FASB clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The accounting for other financial instruments, such as loans, investments in debt securities and financial liabilities is largely unchanged. ASU 2016-01 is effective for fiscal years, beginning after December 15, 2018 and interim periods in fiscal years beginning after December 15, 2019. Early adoption is permitted. The Company is currently evaluating the impact of the adoption on its condensed consolidated financial statements, if any. In February 2016, the FASB issued ASU No. 2016-02 (Topic 842), Leases (ASU 2016-02), which supersedes the guidance in topic ASC 840, Leases. The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. ASU 2016-02 is effective for fiscal years beginning after December 15, 2019 and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of this standard on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment (ASU 2017-04), which removes the second step of the goodwill impairment test that requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. This guidance is effective for interim and annual reporting periods beginning after December 15, 2019 and will be applied prospectively. Management does not expect the adoption of this guidance to have any impact on the Company’s financial position, results of operations or cash flows. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805) Clarifying the Definition of a Business (ASU 2017-04), which amends the guidance of FASB Accounting Standards Codification Topic 805, “Business Combinations,” adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation. This guidance is effective for annual and interim periods beginning after December 15, 2017, and early adoption is permitted under certain circumstances. The Company has not early adopted this guidance and is currently evaluating the impact of the adoption of this standard on its condensed consolidated financial statements.
