Organization, Consolidation and Presentation of Financial Statements [Abstract]
Overview and Basis of Presentation	Overview and Basis of Presentation Description of Business Okta, Inc. (the Company) pioneered identity in the cloud. The Okta Identity Cloud enables customers to secure their users and connect them to technology, anywhere, anytime and from any device. The Company was originally incorporated in January 2009 as SaaSure Inc., a California corporation, and, in April 2010, the Company reincorporated in Delaware as Okta, Inc. The Company is headquartered in San Francisco, California. Initial Public Offering In April 2017, the Company completed an initial public offering (IPO), in which the Company issued and sold 12,650,000 shares of its newly authorized Class A common stock, which included 1,650,000 shares sold pursuant to the exercise by the underwriters’ option to purchase additional shares at a public offering price of $17.00 per share. The Company received aggregate proceeds of $200.0 million from the IPO, net of underwriters’ discounts and commissions, before deducting offering costs of approximately $5.6 million . Immediately prior to the completion of the IPO, all shares of common stock then outstanding were reclassified as Class B common stock, and all shares of redeemable convertible preferred stock then outstanding were converted into 59,491,640 shares of common stock on a one-to-one basis and then reclassified into Class B common stock. See Note 9 for additional details. As of April 30, 2017 , 12,782,342 shares of the Company’s Class A common stock and 82,442,536 shares of Class B common stock were outstanding. The Class A common stock outstanding includes the shares issued in the IPO and shares converted from Class B common stock upon exercise of stock options subsequent to the IPO. Basis of Presentation and Principles of Consolidation 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 . 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).

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies 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. Significant Accounting Policies The Company’s significant accounting policies are discussed in “Index to Consolidated Financial Statements-Note 2. Summary of Significant Accounting Policies” in the Prospectus. There have been no significant changes to these policies for the three months ended April 30, 2017 , except as noted below: Stock-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.

Business Combinations [Abstract]
Business Combinations	Business Combinations On February 17, 2017, the Company acquired the rights to hire certain employees and a non-exclusive intellectual property license from Stormpath, Inc. (Stormpath), a privately-held technology company which had built a user management and authentication service for software development teams. The transaction has been accounted for as a business combination and is expected to enhance the Company’s product offerings and service by leveraging the talents of the engineering teams. The total consideration of $3.7 million , consisting of 200,000 shares of common stock valued at $2.2 million issued to Stormpath and replacement awards of $1.5 million issued to the hired employees, was recognized as goodwill. See Note 10 for further details on replacement awards issued in this transaction. Goodwill is not deductible for tax purposes. Pro forma results of operations for the transaction have not been presented as they were not material to the condensed consolidated statements of operations. In addition, the Company issued an incremental 800,000 shares of restricted common stock valued at $8.6 million to Stormpath in connection with the transaction. These shares of restricted common stock will vest ratably on the first and second anniversaries of the transaction date upon achieving the respective performance conditions, including the continued employment of certain employees with Okta and the wind down of Stormpath, Inc. entity. The aggregate fair value, as determined on the date of the transaction, of the shares of restricted common stock will be recognized as post-combination stock-based compensation in the statement of operations over two years based on an accelerated attribution method. See Note 10 for further details.

The Company had one and five short-term investments in unrealized loss positions as of April 30, 2017 and January 31, 2017 , respectively. There were no material gross unrealized gains or losses from available-for-sale securities and no material realized gains or losses from available-for-sale securities that were reclassified out of accumulated other comprehensive income for the three months ended April 30, 2017 or 2016 . For available-for-sale debt securities that have unrealized losses, the Company evaluates whether (i) it has the intention to sell any of these investments and (ii) whether it is not more likely than not that it will be required to sell any of these available-for-sale debt securities before recovery of the entire amortized cost basis. Based on this evaluation, the Company determined that there were no other-than-temporary impairments associated with short-term investments as of April 30, 2017 and January 31, 2017 . The following tables present the contractual maturities of the Company’s short-term investments as of April 30, 2017 and January 31, 2017 (in thousands): As of April 30, 2017 ( unaudited ) Amortized Cost Estimated Fair Value Due within one year $ 2,500 $ 2,500 Due between one to five years — — $ 2,500 $ 2,500 As of January 31, 2017 Amortized Cost Estimated Fair Value Due within one year $ 12,842 $ 12,852 Due between one to five years 1,538 1,538 $ 14,380 $ 14,390

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company measures its financial assets at fair value each reporting period using a fair value hierarchy that prioritizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs maybe used to measure as follows: Level 1-Valuations based on observable inputs that reflect quoted prices for identical assets or liabilities in active markets. Level 2-Valuations based on inputs that are directly or indirectly observable in the marketplace. Level 3-Valuations based on unobservable inputs that are supported by little or no market activity. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table presents information about the Company’s financial assets that are measured at fair value on a recurring basis using the above input categories (in thousands): As of April 30, 2017 ( unaudited ) Level 1 Level 2 Level 3 Total Assets: Cash equivalents: Money market funds $ 217,651 $ — $ — $ 217,651 Short-term investments: Corporate debt securities — 2,500 — 2,500 Total short-term investments — 2,500 — 2,500 Total cash equivalents and short-term investments $ 217,651 $ 2,500 $ — $ 220,151 As of January 31, 2017 Level 1 Level 2 Level 3 Total Assets: Cash equivalents: Money market funds $ 10,565 $ — $ — $ 10,565 Short-term investments: Asset-backed securities — 1,538 — 1,538 Corporate debt securities — 12,852 — 12,852 Total short-term investments — 14,390 — 14,390 Total cash equivalents and short-term investments $ 10,565 $ 14,390 $ — $ 24,955 Liabilities: Series B redeemable convertible preferred stock warrant $ — $ — $ 304 $ 304 Level 3 instruments consist solely of the Company’s Series B redeemable convertible preferred stock warrant liability. During the three months ended April 30, 2017 , the Series B redeemable convertible preferred stock warrant was exercised, the corresponding warrant liability was remeasured to fair value, as recognized in other income (expense), net in the condensed consolidated statements of operations, and reclassified to additional paid-in capital. The change in the fair value of the Series B redeemable convertible preferred stock warrant was as follows (in thousands): Balance at January 31, 2017 $ 304 Increase in fair value of warrant through exercise date 103 Reclassification of remaining warrant liability to additional paid-in capital (407 ) Balance at April 30, 2017 $ — The Company had no transfers between levels of the fair value hierarchy of its assets measured at fair value. The carrying amounts of certain financial instruments, including cash held in banks, accounts receivable, accounts payable and the financing arrangements (see Note 7) approximate fair value due to their short-term maturities and are excluded from the fair value table above.

On June 17, 2015, the Company expanded its line of credit from $5.0 million to $20.0 million and extended the term by one year to mature on March 10, 2017. On November 21, 2016, the Company amended the agreement to extend the maturity date to November 21, 2018 and increase the borrowing capacity of the line of credit (Revolving Line) to $40.0 million . The available amount, not to exceed $40.0 million , is based on certain revenue metrics and is reduced by letters of credit totaling $5.4 million as of April 30, 2017 and January 31, 2017 established in connection with facility lease agreements.

See Note 6 for further details. Equity Incentive Plans The Company has two equity incentive plans: the 2009 Stock Plan (2009 Plan) and the 2017 Equity Incentive Plan (2017 Plan). Upon the completion of the Company’s IPO in April 2017, the 2009 Plan was terminated and all shares that remained available for future issuance under the 2009 Plan at that time were transferred to the 2017 Plan. As of April 30, 2017 , 33,939,472 options to purchase Class B common stock granted under the 2009 Plan remain outstanding. Stock Options A summary of the Company’s stock option activity and related information is as follows: Number of Options Weighted- Average Exercise Price Weighted- Average Remaining Contractual Term (Years) Aggregate Intrinsic Value (in thousands) Outstanding as of January 31, 2017 32,866,862 $ 6.01 8.2 $ 145,570 Granted 2,596,568 11.03 Exercised (1,022,650 ) 2.75 Canceled (501,308 ) 7.53 Outstanding as of April 30, 2017 33,939,472 $ 6.47 8.1 $ 664,506 As of April 30, 2017 Vested and exercisable 12,656,317 $ 3.57 6.8 $ 284,473 The weighted-average grant-date fair value of options granted was $5.36 and $3.65 during the three months ended April 30, 2017 and 2016 , respectively. The aggregate fair value of stock options vested was $4.6 million , and $2.7 million during the three months ended April 30, 2017 and 2016 , respectively. The intrinsic value of the options exercised, which represents the difference between the fair market value of the Company’s common stock on the date of exercise and the exercise price of each option, was $14.1 million and $0.3 million for the three months ended April 30, 2017 and 2016 , respectively. As of April 30, 2017 , there was a total of $75.2 million of unrecognized stock-based compensation expense, which is expected to be recognized over a weighted-average period of 3.1 years . The Company used the Black-Scholes option pricing model to estimate the fair value of stock options granted with the following assumptions: Three Months Ended April 30, 2017 2016 (unaudited) Expected volatility 40.3% - 40.5% 43.4% - 44.3% Expected term (in years) 6.0 - 6.4 5.8 - 6.1 Risk-free interest rate 2.06% - 2.21% 1.29% - 1.54% Expected dividend yield — — Options Subject to Early Exercise Prior to the IPO, at the discretion of the board of directors, certain options were exercisable immediately at the date of grant but subject to a repurchase right, under which the Company may buy back any unvested shares at their original exercise price in the event of an employee’s termination prior to full vesting. The consideration received for an exercise of an unvested option is considered to be a deposit of the exercise price and the related dollar amount is recorded as a liability. The liabilities are reclassified into equity as the awards vest. As of April 30, 2017 and January 31, 2017 , the Company had $2.1 million and $2.2 million , respectively, recorded in accrued expenses and other current liabilities related to early exercises of options to acquire 438,877 and 467,180 shares of Class B common stock, respectively. Restricted Stock Units The Company granted 58,825 RSUs with an aggregate fair value of $1.0 million in the three months ended April 30, 2017 , of which all are outstanding as of April 30, 2017 . As of April 30, 2017 , there was $1.0 million of unrecognized compensation cost related to unvested RSUs, which is expected to be recognized over the next 0.9 years . Equity Awards Issued in Connection with Business Combinations In connection with the Stormpath transaction, the Company issued 800,000 shares of restricted common stock to Stormpath with an aggregate fair value of $8.6 million to be recognized as post combination stock-based compensation. The restricted common stock will vest ratably on the first and second anniversaries of the transaction date upon achievement of the respective performance conditions, including the continued employment of certain employees with the Company and the wind down of the Stormpath, Inc. entity. The stock-based compensation expense related to the restricted common stock will be recognized over two years based on an accelerated attribution method. As of April 30, 2017 , there was $7.4 million of unrecognized compensation expense related to restricted common stock which is expected to be recognized over the remaining weighted average life of 1.8 years. These shares of restricted common stock were separately authorized by the Company’s board of directors, and did not reduce the number of shares available for future issuance under the 2009 Plan or the 2017 Plan. The Company separately entered into retention arrangements with certain employees of Stormpath and issued 598,500 restricted stock awards under the 2009 Plan with an aggregate fair value of $6.6 million with performance conditions, including continued employment of certain employees with the Company and the wind down of the Stormpath, Inc. entity . The restricted stock awards will vest ratably over two or three years from the transaction date. Additionally, the Company granted 518,900 service-based stock options under the 2009 Plan to certain Stormpath employees with an aggregate fair value of $2.5 million to vest ratably over the requisite four -year service period. The restricted stock awards and stock options offered directly to Stormpath employees for employment with the Company are deemed replacement awards and a portion of such awards are considered pre-combination service. Of the $9.1 million total aggregate fair value of the awards, $1.5 million is considered pre-combination service and is recognized as goodwill and a reduction to the post combination compensation expense. The post combination expenses for the restricted stock awards and stock options are $5.5 million and $2.1 million , respectively. The expense related to the restricted stock awards will be recognized over two or three years based on an accelerated attrition method. The expense for the stock options will be recognized ratably over the requisite service period. As of April 30, 2017 , there was $4.8 million of unrecognized compensation expense related to unvested restricted stock awards, which is expected to be recognized over the remaining weighted average life of 2.7 years. As of April 30, 2017 , there was $2.0 million of unrecognized compensation cost related to unvested stock options, which is expected to be recognized over the remaining weighted average life of 3.8 years. The related stock options expense and activity are included within the Stock Options discussions above. All of these shares are outstanding as of April 30, 2017 . Employee Stock Purchase Plan In February 2017, the Company’s board of directors adopted, and in March 2017, the Company’s stockholders approved, the 2017 Employee Stock Purchase Plan, or the ESPP, which became effective prior to the completion of the IPO. The ESPP initially reserves and authorizes the issuance of up to a total of 3,000,000 shares of Class A common stock to participating employees. Except for the initial offering period, the ESPP provides for 12 -month offering periods beginning June 21 and December 21 of each year, and each offering period will consist of two six-month purchase periods. The initial offering period began April 7, 2017 and will end on June 20, 2018. On each purchase date, eligible employees will purchase the shares at a price per share equal to 85% of the lesser of (1) the fair market value of our stock on the offering date or (2) the fair market value of our stock on the purchase date. As of April 30, 2017 , there was $10.4 million of unrecognized stock-based compensation expense related to the ESPP that is expected to be recognized over the remaining term of the initial offering period. The Company estimated the fair value of ESPP purchase rights using a Black-Scholes option pricing model with the following assumptions: Three Months Ended April 30, 2017 (unaudited) Expected volatility 32.8% - 37.4% Expected term (in years) 0.7 - 1.2 Risk-free interest rate 0.95% - 1.08% Expected dividend yield —

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended April 30, 2017 and 2016, the Company recorded a tax provision of $0.2 million and $0.1 million on pretax loss of $28.7 million and $22.7 million , respectively. The effective tax rates for the three month periods ended April 30, 2017 and 2016 were (0.9)% and (0.4)% , respectively. The effective tax rates differ from the statutory rates primarily as a result of providing no benefit on pretax losses incurred in the United States, as the Company has determined that the benefit of the losses is not more likely than not to be realized. The Company adopted ASU 2016-09, Compensation - Stock Compensation (Topic 718), effective February 1, 2017. Upon adoption, the Company recorded a retrospective increase of $0.3 million in gross U.S. deferred tax assets for previously unrecognized excess tax benefits that existed as of January 31, 2017, and a corresponding increase of $0.3 million in valuation allowance against these deferred tax assets, as the Company’s U.S. deferred tax assets are subject to a full valuation allowance. As such, the net impact to the Company’s retained earnings was zero . The adopted guidance requires all of the tax effects related to share-based payments to be recorded through the income statement. The Company’s income tax rate may fluctuate based upon its stock price and the amount of stock options exercised and equity awards vested in a particular quarter.

Summary of Significant Accoun20

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.
