Accounting Policies [Abstract]
Significant Accounting Policies	Note 2. Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the final prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended, on October 6, 2016 (the “Prospectus”). The consolidated financial statements include the results of the Company and its wholly owned subsidiaries. All significant intercompany transactions and balances have been eliminated during consolidation. The condensed consolidated balance sheet as of January 31, 2016, included herein, was derived from the audited financial statements as of that date, but does not include all disclosures including certain notes required by U.S. GAAP on an annual reporting basis. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss and cash flows for the interim periods, but are not necessarily indicative of the results to be expected for the full fiscal year or any other period. There have been no changes to our significant accounting policies described in the Prospectus. Reverse Stock Split Our board of directors and stockholders approved a 1-for-4 reverse stock split of our capital stock, which was effected on September 21, 2016. All references to common stock, options to purchase common stock, restricted stock units, share data, per share data, warrants, convertible preferred stock and related information have been retroactively adjusted where applicable in these condensed consolidated financial statements to reflect the reverse stock split of our capital stock for all periods presented. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. On an ongoing basis, management evaluates its significant estimates including the valuation of accounts receivable, the lives of tangible and intangible assets, stock-based compensation, stock warrants, revenue recognition, the valuation of acquired intangible assets, and provisions for income taxes. Management bases its estimates on historical experience and on various other market-specific and relevant assumptions that management believes to be reasonable under the circumstances. Actual results could differ from those estimates and such differences could be material to the financial position and results of operations. Comprehensive Loss Comprehensive loss is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. The Company’s comprehensive loss is composed only of net loss. Recently Adopted Accounting Pronouncements In September 2015, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments There was no material impact due to the adoption of this new standard. In April 2015, the FASB issued ASU No. 2015-05, Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement (“ASU 2015-05”) There was no material impact due to the adoption of this new standard. In August 2014, the FASB issued ASU No. 2014-15, Disclosures of Uncertainties About an Entity’s Ability to Continue as a Going Concern There was no material impact due to the adoption of this new standard. New Accounting Pronouncements Not Yet Adopted In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers Revenue Recognition Revenue Recognition-Construction-Type and Production-Type Contracts In February 2016, the FASB issued ASU No. 2016-02, Leases In March 30, 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 3 . Fair Value Measurements Fair value is the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Subsequent changes in fair value of these financial assets and liabilities are recognized in earnings or other comprehensive income when they occur. When determining the fair value measurements for assets and liabilities which are required to be recorded at fair The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: • Level 1—Quoted prices in active markets for identical assets or liabilities. • Level 2—Observable inputs other than quoted price in active markets for identical assets or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially full term of assets or liabilities. • Level 3—Inputs that are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the assets or liabilities. The following table summarizes the Company’s fair value hierarchy for its financial assets and liabilities measured at fair value on a recurring basis (in thousands): October 31, 2016 Level 1 Level 2 Level 3 Total Financial assets: Money market funds $ 50,179 $ - $ - $ 50,179 Financial liabilities: Preferred stock warrant liability $ - $ - $ 874 $ 874 January 31, 2016 Financial assets: Money market funds $ 50,044 $ - $ - $ 50,044 Financial liabilities: Preferred stock warrant liability $ - $ - $ 247 $ 247 The following table represents the change in the fair value of the preferred stock warrant liability (in thousands): Balance at January 31, 2016 247 Change in fair value 627 Balance at October 31, 2016 $ 874

Share-Based Compensation	Note 6 . Share-Based Compensation 2016 Equity Incentive Plan The 2016 Equity Incentive Plan, or 2016 Plan, was approved by our stockholders in September 2016. The 2016 Plan provides for the grant of incentive stock options, nonstatutory stock options, restricted stock, restricted stock units, stock appreciation rights and performance cash awards. Awards could be granted under the 2016 Plan beginning on the effective date of the registration statement, October 5, 2016. The 2016 Plan replaced our 2006 Stock Plan, however awards outstanding under the 2006 Stock Plan will continue to be governed by their existing terms. We have reserved 4,500,000 shares of our common stock for issuance under the 2016 Plan, plus up to 13,750,000 shares subject to awards outstanding under our 2006 Plan on October 5, 2016, that subsequently expire, lapse unexercised, are forfeited or are repurchased by us. The number of shares reserved for issuance under the 2016 Plan will automatically increase on the first day of each fiscal year during the term of the 2016 Plan by a number of shares equal to 5% of our outstanding shares of common stock on the last day of the prior fiscal year. The number and class of shares reserved under the 2016 Plan will be adjusted in the event of a stock split, stock dividend or other changes in our capitalization. The following table summarizes stock option activity under the 2006 Stock Plan and the 2016 Plan during the nine months ended October 31, 2016 (aggregate intrinsic value in thousands): Options Outstanding Outstanding Stock Options Weighted- Average Exercise Price Weighted- Average Remaining Contractual (in years) Aggregate Intrinsic Value Balance, January 31, 2016 9,543,966 $ 2.84 8.08 $ 47,658 Option grants 5,466,096 $ 9.40 Options exercised (1,056,220 ) $ 3.88 Options forfeited (759,070 ) $ 4.14 Balance, October 31, 2016 13,194,772 $ 5.40 8.14 $ 258,575 Vested and expected to vest at October 31, 2016 12,044,335 $ 5.13 8.05 $ 239,320 Exercisable at October 31, 2016 6,416,080 $ 3.37 7.26 $ 138,797 The options exercisable as of October 31, 2016 include options that are exercisable prior to vesting. The aggregate intrinsic value of options vested and expected to vest and exercisable as of October 31, 2016 is calculated based on the difference between the exercise price and the fair value of the Company’s common stock as of October 31, 2016. Prior to the IPO, the fair value of the Company’s common stock was estimated by the Company’s board of directors. After the IPO, the fair value of the common stock is the Company’s closing stock price as reported on the Nasdaq Global Select Market. The aggregate intrinsic value of exercised options was $5.8 million and $8.0 million for the three and nine months ended October 31, 2016, respectively, and $0.2 million and $3.6 million for the three and nine months ended October 31, 2015, respectively, and is calculated based on the difference between the exercise price and the fair value of the Company’s common stock as of the exercise date. The weighted-average grant date fair value of options granted during the three and nine months ended October 31, 2016 was $6.16 and $4.48 per share, respectively, and $2.57 and $2.16 per share, for the three and nine months ended October 31, 2015, respectively. During the three and nine months ended October 31, 2016, 31,250 and 83,500 options were granted to non-employees, respectively. During the three and nine months ended October 31, 2015, 20,000 and 25,000 options were granted to non-employees, respectively. Early Exercises of Stock Options Certain option grants under the 2006 Stock Plan are allowed to be exercised prior to vesting. The unvested shares of common stock exercised are subject to the Company’s right to repurchase at the lower of the original exercise price or the fair market value of the share at the time the repurchase right is exercised. Early exercises of options are not deemed to be substantive exercises for accounting purposes and accordingly, amounts received for early exercises are initially recorded in accrued expenses and other current liabilities and reclassified to additional paid-in capital as the underlying shares vest. At January 31, 2016 and October 31, 2016, the Company had $1.1 and $2.8 million, respectively, recorded in accrued expenses and other current liabilities related to early exercises of stock options, and the related number of unvested shares subject to repurchase was 208,008 and 284,959, respectively. RSUs The following table summarizes the activity related to the Company’s RSUs: Number of RSU's Outstanding Weighted-Average Grant Date Fair Value Awarded and unvested at January 31, 2016 62,500 $ 5.20 Awards granted - $ - Awards vested (23,828 ) $ 5.36 Awards forfeited (6,250 ) $ 3.92 Awarded and unvested at October 31, 2016 32,422 $ 5.36 2016 Employee Stock Purchase Plan Our board of directors adopted the 2016 Employee Stock Purchase Plan, or ESPP, in September 2016 and it has been approved by our stockholders. The ESPP allows eligible employees to purchase shares of our common stock through payroll deductions and is intended to qualify under Section 423 of the Internal Revenue Code. We have reserved 818,750 shares of our common stock for issuance under the ESPP. The number of shares reserved for issuance under the ESPP will automatically increase on the first day of each fiscal year during the term of the ESPP by a number of shares equal to the least of (i) 1% of our outstanding shares of common stock on the last day of the prior fiscal year, (ii) 1,250,000 shares or (iii) a lesser number of shares determined by our board of directors. The number and class of shares reserved under the ESPP will be adjusted in the event of a stock split, stock dividend or other changes in our capitalization. Each offering period will last a number of months determined by the administrator, up to a maximum of 27 months. The initial offering period began on the effective date of our IPO, October 5, 2016, and ends on September 15, 2018, and new 24 month offering periods will begin on each March 16 and September 16 thereafter. Currently each offering period consists of 4 consecutive purchase periods, of approximately 6 months duration, at the end of which payroll contributions are used to purchase shares of our common stock. Participants may purchase our common stock through payroll deductions, up to a maximum of 15% of their eligible compensation. Participants may withdraw from the ESPP and receive a refund of their accumulated payroll contributions at any time prior to a purchase date. Unless changed by the administrator, the purchase price for each share of our common stock purchased under the ESPP will be 85% of the lower of the fair market value per share on the first day of the applicable offering period (or, in the case of the initial offering period, the price at which one share of common stock is offered to the public in this offering) or the fair market value per share on the applicable purchase date. For the three months and nine months ended October 31, 2016, no shares of common stock were purchased under the 2016 ESPP and 845,645 shares are expected to be purchased at the end of the initial offering period. The Company selected the Black-Scholes option-pricing model as the method for determining the estimated fair value for the Company’s 2016 ESPP. As of October 31, 2016, total unrecognized compensation cost related to 2016 ESPP was $9.4 million, net of estimated forfeitures, which will be amortized over a weighted-average period of 1.87 years. Market-based Options In September 2016, the Board of Directors of the Company granted 544,127 stock options to the Chief Executive Officer (2016 CEO Grant) under the 2006 Equity Plan with an exercise price of $13.04 per share is eligible to vest based on the achievement of stock price appreciation targets after the consummation of the initial public offering, as well as continuous service over a four year period following the grant date. Stock-based Compensation The Company’s total stock-based compensation expense was as follows as the dates specified (in thousands): Three months ended Nine months ended October 31, October 31, 2016 2015 2016 2015 Cost of revenue: Subscription services 150 62 415 161 Professional services and other 155 59 399 944 Research and development 357 152 982 1,009 Sales and marketing 937 706 1,848 1,092 General and administrative 785 547 2,005 6,353 Total 2,384 1,526 5,649 9,559 Of the total stock-based compensation expenses, costs recognized for options granted to non-employees were immaterial for all periods presented. As of October 31, 2016 there was approximately $23.5 million of total unrecognized compensation cost related to unvested stock options granted to employees and non-employee service providers under the 2006 Stock Plan and 2016 Equity Incentive Plan. This unrecognized compensation cost is expected to be recognized over an estimated weighted-average amortization period of approximately 2.85 years. Prior to October 5, 2016, the Company did not recognize stock-based compensation expense for the RSUs previously granted under its 2006 Plan to its employees because the qualifying events for the awards vesting were not probable. The qualifying events for the awards were satisfied upon occurrence of the Company’s IPO in October 2016. As of July 31, 2016 the Company had deferred recognition of $230,000 of cumulative share-based compensation expense related to these RSUs for which the service condition was satisfied, after giving effect to estimated forfeitures. This amount was recorded into the quarterly period ended October 31, 2016. The fair values of the Company’s stock options granted during the three months ended October 31, 2016 and 2015 and during the nine months ended October 31, 2016 and 2015 was estimated using the following assumptions: Three months ended Nine months ended October 31, October 31, 2016 2015 2016 2015 Employee Stock Options Expected term (years) 6.00 5.70 - 6.00 6.00 5.70 - 6.00 Volatility 48% 48% 48% 48% Weighted average volatility 48% 48% 48% 48% Risk-free interest rate 1.27% - 1.33% 1.62% - 1.68% 1.27% - 1.55% 1.62% - 1.94% Dividend yield 0% 0% 0% 0% Employee Stock Purchase Plan Expected term (years) 0.41 - 1.91 - 0.41 - 1.91 - Volatility 48% - 48% - Weighted average volatility 48% - 48% - Risk-free interest rate 0.48% - 0.81% - 0.48% - 0.81% - Dividend yield 0% - 0% - Market-Based Options Expected term (years) 10.00 - 10.00 - Volatility 48% - 48% - Weighted average volatility 48% - 48% - Risk-free interest rate 1.61% - 1.61% - Dividend yield 0% - 0% -

Although the results of litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of these ordinary course matters will not have a material adverse effect on the Company’s business, operating results, financial condition or cash flows. Regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources and other factors. Warranties and Indemnifications The Company’s cloud-based software platform and applications are typically warranted to perform in a manner consistent with general industry standards and in accordance with the Company’s on-line documentation under normal use and circumstances.

Income Tax Disclosure [Abstract]
Income Taxes	Note 9 . Income Taxes The Company is subject to Federal and various state income taxes in the United States as well as other foreign jurisdictions in which it conducts business. Earnings from non-U.S. activities are subject to local country income tax. The Company does not provide for federal income taxes on the undistributed earnings of its foreign subsidiaries as such earnings are reinvested indefinitely. In accordance with applicable accounting guidance, the income tax provision for the three and nine months ended October 31, 2016 is based on the estimated annual effective tax rate for fiscal year 2017. The estimated effective tax rate may be subject to adjustment in subsequent quarterly periods as the estimates of pretax income for the year, along with other items that may affect the rate, change. The Company recorded a tax provision of $211,000 and $502,000 for the three and nine months ended October 31, 2016 as compared to $75,000 and $200,000 in the same prior year periods, representing effective tax rates of (1.67)% and (0.58)% for the nine month periods ending October 31, 2016 and October 31, 2015, respectively. The difference between the U.S. federal statutory tax rate of 34% and our effective tax rate in all periods is primarily due to a full valuation allowance related to the Company’s U.S. Federal and state and Canada deferred tax assets offset by foreign tax expense on the Company’s profitable foreign operations. The Company's policy is to include interest and penalties related to income tax liabilities with the provision for income taxes on the consolidated statements of income. The Company reported an immaterial amount for interest and penalites for the nine months ended October 31, 2016, as compared to none in the same prior year period. The Company's material income tax jurisdictions are the United States (federal) and California. As a result of net operating loss carryforwards, the Company is subject to audit for tax years 2007 and forward for federal purposes and 2010 and forward for California purposes. There are tax years which remain subject to examination in various other jurisdictions that are not material to the Company's financial statements.

Earnings Per Share [Abstract]
Net Loss per Share Attributable to Common Stockholders	Note 10 . Net Loss per Share Attributable to Common Stockholders 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, without consideration for potentially dilutive securities as they do not share in losses. During periods when the Company is in a net loss position, basic net loss per share attributable to common stockholders is the same as diluted net loss per share attributable to common stockholders as the effects of potentially dilutive securities are antidilutive given the net loss of the Company. The following table sets forth the computation of the basic and diluted net loss per share attributable to common stockholders during the three months ended October 31, 2016 and 2015 and for the nine months ended October 31, 2016 and 2015 (in thousands, except per share amounts): Three months ended Nine months ended October 31, October 31, 2016 2015 2016 2015 Numerator: Net loss attributable to common stockholders $ (6,694 ) $ (9,518 ) $ (30,999 ) $ (34,665 ) Denominator: Weighted-average common shares outstanding 18,420 4,901 9,987 4,537 Net loss per share attributable to common stockholders, basic and diluted $ (0.36 ) $ (1.94 ) $ (3.10 ) $ (7.64 ) Since the Company was in a loss position for all periods presented, basic net loss per share attributable to common stockholders is the same as diluted net loss per share for all periods as the inclusion of all potential common shares outstanding would have been anti-dilutive. Potentially dilutive securities that were not included in the diluted per share calculations because they would be anti-dilutive were as follows: As of October 31, 2016 2015 Convertible preferred stock as converted - 34,610,979 Options to purchase common stock 13,194,772 9,588,244 RSUs 32,422 62,500 Unvested common shares subject to repurchase 322,473 133,397 Shares committed under 2016 ESPP 16,828 - Convertible preferred stock warrants 36,971 36,971 Total 13,603,466 44,432,091

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the final prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended, on October 6, 2016 (the “Prospectus”). The consolidated financial statements include the results of the Company and its wholly owned subsidiaries. All significant intercompany transactions and balances have been eliminated during consolidation. The condensed consolidated balance sheet as of January 31, 2016, included herein, was derived from the audited financial statements as of that date, but does not include all disclosures including certain notes required by U.S. GAAP on an annual reporting basis. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss and cash flows for the interim periods, but are not necessarily indicative of the results to be expected for the full fiscal year or any other period. There have been no changes to our significant accounting policies described in the Prospectus.
Reverse Stock Split	Reverse Stock Split Our board of directors and stockholders approved a 1-for-4 reverse stock split of our capital stock, which was effected on September 21, 2016. All references to common stock, options to purchase common stock, restricted stock units, share data, per share data, warrants, convertible preferred stock and related information have been retroactively adjusted where applicable in these condensed consolidated financial statements to reflect the reverse stock split of our capital stock for all periods presented.
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 reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. On an ongoing basis, management evaluates its significant estimates including the valuation of accounts receivable, the lives of tangible and intangible assets, stock-based compensation, stock warrants, revenue recognition, the valuation of acquired intangible assets, and provisions for income taxes. Management bases its estimates on historical experience and on various other market-specific and relevant assumptions that management believes to be reasonable under the circumstances. Actual results could differ from those estimates and such differences could be material to the financial position and results of operations.
Comprehensive Loss	Comprehensive Loss Comprehensive loss is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. The Company’s comprehensive loss is composed only of net loss.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In September 2015, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments There was no material impact due to the adoption of this new standard.
