Accounting Policies [Abstract]
Description of Business and Significant Accounting Policies	Description of Business and Significant Accounting Policies Description of Business Apigee Corporation’s (together with its wholly-owned subsidiaries, “Apigee” or the “Company”) mission is to make every business a digital business. The Company provides an innovative software platform that allows businesses to design, deploy, and scale APIs, as a connection layer between their core IT systems and data and the applications with which their customers, partners, employees and other users engage with the business. The foundations of the Company’s platform are Apigee Edge, a robust API-management solution, and Apigee Insights, the Company’s predictive analytics software solution. The Company delivers its platform both in the cloud and on premises. Apigee was incorporated in Delaware on June 3, 2004 and is headquartered in San Jose, California. Initial Public Offering On April 29, 2015 the Company completed its initial public offering (the “IPO”) in which it sold 5,115,000 shares of common stock to the public at $17.00 per share. The total gross proceeds from the offering were approximately $87.0 million . After deducting underwriting discounts and commissions and offering expenses payable by the Company, the aggregate net proceeds received totaled approximately $76.9 million . The sale of common stock in the IPO triggered the weighted average anti-dilution provisions of the Company’s amended and restated certificate of incorporation then in effect. At the IPO price of $17.00 per share, the per share conversion rate for the Company’s Series H convertible preferred stock into common stock was approximately 1: 1.0365 . In connection with the completion of the IPO, and giving effect to the anti-dilution adjustment relating to the Company’s Series H convertible preferred stock, all shares of the Company’s convertible preferred stock outstanding automatically converted into 19,818,172 shares of the Company’s common stock. Reverse Stock Split On April 7, 2015, the Company effected a 1-for-7.6 reverse stock split of its common stock and convertible preferred stock, as approved by its Board of Directors (the “Board”) and stockholders. All information throughout these consolidated financial statements and notes to the consolidated financial statements relating to the number of shares, price per share and per share amounts have been adjusted to give effect to the 1-for-7.6 reverse stock split. All fractional shares were settled in cash. Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”). The accompanying consolidated financial statements include the accounts of Apigee Corporation and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated upon consolidation. 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 at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period covered by the consolidated financial statements and accompanying notes. In particular, the Company makes estimates with respect to the fair value of multiple elements in revenue recognition, uncollectible accounts receivable, assets acquired and liabilities assumed in a business combination, valuation of long-lived assets, stock-based compensation, income taxes and other contingencies. Actual results could differ from those estimates and such differences could be material to the financial statements and affect the results of operations reported in future periods. Foreign Currency Transactions The functional currency of the Company’s foreign subsidiaries is the U.S. dollar. Accordingly, monetary balance sheet accounts are remeasured using the current exchange rate in effect at the balance sheet date and non-monetary items are remeasured at the historical exchange rate. Expenses are remeasured at the average exchange rates for the period. The resulting gains and losses are included in other expense, net and were not material for the years ended July 31, 2016 , 2015 and 2014 . Cash and Cash Equivalents The Company considers all highly liquid instruments with original or remaining maturities of 90 days or less at the date of purchase to be cash equivalents. Cash and cash equivalents are stated at cost, which approximates fair value. As of July 31, 2016 and 2015 , $66.0 million and $86.4 million , respectively, of cash and cash equivalents were invested in money market funds. Concentration of Risk and Significant Customers Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company maintains the majority of its cash and money market accounts at one financial institution that management believes is a high-credit, high-quality financial institution and accordingly, subject to minimal credit risk. Deposits held with these financial institutions may be in excess the amount of insured limits provided on such deposits, if any. The Company’s accounts receivable are subject to credit risks. The accounts receivable are unsecured and are derived from customers around the world in a variety of industries. The Company’s significant customers who individually exceeded 10% of total accounts receivable as of the dates shown or total revenue during the period are as follows: Revenue Accounts Receivable Year Ended July 31, As of July 31, 2016 2015 2014 2016 2015 Customer A * * 15% * * Customer B * * * 11% * * Does not exceed 10%. Accounts Receivable and Allowance for Doubtful Accounts The Company’s accounts receivable are recorded at invoiced amounts, net of the Company’s estimated allowances for doubtful accounts. The allowance for doubtful accounts is estimated based on an assessment of the Company’s ability to collect on customer accounts receivable. The Company performs ongoing credit evaluations of its customers and regularly reviews the allowance by considering certain factors such as historical experience, industry data, credit quality, age of accounts receivable balances and current economic conditions that may affect a customer’s ability to pay. In cases where the Company is aware of circumstances that may impair a specific customer’s ability to meet their financial obligations, the Company records a specific allowance against amounts due from the customer and thereby reduces the net recognized receivable to the amount the Company reasonably believes will be collected. There is judgment involved with estimating the Company’s allowance for doubtful accounts and if the financial condition of its customers were to deteriorate, resulting in their inability to make the required payments, the Company may be required to record additional allowances or charges against revenue. The Company writes off accounts receivable against the allowance when it determines a balance is uncollectible and no longer actively pursues collection of the receivable. The Company’s accounts receivable are not collateralized by any security. The following table summarizes the accounts receivable allowance activity: Year Ended July 31, 2016 2015 2014 (in thousands) Balance at beginning of period $ 89 $ 204 $ 172 Additions 132 42 150 Write-offs, net of recoveries (146 ) (157 ) (118 ) Balance at end of period $ 75 $ 89 $ 204 Property and Equipment, Net Property and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets generally ranging from three to five years . Leasehold improvements are amortized over the shorter of the estimated useful life or the remaining lease term. When assets are retired or disposed of, the cost and accumulated depreciation are removed from the accounts, and any resulting gains or losses are included in the consolidated statements of comprehensive loss. Maintenance and repairs that do not improve or extend the lives of the respective assets are expensed in the period incurred. The estimated useful lives of property and equipment are as follows: Useful Life Computer equipment and software 3 years Furniture and fixtures 5 years Leasehold improvements Shorter of the lease term or estimated useful life Fair Value of Financial Instruments Assets and liabilities recorded at fair value in the financial statements are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels which are directly related to the amount of subjectivity associated with the inputs to the valuation of these assets or liabilities are as follows: Level 1—Observable inputs, such as quoted prices in active markets for identical assets or liabilities. Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company has certain financial assets and liabilities that are measured at fair value on a recurring basis. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and considers factors specific to the asset or liability. The Company’s cash equivalents include highly liquid money market funds and are classified within the Level 1 of the fair value hierarchy. Level 3 liabilities that are measured at fair value on a recurring basis consist solely of the Company’s common stock warrant liability. The fair values of the outstanding common stock warrants are measured using the Black-Scholes option-pricing model. Inputs used to determine estimated fair value include the estimated fair value of the underlying stock at the valuation measurement date, the remaining contractual term of the warrants, risk-free interest rates, expected dividends, and the expected volatility of the underlying stock. Generally, increases (decreases) in the fair value of the underlying stock and estimated term would have a directionally similar impact to the fair value measurement. The carrying amounts of certain of the Company’s financial instruments including cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair value due to their short-term maturities. Based on borrowing rates currently available to the Company for financing obligations with similar terms and considering the Company’s credit risks, the carrying value of the Company’s long-term debt approximates fair value. Goodwill and Intangible Assets Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired in a business combination. Goodwill is not amortized, but is tested for impairment at least annually or more frequently if events or changes in circumstances indicate that the asset may be impaired. The Company’s impairment tests are based on a single operating segment and reporting unit structure. If the Company determines that it is more likely than not that the fair value of the Company’s reporting unit is less than the carrying value, it will conduct a two-step test for impairment of goodwill. The first step involves comparing the fair value of the Company’s reporting unit to its carrying value, including goodwill. If the carrying value of the reporting unit exceeds its fair value, the second step of the test is performed by comparing the carrying value of the goodwill in the reporting unit to its implied fair value. An impairment charge is recognized for the excess of the carrying value of goodwill over its implied fair value. The Company’s annual goodwill impairment test resulted in no impairment charges during the years ended July 31, 2016 , 2015 or 2014 . Intangible assets acquired as part of a business combination, consisting primarily of developed technology, customer relationships and backlog are capitalized at their acquisition-date fair value and amortized using the straight-line method over their estimated useful life. Impairment of Long-lived Assets Long-lived assets, such as property, plant, and equipment, and purchased intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of these assets is measured by a comparison of the future undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. There were no impairment charges for the years ended July 31, 2016 , 2015 and 2014 . Business Combinations The Company recognizes assets acquired, liabilities assumed and contingent consideration at their fair value on the acquisition date. The Company’s estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company’s consolidated statements of comprehensive loss. In addition, uncertainties in income tax and tax related valuation allowances assumed in connection with a business combination are initially estimated as of the acquisition date. The Company continues to gather information and evaluates these items and records any adjustments to the Company’s preliminary estimates to goodwill when the Company is within the measurement period. Subsequent to the measurement period, changes to these income tax uncertainties and tax related valuation allowances will affect the Company’s provision for income taxes in the Company’s consolidated statements of comprehensive loss. Capitalized Software Development Costs Software development costs are expensed as incurred until the establishment of technological feasibility, at which time those costs are capitalized until the product is available for general release to customers and amortized over the estimated life of the product. Technological feasibility is established upon completion of a working model. To date, costs incurred subsequent to the establishment of technological feasibility have not been significant, and all software development costs have been charged to research and development expense in the accompanying consolidated statements of comprehensive loss. Revenue Recognition The Company generates revenue from the sale of its software solutions to customers through perpetual licenses and time-based licenses for its on premises solutions, and subscription arrangements for its cloud service. The Company also generates revenue from the sale of post-contract software support for on premises licenses including when and if available updates, and professional services such as consulting and training services. The Company recognizes revenue when all of the following conditions are met: • persuasive evidence of an arrangement exists; • delivery has occurred or services have been provided; • sales price is fixed or determinable; and • collection of the related receivable is probable. Signed agreements, including by electronic acceptance, are used as evidence of an arrangement. For the Company’s on premises solution, delivery is considered to occur when it provides the customer the ability to download the software. For the Company’s cloud service solution, delivery is considered to occur when a subscription service is provisioned and made available to a customer. The Company assesses whether a fee is fixed or determinable at the outset of the arrangement, primarily based on the payment terms associated with the sale. The Company assesses collectability of the fee based on a number of factors such as collection history and creditworthiness of the customer. If the Company determines that collectability is not probable, revenue is deferred until collectability becomes probable, generally upon receipt of payment from the customer. The Company typically enters into multiple-element arrangements with its customers in which a customer may purchase a combination of its software (offered on premises with software support or as a cloud service) solution, and professional services. The software support and professional services are not considered essential to the functionality of the software. All of these elements are considered separate units of accounting. Typically, the Company’s agreements do not include rights for customers to cancel or terminate arrangements or to return software to obtain refunds. The Company presents revenue on a net basis, and therefore, all sales taxes are excluded from revenue in the consolidated statements of comprehensive loss. Travel and other reimbursable costs are recorded in revenue. License License revenue is comprised of revenue generated from licenses of the Company’s on premises perpetual and time-based software solutions. The majority of the Company’s perpetual software license arrangements include a combination of the Company’s software downloaded on the customer’s hardware, software support, or professional services. For software elements, under the software revenue recognition guidance, the residual method is used to recognize revenue when a multiple-element arrangement includes one or more elements to be delivered at a future date and vendor-specific objective evidence (“VSOE”) of fair value of all undelivered element exists. VSOE is defined as the price charged when the same element is sold separately or for an element not yet being sold separately, the price established by management having relevant authority. In the majority of the Company’s software arrangements, the only element that remains undelivered at the time of delivery of the software product is software support or services. The Company has established VSOE for consulting days, training and software support, except for software support bundled with time-based licenses, based on a substantial majority of separate stand-alone sales of these elements, which have been priced within a reasonably narrow range. As a result, for multiple element arrangements that include perpetual licenses, revenue is allocated to the undelivered elements based on VSOE for support or consulting days and training. Using the residual method, the difference between the total arrangement fee and amount deferred for the undelivered elements is recognized upon delivery of the perpetual license if all other revenue recognition criteria are met. The Company does not have VSOE for software support bundled with time-based licenses. Therefore, revenue from time-based licenses to the Company’s on-premises solution is generally recognized ratably over the contractual term for all periods presented. Subscription and Support Subscription and support revenue includes the revenue derived from customer subscriptions to the Company’s cloud service and software support for its on premises software licenses. Cloud service arrangements generally include the Company’s cloud service solution offered on a subscription basis and professional services. The term of the arrangement allows for the customer to access the Company’s software for a specified period of time, generally one to three years . In cloud service subscription arrangements, the customer is not allowed to take possession of the Company’s software. Revenue from subscriptions to the Company’s cloud service is generally recognized ratably over the contractual term for all periods presented. When cloud service subscription arrangements involve multiple elements that qualify as separate units of accounting (i.e., the delivered items have stand-alone value), the Company allocates arrangement consideration based on the relative selling price method using the following selling price hierarchy: (1) VSOE if available; (2) third-party evidence (“TPE”), if VSOE is not available; and (3) best estimate of selling price (“BESP”) if neither VSOE nor TPE is available. The Company has not historically priced its cloud service solution within a narrow range and, therefore, cannot establish VSOE. The Company also believes that TPE is not readily available for its cloud service as pricing is not readily accessible and there is no comparable product offering in the market. As a result, the Company uses BESP in order to allocate the selling price to cloud deliverables. The Company determines BESP considering multiple factors including, but not limited to, the price it charges for similar offerings, market conditions, competitive landscape, and pricing practices. For cloud offerings that include consulting days and training, the Company uses BESP for cloud deliverables and VSOE for consulting days and training to allocate revenue into separate units of accounting. Revenue for the cloud service is generally recognized over the subscription period when all other revenue recognition criteria are met. Consulting days and training are recognized as the services are performed, as discussed below. Revenue from software support for the Company’s on-premises perpetual and time-based software licenses is generally recognized ratably over the contractual term, which is typically one to three years . Software support is bundled with time-based licenses and the Company uses a consistent systematic and rational method to allocate between time-based license and support revenue for financial statement presentation purposes only. Professional Services and Other Generally, the Company’s professional service arrangements are short-term in nature and not considered essential to the functionality of the Company’s software. Professional services are generally offered as consulting days, time and material and fixed-fee arrangements. Consulting days are recognized as revenue as the services are performed on an hourly basis or upon expiration of the service period. Time and material services are recognized as revenue as services are rendered based on inputs to the project, such as billable hours incurred. For fixed-fee professional service arrangements, the Company recognizes revenue under the proportional performance method of accounting and estimates the proportional performance on a monthly basis, utilizing hours incurred to date as a percentage of the total estimated hours to complete the project. In cases where the Company has on premises perpetual or time-based license and professional services arrangements requiring significant customization and implementation that are considered essential to the functionality of the software, the arrangement is accounted for using contract accounting until the essential services are complete. If the Company can make reliable estimates of total project costs and the extent of progress toward completion, it applies the percentage-of-completion method in recognizing the arrangement fee. Deferred Revenue Deferred revenue primarily consists of billings or payments received in advance of revenue recognition from the Company’s product offerings described above and is recognized as the revenue recognition criteria are met. Deferred revenue that will be recognized during the following 12 months is recorded as a current liability and the remaining portion is recorded as non-current. Deferred Cost of Revenue Deferred cost of revenue primarily consists of direct costs for professional services from multiple-element arrangements either accounted for using the completed contract method or subject to acceptance. The direct costs are being recognized in proportion to the related revenue. Product Warranties The Company generally provides a warranty for its software products and services to its customers for periods ranging from one to six months . The Company’s software products are generally warranted to be free of defects in materials and workmanship under normal use and the products are also generally warranted to substantially perform as described in published documentation. The Company’s services are generally warranted to be performed in a professional manner and to materially conform to the specifications set forth in the related customer contract. In the event there is a failure of such warranties, the Company generally will correct the problem or provide a reasonable workaround or replacement product. If the Company cannot correct the problem or provide a workaround or replacement product, then the customer’s remedy is generally limited to refund of the fees paid for the nonconforming product or services. To date, the warranty expenses have been insignificant. Sales Commissions Sales commissions are recorded as a component of sales and marketing expenses and consist of the variable compensation paid to the Company’s sales force. Sales commissions are earned and recorded at the time that a customer has entered into a binding license, subscription or services agreement. Sales commission expense was $7.2 million, $7.1 million and $4.6 million for the years ended July 31, 2016 , 2015 and 2014 , respectively. Research and Development Research and development costs are expensed as incurred, except for certain internal-use software development costs, which may be capitalized as noted above. Advertising The Company expenses advertising costs as incurred as a component of sales and marketing expenses. The Company incurred advertising costs of zero , $0.1 million and $0.2 million for the years ended July 31, 2016 , 2015 and 2014 , respectively. Stock-based Compensation The Company recognizes compensation expense for all stock-based awards, including stock options, ESPP and restricted stock units (“RSUs”), based on the estimated fair value of the award on the grant date in the consolidated statements of comprehensive loss over the related vesting periods. The expense recorded is based on awards ultimately expected to vest and therefore is reduced by estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company calculates the fair value of awards using the Black-Scholes option pricing model and records expense using the straight-line attribution approach. The determination of the grant date fair value of awards is affected by a number of complex variables, which include the Company’s fair value of common stock, expected term of the options, expected volatility, risk-free interest rates and expected dividends. Prior to the Company's IPO, the Company engaged an outside expert to assist management with the valuation of the Company's common stock grants. The Company accounts for equity awards issued to non-employees, such as consultants, in accordance with the guidance relating to equity instruments that are issued to other than employees for acquiring, or in conjunction with selling, goods or services, using the Black-Scholes option pricing model to determine the fair value of such instruments. Awards granted to non-employees are remeasured over the vesting period, and the resulting value is recorded as an expense over the period the services are received. Segments The Company operates its business as one operating segment. The Company’s chief operating decision maker is its Chief Executive Officer, who reviews financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance and allocating resources. Taxes Income Taxes The Company accounts for income taxes using the asset and liability approach. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company evaluates the realizability of its deferred income tax assets and assesses the need for a valuation allowance on an ongoing basis. In evaluating its deferred income tax assets, the Company considers all available positive and negative evidence related to the likelihood of realization of the deferred tax assets to determine, based on the weight of available evidence, whether it is more likely than not that some or all of the deferred tax assets will not be realized. The Company has recorded a full valuation allowance on its U.S. deferred tax assets as of July 31, 2016 because the realization of these tax benefits through future taxable income is not more likely than not as of July 31, 2016 . The valuation allowance will be maintained until sufficient positive evidence exists to support the reversal of the valuation allowance. The Company makes estimates and judgments about its future taxable income that are based on assumptions that are consistent with the plans and estimates. Should the actual amounts differ from the estimates, the amount of the valuation allowance could be materially impacted. The Company accounts for uncertain tax positions using a two-step approach for recognizing and measuring uncertain tax positions. Tax positions are evaluated for recognition by determining if the weight of available evidence indicates that it is probable that the position will be sustained on audit, including resolution of related appeals or litigation. Tax benefits are then measured as the largest amount which is more than 50% likely of being realized upon ultimate settlement. The Company considers many factors when evaluating and estimating tax positions and tax benefits, which may require periodic adjustments and which may not accurately anticipate actual outcomes. The Company recognized potential accrued interest and penalties related to unrecognized tax benefits in tax expense. Other Taxes The Company conducts operations in many tax jurisdictions throughout the U.S and around the world. In many of these jurisdictions, non-income based taxes such as property taxes, sales and use taxes, and value-added taxes are assessed on the Company’s operations in that particular location. While the Company strives to ensure compliance with these various non-income based tax filing requirements, there have been instances where potential non-compliance exposures have been identified. In accordance with GAAP, the Company makes a provision for these exposures when it is both probable that a liability has been incurred and the amount of the exposure can be reasonably estimated. The Company believes that, as of July 31, 2016 and 2015 , it has adequately provided for such contingencies. However, it is possible that the Company’s results of operations, cash flows, and financial position could be harmed if one or more non-compliance tax exposures are asserted by any of the jurisdictions where the Company conducts its operations. Commitments and Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when it is probable that a liability has been or will be incurred and the amount of the liability can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred. Recently Adopted Accounting Standards Share-Based Payments with Performance Targets: In June 2014, the FASB issued Accounting Standards Update No.

Equity [Abstract]
Common Stock Warrants	Common Stock Warrants The Company has not issued any new warrants in fiscal 2016. As of July 31, 2016 and July 31, 2015 , 3,495 warrants to purchase shares of common stock issued to Silicon Valley Bank in fiscal 2015 with an exercise price of $13.68 remained exercisable. On February 14, 2013, the Company issued to one of its customers a warrant to purchase 420,901 shares of common stock with an exercise price of $1.52 per share. The warrant was provided as a sales incentive and recorded as an offset to the amount of revenue recognized from the customer. The warrant vested 50% upon achievement of each of two performance milestones. Both performance milestones were based on achieving certain targets and both were met as of July 31, 2013. The warrant agreement had an anti-dilution clause whereby, if a financing event occurred prior to December 31, 2013, the Company was obligated to issue additional warrants to the customer equal to 2% of the Company’s outstanding shares on a fully diluted basis. A financing event was defined as a sale of equity securities for capital raising purposes during the period beginning on the date of the issue of the warrants until December 31, 2013. Due to the anti-dilution provision of the warrants, the fair value of the outstanding warrants was classified within current liabilities on the consolidated balance sheets, and any changes in fair value were recognized as a reduction of revenue prior to the achievement of the performance milestones and as a component of other expense, net after both milestones were met, in its consolidated statements of comprehensive loss. During fiscal 2014 the Company performed the final remeasurement of the warrants prior to its exercise on December 17, 2013 and recorded an expense of $1.6 million , which was included in other expense, net. The Company determined the fair value of warrants on the issuance date and subsequent reporting dates using the Black-Scholes pricing model utilizing the assumptions noted below. The expected term of the warrants was based on the remaining contractual expiration period. The expected stock price volatility for the Company’s stock was determined by examining the historical volatilities of a group of its industry peers as it did not have any trading history of its common stock. The risk-free interest rate was calculated using the average of the published interest rates for U.S. Treasury zero-coupon issues with maturities that approximate the expected term. The dividend yield assumption was zero, as the Company does not have any history of, nor plans for, dividend payments. The following assumptions were used to estimate the fair value of the common stock warrants: Year Ended July 31, 2014 Expected volatility 34.9 – 37.0% Risk-free rate 0.07 – 0.11% Dividend yield —% Expected term (in years) 0.28 – 0.41 Fair value of common stock $4.11 – $7.38 No customer common stock warrants were issued or valued during the years ended July 31, 2016 and 2015.

The Company records a valuation allowance to reduce the amount of deferred tax assets to the amount that is more likely than not to be realized. Realization of deferred tax assets is dependent upon the generation of future taxable income, if any, the timing and amount of which are uncertain. Accordingly, the U.S. net deferred tax assets have been fully offset by a valuation allowance. A valuation allowance has not been recorded on certain foreign deferred net tax assets because these assets are expected to be realized on a more likely than not basis. The valuation allowance increased by $11.5 million and $23.1 million , respectively, during the years ended July 31, 2016 and 2015 . As of July 31, 2016 and 2015 , the Company had net operating loss carryforwards for federal income tax purposes of $224.1 million and $193.3 million , respectively, which expire in the years 2024 through 2035. As of July 31, 2016 and 2015 , the Company had net operating loss carryforwards for California state income tax purposes of $80.4 million and $162.5 million , respectively, which expire in the years 2016 through 2035 . We had elected the three-factor apportionment formula pursuant to the Multistate Tax Compact, or MTC, in determining the state net operating loss carryforwards for certain years. In December 2015, the California Supreme Court overturned the California Appellate court decision on The Gillette Company et al. v. California Franchise Tax Board. The court held that the taxpayers couldn’t elect an evenly weighted, three-factor apportionment formula pursuant to the MTC. As a result of the California Supreme Court decision, we reduced our deferred tax assets and offsetting valuation allowance related to the California NOL calculated in earlier years pursuant to the MTC election. As of July 31, 2016 and 2015 , the Company had R&D credit carryforwards for federal income tax purposes of $5.0 million and $3.1 million respectively, which expire in the years 2024 through 2035 . As of July 31, 2016 and 2015 , the Company had R&D credit carryforwards for California income tax purposes of $4.2 million and $2.9 million respectively, which have no expiration date. The Code, as amended, imposes restrictions on the utilization of net operating losses in the event of an “ownership change” of a corporation. Accordingly, a company’s ability to use net operating losses may be limited as prescribed under Internal Revenue Code Section 382 (“IRC Section 382”). Utilization of the federal and state net operating losses may be subject to substantial annual limitation due to the ownership change limitations provided by the IRC Section 382 and similar state provisions. Based on an analysis under Section 382 of the Internal Revenue Code, the Company experienced an ownership change in 2005 which substantially limits the future use of NOLs and certain other pre-change tax attributes as of that date. The Company has excluded the NOLs and R&D credits that will expire as a result of the annual limitations in the deferred tax assets as of July 31, 2016 . To the extent that the Company does not utilize the carryforwards within the applicable statutory carryforward periods, either because of Section 382 limitations or the lack of sufficient taxable income, the carryforwards will expire unused. The Company intends to reinvest its foreign earnings indefinitely. Accordingly, no U.S. income taxes have been provided on approximately $4.0 million of undistributed earnings and other outside basis differences of foreign subsidiaries. As of July 31, 2016 , it is not practicable for the Company to determine the potential income tax impact of remitting these earnings. The Company and its subsidiaries file income tax returns in the U.S. and in various states, local, and foreign jurisdictions. The tax years generally remain subject to examination by federal and most state tax authorities due to the ability to adjust net operating losses and credits. In significant foreign jurisdictions, the tax years generally remain subject to examination by their respective tax authorities. The Company is currently being audited by the India taxing authorities related to transfer pricing. Management has recorded a long-term tax liability for uncertain tax positions, including accrued interest and penalties. Uncertain Income Tax Positions The Company accounts for uncertainty in income taxes by determining whether it is more likely than not that a tax position will be sustained upon examination by the appropriate taxing authorities before any part of the benefit can be recorded in the consolidated financial statements. The following table summarizes the activity related to the Company’s unrecognized tax benefits: July 31, 2016 2015 (in thousands) Balance at beginning of year $ 1,805 $ 1,273 Increase related to prior year tax positions 202 194 Decrease related to prior year tax positions (13 ) (20 ) Increase related to current year tax positions 605 358 Decrease related to lapse of statute of limitations (48 ) — Balance at end of year $ 2,551 $ 1,805 If the gross unrecognized tax benefits at July 31, 2016 were recognized, $0.2 million of the recognition would affect the effective income tax rate. The Company is unable to make a reasonably reliable estimate as to when cash settlement with a taxing authority may occur. It is reasonably possible that the total amount of unrecognized tax benefits will increase or decrease in the next 12 months. The Company also recognizes interest and penalties accrued in relation to unrecognized tax benefits as a tax expense. For the years ended July 31, 2016 , 2015 and 2014 , the Company recorded charges to tax expense of $33,000 , $36,000 and $39,000 for interest and penalties, respectively. As of July 31, 2016 and 2015 , the Company had $0.4 million and $0.5 million of accrued interest and penalties, which are included in non-current income tax liabilities in the consolidated balance sheets.

Debt Disclosure [Abstract]
Long-term Debt	Long-term Debt In May 2012, we entered into a Loan and Security Agreement with Silicon Valley Bank (“SVB”), which was amended and restated in November 2014 and further amended on March 2, 2016 and May 23, 2016 (the “Loan Agreement”). As amended, the Loan Agreement provides us with the ability to borrow up to $25.0 million through a revolving line of credit, $ 7.5 million of which can be advanced at any time during the draw period and $ 17.5 million of which is subject to an accounts receivable borrowing base. We can draw upon the revolving line of credit through October 31, 2019, when all outstanding principal and accrued and unpaid interest becomes due and payable, and the revolving loans bear interest at a rate equal to the Prime Rate (as defined in the Loan Agreement the “Prime Rate”) plus 0.5% per annum (equal to 4.0% at July 31, 2016 ). Outstanding revolving loans subject to the accounts receivable borrowing base are limited to the lesser of (a) $ 17.5 million or (b) 80% of the balance of certain eligible customer accounts receivable plus the greater of $6.0 million million or 30% of eligible foreign accounts receivable. As of July 31, 2016 , we had not drawn on the revolving line of credit. Pursuant to the March 2, 2016 amendment, we also procured a supplemental term loan of $ 2.65 million , which refinanced, replaced and superseded our pre-existing term loan and equipment term loan in their entirety, and paid off the $ 156,250 end-of-term payment on the outstanding portion of the term loan. We will repay the outstanding principal of the supplemental term loan in monthly installments, plus interest at a rate equal to the Prime Rate plus 0.25% per annum (equal to 3.75% at July 31, 2016 ), with the last payment due in March 2018. So long as we are not in default, we are permitted to prepay the supplemental term loan in full without premium or penalty. The Loan Agreement contains customary affirmative covenants and certain financial and negative covenants, including restrictions on disposing of assets, entering into change of control transactions, mergers or acquisitions, incurring additional indebtedness, granting liens on our assets and paying dividends. After the March 2, 2016 amendment, we are required to maintain a minimum adjusted quick ratio of 1.75 :1 and a minimum total revenue of $35 million for the six months ended January 31, 2016, $54 million for the nine months ending April 30, 2016 and $74.75 million for the twelve months ending July 31, 2016 . For fiscal quarters after July 31, 2016 , the minimum total revenue we are required to maintain will be based on our annual plan for the next fiscal year using criteria consistent with the covenant for the twelve months ending July 31, 2016 (as approved by our board of directors). The minimum total revenue requirement for all future periods ending after July 31, 2016 will be subject to further adjustment by SVB. Stemming from non-compliance with a loan covenant at April 30, 2016, on May 23, 2016 we received a waiver of this requirement from SVB and amended the Loan Agreement to modify certain financial covenants. As of July 31, 2016 and 2015 , we were in compliance with all loan covenants. We have pledged substantially all of our assets, other than our intellectual property, as collateral under the Loan Agreement. The Loan Agreement contains customary events of default that include, among others, payment defaults, covenant defaults, bankruptcy defaults, cross-defaults to certain other obligations, judgment defaults and inaccuracy of representations and warranties. Upon the occurrence of an event of default, SVB may elect to declare all amounts outstanding under the Loan and Security Agreement to be immediately due and payable and terminate all commitments to extend further credit. If the Company is unable to repay all amounts outstanding, SVB can proceed against the collateral granted to them to secure such indebtedness. In addition, the occurrence of an event of default will increase the applicable rate of interest by three percentage points for the applicable unpaid loan(s). As of July 31, 2016 and 2015, the Company was in compliance with all loan covenants. The Company’s outstanding loan balances as of July 31, 2016 and July 31, 2015 are summarized as follows: July 31, Outstanding Loan Balances 2016 2015 (in thousands) Silicon Valley Bank term loan $ — $ 2,934 Silicon Valley Bank equipment loan — 958 Silicon Valley Bank supplemental loan 2,207 — Total principal amount 2,207 3,892 Less: Unamortized discount (7 ) (26 ) Total debt 2,200 3,866 Less: current portion (1,318 ) (2,079 ) Non-current debt, excluding current portion $ 882 $ 1,787 The future principal maturities of debt as of July 31, 2016 are as follows: (in thousands) 2017 $ 1,324 2018 883 Total $ 2,207 In connection with the original Loan Agreement, the Company issued SVB warrants (“SVB warrants”) to purchase 3,495 shares of common stock during the year ended July 31, 2015 . On May 13, 2015, 65,788 warrant shares issued in earlier periods were net exercised on a cashless basis resulting in issuance of 57,082 common shares. Warrants to purchase 3,495 shares have an exercise price of $13.68 and expire in November 2024. The fair value of the SVB warrants was determined using the Black-Scholes option valuation model. As of July 31, 2016 and 2015 , 3,495 of these warrants to purchase shares of common stock remained outstanding and exercisable. There were no warrants issued to SVB during the year ended July 31, 2016.

Future minimum lease payments under non-cancelable operating leases as of July 31, 2016 are as follows: (in thousands) 2017 $ 2,131 2018 1,851 2019 1,655 Total future minimum operating lease payments $ 5,637 Letters of Credit As of July 31, 2016 , the Company had a total of $0.5 million in letters of credit outstanding related to its leased office space in San Jose, California. The letters of credit are collateralized by substantially all of the Company’s assets, excluding its intellectual property. These letters of credit renew annually and mature at various dates through June 30, 2019. Legal Matters and Contingencies The Company makes a provision for a liability relating to legal matters and loss contingencies when it is both probable that a liability has been or will be incurred and the amount of the loss can be reasonably estimated. Beginning on March 17, 2016, four purported shareholder class action complaints were filed in the Superior Court of the State of California, County of San Mateo, against the Company, the Company’s directors, certain of the Company’s executive officers, the underwriters of the Company’s IPO and other defendants. The lawsuits were brought by purported stockholders of the Company seeking to represent a class consisting of all purchasers of the Company’s common stock pursuant or traceable to the Registration Statement and Prospectus issued in connection with the Company’s IPO. These complaints allege claims under federal securities laws that such Registration Statement and Prospectus contained false and/or misleading statements or omissions. These complaints seek unspecified compensatory damages and other relief. The Company believes that the claims are without merit and intends to defend these lawsuits vigorously. From time to time, the Company may become a party to other litigation and subject to claims incident to the ordinary course of business, including intellectual property claims, labor and employment claims, and threatened claims, breach of contract claims, tax, and other matters. The Company is not presently a party to any other legal proceedings that, if determined adversely to us, would individually or taken together have a material adverse effect on our business, operating results, financial condition or cash flows. Indemnification Arrangements In the ordinary course of business, the Company enters into contractual arrangements under which it agrees to provide indemnification of varying scope and terms to customers, business partners and other parties with respect to certain matters, including, losses arising out of the breach of such agreements, intellectual property infringement claims made by third parties, and other liabilities with respect to the Company’s products and services and its business. In these circumstances, payment may be conditional on the other party making a claim pursuant to the procedures specified in the particular contract. The Company includes service level commitments to its cloud customers warranting certain levels of uptime reliability and performance and permitting those customers to receive credits in the event that it fails to meet those levels. To date, the Company has not incurred any material costs as a result of these commitments and the Company expects the time between any potential claims and issuance of the credits to be short. As a result, the Company has not accrued any liabilities related to these commitments in the Company’s consolidated financial statements. In addition, the Company has indemnification agreements with its directors and certain of its executive officers that require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers.

Stock Incentive Plan	Stock Incentive Plan 2005 Stock Incentive Plan In 2005, the Company adopted the 2005 Stock Incentive Plan (the “2005 Plan”), which was amended in April 2014. The 2005 Plan was terminated in connection with the IPO with respect to the granting of future awards, and accordingly, no shares are available for future issuance under this plan. All shares that were reserved but not issued under the 2005 Plan as of immediately prior to its termination became available for issuance under the 2015 Equity Incentive Plan (the “2015 Plan”) upon its adoption. Shares reserved for issuance pursuant to awards under the 2005 Plan that expire or terminate without having been exercised subsequent to the IPO or are forfeited to or repurchased by the Company subsequent to the IPO became available for issuance under the 2015 Plan, subject to the limits set forth in the 2015 Plan. 2015 Equity Incentive Plan In April 2015, the Board adopted and the Company’s stockholders approved the 2015 Equity Incentive Plan (the “2015 Plan”), which became effective upon the effectiveness of the registration statement in connection with our IPO. As of such date, an aggregate of 2,700,000 shares of common stock were reserved for issuance under the 2015 Plan, plus (a) those shares reserved but unissued under our 2005 Plan as of immediately prior to the termination of the 2005 Plan and (b) shares subject to options, restricted stock units, or similar awards granted under the 2005 Plan that, after the effectiveness of the registration statement, expire or otherwise terminate without having been exercised or issued in full and shares issued pursuant to awards granted under the 2005 Plan that, after the effectiveness of the registration statement, are forfeited to or repurchased by the Company (provided that the maximum number of shares that may be added to the 2015 Plan pursuant to (a) and (b) is 4,515,212 shares). Additionally, the 2015 Plan provides that the number of shares reserved and available for issuance will increase annually on the first day of each fiscal year beginning with the 2016 fiscal year equal to the least of (i) 3,100,000 shares of Common Stock, (ii) 4% of the outstanding shares of Common Stock on the last day of immediately preceding fiscal year, or (iii) an amount determined by the board of directors. The 2015 Plan provides for the grant of incentive stock options, within the meaning of Section 422 of the Code, to the Company’s employees and any parent and subsidiary corporations’ employees, and for the grant of nonstatutory stock options, restricted stock, restricted stock units, stock appreciation rights, performance units and performance shares to the Company’s employees, directors and consultants and its parent and subsidiary corporations’ employees and consultants. As of July 31, 2016 , an aggregate of 4,349,738 common shares were reserved under the 2015 Plan, of which 430,729 shares remained available for issuance. 2015 Employee Stock Purchase Plan The Company’s Board of Directors adopted and the Company’s stockholders approved the 2015 Employee Stock Purchase Plan (the “ESPP”) with the first offering period under the ESPP beginning on the effectiveness of the registration statement in connection with our IPO. As of such date, an aggregate of 775,000 shares of common stock were reserved and are available for issuance under the ESPP. Additionally, the ESPP provides that the number of shares reserved and available for issuance will increase annually on the first day of each fiscal year beginning with the 2016 fiscal year equal to the least of (i) 775,000 shares of Common Stock, (ii) 1% of the outstanding shares of Common Stock on the last day of immediately preceding fiscal year, or (iii) an amount determined by the ESPP administrator. The ESPP allows eligible employees to purchase shares of common stock at a discount through payroll deductions of up to 15% of their eligible compensation, at 85% of the fair market value, as defined in the ESPP, on the first day of the offering period or the last day of the purchase period, whichever is lower, and subject to any plan limitations. The ESPP provides for consecutive six -month offering periods, starting on the first trading day on or after June 15 and December 15 of each year. The first offering period began on the first trading day on the effective date of the registration statement and ended on December 15, 2015.

The expected term of the stock-based awards is based on the average period the stock-based awards are expected to remain outstanding calculated as the midpoint of the stock-based awards’ vesting terms and contractual expiration periods, as the Company does not have sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior. The expected stock price volatility for the Company’s common stock was determined by examining the historical volatilities of a group of its industry peers as it does not have sufficient trading history of the Company’s common stock. The risk-free interest rate was calculated using the average of the published interest rates for United States Treasury zero-coupon issues with maturities that approximate the expected term. The dividend yield assumption is zero as the Company does not have any history of, nor plans to make, dividend payments. Forfeitures were estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differed from those estimates. Forfeitures were estimated based on historical experience. The fair value of the common stock was historically determined by the Company’s board of directors given the absence of a public trading market prior to its IPO. The board of directors determined the fair value of the common stock at the time of the stock-based award grant by considering a number of objective and subjective factors, including valuations of comparable companies, operating and financial performance, lack of liquidity of capital stock and general and industry-specific economic outlooks, amongst other factors. Since the Company’s IPO, the Company has used the market closing price of the common stock as reported on the NASDAQ Global Select Market. The following assumptions were used to estimate the fair value of options granted: Year Ended July 31, 2016 2015 2014 Expected term (in years) 5.5 – 6.2 5.8 – 6.4 5.5 – 6.9 Risk-free interest rate 1.3 –1.9 1.5 –1.9 1.7 – 2.3 Expected volatility 43 – 45 39 – 44 48 – 50 Dividend yield — % — % — % Fair value of common stock $7.41 – $12.96 $10.41 – $17.56 $4.11 – $9.12 The following assumptions were used to estimate the fair value of ESPP shares: Year Ended July 31, 2016 2015 Expected term (in years) 0.5 0.7 Risk-free interest rate 0.4% – 0.5% 0.1 % Expected volatility 36% – 40% 30 % Dividend yield — % — % Fair value of common stock $8.27 – $12.81 $ 17.00 Employee Stock Purchase Plan As of July 31, 2016 , the remaining unamortized expense related to the Company’s 2015 ESPP Plan was $0.4 million , which will be recognized over a weighted-average remaining period of 0.4 years. Series G-1 Stock Stock-based compensation expense for the year ended July 31, 2016 and 2015 included $0.2 million and $0.6 million , respectively, of amortization expense for Series G-1 convertible preferred stock (which have since been converted to common stock) issued to former employees of InsightsOne. The awards are subject to vesting on a monthly basis over certain vesting periods. As of July 31, 2016 , the remaining unamortized expense related to these shares was less than $0.1 million , which will be recognized over a weighted-average remaining period of 0.4 years. Restricted Stock Units A summary of RSUs under the Company’s equity plans and related information was as follows: RSUs Outstanding Aggregate Intrinsic Value (In thousands) Number of Shares Weighted- Average Grant- Date Fair Value Weighted- Average Remaining Contractual Life (Years) Balances at July 31, 2013 66,775 $ 1.05 Granted 20,343 7.48 Released (70,655 ) 1.43 Forfeited (657 ) 7.38 Balances at July 31, 2014 15,806 7.38 Granted 266,257 13.92 Released — — Forfeited (2,917 ) 7.38 Balances at July 31, 2015 279,146 13.68 3.58 $ 2,247 Granted 2,564,275 8.93 Released (156,708 ) 10.70 Forfeited (261,819 ) 8.65 Balances at July 31, 2016 2,424,894 $ 9.39 3.27 $ 30,166 The Company grants RSUs as part of total stock compensation and such grants may have time-based vesting, performance-based vesting or a combination of the two. The fair value of time-based RSUs is determined using the closing market price on the date of grant. As of July 31, 2016 , the remaining unamortized expense related to all RSUs was $7.9 million which will be recognized over a weighted-average remaining period of 3.3 years . There were RSUs granted in connection with the acquisition of InsightsOne in fiscal 2014. Such RSUs are subject to a time-based vesting condition and a performance-based vesting condition, both of which must be satisfied before these RSUs are vested and settled for shares of common stock. The time-based vesting condition is three years and the performance-based vesting condition was satisfied upon the completion of the Company’s initial public offering in April 2015. The remaining expense is de minimus.

Earnings Per Share [Abstract]
Net Loss Per Share	Net Loss Per Share The Company computes net loss per share of common stock in conformity with the two-class method required for participating securities. The Company considers all series of the convertible preferred stock to be participating securities as the holders of the preferred stock are entitled to receive a non-cumulative dividend on a pari passu basis in the event that a dividend is paid on the common stock. The holders of the convertible preferred stock do not have a contractual obligation to share in the Company’s losses. As such, the Company’s net losses for the years ended July 31, 2016 , 2015 and 2014 were not allocated to these participating securities. Basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential shares of common stock, including common stock issuable upon conversion of the convertible preferred stock, outstanding stock-based awards, and outstanding warrants, to the extent dilutive. Basic and diluted net loss per share was the same for each period presented as the inclusion of all potential common stock outstanding would have been anti-dilutive. The following table presents the calculation of basic and diluted net loss per share for the periods presented: Year Ended July 31, 2016 2015 2014 (in thousands except per share amounts) Numerator: Net loss $ (41,512 ) $ (50,353 ) $ (60,793 ) Denominator: Weighted-average shares used to compute net loss per share, basic and diluted 29,769 10,651 3,413 Net loss per share, basic and diluted $ (1.39 ) $ (4.73 ) $ (17.81 ) Since the Company was in a loss position for all periods presented, basic net loss per share is the same as diluted net loss per share 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: Year Ended July 31, 2016 2015 2014 (in thousands) Shares subject to outstanding common stock options 4,639 4,275 4,009 Convertible preferred stock (on an as if converted basis) — — 19,811 Restricted stock units 2,425 279 16 Shares subject to employee stock purchase plan 207 206 — Restricted common stock 3 45 — Shares subject to common stock warrants 3 3 66 Total 7,277 4,808 23,902

Accounting Policies [Abstract]
Initial Public Offering	Initial Public Offering On April 29, 2015 the Company completed its initial public offering (the “IPO”) in which it sold 5,115,000 shares of common stock to the public at $17.00 per share. The total gross proceeds from the offering were approximately $87.0 million . After deducting underwriting discounts and commissions and offering expenses payable by the Company, the aggregate net proceeds received totaled approximately $76.9 million . The sale of common stock in the IPO triggered the weighted average anti-dilution provisions of the Company’s amended and restated certificate of incorporation then in effect. At the IPO price of $17.00 per share, the per share conversion rate for the Company’s Series H convertible preferred stock into common stock was approximately 1: 1.0365 . In connection with the completion of the IPO, and giving effect to the anti-dilution adjustment relating to the Company’s Series H convertible preferred stock, all shares of the Company’s convertible preferred stock outstanding automatically converted into 19,818,172 shares of the Company’s common stock.
Reverse Stock Split	Reverse Stock Split On April 7, 2015, the Company effected a 1-for-7.6 reverse stock split of its common stock and convertible preferred stock, as approved by its Board of Directors (the “Board”) and stockholders. All information throughout these consolidated financial statements and notes to the consolidated financial statements relating to the number of shares, price per share and per share amounts have been adjusted to give effect to the 1-for-7.6 reverse stock split. All fractional shares were settled in cash.
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”). The accompanying consolidated financial statements include the accounts of Apigee Corporation and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated upon consolidation.
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 at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period covered by the consolidated financial statements and accompanying notes. In particular, the Company makes estimates with respect to the fair value of multiple elements in revenue recognition, uncollectible accounts receivable, assets acquired and liabilities assumed in a business combination, valuation of long-lived assets, stock-based compensation, income taxes and other contingencies. Actual results could differ from those estimates and such differences could be material to the financial statements and affect the results of operations reported in future periods.
Foreign Currency Transactions	Foreign Currency Transactions The functional currency of the Company’s foreign subsidiaries is the U.S. dollar. Accordingly, monetary balance sheet accounts are remeasured using the current exchange rate in effect at the balance sheet date and non-monetary items are remeasured at the historical exchange rate. Expenses are remeasured at the average exchange rates for the period. The resulting gains and losses are included in other expense, net and were not material for the years ended July 31, 2016 , 2015 and 2014 .
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid instruments with original or remaining maturities of 90 days or less at the date of purchase to be cash equivalents. Cash and cash equivalents are stated at cost, which approximates fair value. As of July 31, 2016 and 2015 , $66.0 million and $86.4 million , respectively, of cash and cash equivalents were invested in money market funds.
Concentration of Risk and Significant Customers	Concentration of Risk and Significant Customers Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company maintains the majority of its cash and money market accounts at one financial institution that management believes is a high-credit, high-quality financial institution and accordingly, subject to minimal credit risk. Deposits held with these financial institutions may be in excess the amount of insured limits provided on such deposits, if any. The Company’s accounts receivable are subject to credit risks. The accounts receivable are unsecured and are derived from customers around the world in a variety of industries.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts The Company’s accounts receivable are recorded at invoiced amounts, net of the Company’s estimated allowances for doubtful accounts. The allowance for doubtful accounts is estimated based on an assessment of the Company’s ability to collect on customer accounts receivable. The Company performs ongoing credit evaluations of its customers and regularly reviews the allowance by considering certain factors such as historical experience, industry data, credit quality, age of accounts receivable balances and current economic conditions that may affect a customer’s ability to pay. In cases where the Company is aware of circumstances that may impair a specific customer’s ability to meet their financial obligations, the Company records a specific allowance against amounts due from the customer and thereby reduces the net recognized receivable to the amount the Company reasonably believes will be collected. There is judgment involved with estimating the Company’s allowance for doubtful accounts and if the financial condition of its customers were to deteriorate, resulting in their inability to make the required payments, the Company may be required to record additional allowances or charges against revenue. The Company writes off accounts receivable against the allowance when it determines a balance is uncollectible and no longer actively pursues collection of the receivable. The Company’s accounts receivable are not collateralized by any security.
Property and Equipment, Net	Property and Equipment, Net Property and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets generally ranging from three to five years . Leasehold improvements are amortized over the shorter of the estimated useful life or the remaining lease term. When assets are retired or disposed of, the cost and accumulated depreciation are removed from the accounts, and any resulting gains or losses are included in the consolidated statements of comprehensive loss. Maintenance and repairs that do not improve or extend the lives of the respective assets are expensed in the period incurred.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Assets and liabilities recorded at fair value in the financial statements are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels which are directly related to the amount of subjectivity associated with the inputs to the valuation of these assets or liabilities are as follows: Level 1—Observable inputs, such as quoted prices in active markets for identical assets or liabilities. Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company has certain financial assets and liabilities that are measured at fair value on a recurring basis. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and considers factors specific to the asset or liability. The Company’s cash equivalents include highly liquid money market funds and are classified within the Level 1 of the fair value hierarchy. Level 3 liabilities that are measured at fair value on a recurring basis consist solely of the Company’s common stock warrant liability. The fair values of the outstanding common stock warrants are measured using the Black-Scholes option-pricing model. Inputs used to determine estimated fair value include the estimated fair value of the underlying stock at the valuation measurement date, the remaining contractual term of the warrants, risk-free interest rates, expected dividends, and the expected volatility of the underlying stock. Generally, increases (decreases) in the fair value of the underlying stock and estimated term would have a directionally similar impact to the fair value measurement. The carrying amounts of certain of the Company’s financial instruments including cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair value due to their short-term maturities. Based on borrowing rates currently available to the Company for financing obligations with similar terms and considering the Company’s credit risks, the carrying value of the Company’s long-term debt approximates fair value.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired in a business combination. Goodwill is not amortized, but is tested for impairment at least annually or more frequently if events or changes in circumstances indicate that the asset may be impaired. The Company’s impairment tests are based on a single operating segment and reporting unit structure. If the Company determines that it is more likely than not that the fair value of the Company’s reporting unit is less than the carrying value, it will conduct a two-step test for impairment of goodwill. The first step involves comparing the fair value of the Company’s reporting unit to its carrying value, including goodwill. If the carrying value of the reporting unit exceeds its fair value, the second step of the test is performed by comparing the carrying value of the goodwill in the reporting unit to its implied fair value. An impairment charge is recognized for the excess of the carrying value of goodwill over its implied fair value. The Company’s annual goodwill impairment test resulted in no impairment charges during the years ended July 31, 2016 , 2015 or 2014 . Intangible assets acquired as part of a business combination, consisting primarily of developed technology, customer relationships and backlog are capitalized at their acquisition-date fair value and amortized using the straight-line method over their estimated useful life.
Impairment of Long-lived Assets	Impairment of Long-lived Assets Long-lived assets, such as property, plant, and equipment, and purchased intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of these assets is measured by a comparison of the future undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value.
Business Combinations	Business Combinations The Company recognizes assets acquired, liabilities assumed and contingent consideration at their fair value on the acquisition date. The Company’s estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company’s consolidated statements of comprehensive loss. In addition, uncertainties in income tax and tax related valuation allowances assumed in connection with a business combination are initially estimated as of the acquisition date. The Company continues to gather information and evaluates these items and records any adjustments to the Company’s preliminary estimates to goodwill when the Company is within the measurement period. Subsequent to the measurement period, changes to these income tax uncertainties and tax related valuation allowances will affect the Company’s provision for income taxes in the Company’s consolidated statements of comprehensive loss.
Capitalized Software Development Costs	Capitalized Software Development Costs Software development costs are expensed as incurred until the establishment of technological feasibility, at which time those costs are capitalized until the product is available for general release to customers and amortized over the estimated life of the product. Technological feasibility is established upon completion of a working model. To date, costs incurred subsequent to the establishment of technological feasibility have not been significant, and all software development costs have been charged to research and development expense in the accompanying consolidated statements of comprehensive loss.
Revenue Recognition	Revenue Recognition The Company generates revenue from the sale of its software solutions to customers through perpetual licenses and time-based licenses for its on premises solutions, and subscription arrangements for its cloud service. The Company also generates revenue from the sale of post-contract software support for on premises licenses including when and if available updates, and professional services such as consulting and training services. The Company recognizes revenue when all of the following conditions are met: • persuasive evidence of an arrangement exists; • delivery has occurred or services have been provided; • sales price is fixed or determinable; and • collection of the related receivable is probable. Signed agreements, including by electronic acceptance, are used as evidence of an arrangement. For the Company’s on premises solution, delivery is considered to occur when it provides the customer the ability to download the software. For the Company’s cloud service solution, delivery is considered to occur when a subscription service is provisioned and made available to a customer. The Company assesses whether a fee is fixed or determinable at the outset of the arrangement, primarily based on the payment terms associated with the sale. The Company assesses collectability of the fee based on a number of factors such as collection history and creditworthiness of the customer. If the Company determines that collectability is not probable, revenue is deferred until collectability becomes probable, generally upon receipt of payment from the customer. The Company typically enters into multiple-element arrangements with its customers in which a customer may purchase a combination of its software (offered on premises with software support or as a cloud service) solution, and professional services. The software support and professional services are not considered essential to the functionality of the software. All of these elements are considered separate units of accounting. Typically, the Company’s agreements do not include rights for customers to cancel or terminate arrangements or to return software to obtain refunds. The Company presents revenue on a net basis, and therefore, all sales taxes are excluded from revenue in the consolidated statements of comprehensive loss. Travel and other reimbursable costs are recorded in revenue. License License revenue is comprised of revenue generated from licenses of the Company’s on premises perpetual and time-based software solutions. The majority of the Company’s perpetual software license arrangements include a combination of the Company’s software downloaded on the customer’s hardware, software support, or professional services. For software elements, under the software revenue recognition guidance, the residual method is used to recognize revenue when a multiple-element arrangement includes one or more elements to be delivered at a future date and vendor-specific objective evidence (“VSOE”) of fair value of all undelivered element exists. VSOE is defined as the price charged when the same element is sold separately or for an element not yet being sold separately, the price established by management having relevant authority. In the majority of the Company’s software arrangements, the only element that remains undelivered at the time of delivery of the software product is software support or services. The Company has established VSOE for consulting days, training and software support, except for software support bundled with time-based licenses, based on a substantial majority of separate stand-alone sales of these elements, which have been priced within a reasonably narrow range. As a result, for multiple element arrangements that include perpetual licenses, revenue is allocated to the undelivered elements based on VSOE for support or consulting days and training. Using the residual method, the difference between the total arrangement fee and amount deferred for the undelivered elements is recognized upon delivery of the perpetual license if all other revenue recognition criteria are met. The Company does not have VSOE for software support bundled with time-based licenses. Therefore, revenue from time-based licenses to the Company’s on-premises solution is generally recognized ratably over the contractual term for all periods presented. Subscription and Support Subscription and support revenue includes the revenue derived from customer subscriptions to the Company’s cloud service and software support for its on premises software licenses. Cloud service arrangements generally include the Company’s cloud service solution offered on a subscription basis and professional services. The term of the arrangement allows for the customer to access the Company’s software for a specified period of time, generally one to three years . In cloud service subscription arrangements, the customer is not allowed to take possession of the Company’s software. Revenue from subscriptions to the Company’s cloud service is generally recognized ratably over the contractual term for all periods presented. When cloud service subscription arrangements involve multiple elements that qualify as separate units of accounting (i.e., the delivered items have stand-alone value), the Company allocates arrangement consideration based on the relative selling price method using the following selling price hierarchy: (1) VSOE if available; (2) third-party evidence (“TPE”), if VSOE is not available; and (3) best estimate of selling price (“BESP”) if neither VSOE nor TPE is available. The Company has not historically priced its cloud service solution within a narrow range and, therefore, cannot establish VSOE. The Company also believes that TPE is not readily available for its cloud service as pricing is not readily accessible and there is no comparable product offering in the market. As a result, the Company uses BESP in order to allocate the selling price to cloud deliverables. The Company determines BESP considering multiple factors including, but not limited to, the price it charges for similar offerings, market conditions, competitive landscape, and pricing practices. For cloud offerings that include consulting days and training, the Company uses BESP for cloud deliverables and VSOE for consulting days and training to allocate revenue into separate units of accounting. Revenue for the cloud service is generally recognized over the subscription period when all other revenue recognition criteria are met. Consulting days and training are recognized as the services are performed, as discussed below. Revenue from software support for the Company’s on-premises perpetual and time-based software licenses is generally recognized ratably over the contractual term, which is typically one to three years . Software support is bundled with time-based licenses and the Company uses a consistent systematic and rational method to allocate between time-based license and support revenue for financial statement presentation purposes only. Professional Services and Other Generally, the Company’s professional service arrangements are short-term in nature and not considered essential to the functionality of the Company’s software. Professional services are generally offered as consulting days, time and material and fixed-fee arrangements. Consulting days are recognized as revenue as the services are performed on an hourly basis or upon expiration of the service period. Time and material services are recognized as revenue as services are rendered based on inputs to the project, such as billable hours incurred. For fixed-fee professional service arrangements, the Company recognizes revenue under the proportional performance method of accounting and estimates the proportional performance on a monthly basis, utilizing hours incurred to date as a percentage of the total estimated hours to complete the project. In cases where the Company has on premises perpetual or time-based license and professional services arrangements requiring significant customization and implementation that are considered essential to the functionality of the software, the arrangement is accounted for using contract accounting until the essential services are complete. If the Company can make reliable estimates of total project costs and the extent of progress toward completion, it applies the percentage-of-completion method in recognizing the arrangement fee.
Deferred Revenue	Deferred Revenue Deferred revenue primarily consists of billings or payments received in advance of revenue recognition from the Company’s product offerings described above and is recognized as the revenue recognition criteria are met. Deferred revenue that will be recognized during the following 12 months is recorded as a current liability and the remaining portion is recorded as non-current.
Deferred Cost of Revenue	Deferred Cost of Revenue Deferred cost of revenue primarily consists of direct costs for professional services from multiple-element arrangements either accounted for using the completed contract method or subject to acceptance. The direct costs are being recognized in proportion to the related revenue.
Product Warranties	Product Warranties The Company generally provides a warranty for its software products and services to its customers for periods ranging from one to six months . The Company’s software products are generally warranted to be free of defects in materials and workmanship under normal use and the products are also generally warranted to substantially perform as described in published documentation. The Company’s services are generally warranted to be performed in a professional manner and to materially conform to the specifications set forth in the related customer contract. In the event there is a failure of such warranties, the Company generally will correct the problem or provide a reasonable workaround or replacement product. If the Company cannot correct the problem or provide a workaround or replacement product, then the customer’s remedy is generally limited to refund of the fees paid for the nonconforming product or services. To date, the warranty expenses have been insignificant.
Sales Commissions	Sales Commissions Sales commissions are recorded as a component of sales and marketing expenses and consist of the variable compensation paid to the Company’s sales force. Sales commissions are earned and recorded at the time that a customer has entered into a binding license, subscription or services agreement.
Research and Development	Research and Development Research and development costs are expensed as incurred, except for certain internal-use software development costs, which may be capitalized as noted above.
Advertising	Advertising The Company expenses advertising costs as incurred as a component of sales and marketing expenses.
Stock-based Compensation	Stock-based Compensation The Company recognizes compensation expense for all stock-based awards, including stock options, ESPP and restricted stock units (“RSUs”), based on the estimated fair value of the award on the grant date in the consolidated statements of comprehensive loss over the related vesting periods. The expense recorded is based on awards ultimately expected to vest and therefore is reduced by estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company calculates the fair value of awards using the Black-Scholes option pricing model and records expense using the straight-line attribution approach. The determination of the grant date fair value of awards is affected by a number of complex variables, which include the Company’s fair value of common stock, expected term of the options, expected volatility, risk-free interest rates and expected dividends. Prior to the Company's IPO, the Company engaged an outside expert to assist management with the valuation of the Company's common stock grants. The Company accounts for equity awards issued to non-employees, such as consultants, in accordance with the guidance relating to equity instruments that are issued to other than employees for acquiring, or in conjunction with selling, goods or services, using the Black-Scholes option pricing model to determine the fair value of such instruments. Awards granted to non-employees are remeasured over the vesting period, and the resulting value is recorded as an expense over the period the services are received.
Segments	Segments The Company operates its business as one operating segment. The Company’s chief operating decision maker is its Chief Executive Officer, who reviews financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance and allocating resources.
Taxes	Taxes Income Taxes The Company accounts for income taxes using the asset and liability approach. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company evaluates the realizability of its deferred income tax assets and assesses the need for a valuation allowance on an ongoing basis. In evaluating its deferred income tax assets, the Company considers all available positive and negative evidence related to the likelihood of realization of the deferred tax assets to determine, based on the weight of available evidence, whether it is more likely than not that some or all of the deferred tax assets will not be realized. The Company has recorded a full valuation allowance on its U.S. deferred tax assets as of July 31, 2016 because the realization of these tax benefits through future taxable income is not more likely than not as of July 31, 2016 . The valuation allowance will be maintained until sufficient positive evidence exists to support the reversal of the valuation allowance. The Company makes estimates and judgments about its future taxable income that are based on assumptions that are consistent with the plans and estimates. Should the actual amounts differ from the estimates, the amount of the valuation allowance could be materially impacted. The Company accounts for uncertain tax positions using a two-step approach for recognizing and measuring uncertain tax positions. Tax positions are evaluated for recognition by determining if the weight of available evidence indicates that it is probable that the position will be sustained on audit, including resolution of related appeals or litigation. Tax benefits are then measured as the largest amount which is more than 50% likely of being realized upon ultimate settlement. The Company considers many factors when evaluating and estimating tax positions and tax benefits, which may require periodic adjustments and which may not accurately anticipate actual outcomes. The Company recognized potential accrued interest and penalties related to unrecognized tax benefits in tax expense. Other Taxes The Company conducts operations in many tax jurisdictions throughout the U.S and around the world. In many of these jurisdictions, non-income based taxes such as property taxes, sales and use taxes, and value-added taxes are assessed on the Company’s operations in that particular location. While the Company strives to ensure compliance with these various non-income based tax filing requirements, there have been instances where potential non-compliance exposures have been identified. In accordance with GAAP, the Company makes a provision for these exposures when it is both probable that a liability has been incurred and the amount of the exposure can be reasonably estimated. The Company believes that, as of July 31, 2016 and 2015 , it has adequately provided for such contingencies. However, it is possible that the Company’s results of operations, cash flows, and financial position could be harmed if one or more non-compliance tax exposures are asserted by any of the jurisdictions where the Company conducts its operations.
Commitments and Contingencies	Commitments and Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when it is probable that a liability has been or will be incurred and the amount of the liability can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards Share-Based Payments with Performance Targets: In June 2014, the FASB issued Accounting Standards Update No. 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (ASU 2014-12). ASU 2014-12 requires that a performance target that affects vesting and could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in ASC 718, Compensation—Stock Compensation , as it relates to such awards. ASU 2014-12 is effective for the Company in its first quarter of fiscal 2017 with early adoption permitted using either of two methods: (1) prospective to all awards granted or modified after the effective date; or (2) retrospective to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter, with the cumulative effect of applying ASU 2014-12 as an adjustment to the opening retained earnings balance as of the beginning of the earliest annual period presented in the financial statements. The Company has elected to early adopt the new standard using the retrospective adoption method. The adoption of this standard did not have a material effect on its financial position. Balance Sheet Classification of Deferred Taxes: In November 2015, the FASB issued ASU 2015-17, “ Balance Sheet Classification of Deferred Taxes ”, which requires that all deferred tax assets and liabilities be classified as non-current on the balance sheet. The amendments in ASU 2015-17 are intended to simplify the presentation of deferred income taxes. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2016 and interim periods within those fiscal years. Early adoption is permitted. The Company early adopted the ASU in the fourth quarter of the year ended July 31, 2016. This guidance did not have a material impact on the Company’s consolidated financial statements.
