Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Applicable Accounting Guidance Any reference in these notes to applicable accounting guidance is meant to refer to the authoritative United States generally accepted accounting principles (“GAAP”) as found in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”). Basis of Presentation The interim financial data as of October 31, 2015 and for the three and nine months ended October 31, 2015 and 2014 are unaudited; however, in the opinion of the Company’s management, the interim data includes all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results for the interim periods presented. The condensed consolidated balance sheet presented as of January 31, 2015 has been derived from the audited consolidated financial statements as of that date. The unaudited condensed consolidated financial statements presented herein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Accordingly, they do not include all of the information and note disclosures required by GAAP for complete financial statements and should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Exa annual report on Form 10-K for the year ended January 31, 2015 filed with the Securities and Exchange Commission on March 24, 2015. Reclassification Certain prior year amounts have been reclassified to be consistent with current year classifications. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results could differ from management’s estimates if future events differ substantially from past experience, or other assumptions, which reasonable when made, do not turn out to be substantially accurate.

Earnings Per Share [Abstract]
Computation of Net (Loss) Income Per Share	3. Computation of Net (Loss) Income Per Share Net (loss) income per share has been computed using the weighted average number of shares of common stock outstanding during each period. Diluted amounts per share include the impact of the Company’s outstanding potential common shares, such as shares issuable upon exercise of in-the-money stock options or warrants, when dilutive. Potential common shares that are anti-dilutive are excluded from the calculation of diluted net (loss) income per common share. The following summarizes the calculation of basic and diluted net (loss) income per share: Three Months Ended October 31, Nine Months Ended October 31, 2015 2014 2015 2014 Numerator: Net (loss) income $ (433 ) $ 220 $ (3,516 ) $ (18,009 ) Denominator: Weighted average common shares, basic 14,610,479 13,822,400 14,484,563 13,701,380 Dilutive effect of: Options to purchase common and preferred stock — 898,619 — — Warrants to purchase common stock — 9,285 — — Restricted stock units — 19,521 — — Weighted average common shares, diluted 14,610,479 14,749,825 14,484,563 13,701,380 Basic net (loss) income per share $ (0.03 ) $ 0.02 $ (0.24 ) $ (1.31 ) Diluted net (loss) income per share $ (0.03 ) $ 0.02 $ (0.24 ) $ (1.31 ) The table below represents outstanding options, restricted stock unit awards and warrants that were excluded from the computation of diluted net (loss) income per share for the periods indicated because including them would have had an anti-dilutive effect. All of the Company’s outstanding stock options, unvested restricted stock units and warrants were anti-dilutive for the three months ended October 31, 2015 and for the nine months ended October 31, 2015 and 2014 due to the net loss incurred by the Company.

Deferred rent consists of the following: October 31, January 31, Leasehold improvement incentive $ 1,234 $ 308 Cumulative non-cash rent expense 853 761 Total deferred rent 2,087 1,069 Less: current portion included in accrued expenses (38 ) (597 ) Deferred rent, net of current portion $ 2,049 $ 472 As discussed in Note 9, the Company entered into an amendment to its corporate headquarter lease in Burlington, Massachusetts effective July 1, 2015. The amendment provided for a tenant improvement allowance of up to $1,681 to cover renovations being made to the Company’s leased space over the remainder of fiscal year 2016. As of October 31, 2015, the Company recorded $1,047 of the tenant improvement allowance as an increase to deferred rent for renovation costs incurred to date. Of these costs, the Company paid for approximately $493, and accordingly, recorded a receivable from the landlord for this amount which is included in other current assets in the accompanying consolidated balance sheet. The $554 balance of these costs was funded by the landlord and is recorded as construction-in-process within property and equipment, net in the accompanying consolidated balance sheet.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	7. Fair Value Measurements Financial instruments consist primarily of cash and cash equivalents, accounts receivable and capital lease obligations. As of October 31, 2015 and January 31, 2015, the carrying amounts of these instruments approximate their fair values. The estimated fair values have been determined from information obtained from market sources and management estimates. In determining the fair value of its financial assets and liabilities, the Company uses various valuation approaches. ASC 820, Fair Value Measurements and Disclosures Level 1 – Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Level 2 – Valuations based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and models for which all significant inputs are observable, either directly or indirectly. Level 3 – Valuations based on inputs that are unobservable and significant to the overall fair value measurement and that are based on management’s best estimate of inputs market participants would use for pricing the asset or liability at the measurement date, including assumptions about risk. The following table summarizes the Company’s fair value hierarchy for its financial assets and liabilities measured at fair value as of October 31, 2015: Total Level 1 Level 2 Level 3 Assets: Money market funds $ 12,517 $ 12,517 $ — $ — The following table summarizes the Company’s fair value hierarchy for its financial assets and liabilities measured at fair value as of January 31, 2015: Total Level 1 Level 2 Level 3 Assets: Money market funds $ 12,514 $ 12,514 $ — $ — The availability of observable inputs can vary among the various types of financial assets and liabilities. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for financial statement disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is categorized is based on the lowest level input that is significant to the overall fair value measurement.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	9. Commitments and Contingencies Legal Contingencies From time to time the Company is involved in legal proceedings arising in the ordinary course of business. There is no litigation pending that could, individually or in the aggregate, reasonably be expected to have a material adverse effect on the Company’s financial position, results of operations, or cash flows. Guarantees and Indemnification Obligations The Company enters into standard indemnification agreements in the ordinary course of business. Pursuant to these agreements, the Company indemnifies, holds harmless, and agrees to reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally the Company’s business partners or customers, in connection with any United States patent, or any copyright or other intellectual property infringement claim by any third party with respect to the Company’s products. The term of these indemnification provisions is generally perpetual after execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these agreements is unlimited. Based on historical experience and information known as of October 31, 2015 and January 31, 2015, the Company has not recorded any liabilities for these guarantees and indemnities. Operating Leases Effective July 1, 2015, the Company entered into an amendment to the lease for its corporate headquarters space in Burlington, Massachusetts. The amendment extends the lease term, originally set to expire in March 2016, through March 2023 and reduces the leased space from 65,941 square feet to 44,241 square feet. The 21,700 square foot reduction primarily relates to first floor space that had been subleased by the Company to a subtenant, and under the terms of the amendment, the landlord assumed the sublease effective July 1, 2015. The amendment also provides for a tenant improvement allowance of up to $1,681 to cover renovations that are being made to the retained second floor space over the remainder of fiscal year 2016. Management believes that the renovated space will be suitable and adequate to meet the Company’s planned growth needs at its headquarters over the next several years. In conjunction with the relinquishment of the first floor space, the amendment reduced the Company’s required security deposit letter of credit from $525 to $352. The reduction of the letter of credit is reflected as a change in restricted cash in the investing activity section of the accompanying consolidated statement of cash flows. Effective August 1, 2015, the Company entered into an amendment to the lease for its office space located in Japan. The amendment extends the lease term, originally set to expire in November 2015, through November 2017 and increases the leased space from approximately 4,047 square feet to 7,512 square feet. In conjunction with the purchase of additional computer processor equipment for its high performance computing data center in New Jersey described in Note 4, effective as of September 1, 2015, the Company’s hosting and support arrangement for that facility was expanded to account for the new equipment. As of October 31, 2015, after taking into consideration the above amendments, total future minimum lease payments under non-cancelable lease arrangements are as follows: Fiscal year ended January 31, 2016 (remainder as of October 31, 2015) $ 1,211 2017 4,711 2018 4,688 2019 4,209 2020 2,980 2021 2,086 Thereafter 3,942 $ 23,827

Equity [Abstract]
Stockholders' Equity and Stock-Based Compensation	10. Stockholders’ Equity and Stock-Based Compensation Warrants Exercised In July 2015, Massachusetts Capital Resource Company exercised warrants to purchase 21,538 shares of common stock at a cash exercise price of $6.11 per share. The Company has no remaining outstanding warrants as of October 31, 2015. Stock-Based Compensation Expense The fair value of common stock service-based options for employees and directors is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions used: Nine Months Ended 2015 2014 Estimated dividend yield 0 % 0 % Expected stock price volatility 36.8 % 47.4 % Weighted-average risk-free interest rate 2.0 % 2.2 % Expected life of options (in years) 6.23 6.25 The weighted-average grant date fair value per share for service-based stock options granted in the three and nine months ended October 31, 2015 was $4.14 and $4.21, respectively. The weighted average grant date fair value per share for service-based stock options granted in the three and nine months ended October 31, 2014 was $5.04 and $5.48, respectively. For standard service-based stock options, the Company records stock-based compensation expense over the estimated service/vesting period. The amount of stock-based compensation expense recognized during a period is based on the value of the portion of the awards that are ultimately expected to vest. Performance-based stock options are recognized as expense over the requisite service period when it becomes probable that performance measures triggering vesting will be met. Certain grants vested during the first quarter of fiscal year 2016 based on achieved performance metrics for fiscal year 2015. As of October 31, 2015, the Company concluded that it was probable that required metrics for certain performance-based grants would be achieved for fiscal year 2016. As a result, the Company recognized $228 in share-based compensation expense associated with these options. Total stock-based compensation expense related to stock options and restricted stock units issued by the Company is as follows: Three Months Ended Nine Months Ended 2015 2014 2015 2014 Cost of revenues $ 64 $ 52 $ 186 $ 134 Sales and marketing 117 88 317 249 Research and development 265 200 691 547 General and administrative 215 193 572 473 Total $ 661 $ 533 $ 1,766 $ 1,403 The total unrecognized compensation cost related to outstanding stock options is $4,224 at October 31, 2015. This amount is expected to be recognized over a weighted-average period of 2.45 years.

For the three and nine months ended October 31, 2014, the income tax provision was $214 and $15,870, respectively. The provision for the nine months ended October 31, 2014 includes a $14,506 non-cash charge to record a valuation allowance against the Company’s United States net deferred tax assets and a $700 non-cash write-off of state deferred tax assets. In determining the realizability of the net United States federal and state deferred tax assets, the Company considers numerous factors including historical profitability, estimated future taxable income, prudent and feasible tax planning strategies and the industry in which it operates. Management reassesses the realization of the deferred tax assets each reporting period, which resulted in a valuation allowance against the full amount of the Company’s United States deferred tax assets in the first quarter of fiscal year 2015. To the extent that the financial results of the United States operations improve in the future and the deferred tax assets become realizable, the Company will reduce the valuation allowance through earnings. The Company does not expect that its unrecognized tax benefit will change significantly within the next twelve months. The Company and one or more of its subsidiaries file United States federal income tax returns and tax returns in various state and foreign jurisdictions. With limited exceptions, the Company is no longer subject to federal, state, local or foreign examinations for years ending prior to January 31, 2011. However, carryforward attributes that were generated in tax years ending prior to January 31, 2012 may still be adjusted upon examination by state or local tax authorities if they either have been or will be used in a future period. Under Section 382 of the Internal Revenue Code of 1986, as amended, substantial changes in the Company’s ownership may limit the amount of net operating loss carryforwards that could be utilized annually in the future to offset its taxable income. Specifically, this limitation may arise in the event of a cumulative change in ownership of the Company of more than 50% within a three-year period. During the first quarter of fiscal year 2015, management determined that the Company had experienced an ownership change for purposes of Section 382. This ownership change resulted in annual limitations to the amount of net operating loss carryforwards that can be utilized to offset future taxable income, if any, at the federal level. The Company’s management has determined that, as of October 31, 2015, it had not experienced another ownership change for purposes of Section 382. However, future transactions in the Company’s common stock could trigger an ownership change for purposes of Section 382, which could limit the amount of net operating loss carryforwards that could be utilized annually in the future to offset the Company’s taxable income, if any. Any such limitation, whether as the result of sales of common stock by the Company’s existing stockholders or sales of common stock by the Company, could have a material adverse effect on the Company’s results of operations in future years.
