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 nongovernmental 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 accompanying unaudited consolidated financial statements have been prepared by the Company in accordance with GAAP for interim financial information and 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 footnotes required by GAAP for complete financial statements and should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended January 31, 2014 included in the Company’s Annual Report on Form 10-K. These financial statements reflect all adjustments (consisting solely of normal, recurring adjustments) that are, in the opinion of management, necessary for a fair statement of results for the interim periods presented.
	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. Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. 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, while reasonable when made, do not turn out to be substantially accurate.
	Recent Accounting Pronouncements
	In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (ASU 2013-11). ASU 2013-11 clarifies guidance and eliminates diversity in practice on the presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. This new guidance is effective for the Company in the first quarter of fiscal year 2015. The Company adopted ASU 2013-11 on February 1, 2014. This adoption did not have a material impact on the Company’s consolidated financial statements.

Computation of Net Loss Per Share	'
	3. Computation of Net Loss Per Share
	Net loss 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 per common share.
	The following summarizes the calculation of basic and diluted net loss per share:
		Three Months Ended April 30,
		2014			2013
	Numerator:
	Net loss	$	(17,220	)	$	(541	)

	Basic net loss per share	$	(1.28	)	$	(0.04	)
	Diluted net loss per share	$	(1.28	)	$	(0.04	)
	The following outstanding options, restricted stock unit awards and warrants were excluded from the computation of diluted net loss per share for the periods indicated because including them would have had an anti-dilutive effect:
		Three Months Ended April 30,
		2014			2013

	6. Deferred Rent
	In connection with its corporate headquarters lease entered into in July 2008, the Company received a tenant improvement allowance of $1,958 from the landlord. This lease incentive was recorded as leasehold improvements and deferred rent and is being amortized as part of rent expense on a straight-line basis over the life of the lease. The Company’s subsidiary Euroxa S.a.r.l. entered into a new office lease in Paris, France in May 2012 with a landlord incentive totaling $148, equivalent to four months free rent, which is also being amortized as rent expense on a straight line basis over the life of the lease. In addition, the Company’s facility leases typically contain other than straight-line payment features. The difference between the straight-line rent expense of the lease and the cash payments is recorded as deferred rent. Deferred rent as of April 30, 2014 and January 31, 2014 is as follows:
		April 30,			January 31,
		2014			2014
	Leasehold improvement incentive	$	506		$	572

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 April 30, 2014 and January 31, 2014, 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, establishes a hierarchy of inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability, and are developed based on the best information available in the circumstances. The fair value hierarchy is broken down into three levels based on the source of inputs as follows:
	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 April 30, 2014:
		Total		Level 1		Level 2		Level 3
	Assets:
	Money market funds	$	20,009	$	20,009	$	—	$	—
	The following table summarizes the Company’s fair value hierarchy for its financial assets and liabilities measured at fair value as of January 31, 2014:
		Total		Level 1		Level 2		Level 3
	Assets:
	Money market funds	$	15,008	$	15,008	$	—	$	—
	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.

	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, have a material adverse effect on the Company’s financial position, results of operations, or cash flows.
	In 2011, the Company was notified by the Massachusetts Institute of Technology, or MIT, that MIT believes that Exa is utilizing the intellectual property covered by a license agreement between the Company and MIT, and therefore is in arrears in the payment of royalties under the agreement. The Company has advised MIT that it does not believe that the Company utilized the underlying technology at any time since at least 1998, or that any royalties are owed under the agreement. MIT has not commenced suit against the Company with respect to its claims, and if any such suit is commenced by MIT, the Company intends to defend it vigorously. The Company believes that if MIT were to prevail in any such litigation, the royalties due under the terms of the license agreement, after giving effect to the approximately $200 in minimum royalties that the Company has already paid, would not exceed approximately $2,600 (excluding any interest or costs of litigation). The Company is not able to determine whether a loss is probable or estimate the reasonably possible or probable amount of such loss.
	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 April 30, 2014 and January 31, 2014, the Company has not recorded any liabilities for the above guarantees and indemnities.

Income Tax Disclosure [Abstract]	'
Income Taxes	'
	11. Income Taxes
	For the three months ended April 30, 2014, the Company’s income tax provision was $15.5 million which includes a $14.5 million non-cash charge to record a valuation allowance against its United States net deferred tax assets and a $0.7 million non-cash write-off of state deferred tax assets (discussed further below). Through the three months ended April 30, 2014, the Company’s results reflected a three-year cumulative loss position in the United States; prior thereto, the Company’s historical results reflected a three-year cumulative profit. Reflecting management’s plans to continue investing in the business for future growth, management’s projections reflect the Company continuing in a three-year cumulative loss position through fiscal year 2015. This historical and projected cumulative loss position caused management to modify its assessment of its deferred tax assets, concluding that it no longer was more likely than not that these deferred tax assets would be realized and thus, a valuation allowance was necessary against the full amount of its United States net deferred tax assets.
	Management will reassess the realization of the deferred tax assets each reporting period. To the extent that the financial results of the Company’s United States operations improve and the deferred tax asset becomes realizable, the Company will reduce the valuation allowance through earnings.
	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 can be utilized annually in the future to offset its United States federal 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 annual limit is approximately $14.0 million for fiscal year 2015, $16.8 million for each of fiscal years 2016 through 2019, $8.1 million for fiscal year 2020 and $6.4 million for each fiscal year thereafter. The ownership change also resulted in the loss of the Company’s ability to utilize $0.7 million of its $0.8 million of state net operating loss carryforwards, credits and other state attributes, which resulted in a write-off of the $0.7 million of state deferred tax assets during the first quarter of fiscal year 2015.
	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 prior to January 31, 2011. However, carryforward attributes that were generated prior to January 31, 2011 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.

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Apr. 30, 2014
Accounting Policies [Abstract]	'
Applicable Accounting Guidance	'
	Applicable Accounting Guidance
	Any reference in these notes to applicable accounting guidance is meant to refer to the authoritative nongovernmental United States generally accepted accounting principles (“GAAP”) as found in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”).
Basis of Presentation	'
	Basis of Presentation
	The accompanying unaudited consolidated financial statements have been prepared by the Company in accordance with GAAP for interim financial information and 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 footnotes required by GAAP for complete financial statements and should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended January 31, 2014 included in the Company’s Annual Report on Form 10-K. These financial statements reflect all adjustments (consisting solely of normal, recurring adjustments) that are, in the opinion of management, necessary for a fair statement of results for the interim periods presented.
Use of Estimates	'
	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. Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. 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, while reasonable when made, do not turn out to be substantially accurate.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (ASU 2013-11). ASU 2013-11 clarifies guidance and eliminates diversity in practice on the presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. This new guidance is effective for the Company in the first quarter of fiscal year 2015. The Company adopted ASU 2013-11 on February 1, 2014. This adoption did not have a material impact on the Company’s consolidated financial statements.
