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 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 included in the Company’s Annual Report on Form 10-K for the year ended January 31, 2015. 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. 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.
	Recent Accounting Pronouncements
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which supersedes nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle and, as a result of which, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP. The standard is effective for annual periods beginning after December 15, 2016, and interim periods therein. However, in April 2015, the FASB proposed a one-year deferral that does not require adoption until calendar year 2018 (fiscal 2019 for the Company). The two permitted transition methods under the new standard are: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). The Company is currently evaluating the impact of its pending adoption of ASU 2014-09 on its consolidated financial statements and has not yet determined the method by which it will adopt the standard when it becomes effective.
	In June 2014, the FASB issued ASU 2014-12, Stock Compensation, which is a standards update on accounting for share-based payments when the terms of the award provide that a performance target could be achieved after a requisite service period. The standard is effective for annual periods beginning after December 31, 2015, and interim periods therein, with early adoption permitted. This ASU is not expected to have an impact on the Company’s financial statements or disclosures.
	In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. Under the new guidance, management will be required to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosures in certain circumstances. The provisions of this ASU are effective for annual periods beginning after December 15, 2016, and for interim periods therein. This ASU is not expected to have an impact on the Company’s financial statements or disclosures.

Earnings Per Share [Abstract]
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,
		2015			2014
	Numerator:
	Net loss	$	(1,888	)	$	(17,220	)

	Basic net loss per share	$	(0.13	)	$	(1.28	)
	Diluted net loss per share	$	(0.13	)	$	(1.28	)
	The table below represents outstanding options, restricted stock unit awards and warrants that 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. All of the Company’s outstanding stock options, unvested restricted stock units and warrants were anti-dilutive for the three months ended April 30, 2015 and 2014 due to the net loss position of the Company.

Deferred Rent	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 related to four months free rent, which is also being amortized as part of rent expense on a straight line basis over the life of the lease. In addition, the Company’s facility leases typically contain other 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 is as follows:
		April 30,			January 31,
		2015			2015
	Leasehold improvement incentive	$	242		$	308
	Non-cash rent expense		726			761

Fair_Value_Measurements

Fair Value Measurements	3 Months Ended

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, 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, 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, 2015:
		Total		Level 1		Level 2		Level 3
	Assets:
	Money market funds	$	12,515	$	12,515	$	—	$	—
	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.

	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, be reasonably 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 April 30, 2015 and January 31, 2015, the Company has not recorded any liabilities for the above guarantees and indemnities.

Stock-Based Compensation	10. Stock-Based Compensation
	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:
		Three Months Ended
		April 30,
		2015			2014
	Estimated dividend yield		0	%		0	%
	Expected stock price volatility		39	%		49.8	%
	Weighted-average risk-free interest rate		1.8	%		2.2	%
	Expected life of options (in years)		6.25			6.25
	The weighted average grant date fair value per share for service-based stock options granted in the three months ended April 30, 2015 was $4.27.
	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. As a result, the Company recognized $108 in share-based compensation expense associated with these performance-based options during the three months ended April 30, 2015. Furthermore, as of April 30, 2015, the Company has concluded that it is not probable that the remaining unvested options will achieve the required metrics for vesting. As a result, the Company has not recognized any additional share-based compensation expense associated with the unvested portion of these performance-based options.
	Total stock-based compensation expense related to stock options and restricted stock units issued by the Company is as follows:
		Three Months Ended
		April 30,
		2015			2014
	Cost of revenues	$	69		$	38

	General and administrative		189			101
	Total	$	614		$	370
	The total unrecognized compensation cost related to outstanding service-based stock options is $3,464 at April 30, 2015. This amount is expected to be recognized over a weighted-average period of 2.61 years.

Income Tax Disclosure [Abstract]
Income Taxes	11. Income Taxes
	For the three months ended April 30, 2015, the Company’s income tax benefit was $26. For the three months ended April 30, 2014, the Company’s income tax provision was $15,480. The benefit for the three months ended April 30, 2015 primarily consists of the tax effect of foreign losses, offset by withholding taxes. The provision for the three months ended April 30, 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 full valuation allowance against 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 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 April 30, 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.

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Apr. 30, 2015
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 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 included in the Company’s Annual Report on Form 10-K for the year ended January 31, 2015. 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. 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.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which supersedes nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle and, as a result of which, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP. The standard is effective for annual periods beginning after December 15, 2016, and interim periods therein. However, in April 2015, the FASB proposed a one-year deferral that does not require adoption until calendar year 2018 (fiscal 2019 for the Company). The two permitted transition methods under the new standard are: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). The Company is currently evaluating the impact of its pending adoption of ASU 2014-09 on its consolidated financial statements and has not yet determined the method by which it will adopt the standard when it becomes effective.
	In June 2014, the FASB issued ASU 2014-12, Stock Compensation, which is a standards update on accounting for share-based payments when the terms of the award provide that a performance target could be achieved after a requisite service period. The standard is effective for annual periods beginning after December 31, 2015, and interim periods therein, with early adoption permitted. This ASU is not expected to have an impact on the Company’s financial statements or disclosures.
	In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. Under the new guidance, management will be required to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosures in certain circumstances. The provisions of this ASU are effective for annual periods beginning after December 15, 2016, and for interim periods therein. This ASU is not expected to have an impact on the Company’s financial statements or disclosures.
