Summary of Significant Accounting Policies	'
	Note 2. Summary of Significant Accounting Policies
	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States, or GAAP, requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the related disclosure of contingent assets and liabilities in the financial statements and the accompanying notes. Significant estimates include the estimates relating to revenue recognition, the useful lives of fixed assets, stock-based compensation, assumptions used in estimating the fair value of warrants, assumptions used in testing for impairment of goodwill and other long-lived assets, and the recoverability of deferred income tax assets and liabilities. Actual results could differ from those estimates, and such differences may be material to the consolidated financial statements.
	Principles of Consolidation
	The consolidated financial statements include the accounts of Jive Software, Inc. and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
	Reclassification
	Certain prior year amounts have been reclassified to conform to current year presentation. These reclassifications were not significant to the financial statements.
	Segments
	An operating segment is defined as a component of an enterprise that meets the following criteria:
		•		engages in business activities from which it may earn revenues and incur expenses;
		•		operating results are regularly reviewed by the enterprise’s chief operating decision maker to make decisions about resources to be allocated to the segment and assess its performance; and
		•		discrete financial information is available.
	We define the term “chief operating decision maker” to be our Chief Executive Officer. Our Chief Executive Officer reviews financial information presented on a consolidated basis, accompanied by information about revenue by product line and geographic region for purposes of allocating resources and evaluating financial performance. We have one business activity and there are no segment managers who are held accountable for operations, operating results or plans for levels or components below the consolidated unit level. Accordingly, we have determined that we operate in a single reporting segment, software sales and service.
	Revenue Recognition
	We generate revenues in the form of product fees and related professional service fees. Product fees include subscription fees, perpetual license fees, associated support and maintenance fees and hosting fees. Professional services primarily consist of fees for strategic consulting, configuration, training, consultation and implementation services, which are not essential to the functionality of the software. For statement of operations classification purposes, we allocate revenues to professional services based on the hourly rate billed for time and materials arrangements and based on the total fixed fee for fixed fee professional services. We recognize revenue when all of the following conditions are met:
		•		there is persuasive evidence of an arrangement;
		•		the product or services have been delivered to the customer;
		•		the amount of fees to be paid by the customer is fixed or determinable; and
		•		the collection of the related fees is reasonably assured.
	Signed agreements are used as evidence of an arrangement. If a contract signed by the customer does not exist, we have historically used a purchase order as evidence of an arrangement. In cases where both a signed contract and a purchase order exist, we consider the signed contract to be the final persuasive evidence of an arrangement. Software and corresponding license keys are delivered to customers electronically. Electronic delivery occurs when we provide the customer with access to the software. We assess whether a fee is fixed or determinable at the outset of the arrangement, primarily based on the payment terms associated with the transaction. We do not generally offer extended payment terms with typical terms of payment due between 30 and 60 days from delivery of solutions or services. For professional services that are billable under a time and materials based arrangement, these fees are neither fixed nor determinable until the work is performed and the fee becomes billable to the customer. We assess collectability of the customer receivable based on a number of factors such as collection history with the customer and creditworthiness of the customer. If we determine that collectability is not reasonably assured, revenue is deferred until collectability becomes reasonably assured, generally upon receipt of cash.
	We offer subscriptions of our platform to customers most frequently on a term basis with terms typically ranging from 12 to 36 months. While term-based licenses make up the majority of our total revenues, we occasionally license our solutions to customers on a perpetual basis with on-going support and maintenance services. We recognize license revenue in accordance with software industry specific guidance. Revenues related to term license fees are recognized ratably over the contract term beginning on the date the customer has access to the software license key and continuing through the end of the contract term. For term-based licenses, we do not charge separately for standard support and maintenance, and, therefore, inherent in the license fees are fees for support and maintenance services for the duration of the license term. As fees for support and maintenance are always bundled with the license over the entire term of the contract, we do not have vendor-specific objective evidence (“VSOE”) of fair value for support and maintenance. Revenues generated from perpetual license sales also include support and maintenance services for an initial stated term, both the perpetual license and support and maintenance are recognized ratably over the initial stated term. We do not have VSOE of fair value for support and maintenance on perpetual licenses as we have not had sufficient consistently priced standalone sales of support and maintenance, nor have we offered substantive renewal rates for support and maintenance. Additionally, customers who have purchased perpetual licenses to the base platform have historically also purchased term-based subscriptions to certain of our modules. We do not have VSOE of fair value for either the support and maintenance on the perpetual license or the module and, therefore, revenue is recognized ratably over the longer of the initial maintenance term for the perpetual license or the term for the subscription elements.
	License arrangements may also include professional services, such as strategic consulting installation, upgrades and training services, which are typically delivered early in the contract term. This combination of products and services represents a multiple-element arrangement for revenue recognition purposes. We have determined that we do not have VSOE of fair value for each element of a multiple-element sales arrangement and, accordingly, we account for fees received under that multiple-element arrangement as a single unit of accounting and recognize the fees for the entire arrangement ratably, commencing on delivery of the software, over the longer of the term of the support and maintenance or the period over which professional services are delivered. Support and maintenance is always the last undelivered element in the arrangement and, therefore, we recognize the fixed portion of the fees ratably over the support and maintenance term. For contracts with multiple elements, we recognize the license, support and maintenance, and fixed fee professional service revenue ratably over the term of the arrangement beginning upon delivery of the software. We believe this method most closely reflects the economics of the transaction as we deliver access to the software and we begin providing support and maintenance services as of the date the software is delivered.
	Professional services are offered on both fixed fee and time and materials hourly billing arrangements. For time and materials-based professional services that are part of a multiple-element arrangement where the fees for the professional services are not fixed or determinable upon delivery of the software, revenue is recognized ratably over the contract term as the related fees become fixed. These fees are not considered fixed at the outset of the arrangement and become fixed as the related work is performed and the fees are earned and billed. These services are typically provided early in the contract term with completion typically occurring in the first six months. As these fees become fixed, they are added to the total fee for the multiple-element arrangement and recognized ratably with all other arrangement fees over the entire contract term. When billed, a cumulative revenue catch-up is calculated as the revenue earned from the date the software was made available to the customer to the date services have been completed, with recognition continuing ratably to the end of the contract term. These amounts, when recognized in our Consolidated Statements of Operations, are classified as professional services revenues based on the hourly rates at which they are billed. If there are significant acceptance clauses associated with the license or services or uncertainty associated with our ability to perform the professional services, revenues are deferred until the acceptance is received or the uncertainty is resolved. We record amounts that have been invoiced, in accordance with the terms of the agreement, in accounts receivable and in deferred revenues or revenues, depending on whether the revenue recognition criteria have been met.
	Hosting revenues are derived from providing our software solutions in a hosted environment where the customer does not take possession of the software on their premises. With the exception of the Jive Cloud licensing model, customers have the option to elect to take possession of the software and install on their premises or sub-contract the hosting services through us. Such arrangements are considered software sales as the customer has the same rights to the software license regardless of their election to have us host on their behalf or install on their premises. As a result, the fees associated with license, support and hosted services are recognized as revenue ratably over the term of the arrangement. For Jive Cloud licensing arrangements, customers do not have the right to take possession of the software supporting the cloud-based application service at any time.
	We occasionally sell professional services separately and recognize revenues resulting from those as professional services are performed. If there is a significant uncertainty about the project completion or receipt of payment for the consulting services, revenues are deferred until the uncertainty is resolved. If acceptance provisions exist within a professional services arrangement, revenues will be deferred until the services are accepted, the acceptance period has expired or cash is received from the customer.
	Taxes Collected from Customers and Remitted to Governmental Authorities
	We account for tax assessed by a governmental authority that is directly imposed on a revenue-producing transaction (i.e., sales, use, value added) on a net (excluded from revenue) basis.
	Cash and Cash Equivalents
	We consider all highly liquid investments with an original maturity of three months or less to be cash equivalents. Our cash balances with financial institutions may exceed the deposit insurance limits. Included in cash and cash equivalents were cash equivalents of $6.7 million and $0.5 million at December 31, 2013 and 2012, respectively. Cash equivalents are stated at cost, which approximates market value.
	Accounts Receivable and Allowance for Doubtful Accounts
	Accounts receivable are carried at their original invoice amounts less the allowance for doubtful accounts and do not bear interest. Our policy is to maintain an allowance for estimated losses resulting from the inability or refusal of our customers to make required payments. In establishing the required allowance, management considers historical losses adjusted to take into account current market conditions and the customers’ financial condition, the amount of receivables in dispute, and the current receivables aging and current payment patterns. On a quarterly basis, we evaluate the collectability of our trade receivable balances based on a combination of factors. Past due balances over 90 days and over a specified amount are reviewed individually for collectability. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. If the financial conditions of our customers were to materially change or there were other circumstances that resulted in their inability or unwillingness to pay, the estimates of recoverability of receivables could materially change.
	Activity related to our allowance for doubtful accounts was as follows (in thousands):

	Charges to costs and expenses			672
	Write-offs			(150	)
	Balance, December 31, 2013		$	740
	Fair Value of Financial Assets and Liabilities
	The carrying value of cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable, accrued payroll and related liabilities and other accrued liabilities approximates their fair values due to the short-term nature of their maturities. The fair value of the long-term debt approximates its carrying value since the interest rate is variable and based on current market rates.
	Property and Equipment
	Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives as follows:
		•		three years for computer equipment, hardware and software;
		•		seven years for furniture, fixtures and equipment; and
		•		the lesser of five years or the remaining term of the underlying lease for leasehold improvements.
	Ordinary maintenance and repairs are expensed as incurred.
	Research and Development
	We expense research and development costs, including costs to develop software products to be marketed to external users, before technological feasibility of such products is reached. We believe our software development process is essentially completed concurrent with the establishment of technological feasibility; accordingly, development costs are expensed as incurred.
	Internal-Use Software Development Costs
	We capitalize costs to develop internal-use software during the application development stage. Costs related to preliminary project activities and post implementation activities are expensed as incurred. Capitalized software is included in property and equipment and is depreciated over the useful life when placed in service. Management evaluates the useful lives of these assets and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets.
	During 2013, we capitalized $3.1 million of such costs. Depreciation of these capitalized costs has not started as of December 31, 2013, as the related project is still in development. There were no internal-use software development costs capitalized in 2012 and 2011.
	Accounting for the Impairment of Long-Lived Assets
	We evaluate the recoverability of our long-lived assets, which principally consist of property and equipment and acquired intangible assets with finite lives, whenever events or circumstances indicate that the carrying amount of these assets may not be recoverable. Recoverability of an asset is measured by comparing the carrying amount to the expected future undiscounted cash flows that the asset is expected to generate. If that review indicates that the carrying amount of the long-lived asset is not recoverable, an impairment loss is recorded for the amount by which the carrying amount of the asset exceeds its fair value.
	We did not incur any long-lived asset impairment charges in the years ended December 31, 2013, 2012 or 2011.
	Goodwill
	Goodwill represents the excess of the purchase price over the estimated fair value of the net tangible and intangible assets of acquired entities. We perform a goodwill impairment test annually during the fourth quarter of our fiscal year and more frequently if an event or circumstance indicates that an impairment may have occurred. Such events or circumstances may include significant adverse changes in the general business climate, among other things.
	Beginning in 2012, we are allowed to first make a qualitative assessment to determine whether it is more likely than not that goodwill is impaired before applying the two-step goodwill impairment test. If the conclusion is that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we then perform a two-step goodwill impairment test. During 2013 and 2012, we elected to forgo the qualitative assessment, and proceeded to the first step of the test for goodwill impairment. Under the first step, the fair value of the reporting unit is compared with its carrying value, and, if an indication of goodwill impairment exists for the reporting unit, we must perform step two of the impairment test (measurement). Under step two, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill as determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation. The residual fair value after this allocation is the implied fair value of the reporting unit goodwill. If the fair value of the reporting unit exceeds its carrying value, step two does not need to be performed. If the carrying amount of goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. We did not record any charges related to goodwill impairment during the years ended December 31, 2013, 2012 or 2011.
	Intangible Assets
	Definite-lived intangible assets are amortized using the straight-line method over estimated useful lives and have no significant residual value. Definite-lived intangible assets are reviewed for impairment as discussed above under “Accounting for the Impairment of Long-Lived Assets.”
Other Assets
Other assets include deposits for facilities leases and other miscellaneous long-term assets.
Deferred Revenue
Deferred revenue consists of billings or payments received in advance of revenue recognition from our subscription license, perpetual license, hosting, professional services and support and maintenance revenues described above and are recognized as the revenue recognition criteria are met. We generally invoice our customers in annual installments. Accordingly, the deferred revenues balance does not represent the total contract value of annual or multi-year non-cancelable subscription agreements. Deferred revenue also includes certain deferred professional services fees, which are recognized as revenues ratably over the associated contract term. We defer the professional service fees in situations where the professional services and subscription or perpetual contracts are accounted for as a single unit of accounting. Deferred revenue that will be recognized during the succeeding 12-month period is recorded as current deferred revenue, and the remaining portion is recorded as noncurrent. Approximately 4% and 5% of total deferred revenue as of December 31, 2013 and 2012, respectively, related to deferred professional services revenues.
Concentration of Risk
Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and trade receivables. Cash is placed on deposit in major financial institutions in the United States. Such deposits may be in excess of insured limits. Management believes that the financial institutions that hold our cash deposits are financially sound and, accordingly, minimal credit risk exists with respect to these balances.
We sell our products to companies in diverse industries and do not require our customers to provide collateral to support accounts receivable. When necessary, credit reviews of significant customers are performed prior to extending credit. The determination of a customer’s ability to pay requires significant judgment, and failure to collect from a customer can adversely affect revenues, cash and net income.
No individual customer accounted for 10% or more of total revenues in the years ended December 31, 2013, 2012 or 2011. One customer accounted for 14% of accounts receivable at December 31, 2013. No customer accounted for 10% or more of total accounts receivable at December 31, 2012.
Stock-Based Compensation
We recognize compensation expense for all share-based payment awards, including stock options and restricted stock, based on the estimated fair value of the award on the grant date. We use the Black-Scholes-Merton valuation model to estimate the fair value of stock option awards. The fair value of the awards is recognized as expense, net of estimated forfeitures, over the requisite service period, which is generally the vesting period of the respective award.
Stock-based compensation expense is recognized for performance-based restricted stock awards based on the probability of achieving certain performance criteria. We estimate the number of performance-based restricted stock awards ultimately expected to vest and recognize expense using the graded vesting attribution method over the requisite service period.
The determination of the grant date fair value of options using an option-pricing model is affected by assumptions regarding a number of other complex and subjective variables, which include our expected stock price volatility over the expected term of the options, stock option exercise and cancellation behaviors, risk-free interest rates and expected dividends. In addition, prior to our initial public offering (“IPO”) in December 2011, we also made assumptions regarding the fair value of our common stock.
Income Taxes
We record deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement carrying amounts and the tax basis of the assets and liabilities. Deferred tax assets are reduced by a valuation allowance when it is estimated to be more likely than not that a portion of the deferred tax assets will not be realized.
We recognize the effect of income tax positions only if those positions are “more likely than not” of being sustained. Interest and penalties accrued on unrecognized tax benefits are recorded as tax expense within our consolidated financial statements.
Warranties
We typically warrant that our products will perform in a manner consistent with the product specifications provided to the customer for 180 days for sales to companies in the United States and 365 days for sales to companies in Europe. Historically, we have not been required to make payments under these obligations, and we have not recorded any liability for these obligations in our consolidated financial statements.
Commissions
Commissions are recorded as a component of sales and marketing expenses and consist of the variable compensation paid to our direct sales force. Generally, sales commissions are earned and recorded as an expense at the time that a customer has entered into a binding purchase agreement. Commissions paid to sales personnel are recoverable only in the case that we cannot collect against any invoiced fee associated with a sales order. Commission expense was $15.7 million, $12.9 million and $9.2 million, for the years ended December 31, 2013, 2012 and 2011, respectively.
Leases
We lease our facilities under operating leases. For leases that contain rent escalation or rent concession provisions, we record the total rent expense during the lease term on a straight-line basis over the term of the lease. We record the difference between the rent paid and the straight-line rent expense as a deferred rent liability in other long-term liabilities in the accompanying Consolidated Balance Sheets.
Advertising Costs
Advertising costs are expensed as incurred as a component of sales and marketing expense and totaled $5.3 million, $4.9 million and $2.2 million for the years ended December 31, 2013, 2012 and 2011, respectively.
Legal Costs
We are a party to legal proceedings arising in the normal course of business. Legal costs are expensed as incurred as a component of general and administrative expense.
Net Loss Per Share
Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period, less the weighted-average unvested common stock subject to repurchase or forfeiture. Diluted net loss per share is computed by giving effect to all potential shares of common stock, including preferred stock, stock options and warrants, to the extent dilutive. Since we were in a loss position for all periods presented, basic and diluted net loss per share was the same for each period presented as the inclusion of all potential common shares outstanding would have been anti-dilutive.
Foreign Currency Translation
The functional currency of our foreign subsidiaries is the local currency. Adjustments resulting from translating foreign functional currency financial statements into U.S. dollars are recorded as a separate component of stockholders’ deficit. Income and expense accounts are translated into U.S. dollars at average rates of exchange prevailing during the periods presented. Foreign currency transaction gains and losses are included in net loss. All assets and liabilities denominated in a foreign currency are translated into U.S. dollars at the respective exchange rates in effect on the consolidated balance sheet dates. Foreign currency transaction gains and losses were not material in the years ended December 31, 2013, 2012 or 2011.

Business Combinations [Abstract]	'
Acquisitions	'
	Note 3. Acquisitions
	2013
	Clara Ehf. (“Clara”)
	On April 18, 2013, we acquired substantially all of the assets and certain related liabilities of Clara, a private limited company founded in Iceland that provides a cloud-based analytics tool that allows businesses to understand, monitor and actively engage with community members within online platforms. The total purchase consideration of approximately $6.5 million was comprised entirely of cash.
	The allocation of the purchase price was as follows (dollars in thousands):
					Useful Life
	Current assets	$	81
	Goodwill		3,161			—
	Other intangible assets:					—
	Core technology		2,315			5 years
	Covenant not to compete		227			2 years
	Customer relationships		570			3 years
	Trade names		230			3 years
			3,342
	Current liabilities		(96	)		—
	Net assets acquired	$	6,488
	The key factor attributable to the creation of goodwill by the transaction is the synergies created by the integration of the Clara analytics technology with our social platform, for both internal and external communities. All of the goodwill is expected to be deductible for income tax purposes.
	The weighted average amortization period for all intangible assets acquired is 4.3 years.
	Transaction costs of $0.2 million associated with the acquisition of Clara were expensed as incurred as a component of general and administrative expenses on our Consolidated Statements of Operations.
	Clara’s results of operations have been included in our consolidated financial statements subsequent to the date of acquisition. Pro forma results of operations have not been presented because the effect of the acquisition was not material to prior period financial statements. Revenue and earnings information since the date of acquisition was not material to the current period financial statements.
	StreamOnce, Inc. (“StreamOnce”)
	On April 29, 2013, we acquired all of the outstanding shares of StreamOnce, whose product offers a platform that connects third-party information streams directly into our Jive Social Business Platform, integrating disparate information systems for increased productivity. The total initial purchase consideration was comprised of $4.7 million in cash and 532,952 shares of our common stock with a fair value on April 29, 2013 of $7.3 million. Of the 532,952 shares of common stock, 470,552 shares of common stock issued to certain StreamOnce employees vest over a two-year period contingent upon the continued employment of the recipients. The fair value of these shares on the grant date was $6.4 million, which is being recognized as stock-based compensation over the two-year vesting period. Additionally, certain StreamOnce employees may receive additional consideration, not to exceed $0.7 million, if our sales and customer count relating to the acquired business exceed certain thresholds over an 18-month period commencing as of the acquisition date (the “Earnout”).
	We recorded a contingent consideration liability of approximately $0.6 million within other accrued liabilities in our Consolidated Balance Sheets as of the acquisition date related to the Earnout. The fair value of the liability was estimated using internal forecasts with inputs that are not observable in the market, and thus represents a Level 3 fair value measurement as defined within Note 7. The inputs in the Level 3 measurement are not supported by market activity, as they are probability assessments of expected future sales and customer count related to our acquisition of StreamOnce during the Earnout period. The Earnout is remeasured quarterly, with the change being reflected as a component of research and development in our Consolidated Statements of Operations. See Note 7 for additional information.
	The allocation of the purchase price was as follows (dollars in thousands):
	Cash paid	$	4,667
	Value of common stock issued		852
	Contingent consideration		576
	Total transaction consideration:	$	6,095
					Useful Life
	Current assets	$	108			—
	Goodwill		3,157			—
	Other intangible assets:
	Core technology		3,671			5 years
	Covenant not to compete		459			3 years
	Trade names		118			3 years
			4,248
	Current liabilities		(67	)		—
	Deferred tax liability		(1,351	)		—
	Net assets acquired	$	6,095
	The goodwill recorded in connection with the acquisition of StreamOnce is primarily related to the ability of StreamOnce to increase viral adoption of the Jive platform within our customers by integrating their existing third-party business applications with our platform and from the expected synergies to be achieved in connection with the acquisition. None of the goodwill is expected to be deductible for income tax purposes.
	The weighted average amortization period for all intangible assets acquired is 4.7 years.
	In connection with the StreamOnce acquisition, a deferred tax liability of $1.4 million was established for the book and tax basis differences related to specifically identified non-goodwill intangibles. The net liability from the acquisition created an additional source of income to utilize our deferred tax assets and, therefore, a corresponding amount of the valuation allowance was released and recorded as a benefit from income taxes.
	Transaction costs of $0.2 million associated with the acquisition of StreamOnce were expensed as incurred as a component of general and administrative expenses on our Consolidated Statements of Operations.
	StreamOnce’s results of operations have been included in our Consolidated Financial Statements subsequent to the date of acquisition. Pro forma results of operations have not been presented because the effect of the acquisition was not material to prior period financial statements. Revenue and earnings information since the date of acquisition was not material to the current period financial statements.
	2012
	Producteev LLC
	On November 21, 2012, we acquired all of the outstanding shares of Producteev LLC (“Producteev”), a cloud-based project and task management company. The total purchase consideration of $7 million was comprised of cash.
	The allocation of the purchase price was as follows (dollars in thousands):
					Useful Life
	Current assets	$	28			—
	Goodwill		4,186			—
	Other intangible assets:
	Core technology		2,127			5 years
	Covenant not to compete		272			3 years
	Customer relationships		421			3 years
	Trade names		284			4 years
			3,104
	Current liabilities		(70	)		—
	Deferred tax liabilities		(241	)		—
	Net assets acquired	$	7,007
	The key factors attributable to the creation of goodwill by the transaction are the synergies associated with the integration of the Producteev task-management product into our social platform.
	The weighted average amortization period for all intangible assets acquired is 4.5 years.
	See Note 11, “Income Taxes” regarding the tax effect of the acquisition on our consolidated financial statements.
Transaction costs of $0.2 million associated with the acquisition of Producteev were expensed as incurred as a component of general and administrative expenses on our Consolidated Statements of Operations.
Producteev’s results of operations have been included in our consolidated financial statements subsequent to the date of acquisition. Pro forma results of operations have not been presented because the effect of the acquisition was not material to prior period financial statements. Revenue and earnings information since the date of acquisition was not material to the current period financial statements.
Meetings.io
On November 5, 2012, we acquired all of the outstanding shares of Meetings.io, a cloud-based real-time video, chat and screen sharing collaboration company. The total purchase consideration of $3.0 million was comprised of $0.6 million in cash and 211,936 shares of our common stock with a fair value on November 5, 2012 of $2.4 million.
We also issued 248,064 shares of restricted common stock to certain Meetings.io employees which vest over a three year period contingent upon the continued employment of the recipients. The fair value of these shares on the grant date was $2.8 million, which is being recognized as stock-based compensation over the three-year vesting period.
The allocation of the purchase price was as follows (dollars in thousands):
				Useful Life
Current assets	$	27			—
Goodwill		1,984			—
Other intangible assets:
Core technology		764			5 years
Covenant not to compete		263			3 years
		1,027
Current liabilities		(3	)		—
Deferred tax liabilities		(40	)		—
Net assets acquired	$	2,995
We do not expect the goodwill to be deductible for tax purposes. Intangible assets acquired included core technologies and covenants not to compete. The key factors attributable to the creation of goodwill by the transaction are the synergies associated with the integration of the Meetings.io real-time features into our social platform.
The weighted average amortization period for all intangible assets acquired is 4.5 years.
See Note 11, “Income Taxes” regarding the tax effect of the acquisition on our consolidated financial statements.
Transaction costs of $0.2 million associated with the acquisition of Meetings.io were expensed as incurred as a component of general and administrative expenses on our Consolidated Statements of Operations.
Meetings.io’s results of operations have been included in our consolidated financial statements subsequent to the date of acquisition. Pro forma results of operations have not been presented because the effect of the acquisition was not material to prior period financial statements. Revenue and earnings information since the date of acquisition was not material to the current period financial statements.
2011
OffiSync Corporation
On May 18, 2011 we acquired all of the outstanding shares of OffiSync Corporation (“OffiSync”), a Seattle, Washington-based company, for approximately $22.7 million in cash and 78,110 shares of our common stock at a fair value of $7.87 per share, for a total value of $23.3 million. OffiSync’s services facilitate collaboration on any Microsoft Office document.
We also issued 441,102 shares of restricted common stock to certain OffiSync employees, the fair value of these shares on the grant date was $3.5 million, which is being recognized as stock-based compensation over the three-year vesting period. In addition, unvested stock options, for which no service was performed prior to acquisition, held by OffiSync employees who were retained were converted to 80,788 Jive common stock options.
The allocation of the purchase price was as follows (dollars in thousands):
				Useful Life
Cash	$	275
Other current assets		54			—
Goodwill		16,434			—
Other intangible assets:
Core technology		9,992			5 years
Covenant not to compete		365			2 years
Customer relationships		212			2 years
Trade names		28			2 years
		10,597
Current liabilities		(226	)		—
Deferred tax liabilities		(3,851	)		—
Net assets acquired	$	23,283
The amount of the purchase price allocated to core technology, covenant not to compete, customer relationships and trade names will be amortized on a straight-line basis over their estimated useful lives.
The goodwill recorded in connection with the acquisition of OffiSync is primarily related to the ability of OffiSync to increase viral adoption with our users by integrating both Microsoft Office and Outlook with our Platform and from the expected synergies to be achieved in connection with the acquisition. We do not expect the goodwill to be deductible for tax purposes.
The weighted average amortization period for all intangible assets acquired is 4.8 years.
See Note 11, “Income Taxes” regarding the tax effect of the acquisition on our consolidated financial statements.
Transaction costs of $0.5 million associated with the acquisition of OffiSync were expensed as incurred as a component of general and administrative expenses on our Consolidated Statements of Operations.
Pro forma results assuming that the OffiSync acquisition had occurred as of January 1, 2010 were as follows (in thousands):
	Year Ended December 31,
	2011			2010
Revenue	$	77,358		$	46,318
Net loss	$	(56,445	)	$	(37,154	)
Proximal Labs, Inc.
On March 18, 2011 we acquired all of the outstanding shares of Proximal Labs, Inc. (“Proximal Labs”), a privately held Palo Alto, California-based company, for total purchase consideration of $1.2 million. The consideration was comprised of $0.5 million in cash and 127,054 shares of our common stock.
We also issued 272,946 shares of restricted common stock to certain Proximal Labs employees, the fair value of these shares on the grant date was $1.2 million, which is being recognized as stock-based compensation expense over the four-year vesting period.
The acquisition of Proximal Labs has been accounted for as a purchase of an asset, as it did not meet the definition of a business. Accordingly, the total purchase price was allocated to the identified assets based on their respective fair values on the date of acquisition.
The allocation of the purchase price was as follows (dollars in thousands):
				Useful Life
In-process research and development	$	1,031			—
Covenant not to compete		209			3 years
Net assets acquired	$	1,240
The amount of the purchase price allocated to non-compete agreements will be amortized on a straight-line basis over the estimated useful life of three years. The amount of the purchase price allocated to in-process research and development was expensed upon acquisition, because the technological feasibility of product under development had not been established.

Fair Value Measurements of Assets and Liabilities	'
	Note 7. Fair Value Measurements of Assets and Liabilities
	Factors used in determining the fair value of financial assets and liabilities are summarized into three broad categories:
		•		Level 1 – quoted prices in active markets for identical securities as of the reporting date;
		•		Level 2 – other significant directly or indirectly observable inputs, including quoted prices for similar securities, interest rates, prepayment speeds and credit risk; and
		•		Level 3 – significant inputs that are generally less observable than objective sources, including our own assumptions in determining fair value.
	The factors or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.
	The following table presents our financial assets that were measured at fair value on a recurring basis as of December 31, 2013 and 2012 (in thousands):

	Balance at December 31, 2013		$	726
	We classify our marketable securities as available-for-sale and, accordingly, record them at fair value based on quoted market prices. Unrealized holding gains and losses are excluded from earnings and are reported as a separate component of stockholders’ equity until realized. See the Consolidated Statements of Comprehensive Loss.
	During 2013, 2012 and 2011, we did not record any other-than-temporary impairments on those financial assets required to be measured at fair value on a nonrecurring basis.
	We recognize or disclose the fair value of certain assets such as non-financial assets, primarily long-lived assets, goodwill, intangible assets and certain other assets in connection with impairment evaluations. All of our nonrecurring valuations use significant unobservable inputs and therefore fall under Level 3 of the fair value hierarchy.
	The carrying value of our term loan approximates its fair value and falls under Level 2 of the fair value hierarchy, as the interest rate is variable and based on current market rates.
	Our contingent consideration was re-measured at fair value as of December 31, 2013 and falls under Level 3 of the fair value hierarchy, as the forecasted bookings and customer count are based on internal forecasts, and are not directly observable.
	We did not have any financial liabilities that were measured at fair value on a recurring basis at December 31, 2012.
	There were no changes to our valuation techniques during 2013.

Debt Disclosure [Abstract]	'
Long-Term Debt	'
	Note 8. Long-Term Debt
	Credit Facility with Silicon Valley Bank
	In May 2012, we entered into a loan agreement with Silicon Valley Bank (the “Loan Agreement”), which provides a secured revolving loan facility and term loan facility of up to $30.0 million and expires May 23, 2015. Under the Loan Agreement, revolving loans may be converted into term loans under the facility, subject to specified conditions, with all outstanding term loans reducing the availability under the revolving loan facility. The Loan Agreement also provides up to $3.0 million for the issuance of letters of credit, foreign exchange contracts, cash management services and secured swap obligations. On May 23, 2012, we converted the outstanding balance of pre-existing term loans with Silicon Valley Bank to a new term loan for $12.0 million under the Loan Agreement and terminated the previous credit facility agreement. Revolving loans drawn under the Loan Agreement will be used for working capital, potential acquisitions, and general corporate purposes.
	Revolving loans bear interest, at our option, at:
		(i)	an adjusted LIBOR rate, plus a margin of 1.75% or 2.0%; or
		(ii)	the prime rate published in the Wall Street Journal, plus a margin of 0% or 0.25%.
	Term loans bear interest, at our option, at
		(i)	an adjusted LIBOR rate, plus a margin of 2.0% or 2.25%, or
		(ii)	the prime rate, plus a margin of 0.25% or 0.50%.
	In each case, such margin is determined based on our adjusted quick ratio.
	The adjusted quick ratio is a ratio of our unrestricted cash and cash equivalents to our current liabilities minus the current portion of our deferred revenue. Interest on the revolving loans and the term loans is due and payable in arrears at the end of an interest period of 30, 60 or 90 days, as selected by us, for loans that bear interest based on the adjusted LIBOR rate, or quarterly for loans that bear interest based on the prime rate. Obligations under the loan facility are secured by a security interest on substantially all of our assets, excluding intellectual property.
	The Loan Agreement contains affirmative and negative covenants subject to certain exceptions. We must also comply with financial covenants under the Loan Agreement, including:
		(i)	a minimum quick ratio,
		(ii)	for the period from the closing through December 31, 2013, a minimum adjusted EBITDA; and
		(iii)	beginning with the fiscal quarter ending March 31, 2014, a minimum fixed charge coverage ratio and a maximum leverage ratio.
	On February 18, 2014, we entered into a Second Loan Modification Agreement with Silicon Valley Bank to modify the minimum adjusted EBITDA financial covenant for periods occurring after December 31, 2013. Additionally, the Second Loan Modification Agreement removed the fixed charge coverage ratio and maximum leverage ratio financial covenants, which were set to begin in periods occurring after December 31, 2013.
	The Loan Agreement also restricts our ability to pay dividends by requiring the written consent of Silicon Valley Bank to pay cash dividends to our stockholders.
	The Loan Agreement contains events of default including, among others, payment defaults, breaches of covenants, bankruptcy and insolvency events, cross defaults with certain material indebtedness, judgment defaults, and breaches of representations and warranties. Upon an event of default, all or a portion of the outstanding obligations may be declared to be immediately due and payable. During the existence of an event of default, interest on the obligations under the Loan Agreement could be increased by 5.0% per annum.
	At December 31, 2013, we had $1.0 million of outstanding letters of credit, no revolving loans outstanding under the Loan Agreement and $8.4 million of term loans outstanding at an interest rate of 2.24%. We were in compliance with all covenants as of December 31, 2013.

	In December 2011, our board of directors approved an increase of authorized common shares from 70,000,000 to 290,000,000. In accordance with Delaware state law, we cannot declare a dividend if it would cause an impairment of our capital, and it was determined that, at the time of the authorization, no impairment of our capital existed.
	In December 2011, in connection with our IPO, we issued 12,088,403 shares of our common stock at a price of $12.00 per share. In addition, all shares of outstanding preferred stock were converted into a total of 23,082,367 shares of our common stock upon our IPO.

	Stock Option Plans
	2011 Plan
	Our 2011 Equity Incentive Plan (the “2011 Plan”) replaced our 2007 Stock Incentive Plan (the “2007 Plan”) and our 2002 Equity Incentive Plan (the “2002 Plan”) upon completion of our IPO. Both the 2007 Plan and the 2002 Plan were then terminated. Awards that were outstanding upon termination of the 2007 Plan and the 2002 Plan remained outstanding pursuant to their original terms and awards subsequently terminated return to the pool of shares available for grant under the 2011 Plan.
	The 2011 Plan provides our board of directors broad discretion in creating employee equity incentives. Unless otherwise provided in the 2011 Plan document, the compensation committee in its discretion, determines the stock option exercise prices, which may not be less than the fair value of our common stock at the date of grant, vesting periods, and expiration periods, which are a maximum of ten years from the date of grant.
	The 2011 Plan allows for grants of incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares and performance units. Generally, all stock option grants are issued under an option agreement that provides, among other things, that the option grant vests over a four-year period while restricted stock units and performance stock unit agreements vest between 1 and four years.
	The number of shares available for issuance under the 2011 Plan will be increased on the first day of each year beginning with January 1, 2013, in an amount equal to the lesser of (i) 5,000,000 shares; (ii) 3.9% of the outstanding shares on the last day of the immediately preceding year; or (iii) such number of shares as determined by the board of directors.

	On January 1, 2014, an additional 2,720,200 shares were reserved for future awards under the 2011 Plan.
	Restricted Stock Activity
	Restricted stock results from the exercise of unvested restricted stock purchases (“RSPs”) and non-qualified stock options (“NSOs”) with reverse vesting provisions, and the grant of restricted stock awards (“RSAs”), PSUs, and RSUs. The shares of restricted stock vest over the period specified in the related RSP, NSO, RSA, PSU and RSU agreements. Restricted stock activity was as follows:
			Number			Weighted average

	Balances, December 31, 2013			4,796,112		$	15.24
	All shares to be issued upon the exercise of stock options and the vesting of RSUs and PSUs will come from newly issued shares.
	Stock-Based Compensation
	The fair value of the stock-based awards granted to employees was estimated using the Black-Scholes-Merton option-pricing model with the following weighted average assumptions:
			Year Ended December 31,
			2013			2012			2011
	Expected term (in years)			5.9			6.05			6.04
	Risk-free interest rate			1.09	%		1.01	%		1.79	%
	Volatility			52.17	%		54.47	%		55.2	%
	Dividend yield			0	%		0	%		0	%
	The expected terms of options granted were calculated using the simplified method, which defines the expected term as the average of the contractual term and the vesting period. We elected to use the simplified method due to a lack of term length data since we completed our initial public offering in December 2012 and our stock options meet the criteria of “plain-vanilla.” Estimated volatility incorporates a calculated volatility derived from the historical closing prices of common shares of our stock as well as similar entities whose share prices are publicly available for the expected term of the option. The risk-free interest rate is based on the U.S. Treasury constant maturities in effect at the time of grant for the expected term of the option. We use historical data to estimate the number of future stock option forfeitures.
	Prior to 2012, because there was no public market for our common stock prior to our IPO, our board of directors estimated the fair value of our common stock, for purposes of determining the exercise price of stock options and the fair value of restricted stock awards, based upon several factors, including, but not limited to, third-party valuations and our operating and financial performance.
	The third-party valuations took into consideration several factors, including, but not limited to:
		•		prices for preferred stock which were sold to outside investors in arms-length transactions, and the rights, preferences, and privileges of the preferred stock and the common stock;
		•		the fact that the option grants involved illiquid securities in a private company;
		•		our stage of development and revenue growth;
		•		the state of the industry and the economy;
		•		the marketplace and major competitors; and
		•		the likelihood of achieving a liquidity event for the shares of common stock underlying the options, such as an initial public offering or sale of our company, given prevailing market conditions.
	Certain information regarding our stock-based compensation was as follows (in thousands, except per share data):

Number of options granted			—			—			57,500
Stock-based compensation related to non-employee awards (included in total stock-based compensation above)		$	488		$	1,723		$	4,100
Vesting of shares granted to non-employees is contingent on the individual continuing to provide service. Expense for these awards was calculated using the Black-Scholes-Merton option-pricing model. These awards are equity classified and are marked to market each period with the change in fair value recorded in earnings. At December 31, 2013, there were no options exercisable for shares of our common stock by non-employees.
As of December 31, 2013, we had unrecognized compensation related to all stock-based awards of $92.7 million, which will be recognized over the weighted average remaining vesting period of 2.2 years.

	Included in the provision for (benefit from) income taxes for the years ended December 31, 2013, 2012 and 2011 is a $1.4 million, $0.3 million and $3.9 million tax benefit, respectively, from the release of valuation allowance on our deferred tax assets related to our acquisitions. In connection with the acquisitions of StreamOnce, Producteev and Meetings.io, a deferred tax liability was established for the book-tax basis differences related to the non-goodwill intangibles. The net deferred tax liability from these acquisitions creates an additional source of income to offset our deferred tax assets. The impact on our deferred tax assets and liabilities caused by the acquisitions is recorded outside of acquisition accounting.
	The reconciliation of the statutory federal income tax rate to the effective tax rate is as follows:

	Deferred Income Taxes
	Deferred income taxes reflect the net tax effects of (i) temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, and (ii) operating losses and tax credit carryforwards. The tax effects of significant items comprising our deferred tax assets and liabilities are as follows (in thousands):
		December 31,
		2013			2012
	Deferred tax assets:
	Net operating loss (“NOL”) carryforwards	$	61,568		$	45,954

	Depreciation and amortization		(6,756	)		(7,594	)
	Prepaid expenses		(146	)		(282	)
	Other		—			(9	)
	Total deferred tax liabilities		(6,902	)		(7,885	)
	Valuation allowance		(86,077	)		(53,385	)
	Net deferred taxes	$	(112	)	$	(6	)
	The tax benefit of net operating losses, temporary differences and credit carryforwards is recorded as an asset to the extent that we assess that realization is more likely than not. Realization of the future tax benefits is dependent on our ability to generate sufficient taxable income within the carryforward period. Due to our recent history of operating losses, we currently believe that the recognition of the deferred tax assets arising from the above mentioned future tax benefits is not more likely than not to be realized and, accordingly, have provided a full valuation allowance.
	Certain other information regarding our deferred income taxes was as follows (in thousands):
	(In thousands)	Year Ended December 31,
		2013			2012			2011
	Increase in valuation allowance	$	32,692		$	16,410		$	14,197
	(In millions)	December 31,
		2013			2012
	Federal and state NOL carryforwards	$	211.5		$	153.1
	Research and development tax credit carryforwards		7.8			3.6
	These carryforwards expire between 2014 and 2033.
Approximately $66.1 million of our NOL carryforwards at December 31, 2013 were generated as a result of excess tax deductions related to exercises of stock options and disqualifying dispositions. If utilized, this portion of our carryforwards, as tax effected, will be accounted for as a direct increase to contributed capital rather than as a reduction of that year’s provision for income taxes. NOL carryforwards created by excess tax benefits from the exercise of stock options are not recorded as deferred tax assets. Accordingly, the deferred tax assets related to the net operating losses were reduced by $28.0 million and $16.5 million at December 31, 2013 and 2012, respectively.
Unrecognized Tax Benefits
We recognize the effect of income tax positions only if those positions are more likely than not of being sustained. We recognize penalties and interest related to unrecognized tax benefits as a component of income tax expense. As of December 31, 2013 and 2012, there were no accrued penalties or interest recorded in the consolidated financial statements. All unrecognized tax benefits would currently not have an impact on the effective tax rate if recognized. The following is a reconciliation of our unrecognized tax benefits (in thousands):
	Year Ended December 31,
	2013			2012			2011
Beginning balance	$	737		$	660		$	380
Additions based on tax positions related to the current year		205			77			280
Additions based on prior year tax positions		151			—			—
Reductions for tax positions in prior years		(212	)		—			—
Settlements		(472	)		—			—
Ending balance	$	409		$	737		$	660
We are subject to income taxes in U.S. federal and various state, local and foreign jurisdictions. Generally, we are no longer subject to U.S. federal, state and local tax examinations for tax years ended before December 31, 2009. However, to the extent allowed by law, the tax authorities may have the right to examine prior periods where NOLs or tax credits were generated and carried forward, and make adjustments up to the amount of the NOL or credit carryforward. We recently completed a federal tax exam for the tax years ended December 31, 2010 and 2011. The examination did not have a significant impact on the financial statements. At December 31, 2013, we were not under exam in any other jurisdictions. There could be a significant impact to our uncertain tax positions over the next twelve months depending on the outcome of any audit. We do not anticipate that unrecognized tax benefits will decrease relating to expiring statutes of limitation by the end of 2014.
Unrepatriated Foreign Earnings
We did not repatriate any earnings of our foreign subsidiaries in 2013, 2012 or 2011. We plan to indefinitely reinvest the earnings of all of our foreign subsidiaries overseas. Should we plan to repatriate any foreign earnings in the future, we will be required to establish an income tax liability and recognize additional income tax expense related to such earnings. As of December 31, 2013, we had $1.6 million of unrepatriated cash held in foreign bank accounts.

	Legal Matters
	In October 2012, Bascom Research, LLC filed a complaint for patent infringement against us, among others, in the United States District Court for the Eastern District of Virginia, captioned Bascom Research, LLC v. Jive Software, Inc., Civil Case No. 1:12CV1114. In May 2013, we entered into a settlement and license agreement with Bascom. The cost of such settlement was consistent with amounts accrued for settlement and was not material to our business, financial condition, or results of operations.
	From time to time, we may become involved in routine litigation arising in the ordinary course of business. While the results of such litigation cannot be predicted with certainty, we believe that the final outcome of such matters will not have a material adverse effect on our financial position, results of operations or cash flows.
	Operating Leases
	Operating lease payments primarily relate to noncancelable operating leases associated with our offices in California, Oregon, Colorado, the United Kingdom, and Israel and data centers in Arizona, New Jersey and the Netherlands. The lease for our headquarters in Palo Alto, California expires in June 2020. The lease for the currently occupied space in Oregon expires in September 2018. The office leases in San Francisco, California and Boulder, Colorado expire in November 2015 and March 2016, respectively. The leases for the United Kingdom and Israeli offices expire in May 2018 and September 2017, respectively. The leases for our data centers in Arizona, New Jersey and the Netherlands expire in December 2016, September 2016 and October 2015, respectively.

	Accounting Pronouncements Not Yet Adopted
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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 amends the guidance related to the presentation of unrecognized tax benefits and allows for the reduction of a deferred tax asset for a net operating loss (“NOL”) carryforward whenever the NOL or tax credit carryforward would be available to reduce the additional taxable income or tax due if the tax position is disallowed. ASU 2013-11 is effective for annual and interim periods for fiscal years beginning after December 15, 2013, and early adoption is permitted. Since ASU 2013-11 relates only to the presentation of unrecognized tax benefits, the adoption of ASU 2013-11 in January 2014 did not have a material effect on our financial position, results of operations or cash flows.
	Recently Adopted Accounting Pronouncements
	In February 2013, the FASB issued ASU No. 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.” Under ASU 2013-02, an entity is required to provide information about the amounts reclassified out of Accumulated Other Comprehensive Income (“AOCI”) by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. ASU 2013-02 does not change the current requirements for reporting net income or other comprehensive income in the financial statements. We adopted ASU 2013-02 effective January 1, 2013. However, we did not have any reclassifications during 2013 that would require additional disclosure under this pronouncement.
	In July 2012, the FASB issued ASU 2012-02, “Intangibles – Goodwill and Other: Testing Indefinite-Lived Intangible Assets for Impairment,” which permits an entity to make a qualitative assessment to determine whether it is more likely than not that an indefinite-lived intangible asset, other than goodwill, is impaired. Entities are required to test indefinite-lived intangible assets for impairment at least annually and more frequently if indicators of impairment exist. If an entity concludes, based on an evaluation of all relevant qualitative factors, that it is not more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount, it is not required to perform the quantitative impairment test for that asset. Because the qualitative assessment is optional, an entity is permitted to bypass it for any indefinite-lived intangible asset in any period and apply the quantitative test. ASU 2012-02 also permits the entity to resume performing the qualitative assessment in any subsequent period. ASU 2012-02 is effective for impairment tests performed for fiscal years beginning after September 15, 2012 and early adoption is permitted. The adoption of ASU 2012-02 effective January 1, 2013 did not have any effect on our financial position, results of operations or cash flows.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States, or GAAP, requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the related disclosure of contingent assets and liabilities in the financial statements and the accompanying notes. Significant estimates include the estimates relating to revenue recognition, the useful lives of fixed assets, stock-based compensation, assumptions used in estimating the fair value of warrants, assumptions used in testing for impairment of goodwill and other long-lived assets, and the recoverability of deferred income tax assets and liabilities. Actual results could differ from those estimates, and such differences may be material to the consolidated financial statements.
Principles of Consolidation	'
	Principles of Consolidation
	The consolidated financial statements include the accounts of Jive Software, Inc. and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Reclassification	'
	Reclassification
	Certain prior year amounts have been reclassified to conform to current year presentation. These reclassifications were not significant to the financial statements.
Segments	'
	Segments
	An operating segment is defined as a component of an enterprise that meets the following criteria:
		•		engages in business activities from which it may earn revenues and incur expenses;
		•		operating results are regularly reviewed by the enterprise’s chief operating decision maker to make decisions about resources to be allocated to the segment and assess its performance; and
		•		discrete financial information is available.
	We define the term “chief operating decision maker” to be our Chief Executive Officer. Our Chief Executive Officer reviews financial information presented on a consolidated basis, accompanied by information about revenue by product line and geographic region for purposes of allocating resources and evaluating financial performance. We have one business activity and there are no segment managers who are held accountable for operations, operating results or plans for levels or components below the consolidated unit level. Accordingly, we have determined that we operate in a single reporting segment, software sales and service.
Revenue Recognition	'
	Revenue Recognition
	We generate revenues in the form of product fees and related professional service fees. Product fees include subscription fees, perpetual license fees, associated support and maintenance fees and hosting fees. Professional services primarily consist of fees for strategic consulting, configuration, training, consultation and implementation services, which are not essential to the functionality of the software. For statement of operations classification purposes, we allocate revenues to professional services based on the hourly rate billed for time and materials arrangements and based on the total fixed fee for fixed fee professional services. We recognize revenue when all of the following conditions are met:
		•		there is persuasive evidence of an arrangement;
		•		the product or services have been delivered to the customer;
		•		the amount of fees to be paid by the customer is fixed or determinable; and
		•		the collection of the related fees is reasonably assured.
	Signed agreements are used as evidence of an arrangement. If a contract signed by the customer does not exist, we have historically used a purchase order as evidence of an arrangement. In cases where both a signed contract and a purchase order exist, we consider the signed contract to be the final persuasive evidence of an arrangement. Software and corresponding license keys are delivered to customers electronically. Electronic delivery occurs when we provide the customer with access to the software. We assess whether a fee is fixed or determinable at the outset of the arrangement, primarily based on the payment terms associated with the transaction. We do not generally offer extended payment terms with typical terms of payment due between 30 and 60 days from delivery of solutions or services. For professional services that are billable under a time and materials based arrangement, these fees are neither fixed nor determinable until the work is performed and the fee becomes billable to the customer. We assess collectability of the customer receivable based on a number of factors such as collection history with the customer and creditworthiness of the customer. If we determine that collectability is not reasonably assured, revenue is deferred until collectability becomes reasonably assured, generally upon receipt of cash.
	We offer subscriptions of our platform to customers most frequently on a term basis with terms typically ranging from 12 to 36 months. While term-based licenses make up the majority of our total revenues, we occasionally license our solutions to customers on a perpetual basis with on-going support and maintenance services. We recognize license revenue in accordance with software industry specific guidance. Revenues related to term license fees are recognized ratably over the contract term beginning on the date the customer has access to the software license key and continuing through the end of the contract term. For term-based licenses, we do not charge separately for standard support and maintenance, and, therefore, inherent in the license fees are fees for support and maintenance services for the duration of the license term. As fees for support and maintenance are always bundled with the license over the entire term of the contract, we do not have vendor-specific objective evidence (“VSOE”) of fair value for support and maintenance. Revenues generated from perpetual license sales also include support and maintenance services for an initial stated term, both the perpetual license and support and maintenance are recognized ratably over the initial stated term. We do not have VSOE of fair value for support and maintenance on perpetual licenses as we have not had sufficient consistently priced standalone sales of support and maintenance, nor have we offered substantive renewal rates for support and maintenance. Additionally, customers who have purchased perpetual licenses to the base platform have historically also purchased term-based subscriptions to certain of our modules. We do not have VSOE of fair value for either the support and maintenance on the perpetual license or the module and, therefore, revenue is recognized ratably over the longer of the initial maintenance term for the perpetual license or the term for the subscription elements.
	License arrangements may also include professional services, such as strategic consulting installation, upgrades and training services, which are typically delivered early in the contract term. This combination of products and services represents a multiple-element arrangement for revenue recognition purposes. We have determined that we do not have VSOE of fair value for each element of a multiple-element sales arrangement and, accordingly, we account for fees received under that multiple-element arrangement as a single unit of accounting and recognize the fees for the entire arrangement ratably, commencing on delivery of the software, over the longer of the term of the support and maintenance or the period over which professional services are delivered. Support and maintenance is always the last undelivered element in the arrangement and, therefore, we recognize the fixed portion of the fees ratably over the support and maintenance term. For contracts with multiple elements, we recognize the license, support and maintenance, and fixed fee professional service revenue ratably over the term of the arrangement beginning upon delivery of the software. We believe this method most closely reflects the economics of the transaction as we deliver access to the software and we begin providing support and maintenance services as of the date the software is delivered.
	Professional services are offered on both fixed fee and time and materials hourly billing arrangements. For time and materials-based professional services that are part of a multiple-element arrangement where the fees for the professional services are not fixed or determinable upon delivery of the software, revenue is recognized ratably over the contract term as the related fees become fixed. These fees are not considered fixed at the outset of the arrangement and become fixed as the related work is performed and the fees are earned and billed. These services are typically provided early in the contract term with completion typically occurring in the first six months. As these fees become fixed, they are added to the total fee for the multiple-element arrangement and recognized ratably with all other arrangement fees over the entire contract term. When billed, a cumulative revenue catch-up is calculated as the revenue earned from the date the software was made available to the customer to the date services have been completed, with recognition continuing ratably to the end of the contract term. These amounts, when recognized in our Consolidated Statements of Operations, are classified as professional services revenues based on the hourly rates at which they are billed. If there are significant acceptance clauses associated with the license or services or uncertainty associated with our ability to perform the professional services, revenues are deferred until the acceptance is received or the uncertainty is resolved. We record amounts that have been invoiced, in accordance with the terms of the agreement, in accounts receivable and in deferred revenues or revenues, depending on whether the revenue recognition criteria have been met.
	Hosting revenues are derived from providing our software solutions in a hosted environment where the customer does not take possession of the software on their premises. With the exception of the Jive Cloud licensing model, customers have the option to elect to take possession of the software and install on their premises or sub-contract the hosting services through us. Such arrangements are considered software sales as the customer has the same rights to the software license regardless of their election to have us host on their behalf or install on their premises. As a result, the fees associated with license, support and hosted services are recognized as revenue ratably over the term of the arrangement. For Jive Cloud licensing arrangements, customers do not have the right to take possession of the software supporting the cloud-based application service at any time.
	We occasionally sell professional services separately and recognize revenues resulting from those as professional services are performed. If there is a significant uncertainty about the project completion or receipt of payment for the consulting services, revenues are deferred until the uncertainty is resolved. If acceptance provisions exist within a professional services arrangement, revenues will be deferred until the services are accepted, the acceptance period has expired or cash is received from the customer.
Taxes Collected from Customers and Remitted to Governmental Authorities	'
	Taxes Collected from Customers and Remitted to Governmental Authorities
	We account for tax assessed by a governmental authority that is directly imposed on a revenue-producing transaction (i.e., sales, use, value added) on a net (excluded from revenue) basis.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	We consider all highly liquid investments with an original maturity of three months or less to be cash equivalents. Our cash balances with financial institutions may exceed the deposit insurance limits. Included in cash and cash equivalents were cash equivalents of $6.7 million and $0.5 million at December 31, 2013 and 2012, respectively. Cash equivalents are stated at cost, which approximates market value.
Accounts Receivable and Allowance for Doubtful Accounts	'
	Accounts Receivable and Allowance for Doubtful Accounts
	Accounts receivable are carried at their original invoice amounts less the allowance for doubtful accounts and do not bear interest. Our policy is to maintain an allowance for estimated losses resulting from the inability or refusal of our customers to make required payments. In establishing the required allowance, management considers historical losses adjusted to take into account current market conditions and the customers’ financial condition, the amount of receivables in dispute, and the current receivables aging and current payment patterns. On a quarterly basis, we evaluate the collectability of our trade receivable balances based on a combination of factors. Past due balances over 90 days and over a specified amount are reviewed individually for collectability. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. If the financial conditions of our customers were to materially change or there were other circumstances that resulted in their inability or unwillingness to pay, the estimates of recoverability of receivables could materially change.
	Activity related to our allowance for doubtful accounts was as follows (in thousands):
	Balance, December 31, 2010		$	190
	Charges to costs and expenses			51
	Write-offs			(97	)

	Charges to costs and expenses			672
	Write-offs			(150	)
	Balance, December 31, 2013		$	740
Fair Value of Financial Assets and Liabilities	'
	Fair Value of Financial Assets and Liabilities
	The carrying value of cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable, accrued payroll and related liabilities and other accrued liabilities approximates their fair values due to the short-term nature of their maturities. The fair value of the long-term debt approximates its carrying value since the interest rate is variable and based on current market rates.
Property and Equipment	'
	Property and Equipment
	Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives as follows:
		•		three years for computer equipment, hardware and software;
		•		seven years for furniture, fixtures and equipment; and
		•		the lesser of five years or the remaining term of the underlying lease for leasehold improvements.
	Ordinary maintenance and repairs are expensed as incurred.
Research and Development	'
	Research and Development
	We expense research and development costs, including costs to develop software products to be marketed to external users, before technological feasibility of such products is reached. We believe our software development process is essentially completed concurrent with the establishment of technological feasibility; accordingly, development costs are expensed as incurred.
Internal-Use Software Development Costs	'
	Internal-Use Software Development Costs
	We capitalize costs to develop internal-use software during the application development stage. Costs related to preliminary project activities and post implementation activities are expensed as incurred. Capitalized software is included in property and equipment and is depreciated over the useful life when placed in service. Management evaluates the useful lives of these assets and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets.
	During 2013, we capitalized $3.1 million of such costs. Depreciation of these capitalized costs has not started as of December 31, 2013, as the related project is still in development. There were no internal-use software development costs capitalized in 2012 and 2011.
Accounting for the Impairment of Long-Lived Assets	'
	Accounting for the Impairment of Long-Lived Assets
	We evaluate the recoverability of our long-lived assets, which principally consist of property and equipment and acquired intangible assets with finite lives, whenever events or circumstances indicate that the carrying amount of these assets may not be recoverable. Recoverability of an asset is measured by comparing the carrying amount to the expected future undiscounted cash flows that the asset is expected to generate. If that review indicates that the carrying amount of the long-lived asset is not recoverable, an impairment loss is recorded for the amount by which the carrying amount of the asset exceeds its fair value.
	We did not incur any long-lived asset impairment charges in the years ended December 31, 2013, 2012 or 2011.
Goodwill	'
	Goodwill
	Goodwill represents the excess of the purchase price over the estimated fair value of the net tangible and intangible assets of acquired entities. We perform a goodwill impairment test annually during the fourth quarter of our fiscal year and more frequently if an event or circumstance indicates that an impairment may have occurred. Such events or circumstances may include significant adverse changes in the general business climate, among other things.
	Beginning in 2012, we are allowed to first make a qualitative assessment to determine whether it is more likely than not that goodwill is impaired before applying the two-step goodwill impairment test. If the conclusion is that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we then perform a two-step goodwill impairment test. During 2013 and 2012, we elected to forgo the qualitative assessment, and proceeded to the first step of the test for goodwill impairment. Under the first step, the fair value of the reporting unit is compared with its carrying value, and, if an indication of goodwill impairment exists for the reporting unit, we must perform step two of the impairment test (measurement). Under step two, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill as determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation. The residual fair value after this allocation is the implied fair value of the reporting unit goodwill. If the fair value of the reporting unit exceeds its carrying value, step two does not need to be performed. If the carrying amount of goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. We did not record any charges related to goodwill impairment during the years ended December 31, 2013, 2012 or 2011.
Intangible Assets	'
	Intangible Assets
	Definite-lived intangible assets are amortized using the straight-line method over estimated useful lives and have no significant residual value. Definite-lived intangible assets are reviewed for impairment as discussed above under “Accounting for the Impairment of Long-Lived Assets.”
Other Assets	'
	Other Assets
	Other assets include deposits for facilities leases and other miscellaneous long-term assets.
Deferred Revenue	'
	Deferred Revenue
	Deferred revenue consists of billings or payments received in advance of revenue recognition from our subscription license, perpetual license, hosting, professional services and support and maintenance revenues described above and are recognized as the revenue recognition criteria are met. We generally invoice our customers in annual installments. Accordingly, the deferred revenues balance does not represent the total contract value of annual or multi-year non-cancelable subscription agreements. Deferred revenue also includes certain deferred professional services fees, which are recognized as revenues ratably over the associated contract term. We defer the professional service fees in situations where the professional services and subscription or perpetual contracts are accounted for as a single unit of accounting. Deferred revenue that will be recognized during the succeeding 12-month period is recorded as current deferred revenue, and the remaining portion is recorded as noncurrent. Approximately 4% and 5% of total deferred revenue as of December 31, 2013 and 2012, respectively, related to deferred professional services revenues.
Concentration of Risk	'
	Concentration of Risk
	Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and trade receivables. Cash is placed on deposit in major financial institutions in the United States. Such deposits may be in excess of insured limits. Management believes that the financial institutions that hold our cash deposits are financially sound and, accordingly, minimal credit risk exists with respect to these balances.
	We sell our products to companies in diverse industries and do not require our customers to provide collateral to support accounts receivable. When necessary, credit reviews of significant customers are performed prior to extending credit. The determination of a customer’s ability to pay requires significant judgment, and failure to collect from a customer can adversely affect revenues, cash and net income.
	No individual customer accounted for 10% or more of total revenues in the years ended December 31, 2013, 2012 or 2011. One customer accounted for 14% of accounts receivable at December 31, 2013. No customer accounted for 10% or more of total accounts receivable at December 31, 2012.
Stock-Based Compensation	'
	Stock-Based Compensation
	We recognize compensation expense for all share-based payment awards, including stock options and restricted stock, based on the estimated fair value of the award on the grant date. We use the Black-Scholes-Merton valuation model to estimate the fair value of stock option awards. The fair value of the awards is recognized as expense, net of estimated forfeitures, over the requisite service period, which is generally the vesting period of the respective award.
	Stock-based compensation expense is recognized for performance-based restricted stock awards based on the probability of achieving certain performance criteria. We estimate the number of performance-based restricted stock awards ultimately expected to vest and recognize expense using the graded vesting attribution method over the requisite service period.
	The determination of the grant date fair value of options using an option-pricing model is affected by assumptions regarding a number of other complex and subjective variables, which include our expected stock price volatility over the expected term of the options, stock option exercise and cancellation behaviors, risk-free interest rates and expected dividends. In addition, prior to our initial public offering (“IPO”) in December 2011, we also made assumptions regarding the fair value of our common stock.
Income Taxes	'
	Income Taxes
	We record deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement carrying amounts and the tax basis of the assets and liabilities. Deferred tax assets are reduced by a valuation allowance when it is estimated to be more likely than not that a portion of the deferred tax assets will not be realized.
	We recognize the effect of income tax positions only if those positions are “more likely than not” of being sustained. Interest and penalties accrued on unrecognized tax benefits are recorded as tax expense within our consolidated financial statements.
Warranties	'
	Warranties
	We typically warrant that our products will perform in a manner consistent with the product specifications provided to the customer for 180 days for sales to companies in the United States and 365 days for sales to companies in Europe. Historically, we have not been required to make payments under these obligations, and we have not recorded any liability for these obligations in our consolidated financial statements.
Commissions	'
	Commissions
	Commissions are recorded as a component of sales and marketing expenses and consist of the variable compensation paid to our direct sales force. Generally, sales commissions are earned and recorded as an expense at the time that a customer has entered into a binding purchase agreement. Commissions paid to sales personnel are recoverable only in the case that we cannot collect against any invoiced fee associated with a sales order. Commission expense was $15.7 million, $12.9 million and $9.2 million, for the years ended December 31, 2013, 2012 and 2011, respectively.
Leases	'
	Leases
	We lease our facilities under operating leases. For leases that contain rent escalation or rent concession provisions, we record the total rent expense during the lease term on a straight-line basis over the term of the lease. We record the difference between the rent paid and the straight-line rent expense as a deferred rent liability in other long-term liabilities in the accompanying Consolidated Balance Sheets.
Advertising Costs	'
	Advertising Costs
	Advertising costs are expensed as incurred as a component of sales and marketing expense and totaled $5.3 million, $4.9 million and $2.2 million for the years ended December 31, 2013, 2012 and 2011, respectively.
Legal Costs	'
	Legal Costs
	We are a party to legal proceedings arising in the normal course of business. Legal costs are expensed as incurred as a component of general and administrative expense.
Net Loss Per Share	'
	Net Loss Per Share
	Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period, less the weighted-average unvested common stock subject to repurchase or forfeiture. Diluted net loss per share is computed by giving effect to all potential shares of common stock, including preferred stock, stock options and warrants, to the extent dilutive. Since we were in a loss position for all periods presented, basic and diluted net loss per share was the same for each period presented as the inclusion of all potential common shares outstanding would have been anti-dilutive.
Foreign Currency Translation	'
	Foreign Currency Translation
	The functional currency of our foreign subsidiaries is the local currency. Adjustments resulting from translating foreign functional currency financial statements into U.S. dollars are recorded as a separate component of stockholders’ deficit. Income and expense accounts are translated into U.S. dollars at average rates of exchange prevailing during the periods presented. Foreign currency transaction gains and losses are included in net loss. All assets and liabilities denominated in a foreign currency are translated into U.S. dollars at the respective exchange rates in effect on the consolidated balance sheet dates. Foreign currency transaction gains and losses were not material in the years ended December 31, 2013, 2012 or 2011.
