Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Basis of Presentation and Consolidation	Note 1. Description of Business and Basis of Presentation and Consolidation Description of Business Rapid7, Inc. and subsidiaries is a leading provider of security data and analytics solutions that enable organizations to implement an active, analytics-driven approach to cyber security. Our solutions empower organizations to prevent attacks by providing visibility into vulnerabilities and to rapidly detect compromises, respond to breaches and correct the underlying causes of attacks. Basis of Presentation and Consolidation The accompanying unaudited consolidated financial statements have been prepared by us in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) as well as pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. Accordingly, certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. These consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in our final prospectus for our initial public offering (IPO) dated as of July 16, 2015 and filed with the SEC pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended. The consolidated financial statements include our results of operations and those of our wholly-owned subsidiaries and reflect all adjustments (consisting solely of normal, recurring adjustments) which are, in the opinion of management, necessary for a fair statement of results for the interim periods presented. All intercompany transactions and balances have been eliminated in consolidation. The results of operations for the three and six months ended June 30, 2015 are not necessarily indicative of the results to be expected for any future period or the entire fiscal year. Unaudited Pro Forma Balance Sheet as of June 30, 2015 On July 22, 2015, we closed our IPO in which we sold and issued 7,417,500 shares of common stock (see note 10). Upon closing of the IPO, all of the redeemable convertible preferred stock outstanding automatically converted into 18,322,605 shares of common stock, which included 1,939,990 of additional shares of common stock issued upon conversion of our Series D preferred stock (Series D IPO Participation Payment). In addition, concurrently with the closing of our IPO, we issued 312,500 shares of common stock to entities affiliated with Technology Crossover Ventures in a private placement, for net proceeds of $5.0 million. The pro forma stockholders’ equity, as set forth on the pro forma June 30, 2015 consolidated balance sheet, has been adjusted to reflect the assumed: (i) conversion of our preferred stock into common stock and related beneficial conversion charge of $14.2 million associated with the Series D IPO Participation Payment, (ii) the sale and issuance of 7,417,500 shares of common stock and the receipt of net proceeds upon the closing of the IPO and (iii) the sale and issuance of 312,500 shares of common stock and the receipt of the net proceeds upon the closing of the private placement issuance. The unaudited pro forma net loss per share for the three and six months ended June 30, 2015 assumes: (i) the conversion of all outstanding shares of redeemable convertible preferred stock into an aggregate of 18,322,605 shares of common stock as of January 1, 2015, (ii) the sale and issuance of 7,417,500 shares of common stock upon the closing of the IPO as of January 1, 2015 and (iii) the sale and issuance of 312,500 shares of common stock to entities affiliated with Technology Crossover Ventures in a the private placement as of January 1, 2015. The amount recorded to reflect the beneficial conversion charge as a result of the Series D IPO Participation Payment has been included and the amounts recorded to reflect the accretion of preferred stock to redemption value on the redeemable convertible preferred stock have been added back to arrive at pro forma net loss attributable to common stockholders and pro forma net loss per share attributable to common stockholders. We believe that the unaudited pro forma balance sheet, pro forma net loss attributable to common stockholders and pro forma net loss per share attributable to common stockholders provides meaningful information to investors, such as measures of equity, net loss and net loss per share that are comparable to what will be reported by us in our consolidated financial statements for the periods subsequent to and including July 22, 2015.

Business Combinations [Abstract]
Business Combinations	Note 2. Business Combinations On April 30, 2015, we acquired 100% of the outstanding equity of NT OBJECTives, Inc. (NTO). We acquired NTO to expand our web application security offerings. We acquired NTO for total consideration of $6.0 million. We made an initial payment of $3.4 million in cash and issued $0.1 million (9,091 shares) of our common stock upon the closing of the acquisition and are obligated to make two additional payments of $1.5 million each, less the amount of any indemnity claims and net working capital adjustments, on the first and second anniversary dates of the closing. The net present value of these two additional payments, or $2.5 million, is included in the total purchase consideration paid. We expensed the related acquisition costs of $0.4 million in general and administrative expense. The following table summarizes the consideration paid for NTO and the preliminary allocation of purchase price to the estimated fair value of the assets acquired and liabilities assumed at the acquisition date: Consideration (in thousands): Cash $ 3,404 Stock consideration 99 Net present value of deferred cash payments 2,496 Fair value of total consideration transferred $ 5,999 Recognized amounts of identifiable assets acquired and liabilities assumed (in thousands): Net working capital $ (584 ) Intangible assets 2,090 Total identifiable net assets assumed 1,506 Goodwill 4,493 Net purchase price $ 5,999 The fair values of identifiable intangible assets were based on valuations using the income approach. The estimated fair values and useful lives of the identifiable intangible assets are as follows: Amount Weighted-average life (in thousands) (years) Developed technology $ 1,950 6 Customer relationships 100 4 Non-compete agreements 40 2 Identifiable intangible assets $ 2,090 The excess of the purchase price over the tangible assets, identifiable intangible assets and assumed liabilities was recorded as goodwill. We believe the amount of goodwill is the expected synergistic benefits of being able to leverage the integration of our existing products and services with the acquired products to both NTO and our customer bases. The goodwill was allocated to our one reportable segment. The acquired goodwill and intangible assets will not be deductible for tax purposes. These preliminary amounts are subject to subsequent adjustment as we obtain additional information to finalize certain components of working capital. Revenues for NTO were immaterial and the net loss for NTO was $1.2 million from the acquisition date through June 30, 2015. Pro forma results of operations have not been included, as the acquisition of NTO was not material to our results of operations for any periods presented. In May 2015, we entered into loan agreements with certain retained employees of NTO. The terms of these agreements require the employees to pay us the total amount borrowed, with accrued interest at 1.7% per annum, within 18 months of the agreement date. The loan agreements are secured by restricted stock awards granted to the employees. The aggregate amount of these loans was $0.5 million and is classified as other assets on the consolidated balance sheet.

Upon the closing of the IPO, all of our outstanding preferred stock automatically converted into 18,322,605 shares of common stock, which included 1,939,990 additional shares of common stock issued upon conversion of our Series D preferred stock. On July 22, 2015, concurrently with the closing of our IPO, we issued and sold to entities affiliated with Technology Crossover Ventures 312,500 shares of our common stock in a private placement at a price equal to the IPO price of $16.00 per share, resulting in net proceeds to us of $5.0 million. Additionally, in connection with the closing of our IPO, we filed an amended and restated certificate of incorporation with the Secretary of State of the State of Delaware that amended and restated in its entirety our certificate of incorporation to, among other things (i) increase the total number of shares of our common stock that we are authorized to issue to 100,000,000 and (ii) eliminate all references to the various series of preferred stock that were previously authorized (including certain protective measures held by the various series of preferred stock), except for the reference to 10,000,000 shares of undesignated preferred stock that may be issued, and with terms to be set, by our board of directors. On July 23, 2015, we repaid our term loan with Silicon Valley Bank. The aggregate amount paid was $18.7 million, which included the full principal amount of $18.0 million, the termination payment of $0.5 million and $0.2 million of accrued interest. Upon the repayment and termination of the term loan, we recorded a $0.9 million charge to interest expense for the unamortized portion of the debt discount. On August 5, 2015, we also terminated our line of credit with Silicon Valley Bank, under which there was no outstanding balance. On August 17, 2015, we entered into an amendment to our lease agreement for our principal executive offices in Boston, Massachusetts for approximately 20,000 additional square feet. We expect to occupy the additional office space in March 2016 and the term of the lease is 42 months.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying unaudited consolidated financial statements have been prepared by us in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) as well as pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. Accordingly, certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. These consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in our final prospectus for our initial public offering (IPO) dated as of July 16, 2015 and filed with the SEC pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended. The consolidated financial statements include our results of operations and those of our wholly-owned subsidiaries and reflect all adjustments (consisting solely of normal, recurring adjustments) which are, in the opinion of management, necessary for a fair statement of results for the interim periods presented. All intercompany transactions and balances have been eliminated in consolidation. The results of operations for the three and six months ended June 30, 2015 are not necessarily indicative of the results to be expected for any future period or the entire fiscal year. Unaudited Pro Forma Balance Sheet as of June 30, 2015 On July 22, 2015, we closed our IPO in which we sold and issued 7,417,500 shares of common stock (see note 10). Upon closing of the IPO, all of the redeemable convertible preferred stock outstanding automatically converted into 18,322,605 shares of common stock, which included 1,939,990 of additional shares of common stock issued upon conversion of our Series D preferred stock (Series D IPO Participation Payment). In addition, concurrently with the closing of our IPO, we issued 312,500 shares of common stock to entities affiliated with Technology Crossover Ventures in a private placement, for net proceeds of $5.0 million. The pro forma stockholders’ equity, as set forth on the pro forma June 30, 2015 consolidated balance sheet, has been adjusted to reflect the assumed: (i) conversion of our preferred stock into common stock and related beneficial conversion charge of $14.2 million associated with the Series D IPO Participation Payment, (ii) the sale and issuance of 7,417,500 shares of common stock and the receipt of net proceeds upon the closing of the IPO and (iii) the sale and issuance of 312,500 shares of common stock and the receipt of the net proceeds upon the closing of the private placement issuance. The unaudited pro forma net loss per share for the three and six months ended June 30, 2015 assumes: (i) the conversion of all outstanding shares of redeemable convertible preferred stock into an aggregate of 18,322,605 shares of common stock as of January 1, 2015, (ii) the sale and issuance of 7,417,500 shares of common stock upon the closing of the IPO as of January 1, 2015 and (iii) the sale and issuance of 312,500 shares of common stock to entities affiliated with Technology Crossover Ventures in a the private placement as of January 1, 2015. The amount recorded to reflect the beneficial conversion charge as a result of the Series D IPO Participation Payment has been included and the amounts recorded to reflect the accretion of preferred stock to redemption value on the redeemable convertible preferred stock have been added back to arrive at pro forma net loss attributable to common stockholders and pro forma net loss per share attributable to common stockholders. We believe that the unaudited pro forma balance sheet, pro forma net loss attributable to common stockholders and pro forma net loss per share attributable to common stockholders provides meaningful information to investors, such as measures of equity, net loss and net loss per share that are comparable to what will be reported by us in our consolidated financial statements for the periods subsequent to and including July 22, 2015.
