Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Non-cancelable Material Commitments During the nine months ended October 31, 2024, other than certain non-cancelable operating leases described in Note 6, Leases, there have been no material changes outside the ordinary course of business to the Company’s contractual obligations and commitments from those disclosed in the 2024 Form 10-K. Legal Matters The Company investigates all claims, litigation and other legal matters as they arise. From time to time, the Company has become involved in claims, litigation and other legal matters arising in the ordinary course of business, including intellectual property, labor and employment and breach of contract claims. For example, on July 9, 2024, a putative class action lawsuit, captioned Baxter v. MongoDB, Inc., et al., was filed in the United States District Court for the Southern District of New York against MongoDB, CEO Dev Ittycheria, and COO and CFO Michael Gordon. The lawsuit asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act, and alleges that defendants made material misstatements and/or omissions, including regarding MongoDB’s sales strategy and its financial results. The complaint is purportedly brought on behalf of a putative class of persons who purchased or otherwise acquired MongoDB common stock between August 31, 2023 and May 30, 2024. It seeks unspecified monetary damages, costs and attorneys’ fees, and other unspecified relief. The Company is unable to estimate any reasonably possible loss, or range of loss, with respect to these matters at this time. The Company intends to vigorously defend themself in this matter. On October 7, 2024, a shareholder derivative action was filed by Anand Roy, on behalf of the Company, in the U.S. District Court for the Southern District of New York, Case. No. 1:24-cv-07594, against the Company (as a nominal defendant), and certain officers and directors. This derivative action alleges the same core allegations as stated in the securities class action lawsuit. Similar cases were subsequently filed in the same district (together with the Roy matter, the “Derivative Litigations”). The Derivative Litigations are at an early stage; the Roy matter has been stayed, pending the outcome of the Court's decision on the defendants’ anticipated motion to dismiss the securities class action lawsuit, and defendants have not yet been served in the other Derivative Litigations. The Company is unable to estimate any reasonably possible loss, or range of loss, with respect to these matters at this time. Although claims and litigation are inherently unpredictable, as of October 31, 2024, other than as disclosed above, the Company is currently not aware of any matters that, if determined adversely to the Company, would individually or taken together have a material adverse effect on its business, financial position, results of operations or cash flows. The Company accrues estimates for resolution of legal and other contingencies when losses are probable and estimable. Regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources and other factors. Indemnification The Company enters into indemnification provisions under its agreements with other companies in the ordinary course of business, including business partners, landlords, contractors and parties performing its research and development. Pursuant to these arrangements, the Company agrees to indemnify, hold harmless and reimburse the indemnified party for certain losses suffered or incurred by the indemnified party as a result of the Company’s activities. The terms of these indemnification agreements are generally perpetual. The maximum potential amount of future payments the Company could be required to make under these agreements is not determinable. To date, the Company has not incurred material costs as a result of such commitments. The Company maintains commercial general liability insurance and product liability insurance to offset certain of the Company’s potential liabilities under these indemnification provisions. The Company has entered into indemnification agreements with each of its directors and executive officers. These agreements require the Company to indemnify such individuals, to the fullest extent permitted by Delaware law, for certain liabilities to which they may become subject as a result of their affiliation with the Company.
