Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Non-cancelable Material Commitments During the three months ended April 30, 2026, other than certain non-cancelable operating leases described in Note 5, 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 2026 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. (Case No. 1:24-cv-5191), was filed in the United States District Court for the Southern District of New York against MongoDB, former CEO Dev Ittycheria, and former COO and CFO Michael Gordon (the “Securities Action”). On January 27, 2025, the lead plaintiff in the lawsuit the Securities Action filed an Amended Complaint naming former Senior Vice President of Finance and former Interim CFO Srdjan Tanjga as an additional defendant. The operative complaint 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, growth projections 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 June 1, 2023 and May 30, 2024. It seeks unspecified monetary damages, costs and attorneys’ fees, and other unspecified relief. Defendants filed a motion to dismiss the complaint on May 9, 2025. Plaintiffs filed an opposition brief on July 1, 2025, and defendants filed their reply brief on July 29, 2025. On May 1, 2026, the Court entered an order granting Defendants’ motion to dismiss in part and denying it in part, as it relates to four specific statements. On May 15, 2026, Defendants filed a motion for reconsideration of the Court’s order on the motion to dismiss. 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 itself in this matter. On October 7, 2024, a purported shareholder derivative lawsuit was filed in the U.S. District Court for the Southern District of New York, captioned Roy v. Ittycheria et al. (Case. No. 1:24-cv-07594), against the Company, as a nominal defendant, and former CEO Dev Ittycheria, former COO and CFO Michael Gordon, and several of the Company’s current and former directors. The lawsuit alleges that the individual defendants breached their fiduciary duties and committed other alleged misconduct in connection with the statements at issue in the Securities Action and by causing the Company to issue allegedly false and misleading statements to investors. Another similar case, Silva v. Ittycheria et al. (Case No. 1:24-cv-9014) was subsequently filed in the same district on November 25, 2024 against MongoDB, as nominal defendant, and the same individual defendants as the Roy S.D.N.Y. action. It has been consolidated with the Roy action with the caption In re MongoDB, Inc. Shareholder Litigation (Case No. 1:24-cv-9014) (the “S.D.N.Y. Derivative Litigation”). On September 12, 2025 another purported derivative action was filed in the Court of Chancery of the State of Delaware (Case No. 2025-1030) (the “Delaware Derivative Litigation”), against the Company, as a nominal defendant, and former CEO Dev Ittycheria, former COO and CFO Michael Gordon, and several of the Company’s current and former directors. The case is captioned Sansone v. Ittycheria, et al. The lawsuit, like the S.D.N.Y. Derivative Litigation, alleges that the individual defendants breached their fiduciary duties and committed other alleged misconduct in connection with the statements at issue in the Securities Action and by causing the Company to issue allegedly false and misleading statements to investors. The S.D.N.Y. Derivative Litigation and the Delaware Derivative Litigation have been stayed pending the outcome of the Court’s decision on the defendants’ motion for reconsideration in the Securities Action. Although claims and litigation are inherently unpredictable, as of April 30, 2026, 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.
