Dropbox Agrees to Pay $350 Million for Tigris Data, $120 Million Above Its Previous Record

Dropbox agreed to buy Tigris Data for about $350 million in cash, $120 million more than it paid for HelloSign, its previous largest deal, the company said Thursday.

The purchase is announced, not closed. Dropbox's Form 8-K says the definitive agreement was signed Nov. 3 and that closing is expected in the fourth quarter of 2026, subject to customary conditions and purchase price adjustments it does not describe. The press release filed with it carries no price at all and warns that the deal may not close on time or at all.

What $350 million buys

Tigris is a Sunnyvale company founded in 2021 by former Uber engineers. It sells S3-compatible object storage, meaning storage that speaks Amazon's S3 interface, which the release says lets developers keep data across clouds without lock-in or egress fees. Crunchbase News counts about $31.9 million raised in total, including a $25 million Series A in October 2025 led by Spark Capital with Andreessen Horowitz and Basis Set Ventures taking part.

That makes the price roughly 11 times the capital Tigris disclosed raising. The multiple is against funding, not revenue: neither Dropbox nor Tigris has published Tigris revenue, so there is no way to say what the company is being valued on. Chief Executive Ovais Tariq told TechCrunch at the Series A that Tigris had grown 8x every year since founding, according to Crunchbase's account, and that is a single-source claim with no base figure attached.

DBX Agent Cloud launches with one product

Dropbox introduced DBX Agent Cloud alongside the deal. It starts as standalone S3-compatible object storage that works with tools built for Amazon S3, and the release says filesystem and content-processing features come next, with no dates. Eric Webster, Dropbox's chief business officer, told Crunchbase that Tigris brings "a product already running in production" and that Agent Cloud "opens a new developer and infrastructure market for Dropbox."

Co-Chief Executive Ashraf Alkarmi framed the other half of the strategy in the release: "The value of AI depends on the content and context it can work with." The AI features inside Dropbox's file product have reached more than 70,000 teams, limited so far to eligible Standard and Advanced teams in the US, UK and Australia, in English. Broader availability is planned for 2027.

Developers who want S3-style storage for local testing already have free options, such as Floci, the MIT-licensed LocalStack alternative covered earlier. Paid object storage with no egress fees is the part Tigris sells.

A slower buyer, one larger deal

Period	Dropbox acquisitions (Crunchbase count)
2012 to 2015	23, including nine in 2014
2024	2 (Reclaim.ai, Nira)
2025	2 (Promoted.ai, Mobius Labs)

Crunchbase counts 35 known Dropbox acquisitions, so the 2024 and 2025 pace of about two a year is roughly 65 percent below the early years. The earlier large deals were all in collaboration software: HelloSign at $230 million in 2019, DocSend at $165 million in 2021 and FormSwift at $95 million in 2022. Tigris is the first of them aimed at selling infrastructure to other builders. Exits of this size also feed the fund-raising cycle that Sequoia described in its memo announcing about $10 billion in funds.

The date to watch is Dec. 31, the end of the quarter in which Dropbox says it expects to close. The 8-K does not disclose a termination fee, so a failed close would be visible only through a later filing.
