Dropbox to buy Tigris Data for about $350 million and launch DBX Agent Cloud storage

What Dropbox agreed to buy

Dropbox said on 5 November 2026 that it plans to acquire Tigris Data, the developer of a globally distributed object storage platform built for AI workloads. A Form 8-K filed with the SEC shows that the merger agreement was signed on 3 November and sets the price at approximately $350 million in cash, subject to customary purchase price adjustments. The filing says closing is expected in the fourth quarter of 2026, once customary closing conditions are met or waived.

Tigris sells storage that speaks the Amazon S3 API, so applications written for S3 can point at it without code changes, and it spreads data across regions and clouds. Its founders are former Uber engineers who built the ride-hailing company's storage infrastructure, according to TechCrunch, and co-founder Ovais Tariq is chief executive. In a post on the Tigris blog, the company says its product, its S3-compatible API and its pricing without egress fees will stay the same after the deal. Tariq said Dropbox brings nearly two decades of experience operating storage at scale, which, combined with the Tigris product and its developer relationships, would help the service take on larger workloads.

DBX Agent Cloud, a storage product for AI builders

Alongside the deal, Dropbox announced DBX Agent Cloud, a storage platform aimed at businesses and developers building AI models and agents, rather than at the people who sync files through the Dropbox apps. The company says it will start with standalone, S3-compatible object storage based on the Tigris technology. Dropbox plans to add filesystem features later, so that AI agents can manage files and keep continuity across tasks and sessions, along with content processing on top of the stored data.

Object storage is where AI teams keep the bulk of their data: training sets, model weights and checkpoints, embeddings, logs and the documents and media that agents fetch while they work. Most of that sits today with Amazon Web Services, Google Cloud and Microsoft Azure, which charge customers for moving data out of their networks. Tigris built its pitch on removing that egress charge and on letting customers store and read the same data across regions and clouds, which matters to companies that rent compute from several providers. DBX Agent Cloud takes that pitch to a larger company with an existing enterprise sales force.

Dropbox has not published a price or a general availability date for DBX Agent Cloud, and the announcement does not say whether existing Tigris customers will be moved onto the Dropbox brand. Those details are not stated in the announcement.

Why a file sync company wants AI storage

ITPro calls the purchase the largest acquisition in Dropbox's history, and TechCrunch says it appears to be. It comes as growth in the core business has slowed to almost nothing. The company's third quarter results, released the same day, show revenue of $637.3 million, up 0.5% year over year, or 1.0% excluding FormSwift, a product it is winding down. Paying users reached 18.20 million, with average revenue per paying user of $138.76.

Dropbox has deep storage experience of its own: as The New Stack points out, it moved most of its data off Amazon S3 years ago onto an in-house system. Selling S3-compatible storage back to developers turns that operating experience into a new product line in a market where demand is driven by training data, model checkpoints and the files that agents read and write. The bet is also a bet against the large clouds' egress fees, which Tigris has made a selling point. Our reading: for Dropbox the deal is cheap compared with the AI infrastructure deals of recent weeks, such as Marvell's agreement to buy Lumentum, but it is a clear change of direction for a company built around consumer and small team file sync.

What to watch next

The first milestone is the closing, which Dropbox expects before the end of 2026. After that, the open questions are pricing, regions and when DBX Agent Cloud becomes generally available, whether the filesystem and processing features ship in 2027, and whether Dropbox keeps the Tigris brand for developers. Investors will also look for the first revenue figure from the new line in Dropbox's results. The deal joins a run of AI infrastructure acquisitions tracked in our AI funding tracker, including OpenAI's purchase of Pierre Computer for code storage behind Codex. More company news is on the AI business page.

For Tigris, the price is a large multiple of the money it raised: FourWeekMBA notes that $350 million is 14 times the startup's $25 million Series A, a comparison that says nothing about its revenue, which neither company has disclosed. For developers already storing data on Tigris, the practical promise for now is continuity, since the company says the API and the pricing model stay as they are.
