Dropbox is buying Tigris Data, an S3-compatible object storage platform built for AI workloads, for about $350 million in cash, in what appears to be the company’s largest acquisition to date. The deal, announced on Thursday, is expected to close in the fourth quarter of 2026. Alongside it, Dropbox is launching DBX Agent Cloud, a storage and data layer for companies building AI models and agents.
Storage built for agents
DBX Agent Cloud will start with standalone object storage that works with existing tools built for Amazon S3, letting businesses buy storage on its own. Dropbox plans to add filesystem features so agents can manage files and keep continuity across tasks and sessions, and to extend the platform to documents, images, audio and video.
Tigris was founded by former Uber engineers who built the ride-hailing company’s storage infrastructure, and it raised a $25 million Series A last year. Its platform positions data closer to the users and computing resources that need it, cutting access times. Dropbox says it has no plans to cut jobs as part of the acquisition.
Tigris’s edge is speed. Its platform automatically positions data closer to the users and computing resources that need it, which matters when agents fetch files constantly. For AI workloads, where a model may pull the same datasets again and again, that positioning is the difference between a snappy agent and a slow one.
AI across the product
Dropbox is also bringing more AI into its core product. Users will be able to ask AI to perform supported tasks using their files, choose between different AI models, and connect their Dropbox content to third-party tools including ChatGPT, Claude and Muse. The updated experience has already reached more than 70,000 teams, with wider availability planned for 2027.
The updated experience is already live for eligible Standard and Advanced customers in the US, UK and Australia, with broader availability planned for 2027. That rollout matters because Dropbox’s AI features only work if they reach the teams that already store their files there.
The acquisition is Dropbox’s latest move into AI through dealmaking, after earlier purchases of Reclaim.ai, Promoted.ai and Mobius Labs. The company cut 9 percent of its global workforce last month, according to the Wall Street Journal, and the Tigris deal is a clear statement that its future bets are on AI infrastructure rather than headcount.
Our read
Dropbox has spent years as a file sync company looking for a second act, and AI infrastructure is a credible one. Storage is the unglamorous layer every agent needs: models and agents are only useful if they can reach the right files quickly and keep track of them.
Buying Tigris gives Dropbox that layer, and DBX Agent Cloud gives it a product to sell around it. The question is whether customers will buy storage from Dropbox rather than from the cloud giants that already host their data today.
The comparison with rivals is instructive. Mistral just turned Studio into an agent factory, and every major lab is building agent platforms; all of them need storage that understands agents. Dropbox is betting that the storage layer is a business of its own, not just a feature inside someone else’s platform.
Why It Matters
AI agents are moving from demos to real work, and real work needs files: contracts, images, datasets, records that persist across sessions. Whoever owns the storage layer for agents owns a toll booth on that work. Dropbox’s $350 million bet is that a storage company can become an AI infrastructure company.
Background
The AI infrastructure buildout has been one of the year’s biggest stories, from new data centre capacity in Chennai to $100 million bets on non-Nvidia chips. Dropbox’s move is the storage version of the same trend: the pipes and warehouses of the AI economy are being bought, built and fought over.
