Dropbox has agreed to acquire Tigris Data for $350 million, marking what appears to be its largest acquisition to date and part of a broader push into AI infrastructure. The deal was announced Thursday and is expected to close in the fourth quarter of 2026. Dropbox told TechCrunch it currently has no plans to reduce headcount as part of the acquisition, though the company cut 9% of its global workforce last month, according to WSJ.

The acquisition supports development of DBX Agent Cloud, a storage platform for businesses and developers building AI models and agents. DBX Agent Cloud will initially offer object storage as a standalone product, allowing customers to buy storage independently and use it with existing tools and applications built for Amazon S3. Dropbox also plans to add capabilities that help AI systems work with different content types, including documents, images, audio, and video, along with filesystem features that let AI agents manage files and maintain continuity across tasks and sessions.

In parallel, Dropbox is expanding AI features in its core product. Users will be able to ask AI to perform supported tasks using their files, choose between different AI models, and connect Dropbox content to third-party tools including ChatGPT, Claude, and Muse. Dropbox says the updated experience has reached more than 70,000 teams. The initial rollout is available to eligible Standard and Advanced customers in the U.S., U.K., and Australia, with broader availability planned for 2027.

Tigris Data was founded by former Uber engineers who helped develop the ride-hailing company’s storage infrastructure. The company provides cloud storage across regions and automatically positions data closer to the users and computing resources that need it, reducing access times. Tigris raised $25 million in a Series A round last year. Dropbox has previously acquired several AI-focused companies, including Reclaim.ai, Promoted.ai, and Mobius Labs.
