Dropbox is making a big push into AI infrastructure with a $350 million acquisition of cloud technology company Tigris Data, marking what appears to be its largest acquisition to date.

Announced Thursday, the deal is expected to strengthen Dropbox’s AI infrastructure capabilities and support the development of DBX Agent Cloud, a new storage platform aimed at businesses and developers building AI models and agents.

Dropbox told TechCrunch via email that the transaction is expected to close in the fourth quarter of 2026. The company also said it currently has no plans to reduce headcount as part of the acquisition. The company already cut 9% of its global workforce last month, WSJ reported. 

DBX Agent Cloud will initially offer object storage as a stand-alone product, allowing businesses to purchase storage independently and use it with existing tools and applications built for Amazon S3 (Simple Storage Service), which is a cloud storage service that enables businesses to store and retrieve large volumes of data.

Beyond its infrastructure ambitions, Dropbox is also bringing more AI capabilities to 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.
