Dropbox has agreed to buy Tigris Data for approximately $350 million in cash as it introduces DBX Agent Cloud, an object-storage offering for developers building AI applications. The deal is not complete: the November 3 agreement targets a fourth-quarter close, subject to customary conditions and purchase-price adjustments.
The big change
- Developers will be able to buy storage independently.
- Supported applications use an S3-compatible interface.
- Further capabilities remain planned.
A storage layer for AI applications
Dropbox says the planned acquisition will accelerate its expansion into AI infrastructure. Agent Cloud begins with standalone, S3-compatible object storage. The company points to datasets, model artifacts and media that AI applications may need across compute environments.
In Amazon’s description of S3, a bucket holds objects, each consisting of data and descriptive metadata; a key identifies an object within the bucket. This gives developers a way to store and retrieve application data without organizing it as a traditional shared file drive.
Dropbox says supported S3 tools can work with its offering. Compatibility does not establish identical behavior for every feature or application.
What is available and what is planned
Dropbox plans filesystem and content-processing capabilities for documents and media, according to its November 5 release. Dropbox told The New Stack that it would share integration and availability details as plans develop; the publication reported no launch date had been provided.
Tigris describes its existing service as distributed, S3-compatible object storage on its pricing page. The New Stack reports that, if the deal closes, Tigris technology is expected to underpin Agent Cloud.
