Dropbox to buy AI storage startup Tigris Data for $350M
Dropbox (NASDAQ: DBX) said in a Business Wire release on November 5, 2026 that it plans to acquire Tigris Data Inc., a Sunnyvale, California company that runs a globally distributed object storage platform built for AI workloads. A Form 8-K filed with the SEC shows the parties signed a definitive agreement on November 3 to buy all outstanding equity for about $350 million in cash, subject to customary purchase price adjustments. Closing is expected in the fourth quarter of 2026, if customary conditions are met. Crunchbase News reported that the deal would be Dropbox's largest acquisition since its founding in 2007.
Alongside the deal, Dropbox introduced DBX Agent Cloud, a storage and data layer for companies and developers building AI applications and agents. The first version is standalone, S3-compatible object storage that works with tools already built for Amazon S3. Dropbox plans to add filesystem features that let agents manage files across tasks and sessions, along with content-processing tools for documents, images, audio and video. Tigris, founded by former Uber engineers, lets applications run across several public clouds and places data nearer to the compute that needs it.
Tigris raised a $25 million Series A in October 2025, led by Spark Capital, according to Crunchbase, which puts its total disclosed funding at about $31.9 million. Dropbox has not said how the two technologies will be integrated, and it has not announced a launch date for DBX Agent Cloud.
Why it matters
For teams building AI products, the price says something about where value sits. Tigris had disclosed about $31.9 million in total funding, so the $350 million figure is roughly 11 times that amount. Buyers appear to be paying for a system already running in production, an experienced engineering group and existing ties to AI developers, which is the case Dropbox's chief business officer made to Crunchbase News.
For founders selling to AI developers, the deal shows that S3 compatibility, multi-cloud placement and a current zero egress fee policy can attract a strategic buyer. For investors, it suggests that file and collaboration vendors will hunt for similar infrastructure assets, and that developer-led storage products will be valued against both cloud incumbents and specialist providers.
