On November 5, Dropbox announced plans to acquire cloud storage company Tigris Data for $350 million, and unveiled the DBX Agent Cloud object-storage product for AI developers on the same day. Dropbox confirmed to the press that this is its largest acquisition since it was founded in 2007 — a company built on file sync is now formally betting on AI infrastructure.
Who is Tigris, and what is Dropbox buying?
Tigris was founded in 2021 in Sunnyvale, California, by former Uber engineers, and it builds a network of localized storage centers for distributed AI workloads: data sits closer to the compute, serving applications deployed across clouds. The company has raised about $31.9 million in total, including a $25 million Series A in October 2025 led by Spark Capital, with a16z and Basis Set participating. What Dropbox wants is exactly that capability: its users long ago stopped just syncing files, and the images, video, and massive files needed to train and run models need a cheap, fast, cross-cloud object storage layer too. The deal is expected to close in the fourth quarter of 2026, and Dropbox says the acquisition involves no layoffs.
DBX Agent Cloud: sell storage first, talk agents later
DBX Agent Cloud, unveiled the same day as the acquisition, is Dropbox's new product for businesses and developers: it starts with standalone S3-compatible object storage for teams building AI models and agents, first available to eligible Standard-plan teams. The 'Agent' in the name is not a gimmick: agent workflows constantly read and write large volumes of unstructured data, and storage latency and cost decide whether they can run at all. Dropbox has previously acquired AI companies such as Reclaim.ai, Promoted.ai, and Mobius Labs, but Tigris is its first deal that directly buys infrastructure. Whether it can move from consumer sync into developer infrastructure will be answered by the first wave of DBX Agent Cloud user feedback.
For Dropbox, the risk in this deal is just as direct: object storage is the home turf of the public cloud giants, price wars are fierce, and whether Tigris's localized network can beat hyperscalers on cost is still unknown. $350 million buys a ticket in, not a win.
