Dropbox plans to buy AI storage startup Tigris for $350 million, its biggest deal ever, and says more AI is coming to the files you already keep there.
Dropbox plans to buy a startup called Tigris Data for $350 million. The company says it would be its largest acquisition since it was founded in 2007. The deal is a sign that Dropbox wants to be more than a place to store and share files. It also wants to sell storage to the people who build AI tools.
Dropbox announced the plan on Thursday, along with what it calls a significant shift in its AI strategy. It also launched DBX Agent Cloud. At first, this will offer standalone object storage. That is a way to store and retrieve very large collections of data, such as images, video and the files used to train and run AI models.
Tigris is based in Sunnyvale, California. Former Uber engineers started it in 2021. It is building a network of local data storage centers that it says can handle the spread-out computing needs of modern AI work. Its product is aimed at developers whose apps run across several cloud providers.
Tigris serves a different crowd than Dropbox's usual customers. Still, Dropbox is also adding AI to its regular product. Chief business officer Eric Webster said the company is bringing AI to your files to help you find, understand, create, edit and organize content. Customers can switch between supported AI models. They can also work with Dropbox files in tools like ChatGPT and Claude, with results returning to Dropbox.
Dropbox has made 35 known acquisitions, many of them between 2012 and 2015. It made four across 2024 and 2025. Its next largest deals were HelloSign in 2019 at $230 million, DocSend in 2021 at $165 million and FormSwift in 2022 at $95 million.
Webster said Tigris brings a product already running in production, an experienced team and relationships with AI developers. He said that would speed Dropbox's entry into infrastructure for AI applications.
The deal is described as planned, so it is not final. The material does not say when it might close. It also does not give pricing for DBX Agent Cloud or dates for the new AI features inside Dropbox. Those details are worth watching for.
Dropbox is betting big on AI, so expect more AI features in your files, though timing and pricing are not yet clear.
