Dropbox to Buy Tigris for $350M and Sell Storage for AI Apps

Dropbox plans to buy Tigris Data, a storage startup built for AI workloads, for $350 million.

It told Crunchbase News that’s its biggest acquisition since it was founded in 2007.

The Tigris deal hasn’t closed yet.

So if you build a SaaS product or an AI tool, Dropbox now wants to be the place where your app’s files live, and on November 5 it announced a new product line to do it.

What Dropbox is launching

It’s called DBX Agent Cloud. For now it does one thing.

It starts with standalone object storage that works with Amazon S3 tools, and you can buy it on its own, says Dropbox’s announcement.

The pitch is a home for the heavy files AI apps need.

Think training data, model files, images and video.

Then come two more pieces, with no dates yet:

• filesystem features, so agents keep a place for their files across tasks and sessions
• content processing, which turns documents, audio and video into inputs a model can use

What’s Tigris, then? A Sunnyvale startup founded by former Uber engineers. It says it stores data across clouds with no lock-in or egress fees.

Crunchbase puts its funding at about $32 million, most of it from a $25 million Series A in October 2025.

What changes inside Dropbox itself

Meanwhile, regular Dropbox gets AI that works on your files in Dropbox.

You describe a task, Dropbox shows you a plan, and it only acts after you approve it, with a record of each change and an undo for supported ones.

Here are some of the jobs it takes on:

• summarizing folders and comparing versions of a file
• editing PDFs and images
• transcribing recordings and editing video clips
• drafting documents from a project’s files, then moving or renaming files in several steps from one request

You can open your Dropbox files in ChatGPT, Claude and Muse, too, and the results go straight back into Dropbox.

More than 70,000 teams in the US, UK and Australia already have it. Wider availability is planned for 2027.

Why it matters

Storage bills are where small SaaS teams get surprised, usually months after you picked a provider, wired your uploads into it and stopped checking what each gigabyte costs you.

You saw it when Vercel started billing Data Cache use, and in my experience egress fees bite the same way on the big clouds, usually in the month your app finally gets busy.

So another option from Dropbox is good news for you. I think more choice usually means better prices.

Still, I wouldn’t move yet. Three things are missing:

• DBX Agent Cloud’s prices, which neither announcement gives
• a closing date for the Tigris deal
• dates for the filesystem and content processing features

Already a Tigris customer? Neither announcement says what changes for you, though CEO Ovais Tariq says Dropbox’s experience would help Tigris support larger workloads.

My read: Dropbox wants a second engine next to file sharing, and Tigris hands DBX Agent Cloud a product already in production, with AI developers as customers on day one.

It’s a familiar move, like Freshworks buying Robusta last month.

Storing your app’s uploads on S3 today? Watch for DBX Agent Cloud’s prices. That said, I’d expect S3 compatibility to make a switch fairly painless once the Tigris deal closes.
