Dropbox is putting roughly $350 million in cash behind a push into AI infrastructure. In an 8-K filed Thursday, the company said it signed a definitive agreement on Nov. 3 to buy all of the outstanding equity of Tigris Data Inc., a globally distributed object-storage platform built for AI workloads, subject to customary purchase-price adjustments. Closing is expected in the fourth quarter of 2026 if customary conditions are met.
The same filing attached a press release that also unveils DBX Agent Cloud, a storage and data layer for companies and developers building AI applications and agents. The first piece is standalone, S3-compatible object storage that customers can buy on its own and use with tools and apps already built for Amazon S3.
“The value of AI depends on the content and context it can work with,” Ashraf Alkarmi, co-CEO of Dropbox, said in the company blog post. “We’re bringing AI to the work people already keep in Dropbox and extending our storage expertise to companies building AI applications. Across both, our goal is to give customers the freedom to choose how they use AI while keeping control of the content they depend on.”
What Tigris customers keep, and what Dropbox wants next
Tigris told customers Thursday that the product, S3-compatible API, pricing with zero egress fees, and support channels stay the same while the deal progresses. The startup, founded by former Uber engineers, markets intelligent data placement meant to keep latency low without forcing buyers onto a single cloud. Dropbox said Tigris will help it enter AI infrastructure on top of nearly two decades of running storage at scale.
After object storage, Dropbox plans filesystem features so agents can keep working across sessions, plus content processing that turns documents, images, audio, and video into AI-ready inputs. “AI is driving storage demand at a scale this industry has not seen before,” Ovais Tariq, co-founder and CEO of Tigris, said in the Dropbox blog post. “Meeting it takes massive scale and a conviction we share with Dropbox: that customers should have the flexibility to run their compute wherever it serves them best, with a product built for developers and agents alike.”
TechCrunch reported that Dropbox described the Tigris deal as expected to close in the fourth quarter of 2026 and said it currently has no plans to cut headcount as part of the acquisition. The outlet also noted Tigris raised a $25 million Series A last year and that Dropbox has previously bought AI-focused firms including Reclaim.ai, Promoted.ai, and Mobius Labs. TechCrunch said the deal appears to be Dropbox’s largest acquisition to date.
AI inside Dropbox, not only under it
Alongside the infrastructure bet, Dropbox is rolling out a new experience that lets customers ask the product to find and summarize content, draft and edit files, organize folders, and run multi-step actions after they approve a plan. Results stay tied to existing folders, permissions, and sharing. Customers can switch supported models in a session and open Dropbox files in tools such as ChatGPT, Claude, and Muse without re-uploading, with work returning to Dropbox.
That experience has already reached more than 70,000 teams, Dropbox said, starting with eligible Standard and Advanced teams in the United States, United Kingdom, and Australia, in English, with broader availability planned for 2027. The company said it has more than 700 million registered users across about 180 countries.
The move sits beside other large software deals that are reshaping how SaaS vendors own data and AI distribution, including Salesforce’s agreement to buy Braze. Dropbox has also been tightening account rules ahead of a 2027 overhaul, as WebProNews covered earlier this fall, while older product work such as end-to-end encryption and Microsoft 365 co-authoring kept the focus on files people already store there.
Closing still depends on customary conditions. Until then, Tigris said customers can keep using the service as they do today.
