Dropbox: Plans to buy Tigris Data, targets AI storage

Dropbox announced plans to acquire Tigris Data on 5 November 2026, expanding into storage infrastructure for companies building artificial intelligence applications. The company outlined the proposed purchase in a press release, while Crunchbase News reported a $350 million price and said Dropbox described it as its largest acquisition to date.

Alongside the deal, Dropbox unveiled DBX Agent Cloud, a storage and data infrastructure offering for developers, and announced AI features for its existing file-sharing product. The announcements address two different audiences: businesses building AI applications and customers seeking to use AI on content already stored in Dropbox.

The transaction is proposed, not completed. Dropbox told TechCrunch that it expected the acquisition to close in the fourth quarter of 2026 and had no plans to reduce headcount as part of the purchase.

What Tigris brings to Dropbox

Dropbox described Tigris as a globally distributed object-storage platform designed for AI workloads. Object storage holds data as individual named objects, grouped into containers called buckets, rather than requiring applications to manage a conventional folder structure, according to an explanation published by infrastructure provider Fly.io.

For AI developers, the material being stored can include training datasets, model files, images and video. Dropbox said its infrastructure strategy is intended to give that content a consistent home even as customers change the models, applications or computing providers they use.

Tigris was founded by former Uber engineers. In its own company history, Tigris said its founders worked together on Uber’s global storage platform before starting the business.

Fly.io, which describes Tigris as running on its infrastructure, explained that Tigris uses global buckets rather than asking developers to select individual storage locations. Its routing system makes and stores copies of data where demand arises. That design is intended to reduce the delay between an application requesting data and receiving it.

Dropbox’s announcement described Tigris as enabling customers to store and access data across cloud providers without being tied to one supplier. These are descriptions of the platform’s design and intended benefits, rather than evidence of how it will perform after integration with Dropbox.

Eric Webster, Dropbox’s chief business officer, told Crunchbase News that Tigris offered an existing production product, an experienced team and relationships with AI developers. He said that combination would accelerate Dropbox’s entry into infrastructure for AI applications through DBX Agent Cloud.

Tigris co-founder and chief executive Ovais Tariq, quoted in Dropbox’s announcement, said combining the companies would help Tigris support larger workloads while maintaining its focus on reliability and direct technical collaboration with developers.

DBX Agent Cloud starts with standalone storage

Dropbox said DBX Agent Cloud would begin with standalone, S3-compatible object storage. S3 refers to Amazon Simple Storage Service; compatibility means customers can use familiar tools and supported applications built for that service.

Companies will be able to buy the storage independently, according to Dropbox. The offering is designed to operate alongside customers’ existing cloud services, computing providers and developer platforms, rather than requiring their applications to run entirely within Dropbox.

The company plans to add filesystem and content-processing capabilities. Its announcement distinguished those planned additions from the initial object-storage offering.

Filesystem capabilities would give applications and AI agents a persistent place to manage files and continue work across tasks and sessions. Content processing would turn documents, images, audio and video into inputs AI systems can use, Dropbox said.

In its technical writing, Dropbox describes AI agents as systems that break a request into steps, use available resources to execute those steps and generate a response. Storage for such systems therefore serves a different purpose from an individual uploading a document to share with colleagues: it supplies the data and continuing workspace behind an application.

Webster told Crunchbase News that DBX Agent Cloud opens a developer and infrastructure market for Dropbox, while AI within its existing product is intended to strengthen customer engagement, retention and expansion.

A larger purchase after earlier AI acquisitions

Crunchbase News reported that Tigris raised $25 million in an October 2025 Series A funding round led by Spark Capital, with participation from Andreessen Horowitz and Basis Set Ventures.

The proposed $350 million purchase exceeds several of Dropbox’s earlier acquisitions. According to Crunchbase News, Dropbox bought electronic-signature company HelloSign for $230 million in 2019, document-sharing platform DocSend for $165 million in 2021 and business-forms provider FormSwift for $95 million in 2022.

The publication also reported that Dropbox acquired scheduling startup Reclaim.ai and document-security company Nira in 2024, followed by Promoted.ai and Mobius Labs in 2025. The Tigris announcement extends that acquisition activity into the storage infrastructure used by developers, rather than only tools for managing work and content.

Existing Dropbox files get AI actions

For existing customers, Dropbox said its updated experience can identify relevant content, propose a plan and perform supported actions after approval.

The company’s examples include summarising folders, comparing document versions, drafting from project material, editing PDFs and images, transcribing recordings and refining video clips. It also described support for organising folders and moving or renaming files through multistep requests.

Dropbox said the system works within existing permissions, records its actions and allows customers to review changes and undo supported actions. These are the controls the company describes for the product, not a guarantee that every AI-generated change can be reversed.

Customers can also switch between supported AI models during a session and work with Dropbox files through supported external tools, including ChatGPT, Claude and Muse, with resulting work returning to Dropbox, the company said.

Dropbox reported that the updated experience had reached more than 70,000 teams by its 5 November announcement. The initial English-language rollout covers eligible Standard and Advanced teams in the US, UK and Australia. The company plans broader availability in 2027; its announcement did not specify an India launch date.
