Dropbox acquires Tigris Data for $350 million to launch AI storage platform DBX Agent Cloud

Dropbox's largest acquisition

Dropbox announced Thursday plans to acquire Tigris Data, a cloud technology company founded by former Uber engineers, for $350 million in cash. The transaction, disclosed in an SEC 8-K filing dated November 3, appears to be the largest acquisition in Dropbox's history.

The deal is expected to close in the fourth quarter of 2026, Dropbox told TechCrunch. The company also said it currently has no plans to reduce headcount as part of the acquisition. This follows a 9 percent global workforce reduction last month, as reported by the Wall Street Journal.

Dropbox has previously acquired several AI-focused companies, including Reclaim.ai, Promoted.ai, and Mobius Labs. The Tigris deal represents a significant escalation in both scale and strategic ambition — moving from AI features to AI infrastructure.

What Tigris Data brings

Tigris Data provides cloud storage technology that helps businesses store and access data across different regions. Its platform automatically positions data closer to the users and computing resources that need it, helping reduce access times and improve performance — a critical capability for AI workloads that need fast access to training data and model artifacts.

The company raised $25 million in a Series A funding round last year. Its founders are former Uber engineers who helped develop the ride-hailing company's storage infrastructure, giving them deep experience in building storage systems that operate at massive scale.

The New Stack noted that Tigris represents a strategic alternative for Dropbox after the company moved away from AWS S3 for its own storage needs. Tigris's S3-compatible API means DBX Agent Cloud will let businesses purchase storage independently and use it with existing tools and applications built for Amazon S3.

DBX Agent Cloud: Dropbox's AI storage play

DBX Agent Cloud will initially offer object storage as a standalone product. Dropbox says businesses will be able to purchase storage independently and use it with existing tools and applications built for Amazon S3. The company plans to expand the platform with additional capabilities designed to help AI systems work with different types of content, including documents, images, audio and video.

Planned additions include filesystem features that will allow AI agents to manage files and maintain continuity across tasks and sessions. This positions DBX Agent Cloud as infrastructure specifically designed for the agent era, where AI models need persistent, reliable storage between inference calls.

Beyond its infrastructure ambitions, Dropbox is also bringing more AI capabilities to its core product. Users will be able to ask AI to perform supported tasks using their files, choose between different AI models, and connect their Dropbox content to third-party tools including ChatGPT, Claude and Muse. Dropbox says the updated experience has already reached more than 70,000 teams, with initial rollout available to eligible Standard and Advanced customers in the US, UK and Australia.

Market context

The acquisition comes as cloud storage and AI infrastructure converge. Companies building AI applications need reliable, low-latency object storage for training data, model weights, embeddings, and agent state. Tigris's multi-region architecture directly addresses this need.

Dropbox faces competition from established cloud providers including AWS, Google Cloud and Azure, all of which have their own AI infrastructure offerings. But DBX Agent Cloud aims to differentiate by offering a standalone storage product that works with existing S3-compatible tooling, rather than locking customers into a full cloud ecosystem.

For Dropbox, the deal is a bet that the company can grow beyond its legacy file-sync business, which faces pressure from cloud collaboration tools and AI-native storage startups. The company's own history of successful acquisitions — Reclaim.ai, Promoted.ai and Mobius Labs — suggests management sees AI as the through-line for its next decade of growth. Whether 350 million dollars for Tigris is the right price will depend on how quickly DBX Agent Cloud converts S3-compatible storage customers into recurring revenue.

What the AI product updates mean

Beyond the infrastructure platform, the deal signals a broader strategy shift. Dropbox is positioning its core product as an AI workspace where users can choose which model handles their files — rather than committing to a single provider's assistant. The company says the updated experience with model choice and third-party connections has reached more than 70,000 teams.

That flexibility is a deliberate contrast with competitors that build their assistants around a single model family. By supporting ChatGPT, Claude and Muse alongside its own capabilities, Dropbox keeps itself out of the model wars while still monetizing the workflow layer on top of users' files.

The initial rollout covers eligible Standard and Advanced customers in the United States, United Kingdom and Australia, with broader availability planned for 2027. The strategic logic of the deal is a hedge: if AI agents become the primary interface to enterprise data, the storage layer — and who owns it — becomes more valuable.
