Atlassian Snaps Up Browser Startup as Work Moves to AI

Atlassian is acquiring The Browser Company for $610 million in a move that aims to transform how knowledge workers interact with the web. The acquisition will be completed in the second quarter of Atlassian’s fiscal year 2026, expected to conclude in December, subject to regulatory approval. Atlassian’s purpose is to turn the AI-powered Dia browser into a productivity platform integrated with its suite of work tools.

The offer values the New York-based startup at roughly $610 million in cash and reflects Atlassian’s confidence in the AI-driven browser segment. The Browser Company will continue to operate independently, with its AI browser Dia — and not Arc — as the focus for integration across Atlassian’s ecosystem.

This Atlassian Snaps Up Browser Startup strategy is a direct effort to reimagine the browser as a contextual, intelligent workspace rather than a passive tool for browsing. Mike Cannon-Brookes, Atlassian’s CEO, urged that “today’s browsers were built for browsing, not work,” underlining the need for a browser that actively assists with tasks across SaaS applications.

Josh Miller, CEO of The Browser Company, stressed that despite the acquisition, the focus remains on individuals using Dia at work — not on serving enterprise IT exclusively. He highlighted that working “means we can move faster, dream bigger, and focus on building an AI browser for work that people genuinely love to use.”

The timing is significant. Dia, launched in June, enables users to traverse and manipulate data across tabs and apps using AI, a capability Atlassian sees as a natural fit with its products like Jira, Confluence and Trello. Analysts view this acquisition as a bet on an emerging category of “AI browsers,” with competitors such as Perplexity’s Comet, Brave’s Leo, Microsoft Edge’s Copilot integration and OpenAI’s own browser developments.
