Atlassian buys The Browser Company for $610M to build AI work browser

Productivity software giant Atlassian has agreed to acquire The Browser Company, maker of the Arc and Dia browsers, in a $610 million all-cash deal.
Atlassian CEO and co-founder Mike Cannon-Brookes framed the acquisition as a major leap in rethinking the role of the browser in modern knowledge work.
“Today’s browsers weren’t built for work; they were built for browsing. This deal is a bold step forward in reimagining the browser for knowledge work in the AI era,” Cannon-Brookes said in a statement.
“Together, we’ll create an AI-powered browser optimized for the many SaaS applications living in tabs – one that knowledge workers will love to use every day.”
The Browser Company’s Next Chapter
Founded in 2019, The Browser Company first gained attention for its innovative Arc browser, designed to rethink tab and workspace management. In 2024, the company pivoted to developing Dia, a new browser tailored for productivity.
CEO Josh Miller confirmed in a post on X that the startup will continue to operate independently under Atlassian’s umbrella, with development of Dia remaining the core focus. Miller emphasized that the deal would allow the team to hire faster, expand across platforms, and accelerate feature development.
Deal Structure and Timeline
The acquisition is expected to close in the second quarter of Atlassian’s fiscal year 2026.
The Browser Company most recently raised $50 million in 2024 at a valuation of $550 million, bringing its total funding to $128 million. Its investor roster includes Pace Capital, LinkedIn’s Jeff Weiner, Medium’s Ev Williams, Figma’s Dylan Field, Notion’s Akshay Kothari, and GitHub’s Jason Warner.
Industry Context
The deal highlights growing competition in the browser space at a time when AI integration is reshaping productivity tools. The announcement comes just a day after a U.S. District Court ruling spared Google from being forced to divest its Chrome browser, underscoring the heightened regulatory and competitive pressures around web technologies.
For Atlassian—best known for collaboration software like Jira, Confluence, and Trello—the acquisition signals a strategic push into the browser itself as the next battleground for workplace productivity.
