Atlassian acquires Arc browser maker for $610M to build AI work browser

Atlassian is acquiring The Browser Company, maker of the Arc browser and upcoming AI-focused Dia browser, for $610 million in an all-cash deal expected to close by the end of 2025. The acquisition positions Atlassian, owner of productivity tools like Jira and Trello, to expand beyond its current software portfolio into the emerging AI-powered browser market, with plans to accelerate Dia’s development as “the AI browser for work.”

Key details: The Browser Company will maintain operational independence while building out Dia, which launched in private beta in June.

• Co-founders Josh Miller and Hursh Agrawal will remain as CEO and CTO, respectively, continuing to lead the company’s browser innovation efforts.
• The existing Arc browser (now in maintenance mode) and Arc Search will continue operating, with long-term plans to be announced soon.
• Miller said the company had three non-negotiable conditions: maintaining independence, preserving all team jobs, and keeping Dia’s vision central to operations.

Strategic alignment: Atlassian CEO Mike Cannon-Brookes outlined plans to integrate Dia with the company’s enterprise software ecosystem.

• “Our vision is to make Dia the AI browser for work,” Cannon-Brookes said, describing it as “optimized for the SaaS apps where you spend your day; packed with AI skills and your personal work memory to unleash your potential.”
• Miller emphasized the cultural fit: “We chose Atlassian because their strengths complement our gaps. And most importantly, like us, they believe the browser is becoming the new operating system.”

What they’re saying: Miller highlighted values alignment as a key factor in selecting Atlassian as an acquisition partner.

• “A large part of why we chose Atlassian is values. Now more than ever. Not the kind you hang on a wall, but the ones you see in the work itself,” Miller wrote in a blog post announcing the deal.

The bigger picture: This acquisition reflects growing enterprise interest in AI-native browsing experiences as companies seek integrated productivity solutions.

• Atlassian’s productivity tools like Jira and Trello position Dia to potentially integrate with existing enterprise workflows.
• The deal comes as Atlassian recently laid off around 150 customer service workers, reportedly planning to replace some functions with AI automation.

Timeline: The Browser Company plans to accelerate Dia’s rollout “to every platform faster than we could have previously imagined” in the coming months, leveraging Atlassian’s resources and enterprise relationships.
