Atlassian, best known for productivity and collaboration software such as Jira and Confluence, announced it will acquire The Browser Company, maker of the Arc and Dia browsers, for $610 million in cash. The move represents an ambitious step into reimagining the internet browser as a workplace productivity tool, particularly for the AI era.

Atlassian CEO and co-founder Mike Cannon-Brookes positioned the acquisition as a bold shift:

“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. 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 deal is expected to close in the second quarter of Atlassian’s fiscal year 2026.

Founded by Josh Miller, The Browser Company is best known for its Arc browser, which drew attention for its innovative user interface. In mid-2025, the company placed Arc into maintenance mode—ending new feature development but continuing security and stability updates—while shifting its main focus to building Dia, a new AI-powered browser aimed at cross-platform compatibility and enhanced workplace integration.

Miller confirmed that The Browser Company will continue to operate independently under Atlassian while scaling Dia: “The deal will allow The Browser Company to hire and ship features faster and support multiple platforms.”

The Browser Company most recently raised $50 million in 2024 at a $550 million valuation, bringing its total fundraising to $128 million across multiple rounds. Its investors include some of the most recognizable names in tech:

The acquisition price of $610 million reflects a significant premium over the company’s most recent private valuation, highlighting Atlassian’s confidence in Dia’s role within its AI-powered workplace ecosystem.

The deal comes amid growing interest in rethinking the browser as more than a tool for passive browsing. With businesses increasingly relying on SaaS applications, browsers are becoming productivity hubs.

The acquisition was also announced just a day after a U.S. District Court decision spared Google from being forced to sell Chrome, underscoring how browsers remain central in both competition and antitrust debates.

Atlassian’s move suggests a strategy to differentiate by offering a browser purpose-built for knowledge workers, tightly integrated with its productivity suite and augmented by AI capabilities.

Atlassian’s acquisition of The Browser Company signals a new phase in the evolution of the browser. No longer just a gateway to the internet, the browser is being reimagined as a central hub for knowledge work, where AI integration helps manage the flood of SaaS tools, documents, and workflows.

By bringing Dia into its portfolio, Atlassian is betting that workers want a browser built for productivity first, rather than adapting consumer-focused tools for business needs. If successful, the move could position Atlassian not just as a maker of workplace apps, but as a platform player with influence over the daily flow of work itself.

The deal also highlights growing recognition that browsers — long dominated by Google Chrome — are once again a competitive space. With AI-driven features, browsers may become the next frontier for reshaping how people organize, collaborate, and get work done.
