Productivity software maker Atlassian has agreed to acquire The Browser Company, which makes the Arc and Dia browsers, for $610 million in cash.
“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,” Mike Cannon-Brookes, Atlassian’s CEO and co-founder, 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,” he added.
The Browser Company’s CEO Josh Miller, said on a post on X that his company will operate independently under Atlassian and will continue to develop Dia, the browser it started working on last year after deciding to stop development of its previous browser, Arc.
Miller said that the deal would allow The Browser Company to hire and ship features faster and support multiple platforms.
The deal is expected to close in the second quarter of Atlassian’s fiscal year 2026.
The Browser Company most recently raised $50 million at a $550 million valuation last year. The startup has so far raised $128 million in total across multiple rounds, and its investors include Pace Capital, LinkedIn’s Jeff Weiner, Medium’s Ev Williams, Figma’s Dylan Field, Notion’s Akshay Kothari, and GitHub’s Jason Warner.
