Atlassian Acquires The Browser Company for $610 Million

Atlassian Corporation, a leading provider of team collaboration and productivity software, on Thursday said that it has agreed to acquire The Browser Company, the company behind the Dia and Arc browsers for $610 million in an all-cash deal, inclusive of The Browser Company’s cash balance, subject to customary adjustments.

The transaction will be funded through cash from Atlassian’s balance sheet and is expected to close in the second quarter of its fiscal year 2026, subject to customary closing conditions and required regulatory approvals.

The acquisition is not expected to have a material impact on the company’s financials in fiscal years 2026 and 2027.

Together, the companies intend to deliver the browser for knowledge work in the AI era. The present day’s browsers were built before the explosion of SaaS apps, and well before the current AI revolution.

Optimised to appeal to the consumer masses, browsers were not designed for the knowledge workers who rely on them to get things done. For these workers, each tab contains a different workflow to move forward – a meeting to schedule, a design to review, a memo to write. Current browsers are passive bystanders, unaware of that context and unable to connect business processes, holding up work.

Atlassian and The Browser Company intend to change this by making Dia the AI browser for work, that is optimised for the SaaS apps where knowledge workers spend their day. Whether work is happening in email, a project management tool, or a design app, tabs will be enriched with context that helps move work forward, packed with AI skills and personal work memory to connect the dots between apps, tabs, and tasks; and built with trust and security in mind, so company data is protected.

Huge Opportunity for Atlassian

Mike Cannon-Brookes, Atlassian’s CEO and co-Founder, said that today’s browsers were not built for work but only browsing. This deal is a bold step forward in reimagining the browser for knowledge work in the AI era.

According to him, by combining The Browser Company’s passion for building beloved browsers with our two decades of understanding how knowledge workers operate, Atlassian see a huge opportunity to transform the way work gets done.

With more than 300,000 customers – including over 80% of the Fortune 500 – relying on Atlassian apps to drive work forward, Atlassian has the opportunity to bring Dia to millions of new users. Complementing this reach is Atlassian’s expertise in operationalising AI at scale, with over 2.3 million monthly active users of AI capabilities across its platform – growing more than 50 percent quarter-over-quarter. Together, these strengths will accelerate the companies’ shared vision for the future of work.

The Browser Company’s CEO and co-founder Josh Miller said that for laptop workers, their browser is where the job actually happens – where the workers spend hours working within tabs every day.

“That context, plus access to your tools, is incredibly valuable for AI. Atlassian gets that. Teaming up means we can move faster, dream bigger, and focus on building an AI browser for work that people genuinely love to use – one that is trusted by companies but feels personal to every individual,” he added.
