Atlassian announces agreement to acquire The Browser Company

Atlassian Corporation, a leading provider of team collaboration and productivity software, announced an agreement to acquire The Browser Company, the company behind the Dia and Arc browsers—with the goal to deliver the “browser for knowledge work in the AI era.”

Today’s browsers were built before the explosion of SaaS apps, and well before the current AI revolution, according to the vendors.

Atlassian and The Browser Company intend to change this by making Dia the AI browser for work, that is:

• Optimized 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.
• Built with trust and security in mind, so company data is protected.

“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,” said Mike Cannon-Brookes, Atlassian’s CEO and co-founder. “By combining The Browser Company’s passion for building beloved browsers with our two decades of understanding how knowledge workers operate, we see a huge opportunity to transform the way work gets done. 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."

With more than 300,000 customers already relying on Atlassian apps to drive work forward, Atlassian can bring Dia to millions of new users, the company said.

“For laptop workers, your browser is where your job actually happens—where you spend hours working within tabs every day,” said Josh Miller, The Browser Company’s CEO and co-founder. “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.”

Under the terms of the definitive agreement, Atlassian will acquire The Browser Company for approximately $610 million in cash, inclusive of The Browser Company’s cash balance, subject to customary adjustments.

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