Atlassian said it will acquire the Browser Company of New York, which is the company behind the Dia and Arc browsers, in a $610 million bet that enterprises need secure browsers designed for SaaS and AI applications.

The purchase comes as browsers are seen as critical software for everything from knowledge work to agentic AI.

Atlassian said that browsers are typically built for consumers and not workers that need to get work done in sometimes dozens of tabs. Atlassian is betting that the browser can enable new collaborative workflows.

According to Atlassian CEO Mike Cannon-Brookes, the plan is to make The Browser Company's Dia the AI browser for work optimized for SaaS with security built in and personal work memory.

In a statement, Cannon-Brookes said:

"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."

As for distribution, Atlassian can bring Dia to its more than 300,000 customers and more than 2.3 million active users of AI on its platform.
