Atlassian to Buy The Browser Company for $610 Million to Advance an AI Browser for Work

Atlassian targets a work-focused AI browser by centering Dia with enterprise-grade controls.

Overview

  • The $610 million cash deal is expected to close in Atlassian’s fiscal second quarter, which ends in December 2025.
  • Atlassian says The Browser Company will operate independently, with Dia positioned as the flagship AI-first browser for work.
  • CEO Mike Cannon-Brookes plans to blend Arc’s power-user features with Dia’s AI and Atlassian’s enterprise expertise to deliver a managed, secure work browser.
  • Arc will remain maintained but is no longer in active feature development following the company’s pivot to Dia.
  • The move seeks distribution and scale in a rapidly evolving AI browser market; prior backers include Atlassian Ventures, Salesforce Ventures, Dylan Field and Reid Hoffman.
