Atlassian said it agreed to acquire The Browser Company, maker of Arc and Dia, for about $610 million in cash, a bid to build an artificial intelligence-powered browser designed for workplace use. The deal is expected to close in the second quarter of Atlassian’s fiscal 2026, subject to regulatory approvals, and The Browser Company will operate independently within Atlassian.
The company framed the purchase as a strategic move to reimagine the browser around knowledge work, with Dia positioned as an enterprise-grade, AI-first application optimized for the SaaS tools office workers use every day. Plans include context-aware tabs, compliance and administrative controls, and tighter integration across email, project management and design platforms.
Atlassian said the transaction will be funded from its balance sheet and is not expected to have a material financial impact in fiscal 2026 or 2027. The company cited its reach — more than 300,000 customers, including over 80% of the Fortune 500 — and 2.3 million monthly active users of AI features across its products as distribution and adoption advantages for Dia.
The Browser Company will focus on professional use cases while maintaining cross-platform support and secure syncing, with Arc continuing to be supported during the transition. Dia is set to become the flagship work browser, with select features from Arc incorporated over time.
The deal comes amid growing competition to bring AI into the browser experience. Atlassian positioned the acquisition as a long-term bet that the browser — where most enterprise workflows already occur — can serve as a secure, controllable entry point to work across its software suite.
