Atlassian has announced an agreement to acquire The Browser Company, maker of the Arc and Dia browsers, in a $610 million cash deal. The acquisition, expected to close in the second quarter of fiscal year 2026, will allow Atlassian to accelerate its vision of developing an AI-powered browser tailored for knowledge work.
