The Browser Company, maker of Arc and Dia, is being acquired

Mike Cannon-Brookes, the CEO of enterprise software giant Atlassian, was one of the first users of the Arc browser. Over the last several years, he has been a prolific bug reporter and feature requester. Now he’ll own the thing: Atlassian is acquiring The Browser Company, the New York-based startup that makes both Arc and the new AI-focused Dia browser. Atlassian is paying $610 million in cash for The Browser Company, and plans to run it as an independent entity.

The acquisition is mostly about Dia, which launched in June. Dia is a mix of web browser and chatbot, with a built-in way to chat with your tabs but also do things across apps. Open up three spreadsheets in three tabs and Dia can move data between them; log into your Gmail and Dia can tell you what’s next on the calendar. Anything with a URL immediately becomes data available to Dia and its AI models. For a company like Atlassian, which makes a whole suite of work apps — the popular project-tracker Jira, the note-taking app Confluence, plus Trello, Loom, and more — a way to stitch them all together seems obviously compelling.
