Atlassian has taken a major step in its expansion strategy by acquiring The Browser Company, the developer of Arc and the AI-powered browser Dia, in a deal worth 610 million US dollars. This acquisition is seen as a move to strengthen Atlassian’s position in the artificial intelligence era, particularly in the field of digital productivity.

Atlassian is widely known for SaaS products such as Jira, Confluence, and Trello, used by millions of workers worldwide. With this acquisition, Atlassian aims to deliver a browser designed specifically for work, not just for casual web browsing.

Atlassian CEO Mike Cannon-Brookes emphasized that this move is a bold step toward redefining how people use browsers. “This deal is a bold step forward in reimagining the browser for knowledge work in the AI era. Together with The Browser Company, we will create an AI-powered browser optimized for SaaS applications,” he said in an official statement.

The Browser Company introduced Dia in June 2025 as a next-generation browser. Dia is more than a tool for opening web pages. It acts as an AI assistant capable of summarizing information, transferring data between tabs, and even answering questions directly from emails or work documents.

This integration makes Dia more than just a browser. Atlassian sees it as a productivity hub that connects various work applications into one contextual space. This vision aligns with the modern challenge where knowledge workers often lose valuable time switching between different apps.

Although Arc will continue to be maintained, Atlassian confirmed that its main focus is now on Dia. The Browser Company will continue operating independently under Atlassian’s ownership, with the same team and consistent vision.

Josh Miller, CEO of The Browser Company, stressed that Dia is intended for individuals, not just for large corporations. “We want to move faster and dream bigger. Dia is a browser for workers, not just a tool for enterprise IT,” Miller stated.

Through this acquisition, Dia will gain access to more than 300,000 Atlassian customers, including 80 percent of Fortune 500 companies. This means Dia has the potential to become widely adopted in professional work environments around the globe.

In addition, Atlassian’s expertise in operating large-scale AI infrastructure will accelerate Dia’s growth with better security and reliability, something that would be challenging for an independent startup to achieve.

Atlassian’s entry into the AI browser market comes at a time when competitors are also moving quickly. Brave is working with Leo, Microsoft is developing Edge Copilot, and Google is integrating AI into Chrome.

Dia’s main advantage lies in its deep integration with Atlassian’s SaaS ecosystem. This provides strong differentiation, as Dia is designed primarily for productivity, not just for browsing the web.

The acquisition is still pending regulatory approval. Atlassian expects the transaction to close in the second quarter of its 2026 fiscal year, between October and December 2025. The deal will be fully funded from Atlassian’s cash reserves, reflecting the company’s strong confidence in Dia’s future.

Integrating an AI-powered browser like Dia could transform how workers interact with software. Atlassian aims to reduce wasted time caused by switching between tabs, improve team collaboration, and deliver a smoother work experience.

With this move, Atlassian also strengthens its position as a leading player in the AI-driven work revolution. The combination of an established SaaS ecosystem and an innovative AI browser is expected to create a new standard for digital productivity.
