Atlassian’s Largest Acquisition Ever: DX for $1 Billion

In a move that signals Atlassian’s serious commitment to developer experience and productivity, the company announced its acquisition of DX, a developer productivity insight platform, for a staggering $1 billion in cash and restricted stock. This marks Atlassian’s largest acquisition to date, even surpassing their famous Trello acquisition in 2017.

DX, founded by Abi Noda and Greyson Junggren, specializes in analyzing engineering team productivity and identifying bottlenecks that slow down development. What makes this acquisition particularly strategic is that 90% of DX’s customers were already using Atlassian tools, creating natural synergies.

The timing is particularly significant as companies worldwide are scrambling to measure the ROI of their AI investments. DX’s platform provides both qualitative and quantitative metrics that help organizations understand not just what’s slowing them down, but how to fix it.

The Browser Company Joins Atlassian for $610 Million

Just two weeks before the DX announcement, Atlassian made another bold move by acquiring The Browser Company, creators of the innovative Arc and Dia browsers, for $610 million in cash. This acquisition represents Atlassian’s vision for the future of work interfaces in the AI era.

The acquisition is fascinating for several reasons. Arc, known for its innovative approach to tab management and workspace organization, has garnered a cult following among power users. Dia, the company’s newer project, focuses on AI-powered browsing experiences. Together with Atlassian’s enterprise expertise, this creates an opportunity to revolutionize how knowledge workers interact with SaaS applications.

The Browser Company will continue to operate independently under Atlassian, with CEO Josh Miller confirming that development of both Arc and Dia will continue. The deal is expected to close in Atlassian’s fiscal Q2 2026, pending regulatory approvals.

Interestingly, this acquisition came after reports that both OpenAI and Perplexity were interested in acquiring The Browser Company, highlighting the strategic value of browser technology in the AI age.

Rovo AI: From Premium Add-on to Standard Inclusion

Perhaps the most immediately impactful announcement for existing Atlassian customers is the inclusion of Rovo AI in all paid plans at no additional cost. Previously priced at $20 per user per month, Rovo is now bundled with Standard, Premium, and Enterprise subscriptions for Jira, Confluence, and Jira Service Management.

The September 2025 update brought significant enhancements to Rovo Chat, including improved memory and personalization tied to user profiles, the ability to handle complex multi-step tasks autonomously, and expanded actions across third-party applications like creating Google Docs, scheduling meetings, and sending Slack messages.

According to Atlassian’s research, knowledge workers spend 25% of their time searching for information – that’s 2.4 billion hours wasted annually. Rovo’s integration aims to dramatically reduce this time, with early users reporting 60% better success rates compared to traditional enterprise search solutions.

Critical Security Bulletin: September 2025 Updates

The September Security Bulletin addresses several vulnerabilities discovered across Atlassian’s product suite. While none reached the critical severity level that would trigger an emergency patch, administrators are strongly encouraged to update their instances to the latest versions as part of their regular maintenance schedule.

It’s worth noting that Atlassian maintains a dual-track security update system. Critical vulnerabilities are patched immediately upon discovery, while lower-severity issues are bundled into monthly bulletins. This approach balances security needs with operational stability, allowing organizations to plan their update cycles effectively.

The September bulletin is particularly important given the increased focus on security following the major acquisitions and the broader rollout of AI capabilities across the platform. Organizations should ensure they’re running supported versions to benefit from these security updates.
