Mike Cannon-Brookes: Rebuilding Atlassian for the AI Era After Two Decades of Founder-Led Growth
Mike Cannon-Brookes’ leadership story has entered a new phase. Atlassian’s investor materials identify him as CEO and co-founder, noting that he co-founded the company in 2002, served as Co-Chief Executive Officer from October 2002 to August 2024, and became sole Chief Executive Officer in September 2024.
That transition matters because Atlassian was long defined by the partnership between Cannon-Brookes and Scott Farquhar. The company’s move to a single-CEO structure has made Cannon-Brookes the clearest executive owner of its next chapter. The current Atlassian is not just the Jira and Confluence company of its early years; it is trying to define what it calls the “system of work” for enterprises, with AI increasingly central to that vision.
Under Cannon-Brookes’ current leadership, Atlassian has continued to grow at significant scale. In fiscal 2025, the company said it delivered more than US$5.2 billion in revenue, generated more than US$1.4 billion in free cash flow, and reached 2.3 million AI monthly active users. In Q1 FY26, revenue rose 21% year over year to US$1.433 billion, while cloud revenue reached US$998 million, up 26%, and AI monthly active users surpassed 3.5 million.
Those figures are important because they show Atlassian navigating the difficult transition from its historic self-serve, developer-centric growth model into a larger enterprise platform business. Atlassian has spent years moving customers from server products to cloud and data centre offerings, while expanding beyond software teams into IT service management, work management, video collaboration, developer intelligence and AI-assisted search and automation.
The company’s AI push is now central to Cannon-Brookes’ current role. Atlassian’s Q2 FY26 results highlighted its first-ever US$1 billion cloud revenue quarter and said Rovo surpassed 5 million monthly active users. In Q3 FY26, Atlassian said it continued to add millions of monthly active users to Rovo, AI credit usage was growing more than 20% month over month, and customers using Rovo were growing annual recurring revenue at roughly twice the rate of those not using it.
That is strategically significant because Atlassian’s advantage in AI is not simply model performance. It is context. Jira, Confluence, Bitbucket, Trello, Loom and related tools sit inside the daily workflow of software, product, IT and business teams. If Atlassian can use that context to make AI useful inside real work, Cannon-Brookes has a credible path to making the company more valuable in the AI era rather than less.
Recent acquisitions show how aggressively he is pursuing that strategy. Atlassian completed its acquisition of Loom in 2023 for approximately US$975 million, adding asynchronous video communication to its collaboration stack. In 2025, it entered into an agreement to acquire The Browser Company, maker of Dia and Arc, for approximately US$610 million, positioning the browser itself as a future surface for AI-powered knowledge work. It also agreed to acquire DX for approximately US$1 billion in cash and restricted stock, aiming to bring developer-productivity intelligence into the Atlassian platform.
Those acquisitions say a lot about Cannon-Brookes’ current leadership. Atlassian is not treating AI as a feature layer on top of Jira. It is trying to own more of the surfaces where work happens: issues, documents, service workflows, engineering systems, video communication and even the browser. That is a bigger strategic canvas than Atlassian has historically occupied.
The roots of that ambition go back to the company’s earliest days. Atlassian’s own company history describes Cannon-Brookes and Farquhar as two university friends who started the company in 2002 with a credit card and a desire to build a workplace where they did not have to conform. Their first major success came from Jira, followed by Confluence, and the company grew for years with an unusually product-led, low-friction sales model.
That early model was one of Atlassian’s defining innovations. At a time when enterprise software was often sold through heavy sales teams and long procurement cycles, Atlassian built a business around transparent pricing, online distribution and products that developers and teams could adopt directly. That helped the company grow globally from Australia without following the standard Silicon Valley enterprise-sales playbook.
A major outcome came in 2010, when Atlassian raised US$60 million from Accel after years of bootstrapping. The company then listed on Nasdaq in 2015, with a market capitalisation of approximately US$4.37 billion at IPO. Those milestones turned Atlassian into one of Australia’s most important technology success stories and made Cannon-Brookes and Farquhar global examples of Australian software founders who could build for international markets from Sydney.
Atlassian’s acquisition history also shows how Cannon-Brookes has repeatedly widened the company’s platform. The purchase of Trello in 2017 moved Atlassian further into lightweight visual work management. Opsgenie strengthened incident management. Loom added video communication. The Browser Company and DX now point toward AI-native knowledge work and engineering intelligence. The pattern is clear: Atlassian keeps expanding from software teams into broader collaboration and work systems.
Cannon-Brookes is also a prominent climate and energy figure, which complicates and broadens his leadership profile. Outside Atlassian, he has become known in Australia for clean-energy advocacy and investment, including involvement with large-scale renewable energy initiatives. That public role is not the core of his Atlassian operating performance, but it does shape how he is perceived: not just as a software founder, but as a technology leader willing to use capital and influence in national debates.
What makes his current chapter especially interesting is the pressure of reinvention. Atlassian is no longer a scrappy Australian start-up surprising the world. It is a large public company that must keep growing while defending its relevance against Microsoft, ServiceNow, GitHub, Notion, Slack, AI-native start-ups and others. Cannon-Brookes’ task as sole CEO is to preserve Atlassian’s product-led DNA while making it enterprise-grade enough for the world’s largest organisations.
That is a difficult balance. Too much enterprise complexity could dull Atlassian’s original appeal. Too much attachment to the original model could limit its ability to compete in AI-driven enterprise software. The current strategy — enterprise, AI and system of work — is Cannon-Brookes’ answer to that tension.
