Two Australian students raised $10,000 on a credit card, built software collaboration tools, and spent the next decade refusing to hire a sales team. That decision — product-led growth before anyone called it that — created a $25 billion company with 13,813 employees and $5.2 billion in FY2025 revenue. Atlassian's founding story is a case study in what happens when you trust that engineers will find good software and tell each other about it. Mike Cannon-Brookes and Scott Farquhar met at the University of New South Wales and launched Atlassian in 2002 in Sydney. The first product was Jira, a bug-tracking tool for software developers. They priced it at $10 per user — cheaper than any comparable enterprise software — posted it online, and waited for developers to find it. They did. By 2005, Atlassian reached $1 million in annual revenue without a single salesperson. By 2010, they raised $60 million from Accel Partners to fund growth they had already achieved organically. The Jira and Confluence combination — issue tracking and team documentation — became the default operating system for software development teams at thousands of companies worldwide. Every team that adopted Jira eventually needed Confluence to document the work. Every team that adopted Confluence wanted Jira to track it. The products created switching costs measured not in dollars but in organizational memory embedded in the platforms. The FY2025 revenue of $5.2 billion came almost entirely from subscriptions, with cloud revenue representing 67% of total. The company has reported a GAAP net loss in every year since 2016 while generating over $1.4 billion in annual free cash flow — a divergence that reflects stock-based compensation and amortization of acquired technology rather than cash consumption. The Rovo AI assistant and the Teamwork Graph data layer represent the next strategic bet: if AI can navigate an organization's entire knowledge base across Jira, Confluence, and connected tools, the switching costs become even more severe.
