Mike Cannon-Brookes: Atlassian CEO, Net Worth, NBA Ties

Mike Cannon-Brookes co-founded Atlassian in 2002 with a $10,000 credit card and turned it into a company now used by over 43,000 organizations worldwide. He’s also the kind of billionaire who quietly bought a stake in the Utah Jazz while serving as one of Australia’s most influential voices on clean energy.

Five key facts anchor this profile: birth date, CEO transition, ownership stake, peak net worth, and the Utah Jazz connection.

Which NBA team does Mike Cannon-Brookes own?

Cannon-Brookes holds a minority stake in the NBA’s Utah Jazz, partnering with Qualtrics co-founder Ryan Smith on this sports investment. While exact ownership percentage remains unreported, his involvement places him among a select group of tech billionaires with NBA holdings. The broader group of four billionaires in the NBA includes names like Joe Tsai (Alibaba, Brooklyn Nets) and Steven Ballmer (former Microsoft CEO, LA Clippers).

Utah Jazz connection

Beyond the Jazz stake, Cannon-Brookes maintains sports investments closer to home. He holds an interest in the South Sydney Rabbitohs, an NRL franchise based in Sydney. His Grok Ventures portfolio has also touched other sports-related opportunities, though detailed holdings beyond the two named teams remain private. The Utah Jazz connection aligns with his broader investment thesis: backing established franchises with strong regional ties.

Other sports investments

The Rabbitohs represent Cannon-Brookes’ most visible domestic sports play. Unlike his Utah Jazz stake where partnership with Ryan Smith was publicly noted, his Rabbitohs involvement details remain less publicized. The pattern suggests a preference for co-investment structures with other high-profile entrepreneurs rather than sole ownership models.

What this means: His sports portfolio spans two continents and represents a fraction of total wealth, but signals continued interest in tangible assets outside tech.

How Did Mike Cannon-Brookes Make His Money?

Cannon-Brookes built his fortune through a single, concentrated bet: Atlassian stock. Unlike diversified billionaires, his wealth swings directly with the company’s share price—a $7.2 billion drop in 2024 illustrates the risk of that approach.

Atlassian founding

He co-founded Atlassian with Scott Farquhar in 2002 using a $10,000 credit card. Their early target was modest: generate $48,000 annually per founder, roughly matching graduate salaries. The company grew organically without traditional sales or marketing, relying instead on product-led growth that became a Silicon Valley playbook. Atlassian redomiciled from Australia to the United States in 2022, a move that shifted the billionaire’s tax residency profile.

Company growth

Atlassian now serves over 43,000 organizations including Citigroup, eBay, and NASA. The company employs more than 5,000 people with a market capitalization exceeding $50 billion. Cannon-Brookes owns approximately 20% of the company through super-voting shares, giving him outsized control relative to his economic stake. His 53,655 shares were valued at over $10 million as of June 2025 per GuruFocus insider data. As sole CEO since September 2024, he now steers the company without co-CEO Farquhar for the first time.

The catch: Nearly all his wealth sits in one stock. When Atlassian dropped 76% from its peak, his net worth halved. Diversification would reduce volatility but would require selling shares—and founders rarely do that willingly.

What degree does Mike Cannon-Brookes have?

Cannon-Brookes earned a Bachelor of Commerce in information systems from the University of New South Wales. He initially studied computer science at UNSW before making the pivot to commerce—then dropped out to pursue Atlassian full-time.

Education background

His UNSW connection extends beyond graduation. He serves as an adjunct professor and chairs the Computer Science and Engineering Industry Advisory Board at the university, maintaining active ties to his alma mater. This academic involvement is notable for a CEO of his wealth level—many successful founders distance themselves from formal education structures. His unconventional path (studied, left, succeeded) contrasts with some billionaire narratives that emphasize dropping out entirely, yet he returned to formal engagement with academia.

The pattern: Education provided the foundation, but his actual career launch came through risk-taking, not credentials.

How did Atlassian become so successful?

Atlassian succeeded through what became known as the ” Atlassian Way”—a philosophy built on extreme transparency, minimal hierarchy, and product-led growth without sales teams. Their 2002 founding came during the post-dot-com crash period, a time when cautious spending defined tech startups.

Unconventional strategies

Atlassian famously published their “Conference Room Principles” publicly, laying out rules like “The boss always sits in the back row” and avoiding internal PowerPoint presentations in favor of written documents. Their no-sales-model approach meant customers found and bought products organically—radical for enterprise software. This philosophy extended to their IPO strategy: they went public in 2015 at $21 per share, raising minimal capital compared to typical tech IPOs.

Key milestones

The company’s trajectory shows acceleration: first appearing on the BRW Young Rich List in 2007, winning Australian IT Professional of the Year in 2004, then Australian Entrepreneur of the Year in 2006 (youngest recipient ever at the time). The Forbes Global Game Changers list recognized him in 2017, and the Australian Financial Review named him Business Person of the Year in 2016 alongside Farquhar. World Economic Forum designation as Young Global Leader in 2009 added international validation.

What this means: Atlassian’s success wasn’t about groundbreaking technology—it was about building systems that scaled without bureaucracy.

What books has Mike Cannon-Brookes recommended?

Cannon-Brookes maintains an active reading list that he shares publicly, including recommendations updated through 2025. His picks skew toward business strategy, technology history, and systems thinking.

Updated recommendations

His notable recommendations include titles spanning clean energy strategy, organizational design, and technology history. The Sun Cable project involvement signals genuine interest in energy transition—not performative ESG. When founders read widely, their investment thesis often reflects the ideas absorbed, and Cannon-Brookes’ clean energy bets align with reading patterns visible in his public endorsements.

The implication: His portfolio choices (Sun Cable, AGL investment) likely reflect deep reading on energy systems, not casual diversification.

His wealth took a hammering in 2024, but it’s because his fortune comes almost entirely from his Atlassian shareholding.

— AB Mag on wealth volatility

For Australian tech workers weighing their equity compensation strategies, Cannon-Brookes’ story offers a sharp lesson: founder-level wealth concentration creates enormous upside in bull markets but devastating drawdowns when the story changes. Unlike diversified executives, he never sold enough shares to build a buffer—his confidence in Atlassian proved absolute, even when markets disagreed.
