His story is one of ambition, success, and unwavering commitment to ethical leadership. This is the story of Mike Cannon-Brookes, a visionary who blends technology with purpose.
A Humble Beginning: Early Life and Education
Mike Cannon-Brookes was born on November 17, 1979, in New Haven, Connecticut, before moving to Sydney, Australia at a young age. Raised in a well-educated family—his father was a banking executive, and his mother a university lecturer—Cannon-Brookes grew up in an environment that placed a high value on education and intellectual curiosity. From a young age, he was encouraged to think critically and take initiative, laying the foundation for his entrepreneurial mindset.
After attending Cranbrook School in Sydney, Cannon-Brookes went on to study at the University of New South Wales, where he earned a bachelor’s degree in information systems. During his time at university, Cannon-Brookes met Scott Farquhar, a fellow student with whom he would eventually co-found Atlassian, a company that would go on to change the landscape of enterprise software.
From University to Entrepreneurship: Founding Atlassian
In 2002, with just $10,000 in startup capital, Mike Cannon-Brookes and Scott Farquhar co-founded Atlassian, a software company designed to create tools that help teams collaborate and manage projects more efficiently. Their first major products, Jira and Confluence, would go on to revolutionize the way software developers, project managers, and business teams work together. Atlassian’s products quickly became indispensable to development teams, startups, and Fortune 500 companies alike, thanks to their scalability, user-friendly design, and affordability.
One of the most impressive aspects of Atlassian’s rise was that the company achieved significant growth without taking outside investment—a rarity in the startup world. This independence allowed Cannon-Brookes and Farquhar to maintain control over the company’s vision and culture, building a business that prioritized customer needs and employee well-being over external pressures.
By 2015, Atlassian had grown so successful that it went public on the NASDAQ with a valuation exceeding $4 billion. The company’s growth trajectory continued to accelerate, and by the time it was listed, Atlassian had become a dominant player in the enterprise software space, with a market capitalization in the tens of billions. Cannon-Brookes had solidified his place as one of Australia’s top entrepreneurs, and Atlassian’s tools were helping millions of users worldwide to collaborate more effectively.
Climate Advocacy: Using Influence for Global Change
Despite his immense success in business, Cannon-Brookes has never been content with merely accumulating wealth. He has long been an advocate for climate action, using his platform and resources to push for a greener future. Alarmed by the slow response to climate change in his home country of Australia, Cannon-Brookes began leveraging his wealth to support renewable energy projects and advocate for climate policies.
In 2017, he made headlines when he took to Twitter to challenge Elon Musk, the CEO of Tesla, offering support to build the world’s largest lithium-ion battery in South Australia. This challenge resulted in the completion of the project in under 100 days, a major achievement that helped stabilize the region’s energy grid and demonstrated the potential of renewable energy technologies.
This ambitious project was just the beginning of Cannon-Brookes’ involvement in the renewable energy sector. He became a significant investor in clean energy, including backing the Sun Cable project—an endeavor to build the world’s largest solar farm and battery storage facility in Australia’s Northern Territory. The multibillion-dollar initiative also aims to build a submarine cable to supply power to Singapore, providing a model for sustainable infrastructure on a massive scale. By supporting these projects, Cannon-Brookes is helping to reshape regional energy markets and set a precedent for how nations can address the growing demand for renewable energy.
Advocating for Stronger Climate Policies
Along with his investments, Cannon-Brookes has also been vocal in calling for stronger government action on climate change. He has used social media, public appearances, and interviews to advocate for more aggressive climate policies, urging governments around the world to move away from fossil fuels and transition to renewable energy sources. Cannon-Brookes believes that businesses, governments, and individuals all need to play a role in addressing the climate crisis, and he has used his status to champion policies that promote a cleaner, more sustainable future.
His activism extends beyond financial investments. He works tirelessly to educate the public and raise awareness about climate change, often speaking out against the reluctance of governments to adopt more comprehensive environmental policies. Cannon-Brookes is committed to making a meaningful difference, both through his financial investments and his public advocacy.
A Private Life with a Public Purpose
Despite his high profile, Cannon-Brookes leads a relatively private life. He is married to Annie Todd, and the couple has several children. Together, they reside in Sydney, where Cannon-Brookes is known for his down-to-earth demeanor and casual style. Often seen in jeans and a t-shirt, Cannon-Brookes is not one for the extravagant lifestyle that many billionaires embrace.
Outside of his work in tech and climate advocacy, Cannon-Brookes has other diverse interests, including an ownership stake in the Utah Jazz, an NBA team. His passion for basketball is just one of the many facets of his character, showing that his interests extend far beyond the boardroom.
Philanthropy and Giving Back
Philanthropy has played a significant role in Cannon-Brookes’ life. Along with his wife, he established the Dave and Cheryl Cannon-Brookes Foundation, which supports a range of causes including education, renewable energy, and animal welfare. One of the foundation’s most notable initiatives is Maddie’s Fund, an organization that promotes the no-kill movement in animal shelters across the United States. Through their foundation, Cannon-Brookes and his family have donated millions to various causes, demonstrating their commitment to using their wealth for the greater good.
Cannon-Brookes is also a signatory of the Giving Pledge, an initiative that encourages the world’s wealthiest individuals to donate the majority of their wealth to address society’s most pressing challenges. Through this pledge and his other philanthropic efforts, Cannon-Brookes has worked to leave a lasting positive impact on the world.
