Mike Cannon-Brookes is an Australian businessman best known for cofounding Atlassian and leading it as CEO. He started the software company in 2002 with Scott Farquhar soon after university, using credit cards to get it off the ground.

Outside software, he has put money into energy and climate projects through Grok Ventures, which he started in 2016.

How Mike Cannon-Brookes built his fortune

Most of Mike Cannon-Brookes’ money comes from Atlassian, the collaboration software company he started in 2002 with Scott Farquhar. The pair launched it soon after graduating and funded the business with credit cards. Atlassian’s first big product was Jira, built for bug tracking, issue tracking, and project tracking. Instead of relying on a traditional sales force, the company focused on product development and sold software through its website at lower prices.

As Atlassian grew, it opened a New York office in 2005 and later moved that U.S. base to San Francisco. The company raised its first outside money in 2010 with a $60 million round from Accel. In 2015, Atlassian debuted on Nasdaq with a market value of $4.37 billion.
