Atlassian is a publicly traded company with a dual-class share structure that concentrates voting power mainly in the hands of its founders, Mike Cannon- Brookes and Scott Farquhar. These two co-founders own the majority of the high-voting Class B shares, giving them control over approximately 88% of the company's total voting power. Additionally, institutional investors such as Vanguard Group, BlackRock, T. Rowe Price Associates, and Baillie Gifford own significant portions of the company. Public and retail investors also hold shares, but with much less voting influence compared to the founders.

Key Ownership Details:

• Mike Cannon-Brookes and Scott Farquhar own nearly all of the Class B shares, which have 10 times the voting power of Class A shares.
• Institutional investors hold roughly 56-78% of the economic ownership, depending on the report.
• Public and retail investors hold remaining shares but have minimal control due to the dual-class voting system.

Leadership:

• Mike Cannon-Brookes and Scott Farquhar are co-CEOs and co-founders, with dominant ownership and voting rights.
• Other executives manage company operations, but voting control remains largely with the founders.

This ownership structure allows the founders to steer Atlassian strategically while being supported by broad institutional and retail shareholder bases.
