Scott Farquhar (born December 1979) is an Australian businessman who is the co-founder and the former co-chief executive officer of software company Atlassian.

Farquhar often carries the epithet of accidental billionaire after he and his business partner Mike Cannon-Brookes founded Atlassian with the aim to replicate the A$48,500 graduate starting salary typical at corporations without having to work for someone else.

[11] In 2001, Mike Cannon-Brookes sent an email to his University of New South Wales classmates asking if any of them was interested in helping him launch a tech startup after graduation,[12] and Farquhar was the only one who responded.

[17] They decided to forgo the expense of hiring sales people, and instead spent their time and money on building a good product and selling it at a more affordable price via the Atlassian website.

[22] On 26 April 2024, Farquhar announced that he would resign as joint CEO of Atlassian at the end of August to focus on family time, philanthropy, and furthering the global technology industry.

[31][32][33] Farquhar has mentored through the Australian Businesswomen's Network and gives guest lectures on entrepreneurship to MBA students and undergraduates at the University of New South Wales, his alma mater.

[34] In 2014 Farquhar co-founded Pledge 1%, a movement that encourages companies to dedicate 1% of equity, 1% of employee time, 1% of product and 1% of profit to charity.

This was subsequently sold on 4 October 2024 for A$130 million[39] The Point Piper home set on 6,986 square metres (75,200 sq ft) had been in the ownership of the Fairfax family since 1891 and was vacant for nearly twenty years prior to its purchase by Farquhar.
