Atlassian Corp's rise to a record on Friday has catapulted its two Australian co-founders onto the Bloomberg Billionaires Index.

The fortunes of co-chief executives Michael Cannon-Brookes and Scott Farquhar have risen $US1.1 billion in 2018 to $US4.1 billion ($5.2 billion) apiece, making them the 499th and 500th richest people on the planet.

Atlassian makes work-collaboration products like HipChat and Trello, which it bought for $US425 million last year. The Sydney-based company saw billings grow 43 per cent in the three months ending December 31, helping its share price jump by a third so far this year. The business, which has more than 100,000 customers, did not have a sales force and preferred to rely on word of mouth to generate sales, Mr Farquhar said in February.

The pair, who founded Atlassian in 2002, have become figureheads for Australia's tech scene and they're already used to rubbing shoulders with billionaires. Last year, Mr Cannon-Brookes lost a high-profile bet with Tesla Inc's Elon Musk over the installation of the world's largest lithium battery in South Australia.
