"More impressively, Atlassian has never taken a dime of venture capital financing" - that's totally false as they actually did took a few investments, but truth to be told it was years after they were profitable.
All our venture raises were existing employees selling shares. Atlassian (the company) has never taken a dime of venture capital onto the balance sheet.
Also a reason why we're often (in my view) erroneously left off some of the unicorn lists - they only list "venture backed" companies.
