David Axmark calls himself an 'accidental entrepreneur'. His driving interest was not building companies but using technology that he liked, and when he found that nobody wanted to hire him to do that he had to start his own company. He worked as a consultant for more than 15 years before concentrating on MySQL, which began development in 1994.
David left the company after it was acquired by Sun in 2008. An avid supporter of the open-source movement, David is now supporting and investing in other open-source ventures.
