Today, longtime Founders Fund partner Brian Singerman announced on X that he would be taking a step back. He will be transitioning from partner to partner emeritus to get a better “work-life balance,” although he will continue to serve as an “investor and strategic advisor” for the firm.  

Singerman has been at Founders Fund for over 16 years. In his goodbye post, he wrote that he was attracted to the firm, which was launched by Peter Thiel in 2005, because it was considering a “literal moonshot” investment in SpaceX. Singerman went on to invest in companies like fintech Affirm, and health insurance company Oscar Health, both of which went public. 

Singerman isn’t the only partner to step back from the firm this year. In January, Keith Rabois left Founders Fund to join Khosla Ventures.
