We build products that make the future feel obvious.
Fun Management creates category-defining products from zero to scale.
Fun Management is a venture studio founded by Sergiu Biris, a serial entrepreneur with more than 20 years experience and previous successful exits such as LiveRail, a company acquired by Facebook in 2014 for $500M.
We build, launch, and grow technology companies with high-velocity execution, design excellence, and go-to-market clarity.
Small teams. Fast cycles. Product–market obsession.
