About
Se Yong Park is a co-founder of fomo, the social-first crypto trading app that raised a $75 million Series B led by Index Ventures in June 2026 at a $550 million valuation — about a year after launch, and on the back of a first round funded by 140 angel investors rather than a seed fund. He read economics at Yale and started out in investment banking at Deutsche Bank, where he met his future co-founder Paul Erlanger; the two have now worked together for roughly five years across banking, dYdX and fomo. Park moved to crypto to lead the build of dYdX's core trading product through the growth of decentralised perpetual futures, then ran ecosystem at Eclipse Labs before starting fomo with Erlanger and Prashan Dharmasena. His argument for the product is that trading is a fundamentally social act and an expression of insight — which is why fomo pairs execution with a public feed, leaderboards and visible positions rather than hiding them.
Beyond investing
- Founded
- Co-founded fomo in 2024 with Paul Erlanger and Prashan Dharmasena, all three out of dYdX; the app launched publicly in May 2025.
- More
- Led the build of dYdX's core trading product during the growth of decentralised perpetual futures markets. Has worked with Paul Erlanger for roughly five years, first at Deutsche Bank and then at dYdX, before the two started fomo. Ran ecosystem at Eclipse Labs between dYdX and fomo. Earned a BA in economics from Yale University. Pitched roughly 200 dream angel investors alongside Erlanger instead of raising a seed round; 140 of them invested, and fewer than a handful of the ones who took the call said no. Points to fomo shipping without gas fees as the reason mainstream holders stay — the app charges a 0.50% transaction fee and absorbs blockchain gas costs.
