Daniel Naim
Daniel Naim is the founder and CEO of Fennel, a mobile investing app that hands everyday retail investors the ESG data and shareholder-voting power that big institutions usually keep to themselves. A former dark-matter physicist who grew up in Beirut and earned a physics PhD at UC Davis, Naim left the lab in 2020 - watching California burn and Engine No. 1 win an Exxon board fight - convinced that capital markets, not particle detectors, were the most pressing problem he could work on. Fennel refuses payment for order flow, won't lend out users' shares, became a certified B Corp, and was named one of Fast Company's most innovative companies in personal finance.
Scott Stephenson
Scott Stephenson is the co-founder and CEO of Deepgram, the voice AI company building foundational speech-to-text, text-to-speech, and voice agent models from scratch. A particle physicist who once helped build a dark-matter detector two miles underground, he now runs an AI company used by NASA, Spotify, and Twilio.
