Top SchoolStephen Marcus is a venture-backed founder and investor who co-founded and manages Riot Ventures, a Los Angeles–based multi-stage VC that writes checks up to $100M to back deep-technology founders. He combines operator chops—having founded six hardware-plus-software companies scaling wireless carrier footprints—with a track record of early bets in category-defining companies like Okta, Stripe, Toast, and Desktop Metal. Stephen sits on multiple boards across robotics, defense, internet infrastructure, and autonomy, and is active in both campus innovation (MIT Deshpande Center) and angel investing. With an MBA from MIT Sloan and a BS from WPI, he pairs technical intuition with market-building experience, and outside the office pursues high-adrenaline hobbies such as piloting aircraft and high-stakes poker—hints of the risk tolerance that informs his investing style.
