Andrew Mann
Founder
Andrew is a serial entrepreneur with the unfortunate habit of asking “Wouldn’t it be great if…” The spark for 9-ON came from two experiences that never left him: Harkness-table discussions in high school featuring small groups around an oval table where everyone could see everyone else and really engage with each other peer to peer—and, during the pandemic, Dr. Greg Salyer’s extraordinary open-invitation philosophy salon, where a small gathering of previously strangers met online biweekly, and over time were drawn together in real connection. Wouldn’t it be great if there were an enormous online directory of reading and discussion groups just as compelling as this one was—and always on so that you can find a group whenever you wanted from the comfort of your own home? Before 9-ON, Andrew founded DentBetty, an online consumer marketplace for car repair, and Common Object, a B2B SaaS platform. He also previously co-managed Eureka Capital Management, a hedge fund and venture firm investing in leaders of emerging trends; and began his career as a research associate at Fidelity Capital Management. He holds a CFA, and a BA in Government from Harvard.
