Noom CEO: Geoff Cook

November 11, 2026 · 46 min

Show notes

Geoff Cook, CEO of Noom, started microdosing GLP-1 to put himself in the user's shoes. Noom's combined behavior-change-plus-medication GLP-1 programs are now 70% of revenue.

He joins Kyriakos Eleftheriou, CEO of Terra API, to talk about the $500 million Meet Group exit, why most people regain the weight in 18 months, why he wouldn't be surprised if Oura and Whoop start prescribing, why a closed loop is hard for the frontier labs to copy, and a peptide market he'd call a multi-billion-dollar black market.
