Manage episode 505730954 series 3586436
In this episode of Second Acts, Krish is joined by Reforge’s founder and CEO, Brian Balfour.
Brian dives into: early years of Reforge’s breakout—“the strongest PMF I’d ever felt”—education business, what led to their recent AI-native second act, launching a whole suite of products within a couple of quarters as a lean team, what real-world enterprise adoption requires, retention laws, the emerging breaking points in the Four Fits to $100m, why AI monetization strains past SaaS growth models and is still being figured out (and why people are wrong about Cursor and others), startup-within-a-startup lessons from HubSpot, Izzy the Inventor, and much more.
