Casey Winters is a longtime and legendary advisor and operator. He’s worked with companies like Airbnb, Faire, Canva, Whatnot, Thumbtack, Tinder, and Reddit and until recently was the Chief Product Officer at Eventbrite, where he managed the PM, design, research, and growth marketing teams. Before Eventbrite, he led growth and product teams at Pinterest and Grubhub. In today’s episode, we discuss what Casey calls the “zero interest rate phenomenon” product manager and how to avoid becoming one. He provides valuable insights on thinking outside popular frameworks, shipping products efficiently, and avoiding overreliance on user research. We explore the three types of network effects, how to leverage them, and how to break someone else’s network effect. Finally, Casey shares his contrarian approach to interviewing product managers and his thoughts on the future of PM roles with AI.
