Host Michael Sonnenfeldt sits down with Joe Neiman, a serial entrepreneur in the automotive technology space and 2X exited co-founder of ACV Auctions and DealerClub, digital marketplaces that transformed the wholesale vehicle industry. Starting as a car dealer, Joe built ACV into a category-defining powerhouse that scaled to over 50,000 cars sold per month and reached a $5B+ market cap. In 2024, he founded DealerClub, which was acquired just 3 months after launch. Joe has built his career by deeply understanding operator pain points and rethinking how markets function at scale.

Joe also shares candid reflections on the personal evolution behind his success—how early experiences with fear and uncertainty became a driving force for growth, and how learning to challenge limiting beliefs shaped both his leadership and decision-making. The conversation explores Joe's "know better" philosophy, leadership transitions from control to influence, and the importance of introspection, family, and health. Joe also discusses his approach to learning, navigating high-stakes environments, and building a life that balances ambition with long-term well-being.
