Alexandr Wang is the chief AI officer of Meta and co-founder of Scale AI. We talk about the seven-month effort to build Muse, why Meta focused on personal AI agents instead of coding, and how Mark Zuckerberg and Nat Friedman helped shape the product. Alexandr shares how Zuckerberg recruited him after Meta's Llama 4 setback, why he left Scale after nine years, and how he's rebuilding Meta's AI lab around small teams, exceptional talent, and minimal bureaucracy. We also discuss using memes to make a product go viral, the importance of having a single point of view, and why Alexandr believes AI could give everyone the ability to pursue bigger ambitions.

Jeremy Stern is the editor-in-chief of Colossus, where he writes long-form profiles of leading entrepreneurs and investors. He goes behind the scenes of his reporting on Mark Zuckerberg, explaining how months of interviews revealed Zuckerberg’s fascination with Augustus, relentless competitive drive and commitment to building Meta for decades. Jeremy discusses why Meta’s distribution and infrastructure could give it an advantage in AI and why some founders seem incapable of walking away. He explains how a question about defense technology became his first profile, on Palmer Luckey, and why he brings the craft of fiction and poetry to writing about business. Jeremy also describes Scott Wu’s combination of mathematical genius, natural leadership and authenticity, and how Josh Kushner’s family history shaped his exploration of Thrive Capital and the American dream. The conversation closes with the story of Jeremy’s Russian professor, whose belief that people have an obligation to their gifts changed his life and helped shape how he sees the people he writes about.

Alexander Taubman is the co-founder and CEO of Long Lake, a company that buys established service businesses and uses AI to improve how they operate. He explains Long Lake’s $6.3 billion deal for American Express Global Business Travel, why deploying AI in the real economy is difficult and why he sees productivity gains creating more jobs as businesses grow. Alex describes how Nexus, Long Lake’s AI platform, connects models to business data and workflows, why its engineers work alongside employees in the field and why he wants to own businesses rather than sell software. He shares how his grandfather’s idea of “threshold resistance” applies to AI adoption, what he learned at Goldman Sachs and Oaktree and how investing in founder-owned businesses through Taubman Capital prepared him to build Long Lake. Alex also discusses the influence of Danaher, Henry Singleton and John Malone, why he values partners who make him more ambitious and why Long Lake plans to hold its businesses for decades. Including Amex GBT, he expects more than $4 billion in combined revenue the following year and explains why he believes long-term compounding could eventually build a trillion-dollar company.

Ronnie Fieg is the founder, CEO and creative director of Kith. At 13, he turned down an envelope of cash at his bar mitzvah to ask his cousin for a job, then spent 15 years working his way up from stock boy to buyer at David Z. He explains how growing up in Queens and working on 8th Street shaped his taste, how his first ASICS Gel-Lyte III collaboration landed on the front of The Wall Street Journal’s Pursuits section and why he still designs every product for himself first. Ronnie describes why Kith refuses to wholesale or license, why he opens new physical stores as online sales grow and why he believes luxury should mean how much people love what they buy. He also details how a failed white chocolate bread idea became Kith Treats, how he prices product so customers get more than they pay for and what he felt seeing all 1,800 of his shoe designs laid out in chronological order. Ronnie shares how an obsession with padel led to Kith Ivy, why he is expanding into hospitality with Ronnie’s and why growing up before the internet forced him to develop his own point of view.
