Creating Muse: The Fastest-Growing AI Product Since ChatGPT | Alexandr Wang, Meta

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.

Peter Rahal is the co-founder of RXBAR, David Protein, and Medici Brands. After selling RXBAR for $600 million, he tried investing and quickly discovered he was miserable watching other people run companies. He explains why he returned to protein bars, why founders must deeply understand their products and how he plans to build the most important food company of the 21st century. Peter describes the intelligence, beauty and discipline behind David's brand, how growing up with dyslexia shaped his competitive drive and why he channels anger and resentment into company building. He also details his approach to hiring former founders, building a culture of truth seeking and humility and treating the organization itself as a product. Peter walks through the acquisition of his critical ingredient supplier, Epogee, the supply agreements that protected his business and what he would change about communicating the decision to other entrepreneurs. He shares why he chose Greenoaks as an investor, why speed matters more than maximizing a fundraising valuation and how he is building a decentralized organization where leaders master their products, confront problems and earn their autonomy.

Luca Ferrari is a co-founder of Bending Spoons, the technology company he built with his partners by rethinking how software businesses should hire, operate and allocate capital. He explains why Bending Spoons aspires to build “the best company there ever was,” why it favors raw talent and drive over experience and how a centralized talent team uses testing and more than 100 signals to identify exceptional people early. Luca describes the company’s culture of extreme ownership and relentless simplification, including why employees are given more work than they can possibly complete, why teams rotate across businesses and why Bending Spoons eliminated traditional job titles. He also details the proprietary operating system and AI tools that allow small teams to run acquired products such as Evernote, why Bending Spoons buys businesses to hold and transform rather than sell and how operational excellence gives it an advantage in acquisitions. Luca closes by discussing going public, his approach to negotiation and capital allocation and why he believes logic and rationality are more reliable than blindly following data.

Mati Staniszewski is the co-founder of ElevenLabs, an AI audio company he started in 2022 with his longtime friend Piotr Dąbkowski. He explains how a frustration with poorly dubbed content in Poland led them to build frontier speech technology, why ElevenLabs combines audio research with product deployment and how its focus on voice shapes where the company chooses to compete. Mati also describes the Palantir-inspired operating model behind ElevenLabs: small autonomous teams, a flat organization and forward deployed engineers who work directly with customers and feed what they learn back into the product. He discusses using AI to amplify human potential, helping people who have lost their voices speak again, why imperfections can make AI voices feel more human and his belief that voice will become one of the primary ways people interact with AI. After turning down multiple acquisition offers, Mati says he and Piotr are committed to building ElevenLabs independently and pursuing what they see as a rare opportunity to reshape how humans communicate with technology.

Zach Dell is the co-founder of Base Power, an energy company on a mission to make electricity more affordable and reliable. His starting insight was that home batteries had the wrong business model. Companies sold expensive backup systems that sat idle most of the time. Base installs batteries at homes, retains ownership and operates them as a fleet: charging when electricity is cheap, discharging when it is expensive and providing backup when the grid goes down. The homeowner gets lower electricity bills and backup power. Base gets an asset it can put to work every day. Dell explains why batteries can make the existing grid more efficient, why installing them where people consume electricity helps overcome infrastructure bottlenecks and how Base serves both homeowners and utilities. His strategy is to build a compounding cost advantage through vertical integration and technology. That now includes Base Core, a battery designed and manufactured by the company, and a longer-term ambition to help meet the growing power demands of AI. Dell grew up watching his father, Michael Dell, build a company and knew from childhood that he wanted to become an entrepreneur. After several early ventures failed, he went into investing to study what makes a great business. He describes the “Dad Terminal”—ongoing conversations with his father about strategy, operations and the problems in front of them—and the lessons Base has adopted from former SpaceX employees. Engineers and manufacturing teams work close together, and the entire company organizes around a few clearly defined goals. He also explains the operating habits behind Base: monthly written updates, visible performance dashboards and a physical turtle placed on the desk of the person responsible for resolving a critical bottleneck. He keeps separate notebooks for working in the business and working on it, setting aside time each night to think on paper without distractions. He discusses building a beloved brand in energy, why his co-founder conversations focus on what is going wrong and why Base is his last company. His ambition is a lifelong effort to make, move, store and sell electricity more affordably and reliably.

Doug Leone spent 26 years helping lead Sequoia Capital through successive eras of technological change. Born in Italy, he came to the United States without speaking English and carried the insecurity of an outsider into his career. That fear became fuel: whenever he felt himself falling behind, he forced himself to start over. After stepping down from Sequoia at 65 to make room for the next generation, he returned four years later. Now he considers himself a low-level analyst again, racing to understand an AI revolution that he believes is rewriting business more radically than anything he has seen before. Leone explains the three questions he asks before making an investment: Would he put his children's money into it? If he could make only 20 investments in his life, would this be one of them? Could it return the entire fund? He is interested only in extreme outliers—companies capable of returning 100 times the original investment—and says the biggest mistake venture investors make is selling their winners too early. Sequoia once owned enormous stakes in Apple, Cisco, Google and NVIDIA, but even the greatest investors failed to anticipate how long exceptional companies could continue compounding. His role as an investor is not to shape a founder's technology. It is to help turn a product into a business: recruiting the first team, building sales and marketing, navigating crucible moments and preserving the founder as the soul of the company. He describes backing David Vélez before Nubank existed, what Fred Luddy's unusual ServiceNow pitch revealed about him and why Sequoia looks for the same qualities in founders and its own partners: a hypercompetitive person with a heart of gold. Leone also discusses trust as the accelerant that makes business move quickly. Trust requires both competence and good intentions, and it is earned by helping founders when they are most vulnerable. He explains why founders should architect their boards as carefully as their products, why productive disagreement is different from argument and how to deliver difficult feedback so it can actually be heard. He closes with lessons from his longtime partner Michael Moritz: listen to the exact words people choose, put the other person first and always ask what a company could become if everything goes right.
