Ben Horowitz on How a16z Was Built

What exactly is an AI agent, and how will agents change the way we work? In this episode, a16z general partners Erik Torenberg and Martin Casado sit down with Aaron Levie (CEO, Box) and Steven Sinofsky (a16z board partner; former Microsoft exec) to unpack one of the hottest debates in AI right now. They cover: -Competing definitions of an “agent,” from background tasks to autonomous interns -Why today’s agents look less like a single AGI and more like networks of specialized sub-agents -The technical challenges of long-running, self-improving systems -How agent-driven workflows could reshape coding, productivity, and enterprise software -What history — from the early PC era to the rise of the internet — tells us about platform shifts like this one The conversation moves from deep technical questions to big-picture implications for founders, enterprises, and the future of work.

Marc Andreessen, cofounder Andreessen Horowitz, joins the Hermitix podcast for a conversation on AI, accelerationism, energy, and the future. From the thermodynamic roots of effective accelerationism (E/acc) to the cultural cycles of optimism and fear around new technologies, Marc shares why AI is best understood as code, how nuclear debates mirror today’s AI concerns, and what these shifts mean for society and progress.

Housing and healthcare make up nearly half of household spending, yet both sectors are riddled with inefficiency and rising costs. In this episode, Erik Torenberg is joined by a16z Growth partner Alex Immerman and Minna Song and Tony Stoyanov, cofounders of EliseAI, to discuss why they’re tackling these critical industries and how AI can transform everything from leasing and maintenance to patient scheduling and compliance. The conversation covers: Why the U.S. is 5 million housing units short — and how technology can help unlock existing supply How automation can cut waste, reduce labor costs, and improve affordability What fully autonomous buildings might look like, and how that model could extend to healthcare This is about the costs that touch every household, and the role AI might play in finally bringing them down.

Do tariffs help rebuild American manufacturing or hold it back? In this episode, American Compass founder and chief economist Oren Cass sits down with commentator and author Noah Smith and a16z General Partner Erik Torenberg for a lively debate on the future of U.S. industry. They discuss the case for tariff-driven re-industrialization versus free-market approaches, the role of allies in trade policy, and what the numbers really show about manufacturing jobs, investment, and output. Along the way, they challenge each other’s assumptions and explore what it would take to actually bring more production back to American soil.

The AI hardware race is heating up, and NVIDIA is still far ahead. What will it take to close the gap? In this episode, Dylan Patel (Founder & CEO, SemiAnalysis) joins Erin Price-Wright (General Partner, a16z), Guido Appenzeller (Partner, a16z), and host Erik Torenberg to break down the state of AI chips, data centers, and infrastructure strategy. We discuss: - Why simply copying NVIDIA won’t work, and what it takes to beat them - How custom silicon from Google, Amazon, and Meta could reshape the market - The economics of AI model launches and the shift toward cost efficiency - Infrastructure bottlenecks: power, cooling, and the global supply chain - The rise of AI silicon startups and the challenges they face - Export controls, China’s AI ambitions, and geopolitics in the chip race - Big tech’s next moves: advice for leaders like Jensen Huang, Sundar Pichai, Mark Zuckerberg, and Elon Musk
