David George is a General Partner at Andreessen Horowitz, where he leads the firm's growth fund. Before a16z, David was a General Partner at General Atlantic. He has been involved in investments including Databricks, Ramp, Harvey, and Figma. We discussed David's framework for thinking about the AI buildout: why the thesis that "it's all going to work" is the right one, and why the answer to almost every question in AI right now is "and" rather than "or." We got into where we actually are in the diffusion of AI into the enterprise, why there are 1.5 billion knowledge workers that AI has barely touched, and what would have to be true for the buildout not to continue. David shared his framework for thinking about product cycles vs. capital cycles, why right now is a 9 or 10 out of 10 on the product side, and why autonomous driving and robotics are massively underappreciated. We also talked about why vibes and narrative matter more than ever for founders, why he never shorts a messianic founder or a product people love, and how he thinks about the scale and ambition of Andreessen Horowitz as a firm.

Andrew Feldman is the co-founder and CEO of Cerebras Systems, the AI chip company he founded in 2016 around a single radical insight: that winning in compute requires not incremental improvement but a fundamentally different architecture. Cerebras is the creator of the world's largest chip, the Wafer Scale Engine, and counts the US government, sovereign cloud providers, and OpenAI among its customers. Alongside Eric Vishria from Benchmark, we discussed why Andrew believes that if you are going to attack Goliath, being 10% or even twice as good is not an available strategy and you have to aim for 100x or 500x better. Andrew walked through Cerebras's near-death experience: 18 months of board meetings where the only thing to report was "still can't make it," spending $8 million a month, and what kept the team going. He explained how we go from sand to a ChatGPT answer and why the US semiconductor supply chain is in a precarious position. Andrew shared what most people get wrong about what makes Nvidia great (it’s not CUDA), and why he thinks of himself as a professional David in an ongoing battle with Goliath.

Brian Singerman is the co-founder of GPx, a fund launched in 2025 alongside Lee Linden of Quiet Capital. GPx backs elite emerging managers at the early stage, then provides programmatic capital to co-lead later-stage investments when those managers choose to bet their career on a breakout company. Before GPx, Brian was a General Partner at Founders Fund for over a decade, where he was involved in investments including Anduril, Stemcentrx, and Airbnb. He transitioned to Partner Emeritus at Founders Fund in December 2024. We discussed Brian's framework for identifying outlier founders, why he has no checklist, no rubric, and no list of attributes, and why he is always looking for the single thing someone is genuinely better at than anyone else. Brian walked through the Anduril founding team as a case study in complementary spikes, explained what Peter Thiel is actually best at as a venture capitalist, and broke down how Founders Fund made the second most money on Airbnb despite being the 30th investor. We also got into GPx's strategy, why Brian thinks SPVs are dead, his framework for the optimal LP allocation to venture, and when to make a concentration bet.

Tony Xu is the co-founder and CEO of DoorDash, the leading local commerce platform in the United States.

Sam Blond is the co-founder and CEO of Monaco, an AI-native revenue automation platform built to replace the CRM as the system of record for sales. Before Monaco, Sam was a Partner at Founders Fund and before that one of the most accomplished go-to-market executives in the tech industry, having served as VP of Sales at EchoSign (acquired by Adobe), VP of Sales at Zenefits, and Chief Revenue Officer at Brex.
