E431: Marty Kausas on AI, Trillion Dollar Startups & Founder Psychology

What if the best reason to start a company isn’t to change the world, but simply because you love the game? In this episode, I sit down with Marty Kausas, CEO of Pylon, to unpack how he thinks about building an ambitious company from first principles. Marty explains why Pylon started with a goal of reaching $1 billion in revenue, why market size can matter more than the quality of the founding team, and why the rise of AI has pushed his definition of a generational company even higher.

What if AI makes talent, not technology, the biggest competitive advantage in private equity? Michael Bruun is Partner and Global Co-Head of Private Equity within Goldman Sachs Asset Management. We break down how Goldman Sachs competes for the best middle-market assets, why Michael believes talent can move the needle more than almost anything else, and how higher rates have forced private equity back to the fundamentals of EBITDA and cash-flow growth. We also discuss how Goldman is implementing AI across portfolio companies, why transformation must start with the CEO, and why the war for exceptional talent may become even more important as every employee becomes AI-enabled.

What if the biggest mistake in venture capital is investing in what already looks like a great venture investment? In this episode, I sit down with Dr. V (Vaibhav Agrawal), Founder ODDBIRD VC, is a San Francisco-based venture investor who spent nearly a decade at Lightspeed, to explore why he believes the traditional venture playbook is changing. Sourcing has become a media and distribution business, companies are staying private longer, and investors increasingly need to think proactively about liquidity rather than simply waiting for their winners to go public.

What if passive investing is actually one of the biggest active forces shaping markets today? In this episode, I sit down with Michael Green, Founder and CIO at Tier1 Alpha Asset Management. Michael challenges the conventional view that stock prices primarily reflect fundamentals, arguing that the transaction itself moves prices and that the rise of passive investing has fundamentally changed who trades, why they trade, and how markets respond to capital flows.

Peter Hecht, Managing Director at AQR Capital Management, explains why diversification has to be measured by underlying risk rather than the number of investments you own. At AQR, diversification is a core principle: thousands of relatively small, uncorrelated investment decisions can collectively create an attractive return for a given level of risk.

What happens when a private equity firm refuses to chase every new opportunity and spends 30 years getting better at one thing? David sits down with Michael Fisch, co-founder and CEO of American Securities, to unpack how the firm grew from a $71.4 million first fund to $23 billion in AUM without abandoning the investment discipline that got it there. Michael explains how private equity evolved from a sub-$1 billion institutional market into a multi-trillion-dollar industry, why American Securities resisted the temptation to expand into every adjacent asset class, and why seeing more deals matters almost as much as knowing which ones to reject.

David sits down with Byron Ling of Twelve Below to unpack the judgment required to invest at the earliest stages of technology. After roughly 30,000 founder meetings over the past decade, Byron believes the strongest signals rarely appear on a résumé. He looks for an almost biological drive to win, second-level thinking, exceptional learning velocity, clear communication, authenticity, and a sense of urgency that makes a founder difficult to compete against.

What can 32 years as a university CIO teach you about identifying exceptional investors before everyone else does? David sits down with Scott Malpass, Co-Founder and Managing Partner of Grafton Street Partners and former Chief Investment Officer of the University of Notre Dame, to discuss the patterns he learned from evaluating thousands of investment firms and building decades-long relationships with some of the world’s leading managers.

David sits down with Bryon Hargis, co-founder of Castelion, to unpack why rebuilding America’s defense manufacturing capacity has become a national security imperative. Bryon explains why decades of consolidation and outsourcing weakened the defense industrial base, why America could struggle against an adversary with significantly greater manufacturing capacity, and why Castelion is betting that deterrence ultimately requires weapons that can be produced affordably by the thousands.

Why do so many GPs misunderstand what institutional LPs actually care about? David sits down with John-Austin Saviano, an Backing & Building Challenger Investment Firms and Former Endowment CIO, argues that one of the biggest mistakes GPs make is overemphasizing track record. Great LPs care less about the headline returns than how those returns were generated. They want to understand the investment process, whether it is repeatable, and whether the people and market conditions that produced past performance still exist today.
