The Token Budget Problem Nobody Is Talking About (Matan Grinberg, Co-Founder & CEO of Factory)
retained text
“There are a lot of people that are going out there and saying things like, ‘all jobs are going away,’ or ‘we're going to automate everything,’ or this language about the permanent underclass. And it really upsets me because not only is it inaccurate, but it's really harmful to the psychology of a lot of people that I think have a very important role to play in the future of humanity.” – Matan Grinberg Listen or watch now on YouTube, Spotify, or Apple Podcasts Matan Grinberg is the co-founder and CEO of Factory, an AI company valued at $1.5 billion that helps enterprises like Nvidia, Morgan Stanley, and Adobe automate software development through “Droids,” intelligent agents designed to streamline software engineering. Before Factory, Matan spent more than a decade in theoretical physics, studying string theory at Princeton and UC Berkeley. His work now centers on a different kind of complex system: how software gets built in an era of increasingly capable AI agents, open models, and shifting compute economics. In our conversation, we explore: How Emmy Noether’s theorem continues to shape Matan’s approach to technology, business, and AI Why Matan believes there will always be more problems to solve, even as AI becomes more capable The resource allocation problem facing CEOs as they balance headcount, compute, and token budgets Why Factory is betting on model independence and Matan’s take on the SpaceX-Cursor deal Why Matan pushes back on conflating open models with “Chinese models” and wants a stronger open-model ecosystem The identity crisis that followed Matan’s decision to leave physics Lessons from Factory’s first few years, including learning to push back and identify gaps in his own knowledge Factory’s culture, values, and Matan’s partnership with co-founder Eno Reyes Thank you to the partners who make this possible .tech domains: An identity for builders at their core. Brex: The intelligent finance platform. Persona: Trusted identity verification for any use case.
