Building superintelligence inside a company isn’t about adding AI as a feature. It’s about making it the operating system the whole organization runs on. In this episode of the Lightcone, we sat down with YC’s Pete Koomen to talk for the first time about how he led the effort to build YC’s internal agent infrastructure from the ground up. We cover how giving agents unrestricted access to one database changed everything, the self-improving skill loops that get smarter overnight and why he thinks we’ve arrived at the personal computer moment for AI.
