What happens when AI agents scale faster than their economics can support? In this episode of Built Not Born, host Sage Nye sits down with EON co-founders Ki-youn Jung, Co-founder and CEO, and Abhishek Singh, Co-founder and CTO, to explore the infrastructure challenges emerging as enterprises adopt AI agents at scale. They discuss how EON’s experience with escalating compute costs led them from a health-tech application toward building an inference layer designed to anticipate agent behavior, reduce redundant token usage, and lower latency. The conversation examines why token economics could undermine traditional SaaS models, how reusable and deterministic AI outputs can preserve trust through statistical verification, and why infrastructure may represent the bigger opportunity in AI. They also explore the challenges of running agents for weeks or months, including drift, oversight, and maintaining alignment. The episode offers a practical look at building infrastructure for the next era of computing.
