325: Beyond tokens—applied cryptography for defense, healthcare, and AI

Ismael (Founder/CEO) and Nate (Defense GTM) from Lagrange explain why the biggest commercial demand for cutting-edge cryptography might be outside crypto—securing AI in defense, healthcare, and regulated finance. We cover: why they built DeepProof (a zero-knowledge ML library that proves model outputs over private inputs), how this fits the DoD’s zero-trust mandates, and why frontier crypto R&D should serve national interest, not just faster token launches. We also dig into GTM with government, what zero-knowledge adds beyond TLS, and how to talk “applied cryptography” without getting stuck in a “crypto” stigma.
