Prama Yudhistira
Co-Founder @ Hex Security At Codegen, I built asynchronous coding agents that improved the workflow of developers, and even got non-developers writing production software.

Huzaifa Ahmad
Co-Founder, Hex Security. Previously, I built software at companies like PlayAI, AWS, and Capital One. On the side, I built consumer apps that reached millions of downloads. But I've always loved breaking things just as much as building them. In college, I reverse engineered every major ATS platform and built Talently, a tool that sent over 200K job applications. Now we build AI that hacks before attackers do.
