About
Glenn Case co-founded Hermeus in 2018 and serves as Chief Technology Officer, with primary responsibility for the company's turbojet-to-ramjet propulsion architecture. Before Hermeus he was Technical Director at Generation Orbit and held propulsion engineering roles at NASA and Blue Origin, contributing to liquid-rocket-engine programs across the public and commercial sectors. His core thesis with Piplica was that combined-cycle propulsion was finally tractable for a venture-backed startup and that the U.S. could not afford to cede Mach 5+ flight to China or Russia. He directs Chimera engine development and the broader Hermeus propulsion roadmap.
