About

Bryon Hargis co-founded Castelion in November 2022 with two SpaceX colleagues to apply commercial-rocket production discipline to the long-range strike weapons the U.S. military is running short on. At SpaceX he led sales and business development for the company's National Security satellite programs, building a multi-billion-dollar pipeline in under five years. He is a 20-year veteran of the aerospace and defense industry and holds an M.S. in Applied Physics from Johns Hopkins and a B.S. in Mechanical Engineering from Georgia Tech. Castelion has raised more than $350 million to mass-produce hypersonic missiles in the U.S. industrial base and now holds programs of record across the Army and Air Force.
