Co-founder and CFO of Castelion, a defense-technology company developing and scaling U.S. hypersonic weapons. He previously led financial planning and government cost proposals for classified programs at SpaceX and was a vice president in Goldman Sachs’ aerospace and defense investment-banking group.

Castelion Raises $1 Billion to Scale Low-Cost Hypersonic Weapons

Castelion’s central challenge is not building a hypersonic weapon but manufacturing thousands of them at low cost, according to co-founder and CFO Andrew Kreitz. The defense startup, valued at $13 billion after raising $1 billion, plans to begin producing its Blackbeard strike system next year while advancing a larger long-range weapon and interceptors. Kreitz says his experience in SpaceX’s finance organization shaped the company’s view that defense-system costs reflect supply-chain choices and customer incentives, not an unavoidable constraint.
