Mach Industries

Mach Industries is a Huntington Beach, California defense manufacturer founded in 2023 by CEO Ethan Thornton that builds unmanned military systems—including VTOL drones, long-range strike and counter-UAS—and related propulsion and energetics, aiming for highly integrated hardware that costs less than incumbent contractors. The company operates large California manufacturing footprint and, after acquiring solid-rocket-motor startup Exquadrum, expanded Mach Energetics and Mach Propulsion lines to ease munitions and engine bottlenecks. After a June 2026 Series C of $300 million at a $1.8 billion valuation, Mach raised an additional $600 million Series C extension in September 2026 that doubled its valuation to about $3.7 billion, with Ribbit Capital, Infinite Capital, Bedrock Capital and Sequoia among investors in both tranches, to scale manufacturing and programmes.
