Mach Industries was founded by then-19-year-old Ethan Thornton (MIT dropout) and develops hydrogen-fueled defense platforms including the Stratos balloon system and a portfolio of glide and loitering munitions. Public reports peg the company near $470M valuation in early 2026 after a Series B led by Bedrock; some later reports suggested a multi-billion-dollar Series C is being discussed but is unconfirmed. Holds multiple DoD contracts.
