Hadrian - Manufacturing the Future
Hadrian is building autonomous factories that help aerospace and defense companies manufacture rockets, satellites, jets, and ships up to 10x faster and up to 2x cheaper. By combining advanced software, robotics, and full‑stack manufacturing, we are reinventing how America produces its most critical parts. We recently raised $260 million in Series C to accelerate this mission.

We work with startups, Tier 1 and Tier 2 suppliers, and major defense contractors across space, shipbuilding, and aviation to scale production, reduce costs, and accelerate delivery on mission‑critical programs. We are backed by leading investors including Lux Capital, Founders Fund, and Andreessen Horowitz.
