Chariot Defense
Chariot Defense is a South San Francisco defense-technology company building hybrid-electric power systems for the battlefield. Its Amphora platform delivers quiet, high-density, software-controlled power to distributed military hardware - drones, sensors, radios, electronic-warfare and directed-energy systems - so that energy never becomes the limiting factor in a fight. Founded in 2024 by former Anduril and Archer engineer Adam Warmoth, the company raised a $34M Series A led by Andreessen Horowitz in February 2026, bringing total funding to roughly $41-42M, and has fielded its systems with the U.S. Army and the Defense Innovation Unit.
