Chariot Defense
San Francisco-area startup building tactical-edge power distribution systems (Amphora/Amphora 400) for drones, sensors, electronic warfare, and directed-energy systems on the modern battlefield; emerged from stealth in July 2025 with an $8M seed round led by General Catalyst and XYZ, D3 among the backers.
Chariot Defense is a defense-technology startup, headquartered in South San Francisco, California, building power distribution systems for military platforms operating beyond traditional grid infrastructure. Its Amphora product line delivers modular, high-voltage, low-signature power at the tactical edge: Amphora (24VDC, 5kW, 5kWh) and Amphora 400 (400VDC three-phase, 35kW, 15kWh, aimed at higher-draw uses like air defense, directed energy, medical, and additive manufacturing). A next-generation hybrid platform, Vanguard, promising roughly 10x more power for multi-domain operations, is in development. Founded in late 2024 by CEO Adam Warmoth, who previously led counter-UAS (cUAS) engineering at Anduril Industries and was Head of Product at Archer Aviation, Chariot assembled a team with backgrounds from Tesla, Apple, Anduril, Uber, and Archer. The company emerged from stealth in July 2025 with an $8M seed round led by General Catalyst and XYZ Venture Capital, with D3 among the participating investors alongside Cubit Capital, Ravelin Capital, Forward Deployed VC, Pax, New Vista, and Brave Capital.
