Value proposition
Chariot Defense builds deployable, software-defined power systems (Amphora platform) that sense, prioritize, and route power across mission-critical military systems in real time, replacing noisy diesel generators with silent, low-thermal-signature, high-voltage hybrid-electric power for the tactical edge.
Products and solutions
Amphora Edge Power family: Amphora (24 VDC, 5 kW, 5 kWh) for tactical/expeditionary power, Amphora 400 (400 VDC, 35 kW, 15 kWh) for high-demand systems (air defense, directed energy, medical, additive manufacturing), Vanguard (future high-voltage hybrid platform architecture for 10x more power/reach), Software-defined power layer for real-time power sensing, prioritization, and routing
Unique value
Only company applying commercial high-voltage EV/eVTOL power architectures to military tactical edge — delivering silent, low-signature, software-native power systems that reduce fuel consumption by up to 45%, enable undetected operations, and integrate with any energy source (generators, solar, vehicles, wall sockets)
Target customer
U.S. Department of Defense (Army, Marine Corps, Special Operations), allied militaries, Defense Innovation Unit (DIU), and commercial customers needing resilient edge power
Industries served
Defense & National Security, Military Energy & Power, Tactical Expeditionary Operations
Technology advantage
High-voltage hybrid-electric architecture adapted from commercial EV/eVTOL (Tesla, Archer); software-defined power management layer for real-time energy routing; modular, transportable form factors (Pelican-case sized); silent operation with low thermal signature; multi-source energy capture (generators, solar, vehicles, grid); field-tested with U.S. Army units within 6 months of founding
How they differentiate
Unlike traditional diesel generators or adapted commercial battery systems, Chariot builds purpose-built high-voltage hybrid power systems designed from the ground up for tactical military use — combining EV-grade battery architecture with a software-defined power OS that actively manages energy as a tactical resource, not just a commodity. Competitors offer incremental improvements (quieter generators, bigger batteries) while Chariot reimagines the entire power architecture for the modern battlefield.
Main competitors
DANNAR (Mobile Power Station), GM Defense, Epirus (power management for defense), Traditional defense prime power systems (AMMPS generators, legacy tactical microgrids)
Key partnerships
U.S. Army (Transforming in Contact initiative), Defense Innovation Unit (DIU Project GI, Artemis drone project), Naval Postgraduate School, 101st Airborne Division, Marine Corps teams
Notable customers
U.S. Army (Transforming in Contact initiative, Black Jack Brigade), Defense Innovation Unit (DIU Project GI, Artemis drone project), 101st Airborne Division, Marine Corps teams, Naval Postgraduate School, Commercial customers (unnamed)
Major milestones
2024: Company founded by Adam Warmoth, 2025-02: First field test with Naval Postgraduate School, 2025-05: Amphora systems fielded with troops, 2025-07: Emerged from stealth with $8M seed round led by General Catalyst and XYZ Venture Capital, 2025-07: Systems air-assaulted into force-on-force exercises, 2026-02: Raised $34M Series A led by Andreessen Horowitz ($41M total), 2026-02: Revenue generation achieved within 12 months of seed, 2026-02: Contracts with U.S. Army, DIU Project GI, and commercial customers
Growth metrics
Generated revenue within 12 months of seed funding; went from concept to fielded systems in under 6 months; systems deployed with U.S. Army at National Training Center rotation 26-02; contracts with U.S. Army, DIU Project GI, and commercial customers
Market positioning
Positioning to become the "power prime contractor" for modern warfare — analogous to how Anduril became a defense prime for autonomous systems, Chariot aims to be the foundational energy infrastructure layer that all next-gen military systems depend on
Geographic focus
United States (primary), with potential for allied nation military customers
