Chariot Defense

Transportable hybrid power systems for defense

Overview

Chariot Defense makes portable, software-defined hybrid power systems called Amphora that store, convert, and route energy to power drones, sensors, radios, electronic warfare equipment, and directed-energy devices. Amphora units pull energy from generators, vehicles, and solar sources and use software to optimize and direct power where it is needed on the battlefield. The products are designed to have low electronic, thermal, and acoustic signatures and act as field-ready power hubs that enable integrated power management across platforms. The company aims to scale Amphora production, develop a battlefield power operating system, and grow its engineering team, supported by seed and Series A funding from investors including General Catalyst, XYZ, Andreessen Horowitz, DCVC, and others for defense customers such as the Army and DIU.

Simplify's Take

What believers are saying

  • The August 2026 $7.6 million DIU PRISM award validates Amphora with near-term revenue.
  • February 2026 brought $34 million Series A, funding production and battlefield-power operating-system development.
  • Open engineering roles in San Bruno show aggressive hiring for embedded, mechanical, and systems scale.

What critics are saying

  • PRISM deliverables start fall 2026; missed Army brigade deployment kills follow-on procurement.
  • Hardware manufacturing, MIL-STD qualification, and supply-chain scaling can trap Chariot in prototype purgatory.
  • A single-program defense startup lives or dies on DIU and Army budgets; contract loss is existential.

What makes Chariot Defense unique

  • Amphora software-defined power orchestrates generators, solar, vehicles, storage for tactical loads in real time.
  • Chariot fielded Amphora in NTC Transforming in Contact and Army brigade exercises before Series A.
  • Adam Warmoth brings Anduril and Archer execution culture, accelerating field deployment and product iteration.

Chariot Defense wins $7.6M DIU contract to deploy tactical power grids for US Army brigades

Chariot Defense has secured a $7.6 million contract from the Department of Defense Innovation Unit under the Portable Resilient Integrated Storage Module programme. The San Bruno-based defence technology startup will deploy its Amphora power systems to US Army brigades this autumn. The systems address battlefield power shortages by integrating with existing generators, solar arrays, and military vehicles. Amphora has demonstrated the ability to reduce fuel consumption by up to 60% and extend silent operations up to 36 hours. Founded in August 2024 by Adam Warmoth, formerly of Anduril Industries, Chariot Defense has raised $41 million in venture funding. This includes a $34 million Series A round led by Andreessen Horowitz.

Chariot Defense raises $34M Series A led by Andreessen Horowitz for battlefield power systems

Chariot Defense has raised $34 million in Series A funding led by Andreessen Horowitz, bringing total funding to $41 million. DCVC, LMNT, Marlinspike, Overmatch, Shield Capital, Ensemble and Trenches Capital participated, alongside existing investors General Catalyst and XYZ. Founded in 2024, the defence technology firm develops deployable power systems that enable real-time monitoring and control of energy distribution across military operations. Its Amphora hybrid systems integrate energy storage, conversion and distribution to maximise force effectiveness whilst minimising operational signatures. The funding will accelerate production of Chariot's systems and support development of an integrated operating system for battlefield power management. The company has already generated revenue within its first year and deployed equipment in military exercises. Chariot is expanding its engineering team to meet growing demand from military units.

Chariot Defense Announces $34M Series A led by Andreessen Horowitz to scale command of power on the battlefield.

Chariot Defense announces $34M Series A led by Andreessen Horowitz to scale command of power on the battlefield. Feb 25, 2026, 06:31 ET SAN FRANCISCO, Feb. 25, 2026 /PRNewswire/ - Chariot Defense, a defense technology company pioneering next-generation battlefield power systems, today announced it has raised $34 million in Series A funding, bringing total funding to $41 million. The round was led by new investor Andreessen Horowitz, and with new participation from DCVC, LMNT, Marlinspike, Overmatch, Shield Capital, Ensemble, and Trenches Capital. Existing investors General Catalyst and XYZ also participated. Power is becoming the critical constraint across military operations. To solve this pressing challenge, Chariot Defense has built a deployable, software-defined power layer that senses, prioritizes, and routes power across mission-critical systems in real time, enabling warfighters to operate without interruption, detectable signature, or wasted capacity. "We're on a mission to ensure power is never the limiting factor in modern warfare," said Adam Warmoth, Chariot Defense Founder and CEO. "Power on the battlefield is less about how much energy you carry; it is more about how intelligently you control and distribute it. Chariot's Amphora systems act as a combat multiplier in the field, enabling soldiers to operate with greater freedom. We enhance their ability to see, sense, strike, and survive in contested environments. The speed with which warfighters have adopted our systems is a testament to our technology and our incredible team. We're already turning this capital into capabilities as we scale to meet the growing demand." The funding comes on the heels of new sales and contracts with the U.S. Army, DIU Project GI, and commercial customers. "Incredible breakthroughs in power are happening in the commercial world, from advanced batteries, to next-generation microcontrollers and power electronics, while much of defense still relies on legacy systems," said Erin Price-Wright, General Partner at Andreessen Horowitz. "Chariot is bringing that innovation directly into national security and building the software-defined power backbone our modern military systems demand. The future of defense will be shaped by energy, speed, and adaptability, and Chariot is leading that shift." Investing to Meet Urgent Demand The raise will accelerate production of Chariot's agile power system products and support the development of an operating system for the command, control, and distribution of electric power on the battlefield. The funding will also enable Chariot to significantly expand its engineering team to meet surging demand. This news comes just six months after the company launched out of stealth in July 2025. "We are excited to back Chariot again, as they have operationalized the Anduril-style playbook of defense problem solving and productization by driving systems to the field early and iterating essential features quickly to get them deployed." says Ross Fubini, Managing Partner at XYZ Venture Capital. "Demand for rapid fielding has never been stronger, and Chariot is a prime example of transformation in contact." Leading with the Amphora Product Modern operations are failing from lack of power. Chariot's universal and agile Amphora hybrid power systems enhance warfighter lethality and survivability by tightly integrating energy storage, conversion, and distribution capabilities to deliver power when, where, and how it is needed. These systems are already being adopted by units to extend operational independence and better adapt during distributed, expeditionary missions via ubiquitous, dependable power. Chariot has directly sold Amphora systems to customers following recent exercises, including to commercial customers who recognize the importance of power to accelerate their own innovation and to create resilience in their existing deployments. Building for Scale Warmoth concluded: "Chariot went from seed round to air-assaulting equipment into force-on-force exercises within six months and we generated revenue within twelve months. That kind of traction is exactly why we're rapidly expanding." The company is actively recruiting mechanical, electrical, and software engineers with expertise in high-voltage energy storage, power electronics, and distributed systems to build the power infrastructure that will define modern military operations. About Chariot Defense: Chariot Defense is a defense technology company pioneering next-generation power distribution systems built for the demands of modern warfare. Its Amphora platform provides modular voltage and low-signature power at the tactical edge - powering everything from radios and drones to sensors and directed energy systems.
