Chariot Defense, a defense technology company founded in 2024, has closed a $34 million Series A round, bringing its total funding to $41 million. The round was led by Andreessen Horowitz, with new participation from DCVC, LMNT, Marlinspike, Overmatch, Shield Capital, Ensemble, and Trenches Capital. Existing investors General Catalyst and XYZ Venture Capital also joined the round.
The company, which builds software-defined power systems for military use, has moved quickly since launch. Just six months after coming out of stealth in July 2025, Chariot is already operating under contracts with the U.S. Army, the Defense Innovation Unit's Project GI, and several commercial customers.
Power is one of the most overlooked constraints in modern military operations. Soldiers in the field carry radios, drones, sensors, and other high-draw electronics. When power fails, so does the mission.
Chariot's answer is the Amphora platform, a modular, software-defined system that monitors, prioritizes, and routes power across multiple devices in real time. Rather than simply increasing energy capacity, Amphora controls how power is distributed, reducing both waste and the electronic signatures that can expose a unit's position.
"Power on the battlefield is less about how much energy you carry; it is more about how intelligently you control and distribute it," said Adam Warmoth, Chariot's Founder and CEO. "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 new capital will go directly into production and engineering. Chariot plans to expand its Amphora product line, accelerate the development of a full operating system for battlefield power command and distribution, and hire mechanical, electrical, and software engineers with backgrounds in high-voltage energy storage, power electronics, and distributed systems.
Warmoth pointed to the company's pace so far as evidence of what more resources will enable: "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 defense sector has been slow to adopt newer power technologies that are now widely used in commercial applications, from advanced battery chemistries to next-generation power electronics. Chariot's thesis is that this gap creates risk for the military and an opportunity for companies that can bridge the two worlds.
Erin Price-Wright, General Partner at Andreessen Horowitz, put it plainly: "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. Chariot is bringing that innovation directly into national security and building the software-defined power backbone our modern military systems demand."
The Amphora systems are already being used in distributed and expeditionary missions, where consistent, low-signature power access can mean the difference between operational independence and dependency on resupply. Chariot has also made direct commercial sales following recent field exercises, an indication that the technology is proving itself outside purely military contexts as well.
Chariot Defense was founded in 2024 and is headquartered with a team that brings experience across defense, technology, and government. The company's Amphora platform delivers modular voltage management and low-signature power at the tactical edge, powering systems ranging from communications equipment and drones to sensors and directed energy weapons.
The company's early trajectory has drawn attention in the defense investment community. Ross Fubini, Managing Partner at XYZ Venture Capital, described Chariot's approach as applying a proven technology company playbook to defense problems: "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. Demand for rapid fielding has never been stronger, and Chariot is a prime example of transformation in contact."
Chariot is currently recruiting across engineering disciplines and continues to expand its work with both military and commercial partners as it scales to meet growing demand.
