ZeroMark, Inc.
ZeroMark is a New York-based defense technology company building an AI targeting layer that turns ordinary infantry weapons into precision counter-drone systems. Its flagship Apex is a rifle-mounted, software-defined fire control system that uses electro-optical cameras, LiDAR and machine-vision ballistics to physically adjust a soldier's aim in real time, letting a dismounted operator hit small, fast-moving drones without specialist training. Founded in 2022 by former U.S. Navy servicemember and ex-MongoDB executive Joel Anderson, ZeroMark has raised roughly $7M in seed funding led by Ground Up Ventures and Andreessen Horowitz, followed by a 2025 strategic round, and has demonstrated its system in a U.S. Marine Corps live-fire exercise.
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.
