Allen Control Systems (ACS) is an Austin-based defense technology company building Bullfrog, an AI-powered autonomous robotic weapon station designed to detect, track and shoot down hostile drones. Founded in 2022 by three engineer-entrepreneurs, ACS uses passive machine vision and custom fire-control software to turn standard machine guns into precision counter-drone turrets, aiming to cut the cost-per-kill of a drone from expensive missiles down to a few dollars of ammunition. The company raised a $200M Series B in 2026 at a $2.2B valuation to scale manufacturing for the U.S. military and allied forces.
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.
