Allen Control Systems

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.
