CX2 develops AI-enabled hardware and software to manage the electromagnetic spectrum for military use. Its platform autonomously detects, classifies, and counters RF threats at the tactical edge, providing spectrum awareness and emitter tracking with GPS-denied capability and optional high-resolution imagery for threat confirmation. The system is modular and hardware-agnostic, designed to be deployed on drones or vehicles and updated quickly at lower cost compared with traditional EW systems. The goal is to enable rapid, targeted responses to RF threats to protect missions for the U.S. military and its allies, leveraging a leadership team with deep military, defense, and tech experience.

Defense tech startup CX2, co-founded by Nathan Mintz and Porter Smith, announced a $31M Series A funding round in May 2023. The round was led by Point72 Ventures, with participation from new investors like Upfront Ventures, Pax Ventures, and 201 Ventures, as well as existing investors Andreessen Horowitz and 8VC. CX2 focuses on electronic warfare systems, aligning with the evolving nature of warfare, as seen in the Ukraine conflict.
Electronic warfare startup CX2 has raised $31 million in a Series A round led by Point72 Ventures, with participation from Andreessen Horowitz, 8VC, and Pax Ventures. The funding will help CX2 hire more staff and accelerate the development of its electronic warfare tools. CEO Nathan Mintz highlighted the importance of mastering the electromagnetic spectrum, especially in light of the Ukraine conflict. CX2 works with the U.S. Army's 10th Mountain Division and builds software and hardware for electronic warfare.
CX2, which is still in stealth, is being led by serial entrepreneur Nathan Mintz, who co-founded the counter-drone unicorn Epirus.
