Invisible. Adaptive. Precise.

Null Defense LLC is a Michigan-based defense technology company developing novel counter-unmanned aerial systems technology. Founded by Paul Keller, an independent inventor and technologist, Null Defense is built on the belief that the most effective countermeasures are invisible, adaptive, and precise.

The AAOD platform represents a fundamentally new approach to drone defense — one that operates at the intersection of computer vision, adversarial machine learning, and directed optical systems. Two provisional patent applications are on file with the USPTO covering the core system architecture and expanded capability doctrine.

Null Defense is actively seeking engagement with DoD program offices, SBIR opportunities, and prime contractor partnerships.
