Company Overview
Haygui LLC is a defense engineering firm specializing in counter-unmanned aerial systems (C-UAS) technology. We design, develop, and integrate detection and defeat capabilities for the U.S. military and national security community — applying rigorous systems engineering to one of the most rapidly evolving threat domains in modern warfare.
We operate as a lean, engineering-first organization. Our team brings hands-on experience across the full C-UAS lifecycle — from initial concept and threat analysis through hardware development, software integration, field testing, and operational transition. We maintain close working relationships with government customers and understand the requirements, acquisition pathways, and constraints of the defense environment.
