About Haygui

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.

Our Mission

The small UAS threat is no longer an emerging concern — it is a present and growing challenge for both military and homeland security operations. Commercial drones have been weaponized, adapted for ISR, and employed as swarming platforms in nearly every operational environment on the modern battlefield.

Haygui exists to close that gap. We build the detection, tracking, and defeat capabilities that operators need in the field: effective, fielding-ready systems that can be sustained, trained, and integrated with minimal burden on the unit. Our work is focused entirely on this domain — no distractions, no division of attention across unrelated business areas.

Serving the Defense Community

Haygui LLC is registered in SAM.gov and maintains all required registrations for government contract actions. We work directly with program offices, contracting agencies, and prime contractors across DoD and interagency customers.

Our size is an advantage. Decisions are made by senior engineers, not program managers. Customers get direct access to the people doing the work — no middlemen, no dilution of expertise.

We support programs across multiple acquisition pathways: direct FAR-based contract actions, Other Transaction Authority (OTA) agreements, subcontracting with prime contractors, and collaborative R&D partnerships with government laboratories and FFRDCs. If your program has a C-UAS requirement, we want to hear from you.
