- Founded: 2018 by Jeff Cole and Gary Dominicos; based in Syracuse, New York. The team includes sensor engineers from the DoD, aviation authorities and NASA.
- Mission: Deliver scalable sensor infrastructure and airspace monitoring for civil and defense sectors, enhancing safety and critical infrastructure security by detecting drones, aircraft and other airborne threats in real time.
- Products & platform: The Airspace Monitoring Service (AMS) deploys networks of passive radar sensors to monitor low-altitude airspace and provides actionable data. Hidden Level’s passive radar and RF direction-finding technology detects drones, balloons, aircraft and operators without emitting signals. Sensors are offered as hardware and data-as-a-service.
- Technology: Utilizes passive radar and radio-frequency sensing to locate and track aerial objects and their operators while remaining undetectable. Vertical integration of design, manufacturing and testing optimizes cost, mobility and performance, ensuring privacy compliance.
- Customers & track record: Supplies technology to the U.S. Army, U.S. Air Force, Africa Command, Indo‑Pacific Command, Central Command, Northern Command, NASA and other federal, state and local agencies; systems have secured major events like the U.S. presidential inauguration.
- Funding: Raised $17.6M Series A in January 2021 led by Lobby Capital with backing from Lockheed Martin and others; closed a $35M Series B in 2024; secured a $65M Series C in February 2025 led by DFJ Growth, bringing total funding to around $100M.
- Business model: Provides passive radar sensors and airspace monitoring as hardware and subscription services to defense, critical infrastructure and public safety clients, enabling cost-effective, scalable deployments while ensuring privacy and regulatory compliance.
