Company profile
researched Aug 2026Hidden Level develops hardware and software that detect and interpret radio-frequency (RF) activity and convert it into intelligence products spanning the air, ground, sea and space domains. Its offering is organized around an "RF Intelligent Platform" intended to serve as a shared RF layer on which additional applications can be built, together with an airspace intelligence line that includes passive RF sensing for detection and tracking of uncrewed aerial systems. Deliverables described by the company combine configurable sensor hardware, SaaS-delivered intelligence and integration-ready infrastructure designed to feed customers' existing systems rather than operate standalone.
Published use cases center on counter-uncrewed aerial system (CUAS) and airspace awareness missions. The company describes AI-driven airspace monitoring deployments, persistent passive airspace awareness for Special Operations Forces operating at low altitude and short range, and expeditionary RF sensing concepts for distributed operations in the Indo-Pacific. A cited deployment at Stewart Air National Guard Base is described as being established within 24 hours and supporting real-time drone tracking, a seven-minute interdiction and multi-agency coordination. A municipal example involves the Arlington, Texas police department using the company's Airspace Monitoring Service (AMS) to detect and deter unsafe or criminal drone activity around large public events in the city's entertainment district.
Business model
Hidden Level sells configurable RF sensing hardware alongside SaaS-based intelligence services and integration-ready infrastructure, and also offers access to its RF infrastructure and proprietary data for research and development users. One described service model, the Airspace Monitoring Service, provides persistent RF awareness to customers without requiring them to build their own sensing infrastructure.
Latest developments
Recent company publications address persistent passive airspace awareness for Special Operations Forces at the tactical edge, expeditionary RF sensing for distributed operations in the Indo-Pacific region, guidance on evaluating AI claims in CUAS systems, and an airspace security deployment at Stewart Air National Guard Base.
▸Full profile — market position, technology, go-to-market, geography
Market position
Hidden Level positions itself in the counter-uncrewed aerial system and airspace awareness market, emphasizing operationally fielded, AI-enabled passive RF detection over unproven capability claims.
Technology
The company's technology is based on passive RF sensing: sensors detect radio-frequency emissions to identify and track cooperative and non-cooperative airborne objects without emitting, feeding a platform layer that applies AI to airspace monitoring data. The platform is designed to integrate with customer systems as a single shared RF layer supporting multiple downstream applications.
Go-to-market
The company engages defense, government and critical infrastructure customers directly through dedicated sales, partnership, support and community channels, publishes case studies and technical explainers, appears at industry events, and maintains a newsletter covering deployments and product developments.
Government, defense and commercial organizations requiring RF and airspace awareness, including military units such as Special Operations Forces, critical infrastructure and homeland security operators, public safety and law enforcement agencies (for example municipal police departments), and research and development teams.
Geography
Deployments referenced include U.S. sites such as Stewart Air National Guard Base and the city of Arlington, Texas; company materials also discuss expeditionary sensing concepts for the Indo-Pacific theater.
