Hidden Level builds passive radar and RF direction‑finding technology to detect and precisely locate drones (including dark drones), aircraft, balloons and their operators, delivering real‑time, actionable airspace awareness. The company offers vertically integrated, scalable solutions delivered as hardware or data‑as‑a‑service and emphasizes privacy compliance under Title 18. Its sensors are designed for cost, mobility, performance and broad spectrum coverage and are used in high‑security scenarios such as presidential inaugurations. Hidden Level has active contracts and deployments with federal customers including NASA, the U.S. Army, the U.S. Air Force and multiple Combatant Commands. The company plans to use new capital to expand manufacturing, hire across the organization, and grow internationally following successful deployments with over a dozen customers. Hidden Level was founded in 2018 and is based in Syracuse, N.Y. Hidden Level is a sensor-technology company focused on Tactical Passive Radar for Counter Unmanned Air Systems (UAS). The company was selected by the U.S. Department of Defense for APFIT pilot-program funding to transition its technology from development into production. The APFIT award is intended to accelerate fielding of Hidden Level’s capability to the U.S. Army. Hidden Level describes itself as a pre-Series B business and received USD10 million in DoD funding as part of the award. The company was one of only 11 firms awarded APFIT funding by the DoD in 2023. The award is positioned to help deliver capability a year or two earlier than scheduled while supporting the U.S. industrial base through investment in small businesses and nontraditional defense-developed capabilities. Hidden Level builds passive sensing systems that use next-generation radio frequency (RF) sensing technology to provide multi-domain situational awareness and support counter-UAS missions. Its sensors detect and track low-altitude airborne threats using adaptive RF signal detection techniques to increase airspace awareness and inform countermeasure opportunities. The company positions its technology for both tactical and strategic support to Department of Defense missions and for dual-use applications. Leadership says the firm will work with Booz Allen to support DOD missions and provide critical insights for soldiers on the ground. The company’s technology emphasis is on improving decision advantage for warfighters in high-interference environments. No financial metrics for Hidden Level are disclosed in the article.
