Revolution Growth Invests in Hidden Level, the Company Building the World’s Most Advanced Drone Detection Technology

The $65M Series C will be used to expand production of its airspace monitoring technology, grow its Syracuse-based team, and scale internationally.

Meet Hidden Level — the leading developer of technology for sensing, identifying, tracking, and analyzing radio frequency (RF) spectrum signals to help customers detect potential threats. Hidden Level’s mission: to keep people safe, infrastructure secure, and communities peaceful by modernizing how we monitor low-altitude airspace.

What They’re Solving For: The rapid proliferation of drones, advanced air mobility (AAM) technologies, and sophisticated cyber threats have made low-altitude airspace a critical frontier. Growing challenges include:

Hidden Level’s integrated technology addresses each of these issues, combining radar, antenna, and the ability to sense, protect, and communicate into a single platform.

What They Do: Hidden Level offers scalable low-altitude airspace monitoring that provides real-time, actionable data to meet defense, critical infrastructure, and public safety needs. The company’s passive radar and electronic warfare sensing technology detects and tracks aircraft, dark drones, and ambient RF signals, differentiating regular activity from threats. The company’s sensors are also engineered to remain undetectable, ensuring that bad actors can neither disrupt nor disable monitoring operations.

How They Do It: Customers can own and maintain their own hardware or tap into Hidden Level’s global sensor network, which uses existing infrastructure like rooftops and cell towers to blanket urban airspace. The network’s interoperable architecture offers encrypted, real-time data that provides unparalleled situational awareness at a fraction of the cost of other providers.

The Results To-Date: Hidden Level’s technology has been validated by the Department of Defense, securing a Low-Rate Initial Production (LRIP) contract under the Army’s FoCUS Program of Record. The Hidden Level team has also worked with major government agencies, including the Department of Homeland Security, Federal Aviation Administration, NASA, and Air Force, positioning itself as the go-to provider for airspace security in the most demanding settings.

Why We Like It: Hidden Level’s leadership has deep advanced sensing technology expertise, honed at previous posts at the DoD, aviation authorities, and NASA. The team is both practical and ambitious, building meticulously reliable and durable solutions for today while relentlessly pursuing what’s next in airspace monitoring. In their words, functional tech > fictional tech. With strong market tailwinds (the counter-unmanned aircraft systems market is projected to grow at an average yearly rate of nearly 30% from 2025 to 2030), top-tier defense tech backing (from the likes of Lockheed Martin and Booz Allen), and a purpose-driven team of tech optimists (committed to transparency, privacy, and safeguarding people and places), Hidden Level is well-positioned for growth.

Co-founders Jeff Cole and Gary Dominicos

Where They’re Headed: Hidden Level will use its Series C funding to expand its team, manufacturing capabilities, and international footprint to serve emerging commercial, public, and defense needs.

We’re thrilled to welcome Hidden Level to our portfolio of companies operating at the intersection of tech and policy. We look forward to partnering with CEO Jeff Cole and his team in their mission to safeguard our skies.
