The airport security line is a study in trade-offs. You can have speed, or you can have certainty. X-rays see density, not materials. Manual searches are slow and invasive. The ideal system would scan an object at a conveyor belt's pace and whisper back exactly what's inside, all without a hint of radiation.
Spectrohm, a Virginia-based hardware startup, is betting its answer lies in a specific slice of the radio spectrum. The company has built inspection systems that use radio-frequency (RF) imaging to map the internal structure of bags, parcels, and people, identifying materials by their distinct electrical properties rather than just their density. The core pitch is a triple play: it’s non-ionizing, requires no physical contact, and works at the speed of a moving conveyor belt.
The RF imaging wedge
Traditional security scanners are essentially density mappers. Spectrohm’s technology images the electrical properties of materials. Different substances interact with radio waves in unique ways. The company says this lets its systems ‘see in color,’ distinguishing, for example, a block of cheese from a block of plastic explosive with similar density. This material identification happens simultaneously with the imaging, in a single pass.
The company has packaged this technology into two main product lines: CheckStream for bags and backpacks, and CargoStream for packages. The January 2025 acquisition of high-speed bag screening technology from UK-based Iconal Technology Ltd was a clear move to bolster its aviation security offering, specifically for the high-throughput screening of carry-on luggage.
The People Building It
Founder and CEO Tim Cargol spent twelve years as a Senior Intelligence Officer for the U.S. government, focusing on proliferation challenges and nuclear policy. He likely spent a career looking at the output of various sensing technologies and understanding their gaps from an operational perspective. The rest of the known team is lean, with a Director of Engineering and a Software Architect listed.

Funding and the path to traction
Spectrohm raised a $2 million seed round in May 2022, led by HCVC. The investor list is a mix of specialist hardware funds like Hardware Club and HCVC, regional players like Virginia Venture Partners, and angel networks.
Public traction is the classic early-stage hardware black box. The company is actively seeking pilot programs for both CheckStream and CargoStream, but has not disclosed any named customer deployments. A third-party estimate places its revenue in the $1 million to $5 million range, though this is uncorroborated.
Where the signal could get noisy
The security screening market is not empty. Spectrohm will have to convince buyers to move away from entrenched, certified incumbents. Its most direct competitors appear to be other companies applying novel sensing to physical security, like Liberty Defense with its HEXWAVE millimeter-wave walkthrough portal.
- Certification marathon. Any system used in aviation or critical infrastructure must undergo lengthy, expensive certification processes. This is a regulatory moat for incumbents.
- The performance threshold. Does RF imaging provide enough of a material-identification advantage over advanced X-ray/CT to justify a switch?
- Sales cycle stamina. Selling six- or seven-figure hardware systems into government and large enterprises requires patience and capital.
The next checkpoint
The next twelve months should be about converting pilot interest into a reference customer. A publicly announced deployment, even a single-lane pilot at a mid-sized airport or a major parcel distribution center, would be the strongest possible signal. It would validate the technology in a real-world environment and provide the case study needed to fuel a likely Series A round.
For Spectrohm to succeed, it doesn’t need to replace every X-ray machine on day one. It needs to become the preferred choice for the specific, high-value use cases where its material intelligence and safety features matter most.
