See the Invisible.
Detect Weapons.
Save Lives.

We make concealed weapons detection accessible to every organization and location that needs it.

Why we started
Cambridge Terahertz

Our founder, Nathan Monroe, grew up in Florida. His high school experienced a shooting. That personal connection to the human cost of gun violence drove him to spend over a decade at MIT developing technology that could help prevent such tragedies.

The result is Cambridge Terahertz: the world’s first compact, affordable concealed weapons detection system that delivers airport-grade security in a device that fits in your hand.

We believe even one death from a concealed weapon is too many. And we believe every school, hospital, workplace, and public space deserves access to technology that can help prevent violence—without treating people like suspects.

Our approach

Security should be invisible.

The best security makes people feel safe, not surveilled. Our technology works in the background so people can go about their day naturally.

Cambridge UI demonstrating privacy-focused scanning

Privacy is non-negotiable.

We designed our system so that raw images are only ever seen by AI. Humans receive only the information they need to act—nothing more.

Trust is earned.

The security industry has been burned by vendors who over-promise. We’re transparent about what our technology can and can’t do—and we back our claims with real-world validation.

Built on a Decade of MIT Research

Cambridge Terahertz spun out of MIT in 2021, commercializing breakthrough research in terahertz sensor. Our proprietary on-chip radar technology does what was previously impossible: deliver the sensor capability of large airport scanners in a compact, affordable, deployable package.

The core technology uses safe, non-ionizing radio waves to see through clothing and materials, creating detailed 3D images that AI interprets in real time. It’s the same fundamental approach used in airports—but miniaturized, modernized, and made practical for enterprise applications.
