Cambridge Terahertz is an MIT spinout building a chip-based imaging system that combines the 3D vision of lidar with the see-through power of X-ray, but using human-safe terahertz waves at a thousandth the power of a cell phone. Shrunk from an airport-scale scanner into a palm-sized, two-pound device, its AI-powered sensors detect concealed weapons through clothing and bags, and can see inside sealed packages without opening them. Founded in 2023 by MIT PhD Nathan Monroe, the company raised a $12M seed round led by Felicis with participation from Amazon's Industrial Innovation Fund.
Nathan Monroe is the co-founder and CEO of Cambridge Terahertz, an MIT spinout building compact, affordable concealed-weapons detection. A PhD electrical engineer who demonstrated one of the largest terahertz phased antenna arrays ever built on standard CMOS, he shrank refrigerator-sized scanner physics into a device smaller than a toaster. After a school shooting marked his teenage years in Florida, he spent more than a decade at MIT turning terahertz sensing into a real product. Cambridge Terahertz uses safe, non-ionizing radio waves and AI to see weapons through clothing and packaging, and raised a $12M seed round backed by Amazon and Felicis.
