In 2021, while perfecting their technology for detecting military communications and jamming,

Alex Wolfe, Ben Harp, and Isaac Stroll, Beta-tested their

work on a civilian population, their Harvard classmates.

The engineering students built a few dozen prototypes of small, low-cost radio sensors,

and asked their friends to put them in their rooms, then walked around campus talking on

handheld radios to refine

their detection algorithms. Wolf recalled, quote, we had some very funny looks from some of our

classmates. The company they founded while seniors at Harvard, distributed Spectrum, is now getting
