From high-school science fairs and campus walkie-talkie tests to a New York defense startup, Alex Wulff has spent a decade making invisible signals legible - and low-cost radio hardware useful in the field.

Kris Merkel is the President and CEO of S2 Corporation, a Bozeman, Montana deep-tech firm turning rare-earth-doped crystals into an optical computer that watches the entire radio spectrum at once. A physicist by training and a patient operator by temperament, he has spent more than two decades pulling a niche piece of laboratory physics, spatial-spectral holography, out of Montana State University and into the hands of the U.S. Department of Defense, DARPA, and the intelligence community.
Nathan Mintz is the co-founder and CEO of CX2, an El Segundo defense-tech startup building AI-enabled hardware and software to detect, disrupt, and destroy threats in the electromagnetic spectrum. A Stanford-trained electrical engineer who spent 14 years designing radar and electronic-warfare systems at Raytheon and Boeing, he went on to co-found directed-energy unicorn Epirus and automotive-radar company Spartan Radar before launching CX2 in 2024. He argues modern warfare has reached 'consumer scale,' where multimillion-dollar missiles are wasted on cheap drones, and that control of the spectrum now matters as much as supply lines did in the 20th century. CX2 raised a $31M Series A led by Point72 Ventures in May 2025, part of $46M total funding.
