After helping design a rotorcraft for Titan, the Penn State engineer traded interplanetary patience for two-week build-test cycles. His new problem is brutally terrestrial: making drone defense cheap enough to use at scale.

After building aircraft autonomy at Shield AI, the Georgia Tech computer scientist found his startup idea in defense technology's least glamorous corner: getting incompatible machines to cooperate.
Joel Anderson is the founder and CEO of ZeroMark, a New York defense-technology startup building an AI-and-robotics fire control system that turns ordinary infantry rifles into auto-aiming counter-drone weapons. A U.S. Navy veteran who went on to help scale MongoDB from a small team to a public company as a senior technical and security leader, Anderson founded ZeroMark in 2022 after an 'epiphany' driving his Tesla to a shooting range: consumer machines could aim and track better than a soldier could. Backed by Andreessen Horowitz's American Dynamism fund and Ground Up Ventures, ZeroMark markets what it calls a 'handheld Iron Dome' - a motorized buttstock and sensor pod that make hitting a small drone at 200 yards, in Anderson's words, 'as easy as hitting a 60-foot-diameter circle.'
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.
