The enemy gets a vote, too. That military aphorism took on a chilling immediacy for Brandon Tseng when he was training for an Afghanistan deployment as a Navy SEAL in 2012. His team was simulating clearing a house of enemy fighters when the Naval Academy graduate was suddenly shot in the face. Fortunately it was just a paintball, not a real bullet. “I’d followed my training exactly as taught,” he remembers—but it didn’t matter. One point of the exercise was that preparation isn’t always enough, because adversaries are smart and unpredictable. “If that was real-life combat, I would’ve been killed.”Clearing hostile buildings was part of the daily grind for the United States military post-9/11. It is extraordinarily dangerous work and killed or injured several people Tseng knew. When he left the military in 2015 after seven years, he couldn’t stop thinking of ways that AI and autonomy tech could reduce risks to troops, like by letting them scan inside structures before they barged in. Tseng convinced his older brother, Ryan, already a successful entrepreneur who had sold his wireless charging company to Qualcomm, and Andrew Reiter, an engineer with a master’s in robotics from Harvard, to join him in starting a drone company they called Shield AI. (Tseng got his Harvard MBA concurrently.) Its first product was a small “Nova” quadcopter specialized for scouting and mapping buildings while sending live video back to frontline soldiers.Today Shield AI is one of the most valuable defense tech unicorns in the nation, worth $12.7 billion after its most recent fundraising in March. Israelis used the more than $400 million (revenue) company’s Novas to survey Hamas tunnels in Gaza and rescue hostages after the attacks of October 7, 2023; Ukrainians are using Shield AI’s bigger V-BAT drone to identify targets deep inside Russian-held territory. Forbes estimates that the Tsengs, who are co-presidents, each have a stake worth around $400 million.By Monica Hunter-Hart,ReporterLearn more about your ad choices.
