Sentry

Air defense one soldier can carry

Drones now hunt soldiers on foot. Bases and vehicles already have options. The soldier walking a tree line is the most exposed, and often far from any big air defense. Erik founded Sentry to change that.

Sentry is a counter-drone system worn as a pack. It’s designed to find an incoming drone more than one way, even one flying on a fiber-optic cable with no radio link to jam. Then it’s designed to launch a folded interceptor that flies out with its net open and catches the drone before it reaches the soldier. The interceptor’s onboard AI learns from how experienced combat pilots fly.

A squad’s packs are designed to work as one system, and the interceptor is modular, so it can change as the drones do.

Erik Finman is an engineer and founder who likes working on the frontier.

At 12, his grandmother gave him $1,000 for his college fund, and he put it into Bitcoin instead, at about $12 a coin. At 15 he left high school, used his Bitcoin gains to start Botangle, an education startup, and moved to Silicon Valley. He later sold Botangle, and at 18 he became the youngest Bitcoin millionaire.

He has spent that money building hard things. He started Project Da Vinci at 17, won a NASA contract on its ELaNa mission and watched the satellite launch to orbit on a Rocket Lab Electron. He built a real-life Doctor Octopus suit with four robotic arms. Now he’s all in on Sentry, a counter-drone system one soldier can carry.

  • Launched The Project Da Vinci Satellite

    Applied at 17 and, with a dedicated team, won a NASA contract on its ELaNa mission and launched the Project Da Vinci satellite to orbit at 20, on a Rocket Lab Electron in December 2018. Inspired by Carl Sagan’s Golden Record, the satellite served as a modern time capsule, carrying videos from nearly every country in the world. It also featured contributions from renowned artists, including a custom mixtape and personalized message from Taylor Swift, as well as messages from politicians, creators, entrepreneurs, and visionaries who represent the diverse fabric of humanity. It also carried a crypto wallet and sent one of the first crypto transactions from orbit, to a school in Ghana, testing payments over a satellite link where internet access is scarce.

  • Real Life Dr. Octopus Suit

    Engineered a working robotic exoskeleton inspired by Marvel’s Doctor Octopus: four 3D printed arms driven by eight motors, with microcontrollers on the back that map the two middle fingers of each hand to multiple axes of arm motion. It debuted at Comic-Con and points toward what assistive wearable robotics can do.
