Swarmer develops software that makes drones autonomous and allows them to operate together, in large, coordinated teams — no pilots needed. Our technology has been battle-tested in Ukraine— the world’s most intense proving ground for drone warfare.
In March 2026, we became the first Ukrainian defense startup to go public on NASDAQ, following a $15M Series A — the largest investment in a Ukrainian defense tech company since the start of the war.
Working at Swarmer means operating at the intersection of engineering rigor and frontline reality. The problems and environments are complex, and the stakes are very real. We built this software to enable democratic nations to defend themselves.
If you are motivated by building resilient systems that matter and by seeing the direct impact of your work, you’ll find purpose here.

What We Do
Swarmer develops software systems that allow unmanned vehicles to act autonomously and work together in large teams. Its systems are centered on ethical AI and require humans to make all life-or-death decisions, while also allowing computers to do what they do best—processing large quantities of information and reacting to the rapidly changing environment in split seconds. Swarmer has successfully demonstrated swarms of up to 25 drones working together in GNSS-denied environments. In the near future, it plans to demonstrate combined-arms operations involving 100+ drones of various kinds, working in concert to seamlessly integrate UAS, USV, UGV, and stationary launchers into a single swarm that functions as one unit. Beyond defense applications, Swarmer’s hardware-agnostic platform positions the company to transform civilian markets from precision agriculture and emergency response to infrastructure inspections and environmental monitoring.
