SE3 raises $30M Series A to give military drones spatial smarts
What's the deal? SE3, a Munich-based startup building AI software that helps military drones and unmanned systems understand the world in 3D, has raised $30 million in a Series A round led by Accel. Keen, Lakestar, and Seedcamp also took part.
Why now? The round lands less than five months after SE3 emerged from stealth with €5.5 million ($6.1 million) in seed funding. It ranks among the largest Series A deals for a German 3D-technology company, sitting in the 96th percentile of 267 comparable rounds.
What's the endgame? SE3's software fuses video and sensor feeds from multiple drones and vehicles into a single 3D battlefield map — "like a mini map, how you would know it from a strategy game," cofounder and chief executive officer Lukas Köstler told Fortune . Soldiers can then query it in plain language or issue voice commands, such as requesting reconnaissance two kilometres north over a forest.
The company also builds AI that sits inside drones, letting them navigate when GPS is jammed, detect objects, and operate as a swarm. Köstler, previously of TeslaDealroom has a profile for this one. Try Dealroom →'s Autopilot team and Nvidia Research, said GPS-denied localisation is "very robust," while the fleet-command AI still needs one or two years of work.
Where it's headed: SE3 plans to hire and open European offices to scale across allied markets. The company holds contracts with Germany's armed forces, the Bundeswehr, and has technology deployed in Ukraine. As a German firm bound by strict export laws, it serves European NATO members and their allies.
What could go wrong? SE3 is betting militaries will want software untied to any single hardware maker, warning that proprietary stacks risk costly lock-in within two or three years. That pitch puts it alongside better-funded drone makers that control their own software. Military AI also draws scrutiny: the Pentagon designated Anthropic a supply-chain risk in March after it refused fully autonomous weapons use.
The signal: European defence-tech funding is surging, with Dealroom and Resilience Media reporting $7.4 billion raised by September 2026 and a record $10.5 billion on track for the year. Drone and autonomous-systems firms drew $4.7 billion across 40 rounds, led by giants like Helsing and Quantum Systems. SE3 is far smaller, but its hardware-agnostic software layer targets a distinct gap: shared awareness and navigation when the giants' platforms go dark.
