SE3 raises $30 million Series A led by Accel for spatial AI software that runs on drones and ground robots from different makers
SE3, a Munich startup that builds spatial AI software for military drones and other unmanned systems, has raised a $30 million Series A, €26.4 million, led by Accel, with Keen, Lakestar and Seedcamp also investing, Fortune and the F.A.Z. reported on Thursday, Nov. 12, 2026. The round comes less than five months after SE3, which has since dropped "Labs" from its name, came out of stealth in June with €5.5 million ($6.1 million) in seed funding.
The software fuses video and sensor feeds from several drones and ground vehicles into one 3D picture of the battlefield that soldiers can query and command in plain language. Fortune puts the team at roughly 40 employees; the F.A.Z. says about 45, with a plan to reach about 120 within six months. SE3 did not disclose revenue, contract values or a valuation.
Servospace take: a bet that the autonomy layer can be sold apart from the airframe
Servospace analysis: SE3 is pitching itself as a neutral software layer across drones and ground vehicles from different manufacturers, not another drone maker. Köstler told Fortune that if each drone maker controls its own software stack, customers struggle to make systems from different vendors work together and face costly lock-in within two or three years. SE3's press release ties demand to the Modular Open Systems Approach and Germany's MOSABw program, which it says make it easier for armed forces to mix suppliers.
Who makes money: Servospace analysis of the pitch, not a disclosed commercial split. SE3 is selling software that it says runs across other companies' drones and vehicles; none of the Series A sources say who keeps the hardware invoice or what SE3 charges. Auterion founder Lorenz Meier said in SE3's release that SE3's software runs on Auterion's Skynode, so customers get it "on the platforms they already operate, across manufacturers." Fortune lists sensor maker Hensoldt, drone software company Auterion, and drone developer ERC as partners. The risk, Resilience Media noted at the seed round, is that many drone and ground-vehicle makers build their own spatial tools in-house. Resilience also described SE3's seed-era product as including a proprietary hardware module on the vehicle, which the Series A materials do not revisit.
The traction claims are the company's. SE3 says it has shipped thousands of systems in two years and has contracts with Ukraine and the Bundeswehr. Köstler told Fortune that GPS-free self-location, the most basic capability, has been delivered thousands of times and is "very robust," but that the fleet-command AI is less mature, with "still much that needs to be built out over the next one or two years."
By Servospace math, the $30 million is about 4.9 times the $6.1 million seed, for about $36 million disclosed in total. Lakestar and Seedcamp also backed the June seed, Resilience Media reported. Defense will drive revenue for at least the next 12 months, Köstler told Fortune, with civilian uses such as robotics and emergency response to be explored from 2027, according to the company.
