SE3 Raises $30M to Power Military Drones with Spatial Intelligence and GPS-Free Navigation

SE3 Raises $30M Series A Funding Led by Accel

SE3, a Munich-based startup developing spatial intelligence software for autonomous systems, has closed a $30M Series A funding round led by Accel1

. Keen, Lakestar, and Seedcamp joined the round, which arrives just five months after the company emerged from stealth with €5.5M ($6.1 million) in seed funding1

. The Technical University of Munich spin-out focuses on building AI software for military drones and unmanned systems that struggle with three-dimensional understanding—a critical gap in current AI capabilities.

Building 3D Battlefield Maps from Sensor Data Fusion

SE3's platform-agnostic software processes video and sensor feeds from multiple military drones and ground vehicles, fusing them into a unified 3D battlefield map2

2

. CEO and co-founder Lukas Köstler describes this as "like a mini map, how you would know it from a strategy game"2

2

. The software sits between raw sensor data and action, connecting drones and ground vehicles from different manufacturers into a shared environmental picture1

1

. On top of this map, SE3 layers object recognition and relational understanding, enabling soldiers to query the system in plain language: "How do I reach a target without being seen?" or "What's a good route for a heavy vehicle?"2

Voice-Commanded Swarm Coordination and Navigation Without GPS

Operators command the system entirely by voice rather than using joysticks or tablets1

1

. A soldier can simply say, "I need reconnaissance two kilometers in the north over the forest," and a suitable drone will autonomously take off, execute the mission, and report back2

2

. The software optimizes each system's behavior, routes, and positions based on terrain, enabling swarm coordination across multiple autonomous systems1

1

. Critically, all processing runs on edge devices, allowing military drones to operate in contested environments where electronic warfare jams satellite navigation1

1

. Köstler, who previously worked on Tesla's Autopilot team and at Nvidia Research, confirmed that navigation without GPS has been delivered thousands of times and is "very robust"2

Deployed in Ukraine and Bundeswehr Contracts

SE3's technology is already deployed in Ukraine, where the company holds multiple contracts and has shipped thousands of systems over the past two years1

2

. The startup also works with Germany's Bundeswehr to develop high-level fleet command AI, though Köstler notes this capability "still needs to be built out over the next one or two years"2

2

. SE3 counts defense prime HENSOLDT, drone software company Auterion, and drone developer ERC System among its partners, with its software running on Auterion's Skynode computers1

Computer Vision Algorithms Power Spatial Intelligence

SE3 does not rely on general-purpose large language models to understand physics or terrain2

2

. Instead, the company uses classical computer vision algorithms to distill vast amounts of sensor data into a database that a language model can query. The model operates within a harness equipped with conventional software tools—if it needs a flight path, a conventional planning algorithm calculates one while avoiding mountains or enemy lines of sight2

2

. Simply feeding raw data to the model "wouldn't work at all," Köstler explained2

2

. Actions such as drone takeoff can require human operator approval, the system runs entirely offline, and customers can swap in their preferred frontier AI model2

Technical University of Munich Spin-Out Tackles Defense Interoperability

SE3 spun out of Professor Daniel Cremers' computer vision lab at the Technical University of Munich, where co-founders Lukas Köstler and Simon Klenk completed their PhDs1

2

. Cremers, who serves as SE3's chief science officer, holds TUM's chair for computer vision and AI and won the Leibniz Prize, Germany's most prestigious research award1

1

. The company's platform-agnostic approach addresses European procurement's shift toward modularity and interoperability through frameworks such as the Modular Open Systems Approach and Germany's MOSABw programme1

1

. SE3 bets that militaries want AI software independent of any single hardware maker, avoiding vendor lock-in that emerges within two or three years when drone makers control their own software stacks2

Expansion Plans Target 120 Employees and European Offices

SE3 plans to use the Series A funding to grow from roughly 40 employees to about 120, investing in engineering, commercial, and operations hires1

2

. The company will open offices in London, Berlin, the Nordics and Baltics, and Poland, while deepening its presence in Germany and Ukraine1

2

2

. Accel partner Matt Robinson stated that SE3's team is "uniquely qualified to take on the challenge of building spatial AI for autonomous systems—something defense primes have found so difficult to do"2

2

.

Future Applications in Robotics and Emergency Response

Defense will drive revenue for at least the next 12 months, but a small team will begin exploring civilian robotics applications2

2

. From 2027, SE3 plans to apply its spatial intelligence layer to robotics, emergency response, and other scenarios where machines must cope with unpredictable environments1

1

. The EU aims to mobilize €800B in defense spending by 2030 and is planning a drone wall along its eastern flank—a wave of capital that has already produced Helsing's €12B valuation and Stark's rise to €3.5B in two years1

1

. As a German company, SE3 operates under strict export laws, with Köstler noting that "it's really the elected parliament that decides in the end what we will do"2

2

. SE3 serves European NATO members and their allies2
