SE3 Raises €27Mn Series A Funding Led by Accel to Expand Spatial AI Technology Across Europe

Munich-based spatial intelligence company SE3 has raised €27.04 million ($30 million) in a Series A funding round. The company develops technology that helps autonomous systems understand and navigate their surroundings.

SUMMARY

  • SE3 raised €27.04 million ($30 million) in a Series A funding round.
  • The round was led by Accel, with participation from Keen, Lakestar and Seedcamp.
  • Founded in 2023, the Munich-based startup develops spatial AI technology for autonomous systems.

The funding round was led by Accel, with participation from Keen, Lakestar and Seedcamp. SE3 plans to use the new investment to expand its engineering, sales and operations teams to support its growing business and fulfil more customer contracts.

The company also plans to strengthen its presence in Germany and Ukraine while opening a new office in the UK. It aims to expand its operations across more European markets as it continues to grow.

Lukas Köstler, CEO and co-founder of SE3, said, “Working in defence means our technology has to deliver under pressure in the field. We keep that responsibility front of mind in everything we do, working closely with the people who rely on our systems when it matters. Ultimately, today’s funding will get us closer to providing the spatial intelligence technology needed across Europe to protect a free and secure future.”

Matt Robinson, Partner at Accel, said, “With exceptional talent from one of Europe’s leading research departments, the SE3 team is uniquely qualified to take on the challenge of building spatial AI for autonomous systems – something defence primes have found so difficult to do. We’re delighted to back Lukas, Simon, Daniel and team as they build sovereign spatial intelligence for Europe.”

SE3 was founded in 2023 by Lukas Köstler (CEO), Simon Klenk (CTO) and Professor Daniel Cremers (Chief Science Officer). The company started as a spinout from Professor Cremers' computer vision lab at the Technical University of Munich (TUM). Before founding SE3, Köstler and Klenk were pursuing PhDs in computer vision and robotics at the university. Professor Cremers leads TUM's computer vision and AI department and has received the Gottfried Wilhelm Leibniz Prize, one of Germany's top research awards.

I fixed the unreadable chips and the tight spacing, and I’m checking the result now.

I made the 800×450 px image for Biomatter in the periwinkle color from your logo, with the logo in white at top left.

biomatter.ai only loads through JavaScript, so I couldn’t read its content directly. The site’s tagline is “Protein Architects”, and the other details come from news coverage of the company:

Message: the headline “Engineering proteins for health and sustainable manufacturing”, a line on the Intelligent Architecture™ platform, and chips for chemical biomanufacturing, agriculture, food and life sciences.
Fact cards: the €6.5M seed round led by Inventure and UVC Partners (2024), Top 10 at the EPO Young Inventors Prize 2025, the first fully functional AI-generated enzymes in 2019, and the 2018 founding in Vilnius.

Some outlets give 2019 as the founding year, but the funding announcement and the EPO prize coverage say 2018, so I used 2018.

I’ve adjusted the spacing at the bottom left and am checking the result.

I made the 800×450 px image for SE3 on a dark background with your white logo and blue accents, using details from se3.ai.

Header: your logo and a “NEW · $30M SERIES A · LED BY ACCEL” tag.
Message: the headline “Spatial Intelligence for autonomous systems”, a short mission line, and four boxes for Navigate, Perceive, Effect and Command.
Right side: an illustration I drew of a 3D terrain grid with drone paths converging on a target. It is a stylised graphic, not a real screenshot from SE3.
Details: the three highlights (real time, GNSS-denied, one-to-many), the open-architecture and NATO interoperability line, partners HENSOLDT and Auterion, and the STANAG standards.
Footer: se3.ai, offices in Munich, Berlin, London and Ukraine, and contact@se3.ai.

SE3 is developing spatial intelligence technology that helps machines understand their surroundings, make decisions and perform tasks on their own. The company combines artificial intelligence (AI) with computer vision to help machines process information from sensors and understand the physical world around them.

The company's technology is designed for complex environments where autonomous systems need to work safely and reliably. It also aims to help machines operate in places where satellite navigation systems, such as GPS, may not be available or reliable.
