Quadsat Secures €5M To Boost Electronic Warfare Tech

The funding will help Quadsat boost its capabilities in battlefield intelligence and electronic warfare.

The round was led by Join Capital and North Ventures, with support from existing backers like Seraphim Space Capital, EIFO, Helge Munk Holding, and TPC Management.

Joakim Espeland, President and Co-founder of Quadsat, said: “Electronic warfare isn’t just critical; it’s an existential necessity in modern defense. This round is about doubling down. We’ve spent the last year deeply embedded in defense needs, refining a technology that pinpoints threats, like the interference of military installations, which is an absolute game-changer in the field.”

Founded in 2017, Quadsat offers advanced spectrum intelligence and RF geolocation solutions for satellite communications and defense.

Its drone-based tech helps detect jammers and signal emitters, giving armed forces real-time battlefield awareness.

The platform works across air, land, sea, cyber, and space—supporting modern Multi-Domain military operations.

“Join Capital and North Ventures are on this journey because they see the strategic value in our solution and the vision our team has been pursuing relentlessly,” Espeland added. “In electronic warfare, clarity saves lives. Our drone-agnostic tech is all about turning battlefield chaos into actionable intelligence.”

Quadsat’s collaboration with UAV provider Skyeton—currently supporting missions in Ukraine—demonstrates its role in strengthening operational resilience and enhancing intelligence in active conflict zones.

“We backed Quadsat because of the clear, strategic edge its RF spectrum monitoring solution delivers,” said Jan Borgstädt, Founding Partner at Join Capital. “From satellite calibration to operational readiness in contested environments its solution is already proving its value in real-world defense scenarios. We believe Quadsat will define the next generation of spectrum intelligence.”

The global electronic warfare market is projected to exceed €16.7 billion by 2028, growing at an annual rate of 12.5%, fueled by rising geopolitical tensions and fast-paced innovations in attack, defense and support technologies.

Mikkel Rørvig, Partner at North Ventures, commented: “Quadsat is addressing one of the most urgent challenges in today’s connected world – with a truly game-changing solution. Its technology is already delivering real impact, and with global demand accelerating, we see enormous potential in scaling Quadsat internationally. We’re proud to support the team on this journey – alongside the strong co-investors.”

Quadsat will use the funding to grow its commercial footprint, speed up product development for defense use, and strengthen its presence in key NATO countries.

Klaus Aude, CCO, Quadsat, concluded: “While the satcoms market remains important for us, we recognise that the defense sector is growing dramatically. The current geopolitical landscape means that defense organisations, more than ever, need solutions that can make the uncertain certain. We have the technology, and this latest investment round will enable us to get it to those actors faster.”
