Quadsat Raises €5 Million to Advance Electronic Warfare Capabilities

New investment supports the company’s expansion into defense and NATO-aligned markets

Strategic Investment to Accelerate Defense Expansion

Odense, Denmark-based Quadsat has announced a €5 million extension to its Series A funding round. The new investment is led by Join Capital and North Ventures, with continued support from Seraphim Space Capital, the Export and Investment Fund of Denmark (EIFO), Helge Munk Holding, and TPC Management.

The funding will help Quadsat expand its spectrum intelligence and RF geolocation solutions for the defense sector. The company plans to grow its presence in NATO countries and focus on military applications, including interference detection and jamming protection.

Meeting the Needs of Multi-Domain Operations

Quadsat’s platform-agnostic technology is designed to locate and analyze RF signals. These capabilities are becoming more critical as defense organizations operate across land, sea, air, cyber, and space. Known as Multi-Domain Operations, these missions require precise signal intelligence to ensure operational readiness.

Quadsat began in 2017 with a focus on satellite antenna testing. Today, the company serves major satellite operators like SES and OneWeb. It also partners with UAV provider Skyeton, which supports field operations in Ukraine.

“Electronic warfare isn’t just critical; it’s an existential necessity in modern defense,” said Joakim Espeland, President and Co-Founder of Quadsat. “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.”

Growing Global Demand for Spectrum Intelligence

The global electronic warfare market is projected to exceed $19.4 billion by 2028, growing at 12.5% annually. As global tensions rise, the need for secure, accurate spectrum monitoring is becoming essential.

“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 said. “In electronic warfare, clarity saves lives. Our drone-agnostic tech is all about turning battlefield chaos into actionable intelligence.”

Investors Highlight Quadsat’s Market Potential

Jan Borgstädt, Founding Partner at Join Capital, said, “We backed Quadsat because of the clear, strategic edge its RF spectrum monitoring solution delivers. 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.”

Mikkel Rørvig, Partner at North Ventures, emphasized the broader opportunity: “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.”

A Dual Focus on Satcom and Defense

While Quadsat continues to support commercial satellite customers, the company is placing increased emphasis on defense. “The current geopolitical landscape means that defense organisations, more than ever, need solutions that can make the uncertain certain,” said Klaus Aude, Quadsat’s Chief Commercial Officer. “We have the technology, and this latest investment round will enable us to get it to those actors faster.”
