This new funding will accelerate Quadsat’s expansion into the defence sector, enabling the company to scale its technology and operations in response to growing demand for battlefield intelligence and electronic warfare capabilities.
Quadsat, a provider of precise spectrum intelligence and RF geolocation solutions for satcoms and defence, has announced a $5.8m extension to its Series A round, led by Join Capital and North Ventures, alongside existing investors Seraphim Space, Export and Investment Fund of Denmark (EIFO), Helge Munk Holding and TPC Management.
This investment enables Quadsat to accelerate its expansion into the rapidly evolving defence sector, enhancing capabilities critical for modern battlefield intelligence and electronic warfare.
Quadsat’s technology, which is platform agnostic, addresses critical defence challenges, including the precise detection and location of RF signals, interference and jamming. These capabilities are increasingly vital for military operations across air, land, sea, cyber and space domains, known in the defence sector as Multi- Domain Operations.
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.”
The global electronic warfare market, driven by increasing geopolitical tensions and rapid technological advancements across the domains of attack, protection and support, is expected to surpass $19.4bn by 2028, growing 12.5% annually.
“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 will use the funds to expand its commercial reach, accelerate product development specifically targeting defense applications, and significantly grow its presence in key NATO member countries. Join Capital, a venture firm renowned for defense and deep-tech investments, emphasised Quadsat’s alignment with urgent defense needs.
“We backed Quadsat because of the clear, strategic edge its RF spectrum monitoring solution delivers,” commented 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.”
North Ventures, a Danish-based venture capital firm known for backing visionary founders, building technology-driven companies, noted the significant market opportunity in Quadsat – particularly as antenna calibration, spectrum analysis, and electronic warfare increasingly form part of critical infrastructure.
Mikkel Rørvig, Partner at North Ventures, remarked: “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.”
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.”
