Quadsat raises strategic investment to accelerate move into defence market

Danish company Quadsat, which delivers drone-based antenna testing and radio frequency (RF) measurement solutions, announced on 17 July 2025 a EUR 5 million extension to its Series A investment round, led by Join Capital and North Ventures, alongside existing investors Seraphim Space Capital, the Export and Investment Fund of Denmark (EIFO), Helge Munk Holding and TPC Management.

The investment was secured to enable Quadsat, which was established in 2017, to accelerate its expansion into the rapidly evolving defence sector, enhancing capabilities critical for modern battlefield intelligence and electronic warfare requirements. Quadsat will use the funds to expand its commercial reach, accelerate product development specifically targeting defence applications, and significantly grow its presence in key NATO member countries.

“Quadsat’s technology, which is platform agnostic, uniquely 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,” the company explained.

Joakim Espeland, Quadsat’s president and co-founder was quoted as saying in a company press release, “Electronic warfare isn’t just critical; it’s an existential necessity in modern defence. This round is about doubling down. We’ve spent the last year deeply embedded in defence 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 USD 19.4 billion (EUR 16.74 billion), growing 12.5% annually, according to a report by marketing research firm MarketsandMarkets that was cited by Quadsat.

“While the satcoms market remains important for us, we recognise that the defence sector is growing dramatically,” stated Klaus Aude, Quadsat’s chief commercial officer. “The current geopolitical landscape means that defence 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.”
