Danish defence technology firm Quadsat has completed a €5 million extension to its Series A funding round, targeting enhanced electronic warfare capabilities as global military tensions intensify. The Odense-based company specializes in spectrum intelligence and RF geolocation solutions for satellite communications and defence applications.
Join Capital and North Ventures led the funding extension, with participation from existing backers including Seraphim Space Capital, Export and Investment Fund of Denmark (EIFO), Helge Munk Holding, and TPC Management. The capital injection comes as defence organizations worldwide seek advanced technologies to counter emerging threats in contested environments.
Technology for Modern Battlefield Intelligence
Founded in 2017, Quadsat develops drone-based solutions that identify and locate electronic emitters and signal jamming devices. The platform-agnostic technology enables military forces to monitor threats across air, land, sea, cyber, and space domains—capabilities the defence sector refers to as Multi-Domain Operations.
“Electronic warfare isn’t just critical; it’s an existential necessity in modern defence” said Joakim Espeland, President and co-founder of Quadsat. The company’s technology transforms battlefield uncertainty into actionable intelligence by precisely identifying interference sources and signal disruptions.
The startup’s solutions address both commercial satellite antenna testing and military spectrum monitoring requirements. By locating hostile electronic warfare systems, armed forces can maintain communications integrity and operational awareness in dynamic threat environments.
Real-World Defence Applications
Quadsat’s operational relevance extends beyond theoretical applications. The company maintains a partnership with Skyeton, a UAV provider actively supporting military operations in Ukraine, demonstrating the technology’s value in live conflict scenarios.
“We backed Quadsat because of the clear, strategic edge its RF spectrum monitoring solution delivers” noted Jan Borgstädt, Founding Partner at Join Capital. The investor highlighted the technology’s proven effectiveness in both satellite calibration and operational readiness within contested environments.
The global electronic warfare market reflects growing demand for such capabilities. Market projections indicate the sector will exceed €16.7 billion by 2028, expanding at an annual rate of 12.5 per cent. This growth stems from increasing geopolitical tensions and rapid technological advancement across attack, protection, and support domains.
Expansion Strategy and Market Focus
Quadsat plans to deploy the fresh capital across three primary areas: expanding commercial market reach, accelerating defence-specific product development, and establishing stronger presence within key NATO member countries. The strategic focus acknowledges shifting priorities as defence spending increases globally.
“Quadsat is addressing one of the most urgent challenges in today’s connected world” commented Mikkel Rørvig, Partner at North Ventures. The investor expressed confidence in the company’s international scaling potential amid accelerating global demand.
Klaus Aude, Quadsat’s Chief Commercial Officer, emphasised the company’s evolving market approach. While satellite communications remain important, the defence sector represents dramatic growth opportunities. Current geopolitical conditions create unprecedented demand for solutions that provide certainty in uncertain operational environments.
The funding positions Quadsat to capitalise on increasing defence technology procurement as nations modernise their electronic warfare capabilities. With proven technology and strategic investor backing, the company aims to accelerate deployment timelines for critical defence applications across allied nations.
