Intersoft Electronics Group, a leading Belgian provider of advanced radar systems and services, is pleased to announce that IDI, a prominent French private equity firm, has acquired a majority stake in the company. The transaction was completed in close partnership with the existing management team as part of a secondary leveraged buyout.
Founded in 1983, Intersoft Electronics Group — comprising Intersoft Electronics, Intersoft Services, and Advionics — has established itself as a global reference in radar technology. The group designs, manufactures, and deploys cutting-edge radar systems and components for both civil and defense applications, serving a prestigious international client base including Eurocontrol, Raytheon, Thales, and Hensoldt.
With nearly 400 employees and over €60 million in annual revenue, the group has experienced strong growth in recent years, supported by Waterland Private Equity. This partnership enabled the successful launch of breakthrough technologies such as the NGSP (Next-Generation Signal Processor) and NORA (Non-Rotating Antenna), and significantly expanded the company’s global footprint.
“We are grateful to Waterland for their invaluable support over the past years,” said Luc Switten, CEO of Intersoft Electronics Group. “Their strategic guidance helped us scale our operations and bring innovative solutions to market. With IDI now joining us, we are entering a new phase of growth. Their industrial expertise, international network, and entrepreneurial mindset make them an ideal partner for our future ambitions.”
Julien Bentz, Managing Partner at IDI, commented: “We are very pleased to become the majority shareholder of Intersoft Electronics Group. This investment aligns perfectly with our strategy of supporting European industrial champions in niche markets. We look forward to working closely with Luc Switten and his team to accelerate the group’s international expansion and technological leadership.”
The partnership with IDI will enable Intersoft Electronics Group to maintain its current management team and organizational structure while pursuing strategic acquisitions, expanding its global footprint, and delivering high-performance radar solutions that enhance the safety, reliability, and sustainability of air surveillance systems worldwide.
