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 cooperation with the existing management team as part of a secondary leveraged buyout.

Founded in 1983 — and consisting of Intersoft Electronics, Intersoft Services, and Advionics — Intersoft Electronics Group has established itself as a global reference in the field of radar technology. The group designs, manufactures, and implements advanced radar systems and components for both civil and defense applications, serving a prestigious international clientele that includes Eurocontrol, Raytheon, Thales, and Hensoldt.
With nearly 400 employees and an annual turnover of over €60 million, the group has experienced strong growth in recent years, supported by Waterland Private Equity. This partnership enabled the successful launch of groundbreaking technologies such as the NGSP (Next-Generation Signal Processor) and NORA (Non-Rotating Antenna), and resulted in a significant expansion of the company’s global presence.
“We are grateful to Waterland for their invaluable support over the past years. Their strategic guidance helped us scale our operations and bring innovative solutions to the market. With IDI joining us now, we are entering a new phase of growth. Their industrial expertise, international network, and entrepreneurial mindset make them the ideal partner for our future ambitions.” — Luc Switten, CEO of Intersoft Electronics Group.
The partnership with IDI allows Intersoft Electronics Group to retain its current management team and organizational structure while pursuing strategic acquisitions, further expanding its global presence, and delivering high-quality radar systems that contribute to the safety, reliability, and sustainability of air traffic control systems worldwide.
“We are delighted to become the majority shareholder of Intersoft Electronics Group. This investment aligns perfectly with our strategy to support European industrial champions in niche markets. We look forward to working closely with Luc Switten and his team to further accelerate the group’s international expansion and technological leadership.” — Julien Bentz, Managing Partner at IDI
