Leif Rehfeldt and Falko Feßer Jointly Lead: Leadership Duo Strengthens Growth at Deutsche Windguard Systems

Berlin (Germany) - At Deutsche WindGuard Systems GmbH, Leif Rehfeldt assumes the role of Managing Director and will jointly lead the company in the future together with long-standing Managing Director Falko Feßer.

The company, part of Deutsche WindGuard GmbH based in Varel, aims to use the expanded leadership tandem to particularly drive the growth of the Wonder software solution as well as AI-based applications.

Wonder supports operators and asset managers in the technical and commercial management of renewable energy portfolios. The system is complemented by the mobile inspection solution Wonder onSITE, which transfers inspection data directly into the software.

“At our Berlin office, our team of software development experts has been creating success stories for 25 years with the high-performance wind farm management system Wonder,” says Leif Rehfeldt. “With an eye on the global expansion of renewable energies, we are consistently driving forward the strategic development of our software solutions to systematically conquer new markets.”

In addition to further developing the products, a key focus lies on creating tailored AI solutions for internal and external applications within the corporate group. The goal is to open up additional markets in the international renewable energy sector.
