Gudrun Scharler Appointed CEO of Riedel Networks The Riedel Group today announced the appointment of Gudrun Scharler as CEO of Riedel Networks. She succeeds Michael Martens, who has led Riedel Networks since 2012 and will support a structured handover through the end of August.

Michael has shaped Riedel Networks with exceptional commitment, entrepreneurial spirit, and a clear sense for what customers need, said Frank Eischet, Riedel Group COO. We are deeply grateful for everything he has achieved over the past 14 years. At the same time, we are excited to welcome Gudrun as the new CEO of Riedel Networks. With her strong leadership background in telecommunications, operations, and transformation, she is the right person to guide the company into its next phase of development.

Scharler brings extensive executive experience from leading telecommunications and technology companies, where she has improved operational performance, led customer-focused transformation, and managed complex organizations. Her track record includes key roles at Unitymedia, where she served as Chief Operations Officer, as well as senior leadership positions at Nets Group, E-Plus, Sunrise Communications, and Telef nica Germany. Most recently, she expanded her leadership experience through roles at Canyon Bicycles and P2 eBike GmbH.

Riedel Networks is a great company with a strong team, a clear customer focus, and significant potential for further development, said Scharler. I am very much looking forward to getting to know the team and working together to continue the company's transformation while preserving the flexibility, speed, and collaborative spirit that make Riedel Networks special. I would also like to thank Michael for the open and structured handover and for the strong foundation he has built.

Since assuming leadership of Riedel Networks in 2012, Martens has guided the company through a period of significant growth, helping to scale its business in secure networks and IT security. During his tenure, Riedel Networks grew from 2.8 million in revenue and 12 employees to 24 million and 70 employees.

Riedel Networks has been a defining part of my professional journey, and I am proud of the company we have developed together, said Martens. Gudrun is taking over a company with strong momentum, and I look forward to supporting her as she leads Riedel Networks into its next chapter.
