Ralf Koenzen

Founder & Managing Director

Ralf Koenzen (born 1965) founded LANCOM Systems in May 2002.

Ralf Koenzen started his professional career in 1984 with the founding of the Höffken & Koenzen Datakommunikation GmbH in Mülheim an-der-Ruhr, Germany. Eight years later in 1992, he joined ELSA in Aachen as department manager of ISDN development.

 

ELSA proved to be the springboard for his subsequent career. After three years in 1995, he took over the management of the business unit Communication Systems. The management buyout of this business unit from ELSA AG in 2002 laid the foundation stone for LANCOM Systems.

 

Since then, Ralf Koenzen stands for the success story of LANCOM Systems. His many years of experience and his expertise are instrumental in the strategic development and innovative capabilities of the German network-technology manufacturer.

In 2014, Ralf Koenzen was a finalist in the “Entrepreneur of the Year” award, gaining recognition as one of the Germany's most successful business personalities. Since July 2018, he not only manages LANCOM’s business activities, but has also been heading the “Networks & Cybersecurity” division of Rohde & Schwarz GmbH & Co. KG.

 

Ralf Koenzen studied Computer Science at the University of Dortmund, Germany. He is married and has two children.
