Stephan Meintrup

Managing Partner

"The exciting thing about my job is getting to know new people and businesses and to network with each other. The result is intelligent cooperation of long-term value for all partners in all business areas."

Stephan Meintrup, born in 1967, studied economics and initially worked in the tourism industry. The liberalization of the telecommunications market at the end of the nineties created a new environment for a change into the industry in which he has worked since that time. He worked as a Sales Manager Global Account for MCI WorldCom (now Verizon) and subsequently as an officer and managing director for two TROPOLYS companies (now Versatel), where he also met Detlef Wientgen. Then he initiated SCI, contributing his expertise and network to the new company. Within SCI he is responsible for the development of new business activities. In 2009, he completed his MBA (Master of Business Administration) degree program successfully.

Stephan Meintrup is married and has 2 children.
