Names & Facts

adreko was founded in 2002 by Dirk Niedernhöfer, Peter Liebetrau and Bettina Trebbau. The goals were to design, optimise and develop a high quality and legally secure address control system for direct marketing, detecting address theft and illegal use. In 2003, adreko took over seed address management for the migration data of Deutsche Post Adress, a joint venture of Deutsche Post and Bertelsmann. Very quickly, other renowned companies from the mail-order and direct marketing sectors followed. Soon other sectors discovered this “warning system for your addresses” for themselves and their own data.


A couple of address scandals in well known German enterprises and a few amendments of the German Federal Data Protection Act later, the company, now under the management of only two share holders, Niedernhöfer and Liebetrau, has turned into a flexible service provider that evolves with their customers. adreko supports and advises companies about data and address protection, quality control, market research and competitive intelligence.
