Experience gathered. Accolades received.


We began our activity in 2008. In the meantime, we have risen to become one of the biggest independent consultancy institutes. We serve numerous well-known clients of various sizes throughout Germany. Both internationally operating corporations and large institutions and municipalities make use of our services. In January 2014, we were named the biggest business partner of Telefonica O2 in Munich. In the years prior to that we were in third and second place.

Seidel & Friends Consulting has been one of O2’s biggest partners for several years. In addition, we count as one of the “Business Premium Partners” of Deutsche Telekom AG and are one of its ten biggest partners nationwide. We have also been awarded the title “Business Partner Gold” by Vodafone every year since 2009. We are therefore one of the most successful partners in the whole of Germany.

Already, over 16,000 business customers trust the competence of our company – and so Seidel & Friends Consulting is therefore currently responsible for more than 9.2 million euros in turnover for its clients with the leading German network providers Deutsche Telekom, Telefonica O2 Germany and Vodafone.
