This is Prof. Dr. Bernd Skiera, a mentor much sought after.

This is as he is on one hand chaired professor of electronic commerce with main research focus on questions like search engine marketing, real-time advertising, social media management, customer management and pricing. On the other hand, he is co-founder of two-companies, Bonpago (www.bonpago.de) and Marini-Media (www.marini-media.de), which both contribute to an even better implementation of his research findings in practice.

Therefor your mentor is an excellent counterpart with a huge knowledge not just theoretically based but also proven in practice.
