Though I haven´t experienced Oliver at OnVista or any other related projects to that company, I just can say, that he is very open-minded and very helpfully in the way he works. He helped me several times thinking through new concepts, finding new business models. He seems to be brilliant in his job - he is brilliant as a friend.
