I have known Johannes for years, and he is one of the smartest people I have ever worked with. Independent of the context he is able to understand a new topic quickly and deeply, and use his analytical and people skills to come to a structured solution fast. Recently, I had a big decision to make and my thinking was going in circles. Only one conversation with Johannes helped me to get the clarity and insights I needed to become crystal clear on what I needed to do. I would always hire him again on the spot.
