Mr. Dernbach takes a very structured approach. He strikes a balance between the factual and personal aspects of a start-up and brings calm to the topic. He opens up new perspectives with skillful questions, so that the "stress test" for the founding idea is conflict-free and solution-oriented. However, he addresses the problem points openly. He examines the start-up idea for possible alternatives. If there are none or if they do not appeal to the founder, a feasible and sustainably realistic framework for the desired direction is sought. Mr. Dernbach is an authentic, trust inspiring and pleasant consultant. I experienced a rather work-intensive time with him, always felt supported and am very satisfied with the achieved result.
