“We love family businesses –
working with their owners is our calling and our profession.”


We love family businesses. Working with their owners is our calling and our profession. By helping the owners of family businesses to exercise their entrepreneurial responsibility in an optimal way, we serve not only the interests of our clients, but also society. After all, well-managed family businesses represent the best form of capitalist economic activity.



Our success is founded on five simple values.

A strong team. We are convinced that teamwork makes us better. We complement each other – with our different expertise, experience and personalities.

Expertise. All of our partners are renowned experts in their specialist field. From our own first-hand experience, we are intimately aware of what makes family businesses and their owners “tick.”

Experience. All of us have many years of experience of working with and for business families. Only with the right blend of expertise and experience can a good consultant become a “person who understands families.”

Independence. Freedom from conflict of interest is essential to focusing advice exclusively on clients’ interests. That is why we are not part of any group and never act in any way that could endanger the independence of our advice.

Superior methodology. We all work according to the May Method developed by the company founder. This ensures superior concepts and the consistency of our work.



We have conducted more than 1,000 consulting projects with and for family business owners and business families in recent decades. Satisfied customers and public recognition are important indicators of successful work. With this in mind, we have compiled for you a selection of references.
