“Family businesses are the best form of capitalist businesses. But they also require outside impulses to develop their full potential.”


The work we undertake together is based on five basic convictions:

1. Love of family businesses: A love for family businesses forms the basis of our work together. Family businesses are not perfect, but they are the best form of capitalist economic activity.

2. Creating sustainable benefits: We assist owners of family businesses with fulfillment of their entrepreneurial responsibility – from the joint development of concepts to their successful implementation. So your entrepreneurial dream can continue. From generation to generation.

3. A strong team: We work together – because we’re better together, and because we like each other. Each of us contributes his or her personal abilities – for the benefit of our clients, and in the interest of the entire undertaking.

4. Simply better: We place the highest demands on the quality of our work. At the same time, we are “incorruptible,” respectful and, if need be, disruptive.

5. A compelling theoretical foundation: The May Method is the common foundation of our work. Because we are convinced that a world-class theoretical foundation makes the difference. True to the guiding principle: “Theories are like maps. They may not be reality, but they make reality easier to navigate.”

Peter May is an honorary professor at WHU – Otto Beisheim School of Management in Vallendar and has taught at various universities. From 2008 until 2009, he was Wild Group Chair of Family Business at IMD in Lausanne, Switzerland.

Early on, he called for an independent approach to business administration for family businesses. With the INTES Principle, the 3-Dimensional Model, the Owner Strategy and the Family Constitution, he developed important concepts for advising family businesses and business families.

He has also launched numerous initiatives for family businesses. He initiated the world’s first Governance Code for Family Businesses (2004 in Germany and 2005 in Austria) as well as the Family Business Owner of the Year Award (since 2004), the entrepreneurs association FBN Deutschland (since 2000), and the Institute for Family Business at WHU.

His standard works, Erfolgsmodell Familienunternehmen [Family Businesses as Models of Success] and Die Inhaberstrategie im Familienunternehmen – Eine Anleitung [The Owner Strategy in Family Businesses: A Guide], have been translated into various languages.

The areas of focus for Peter May’s work are in in-depth personal support of business-owning families (including advisory and supervisory board activities) as well as taking on difficult and particularly exciting consulting mandates.

His guiding principle is: “Family businesses are my passion. I am happy to have been able to combine this passion with my penchant for sharing knowledge and experience, and to turn my calling into a career. I love my work and everything connected with it.”

It is important to break this vicious circle and give every family member adequate space for his or her concerns. To find shared solutions that will last – for the family and the business. That is my mission and my contribution to our business families – and my passion.”
