Back 1998, he founded INTES, the first company focused on consulting and qualification for business families in Germany, and developed it into the leading brand in its segment. In 2013, he sold INTES to PwC. Since then, he has worked as a strategic consultant and in joint projects with PwC and INTES.

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. With the Business Owner Success Forum at Schloss Bensberg (since 1998), he has also created one of the most important conferences for family business owners. Peter May is President of the Governance Commission, Jury Chairman of the Family Business Owner of the Year and Managing Director of FBN Deutschland.

Peter May is also an author and the publisher of numerous publications on the topic of family businesses. His standard works, Erfolgsmodell Familienunternehmen [Family Businesses as Models of Success] and Die Inhaberstrategie im Familienunternehmen [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.”

Karin Ebel is a member of advisory boards and a sought-after speaker at conferences and events for business owners, both in Germany and abroad.

Her guiding principle is: “I have long and repeatedly been fascinated with the tension between family and enterprise. Mingling factual and emotional topics often casts families into a whirlwind of unanswered questions and misunderstandings – causing them to suffer as a result. 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 passion and my contribution to our business families.”
