Owners Club

Building on the success with CEO Clubs and Executive Club, Owners Club offers to its Members a warm and relaxed environment where they celebrate success, learn from mishaps and build strong, long-lasting relationships. As the community is shaped by its Members, we aim to gather together a limited number of business founders and owners with very specific traits and values. Open-minded, thirsty to learn, willing to challenge their assumptions, ambitious yet modest and humane, successful by mentality and with a contribution mindset.
The Club is the place where business challenges are addressed and great ideas and partnerships blossom through sharing of journeys, expert advice and trustful exchange of knowledge and experiences. Business leaders are invited in as the people they truly are, in an environment where respect derives from their personal value and openness to share. This is a Club where people win together.
