On June 22, 2026, the first ESB Golf Trophy took place at the storied Golfclub Bergisch Land in Wuppertal, and Jonas Onstein, founder of zwoelfstein, was there as a guest of the networking event. Organized by our partner ESB Netzwerk with support from Deutsche Golf Sport GmbH.
The event offered a perfect mix of sport and networking: a tournament in Florida Scramble format at a course that first opened in 1928, a taster session for (not yet) golfers, and a first-class dinner on the clubhouse terrace — including an awards ceremony and networking in a relaxed atmosphere.
