The thesis originates from a business idea and forms the foundation of a start-up. The business idea aims to match and facilitate people in Switzerland based on shared interests for joint activities/events combined with regular appointment scheduling via a digital platform. The underlying problem addressed by this solution is the lack of in-person social contact/interaction of people in Switzerland. The study shows that this is a problem worth solving as the consequences are far-reaching and, in many cases, endanger physical and mental health. By developing a clear problem-solution-fit, the thesis shows that these problems can be solved with a digital solution in the field of (joint activity/event) scheduling. With the developed but still expandable product-market-fit, it is shown that there is a demand for such a digital solution in Switzerland, which is currently not served by existing solutions. All in all, there is a business opportunity in Switzerland in the field of scheduling and joint activity/event scheduling as a combined service. The business concept and the prototype show how this business opportunity can best be used/served and that it is economically profitable.
