Termin Booker emerged from the course booking platform Course Finder, which was used by a wide range of providers. Through close collaboration with these providers, one recurring request became clear: in addition to courses, individual appointments should also be easy to book. Many course providers also offer coaching, consultations, or one-on-one sessions. Course Finder, however, was only partially suited to cover these needs. This insight led to the idea behind Termin Booker. The goal was to create a standalone, flexible solution dedicated to appointment booking. The experience gained from years of course booking directly influenced the development of the new platform. As a result, Termin Booker was designed to fit the real-world needs of modern service providers.
