More and more women and men are managing to build a reputation as experts outside of traditional career paths and make a good living from it. Until now, there has been neither a systematic approach nor suitable business model tools for these special expert models. In this book, you will find both. Brigitte and Ehrenfried Conta Gromberg unlock the world of smart experts - for those who are already self-employed as well as for those who are just starting out. Learn how to define your own professional expert topic and develop the corresponding business model. The methodology comes from the long-standing practice of the successful solopreneur couple and is illustrated with a high number of case studies.
