Pillars of our concept

tamanguu’s concept is based on several pillars.


A successful career in the music industry is not possible without a strong network and valuable relationships. In-depth experiences of the practical work derive from more than a decade of work experience in the music business and as an entrepreneur as well as the knowledge from numerous interviews with experts. The theoretical basis is the Ph.D. thesis of tamanguu co-founder Dr. Johannes Ripken about developing a long-lasting artist career in the music business, including a major chapter on networking, relationship management and business network development.
