What's mine is yours. An increasing number of people are participating in sharing and exchanging information, knowledge, data and goods. As research addressing the so‐called ‘sharing economy’ is still in its infancy, this article aims to shed light on it. To do this, a qualitative research approach comprising guided interviews with 14 companies from Germany, Austria and Switzerland provides detailed insights into different aspects of the sharing economy phenomenon. Our results make a direct contribution to sharing economy research, especially regarding the new business models of start‐ups. Here, we find a clear difference between the relevance of economic and social orientation. The latter appears to be in higher demand among customers than entrepreneurs. The increasingly digitalized environment has led to a changed living situation characterized by urbanity, openness to new solutions, changed working situations and new mindsets. All of these aspects drive the sharing economy. The results of this paper are summarized in a framework highlighting the requirements, drivers and goals of the sharing economy. Considering the limited research in this field, the developed framework is a strong basis for discussion, critique and/or support of future research.
