Founder identity has been found a popular and useful concept to understand entrepreneurial behaviour. Still, we know little about the interplay and joint influence of different types of founder identities. By analyzing role, social, and personal identities, this study investigates which combinations of those lead to balanced commercial and social welfare logics or the dominance of one or the other in new ventures. To do so, Qualitative Comparative Analysis is employed for 29 cases, integrating qualitative and quantitative data. Results provide the first empirical evidence on the nexus of founder identity and institutional logics, and contribute to our understanding of identity theory in general and founder identity in particular.
