While scholars have analyzed the emergence and characteristics of social enterprises, and their internal tensions between conflicting logics, we have little understanding of the dynamics at the interorganizational level between social enterprises. Based on an in-depth, qualitative study with work integration social enterprises in the secondhand clothes industry, we uncover the dynamics of simultaneous cooperation and competition. Our analysis shows that social enterprises simultaneously—rather than sequentially—engage in coopetitive actions at three levels of action: operational, stakeholder, and environmental interface. At each level, social enterprises engage in different coopetitive actions that do not easily fall under the commercial–social tension usually studied in the social entrepreneurship literature. Social and economic goals motivate both competition and cooperation, but we argue that this plays out differently at each level of coopetition. We conclude with implications for theory and practice.
