The past decade has witnessed a surge of research interest in social entrepreneurship organizations (SEOs). This has resulted in important insights concerning the role of SEOs in fostering social challenges. The crisis of both public and private profit-driven models meet the arising of new initiatives designed to meet the minor and often abandoned cultural heritage consumption need. Drawing on the domain of SEOs and social bricolage framework, these initiatives are able to pursuing the social and the economic mission together and not in a sequential way. This paper aims to analyse how SEOs that use strategies of social bricolage can improve the development and diffusion of social innovation. In this first phase of our research we carried out a comparative case study of fifteen cultural SEOs in the South of Italy. First results show that SEOs in the domain of minor cultural heritage adopt an innovative business model and unravel organizational dimensions falling into the social bricolage. The relation between social bricolage dimensions and social business model criteria produces outcomes in which social innovation can be expressed. Our study enhances current understanding of the social dimensions of business model involved in social innovation production of cultural SEOs. This research aims to be a benchmark of the social innovation initiatives in the field of minor cultural heritage management.
