Social entrepreneurship has been attributed many qualities, and hijacked to serve different political and academic agendas. This research attempts to understand how value is created through the organisational build-up, by the study of a NGO in Senegal conducting socially entrepreneurial activities. It points to the incorporation of the target group in the value chain - both as a producer of social impact and a supplier of the strategic information for the organisation - as the main influence of an organisational trait on social value creation. It also points out the importance of a clear value statement, and the production of different types of legitimacy with different stakeholders matching the activities performed. Finally further research areas are suggested, in order to understand the phenomenon of social entrepreneurship in developing countries.
