In this chapter, five theses are formulated to frame the concept of social entrepreneurship and to make it fruitful in a sport policy context. The social element, entrepreneurship, and sport are entities forming the point of departure of the analysis. The first thesis concerns the social good and the normative goals of democratic fostering. The second and third theses concern the issue of means and goals, and how this is materialized in the voluntary sector. The last two theses concern the conflictual crossing of boundaries between different sectors in society. The theses are accompanied by a case which contextualizes social entrepreneurship in a Swedish sport policy context.
