Social cohesion belongs among the current problems of the European Union. Although there are spent considerable financial support to this area, so there are still significant social differences between regions of the European Union. Social enterprises are one of the social innovations that seek to address this issue not only through short-term financial support. The nongovernmental organizations have a major impact on the creation of social enterprises. The aim of this paper is to evaluate the effectiveness of financial support for social enterprises, which were financially supported by the ESF in the period 2007-2013. Evaluation will be done by measuring the index of social return on investment (SROI).
