There has been an unexpected wave of growth in social entrepreneurship globally (Bornstein, 2004). This growth is followed by the number of research in the field. Academic research has been mainly focused on defining what it is, what it does and does not have in common with commercial entrepreneurial activity (Nicholls, 2006). Thus, there has not been many studies related to the business model of social enterprise. Osterwalder & Pigneur (2010) believes that every organization has a business model, regardless the word ‘business’ not used as descriptor. This description includes social enterprise. Social enterprise, not unlike business enterprise, creates and delivers value and it must generate enough revenue to cover its expenses. By acknowledging that social enterprise has a business model, it opens itself to business model innovation with advantages to optimize its operations, deliver more values through effective channels, capture more values through profits and growth and drive innovation. This research is conducted on Indonesia Mengajar, a social enterprise in Indonesia that has no experience in business model design or Business Model Canvas using qualitative methods and interpretive paradigm. Primary data is collected from interviews with Indonesia Mengajar. Secondary data comes from books, articles, journals and websites. The data are analysed with grounded theory method. By completing Business Model Canvas (Osterwalder & Pigneur) complemented with literature review and critical analysis of Indonesia Mengajar, the objective of this research to understand business model of social enterprise can be achieved. From this research it is found that adjustments are necessary for Business Model Canvas to capture the business model of social enterprise and based on the findings, it is concluded how social enterprise creates, delivers and captures value.
