Social enterprises are recognized for their potential to contribute innovative solutions for intractable social problems, yet little is known about conditions that enable their growth. By following a cohort of social entrepreneurs over a period of 2-3 years, this paper unpacks drivers of social enterprise growth and impact. Based on existing research, we propose that social enterprises in resource-poor environments lack the financial and human capital to scale up their ventures (DiDomenico et al. 2010). We also propose that, similar to mainstream commercial firms, leadership skills positively influence the growth of social enterprises.
