This book focuses on the growing need to have business with purpose. Most books that deal with Social Entrepreneurship Ventures, unfortunately still focus on non-profits and current market trends indicate these types of organizations need more sustainable funding mechanisms. In addition, the growing role of the private sector, as highlighted by the UN Sustainable Development Goals, all emphasize the need to relook entrepreneurship from a 'business with purpose' lens. The fact that venture capitalists/private equity firms are acquiring social ventures (like Bain Capital and Toms) or thinking of divesting them (L'Oreal and Body Shop) perhaps highlight the need to understand the business models that work and some caution areas. One of the biggest barriers for growth of SEV is scalability and internationalization. This book fills the present gap between research and practice; non-profits and hybrid and for-profit firms. It incorporates primary research on scalability of social entrepreneurs, based on some findings from a National Research Foundation Grant.Peppered with short cases from around the world and some short pieces from thought leaders, each chapter in the book ends with thought provoking questions and sources for further reading are presented as relevant footnotes.
