In Chapter 14 of 18 in his 2013 Capture Your Flag interview, entrepreneur and community builder Fabian Pfortmüller answers "How Do You Define Social Entrepreneurship?" Pfortmüller sees a social entrepreneur as one who builds an organization that tries to optimize positive impact by using the traditional means a business structure provides. He shares how his own work at Holstee relates to this definition and the balance he tries to find between making financial ends meet and creating that impact in progressively more measurable ways. Fabian Pfortmüller is co-founder of Holstee, a socially conscious online marketplace, and Sandbox Network, a global community for young entrepreneurial people. Pfortmüller graduated from Columbia University.
