In Chapter 15 of 18 in his 2013 Capture Your Flag interview, entrepreneur and community builder Fabian Pfortmüller answers "What Are the Challenges of Making a Socially Conscious Business Sustainable?" Pfortmüller notes the tradeoff of making a product that sells versus a sustainable product that sells. He notes short term sacrifices that occur given higher prices for sustainable products, but how this gradually erodes as community trust is built with customers as the product stories are shared and embraced. 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.
