TOMS Effect is a teach-in about the unique yet replicable, sustainable, business model created by Blake Mycoskie in 2006: TOMS, a socially-minded, for-profit company that disrupted the business world, and influenced major corporations like Walgreens, Michael Kors, and smaller start-ups like Warby Parker, Brandless, Greenwave, and Bombas to now include a giving component in their sales operations. TOMS also includes vegan shoe product options! Earth Day celebrates innovation in giving, even in the business context. This teach-in will provide an overview of what the TOMS Effect is, as well as a hands-on challenge to innovate a new company that combines both giving and green values. The winning model will receive a TOMS Effect T-shirt!
