A 38-year-old philanthropist and entrepreneur who founded Toms Shoes (originally Shoes for a Better Tomorrow) in 2006. The concept: donate one pair of shoes to a child in need for every pair sold. The idea was so successful that the company has since expanded into eyewear (a pair of glasses helps pay for eye care in the developing world) and coffee (each bag supplies a week of clean water to a family in a coffee-producing region). Mycoskie was one of the first to extol the virtues of Benefit Corporation status, a designation for companies considering societal or environmental impact. It’s a path since followed by everyone from gear and apparel maker Cotopaxi, which funds nonprofits with every item sold, to Biolite, which distributes a larger version of its biomass-burning camp stove to communities that would otherwise rely on dirtier fuels.
