Josh Opperman, I Do Now I Don't 
The idea for I Do Now I Don't, an online marketplace for used or unwanted engagement rings, was born out of Opperman's own failed relationship. Sellers get above-market returns on unwanted jewelry while buyers get normally high-priced jewelry at a discounted rate. Aside from saving consumers money, Opperman also believes that reusing and reselling unwanted diamonds lessens the environmental impact of diamond mining. To that end, every Earth Day the company gives its users the chance to donate a portion of its profits to an environmental charity of their choice.

Phillip Nappi, founder of Peter Nappi 
Nappi was inspired to create Peter Nappi, a luxury Italian footwear company based in Nashville, Tenn., after discovering that his grandfather (for whom the company is named) shared the same passion for leather craftsmanship. "Our goods are crafted, not produced, and we value traditions over trends," he says. "We've taken old-world styles and made them relevant. Today's consumer wants more than a label. They want an experience; they want to be part of a story." Peter Nappi gave a percentage of its sales during the Christmas season to several charities through their "Ti Voglio Bene" campaign (Italian for "We want you to be well").
