In 2012, Andy Ruben left his executive role at Walmart to start Yerdle and pursue his dream of building the next generation of retail. An online store whose mission is to reduce the durable consumer goods we need to buy by 25 percent, Yerdle allows customers to post pictures of their unused items and swap them for things they want. Before launching Yerdle, Ruben started Walmart’s sustainability effort, reimagining the company’s US$20 billion private brands business, and integrating online and brick-and-mortar stores. Ruben is also a TED speaker who has been featured in NPR’s All Things Considered, the New York Times, and the Wall Street Journal. As one of Walmart’s youngest corporate officers, Ruben also testified before the U.S. Congress as an expert in business and sustainability.
