Nathan Tan, Associate Director of Brand Partnerships & Experiences at Cadillac, and Judith Rowland, Senior Manager of U.S. Policy and Advocacy at Global Citizen, discusses their "The Accelerator Series" partnership, which seeks to identify and reward American social entrepreneurs who are tackling the world's biggest problems. Three entrepreneurs will be awarded a small grant to grow their efforts. At Saturday night's Global Citizen Festival right here in New York, one in particular will be honored for her work creating a solar-powered food dehydrator. We also talk more about the concert's mission to get people involved in achieving Global Citizen's goal of ending extreme poverty by 2030. Tickets to Saturday's festival are free if you've completed various charitable endeavors through the Global Citizen website. Performances this year will include Stevie Wonder, Green Day, The Killers, The Lumineers, The Chainsmokers, Pharrell, Andra Day, Alessia Cara, and more.
