In last week's newsletter, the central theme was the larger socio-economic role of financial services technology in the fight to end global poverty. MasterCard has certainly been a big proponent of this mission.This week's MasterCard Priceless Elevator in NYC allowed entrepreneurs 60 seconds to pitch their business idea to combat poverty. For each pitch, MasterCard donated $500 to DataKind, an organization that uses data to promote social good and help end poverty.
