How Did Marcos Galperin Build MercadoLibre?

Galperin, the fourth of five sons in a family that owned SADESA, one of the world's largest leather manufacturers, studied finance at the University of Pennsylvania's Wharton School before working for three years at the Argentine energy company YPF. He enrolled at Stanford's Graduate School of Business in 1997, and it was there that he developed the idea for a Latin American version of eBay, founding MercadoLibre in 1999 from a garage in Buenos Aires with a group of classmates.

Galperin secured his first investment after volunteering to drive hedge fund partner John Muse, a guest speaker at Stanford, back to his private plane, a conversation that led Muse to invest in the fledgling company. EBay acquired a 19.5 percent stake in 2001, becoming MercadoLibre's exclusive Latin American partner, and the company listed on NASDAQ in August 2007. EBay eventually sold its stake in 2016 for more than a billion dollars.
