Oscar Salazar is the CEO and Co-Founder and CitiVox, a message board for the mobile web designed to bring communities together. He’s also a Co-Founder of Uber, the successful on-demand private car service. He has a PhD in Telecommunications from the École Nationale Supérieure des Beaux-Arts in Paris, France.

CitiVox began as a service that allowed governments to use mobile and crowd-sourcing technology to build and enhance relationships with citizens; based in Mexico, it served clients in Latin America and Africa. It has since developed into a social platform that asks, “What’s positive about the place where you live?”
