Alfredo Gangotena, the global chief marketing officer of MasterCard Worldwide, oversees a brand with a presence in 110 countries that, he says, touches 1 out of 3 consumers across the globe.

In an interview outside the Majestic Barriere in Cannes, he spoke to Ad Age about how creativity has taken on a life of its own within his company -- and how a long-standing agency relationship can contribute to great work.

Mr. Gangotena also shared how MasterCard is playing an integral role in developing markets -- such as Nigeria, where it is working with the government to provide people with a product that is a national identity card on one side and a credit card on the other.
