Marvin Chow is VP of global marketing at Google. He is also a fast-food connoisseur whose family owned a 7-Eleven while he was growing up.

After a childhood in New Jersey, moving to Boston for college was a shock because he couldn't find a Chick-fil-A and had to resort to getting his favorite sandwich sent via FedEx.

But after living overseas in Korea, Japan and China for years, he realized the offerings are usually better outside the U.S. "For me, McDonald's is like an away-game sport," Chow says. "I very rarely eat McDonald's when I'm home in San Francisco, or even in America."

He also weighs in on being married to a chef and the social impact of brands at scale. "When these brands take a stand on nutrition or economic inequality," he says, "they reach millions and millions of people."
