CEO and President, Synchrony Financial, 57
Thirty-six years ago, Keane began her career working as a collector at a call center. Today she is the CEO of Synchrony, a major consumer financial services company that is the largest provider of private-label credit cards in the U.S. If you’re not familiar with Synchrony, that’s because it fully split off from former parent GE only in November 2015—a process that Keane oversaw. As of the end of 2015 the company had almost $84 billion in assets, including $29.7 billion in direct deposits, an increase of 50.8% over 2014.
