CEO and President, Progressive, 51
Griffith became CEO of the nation’s fourth-largest auto insurer in July. It’s an impressive run for the onetime claims rep, who worked her way up through a number of business segments and most recently served as COO of Personal Lines. Griffith takes the reins at a time of transition, as Progressive attempts to redefine itself as more than just a car insurance company. She was a driving force behind the company’s expansion into home coverage. If she can persuade customers to buy multiple policies from Progressive, that move could pay off.
