Title: President and CEO
Company: Yahoo
Country: USA

A celebrity in her home country, Mayer is starting to step onto the world stage. She was co-chair of the recent World Economic Forum’s annual meeting in Davos, Switzerland. And while Mayer’s turnaround of Yahoo’s (yhoo) domestic operations is a work in progress, its international play, a 24% stake in Chinese e-commerce company Alibaba, remains a bright spot.
