23. Irene Rosenfeld
CEO, Kraft Foods

Ignoring the protestations of her biggest shareholder, Warren Buffett, Rosenfeld bought British confectionery Cadbury earlier this year in a $19 billion deal that makes Kraft the world's biggest seller of snack foods. The acquisition gives Kraft, whose products already enjoy a 99% penetration rate in U.S. households, access to key markets such as India and China. Rosenfeld anticipates that the combined companies will produce annual revenue growth of 5% or more, and profit margins in the mid to high teens.
