Larry Page
Co-founder and CEO, Google
Age: 38
Industry: Technology

Since retaking the reins at Google last April, the introverted Page has won praise for making some fast decisions -- and big acquisitions. He's cut back on nonessential projects, while plowing resources into Facebook competitor Google. Ad-driven revenue is stronger than ever -- in July the company reported record-breaking quarterly earnings. But with nearly 30,000 employees across some 30 countries, steering the search giant back to its nimbler roots won't be easy. Even Page recently admitted Google's biggest threat is, well, Google.

Net worth: Page is now worth some $17 billion.
