CEO of Apple (AAPL)
Net worth: $8.3 billion
Apple CEO and co-founder Steve Jobs operates as both creative guru and shrewd businessman.

The majority of revenue comes from music distribution and mobile devices (iPhone and iPad). In the past year, Apple shares have jumped by 80 percent and last May Apple topped Microsoft as the most valuable tech company. But only half of Jobs' fortune comes from Apple. As Disney's (DIS) largest shareholder, he owns about $4.4 billion in Disney stock.
