CEO of Dell
Net worth: $14.6 billion
Dell founder and CEO Michael Dell's net worth saw a slight boost of $1.1 billion last year as Dell increased its revenue by 5 percent after a few bad years. Since returning as CEO in 2007 to turn around a slumping company, Dell restructured his company's divisions, hired new management and continued to push an array of Dell products in the traditional PC space as well as the smartphone and tablet spaces. In late 2009, Dell paid $3.9 billion for Perot Systems (Perot as in Ross Perot) to enhance Dell's IT services portfolio.
