1/Tech 1: Carlos Slim Helu
Carlos Slim Helu rocks the top of the chart for the fourth year in a row. His estimated net worth of $73 billion is a full $4 billion more than it was just one year ago. While his portfolio appears to be pretty heavily diversified, he qualifies as a techie by virtue of his Latin American mobile telecom company, America Movil, in which he currently holds a stake worth approximately $36.3 billion. The company also has acquired holdings in KPN Dutch Telecom and Telekom Austria. According to Forbes, he holds no executive positions in any of the companies that he controls, yet remains engaged in an advisory capacity.
