Founder, Tiger Global Management

Charles Payson Coleman III may have descended from Peter Stuyvesant (the last Dutch governor of New York, who built the "wall" in Wall Street), but it's his new-school approach that has made him hugely successful. His $6.5 billion Tiger Global hedge fund gained 45% last year (tops among hedge funds its size, beating luminaries like John Paulson, Louis Bacon, and David Einhorn) on holdings in companies like Apple. His so-called private funds--a mix of venture capital and private equity-like investments--were boosted last year by stakes in then-private Facebook and LinkedIn. The fund is up another 21% so far this year. The firm sold almost $1 billion worth of Facebook stock during the IPO (about half his stake), once again proving his savvy.

¿Cómo se dice dinero? Coleman studied Spanish and economics at Williams College.
