(Corrects spelling of Marc Andreessen's name in headline)
In the 15 years since Netscape's initial public offering made him rich, Marc Andreessen, 39, has become a ubiquitous Silicon Valley power broker. He's an entrepreneur, he's an investor, he's hunting CEO candidates for Hewlett-Packard (HPQ). It's hard to keep track.
Netscape, née Mosaic Communications, was only his first act. After AOL (TWX) bought the browser firm in 1998 and then merged with Time Warner, Andreessen departed and has formed a range of companies.

Andreessen Horowitz, the $300 million investment fund he launched a year ago, has already backed a string of apparent winners. The firm is reportedly raising a second, larger fund.

Years before he created his VC firm, Andreessen (who wouldn't comment for this article) was investing in, and mentoring, dozens of startups in all corners of computing.
