Venture capital mega-firm Kleiner Perkins Caufield & Byers has announced that Mary Meeker is joining the firm as a partner, in another sign that the firm is focusing more on this wave of mobile-meets-social-meets-local-meets-global wave of Web disruption. "Our number one goal is to help the Mark Pincuses of the world build their businesses into Internet treasures, and there has been no greater finder of Internet treasures than Mary Meeker," said KP's John Doerr in an early morning call with TechCrunch, just after Meeker broke the news to Morgan Stanley's technology and Internet practice-- a force on Wall Street where she's made her name over the last 20 years. As an analyst, Mary Meeker was as famous in the dot com glory days as Doerr was as a VC, so it's appropriate and seemingly a long time coming that the two would wind up as partners. Meeker said she'd thought about making the change "from the skybox to coaching down on the field," as Doerr described it, for years. Meeker has been in talks with the firm since late September and made the firm decision to leave Morgan Stanley and join KP the Monday before Thanksgiving. She was swayed finally by a combination of factors including confidence that Morgan Stanley's tech practice was in a strong place, the opportunity with Kleiner specifically and the stage the Internet is in right now.
