Technology analyst Mary Meeker is leaving Morgan Stanley to join Kleiner Perkins Caufield & Byers, a venture capital firm that backed browser pioneer Netscape Communications in 1994 and search giant Google in 1999.

Meeker, who will be a partner, "brings extraordinary expertise to help guide and accelerate the success of social, mobile and new commerce internet companies,'' Kleiner said in a prepared statement.

At the Web 2.0 conference in San Francisco earlier this month, Meeker forecast that the sale of smartphones will top the sale of personal computers and laptop computers -- combined -- two years from now. Floor brokers at the New York Stock Exchange, for instance, can now send orders wirelessly, for execution at a new data center in Mahwah, N.J.

“KPCB has a long and exceptional track record of helping entrepreneurs build world-changing ventures and launch new industries,” said Meeker, in the statement. “We’re at the beginning of another great wave of tech innovation and I am incredibly excited by the opportunity to help the next generation of Internet technologies and leaders.”

Meeker first rose to investment industry fame with a 1995 tome called "The Internet Report" and has led Morgan Stanley's Global Technology Research team.

“Mary was an early supporter of some of the biggest technology investment winners of the past 20 years,” said KPCB partner John Doerr, who led the investment in Netscape. “Her advice and support are already highly sought after by entrepreneurs and in this new role, she will be able to spend even more time providing more direct assistance.”

Meeker will be based in Silicon Valley. She joined Morgan Stanley in 1991.

Among Kleiner's Internet investments have been AOL, Amazon, Google, Netscape, Sun Microsystems, Verisign and Zynga.
