| Description | Venture Capital Firm |
Kleiner Perkins Caufield & Byers (KPCB) is a well known Silicon Valley venture capital firm, due in large part to their past success. They were early investors in many significant companies, including Amazon, AOL, Compaq, Electronic Arts, Google, Intuit, Macromedia, Netscape, Segway, and Sun Microsystems.
The name of the firm comes from the four founding partners: Eugene Kleiner, Tom Perkins, Frank J. Caufield, and Brook Byers.
In March 2008, KPCB announced the iFund, a $100M investment initiative focused on ideas and products related to the iPhone.
