Which venture capital firm was founded by Eugene Kleiner and Tom Perkins?

The venture capital firm founded by Eugene Kleiner and Tom Perkins is Kleiner Perkins.

The firm was formed in 1972 in Menlo Park, California. Its original name was Kleiner, Perkins, Caufield & Byers, reflecting four founding partners: Eugene Kleiner, Tom Perkins, Frank J. Caufield, and Brook Byers. The shorter name Kleiner Perkins is now the firm's standard public identity.

Kleiner brought deep semiconductor experience as a co-founder of Fairchild Semiconductor, while Perkins had been an early executive at Hewlett-Packard. Their firm focused on seed, early-stage, and growth investments during Silicon Valley's formative years. It became one of the best-known venture capital firms in technology and was an early occupant of Sand Hill Road.

A common mix-up is treating Kleiner Perkins as if Kleiner and Perkins were the only founders. They supplied the firm's core name, but Caufield and Byers were also founding partners. The firm has backed companies including Amazon, Electronic Arts, Genentech, Google, Netscape, and Sun Microsystems.
