Bill Joy joined KPCB in 2005 as a Partner in KPCB’s Greentech Practice. He helped develop KPCB’s strategy for addressing the twin problems of climate change and sustainability. Joy was previously a founder and Chief Scientist of Sun Microsystems.
Before co-founding Sun, Joy designed and wrote Berkeley UNIX, the first open source operating system with built-in TCP/IP. In 1995 he installed the world’s first citywide WiFi network in Colorado. His many contributions were recognized in a FORTUNE cover story that called him the “Edison of the Internet.”
