Paul Buchheit is an American computer programmer and entrepreneur. He was the creator and lead developer of Gmail, which anticipated many aspects of Web 2.0, including the idea of Ajax, long before that term was coined. He developed the original prototype of Google AdSense as part of his work on Gmail. He also suggested the company's now-famous motto "Don't be evil" in a 2001 meeting on company values.
Buchheit grew up in Rochester, New York and went to college at Case Western Reserve University in Cleveland, Ohio. He worked at Intel and later became employee #23 at Google.
He is currently an angel investor and a founder of the startup FriendFeed.
