Biz Stone is co-founder of Twitter, a messaging network changing the way we communicate. For the past decade, Stone has been working on large scale projects that facilitate the open exchange of information starting with social networking and blogging service Xanga in 1999.

Stone has published two books on the origins and social significance of our changing communication landscape and has lectured around the world on this subject as well as others including creativity, opportunity, and positive global change. In 2009, Stone was added to the Time 100-an annual list of the world's most influential people. Originally from Boston, Stone lives with his wife Livia in Marin County California.
