Biz Stone

Christopher Isaac 'Biz' Stone was born in Boston, Massachusetts, in 1974 and worked at Google before joining Odeo as a co-founder. His background in web design and his warm, communications-oriented personality made him Twitter's most publicly accessible co-founder in the early years, serving as the face of the company at conferences, in media interviews, and in its public communications. Stone brought a humanist sensibility to Twitter's development that tempered some of the more technically focused perspectives of his co-founders.

Biz Stone's role at Twitter was primarily in communications, brand building, and public relations rather than in engineering or business strategy, but his influence on the platform's early identity was significant. He published a memoir, 'Things a Little Bird Told Me,' in 2014, offering an insider account of Twitter's founding and early growth. Stone left Twitter after the company went public and co-founded several subsequent ventures including Jelly, a question-and-answer app, and Medium alongside Evan Williams. He later returned to Twitter in 2017 in an advisory capacity for a brief period. Stone has been consistent in crediting the Twitter founding as a genuinely collaborative effort rather than the product of any single genius, offering a more democratized account of the origin story than some other narratives suggest.
