Early Life

Born in 1974 in Boston, Massachusetts, Biz Stone—whose real name is Christopher Isaac Stone—was raised in Wellesley by a single mother after his parents’ divorce. His early love for art and design would later shape his creative approach to technology and product development.

Stone attended Northeastern University and later transferred to the University of Massachusetts Boston, but he did not complete a degree. Instead, he jumped straight into the tech world, a decision that ultimately helped build his fortune.

The Path to Twitter

Stone started his career at publishing house Little, Brown and Company, then moved into tech during the dot-com boom by joining the blogging platform Xanga. In 2003, he joined Google, where he worked with Evan Williams—his future co-founder at Twitter—on the blogging service Blogger.

In 2006, Stone teamed up with Williams and Jack Dorsey to launch Twitter, a microblogging platform that would go on to change global communication. As Twitter’s Creative Director, Stone played a critical role in shaping its identity, including features like hashtags and the @ symbol.

Stone stayed with Twitter through its early explosive growth and became a public face for the company. His share of the company’s success contributed significantly to his current net worth.

Ventures Beyond Twitter

After stepping away from Twitter in 2011, Stone co-founded The Obvious Corporation, an innovation lab where he and Evan Williams developed new ideas. One of their most notable ventures was Medium, a platform for long-form articles and storytelling that has grown into a major content hub.

In 2013, Stone launched Jelly, a Q&A search engine later acquired by Pinterest. He also founded Chroma, a search engine based on color, and invested in startups through Obvious Ventures, which supports companies that combine profit with social impact.

These ventures, along with his early Twitter stake and successful exits, have helped Stone maintain and grow his $250 million fortune.

In 2013, he published a memoir, Things a Little Bird Told Me, where he shared his philosophy on creativity, opportunity, and using technology for good.
