Best known as one of the co-founders of Twitter, Stone helped create one of the world’s most influential social media platforms. Beyond Twitter, he has launched and invested in several successful technology companies, including Medium, Jelly, and Obvious Corporation, while also becoming a leading advocate for socially responsible entrepreneurship.

Early Life

Christopher Isaac “Biz” Stone was born in 1974 in Boston, Massachusetts, and grew up in nearby Wellesley. Raised primarily by his mother after his parents divorced, he developed a passion for art, design, and creativity from an early age—interests that would later influence his work in technology.

After graduating from high school, Stone attended Northeastern University before transferring to the University of Massachusetts Boston. Although he did not complete his college education, he left school to pursue opportunities in the rapidly growing technology sector.

Early Career

Stone began his professional career in publishing at Little, Brown and Company before relocating to Silicon Valley during the internet boom of the late 1990s.

He joined blogging platform Xanga, where he gained valuable experience in online publishing and digital communities. His career took a major step forward in 2003 when he met entrepreneur Evan Williams, who had recently sold Blogger to Google. Stone joined Google and worked alongside Williams on Blogger, helping improve one of the internet’s earliest blogging platforms.

The partnership would later lead to one of the biggest social media success stories in history.

Co-Founding Twitter

In 2006, Stone teamed up with Jack Dorsey and Evan Williams to launch Twitter, a platform that transformed online communication through short, real-time messages.

As Creative Director, Stone played a key role in shaping Twitter’s identity, design, and user experience. He helped establish many of the platform’s defining features, including mentions, hashtags, and the concise posting format that became Twitter’s trademark.

During Twitter’s rapid global expansion, Stone frequently represented the company at conferences, interviews, and public events, becoming one of its most recognizable executives. He remained actively involved until 2011 as Twitter evolved into one of the world’s leading social networking platforms.

Business Ventures Beyond Twitter

Following his departure from Twitter’s day-to-day operations, Stone continued building new technology companies.

In 2011, he reunited with Evan Williams to relaunch Obvious Corporation, an innovation studio focused on developing new digital products and investing in mission-driven startups.

A year later, the pair co-founded Medium, an online publishing platform that encourages long-form storytelling, commentary, and professional writing. Medium has since become one of the internet’s leading destinations for writers, journalists, and industry experts.

Stone also launched Jelly in 2013, a social search platform that allowed users to ask and answer questions through their networks. Pinterest later acquired the company in 2017.

In addition to founding startups, Stone has invested in numerous emerging technology businesses through Obvious Ventures, a venture capital firm focused on companies that combine financial success with positive social impact.

Philanthropy

Throughout his career, Stone has emphasized that businesses should create value beyond profits.

Together with his wife, Livia, he established the Biz and Livia Stone Foundation, supporting charitable initiatives focused on education, environmental conservation, animal welfare, and poverty reduction.

Stone has also served on the boards of several organizations and companies, including Polaroid and plant-based food company Beyond Meat, reflecting his long-standing commitment to sustainability and ethical business practices.

In 2013, he published his memoir, Things a Little Bird Told Me, where he shared lessons from building Twitter and discussed the importance of creativity, optimism, and purpose-driven entrepreneurship.

Personal Life

Biz Stone has been married to his wife, Livia, since 2007. The couple has one son, Jacob, and they reside in Marin County, California.

Outside the technology industry, Stone remains involved in startup investing, public speaking, philanthropy, and mentoring entrepreneurs, continuing to influence the next generation of innovators while supporting businesses that aim to make a positive impact on society.
