Biz Stone Net Worth, Age, Bio, Career, Family & Achievements

When we talk about icons of Silicon Valley, there’s always one name that pops up with a slightly more artistic flair—Biz Stone. Best known as one of the co-founders of Twitter, Stone is much more than just a tech entrepreneur. He’s a designer at heart, a storyteller by nature, and a social impact advocate by choice.

As of 2025, Biz Stone is 51 years old and has amassed a net worth of approximately $250 million. But as you’ll soon see, it’s not just the financial success that defines him—it’s the values and creativity that have shaped his journey and the tech landscape at large.

Humble Beginnings in Massachusetts

Christopher Isaac “Biz” Stone was born in Boston, Massachusetts in 1974 and raised in nearby Wellesley. His upbringing was modest; after his parents divorced, he was primarily raised by his mother. Growing up, Biz was always the kid sketching in the margins of his notebooks. He was more into art and storytelling than traditional tech, a trait that would later influence how he approached entrepreneurship.

His early love for design and creativity became the foundation of his future ventures. While some future tech moguls were deep into coding, Biz was immersed in visual storytelling.

A College Dropout with a Designer’s Mindset

Stone took the traditional path at first—heading to college. He attended Northeastern University and then the University of Massachusetts Boston. But in true startup-hero fashion, he never completed his degree.

Dropping out didn’t slow him down. In fact, Stone has often said that his partial college experience helped him think creatively and “color outside the lines.” His approach to technology was never strictly technical—it was about how technology could make people feel, interact, and connect.

First Steps into the Tech World

Before Biz Stone became a household name, he kicked off his career at the publishing company Little, Brown and Company. But it didn’t take long for him to pivot towards the burgeoning world of the internet. In the late 1990s, he moved to Silicon Valley to join Xanga, an early blogging platform. It was at Xanga where Stone first began to grasp the power of online communities and social publishing.

This exposure to the blogosphere would serve as the stepping stone for what came next—and it would be huge.

The Google Chapter and Meeting Evan Williams

In the early 2000s, Stone crossed paths with Evan Williams, fresh off the sale of Blogger to Google. Stone joined Google alongside Williams, where the two worked together on refining Blogger, one of the first major blogging platforms.

This partnership would prove to be career-defining. The chemistry between Williams and Stone was evident, and it wouldn’t be long before they decided to break off and do their own thing.

The Twitter Phenomenon: From Side Project to Global Platform

In 2006, Biz Stone, Evan Williams, and Jack Dorsey co-founded Twitter, initially as a side project within Odeo, their podcasting company. It was supposed to be a simple platform where people could share quick status updates—but it ended up becoming something no one could have predicted.

As Twitter’s Creative Director, Stone’s influence was crucial. He helped shape not only the brand but also its quirky, minimalist culture. His design background played a key role in making Twitter feel both approachable and playful. Features like the 140-character limit, the @ mentions, and even the hashtag movement have Stone’s fingerprints all over them.

By the time Twitter hit the mainstream—being used during presidential elections, revolutions, and even emergency situations—it was clear that Stone had helped craft one of the most influential social platforms of the 21st century.

Stone remained actively involved with Twitter until 2011, helping steer the ship during its formative years before stepping away to explore new ventures.

Beyond Twitter: Entrepreneur, Investor, and Innovator

Leaving Twitter didn’t mean slowing down. If anything, it opened the door for Stone to tap deeper into his creative and entrepreneurial instincts.

In 2011, he revived The Obvious Corporation with Evan Williams, an incubator focused on developing new, world-changing ideas. One of their standout projects was Medium, a long-form publishing platform designed to encourage deeper storytelling and richer discussions than what could fit into a tweet.

Not stopping there, Stone founded Jelly Industries in 2013, launching a Q&A search engine designed to crowdsource answers from your social network. Jelly was later acquired by Pinterest in 2017, proving yet again that Stone had an eye for spotting opportunities that blend technology with human interaction.

He also experimented with other quirky ideas, like Chroma—a search engine focused on colors—and continued backing startups through Obvious Ventures, a fund focused on socially responsible businesses.

Champion for Social Good

Throughout his career, Stone has been a vocal advocate for blending business with positive social impact. He’s always believed that companies can—and should—be a force for good.

He and his wife, Livia, run the Biz and Livia Stone Foundation, supporting causes like education, animal welfare, environmental sustainability, and poverty alleviation. It’s a refreshing perspective in an industry often criticized for putting profit over people.

In 2013, Stone published his memoir, Things a Little Bird Told Me, offering insights into his career, his philosophies on creativity, and his belief in staying humble and kind while chasing big ideas. The book, much like Stone himself, champions the idea that success is about more than just making money—it’s about making an impact.

Biz Stone Today: Family, Boards, and Continued Influence

In 2025, Biz Stone is not just a successful entrepreneur but also a father, a philanthropist, and an advisor to emerging companies. He’s married to Livia Stone, and they live with their son Jacob in Marin County, California.

Stone also serves on the board of directors for several organizations, including Beyond Meat, aligning with his vegetarian lifestyle and environmental values. His involvement with socially conscious companies reflects his belief that businesses can and should contribute to a better world.

The Legacy of Biz Stone

So, what’s the takeaway from Biz Stone’s journey? It’s that you don’t have to be a hardcore coder or a cutthroat capitalist to succeed in tech. Creativity, empathy, and a genuine desire to make the world better can take you just as far—maybe even further.

At 51 years old, with a net worth of $250 million, Biz Stone could easily step away from the spotlight. But true to his nature, he continues to influence the way we communicate, share information, and create purpose-driven businesses.

Whether it’s through launching world-changing platforms like Twitter, investing in next-gen startups, or simply advocating for kindness and social good, Biz Stone has proven that heart and hustle go hand in hand.
