Early Life and Education
Jack Dorsey was born on November 19, 1976, in St. Louis, Missouri. From an early age, he displayed a deep fascination with technology, urban planning, and communication systems. His interest in dispatch systems and real-time messaging laid the foundation for what would later become Twitter. Dorsey attended New York University (NYU) to study computer science but left before completing his degree to pursue entrepreneurial opportunities in Silicon Valley.
Despite not graduating, Dorsey’s self-driven learning and coding expertise enabled him to thrive in the fast-evolving tech landscape. His early career included stints at various tech firms where he honed his skills in software development and system architecture—experience that would soon fuel two revolutionary companies.
Co-Founding Twitter: The Birth of a Global Communication Platform
In 2006, Jack Dorsey co-founded Twitter (now known as X) while working at Odeo, a podcasting company. Inspired by the idea of sharing short status updates in real time—originally conceptualized as an SMS-based communication tool—Dorsey helped launch Twitter as a microblogging platform limited to 140-character messages.
The platform quickly gained traction, evolving into one of the most influential social media networks in the world. It played pivotal roles in global movements, political discourse, and real-time news dissemination. Dorsey served as CEO during multiple tenures—first from 2007 to 2008, then again from 2015 until his resignation in November 2021.

Under his leadership, Twitter expanded its features, improved user engagement, and navigated complex challenges around misinformation and content moderation. Although he stepped down as CEO, Dorsey remains a symbolic figure in the evolution of digital communication.
Founding Block (Formerly Square): Revolutionizing Financial Technology
Parallel to his work at Twitter, Dorsey co-founded Square (now Block, Inc.) in 2009 with Jim McKelvey. The company aimed to solve a critical problem: enabling small businesses to accept card payments easily. At the time, traditional payment processors were inaccessible or too expensive for many entrepreneurs.
Square’s compact card reader plugged into smartphones, democratizing digital payments for millions of merchants. Over time, Block expanded its ecosystem to include Cash App—a peer-to-peer payment service that grew into a financial powerhouse offering banking, investing, and Bitcoin trading.
Today, Block generates significantly higher revenue than Twitter ever did under Dorsey’s leadership. The company continues to innovate in fintech, with a strong emphasis on financial inclusion and decentralized technologies.
Advocacy for Bitcoin and Blockchain Technology
Jack Dorsey is one of the most prominent advocates of Bitcoin and blockchain technology in the tech industry. He believes Bitcoin has the potential to become the world’s single global currency, reducing reliance on traditional banking systems and empowering individuals financially.
Dorsey has integrated Bitcoin deeply into Block’s strategy. Through initiatives like the development of decentralized social media platforms (e.g., Bluesky) and support for open-source Bitcoin projects via the Block subsidiary Spiral (formerly Square Crypto), he aims to foster decentralization across both finance and social networks.
His commitment goes beyond business strategy—he personally holds Bitcoin and has expressed interest in living off Bitcoin alone for extended periods. This ideological alignment with decentralization underscores much of his long-term vision.

Philanthropy and Social Impact
In 2020, Dorsey announced a $1 billion donation—approximately 28% of his net worth at the time—through his Start Small LLC foundation to support relief efforts during the COVID-19 pandemic and other social causes. This made him one of the largest philanthropists in tech relative to net worth.
Funds have been directed toward universal basic income experiments, education, homelessness prevention, and racial justice initiatives. Unlike traditional philanthropy models, Start Small operates transparently, publishing grants and impact metrics publicly online.
This approach reflects Dorsey’s broader philosophy: use technology and capital to create scalable, measurable change.
Leadership Philosophy and Personal Discipline
Dorsey is known for his minimalist lifestyle and disciplined routines. A dedicated practitioner of Vipassana meditation—a form of silent mindfulness retreat—he credits meditation with enhancing clarity, focus, and emotional resilience in high-pressure environments.
He often speaks about the importance of simplicity, craftsmanship, and constraint in product design and leadership. These principles guided the development of both Twitter’s interface and Square’s hardware solutions.
Additionally, Dorsey experimented with extreme lifestyle choices, including fasting regimens and working full-time at both Twitter and Block simultaneously—a testament to his intense work ethic.
Net Worth and Sources of Wealth
As of 2025, Jack Dorsey's net worth is estimated at $4.1 billion, primarily derived from his equity stake in Block, Inc. His wealth also includes former holdings in Twitter and significant investments in Bitcoin and other cryptocurrencies.
While he no longer holds an executive role at Twitter post-2021, his early equity positions ensured substantial financial returns. His continued influence in fintech and crypto innovation positions him as a lasting force in the digital economy.
