'''Jack Patrick Dorsey''' (born November 19, 1976) is an American technology executive and entrepreneur who co-founded two major technology companies: [[Twitter]], the social media platform that reshaped global communication, and [[Block, Inc.]] (formerly Square, Inc.), the financial services and digital payments company. Dorsey served as CEO of Twitter during two separate tenures—first from 2007 to 2008 and again from 2015 to 2021—while simultaneously guiding the growth of Square from a small mobile payment startup into a publicly traded financial technology firm.<ref>{{cite news |last= |first= |date=2015-10-14 |title=Square Files for IPO as CEO Dorsey Juggles Twitter Revamp |url=https://www.bloomberg.com/news/articles/2015-10-14/square-files-for-ipo-as-ceo-dorsey-juggles-twitter-revamp |work=Bloomberg |access-date=2026-02-23}}</ref> Born and raised in St. Louis, Missouri, Dorsey developed an early interest in dispatch routing and urban infrastructure, interests that would later inform his vision for both real-time public messaging and streamlined commerce.

'''Jack Patrick Dorsey''' (born November 19, 1976) is an American technology executive and entrepreneur who co-founded two of the most consequential technology companies of the early 21st century: [[Twitter]], the social media platform that redefined public discourse and real-time communication, and [[Block, Inc.]] (formerly Square, Inc.), the financial services and digital payments company. Dorsey served as [[chief executive officer]] of Twitter from 2007 to 2008 and again from 2015 to 2021, while simultaneously leading Square (later Block) as its principal executive officer and chairman.<ref>{{cite web |title=About Square |url=https://squareup.com/about#board |publisher=Square |access-date=2026-02-23}}</ref> He is also the founder of [[Bluesky]], a decentralized social media protocol and application.<ref>{{cite web |title=Bluesky {{!}} History, Social Media, Jack Dorsey, & Features |url=https://www.britannica.com/money/Bluesky |publisher=Britannica Money |access-date=2026-02-23}}</ref> Born and raised in St. Louis, Missouri, Dorsey displayed an early interest in the intersection of software and urban infrastructure, interests that would inform both of his major ventures. His career trajectory—from a college dropout tinkering with dispatch routing software to the head of two publicly traded companies—has made him one of the most prominent figures in American technology and finance. In recent years, Dorsey has become a vocal advocate for [[Bitcoin]] and decentralized technologies, guiding Block's strategic direction toward cryptocurrency integration and open-source protocols.


== Early Life ==
== Early Life ==


Jack Patrick Dorsey was born on November 19, 1976, in [[St. Louis, Missouri]]. Growing up in the St. Louis metropolitan area, Dorsey developed a fascination with cities, maps, and the logistics of urban infrastructure from a young age. He was particularly drawn to the workings of dispatch routing—the systems used by emergency services, taxi companies, and courier services to coordinate the real-time movement of vehicles and personnel across a city. This childhood interest in how information moves through urban networks would prove foundational to his later work in technology.
Jack Patrick Dorsey was born on November 19, 1976, in [[St. Louis, Missouri]]. From a young age, Dorsey exhibited a fascination with cities, maps, and the movement of vehicles through urban environments. This interest led him to explore dispatch routing software and the logistics of real-time communication, subjects that would prove foundational to his later entrepreneurial pursuits.


As a teenager, Dorsey began programming and developed software related to dispatch logistics. His early programming work focused on creating systems that could track the real-time positions and activities of dispatch vehicles, a concept that bore a conceptual resemblance to the real-time status updates that would later become the core feature of Twitter. Dorsey's interest in brevity and real-time communication was also influenced by his fascination with the concise, utilitarian nature of dispatch communications, where operators conveyed essential information in the fewest possible words.
Growing up in St. Louis, Dorsey was drawn to computers and programming during his adolescence. He became interested in the technical systems underlying emergency dispatch services, and by the time he was a teenager, he had begun writing dispatch software. His early work in this area attracted attention in the nascent open-source software community. Dorsey's curiosity about how cities functioned—the patterns of taxis, emergency vehicles, and couriers—would later converge with his interest in short-form, real-time messaging to produce the concept behind Twitter.<ref>{{cite web |last= |first= |title=Jack Dorsey: The Man With Two Brains |url=http://fortune.com/2011/06/02/jack-dorsey-the-man-with-two-brains/ |work=Fortune |date=2011-06-02 |access-date=2026-02-23}}</ref>


Dorsey attended the [[University of Missouri–Rolla]] (now Missouri University of Science and Technology) before transferring to [[New York University]]. While living in New York City, he continued developing his ideas about real-time status updates and urban technology. It was during this period that Dorsey began formulating the concept that would eventually become Twitter—a platform where individuals could broadcast short status messages to a network of followers, much as a dispatch system broadcasts the status of vehicles to a central coordinator.
Dorsey's background in St. Louis, a city with a complex economic and social landscape, also influenced his later interest in financial technology and enabling small businesses to accept electronic payments—a motivation that would drive the creation of Square.
 
== Education ==
 
Dorsey attended the [[Missouri University of Science and Technology]] (then known as the University of Missouri–Rolla) before transferring to [[New York University]]. He did not complete a degree at either institution, opting instead to pursue his technology interests in the professional world. While in New York, Dorsey continued to develop dispatch-related software and became immersed in the city's technology scene, which would later inspire both his aspiration to play a public role in urban life and his work on real-time communication platforms.<ref>{{cite news |title=Jack Dorsey on his desire to be Mayor of New York City, Steve Jobs, and being a bachelor |url=http://thelead.blogs.cnn.com/2013/03/21/jack-dorsey-on-his-desire-to-be-mayor-of-new-york-city-steve-jobs-and-being-a-bachelor/ |work=CNN |date=2013-03-21 |access-date=2026-02-23}}</ref>

Dorsey co-founded Twitter in 2006, along with [[Biz Stone]], [[Evan Williams (Internet entrepreneur)|Evan Williams]], and [[Noah Glass]]. The platform was born out of a brainstorming session at [[Odeo]], a podcasting company where Dorsey was working at the time. Dorsey's original concept—inspired by his long-standing interest in dispatch systems and real-time status updates—proposed a service that would allow users to send short text-based messages to a group, sharing what they were doing at any given moment. The name "Twitter" was chosen to evoke the image of a short burst of inconsequential information, similar to the chirps of birds.
Dorsey co-founded Twitter in 2006 alongside [[Evan Williams (Internet entrepreneur)|Evan Williams]], [[Biz Stone]], and [[Noah Glass]]. The platform, which allowed users to post short messages of 140 characters (later expanded to 280), grew rapidly and became a central tool for public communication, news dissemination, and political discourse around the world. Dorsey is credited with proposing the original concept for the service, drawing on his longstanding interest in status updates and real-time dispatch communication.


Twitter launched publicly in July 2006 and quickly gained traction among early technology adopters. Dorsey served as the company's first chief executive officer. Under his initial leadership, the platform grew from a niche service popular among technology enthusiasts into a broader social media platform. However, Dorsey's first tenure as CEO was relatively brief. In 2008, he was moved from the CEO role to the position of chairman of the board, a transition that was reported to have resulted from concerns among the company's board of directors about operational and managerial challenges during a period of rapid growth.<ref>{{cite news |last= |first= |date=2008-10-21 |title=Twitter's Growing Pains |url=https://www.nytimes.com/2008/10/21/technology/start-ups/21twitter.html |work=The New York Times |access-date=2026-02-23}}</ref><ref>{{cite web |title=Twitter CEO Jack Dorsey |url=http://www.informationweek.com/blog/main/archives/2008/06/twitter_ceo_jac_2.html |publisher=InformationWeek |date=2008-06 |access-date=2026-02-23}}</ref><ref>{{cite web |title=Twitter CEO Dorsey Steps Aside |url=http://news.cnet.com/8301-13577_3-10068368-36.html |publisher=CNET |date=2008 |access-date=2026-02-23}}</ref>
Dorsey served as CEO of Twitter from 2007 to 2008. During this initial period, the company was still in its early stages, and Dorsey focused on product development and user growth. However, in 2008, Dorsey was moved from the CEO role to chairman of the board, amid reports of internal disagreements about the company's direction and operational management.<ref>{{cite news |title=Twitter CEO Jack Dorsey |url=http://www.informationweek.com/blog/main/archives/2008/06/twitter_ceo_jac_2.html |work=InformationWeek |date=2008-06-01 |access-date=2026-02-23}}</ref><ref>{{cite news |title=Why Twitter's C.E.O.

Dorsey returned to the role of CEO at Twitter in 2015, taking on the unusual challenge of simultaneously running two publicly traded companies—Twitter and Square.<ref>{{cite news |last= |first= |date=2015-10-14 |title=Square Files for IPO as CEO Dorsey Juggles Twitter Revamp |url=https://www.bloomberg.com/news/articles/2015-10-14/square-files-for-ipo-as-ceo-dorsey-juggles-twitter-revamp |work=Bloomberg |access-date=2026-02-23}}</ref> During this second tenure, Dorsey oversaw efforts to address the platform's challenges with user growth, content moderation, and revenue generation. His dual CEO role attracted significant scrutiny from investors and media commentators, who questioned whether one individual could effectively lead two major public companies at the same time.<ref>{{cite news |last= |first= |date=2011-06-02 |title=Jack Dorsey: The Man with Two Brains |url=http://fortune.com/2011/06/02/jack-dorsey-the-man-with-two-brains/ |work=Fortune |access-date=2026-02-23}}</ref>
In 2015, Dorsey returned as CEO of Twitter, succeeding interim CEO [[Dick Costolo]]. His second tenure was marked by efforts to address long-standing challenges including user growth stagnation, content moderation policies, and the platform's financial performance. Dorsey held the CEO position at Twitter concurrently with his role at Square, a dual arrangement that attracted both praise for his entrepreneurial capacity and criticism from investors and commentators who questioned whether one individual could effectively lead two publicly traded companies simultaneously.<ref>{{cite news |title=Square Files for IPO as CEO Dorsey Juggles Twitter Revamp |url=https://www.bloomberg.com/news/articles/2015-10-14/square-files-for-ipo-as-ceo-dorsey-juggles-twitter-revamp |work=Bloomberg News |date=2015-10-14 |access-date=2026-02-23}}</ref>


Dorsey stepped down as CEO of Twitter in November 2021, handing the role to [[Parag Agrawal]]. The company was subsequently acquired by [[Elon Musk]] in October 2022.

In addition to his work at Twitter, Dorsey initiated the development of Bluesky, a project aimed at creating a decentralized protocol for social media. Bluesky was originally conceived in 2019 as an internal initiative at Twitter, with the goal of developing an open and decentralized standard for social networking that could potentially serve as the underlying architecture for Twitter and other platforms. The project was spun off as an independent entity, Bluesky Social PBC (Public Benefit Corporation).<ref>{{cite web |title=Bluesky {{!}} History, Social Media, Jack Dorsey, & Features |url=https://www.britannica.com/money/Bluesky |publisher=Britannica Money |date= |access-date=2026-02-23}}</ref>
In addition to his work at Twitter, Dorsey founded [[Bluesky]], an initiative to develop a decentralized social media protocol. The project, which began while Dorsey was still at Twitter, aimed to create an open standard for social networking that would not be controlled by any single corporation. Bluesky launched as an independent social media application, allowing users to post short messages of up to 300 characters in a format similar to Twitter's microblogging model.<ref>{{cite web |title=Bluesky {{!}} History, Social Media, Jack Dorsey, & Features |url=https://www.britannica.com/money/Bluesky |publisher=Britannica Money |access-date=2026-02-23}}</ref> The project reflected Dorsey's growing interest in decentralization and open-source protocol development, themes that also informed his work at Block.
 
Bluesky developed the AT Protocol (Authenticated Transfer Protocol), a federated social networking protocol designed to give users more control over their data and online identity. The Bluesky social media application, which allows users to post short messages of up to 300 characters, launched as a public platform and has attracted millions of users.<ref>{{cite web |title=Bluesky {{!}} History, Social Media, Jack Dorsey, & Features |url=https://www.britannica.com/money/Bluesky |publisher=Britannica Money |date= |access-date=2026-02-23}}</ref> While Dorsey played a foundational role in the creation of Bluesky, the platform has since operated independently.

==== Founding and Early Growth ====
Dorsey co-founded Square, Inc. in 2009, alongside [[Jim McKelvey]]. The company was conceived as a way to enable small businesses and individual merchants to accept credit card payments using a small card reader attached to a smartphone or tablet. The idea reportedly originated after McKelvey was unable to complete a sale of his glass artwork because he could not accept credit cards. Square's solution addressed a significant gap in the payments market, particularly for small merchants and mobile vendors who had previously been excluded from electronic payment processing.


Following his departure from the CEO role at Twitter in 2008, Dorsey turned his attention to a new venture in the financial technology space. He co-founded Square, Inc. in 2009 with [[Jim McKelvey]]. The company's initial product was a small, square-shaped card reader that could be plugged into the headphone jack of a smartphone, enabling small businesses, independent merchants, and individuals to accept credit card payments without the need for a traditional point-of-sale terminal. The concept addressed a significant gap in the payments market: millions of small businesses and sole proprietors were unable to accept card payments due to the cost and complexity of conventional merchant account systems.
Square's early headquarters were located in San Francisco, California. The company initially operated out of space in the city's historic [[Chronicle Building]] before opening new headquarters in 2013.<ref>{{cite web |title=Square Opens New Headquarters |url=https://squareup.com/news/releases/2013/square-opens-new-headquarters |publisher=Square |date=2013 |access-date=2026-02-23}}</ref><ref>{{cite web |title=CHD Office Space: Square, San Francisco's Chronicle Building |url=http://www.californiahomedesign.com/blog/2011/06/30/chd-office-space-square-san-franciscos-chronicle-building |publisher=California Home + Design |date=2011-06-30 |access-date=2026-02-23}}</ref>


Square's headquarters were initially located in San Francisco. The company moved its offices to the historic Chronicle Building in San Francisco's South of Market neighborhood.<ref>{{cite web |title=CHD Office Space: Square, San Francisco's Chronicle Building |url=http://www.californiahomedesign.com/blog/2011/06/30/chd-office-space-square-san-franciscos-chronicle-building |publisher=California Home Design |date=2011-06-30 |access-date=2026-02-23}}</ref> In 2013, Square opened new headquarters, further establishing its presence in the city's technology ecosystem.<ref>{{cite web |title=Square Opens New Headquarters |url=https://web.archive.org/web/20140413142657/https://squareup.com/news/releases/2013/square-opens-new-headquarters |publisher=Square |date=2013 |access-date=2026-02-23}}</ref>
The company grew rapidly, expanding from its flagship card reader product into a broader ecosystem of financial services, including point-of-sale systems, small business lending, payroll services, and peer-to-peer payment application [[Cash App]]. By 2012, Square was ranked among the top digital companies by ''[[Business Insider]]''.<ref>{{cite web |title=2012 Digital 100 |url=http://www.businessinsider.com/2012-digital-100#7-square-32-billion-7 |publisher=Business Insider |access-date=2026-02-23}}</ref>


The company grew rapidly. By 2012, ''Business Insider'' ranked Square among its "Digital 100" list of the most valuable private technology companies, valuing the company at $3.2 billion.<ref>{{cite web |title=2012 Digital 100 |url=http://www.businessinsider.com/2012-digital-100#7-square-32-billion-7 |publisher=Business Insider |date=2012 |access-date=2026-02-23}}</ref> Square expanded its product offerings beyond the original card reader to include a suite of business tools, including point-of-sale software, business analytics, payroll services, and lending products aimed at small and medium-sized businesses.
Square filed for its [[initial public offering]] (IPO) in October 2015, during the same period that Dorsey was resuming the CEO role at Twitter. The IPO filing drew attention to Dorsey's dual leadership positions and to questions about Square's ownership structure and valuation.<ref>{{cite news |title=Square Files for IPO as CEO Dorsey Juggles Twitter Revamp |url=https://www.bloomberg.com/news/articles/2015-10-14/square-files-for-ipo-as-ceo-dorsey-juggles-twitter-revamp |work=Bloomberg News |date=2015-10-14 |access-date=2026-02-23}}</ref><ref>{{cite news |title=Square Ownership: Dorsey IPO |url=http://fortune.com/2015/10/14/square-ownership-dorsey-ipo/ |work=Fortune |date=2015-10-14 |access-date=2026-02-23}}</ref>


==== IPO and Expansion ====
In late 2021, Square, Inc. was renamed '''Block, Inc.''', reflecting the company's broadened focus beyond payment processing to include blockchain technology, [[Bitcoin]] mining, and decentralized financial services. Dorsey, who had become an outspoken proponent of Bitcoin, positioned Block as a company at the intersection of traditional financial services and cryptocurrency. The company trades on the [[New York Stock Exchange]] under the ticker symbol XYZ.<ref>{{cite news |title=Jack Dorsey's Block Gears For Q4 Earnings |url=https://www.benzinga.com/crypto/cryptocurrency/26/02/50772911/jack-dorseys-block-gears-for-q4-earnings-analyst-expectations-key-technical-signals-price-targets-and-all-you-need-to-know |work=Benzinga |date=2026-02-23 |access-date=2026-02-23}}</ref>


Square filed for its initial public offering (IPO) in October 2015, at a time when Dorsey was juggling his dual role as CEO of both Square and Twitter.<ref>{{cite news |last= |first= |date=2015-10-14 |title=Square Files for IPO as CEO Dorsey Juggles Twitter Revamp |url=https://www.bloomberg.com/news/articles/2015-10-14/square-files-for-ipo-as-ceo-dorsey-juggles-twitter-revamp |work=Bloomberg |access-date=2026-02-23}}</ref> At the time of its IPO filing, Dorsey held a significant ownership stake in the company.<ref>{{cite news |last= |first= |date=2015-10-14 |title=Square Ownership Dorsey IPO |url=http://fortune.com/2015/10/14/square-ownership-dorsey-ipo/ |work=Fortune |access-date=2026-02-23}}</ref> The company went public on the [[New York Stock Exchange]] and subsequently grew into a major financial technology platform.
Under Dorsey's leadership, Block has pursued initiatives in Bitcoin adoption, including enabling small businesses to accept Bitcoin payments. In February 2026, reports indicated that Block was facilitating Bitcoin acceptance for small businesses with zero transaction fees, a move aimed at expanding cryptocurrency use in everyday commerce.<ref>{{cite web |title=Jack Dorsey's Bitcoin Revolution: Small Businesses Now Accept BTC With ZERO Fees |url=https://www.binance.com/en-NG/square/post/294764551085649 |publisher=Binance |date=2026-02-23 |access-date=2026-02-23}}</ref>


Over the following years, Square expanded into consumer-facing financial services through its Cash App, a peer-to-peer payment application that grew to rival established services in the digital payments space. Cash App became a significant revenue driver for the company, offering features including direct deposit, stock trading, and Bitcoin purchasing.
Dorsey has also faced scrutiny over his interest in Bitcoin. During Block's Investor Day in November 2025, a question was raised about whether Dorsey could be [[Satoshi Nakamoto]], the pseudonymous creator of Bitcoin—a claim that Dorsey has not confirmed and that remains the subject of speculation rather than established fact.<ref>{{cite news |title=Jack Dorsey Sparks Debate: Could He Be the Elusive Satoshi Nakamoto? |url=https://www.investopedia.com/jack-dorsey-sparks-debate-11880164 |work=Investopedia |date=2026-01 |access-date=2026-02-23}}</ref>


==== Rebranding to Block and Bitcoin Focus ====
=== Workforce Reductions and AI Strategy at Block (2026) ===


In December 2021, Square, Inc. was renamed Block, Inc., reflecting the company's broadened strategic focus beyond its original square card reader. The name "Block" referenced multiple concepts central to the company's evolving identity, including building blocks, neighborhood blocks, and blockchain technology. Dorsey continued as the company's principal executive officer and chairman of the board.<ref>{{cite web |title=About Square |url=https://squareup.com/about#board |publisher=Square |date= |access-date=2026-02-23}}</ref>
In early 2026, Block undertook significant workforce reductions. In February, reports indicated that the company was cutting up to 10% of its staff as part of annual performance reviews.<ref>{{cite news |last= |first= |date=2026-02-07 |title=Dorsey's Block cutting up to 10% of staff, Bloomberg News reports |url=https://www.reuters.com/business/dorseys-block-cutting-up-10-staff-bloomberg-news-reports-2026-02-07/ |work=Reuters |access-date=2026-02-23}}</ref> The layoffs affected hundreds of employees and were followed by what reporting described as "rolling layoffs" that continued over subsequent weeks.<ref>{{cite news |title=Inside the Rolling Layoffs at Jack Dorsey's Block |url=https://www.wired.com/story/inside-rolling-layoffs-jack-dorsey-block/ |work=WIRED |date=2026-02-19 |access-date=2026-02-23}}</ref>


Under Dorsey's leadership, Block placed increasing emphasis on [[Bitcoin]] and cryptocurrency. The company invested corporate funds in Bitcoin and developed products and services designed to facilitate Bitcoin transactions for both merchants and consumers. In 2026, Block announced features enabling small businesses to accept Bitcoin payments with zero transaction fees, a move intended to accelerate cryptocurrency adoption among mainstream merchants.<ref>{{cite web |title=Jack Dorsey's Bitcoin Revolution Small Businesses Now Accept BTC With ZERO Fees |url=https://www.binance.com/en-NG/square/post/294764551085649 |publisher=Binance |date=2026-02-23 |access-date=2026-02-23}}</ref>
Simultaneously, Dorsey pushed an aggressive mandate for the adoption of [[artificial intelligence]] tools within the company. Employees were reportedly required to integrate AI into their workflows, a directive that generated internal dissatisfaction. Reports from ''Inc.'' and ''Futurism'' described employee backlash in response to the combination of mass layoffs and AI mandates, with some workers expressing concern about job security and the pace of organizational change.<ref>{{cite news |title=Jack Dorsey Faces Employee Backlash After Mass Layoffs and AI Mandates at Block |url=https://www.inc.com/kevin-haynes/jack-dorsey-faces-employee-backlash-after-mass-layoffs-and-ai-mandates-at-block-inc/91306381 |work=Inc. |date=2026-02-21 |access-date=2026-02-23}}</ref><ref>{{cite news |title=Jack Dorsey's New Company Falling Apart as It Forces Employees to Use AI |url=https://futurism.com/artificial-intelligence/jack-dorsey-block-falling-apart-ai |work=Futurism |date=2026-02-20 |access-date=2026-02-23}}</ref> The situation drew media attention and raised questions about Dorsey's management approach and the future direction of Block.


Dorsey's personal advocacy for Bitcoin has been a defining feature of his public profile in recent years. At Block's Investor Day in November 2025, the subject of whether Dorsey could be [[Satoshi Nakamoto]], the pseudonymous creator of Bitcoin, was raised—a question that Dorsey has not claimed but that has generated public speculation and debate.<ref>{{cite web |title=Jack Dorsey Sparks Debate: Could He Be the Elusive Satoshi Nakamoto? |url=https://www.investopedia.com/jack-dorsey-sparks-debate-11880164 |publisher=Investopedia |date=2026-01 |access-date=2026-02-23}}</ref>
=== Board Memberships ===


==== 2026 Layoffs and AI Strategy ====
In December 2013, Dorsey was appointed to the board of directors of [[The Walt Disney Company]], one of the youngest directors in Disney's history at the time.<ref>{{cite news |title=Jack Dorsey Joins Disney |url=https://techcrunch.com/2013/12/23/jack-dorsey-joins-disney/?ncid=tcdaily |work=TechCrunch |date=2013-12-23 |access-date=2026-02-23}}</ref> He served on the Disney board until January 2018, when he departed along with [[Sheryl Sandberg]] of Facebook.<ref>{{cite news |title=Facebook's Sandberg, Twitter's Dorsey to Depart Disney Board |url=https://www.bloomberg.com/news/articles/2018-01-13/facebook-s-sandberg-twitter-s-dorsey-to-depart-disney-board |work=Bloomberg News |date=2018-01-13 |access-date=2026-02-23}}</ref>


In early 2026, Block underwent significant organizational changes under Dorsey's direction. In February 2026, the company laid off hundreds of employees as part of a broader restructuring that reportedly included cutting up to 10% of its workforce during annual performance reviews.<ref>{{cite news |last= |first= |date=2026-02-07 |title=Dorsey's Block cutting up to 10% of staff, Bloomberg News reports |url=https://www.reuters.com/business/dorseys-block-cutting-up-10-staff-bloomberg-news-reports-2026-02-07/ |work=Reuters |access-date=2026-02-23}}</ref> The layoffs were accompanied by an aggressive push to integrate artificial intelligence throughout Block's operations, with Dorsey mandating that employees adopt AI tools as part of their daily workflows.<ref>{{cite news |last=Haynes |first=Kevin |date=2026-02-21 |title=Jack Dorsey Faces Employee Backlash After Mass Layoffs and AI Mandates at Block |url=https://www.inc.com/kevin-haynes/jack-dorsey-faces-employee-backlash-after-mass-layoffs-and-ai-mandates-at-block-inc/91306381 |work=Inc. |access-date=2026-02-23}}</ref>

Dorsey's dual role as CEO of two publicly traded companies drew comparisons to other technology leaders who have managed multiple large-scale ventures simultaneously. His leadership of Twitter during its cultural and political ascendance, combined with his role in building Square into a major financial services company, established him as one of the more prominent figures in Silicon Valley during the 2010s.

Jack Dorsey's influence on the technology industry rests on two distinct but related contributions: the creation of a real-time public messaging platform that altered the dynamics of global communication, media, and politics, and the development of a financial technology platform that expanded access to digital payments for small businesses and independent merchants.
Jack Dorsey's impact on the technology industry rests on two central contributions: the creation of a real-time, public, short-form messaging platform in Twitter, and the democratization of electronic payment acceptance through Square. Twitter, for all the controversies that later surrounded it, fundamentally altered how news was disseminated, how public figures communicated with audiences, and how protest movements organized. The platform's role in events ranging from the [[Arab Spring]] to U.S. presidential elections cemented its place in the history of digital communication.


Twitter, which Dorsey co-founded in 2006, became a central platform for political discourse, breaking news, and cultural conversation. The service's format of short, public messages—originally limited to 140 characters—created a new paradigm for how individuals, organizations, and governments communicated with the public. During Dorsey's tenures as CEO, Twitter grew from a startup to a publicly traded company with global reach, though the platform also faced persistent challenges related to misinformation, harassment, and content moderation.
Square, and its successor Block, addressed a practical economic problem—the exclusion of small merchants from electronic payments—and built a financial services ecosystem that expanded to include lending, payroll, and peer-to-peer transfers through Cash App. The company's pivot toward Bitcoin and blockchain under Dorsey's leadership represented a bet on decentralized finance that continued to shape its trajectory into 2026.


Square, later renamed Block, addressed a fundamental problem in the payments industry by making it simple and affordable for small merchants to accept credit card payments. The company's original card reader, which plugged into a smartphone, became a ubiquitous tool at farmers' markets, food trucks, and small retail shops. The subsequent development of Cash App expanded Block's reach into consumer financial services, including peer-to-peer payments and cryptocurrency transactions.
Dorsey's founding of Bluesky reflected a philosophical evolution in his thinking about social media, moving from the centralized model of Twitter toward a decentralized protocol that aimed to give users more control over their data and online interactions.<ref>{{cite web |title=Bluesky {{!}} History, Social Media, Jack Dorsey, & Features |url=https://www.britannica.com/money/Bluesky |publisher=Britannica Money |access-date=2026-02-23}}</ref>


Dorsey's more recent focus on Bitcoin and decentralized technology has positioned him as a prominent advocate for cryptocurrency adoption in mainstream commerce. His decision to rename Square to Block and to orient the company's strategy around Bitcoin and blockchain technology signals a long-term commitment to decentralized financial infrastructure. The 2026 introduction of zero-fee Bitcoin acceptance for small businesses through Block represents a continuation of Dorsey's original mission with Square: simplifying financial transactions for small-scale merchants.
His career has also illustrated tensions inherent in technology leadership: the challenges of managing dual CEO roles, the friction between corporate restructuring and employee morale, and the difficulty of balancing innovation-driven mandates—such as the aggressive adoption of AI at Block—with organizational stability.<ref>{{cite news |title=Inside the Rolling Layoffs at Jack Dorsey's Block |url=https://www.wired.com/story/inside-rolling-layoffs-jack-dorsey-block/ |work=WIRED |date=2026-02-19 |access-date=2026-02-23}}</ref> As of early 2026, Dorsey remained at the helm of Block, navigating a period of significant organizational change while continuing to advocate for Bitcoin adoption and decentralized technologies.
 
The organizational challenges at Block in early 2026—including mass layoffs and the controversial mandate to integrate AI into employee workflows—illustrate the tensions inherent in rapid corporate transformation. The outcome of these initiatives will likely shape the next phase of Dorsey's legacy as a technology executive.

Website[https://squareup.com/ Official site]

Jack Patrick Dorsey (born November 19, 1976) is an American technology executive and entrepreneur who co-founded two of the most consequential technology companies of the early 21st century: Twitter, the social media platform that redefined public discourse and real-time communication, and Block, Inc. (formerly Square, Inc.), the financial services and digital payments company. Dorsey served as chief executive officer of Twitter from 2007 to 2008 and again from 2015 to 2021, while simultaneously leading Square (later Block) as its principal executive officer and chairman.[1] He is also the founder of Bluesky, a decentralized social media protocol and application.[2] Born and raised in St. Louis, Missouri, Dorsey displayed an early interest in the intersection of software and urban infrastructure, interests that would inform both of his major ventures. His career trajectory—from a college dropout tinkering with dispatch routing software to the head of two publicly traded companies—has made him one of the most prominent figures in American technology and finance. In recent years, Dorsey has become a vocal advocate for Bitcoin and decentralized technologies, guiding Block's strategic direction toward cryptocurrency integration and open-source protocols.

Early Life

Jack Patrick Dorsey was born on November 19, 1976, in St. Louis, Missouri. From a young age, Dorsey exhibited a fascination with cities, maps, and the movement of vehicles through urban environments. This interest led him to explore dispatch routing software and the logistics of real-time communication, subjects that would prove foundational to his later entrepreneurial pursuits.

Growing up in St. Louis, Dorsey was drawn to computers and programming during his adolescence. He became interested in the technical systems underlying emergency dispatch services, and by the time he was a teenager, he had begun writing dispatch software. His early work in this area attracted attention in the nascent open-source software community. Dorsey's curiosity about how cities functioned—the patterns of taxis, emergency vehicles, and couriers—would later converge with his interest in short-form, real-time messaging to produce the concept behind Twitter.[3]

Dorsey's background in St. Louis, a city with a complex economic and social landscape, also influenced his later interest in financial technology and enabling small businesses to accept electronic payments—a motivation that would drive the creation of Square.

Education

Dorsey attended the Missouri University of Science and Technology (then known as the University of Missouri–Rolla) before transferring to New York University. He did not complete a degree at either institution, opting instead to pursue his technology interests in the professional world. While in New York, Dorsey continued to develop dispatch-related software and became immersed in the city's technology scene, which would later inspire both his aspiration to play a public role in urban life and his work on real-time communication platforms.[4]

Career

Twitter

Dorsey co-founded Twitter in 2006 alongside Evan Williams, Biz Stone, and Noah Glass. The platform, which allowed users to post short messages of 140 characters (later expanded to 280), grew rapidly and became a central tool for public communication, news dissemination, and political discourse around the world. Dorsey is credited with proposing the original concept for the service, drawing on his longstanding interest in status updates and real-time dispatch communication.

Dorsey served as CEO of Twitter from 2007 to 2008. During this initial period, the company was still in its early stages, and Dorsey focused on product development and user growth. However, in 2008, Dorsey was moved from the CEO role to chairman of the board, amid reports of internal disagreements about the company's direction and operational management.[5][6] The leadership transition was later described as a period of significant internal tension at the company.[7]

In 2015, Dorsey returned as CEO of Twitter, succeeding interim CEO Dick Costolo. His second tenure was marked by efforts to address long-standing challenges including user growth stagnation, content moderation policies, and the platform's financial performance. Dorsey held the CEO position at Twitter concurrently with his role at Square, a dual arrangement that attracted both praise for his entrepreneurial capacity and criticism from investors and commentators who questioned whether one individual could effectively lead two publicly traded companies simultaneously.[8]

Dorsey stepped down as CEO of Twitter in November 2021, handing the role to Parag Agrawal. Twitter was subsequently acquired by Elon Musk in 2022.

Bluesky

In addition to his work at Twitter, Dorsey founded Bluesky, an initiative to develop a decentralized social media protocol. The project, which began while Dorsey was still at Twitter, aimed to create an open standard for social networking that would not be controlled by any single corporation. Bluesky launched as an independent social media application, allowing users to post short messages of up to 300 characters in a format similar to Twitter's microblogging model.[9] The project reflected Dorsey's growing interest in decentralization and open-source protocol development, themes that also informed his work at Block.

Square and Block, Inc.

Dorsey co-founded Square, Inc. in 2009, alongside Jim McKelvey. The company was conceived as a way to enable small businesses and individual merchants to accept credit card payments using a small card reader attached to a smartphone or tablet. The idea reportedly originated after McKelvey was unable to complete a sale of his glass artwork because he could not accept credit cards. Square's solution addressed a significant gap in the payments market, particularly for small merchants and mobile vendors who had previously been excluded from electronic payment processing.

Square's early headquarters were located in San Francisco, California. The company initially operated out of space in the city's historic Chronicle Building before opening new headquarters in 2013.[10][11]

The company grew rapidly, expanding from its flagship card reader product into a broader ecosystem of financial services, including point-of-sale systems, small business lending, payroll services, and peer-to-peer payment application Cash App. By 2012, Square was ranked among the top digital companies by Business Insider.[12]

Square filed for its initial public offering (IPO) in October 2015, during the same period that Dorsey was resuming the CEO role at Twitter. The IPO filing drew attention to Dorsey's dual leadership positions and to questions about Square's ownership structure and valuation.[13][14]

In late 2021, Square, Inc. was renamed Block, Inc., reflecting the company's broadened focus beyond payment processing to include blockchain technology, Bitcoin mining, and decentralized financial services. Dorsey, who had become an outspoken proponent of Bitcoin, positioned Block as a company at the intersection of traditional financial services and cryptocurrency. The company trades on the New York Stock Exchange under the ticker symbol XYZ.[15]

Under Dorsey's leadership, Block has pursued initiatives in Bitcoin adoption, including enabling small businesses to accept Bitcoin payments. In February 2026, reports indicated that Block was facilitating Bitcoin acceptance for small businesses with zero transaction fees, a move aimed at expanding cryptocurrency use in everyday commerce.[16]

Dorsey has also faced scrutiny over his interest in Bitcoin. During Block's Investor Day in November 2025, a question was raised about whether Dorsey could be Satoshi Nakamoto, the pseudonymous creator of Bitcoin—a claim that Dorsey has not confirmed and that remains the subject of speculation rather than established fact.[17]

Workforce Reductions and AI Strategy at Block (2026)

In early 2026, Block undertook significant workforce reductions. In February, reports indicated that the company was cutting up to 10% of its staff as part of annual performance reviews.[18] The layoffs affected hundreds of employees and were followed by what reporting described as "rolling layoffs" that continued over subsequent weeks.[19]

Simultaneously, Dorsey pushed an aggressive mandate for the adoption of artificial intelligence tools within the company. Employees were reportedly required to integrate AI into their workflows, a directive that generated internal dissatisfaction. Reports from Inc. and Futurism described employee backlash in response to the combination of mass layoffs and AI mandates, with some workers expressing concern about job security and the pace of organizational change.[20][21] The situation drew media attention and raised questions about Dorsey's management approach and the future direction of Block.

Board Memberships

In December 2013, Dorsey was appointed to the board of directors of The Walt Disney Company, one of the youngest directors in Disney's history at the time.[22] He served on the Disney board until January 2018, when he departed along with Sheryl Sandberg of Facebook.[23]

Dorsey has also served on the board of the Berggruen Institute's governance center, reflecting his interest in issues related to governance, technology, and public policy.

Personal Life

Dorsey has spoken publicly about his interest in becoming involved in public life beyond technology. In a 2013 interview with CNN, he discussed his desire to potentially pursue a role such as Mayor of New York City, an ambition that reflected his longstanding fascination with urban systems and civic governance.[24]

Dorsey is known for his interest in wellness practices, including meditation and fasting, which have been the subject of media coverage. He has cited Steve Jobs as an influence on his approach to product design and business leadership.[25]

In 2019, Dorsey was among the supporters of #TeamTrees, a charitable campaign organized by YouTube creator MrBeast that aimed to plant 20 million trees. The initiative raised significant funds from technology industry figures and the general public.[26]

Dorsey has been a prominent advocate for Bitcoin and has stated that he believes it has the potential to become the internet's native currency. This conviction has shaped his leadership at Block and his public commentary on the future of finance and technology.

Recognition

Dorsey has received recognition from multiple business and technology publications for his entrepreneurial work. In 2011, the San Francisco Business Times named him Executive of the Year, citing his dual leadership of Twitter and Square and his impact on the San Francisco technology ecosystem.[27]

That same year, the New York City Mayor's office acknowledged Dorsey's contributions to the technology sector in a public statement.[28]

Fortune profiled Dorsey in 2011 under the headline "The Man With Two Brains," highlighting the unusual nature of his simultaneous leadership of two major technology companies and his ability to conceptualize products across the distinct domains of social media and financial technology.[29]

Dorsey's appointment to the Disney board in 2013 was itself considered a mark of his standing in the business world, given that Disney's board has historically included prominent business leaders and public figures.[30]

In the fashion and design world, Women's Wear Daily profiled Dorsey's work at Square, noting his focus on simplifying commerce and his design-centric approach to financial technology products.[31]
