Company History
Founded 2009 in San Francisco, California
The original Square card reader was built around the insight that a credit card's magnetic stripe stores data as audio signals — and that an iPhone's headphone jack could read those signals. Cash App launched as Square Cash in 2013, originally as a simple peer-to-peer payment tool that competed with Venmo and PayPal.
Block (originally Square) was founded in 2009 by Jack Dorsey and Jim McKelvey, born out of a personal frustration with the exclusionary nature of the traditional financial system. Dorsey was already legendary in Silicon Valley as the co-founder and former CEO of Twitter. After being ousted from Twitter in 2008 (he would later return) Dorsey was exploring new ventures. He reconnected with McKelvey, a long-time friend and former boss from St. Louis who was working as a glassblowing artist. The foundational 'aha' moment for the company occurred when McKelvey lost a $2,000 sale on a piece of glass art because he could not accept American Express. At the time, accepting credit cards was a logistical nightmare for small merchants; it required signing complex, multi-year contracts with banks, undergoing extensive credit checks, and purchasing expensive, clunky hardware terminals. The system systematically excluded independent artists, food trucks, and small vendors. Dorsey and McKelvey realized that almost everyone was beginning to carry a supercomputer in their pocket (the iPhone), which could easily function as a point-of-sale terminal. They designed a tiny, elegant, square-shaped piece of white plastic that plugged directly into the iPhone's headphone jack, allowing anyone to swipe a credit card. More importantly, Square handled all the complex banking regulations on the backend, offering merchants a simple, flat-rate fee with zero hidden costs. This hardware and software innovation democratized access to the financial system, instantly transforming millions of small vendors into legitimate businesses and launching one of the most successful fintech companies in history.
Jim McKelvey is the co-founder of Block Inc (formerly Square) whose experience as a glassblower unable to accept a credit card payment directly prompted the company's founding. McKelvey contributed the original problem insight and early technical intuition that led to the Square dongle's design, working with Dorsey and hardware engineer Tristan O'Tier to build the first prototype. After the company's early growth phase, McKelvey transitioned to a board member role, later stepping down from the board entirely. He channeled his entrepreneurial experience into writing 'The Innovation Stack: Building an Unbeatable Business One Crazy Idea at a Time,' published in 2020, which theorizes that true disruption requires solving multiple interconnected problems simultaneously in ways that make simple copying impossible. McKelvey remains a regarded figure in the St. Louis entrepreneurial community and a board member at the Federal Reserve Bank of St. Louis.
Jack Dorsey and Jim McKelvey incorporate Square Inc after McKelvey loses a $2,000 glass artwork sale because he cannot accept an American Express card. The founding team builds the first prototype of the Square audio-jack card reader within weeks.
Square's white card reader debuts publicly and is made available through Apple Stores and Best Buy, using a consumer retail distribution strategy rather than a traditional B2B enterprise sales model. The company begins processing real transactions for merchants.
Visa Inc makes a strategic investment in Square, providing both capital and a powerful signal of credibility to the merchant payments ecosystem. The investment validates Square's position within the existing card network infrastructure.
Square announces a high-profile payment processing partnership with Starbucks covering all 7,000 US locations. Jack Dorsey joins the Starbucks board. The deal proves commercially uneconomical for Square, reportedly generating losses of $80–100 million before its termination in 2015.
Square launches Square Cash, a peer-to-peer money transfer app that allows individuals to send money to one another via email. The product is initially simple and free, laying the foundation for what would become Cash App.
Square goes public on the New York Stock Exchange under the ticker SQ at an initial offering price of $9 per share, valuing the company at approximately $2.9 billion — below its 2014 private valuation of $6 billion. The IPO raises approximately $243 million.
Square rebrands its peer-to-peer payment product as Cash App and begins expanding it beyond P2P transfers to include the Cash App Card (a debit card) and Cash App Investing (commission-free stock trading), transforming it toward a full consumer financial platform.
Square announces the acquisition of Australian buy-now-pay-later pioneer Afterpay for approximately $29 billion in an all-stock deal — the largest fintech acquisition in history at the time. In the same year, Square Financial Services receives its industrial bank charter from Utah regulators, enabling direct balance-sheet lending.
In December 2021, Square Inc officially renames itself Block Inc to reflect its expanded mission beyond merchant payments, encompassing Square, Cash App, Afterpay, TIDAL, and its Bitcoin and blockchain initiatives. The NYSE ticker SQ is retained.
Block completes its acquisition of Afterpay in January 2022, adding the BNPL platform to its ecosystem. The deal closes at a final all-stock value of approximately $29 billion, integrating Afterpay's merchant network and consumer base into Block's infrastructure.
Hindenburg Research publishes a critical short-seller report alleging Cash App user count inflation and fraud vulnerabilities. Block denies the central allegations. Separately, Block announces a significant workforce reduction, cutting from approximately 14,000 to approximately 10,205 employees as part of a cost discipline initiative.
Block reaches a settlement with the CFPB and state regulators over Cash App's fraud dispute practices, agreeing to pay approximately $255 million in consumer redress and $80 million in civil penalties. In the same year, the company reports FY2024 adjusted EBITDA of approximately $1.7 billion, a significant milestone toward sustainable profitability.
Block acquired Afterpay to add a buy-now-pay-later capability to its consumer finance ecosystem, connecting Afterpay's merchant network with Cash App's consumer base to create a closed-loop installment payment network. The acquisition was also intended to accelerate Block's international expansion, particularly in Australia and the United Kingdom, where Afterpay had strong market penetration. Management articulated a vision of Afterpay becoming the preferred checkout option at Square merchants worldwide, funded through Cash App consumer relationships.
Block acquired the tax filing business divested by Credit Karma (which was being acquired by Intuit and required by the DOJ to divest its tax product as an antitrust condition) for approximately $50 million. The acquisition gave Block a ready-made, consumer-tested tax filing platform that could be integrated into Cash App and offered for free to users as an engagement and retention tool. Tax filing represents an once-annual high-intent financial activity that surfaces detailed income and expense data Block could use to inform other product decisions.
Block acquired a majority stake in TIDAL, the music streaming service co-owned by Jay-Z and a group of prominent musicians, for approximately $297 million in early 2021. The acquisition was intended to give Block a foothold in the creator economy and a platform for building direct artist-to-fan financial relationships, including direct payment tools that would allow artists to receive streaming royalties and merchandise revenue more efficiently. Dorsey articulated a vision of TIDAL as a financial infrastructure platform for musicians, not simply a streaming service.
Block acquired Verse, an European peer-to-peer payments app popular in Spain and other European markets, as part of an effort to build an international Cash App presence. Verse had approximately 3 million users and offered a peer-to-peer payment experience analogous to Cash App's core functionality. The acquisition was intended to give Cash App an entry point in European markets where regulatory frameworks for payment services are materially different from the US.
