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.
Jack Dorsey is the co-founder and CEO of Block Inc, previously known as Square Inc, which he founded alongside Jim McKelvey in 2009 following a period of reflection after his departure from Twitter's CEO role. Dorsey's vision for Square was rooted in his belief that financial infrastructure should be accessible to everyone, regardless of income level or geographic location. Over fifteen years, he transformed a simple card reader into a multi-platform financial ecosystem encompassing merchant services, consumer banking, buy-now-pay-later, and Bitcoin infrastructure. Dorsey's leadership style is unconventional by Silicon Valley standards — he is known for extended meditation retreats, minimalist personal habits, and a philosophical commitment to decentralization that has shaped Block's product roadmap in ways that often confound traditional fintech investors. His evangelical commitment to Bitcoin as a transformative financial technology is a defining feature of Block's corporate identity and long-term strategy.
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 highly 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 12,000 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 a 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, a 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.
Jack Dorsey co-founded Square in 2009 with Jim McKelvey after McKelvey, an artisan glassblower, lost a $2,000 sale because he couldn't accept a credit card payment for a glass faucet, demonstrating that small merchants without merchant accounts were excluded from card payments. Square's first product was the iconic white square card reader plugging into smartphone audio jacks, allowing any merchant with an iPhone to accept Visa/Mastercard with no upfront cost or merchant account application — a radical simplification of payments infrastructure. The reader launched in 2010 at no upfront cost (revenue from 2.75% per swipe), and by 2012 Square was processing $10 billion in annual payments from hundreds of thousands of small merchants previously excluded from credit card networks.
Square renamed to Block Inc in December 2021 to reflect the company's expansion beyond Square merchant services into multiple businesses including Cash App, Afterpay (buy-now-pay-later), Tidal music, and crypto initiatives, with 'Block' chosen to evoke neighbourhoods (Square's heritage), building blocks (the company's modular ecosystems), and blockchain (CEO Jack Dorsey's bitcoin enthusiasm). The Square brand remained for the merchant services subsidiary, but Block elevated the holding company structure with separate divisions reporting to corporate. The renaming followed Dorsey's resignation as Twitter CEO in late 2021, allowing him to focus exclusively on Block and signal the company's strategic ambition beyond payment processing into a broader financial services and consumer technology platform.
Cash App, launched in 2013 as a peer-to-peer payment service to compete with Venmo, grew to 56+ million monthly active users by 2024 and became Block's most valuable business segment, generating $4+ billion in annual revenue through Cash App Card debit card interchange fees, bitcoin trading commissions, instant deposit fees, and Cash App Investing brokerage. The product's viral growth — particularly among young consumers and underbanked demographics — created a financial services platform reaching demographics traditional banks struggle to serve. Cash App's expansion into stock investing (zero commission), bitcoin trading, savings (4%+ APY), and tax filing has positioned Block to compete against traditional banks and brokers, while the cultural cachet from rapper endorsements and meme culture gave Cash App brand strength that conservative financial services competitors cannot replicate.
Block (then renaming from Square) acquired Australian buy-now-pay-later (BNPL) pioneer Afterpay in January 2022 for $29 billion in all-stock — its largest acquisition ever — to integrate BNPL across Square merchant services and Cash App consumer products, betting that pay-in-four installment offerings would become a primary consumer payment method. The deal closed during BNPL's peak hype period when rising interest rates and consumer credit concerns had not yet emerged, and Block paid premium valuations that have since proven dramatically unsupported as Afterpay's growth stalled and credit losses increased. Block recorded $1.5+ billion in Afterpay-related goodwill impairments through 2024, validating critics' concerns that the deal was both poorly timed and structurally challenged as BNPL's economic model required low interest rates to remain profitable.
Square went public on 19 November 2015 on the New York Stock Exchange under the ticker SQ at $9 per share, raising $243 million in a downsized offering that valued the company at about $2.9 billion fully diluted, roughly half of the $6 billion valuation Square had attained in its October 2014 Series E round led by Government of Singapore Investment Corporation, Goldman Sachs and Rizvi Traverse. The IPO triggered a contractual ratchet protection clause that forced Square to issue additional shares to the Series E investors to compensate for the lower price, costing existing holders approximately $93 million of additional dilution. Lead underwriters Goldman Sachs, Morgan Stanley and JPMorgan had originally marketed the deal at $11 to $13 per share in October 2015 before cutting the range as public investors balked at Square's $154 million operating loss on $1.27 billion of 2015 revenue and its single-product reliance on card-reader hardware. The down-round IPO became a widely cited cautionary tale for the late-stage private market, prompting reassessment of so-called unicorn valuations across the 2014 to 2015 vintage. Yet the stock closed its first day at $13.07, up 45%, and crossed $20 by August 2016 once Square Capital lending and Cash App user growth started to reframe the company as a fintech platform rather than a payments hardware business.
