Block Inc and Carta, Inc. pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between Block Inc and Carta, Inc..

Block Inc business model: Block operates a, dual-engine fintech model. The "Square" division generates reliable revenue by providing payment terminals and SaaS business software to millions of small merchants. The large, explosive growth engine is "Cash App." Originally a simple peer-to-peer payment tool (like Venmo), Cash App morphed into a considerable, lucrative digital bank for the "underbanked," generating revenue through instant transfer fees, debit card interchange fees, and controversial Bitcoin trading margins. Block operates a two-sided financial ecosystem consisting of Square and Cash App. Square serves merchants, generating revenue through payment processing fees, point-of-sale hardware sales, and a lucrative suite of software subscriptions for payroll and inventory management. Cash App serves consumers, driving revenue through instant transfer fees, Bitcoin trading spreads, and interchange fees from the Cash Card. By closing the loop between merchants and consumers, Block seeks to eventually bypass traditional banking networks and lower processing costs. The company targets underbanked populations and small businesses historically ignored by legacy financial institutions. Block heavily invests in decentralized finance protocols (like TBD) and Bitcoin infrastructure, betting that open protocols will eventually serve as the foundation for the next generation of global payments, effectively turning the company into a full-stack financial services provider operating outside the traditional banking rails.

Carta, Inc. business model: Carta operates an exceptionally high-compounding, multi-product software-as-a-service (SaaS) subscription and financial administration business model characterized by software gross margins exceeding 75% and industry-shattering enterprise customer retention. Its commercial revenue engine spans four core pillars: First, annual cap table management SaaS subscriptions priced on stakeholder tiers (ranging from $3,000/year for early-stage startups to over $50,000+/year for late-stage enterprise unicorns). Second, recurring 409A valuation software subscriptions providing continuous IRS-compliant fair market appraisals. Third, venture capital fund administration fees (recurring basis points on committed fund capital plus fixed administrative fees) managing over 7,000 venture funds and SPVs across $130B+ in AUM. Fourth, Carta Total Compensation modular SaaS licenses charging high-growth companies for live compensation market benchmarking data.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of Block Inc stack up against those of Carta, Inc..

Carta, Inc. competitive advantage: Carta's competitive advantage is anchored in four insurmountable legal, technological, and ecosystem moats: First, immense private asset scale: managing over $3.0 trillion in private corporate equity across 40,000+ companies and 2 million equity holders. Second, dual-sided venture network effects: administering 7,000+ venture capital funds with $130B+ in AUM who mandate that their portfolio startups use Carta. Third, institutional legal integration: embedded as the default corporate registry across top global tech law firms (Cooley, Wilson Sonsini, Fenwick & West). Fourth, unshakeable customer trust: demonstrated when CEO Henry Ward decisively shut down the secondary liquidity brokerage in January 2024 within 48 hours to protect client confidentiality.

A closer look at the financial trajectory of Block Inc and Carta, Inc. rounds out the comparison.

Block Inc: Block (formerly Square) is executing a ruthless pivot toward consistent GAAP profitability in 2026. Under CEO Jack Dorsey, the fintech giant generated exactly $22.7 billion in revenue and maintains a $45.1 billion market cap with exactly 12985 employees. The financial narrative is defined by the lucrative success of the Cash App ecosystem, which has effectively cornered the peer-to-peer payments and retail bitcoin trading market in the United States. Cash App's margins heavily subsidize the slower, more mature growth of the traditional Square merchant business and the ongoing integration struggles of the $29 billion Afterpay (Buy Now, Pay Later) acquisition. To appease Wall Street, Dorsey has implemented sweeping layoffs and enforced a hard cap on the company's total headcount.

Carta, Inc.: Carta represents one of the most operationally enduring, network-dense financial compounding growth narratives in modern enterprise fintech. Founded in 2012, the company grew ARR from $25 million in 2017 to $100 million in 2019 at a $1.7 billion valuation led by a16z, and reached a $7.4 billion valuation following its $500 million Series G led by Silver Lake in 2021. In 2026, Carta achieved an annualized revenue run-rate exceeding $350 million ($350M+ ARR) with strong software gross margins, managing over $3.0 trillion in private corporate equity across 40,000+ companies and administering $130B+ in venture fund AUM, holding a fortress balance sheet ahead of its landmark initial public offering.
