Stablecore connects bank systems to stablecoins, tokenized deposits and digital-asset services. Its partnerships and production milestones are real but varied: bank-specific availability, custody arrangements, adoption and economics require more careful distinctions than the marketing headline.

Stripe combines payment acceptance, platform infrastructure and revenue software with banking partners, stablecoin infrastructure and AI-commerce tools. Its scale is substantial, but payment volume, private valuation, revenue and customer balances measure very different things.

Monarch reports $100 million in ARR and a first acquisition as its product expands. The economics of paid households, data reliability, privacy permissions and the boundary between insight and action define the business.

Version note: Updated the aggregation-provider name to Mastercard Data Connect, formerly Finicity, and corrected the security source’s update date.

Fortiva combines a retail second-look program and general-purpose credit cards within Atlanticus’s bank-partner model. Its commercial claims, borrower terms and parent-company portfolio results describe different populations.

GreenSky’s merchant distribution and bank-originated loans now sit within a Sixth Street-led ownership structure. Product terms, funding evidence and separate federal and state enforcement histories explain more than the financing brand alone.

Kobalt Labs applies AI to the document-heavy work of vendor and fintech-partner oversight. Named customer accounts show implemented uses and reported time savings, while evidence on review accuracy, economics and adoption remains narrower than the company’s broad automation claims.

A primary-source company profile of Kalshi’s exchange and clearing structure, private funding, transaction economics, product expansion and unresolved federal, state and tribal legal boundaries.

Version note: Corrected the petition’s court label to the U.S. Supreme Court.

Version note: Replaced legacy documentation links with specific current documentation and aligned the description of funding-source approval.

Airwallex connects business accounts, foreign exchange, payment acceptance, payouts and spending tools. Its rapid growth is supported by local authorisations and bank relationships, but payment volume, annualised revenue, safeguarded funds and investment products describe different parts of the business.

Antithesis runs software in a controlled simulation to expose and reproduce difficult failures. Its financial relevance lies in testing stateful systems and accelerating debugging, while its usefulness depends on the properties, workloads and dependencies included in the test.

Aven packages asset-backed borrowing in familiar card and app interfaces. Its home-equity products, newer Bitcoin line and co-brand expansion illustrate both the appeal of lower-friction credit and the importance of separating collateral risk, bank responsibilities and promotional savings claims.

Cardless supplies embedded credit-card infrastructure and servicing for brands including Bilt, Coinbase and airlines. Its role is substantial, but it is not the issuing bank, and neither program growth nor prominent partnerships disclose the company’s retained economics or credit exposure.

Circle issues USDC and EURC through regulated affiliates and is building payment, custody and blockchain infrastructure around them. Reserve income still dominates the economics, while distribution agreements, redemption access and jurisdiction-specific rules shape both the business and the risks.

Cursor is Anysphere’s AI software-development platform. Following its August 2026 acquisition by SpaceX, the relevant questions include model strategy, enterprise economics, cloud-agent data boundaries and whether faster engineering produces dependable financial software.

equipifi supplies the software behind bank- and credit-union-branded installment plans on existing debit cards and checking accounts. Its expansion illustrates how institutions can retain the lending relationship, while the evidence on adoption, credit performance and customer benefits remains more qualified than the BNPL label suggests.

A primary-source company profile separating Polymarket US from its international platform, including collateral, resolution, current fees, ICE’s investment, data distribution and legal risk.

Revolut combines payments, subscriptions, foreign exchange and investing with an expanding network of licensed banks. Its scale is substantial, but the company, legal entity, account type and country remain essential to understanding its economics and customer protections.

Settle combines purchasing, accounts payable and short-term financing for consumer brands. Its operating data can make funding more convenient, but product-specific contracts, funding costs and credit outcomes determine the economics; the U.S. company is separate from the Norwegian Settle acquired by Sokin.

Upstart combines automated credit decisions with loan distribution, servicing and its own capital. Its improving 2026 earnings sit alongside material balance-sheet exposure, uneven loan-vintage returns and a conditionally approved bank that has not been verified as operational.

Veritus builds voice, text and email agents for loan applications, servicing and collections. Its customer examples show how automation can recover missed conversations and reduce friction, while raising important questions about measurement, payment authorization, personal-data handling and the boundary between software controls and legal compliance.

Voyager AI develops document and workflow software for community lenders. Its $500,000 pre-seed financing and advisory case study establish an early record, while production adoption, customer economics and several assurance claims still require closer verification.

Parafin embeds working capital, financing for business purchases and revolving cards into business software. Its pending Stripe acquisition brings attention to a model built on platform data, several bank relationships and capital-market funding, with important differences between sales-based payments, bank loans and cash advances.

FIS entered 2026 with a different portfolio: its Worldpay ownership ended and Global Payments’ issuer business became Total Issuing Solutions. The new scale makes financial comparability, integration and cash generation central.

Galileo’s 2026 transition to SoFi Tech Solutions joins processing and core-banking capabilities under a broader brand. Customer attrition, intercompany activity and product mix complicate its scale metrics.

Imprint combines card-program technology and loyalty design with bank-issued consumer credit and capital-markets funding. The model links merchant engagement to a receivables business whose economics cannot be judged from rewards or funding headlines alone.

Mercury links operating accounts, payments, cards and financial workflows through partner institutions. Its proposed national bank adds a new strategic direction, but conditional regulatory approvals are separate from permission to open.

Ramp combines corporate cards with finance software, payments and cash-management products. Its scale is growing quickly, but annualized volume, software adoption, credit exposure and private-market valuation describe different parts of the business.

Plaid connects financial accounts to applications, then sells verification, payment and analytical services around those connections. Its growing business depends on reliable access, useful data and clear boundaries between Plaid Inc., Plaid Check and the institutions that move or hold money.

Bilt’s housing distribution, redesigned card program and property software create a broad commerce opportunity. The central questions are partner responsibility, usable rewards, reliable payments and economics beyond private-company growth claims.

Chime’s public filings reveal a payments-led consumer platform with growing liquidity revenue and recent profitability. Its proposed Stride purchase could change infrastructure ownership, while lending risk, interchange economics and service quality remain central.

Affirm connects merchants and shoppers through short and longer installment plans. Its economics combine merchant payments, consumer interest and capital-market funding rather than a single pay-in-four model.

Afterpay links retail checkout and Block’s consumer ecosystem. Its U.S. products include no-finance-charge installments, finance-fee loans and monthly financing with materially different terms.

Cherry connects healthcare and other service providers with customer financing. Its bank-originated loans and merchant-originated installment contracts require different legal and economic descriptions.

Klarna combines a regulated European bank with checkout financing, merchant services and growing card distribution. Product economics and legal lenders differ by market and payment plan.
