What Newline does

Newline by Fifth Third is an API-first embedded finance platform operated as a division of Fifth Third Bank, National Association. The platform provides enterprise clients—including payment processors, fintech companies, payroll/HR software providers, and accounts payable/receivable platforms—with infrastructure to embed payment, card, and deposit account functionality directly into their products. The core product surface consists of three modules: the Payments API (supporting ACH, wire, book transfers, and real-time payments via The Clearing House RTP network with FedNow planned), Card Programs (BIN sponsorship for commercial credit and prepaid debit cards in virtual and physical formats), and Deposit Accounts/EDAS (bank-owned custodial deposit accounts with pass-through FDIC insurance). Supporting infrastructure includes Virtual Reference Numbers (VRNs), Synthetic Accounts, Bring Your Own Ledger (BYOL) capability, Managed File Transfer, webhook-based event notifications, and a developer Dashboard secured by Okta authentication.

The platform is differentiated by its regulatory foundation as a bank division rather than a standalone fintech, providing enterprise clients with bank-grade compliance, BSA/AML oversight, and FDIC-insured deposit infrastructure. Newline ranks as a Top 10 ACH originator per Nacha 2022 data and #5 card issuer per the Nilson Report No. 1269 (August 2024), with $18 trillion+ in cumulative processed volume backed by $297 billion+ in Fifth Third Bank total assets. SDKs are available in TypeScript, Java, and .NET, with sandbox environments and a recently launched Model Context Protocol (MCP) Server for AI agent integration. The customer base spans hundreds of enterprise brands including Stripe, Brex, AngelList, Trustly, Blackbaud, Nuvei, and Payroc.

Revenue is generated primarily through transaction fees on payment processing, card sponsorship and interchange economics, and deposit account services under custom enterprise agreements. Pricing is not publicly disclosed and operates on a quote-based B2B model. Newline's heritage traces to Fifth Third Processing Solutions, established in 1971, which was later renamed Vantiv and spun off into Worldpay; Newline continues this payments innovation legacy under the Fifth Third Bank umbrella.
