Increase

Banking-as-a-Service

Enterprise-grade banking APIs giving technology companies direct access to Federal Reserve, Visa, and Clearing House rails.

Overview

Increase is a developer-first banking infrastructure platform that enables technology companies to programmatically store, move, and reconcile money. Rather than abstracting away the complexity of underlying financial networks, Increase connects clients directly to the Federal Reserve (FedACH, Fedwire, FedNow), The Clearing House (RTP), and Visa as an issuer processor — exposing the full data fidelity and capabilities of those networks via a clean REST API. The company operates its own banking core and holds a dedicated Federal Reserve routing number, functioning as a "parallel core" alongside its FDIC-insured bank partners (Grasshopper Bank N.A., First Internet Bank of Indiana, Twin City Bank, and Core Bank). The platform offers a comprehensive set of financial primitives: ACH (same-day by default), Fedwire, Real-Time Payments (RTP), FedNow, Push-to-Card, check issuance and deposit, flexible bank accounts with unlimited virtual account numbers, and Visa card issuance with real-time authorization controls. All products are delivered via API with SDK support in Node/TypeScript, Python, Go, Java, Kotlin, and Ruby. Customers also get a dashboard for manual operations, compliance submissions, and reporting. Compliance is handled through direct-to-bank partnerships, allowing platforms to design their own KYC/BSA programs specific to their business rather than accepting a one-size-fits-all approach. Increase primarily serves fintech platforms, vertical SaaS companies, and larger technology businesses that need to embed banking functionality at scale — including payroll platforms, spend management tools, insurance software, property management, nonprofit software, and fund administrators. As of early 2025, the company has approximately 4,500 customers (small and mid-size banks and fintechs), stores and processes billions of dollars per month, and is founder-bootstrapped. Notable named customers include Ramp, Check (embedded payroll), CapitalOS, and Ascend (insurance finance automation).
