Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Griffin
- Platform banking carries a one-off onboarding fee from 15,000 pounds and a 3,500 pound monthly minimum, which prices out early-stage companies entirely.
- It is UK-only, so a business with European or US operations needs a second banking provider and a second integration for those entities.
- It is a young bank with a small balance sheet relative to incumbents, and enterprise counterparties still ask hard questions about concentration risk.
- Holding a banking licence means Griffin applies bank-grade due diligence to its own clients, so onboarding is slower and more selective than an EMI-based provider.
- Feature breadth is narrower than long-established providers, particularly in card programme management and in payment types beyond core UK rails.
RapidAPI
- RapidAPI Enterprise Hub minimum seat requirement is 5 seats per the embedded pricing page configuration (SEATS_MINIMUM: 5).
- RapidAPI places a $0.50 USD temporary credit card authorization hold when subscribing, refunded only if no overage charges occur within 7 days.
