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.

Moesif

  • Free tier is aimed at hobbyists and small projects, limiting scale before paid usage-based pricing applies.
  • Usage-based pricing on the Growth tier can make costs less predictable at high event volumes.
  • Requires instrumenting APIs with SDKs, adding setup overhead compared to zero-config tools.
  • Focused specifically on API analytics rather than full API gateway or design functionality.
