The short version

  • Each has a real cost: 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.; MX Technologies coverage is United States focused, so any product with European or other international users runs a second aggregator and reconciles two data models, which removes most of the single vendor argument.
  • They diverge on capability: Griffin covers Bank accounts by API, MX Technologies covers Account aggregation.
  • Prices and features above were last checked on 1 September 2026.

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.

MX Technologies

  • Coverage is United States focused, so any product with European or other international users runs a second aggregator and reconciles two data models, which removes most of the single vendor argument.
  • Nothing is published on price and contracts are enterprise shaped, so a small fintech cannot estimate cost or start building without a sales process, unlike self-serve competitors.
  • Data enhancement is the differentiator and is licensed separately from aggregation, so the quoted aggregation price is not the price of the product people actually buy it for.
  • Categorisation and merchant resolution are statistical and get business to business and unusual transactions wrong more often than consumer retail, so lending decisions built on categorised data need their own review layer.
  • As the United States moves to regulated API access, connection quality depends on what each institution exposes, and the long tail of small banks and credit unions remains the weakest part of any aggregator including this one.

Answered from the vendors’ own pages

Griffin: Is Griffin actually a bank?

Yes. It received a UK banking licence with restrictions in March 2023 and a full licence in March 2024 after exiting mobilisation.

MX Technologies: What does MX do that Plaid does not?

It sells transaction cleansing, categorisation and merchant resolution as a first class product, including on data you already hold, which is why financial institutions rather than startups are its core customers.

Griffin: What does it cost?

Business banking from 100 pounds a month; platform banking from a 15,000 pound onboarding fee plus a 3,500 pound monthly minimum drawn down by usage.

MX Technologies: Does it cover Europe?

No. MX is United States focused. European coverage requires a different provider such as Tink.

Griffin: Does it cover Europe?

No. Griffin is a UK bank serving UK accounts and UK payment rails.

MX Technologies: Is pricing published?

No. Contracts are quoted by connected users, call volume and modules, with enhancement licensed separately from aggregation.

MX Technologies: Does it use screen scraping?

It uses direct bank APIs where institutions expose them and credential based connections elsewhere. The credential path is being deprecated across the industry, and coverage quality now tracks which banks have real APIs.
