The short version

  • Each has a real cost: Aiia it is now part of Mastercard rather than an independent company, so a business specifically wanting to avoid card network dependency in its banking infrastructure no longer gets that separation by choosing Aiia.; 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: Aiia covers Bank account data access, 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.

Aiia

  • It is now part of Mastercard rather than an independent company, so a business specifically wanting to avoid card network dependency in its banking infrastructure no longer gets that separation by choosing Aiia.
  • Pricing is not published and requires engaging Mastercard's open finance sales process, which can be a heavier sales motion than dealing with a smaller independent open banking provider.
  • Its strongest bank coverage remains concentrated in the Nordics and Northern Europe, so companies needing dense coverage in Southern or Eastern Europe should verify current bank connectivity before committing.
  • Brand confusion is real: developer documentation, login portals and older case studies still reference "Aiia" while newer Mastercard material refers to "Mastercard Open Banking," and a company researching either name in isolation may miss half the relevant material.
  • As with any open banking platform, reliability still depends on the consistency of the underlying banks' own APIs, which is a systemic industry issue rather than something Aiia specifically controls.

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

Aiia: Is Aiia still an independent company?

No, it was acquired by Mastercard in 2021 and now operates as part of Mastercard Open Finance Solutions, referenced as Aiia Enterprise.

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.

Aiia: Does the Aiia brand still exist?

Yes, in developer documentation and login portals, but the company behind it is Mastercard.

MX Technologies: Does it cover Europe?

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

Aiia: Which banks does it cover?

Around 3,000 European banks, with strongest coverage in the Nordics and Northern Europe.

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.
