  • They diverge on capability: Aiia covers Bank account data access, Column covers National bank charter.
  • 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.

Column

  • Column publishes no pricing whatsoever, so there is no way to model cost before a sales process, and terms are negotiated per programme which favours larger, more sophisticated buyers.
  • Onboarding is bank diligence rather than vendor sign-up, and programmes routinely spend several months on compliance review, flow of funds documentation and volume forecasting before the first live transaction.
  • Column selects its customers and declines many, so the charter advantage is only available to programmes it considers acceptable risk, which excludes most early-stage teams.
  • It is United States only, so any programme with international account or local payment needs must add a second banking relationship and reconcile across both.
  • Being the bank means Column also carries the bank's regulatory constraints, so product changes that affect risk, such as new customer segments or higher-risk flows, need approval rather than a configuration change.

Answered from the vendors’ own pages

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

Column: Is Column actually a bank?

Yes. It is a nationally chartered, FDIC-insured bank, which is why there is no sponsor bank behind it.

Aiia: Does the Aiia brand still exist?

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

Column: How is that different from Synctera or Unit?

Those are technology providers that connect you to a separate sponsor bank. With Column the API provider and the depository institution are the same company.

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

Column: What does Column cost?

Nothing is published. Pricing is negotiated per programme.
