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.

Swan

  • Its regulatory base and strongest local account coverage are French and European, so companies needing US, UK-post-Brexit-specific, or broader global banking-as-a-service need an additional provider.
  • Pricing is described only philosophically (usage-based, no big setup fee) rather than published as an actual rate card, so a company still needs a sales conversation to get real numbers.
  • Embedding banking features into a product is a substantial compliance and design undertaking regardless of the vendor, and Swan handling the licence does not remove a platform's own KYC, AML and customer support obligations for the accounts it offers.
  • As a comparatively young, single-country-licensed e-money institution, its balance sheet and regulatory standing carry more concentration risk than a banking-as-a-service offering backed by an established, multi-jurisdiction bank.
  • Local account depth is explicitly limited to France, Germany and Spain, so a platform needing native local accounts in other European countries may find coverage thinner than expected.
