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.; Vodeno its actual regulatory backing differs by geography, Aion Bank in continental Europe versus NatWest in the UK, so a customer must understand which entity and licence they are actually contracting under rather than assuming one uniform Vodeno product.
  • They diverge on capability: Aiia covers Bank account data access, Vodeno covers Core banking infrastructure.
  • 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.

Vodeno

  • Its actual regulatory backing differs by geography, Aion Bank in continental Europe versus NatWest in the UK, so a customer must understand which entity and licence they are actually contracting under rather than assuming one uniform Vodeno product.
  • Pricing is entirely unpublished across both the European and UK businesses.
  • The scale of NatWest's investment (up to roughly £120 million) signals a business still working toward profitability, with NatWest itself targeting breakeven within five years of the venture launching, which is a meaningful timeline risk for a customer building long-term infrastructure dependency on it.
  • As banking-as-a-service infrastructure, any customer remains dependent on Vodeno's underlying bank partner maintaining its own licence and risk appetite, which is a layer of dependency beyond Vodeno's own commercial terms.
  • Product scope, such as lending and BNPL availability, may differ between the UK and European entities, so a company operating in both markets should not assume identical capability across the two.
