  • They diverge on capability: Tuum covers Modular product structure, 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.

Tuum

  • It is a smaller, younger company than Mambu, so it has fewer live reference deployments and a shorter track record to evaluate risk against.
  • The 2022-era rebrand from Modularbank to Tuum means older funding records, case studies and press coverage appear under a different name, complicating due diligence for anyone unaware of the change.
  • Pricing is entirely unpublished, requiring a sales conversation to budget against competing composable core vendors.
  • Its geographic expansion into DACH and the Middle East is comparatively recent, so support depth and local regulatory expertise in those markets are less proven than in its home Baltic and Nordic base.
  • As with any core banking platform, choosing Tuum is a multi-year infrastructure commitment; switching cores after implementation is a major undertaking regardless of how modular the initial adoption was.

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  • Pricing is entirely unpublished across both the European and UK businesses.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.
