The short version

  • Each has a real cost: Neonomics coverage outside the Nordics and the UK is comparatively shallow, so a pan European merchant will find gaps and inconsistent bank behaviour in southern and eastern markets.; 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.
  • They diverge on capability: Neonomics covers Payment initiation, Tuum covers Modular product structure.
  • 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.

Neonomics

  • Coverage outside the Nordics and the UK is comparatively shallow, so a pan European merchant will find gaps and inconsistent bank behaviour in southern and eastern markets.
  • It is a small company relative to Tink and TrueLayer, so supplier viability and the depth of engineering support behind bank API changes are genuine procurement questions.
  • Payment initiation only means the merchant handles settlement, reconciliation and refunds, and there is no chargeback framework to fall back on.
  • Integrating a recently acquired UK business means two regulatory entities and, for a period, two technology stacks, so cross market feature parity is a promise rather than an existing state.
  • Conversion is governed by each bank's own authentication experience, and Nordic BankID flows behave differently from UK app redirects, so a single UX cannot be assumed across the footprint.

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  • Pricing is entirely unpublished, requiring a sales conversation to budget against competing composable core vendors.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.
