The short version

  • Each has a real cost: Salt Edge coverage outside regulated open banking markets is not all direct bank API, and connections that are not regulated interfaces break when a bank changes its systems, so a headline country count overstates the reliability you will actually experience.; 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: Salt Edge covers Account information, 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.

Salt Edge

  • Coverage outside regulated open banking markets is not all direct bank API, and connections that are not regulated interfaces break when a bank changes its systems, so a headline country count overstates the reliability you will actually experience.
  • Pricing is not published and is usage-based, so two providers cannot be compared without running both sales processes, and cost grows with the connected user base rather than with revenue.
  • Support and engineering are distributed across Eastern Europe and Canada, and buyers in other time zones report slower turnaround on connection-specific breakages than they get from a domestic provider.
  • PSD2 consent rules require customers to reauthenticate periodically, and Salt Edge cannot change that, so any product depending on continuous data must design for consent expiry and the drop-off it causes.
  • United States coverage is weaker than Plaid or Mastercard Open Banking, so a company with meaningful US volume ends up running two aggregators and normalising between them.

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  • Pricing is entirely unpublished, requiring a sales conversation to budget against competing composable core vendors.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

Answered from the vendors’ own pages

Salt Edge: Who owns Salt Edge?

It is independently owned, unlike Tink (Visa), Finicity (Mastercard) or Yodlee (Envestnet), which matters if your use case competes with the owner.

Tuum: Is Tuum the same company as Modularbank?

Yes, Modularbank rebranded to Tuum; it is the same company and platform.

Salt Edge: Is all coverage direct bank API?

No. Inside PSD2 markets connections use regulated APIs; elsewhere coverage relies on direct connections whose reliability depends on the bank not changing its systems. Ask for a per-institution answer.

Tuum: Where is it strongest geographically?

Its base is Estonia and the Nordic and Baltic region, with newer expansion into DACH and the Middle East.

Salt Edge: Does it do payments as well as data?

Yes, payment initiation is supported in European markets where PSD2 applies.

Tuum: Is pricing published?

No, subscription and module pricing require a sales conversation.

Salt Edge: What does it cost?

Not published. Pricing is usage-based and quoted, though the sandbox is free.
