The short version

  • Each has a real cost: MX Technologies coverage is United States focused, so any product with European or other international users runs a second aggregator and reconciles two data models, which removes most of the single vendor argument.; 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: MX Technologies covers Account aggregation, 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.

MX Technologies

  • Coverage is United States focused, so any product with European or other international users runs a second aggregator and reconciles two data models, which removes most of the single vendor argument.
  • Nothing is published on price and contracts are enterprise shaped, so a small fintech cannot estimate cost or start building without a sales process, unlike self-serve competitors.
  • Data enhancement is the differentiator and is licensed separately from aggregation, so the quoted aggregation price is not the price of the product people actually buy it for.
  • Categorisation and merchant resolution are statistical and get business to business and unusual transactions wrong more often than consumer retail, so lending decisions built on categorised data need their own review layer.
  • As the United States moves to regulated API access, connection quality depends on what each institution exposes, and the long tail of small banks and credit unions remains the weakest part of any aggregator including this one.

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  • Pricing is entirely unpublished, requiring a sales conversation to budget against competing composable core vendors.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

MX Technologies: What does MX do that Plaid does not?

It sells transaction cleansing, categorisation and merchant resolution as a first class product, including on data you already hold, which is why financial institutions rather than startups are its core customers.

Tuum: Is Tuum the same company as Modularbank?

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

MX Technologies: Does it cover Europe?

No. MX is United States focused. European coverage requires a different provider such as Tink.

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.

MX Technologies: Is pricing published?

No. Contracts are quoted by connected users, call volume and modules, with enhancement licensed separately from aggregation.

Tuum: Is pricing published?

No, subscription and module pricing require a sales conversation.

MX Technologies: Does it use screen scraping?

It uses direct bank APIs where institutions expose them and credential based connections elsewhere. The credential path is being deprecated across the industry, and coverage quality now tracks which banks have real APIs.
