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.; Treasury Prime a fintech cannot buy Treasury Prime directly since the 2024 pivot, so the sales process starts with finding a sponsor bank willing to take your programme, which adds months and removes most of your negotiating leverage on fees.
  • They diverge on capability: Salt Edge covers Account information, Treasury Prime covers BankOS.

  • A bank replacing a fragile middleware arrangement with a structure where it holds the customer contract and the oversight obligationnot Salt Edge

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.

Treasury Prime

  • A fintech cannot buy Treasury Prime directly since the 2024 pivot, so the sales process starts with finding a sponsor bank willing to take your programme, which adds months and removes most of your negotiating leverage on fees.
  • Commercial terms including minimum deposit balances, reserve requirements and per transaction pricing are set by the bank rather than the platform, so two fintechs on the same software can face materially different economics with no public benchmark.
  • The company cut roughly half its staff in the 2024 pivot, which reduced the teams that supported fintech customers directly and left fintechs relying on their bank for support rather than on the vendor who wrote the software.
  • Bank risk appetite is now the binding constraint, and after the Synapse failure sponsor banks decline programmes in higher risk categories that a middleware provider would once have onboarded, so some business models simply cannot get placed.
  • If your sponsor bank exits the programme or is told by its regulator to reduce fintech exposure, you are migrating your entire deposit base to another institution, and the software being the same at both ends does not make that a small project.

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.

Treasury Prime: Can a fintech buy Treasury Prime directly?

No. Since the 2024 pivot it sells to banks. A fintech contracts with a sponsor bank running BankOS, and the bank sets the terms.

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.

Treasury Prime: Why did it change model?

Regulatory pressure on the tri-party middleware structure, sharpened by the Synapse failure. Examiners want the bank holding the customer contract and the oversight obligation, which is what bank-direct means.

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

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

Treasury Prime: What is OneKey Banking?

A way of spreading deposits across several banks in the network, used for FDIC coverage above a single institution limit and for resilience if one bank exits.

Salt Edge: What does it cost?

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

Treasury Prime: Is pricing published?

No, at neither the bank nor the fintech level. Fintech economics are set by the sponsor bank, so expect wide variation.
