  • Each has a real cost: Skaleet the installed base is in the tens rather than the hundreds, so the pool of consultants and systems integrators who know the platform is small and expensive.; 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: Skaleet covers Cloud-native core, Treasury Prime covers BankOS.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Skaleet

  • The installed base is in the tens rather than the hundreds, so the pool of consultants and systems integrators who know the platform is small and expensive.
  • Speed references are mostly greenfield launches inside large groups, which is an easier problem than migrating an existing book off a legacy core.
  • It is European-centric, with payment rails and regulatory work concentrated on SEPA and EU requirements rather than global coverage.
  • As a smaller vendor carrying a bank core, it attracts hard concentration and viability questions in procurement that larger competitors do not face.
  • Pricing is unpublished and scaled by accounts and transactions, so a bank whose volumes grow faster than forecast faces cost escalation it did not model.

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

Skaleet: What was Skaleet called before?

TagPay. The company rebranded to Skaleet while keeping the same platform lineage.

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.

Skaleet: Can I buy just the payment hub?

Yes. The payment engine is licensable standalone and can sit over an existing core, which is a common first step.

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.

Skaleet: How fast are real deployments?

Named European deployments have gone live in six to twelve months, including a Crédit Agricole savings platform live in Germany in eight months.

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.

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.
