Where each one falls short

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

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.

Treblle

  • No free tier is offered; the entry-level Core plan starts at $233/month billed yearly.
  • Growth and Enterprise pricing is custom and not published, requiring a sales conversation to budget.
  • Core plan is limited to 1 workspace and only 30 days of data retention.
  • SSO and on-prem/BYO cloud deployment are reserved for the top Enterprise tier.

Answered from the vendors’ own pages

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.

Treblle: What does Treblle cost?

Treblle's Core plan costs $233/month billed yearly and covers 5 APIs and 5M requests/month; Growth and Enterprise plans use custom pricing for larger request volumes and advanced features.

Source
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.

Treblle: Is there a free plan?

Treblle does not offer a free tier; it instead offers a no-credit-card demo rather than free ongoing access.

Source
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.

Treblle: How is usage metered?

Plans are metered by number of APIs monitored and requests per minute/month, with the Core plan capped at 500 requests/min and 5M requests/month.

Source
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.
