Where each one falls short

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

Episode Six

  • Deployment on premise or in a private tenancy means the institution carries infrastructure, upgrade and PCI scope work that a hosted processor would absorb.
  • Implementation runs to quarters and involves core banking, network certification and fraud system integration, so time to first card is far longer than with a self serve issuer processor.
  • Pricing is entirely bespoke and weighted to large programmes, which prices out fintechs and small issuers who would be better served by a hosted platform.
  • Being smaller than the incumbent processors, its network certifications and operational presence vary by region, so a global rollout can find gaps in specific markets.
  • The flexibility of six hundred APIs and a configurable product engine shifts design responsibility onto the buyer, and institutions without strong internal payments architects end up dependent on professional services.

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

Episode Six: Can Episode Six run inside our own data centre?

Yes. On premise and private cloud deployment is the main reason banks choose it over hosted only processors.

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.

Episode Six: Is it suitable for a startup issuing its first cards?

Not really. The licence, implementation timeline and cost are aimed at banks and large institutions.

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.

Episode Six: Do we still need a card licence or sponsor?

Yes. Episode Six is a processor. Network membership, licensing or a sponsor arrangement remains your responsibility.

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.
