Thought Machine
Cloud native core banking where products are written as smart contracts
As of 1 September 2026, Thought Machine's pricing is not published; the vendor quotes on request. Vault Core replaces a legacy core with a Python based product engine, so a bank can define a mortgage or savings product as code rather than a vendor change request. Softwr lists it under Technology. Thought Machine is available on Web, API, Cloud.
Overview
What Thought Machine does
Thought Machine builds Vault Core, a cloud native core banking platform, and Vault Payments for payment processing. Its architecture point is genuine: financial products are defined as smart contracts written in Python, executed by the core, so a bank's product team can build and test a new deposit or lending product without waiting on the vendor's release cycle. It runs on Kubernetes on public cloud, is API first, and has no batch overnight processing in the traditional sense. What a buyer must understand is that the technology is the easy half. Core banking replacement means migrating accounts, balances, interest accruals, general ledger postings, statements, regulatory reporting and every downstream integration, usually with a period of running old and new cores in parallel. Realistic timelines are eighteen months at the very fastest for a greenfield digital bank on a narrow product set, and two to four years for a phased migration at an established bank. Most large banks choose a greenfield or new brand approach precisely because migrating the back book is the part that fails. Customers include Lloyds Banking Group, Standard Chartered, JPMorgan Chase's Chase UK brand and a number of digital banks. The trade offs: cost is enterprise scale and quoted per institution, usually on accounts or annual value; the smart contract model requires engineering capability that many banks do not have in house, pushing them to system integrators whose fees exceed the licence; and Thought Machine had two rounds of job cuts as it pushed for profitability, which is a supplier stability question for a system a bank will run for fifteen years.
What people use it for
- A large bank launching a separate digital brand on a clean core rather than migrating the back book
- A bank whose product launches are blocked by vendor change requests on a legacy core
- An institution needing real time balances and postings for instant payment obligations
- A group consolidating multiple country cores onto one multi entity platform

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Thought Machine.
- A core replacement is a two to four year programme at an established bank, and the licence is a minority of total cost against system integrator fees, parallel running and data migration.
- The smart contract model presumes a bank can write and maintain Python financial products, and institutions without that engineering capability end up outsourcing the very flexibility they bought.
- Cloud infrastructure cost sits with the bank and is not trivial at scale, so total cost of ownership comparisons against a hosted legacy core often miss a large recurring line.
- Thought Machine has made two rounds of job cuts pursuing profitability, which is a legitimate supplier stability concern for a system a bank expects to run for fifteen years.
- The functional footprint is core ledger and product engine, so origination, collections, regulatory reporting and channels all come from other vendors, and the integration estate around Vault is the bank's problem to design and own.

Questions people ask
Each answer names the page it came from, so you can check it rather than take our word for it.
Is Vault Core genuinely cloud native?
Yes. It is containerised, runs on Kubernetes on public cloud, and posts in real time rather than in overnight batch.
How long does a migration take?
Eighteen months at the absolute fastest for a narrow greenfield launch; two to four years for a phased migration at an established bank.
Does the licence fee represent the total cost?
No. Implementation, system integration, parallel running and cloud infrastructure typically cost more than the licence over the programme.
