The short version

  • Each has a real cost: IAR Embedded Workbench no pricing information published on product page; prospective customers directed to free trial or sales contact only; 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.

Where each one falls short

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

IAR Embedded Workbench

  • No pricing information published on product page; prospective customers directed to free trial or sales contact only
  • Pricing model not specified; customers must request quote or try free trial to understand licensing costs
  • Embedded development tools typically require expensive licenses, but specific IAR costs unavailable online

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.
