Where each one falls short

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

RAD Studio

  • Professional edition costs $2,000 for the perpetual license plus $599 for year one maintenance, totaling $2,599 before tax
  • Enterprise edition steps up to $3,400 license plus $1,199 maintenance, and Architect edition to $4,416 license plus $2,183 maintenance
  • The perpetual license only entitles the buyer to updates for one year; continued access to new updates and upgrades requires an annually renewable Update Subscription

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.
