Monument Technology Partners with Castle Trust Bank for Cloud-Native BPaaS
Monument Technology announced on Apr 24, 2026, a partnership with Castle Trust Bank to deploy its cloud-native BPaaS platform across the bank's savings operations. Castle Trust Bank, which received full regulatory status in 2020, will transition its savings business onto the platform as part of a broader push to modernize its technology infrastructure. The migration is already under way, with completion targeted for early 2027.
The deal is Monument Technology's second client win and its first with a UK-regulated bank. It follows the company's full deployment with Ecology Building Society, confirmed earlier in April. Castle Trust Bank plans to use the platform to support growth and introduce a new Easy Access product range.
Financial terms were not disclosed.
- Validates demand for managed BPaaS solutions among mid-tier UK banks seeking to replace legacy core systems
