Documented cause
LegacyBridge raised £8.2M from Seedcamp and Notion Capital to automate legacy COBOL-to-cloud migrations. Co-founders Alistair Frome and Priya Nair underestimated the complexity of mainframe environments. Their AI migration engine had a 31% error rate on production code, causing a major incident at Barclays pilot in June 2022. The reputational damage froze all enterprise sales, and the company entered administration in March 2023.
Lesson
“AI-assisted code migration tools must be validated in isolated sandboxes, never live production pilot banks.”
