Modernization at Enterprise Scale

A top-20 US regional bank faced an existential risk: their entire core banking platform — 800 million lines of COBOL written over 40 years — was maintained by a team with an average age of 61. With retirements accelerating and no viable hiring pipeline, the bank needed a credible modernization path.

TranspilerAI deployed an on-premises instance within the bank's secure data center. After a 10-week pilot covering the transaction processing subsystem, the full program was approved. Transformation proceeded in parallel with production operations, with zero downtime.

800M lines transformed to Python in 18 months. The bank reduced its COBOL maintenance headcount dependency by 90% and cut annual mainframe licensing costs by $42M.

A national P&C insurer's policy administration system — the revenue engine processing $8B in annual premiums — ran on 300M lines of COBOL. The system had not been significantly modified in 15 years due to institutional fear of breaking critical business logic.

TranspilerAI's traceability engine gave the insurer's actuarial and compliance teams full visibility into every transformation decision. The semantics-preserving approach eliminated the risk of logic drift that had blocked previous modernization attempts.

Full policy administration system modernized in 14 months. Premium processing speed improved 340% on modern cloud infrastructure, enabling new product launches that were previously impossible on the legacy platform.

A federal agency responsible for processing benefits for 60 million Americans operated on COBOL systems dating to the 1970s. Congressional mandates required modernization, but previous attempts using manual rewrite had failed after 7 years and $400M in spending.

TranspilerAI was deployed in a FedRAMP-aligned, air-gapped environment. The agency's oversight requirements were met through our full audit trail — every transformation decision documented and reviewable by the agency's independent verification team.

Pilot program completed in 12 weeks, covering 50M lines with 100% equivalence validation. Full program approved and underway. First production deployment delivered on schedule — the agency's first successful modernization milestone in a decade.
