AI can rewrite legacy code. But rewriting was never the hardest part.

The real challenge is proving a modernized system behaves exactly like the original. For regulated institutions, that means validating every payment, account, settlement, and reporting workflow and producing a defensible audit trail for regulators, boards, and auditors.

The risk isn't in COBOL, RPG, or ABAP. It's in the decades-old business logic buried inside core systems: undocumented, mission-critical, and often understood only by engineers nearing retirement.

Newcoda gives your enterprise back control of the code it depends on. We migrate the systems your business runs on and prove nothing changed but the code with evidence before cutover.

LLMs are non-deterministic and can't guarantee equivalence our deterministic engine can. 35 years of proven migration experience. Proof written into the contract: a pre-agreed validation target defines success auditable, not "trust us."

Our Provable-Equivalence Guarantee: the migration is complete when the agreed inputs and outputs match, in writing.

Newcoda is built for regulated institutions in critical industries: banks, insurers, and government and state entities running legacy cores.
