COBOL → Modern APIs · Verified field-for-field

We modernize the mainframe and prove, field by field, that nothing was lost.

01 · The machine

Forty years old. Trillions in force. Nobody dares touch it.

Your policy systems were written before the web, in COBOL, by people who have since retired — and they still run the business. Flip a copybook to JSON with a careless script and the damage is invisible: a packed-decimal premium becomes a string, a twelve-element array collapses to one. Nothing errors. The numbers just quietly stop matching.

02 · The dissection

We don't migrate the machine. We dissect it — and prove every field.

Ironparse opens the record like a teardown. A deterministic parser emits a typed schema and runs five gates — each field turning silver to gold only once it clears, while the fields a careless migration would lose drop away in red. It all runs inside your perimeter: zero bytes leave the room. Out comes clean REST/JSON and a signed parity receipt. Click any part to inspect it.

03 · Pilot engagement

From $250k, deployed inside your perimeter.

Scoped to one policy-admin system or copybook set, delivered with a full parity report. The pilot ends with a receipt that proves the migration lost nothing.
