The calm way off the mainframe.
Reverse-engineer the estate, extract the rules with receipts, and forward-engineer what comes next — without waking the systems that run your business.

which one are you?
the estate
Beneath every bank, every insurer, every government hums an estate the cloud never reached — sixty years of decisions, written in a language the world stopped teaching.
2.1m lines is a Tuesday · the average estate is older than its maintainers
three pressures
Why this stopped being tomorrow’s problem.
The people who can read it are leaving.
The engineers who built these systems are retiring. Every departure takes uncopied knowledge with it — and it isn’t coming back.
Your transformation is stuck behind it.
The ERP program, the cloud program, the merger — every roadmap stops at the same dependency no one can untangle.
Your AI strategy can’t get in the door.
Every AI initiative needs the business logic. The business logic lives in code your models can’t parse and your people can’t explain.
so we set it free
Your most important code is the code no one can read.
