"We had a CICS region that nobody wanted to touch. Heirapi mapped the transaction boundaries first, then built the REST facade. The first cutover ran for three weeks without a single abend. That alone changed how our ops team viewed the project."

"The security review was the part I dreaded. They came back with mutual TLS on every endpoint, short-lived tokens for the service account, and a clear audit trail on both sides of the bridge. Our compliance team stopped asking questions after week one."

Platform director, utilities provider
"What sold me was the way they handled the batch-to-real-time shift. Instead of a big bang rewrite, they ran the nightly job and the live API side by side for a month. When the numbers matched, we switched off the batch process for good."

Head of enterprise architecture, manufacturer
"Our mainframe team is small and protective of the old system. Heirapi documented every data mapping and every error code before touching production. That level of respect for the legacy environment made the whole engagement painless."

Senior backend engineer, retail group
"The API bridge now handles about 40,000 calls a day without a hiccup. Latency sits around 80 milliseconds, which is fine for our warehouse scanners. We went from a fragile point-to-point link to something we can actually monitor and scale."
