Heirapi works alongside system integrators, managed service providers, and enterprise architecture teams across Australia. We build the custom API layer that connects modern corporate networks to the mainframe systems your clients still depend on.
System integrators and enterprise architects choose Heirapi when a mainframe bridge has to survive production traffic, audit review, and the next decade of change. Here is what they say after the first rollout.
We brought Heirapi in for a CICS-to-cloud migration that had stalled twice with other vendors. Their team mapped the transaction paths in the first week and stood up a working bridge before our internal security review even finished. The handoff documentation was the clearest we have seen from any contractor.
Maxine McDermott, Infrastructure Lead at a national logistics operatorOur AS/400 still runs inventory for three warehouses. Heirapi built an API layer that keeps those sessions alive through failover and network blips. We monitor it daily, and the error rate has stayed flat since the second week of production.
Daisha Fritsch, Integration Architect at a retail distribution groupThe compliance team expected a fight over exposing the mainframe. Heirapi came with mutual TLS, credential vaulting, and field-level masking already configured. Our security review passed without a single rework request.
Mallory Purdy II, CTO at a regional utilities providerMost vendors disappear after the demo. Heirapi left us with runbooks, a support desk that answers in hours, and a named engineer who knows our transaction flow. When we added a new endpoint six months later, the change took one afternoon.
Larry Lakin, Head of Enterprise Systems at a manufacturing firmThey did not need a two-month discovery phase to understand IMS or VSAM. Heirapi's engineers had seen our kind of setup before, so the first design call was about constraints, not basics. That is rare in this market.

We start with a two-week discovery sprint: inventory the mainframe interfaces you expose, the protocols in use, and the data contracts your modern services expect. You leave with a concrete integration roadmap, not a slide deck.
