AI, APIs, and modernisation for IBM-stack enterprises.

We help IBM i, Power, and midrange Unix/Linux teams ship greenfield AI agents, build the APIs that connect them, and move off legacy on their own timeline — not a vendor's.

01 / Agentic AI

Greenfield AI implementations

Local and frontier models, working together on real codebases. We stand up agentic development setups that respect data residency, run behind your firewall, and ship production code — RPG, COBOL, Java, Python.

02 / APIs

API implementations

Modern APIs over IBM i and Power workloads. Architecture, gateway, governance, and the integration plumbing that makes legacy systems first-class citizens in your platform.

03 / Legacy

Legacy systems work

Twenty-year-old systems aren't going anywhere fast. We make them visible, testable, and progressively replaceable — without the all-or-nothing rip-and-replace pitch.

Who we work with

Enterprise IT teams running serious estates.

IBM i shops with decades of business logic in RPG. Power-based Unix estates that have outgrown their integration story. Linux midrange teams who want to add AI without handing their data to a third party.

We've spent careers in this stack. We know what breaks at 3am, and we know what doesn't need to be replaced.

# a typical engagement
  • assess the estate, the appetite, the constraints
  • pick one thing worth doing well
  • stand up the agents, the APIs, or both
  • hand it over — or stay and help operate it
Our product · Mission Control

Governed AI delivery, not autonomous chaos.

Mission Control is the control plane we've built for running AI delivery teams inside enterprises. Business demand becomes approved, auditable work packages. AI workers execute in controlled lanes. QA evidence and policy gates decide what ships.

  • PIP intake & release packs
  • Server-side RBAC
  • Tamper-evident audit ledger
  • Policy-as-code release gates
  • Supervised dispatch gate
  • Sandboxed worker lanes
