A small UK team, working deep in the IBM stack.
Plexicate is a technical consultancy for enterprise IT teams. We've spent careers around IBM i, Power, AIX, and Linux midrange — building integrations, writing the APIs that connect them to the rest of the business, and now helping those teams adopt AI without giving up control of their data.
Honest scoping, then steady delivery.
Most projects start with a short discovery: a couple of calls, access to the right people, and a written view of the estate and the options. From there we either move into delivery, or we tell you why we're not the right team — and who might be.
We work as an extension of your team, not as a black-box vendor. Code, decisions, and architecture stay yours.
We turn down work that isn't a fit. A short engagement that lands beats a long one that drifts.
Old systems get a bad reputation. We modernise the parts that genuinely block progress and leave the rest alone.
Enterprise data doesn't need to leave your network to benefit from agentic workflows. We design for that constraint from the start.
Decisions, trade-offs, and the things that didn't work — written down. Nobody should be surprised six months later.
Head office in London, with administration and HR in Weybridge. We work with clients across the UK and Europe.
IBM i, Power, AIX, Linux on Power, IBM API Connect, DataPower, MQ, Db2 for i, RPG, COBOL, plus the modern web/AI stack we use to bridge between them.
