Use cases

Situations where banks call us.

We work best when there is a specific challenge to solve — or ongoing expertise to fill.

Ongoing OLYMPIC Banking System support contract

Your bank runs OLYMPIC but doesn't have enough internal expertise to manage it day-to-day. We become your external Core Banking team on a retainer basis.

Typical client: a regional bank with 3–15 branches running OLYMPIC.

OLYMPIC Banking migration from another core

Your bank is moving from a legacy system to OLYMPIC. We manage the full migration lifecycle — data mapping, parallel run, UAT and go-live.

Typical project: 6–18 months. We work alongside your IT team and the vendor.

Temenos T24 version upgrade

Your Temenos T24 environment is several versions behind. We know the pitfalls, the custom code risks and how to keep the upgrade on track and on budget.

Typical challenge: custom modifications that must survive the upgrade.

OLYMPIC Banking implementation — new module

Your bank wants to activate a new OLYMPIC module — trade finance, loans, multicurrency — but the internal team lacks the time or expertise.

Typical timeline: 4–12 weeks depending on complexity.

Pre go-live Core Banking testing & QA

Your bank is about to go live on a new Core Banking system and needs independent testing before cutover. We design and execute full functional test plans.

Ideal when the implementation vendor should not be testing their own work.

OLYMPIC Banking System staff training

Your operations team uses OLYMPIC or T24 but lacks structured training. We deliver hands-on, practical sessions tailored to your bank's actual setup.

Available remotely or on-site, in English, French or Spanish.

What makes us different from a big consultancy.

01

You speak to the expert, not an account manager

At Onirem, the person who answers your call is the same person who configures your system. No layers, no handoffs to junior staff who have never seen OLYMPIC before.

02

OLYMPIC Banking System specialist — not a generalist

Our primary focus is OLYMPIC Banking — we have spent years inside this platform. That depth means faster diagnosis, fewer surprises and no learning curve at your expense.

03

Flexible engagement — retainer or project

Whether you need ongoing monthly support or a defined project with a clear start and end date, we adapt to how your bank works — not the other way around.

04

Global delivery, independent of geography

We work remotely and on-site across Europe, the Middle East, Africa and beyond. Core Banking expertise shouldn't be limited by where your bank is located.

"The biggest risk for a bank is having a Core Banking system nobody fully understands. That's exactly the gap we fill."
