Onirem Solutions provides specialist OLYMPIC Banking System support, maintenance and migration services for banks running OLYMPIC, Temenos T24 and Triple'A Plus — so your Core Banking keeps running, and improving.
We focus exclusively on Core Banking — OLYMPIC, T24 and Triple'A Plus. That focus is your advantage.
Our deepest area of expertise. We support banks already running OLYMPIC — keeping the system healthy, stable and aligned with your evolving business needs.
Ideal if your bank runs OLYMPIC and needs reliable, experienced external support — without the cost of a full internal team.
Support and project delivery for banks running Temenos T24 or Transact. From maintenance contracts to complex upgrade and migration projects.
Experienced in both legacy T24 environments and newer Transact deployments across retail and private banking.
Specialist consulting for wealth management platforms running Triple'A Plus TAP or Temenos WealthSuite. Portfolio management, reporting and customisation.
Particularly suited to private banks and asset managers looking to optimise their WealthSuite deployment.
We work best when there is a specific challenge to solve — or ongoing expertise to fill.
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.
Your bank is moving from a legacy system to OLYMPIC. We manage the full migration lifecycle — data mapping, parallel run, UAT and go-live.
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.
Your bank wants to activate a new OLYMPIC module — trade finance, loans, multicurrency — but the internal team lacks the time or expertise.
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.
Your operations team uses OLYMPIC or T24 but lacks structured training. We deliver hands-on, practical sessions tailored to your bank's actual setup.
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.
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.
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.
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."
