Experts in migrating, modernising and running your legacy systems.
An AI managed service for legacy estates, delivered on Swiss data servers. We extract decades of policy data and business rules from COBOL, DB2, Oracle, RPG on AS/400 and Progress OpenEdge, prove them correct, and run what remains.
Before you modernise
What happens to thirty years of decisions when the person who made them retires?
The why behind your system was never written down. It retires when your experts do. We capture it while they can still confirm it, then modernise, and hand you documentation that stands up to a regulator. That question has a deadline. Qubiz is the answer before it passes.
Discovery
Capture what lives in people's heads
We interview your domain experts and reverse-engineer decades of undocumented decisions before they walk out the door.
Migration
Move forward without losing the past
We migrate your data and modernise your code with zero-loss precision — every business rule accounted for, every edge case tested.
Operations
Run it so your team does not have to
We operate the modernised system in the transition period, keeping your business live while your people get up to speed.
Insight
Turn legacy data into business intelligence
We structure and surface your historical data as analytics and reports your actuaries and executives can actually use.
Technologies We Modernise
No guessing whether your system qualifies.
If your platform runs on one of these, or a combination as decades of mergers usually produce, we know it.

How we help, in the order you usually ask for it.
Each service is commissioned standalone or as part of a wider migration programme. Most clients start with a data migration and add code modernisation as the scope becomes clear.
A unified, auditable data foundation your systems can act on.
Legacy policy data extracted with full temporal history preserved, validated against source across the whole timeline, so nothing rests on a flattened snapshot.
The disciplines that make a migration land.
A foundation your analytics can trust.
Analytics and automation fail on undocumented systems and data whose accuracy no one can confidently confirm. We fix that first: logic recovered from the code, historical data cleaned up, and a well-modelled data lake with every rule documented and every record accounted for. The clever layer on top is only as good as the foundation underneath it — which is the part we build.
Surprises belong in the rehearsal, not the performance.
A core migration for an insurer, a pension fund, or a bank happens once. We baseline your live source, re-run it in parallel against the new system, and reconcile premiums, reserves, and balances before a single switch. We find every place a load would fail or lose information — in advance, against real data. Validation is exhaustive and multi-period, edge cases come from the specification rather than memory, and a tested rollback stays in the plan.
Security by construction.
The fear is reasonable: AI that writes plausible, insecure, wrong code that isn't caught in time. Every consequential decision and every line of code is reviewed and signed off by our engineers. Generated code clears static analysis, security scanning, and automated tests before it goes anywhere near your codebase. Verification is deterministic, so it never depends on the model being right. The AI does the typing. It does not get the final word.
We work inside your walls.
For sensitive environments we operate inside your infrastructure, under your controls, monitoring, and change management. Your data does not leave the building to get the job done, and our footprint stays minimal. FINMA, the revised FADP, and banking confidentiality mean data often cannot leave the country — we resolve that with Swiss-resident data and delivery from a 350-strong European team.
The Reconciliation Files
Happening every day in financial services —
told by the people who had to put their name on the number.
The Ghost in the Stored Procedure
One undocumented change to a 30-year-old NPV calculation put six years of technical reserves — and my signature — on the line.

Speak with someone who has sat across from an underwriter.
Every insurance engagement starts with the underwriting workflow, the actuarial hypothesis, and the model-risk framework — not the technology stack. No discovery decks, just an honest conversation.
