Trusted core. AI-powered apps all around it.

We rebuild the screens, workflows and integrations around your core system on OutSystems, so you get modern apps without risky core changes.

AI discovery in progress

What Core Modernization means.

Most banks can’t replace their core in one go, and don’t need to. We keep your core banking system as the system of record and rebuild everything around it: the screens, workflows, integrations and data access your teams and customers use every day.

Map

AI reads your legacy code and finds the business rules, screens and integrations.

Connect

Modern APIs and OutSystems Data Fabric give new apps safe access to core data.

Rebuild

Old screens and workflows become fast, modern apps on ODC.

Retire

Old systems are switched off one module at a time, only once the new one is proven.

How a modernization runs.

Small, tested steps. Your core never stops.

Retire

Run old and new in parallel, then switch off the old module.

How OutSystems does the heavy lifting.

Each part of the modernization runs on a specific OutSystems capability.

OutSystems Developer CloudODC

What it isOutSystems’ cloud-native platform. Apps run as independent services that scale automatically and ship on their own.

How we use it hereEach modernized module is its own app, released on its own without touching the rest.

MentorAI coding agent

What it isOutSystems’ platform-native AI agent. Describe what you need and it generates apps, AI agents, workflows and libraries for engineers to review.

How we use it hereOld screens and business rules are rebuilt faster. Every generated piece is reviewed by our engineers.

Data FabricData layer

What it isA single virtual layer over your databases, APIs, legacy systems and SaaS apps. Data stays where it is and keeps its permissions.

How we use it hereNew apps read core banking and legacy data in place, without risky data copies.

Agent WorkbenchAI agents

What it isBuilds and orchestrates AI agents across your data, workflows and systems, with built-in human oversight. Plug in any major LLM.

How we use it hereRebuilt journeys get AI agents, like a servicing agent that drafts replies for staff.

Governance & MCPControl

What it isODC roles, approvals and audit trail, which also apply when engineers build and ship through OutSystems MCP.

How we use it hereEvery change is tracked, approved and can be rolled back.

Questions banks ask us.

Do we have to replace our core banking system?

No. Your core stays as the system of record. We modernize the apps, workflows and integrations around it.

How is AI used, and who checks the result?

AI scans legacy code and helps generate first versions through Mentor. Our engineers review, test and secure everything before it goes live.

Which core systems do you work with?

Any core that exposes APIs or a database we can safely read. We connect through your core’s APIs, or through OutSystems Data Fabric where it fits.

How long before we see something live?

Usually the first module is live within the first wave. Your exact timeline comes out of the two-week discovery.

Start with a two-week legacy discovery.

We map your legacy estate with AI and show you the safest modernization path.
