Your legacy portal, modernised in weeks — not years
Legacy debt is your biggest liability
Modernization isn't just about UI. It's about security, speed, and scaling in a regulated landscape.
Trust Erosion
Outdated interfaces and slow performance degrade customer trust, leading to churn in an increasingly competitive fintech market.
High Maintenance
Maintenance costs for monolith systems consume up to 80% of IT budgets, leaving zero room for true digital innovation.
Compliance Risk
Patching legacy software for RBNZ or FMA regulatory updates is slow, error-prone, and exposes your institution to heavy fines.
Our proprietary AI methodology
We use advanced LLMs and automated code translation layers to move from "Legacy" to "Modern" without the typical friction of manual rewrites.
Automated discovery
AI agents map your entire portal architecture, logic, and integration points in days.
Parallel rebuild
We build the new portal in a containerized environment while your legacy system stays online.
Controlled handover
Traffic is migrated in phases, ensuring zero downtime and complete data integrity.
Compliance baked in
Every line of code is automatically audited against current NZ financial regulations.
