The Problem
Why modernisation keeps getting delayed
Fear of breaking what works
Business-critical logic is buried in undocumented COBOL, VB6, or custom-built applications. The risk of touching it feels too high – so it never gets touched.
Knowledge locked in retiring staff
The engineers who built these systems are leaving. With them goes institutional knowledge that has never been documented, tested, or reviewed.
Cloud integrations that stop at the edge
You’ve invested in SaaS and cloud tools, but they can’t talk to your core systems. Data flows are brittle, manual, or don’t exist at all.
Compliance exposure from unsupported software
Systems running on end-of-life platforms create GDPR, security, and audit risk – particularly critical for Global enterprise operations.
Our Approach
Modernise with surgical precision
We don’t rip-and-replace. We assess, extract, refactor, and migrate – in parallel with your live operations. Your business never stops.
Codebase Archaeology
Automated scanning and manual analysis of your existing systems to map dependencies, data flows, and hidden business rules.
Strangler Fig Migration
Replace legacy components incrementally while keeping the old system live. Zero-downtime, continuously deliverable modernisation.
Cloud-Native Replatforming
Re-architect core modules as containerised microservices on AWS, Azure, or GCP – designed for Global data residency requirements.
API-First Integration Layer
Wrap modernised components in clean REST or GraphQL APIs, enabling seamless connectivity with your Salesforce, SAP, or data platform.
Delivery Methodology
How we deliver
Discovery & Risk Assessment
2-4 week deep-dive: codebase scan, stakeholder interviews, dependency mapping, and GDPR/compliance risk identification. Deliverable: modernisation roadmap and business case.
- Weeks 1-4
- Risk-Free
Proof of Concept
Isolate the highest-risk module and modernise it first. Validate the approach on a non-critical component before full commitment.
- Weeks 4-8
- Validated Approach
Iterative Migration Sprints
2-week sprints migrating modules in priority order. Parallel running of old and new until functional parity is confirmed by your QA team.
- Sprint-Based
- Continuous Delivery
Cutover & Stabilisation
Planned cutover weekend, hypercare support for 30 days post-launch, and full documentation handover to your internal team.
- Zero Downtime
- 30-Day Hypercare
