Legacy software. Diagnosed and futureproofed.

We help organisations audit, understand, and modernise fragile systems built in VB6, Delphi, .NET, C++, and more.

Our Services

Legacy Analysis

We dive deep into your existing software to uncover risks, inefficiencies, and hidden dependencies. Our audits are jargon-free, practical, and designed for decision-makers, giving you a clear picture of where you stand and what actions to take to improve system stability and longevity

Risk Mitigation

Outdated systems often carry invisible risks. We identify the weak points, from security flaws to single points of failure, and give you a tailored roadmap to reduce downtime, avoid data loss, and extend the lifespan of your critical software infrastructure with minimal disruption.

Migration & Modernisation

Whether you're migrating away from unsupported platforms or simply updating outdated components, we help you modernise safely. Our approach avoids rip-and-replace chaos: We work with what you have, ensuring a controlled evolution that respects your workflows, data, and internal tooling.

Advisory Support

Need a second opinion or strategic guidance? We offer clear, honest advice on legacy system decisions, vendor proposals, and technical planning. Whether you need a few hours or ongoing input, our advisory support gives you clarity without the upsell. Just expert help, on call.

Development That Fits Your System - Not the Other Way Round.
When diagnostics reveal deeper issues, we offer a clear path forward:

Source-based enhancements when legacy code is viable
Behavioural reimplementation where the original source is missing
Targeted rebuilds only when modernisation isn’t feasible

Our goal is simple: extend the life of your systems where possible, and replace only when necessary; With minimal disruption and maximum clarity.
