Bring your critical system into the modern era — without disruption.
We build around the proven core, incrementally, persona by persona. The business keeps running the whole time, and each piece ships the moment it's done — no big-bang gamble, no cut-over weekend.
The system works. That's exactly what makes it hard to touch.
Our core system is decades old — and the people who built it are gone.
A rewrite means a cut-over weekend the business can't survive.
Nobody can tell us what the system actually does anymore.
The last modernization ran for years and shipped a coat of paint.
Don't migrate the software. Modernize the business.
A migration that moves the same workflows to a newer stack is money spent for no new value. Every piece of work we take on has to answer one question first: what capability or revenue does this unlock?
Build around the core, not instead of it
A system with decades of domain knowledge and hundreds of live installations is a foundation, not a liability. Throwing it out discards the most expensive thing you own — thirty years of encoded know-how.
Old and new run side by side
The strangler fig: new add-ons take over one workflow at a time while the legacy system keeps serving the rest. The same function can live in both during the transition, so there is never a cut-over moment.
Add-ons shaped around one person's job
A phone for the warehouse person scanning barcodes, a tablet with big buttons for point of sale, a dense screen for finance — instead of one interface forced to serve everyone.
Specifications before code
With AI the code is the cheap part; deciding what to build is not. We reverse-engineer validated specifications out of the legacy source first — generate, review, regenerate — which is where AI actually pays off on a migration.
Keep your team's skills and your customers' configuration
We choose paths that reuse the code and skills you already have — for a .NET shop that usually means staying in C# with Blazor Hybrid and .NET MAUI. Backward compatibility is a hard constraint, not a nice-to-have.
Cloud as a premium option, not a mandate
Web and mobile do not require the cloud. Customers who want it pay for it, on-premise customers keep what they have — so modernization opens a revenue line instead of reading as a migration tax.
Value in months, not a multi-year death march.
- Week 1
Design sprint
Map the personas, brainstorm the add-ons that would serve them, prioritise, and validate with real customers — before anyone commits to build.
- ~1 month
Clickable prototype
The highest-value, highest-pain workflow, made real. Stakeholders are convinced by seeing it, not by a deck.
- 3–4 months
A beta you can sell
A minimum marketable product: demonstrable, billable, and in front of customers while the rest of the system carries on untouched.
- 9 months max
In production
Every add-on is time-boxed. We don't take on initiatives that disappear into development for two or three years before anyone sees value — those are the modernizations that fail.
We have done this on a live system.
A 30-year-old core system, modernized without downtime
And before any of it was funded: in a day-and-a-half hackathon we rebuilt the core of a single screen whose logic was spread across three legacy layers, AI-assisted at every step. The point wasn't the screen — it was showing the client, in days, that the migration was real and achievable.
Client work is confidential; described here in general terms. See all three engagements — or the two people who would do the work.
