Bespoke software,built with the disciplinethat runs banks.

We bring that discipline to your business: web apps, spreadsheets rebuilt as real software, and practical AI, self-hosted on UK infrastructure if you want it.

What we do best

What we build,rescue and run.

Everything we take on sits in one of three lanes: we build new software, rescue what's struggling, and run what you'd rather not host yourself. These are the engagements two decades of production work have made us genuinely good at, not a list of everything we'd say yes to.

Build

Web apps

Customer portals, internal tools and dashboards, built to be fast, accessible, and still maintainable years from now.

ReactNext.jsTypeScript
Build

Mobile apps

Cross-platform iOS and Android products that feel native, from one codebase your team can keep moving.

Spreadsheet to software

The critical spreadsheet running half your business, turned into a real app, with permissions, history and no broken formulas.

Excel → web app
Rescue

Legacy rescue & rewrites

Inherited a system nobody understands, or an API-backed app that has grown brittle? We stabilise it, document it and modernise it, no risky big-bang rewrite.

Rescue

AI integration & rescue

LLM workflows and automation built into daily operations. Already rolled out AI that isn't quite working? We turn stalled pilots into production systems.
