Software we build and run ourselves
Alongside client work, RDZZ LTD builds its own products for UK property, housing, schools and families. Each one does one narrow job, and shows its working.
Had an invoice or an email from RDZZ LTD? It will be about one of these. Each product has its own terms, privacy notice and contact address on its own site.

Opening soonHow we build them
The same habits we bring to client work
- One narrow jobEach product does one thing a small organisation has to get right, and nothing else.
- Rules written down and testedThe rules that matter, such as legal dates, formulas and thresholds, are code with tests, not guesses.
- Show the workingFigures come with how they were worked out, so the person relying on them can check.
- Weeks, not quartersSmall, senior and quick: the way we'd want our own clients' builds to run.
