We build software we'd trust ourselves.
Zinteli is a UK software house. We make our own products and we build for clients, and the standard is the same for both: software that people can depend on, that keeps their data safe and that stays easy to change.
Product-led, by design.
Most agencies only build for others. We also build for ourselves, and live with the consequences in production.
That's why our products share an architecture in which the hard, easy-to-get-wrong decisions are made once and enforced by the build: UTC time everywhere, GUID v7 keys, offline-first sync, encrypted local storage, warnings treated as errors, and layering rules the test suite fails on.
When you work with us, your project starts from that foundation rather than a blank page.
Principles we don't compromise on.
People first
Software exists for the people who use it. We test with them early and often, and design for everyone, including people who use assistive technology.
Privacy is not optional
We collect only what's needed, protect it properly, and say plainly what we do with it.
Craft that lasts
Clear architecture, tested code and recorded decisions, so the next person can change it with confidence.
Straight talking
Honest estimates, early warnings and no jargon. If something isn't a good idea, we'll say so.
