About
An agency that operates
what it builds.
Crestify is a UK engineering agency. We design, build and run production software: for companies with something to build, and for agencies that need delivery capacity under their own brand.
We also build and operate a portfolio of our own products. Running software in production, with real users and real costs, is where our delivery habits come from.

How we build
01
Fail loudly
Systems we ship tell you when something is wrong instead of pretending it is fine. A failure you hear about gets fixed the same day; one that stays quiet costs you customers first.
02
Built to recover
Things break: providers time out, networks drop. Systems we build pick up where they left off instead of starting over, so a hiccup never turns into a bill or a lost night of output.
03
Correct by design
The rules that keep your data right live inside the system itself, not in documents people forget to read. That is how things stay correct as teams and codebases grow.
04
AI that tells the truth
AI features we ship show where every answer came from and say so plainly when they do not know, rather than making something up. That is the difference between a demo and a tool your staff can rely on.
The record
The products →01
Products, operated
Six products built and operated in production, including an AI video platform that has run unattended for over two years and a decentralized live streaming service.
02
Enterprise delivery
A support assistant for Gala Games answering 200+ staff questions a day, every answer backed by the company document it came from. Lecture streaming used by 50+ schools.
03
Infrastructure
A live streaming platform moved to a server fleet 90% smaller, with every database verified along the way. No downtime, no data lost, dramatically lower running costs.
