Premium web apps, built in weeks.
Celium designs and builds polished apps, client platforms and internal tools, and helps businesses put AI to work properly. A working prototype in two to three weeks, live a few weeks later.
Products people actually enjoy using
For your clients and for your own team. Considered design, built properly, and made to be fast, secure and easy to run.
Client platforms and portals
Private, branded spaces for your clients: showcases, directories, enquiries and introductions. White-labelled for partners when you need it.
Customer apps
Mobile-first web apps people can save to their home screen, with no download. App Store and Google Play apps when they're worth it.
Internal tools
Dashboards, portals and workflows your own team uses every day. Replace the spreadsheets and copy-paste with something built around how you actually work.
AI, where it helps
Search that understands plain English, requests turned into clear briefs, assistants that know your content. Built in, not bolted on.
Three stages, each priced up front
You see a working product early, and you decide whether to carry on after the prototype. No long specifications, no surprises.
Prototype
2 to 3 weeksA working version in your brand, with your real content. Something you can put in front of customers or partners before committing to more.
Build
4 to 6 weeksThe production platform: security, data protection, admin tools for your team, testing across devices, and hosting.
Care
MonthlyHosting, monitoring, fixes and improvements for a fixed monthly fee, so the product keeps getting better.
Recent products
Designed and built end to end, and in the hands of real users.
The Vanguard
A private client platform for a collective of respected design, delivery and lifestyle brands. Clients describe what they need, by text or voice, and AI search recommends the right members, with an introduction in a couple of taps.
- Under a week
- From brief to working prototype
- Text or voice
- AI search in plain English
Pal: Your Health Coach
A nutrition and health coaching app with an AI coach you can message or talk to, and plans that adapt to your week. The latest version was designed and built solo.
- 38,000+
- AI runs in production
- Voice and chat
- A coach that checks in
This is exactly what we wanted. Chris turned our brief into a working platform in days, and it feels completely on brand. Clients simply describe what they're looking for and the right members come straight back.
Studio quality, without the studio overhead
Product, commercial and technical
One person who shapes the product, keeps it commercially sensible and builds it, so nothing gets lost between a product manager, a designer and a developer.
Weeks, not months
I work with the latest AI development tools, which is how a polished product arrives this quickly.
Fixed prices
Each stage is priced before it starts. You always know what you're paying for.
Put AI to work where it pays
Not sure where AI fits in your business? I help you find where it genuinely saves time or wins work, then design and build it properly, from a focused review to systems running in production.
Talk about AII'm Chris Davison, a product engineer. I come from product, I think commercially, and I build everything myself: design and UX, front end, back end, and AI that runs in production at scale across web and mobile.
I started on the commercial side, at GSK and then delivering £100m+ programmes at Turner & Townsend, before founding Hawkr, an AI computer-vision advertising platform used by Johnson & Johnson, Shell and Sodexo. Since then I've worked in product and technology strategy for AI companies, including Mind Foundry, the Oxford University spin-out, shaping what gets built as well as how it's built.
I'm also a hands-on engineer. I founded Pal, an AI health coach on the App Store with more than 38,000 AI runs in production. I've architected AI systems that run in production for businesses across the UK.
Most projects are split between a product manager, a designer, developers and someone watching the budget. Celium puts all of that in one person, so what gets built makes commercial sense, is engineered properly and reaches people quickly. The name comes from mycelium, the network under the forest floor that quietly connects everything above it. I'm based in Newcastle and work with clients across the UK.
