OVERVIEW
One web development company for web, mobile and custom builds
Many buyers come to us looking for a website development company and find a software product development company instead. We plan, design and build web platforms, mobile apps and internal systems on PRISM OS, so every stage ends with a gate you sign. The engineers who build your prototype lead production, so nothing gets lost in a hand-off.

WHY SMARTX
Why SmartX for Software & Product Engineering
You own everything
All code, decision records and datasets are yours from day one, with a full IP handover at launch and no licence lock-in.
Same engineers throughout
The people who build your prototype lead production, so context, decisions and trade-offs never get lost between teams.
Web and mobile together
Hire one mobile app development company that also builds your web platform, so APIs, design system and release dates stay in one plan.
Evidence every fortnight
Fortnightly evidence reviews show working software against the signed scope, and UAT sign-off takes three clicks when each release is ready.
TOOLS WE USE
The stack, chosen per problem
ENGAGEMENT MODELS
Choose how we work together
Every model keeps the same signed gates, fixed milestones and full code ownership.
Gated delivery pod
A senior pod owns the outcome from Problem Brief to production, priced per gate so you can stop at any signature.
Dedicated engineers
Engineers who join your team and sprints, with PRISM briefs and evidence reviews added on top of your process.
PRISM OPS retainer
Hosting, security and a monthly improvement budget, run by the same engineers who built the system.

FAQ
Questions before you book
Not covered here? Ask on the call.
Do you build websites as well as web applications?
Yes. Our web development services cover marketing sites when they sit alongside a product, though most of our work is web applications, portals and platforms with real business logic. If you only need a brochure site, we will say so and suggest a better fit.
How much does a project cost?
Cost depends on scope, so we agree it in writing after the Discovery Sprint, once the Problem Brief and PRD-Lite are signed. Each gate has a fixed price you see before work starts, and the prototype gate ends with a clear go, reshape or stop decision.
Do you work with non-IT businesses?
Yes. Alongside IT companies we build for law firms, CA and audit practices, manufacturers and startups. We start with how your team works today and design software around it, so you can work with us without an in-house technical lead.
Who owns the code?
You do. All code, decision records and datasets belong to you, and launch includes a formal IP handover and a 60-day written bug-fix warranty. If you later move support to another team or in-house, they inherit a documented codebase and the reasoning behind it.
What happens after launch?
PRISM OPS takes over. Host keeps your product running on monitored infrastructure, Shield covers security and patching, and Evolve adds features through the same engineers who built it. You can also take support in-house at any point using the handover pack.
