ServiceAll services
Customer portals, internal systems and SaaS products, designed, built and handed over by one team, from £18,000 · typical project £30,000–£50,000.

What you get
Auth, a real data model and your core feature, deployed and monitored. Something to put in front of customers or investors.
Organisations, roles and invitations, with per-row security enforced at the database rather than hidden in the UI. Stripe with real webhooks, dunning and a billing portal.
Chat with history, agents with tool permissions, RAG over your data. Eval gates in CI so a quality regression fails the build.
Eight security patterns on every table and action, and an automated pentest suite on every deploy. In from the first commit, not bolted on before launch.
How it runs
The same stages run every engagement. The service decides the scale, not the method.
01Blueprint
One scoping call, then a written brief. Load-bearing pieces named, failure modes mapped.
02Blueprint
Schema, security boundary and integration contracts on the page before a line is written. You sign off.
03Forge
A weekly preview URL and readable diffs, with every security pattern enforced from day one.
04Forge
Deployed to your cloud, keys transferred, pentest run, runbook delivered. The first week of traffic is monitored.

A first version is auth, a real data model and your core feature: enough to learn from, and built so it grows rather than gets thrown away. A production platform is the full system: multi-tenant accounts, Stripe billing with real webhooks and dunning, AI features with cost dashboards and eval gates, search, job queues, realtime updates, admin dashboards and structured audit logs. Same foundations; the platform has more of them.
Start smaller whenever you can. Most people should: a first version teaches you what the platform needs to be. We'll say plainly if the cheaper tier is enough, even if it was the dearer one you asked about.
For a full platform: two weeks of discovery, two of architecture, then twelve to twenty weeks of build depending on scope. A first version is a shorter build. Either way the dates are fixed in the architecture phase, not guessed at kickoff.
You do. Your repo, your Vercel account, your Supabase project, your Stripe account, your keys. No Canarlo SaaS in the loop, no licence fees. The handover doc names every environment variable, every cron and every failure mode.
Eight security patterns are enforced by default on every table and action: Zod validation, auth checks, UUID validation, correct client scope, RLS-backed data isolation, structured error responses, MIME validation on uploads and clamped pagination. The platform includes its own automated pentest suite.
Yes. We start with an audit: a structured review of the existing codebase, security posture, data model and scalability profile, then a written report and a migration plan.
Real AI features: chat interfaces with history, autonomous agents with tool permissions and audit logs, RAG over your own data with source citations, AI-generated summaries. All with cost dashboards, eval gates in CI and circuit breakers.
Solutions this powers
A solution is a specialist build on top of this service. Each page shows the scope, price and questions for that kind of system.
Start smaller
Neither is a build. Each is a short, fixed look at your situation, and each leads into a Blueprint.
Areas we cover
The service covers the whole of the UK, remote-first. The local pages cover on-site availability and the sectors we know best in each place.
