From £25,000
A full production system that scales and survives real customers. Accounts, billing, AI, search, security, dashboards — built to a standard most agencies can't match, because we built the engine that enforces it.
What you get
Every capability a production SaaS or internal platform needs, delivered as one system — not a menu you pick from.
Organisations, roles, invitations, member management. Per-row security enforced at the database, not just hidden in the UI.
Stripe with real webhooks, dunning, grace periods, refunds and a billing portal — not a Checkout redirect.
Chat with history, agents with tool permissions, RAG over your data. Eval gates in CI so quality regressions fail the build.
Eight security patterns on every table and action. An automated pentest suite runs on every deploy.
How it runs
The same four stages run every engagement. The service decides the scale, not the method.
01
Planner
One scoping call, then a written brief. Load-bearing pieces named, failure modes mapped. Two weeks.
02
Hub
Schema, security boundary and integration contracts on the page before a line is written. You sign off.
Pricing
Multi-tenant accounts, billing, AI features, hybrid search, admin dashboards, integrations, eight security patterns.

The full system: multi-tenant accounts, Stripe billing with real webhooks and dunning, AI features with cost dashboards and eval gates, semantic and keyword search, job queues, realtime subscriptions, admin dashboards, structured audit logs. Eight security patterns enforced on every table and action — not bolted on after launch.
Two weeks discovery, two weeks architecture, twelve to twenty weeks production build depending on scope. The timeline is defined 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.
Where we work
The service covers the whole of the UK, remote-first. Looking for an AI development company near Leeds? The local pages cover on-site availability and area-specific context.

Not sure of the shape yet? A Build Blueprint (£8,000) scopes and de-risks it with you before you commit to a build.

Eight security patterns 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, 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 produce a written report and 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.
