AI Software Development, Built to a Verifiable Standard

A UK AI software development company that ships production AI-enabled SaaS — designed against the EU AI Act's requirements from the first line of code, governed, and engineered to be inherited.

What it is

AI software development is where most teams cut the corners that a security review finds first: ungoverned model access, no audit trail, and no way to say why the system behaves as it does. We build custom AI-enabled SaaS the same way we build any production system — modular architecture, least-privilege access, full audit logging — with the AI layer mapped against the EU AI Act and governed, not bolted on. The result is software your customers' security teams recognise and your next CTO can take over from the decision trail.

What’s included

Custom AI-enabled SaaS

Production systems built to a verifiable engineering standard, not a demo dressed up as a product.

EU AI Act alignment from day one

AI use mapped, risk-classified, and governed — designed against the Act's requirements from the first line of code.

Least-privilege model access + audit logging

Every AI action is access-controlled and logged, so behaviour is traceable and reviewable.

Modular, multi-tenant architecture

Domain-separated and audit-ready, with SAST/DAST and dependency scanning in CI.

The Governance Pack

Architecture Decision Record, Threat Model, Security Posture Document, Operational Runbook, and Forensic Handover — delivered with the build.

Where it fits

Regulated SaaS

AI-enabled portals for firms whose customers audit their suppliers — evidence and access logs generated by design.

AI Intake

Voice and chat agents that engage enquiries 24/7, qualify them, and book the meeting — governed and logged.

Knowledge

Turn internal docs and SOPs into an assistant your team can query, with citations and access control.

Questions, answered

We build AI into production systems to the same verifiable standard as everything else — OWASP ASVS Level 2, least-privilege access, and full audit logging — with the AI layer mapped against the EU AI Act and governed. It is engineered to survive a security review, not just to demo well.
We design against the EU AI Act's requirements from the first line of code: AI use is mapped and risk-classified, access is least-privilege and logged, and the reasoning is captured in the Architecture Decision Record and Security Posture Document that ship with the build.
Yes — 100% of the IP is assigned to you on payment, including code, configuration, prompts, and documentation. No lock-in, no dependency on us to keep it running.
Typical production engagements run £50,000–£150,000, invoiced per phase, with Stage 0 a fixed fee credited against the build. You approve each phase before you pay for it.
