Mutex Systems builds production AI systems — AI applications, agentic systems that take real actions across multiple tools, LLM-powered features inside SaaS products, RAG-based knowledge systems, AI chatbots, and the secure platforms that let large enterprises adopt AI without losing control.
AI that does its job every time, for the people who depend on it, under the security and compliance your business demands. We treat AI engineering as an extension of software engineering — same discipline around testing, monitoring, and security, plus the extra rigour AI demands.

Fourteen Core Services
AI & Automation Across the Full Spectrum
We have organised our AI and automation work into fourteen clearly defined services so you can quickly identify what fits your situation. Each has its own process, technology stack, compliance posture, and deliverable set.
AI Application Development
SaaS features, internal tools, standalone AI products
End-to-end AI applications built around real workflows — from the user interface to model serving, with evaluation harnesses and observability built in.
AI agents that take real actions across multiple tools — researching, deciding, and acting — with human checkpoints, audit trails, and safe fallback paths.
Production LLM systems that stay reliable across frontier models — OpenAI, Anthropic Claude, Google Gemini, and self-hosted open-source on your own infrastructure.
Embedded AI features inside existing SaaS products
AI copilots embedded inside CRM, ERP, and SaaS interfaces — drafting, summarising, surfacing insights, and suggesting next actions without leaving the tool.
AI that turns raw data into written insights — automated weekly reports, anomaly detection, forecast narratives, and natural-language queries over your data.
Retrieval-augmented generation systems that answer questions from your document library — policies, contracts, manuals — with source citations and access controls.
Machine learning models trained on your data — demand forecasting, churn prediction, pricing optimisation, fraud detection, and operational anomaly detection.
AI systems designed with deliberate human checkpoints — confident actions proceed automatically, uncertain ones route to a human with full context pre-loaded.
Enterprise AI platforms built for regulated environments — role-based model access, PII controls, cost governance, EU AI Act mapping, and SOC 2-ready logging.
Role-based model access & PII redaction at ingestion
EU AI Act classification & NIST AI RMF alignment
Cost dashboards & circuit breakers per team / feature
Every Phase Delivers Working Software and Full Documentation
At the close of each phase you receive a complete bundle that lets your team verify the work and continue it without us if you ever choose to. Code, IP, and credentials are in your name from day one.
Operational runbook covering fallback paths and cost circuit breakers
Data flow diagrams and privacy impact assessment
Compliance evidence pack — ISO 27001, SOC 2, EU AI Act, NIST AI RMF
How We Engage on AI Work
From First Conversation to Live Production
AI engagements need a slightly different rhythm to traditional software — the uncertainty is higher early on, and the evaluation discipline matters more. We accommodate that with a structured model designed around managed risk and short feedback loops.
01
Discovery
Paid, fixed-fee work covering use-case definition, data feasibility, model benchmarking, and a written architectural recommendation.
02
Prototype & Evaluation
Focused build with a documented evaluation harness. Quality is measurable from day one rather than felt by intuition.
03
Production Engineering
Data pipelines, observability, cost controls, fallback paths, safety layers, and compliance evidence built alongside the model layer.
04
Rollout & Improve
Controlled rollout with feature flags and shadow mode for agents. Monthly quality reviews and quarterly model evaluations after go-live.
FAQs
Common Questions About AI & Automation
Straight answers about how we scope, price, build, and govern production AI systems.
What is the difference between AI, machine learning, and automation?
Automation is software that does the same thing every time, given the same inputs. Machine learning is software that learns patterns from data and applies them to new cases. AI is the broader category that includes machine learning, large language models, and other techniques that produce outputs that look intelligent. The right tool depends on the problem — repeatable workflows want automation, pattern recognition wants machine learning, language understanding and generation want LLMs. We pick by problem fit rather than by what is fashionable at the time of the engagement.
How much does an AI project cost?
Build costs typically range from twenty to a hundred thousand pounds for a focused production AI feature, and from one hundred and fifty thousand upwards for an enterprise platform. Ongoing model costs vary widely — from pennies per request for cheap-model use cases to several pounds per complex agentic workflow. We model expected ongoing costs during the discovery phase so the business case is clear before any significant investment is made.
How long does it take to build an AI feature?
A focused AI feature typically goes from kick-off to production in twelve to twenty weeks. The prototype usually arrives in four to six weeks, with the remaining time spent on production engineering, safety review, observability, and controlled rollout. Larger platforms move in phases over six to twelve months. Anyone promising a few weeks for a production-ready system is usually skipping the work that makes the system actually reliable.
How do you stop the AI from hallucinating?
Several controls in combination. Retrieval-augmented generation grounds the model in real source documents instead of relying on training memory. Structured outputs constrain what the model can return. Verification chains check claims against sources before they reach the user. Confidence thresholds escalate uncertain answers to humans. Clear UI signals tell the user when the system does not have the answer. Evaluation harnesses catch regressions before they reach production. No single control is perfect; the combination is reliable.
How do you handle data privacy and AI compliance?
Privacy and compliance are designed in from the first sprint rather than retrofitted at audit. Data classification drives model selection — sensitive data routes to providers and regions that satisfy your obligations, with self-hosted models available for the most sensitive cases. PII redaction happens before data leaves source systems where possible. Audit logs capture every model call. EU AI Act, GDPR, ISO/IEC 42001, NIST AI RMF, and sector-specific frameworks are mapped explicitly per project and evidenced throughout delivery.
Can you work with our existing AI investments?
Yes. Many engagements involve productionising an internal prototype, stabilising a vendor solution that is underperforming, or unifying fragmented AI experiments into a governed platform. We start with a written audit, deliver a stabilisation plan, and then move into improvement work. We work patiently with existing vendors where possible to keep continuity and avoid throwing away investments that have value.
Do you build AI for regulated industries?
Yes, and it is a significant portion of our AI work. We have shipped AI in banking, insurance, healthcare, and government settings — including under scrutiny from regulators such as the FCA, SBP, SECP, SAMA, and CBUAE. Regulator-friendly AI is not less innovative than consumer AI; it is more disciplined. We design for both innovation and compliance simultaneously, rather than treating them as trade-offs.
Should I wait for AI to mature before investing?
It depends on the use case. For high-stakes fully autonomous decisions, a measured approach is sensible. For productivity gains — drafting, summarising, search, classification, document processing — the technology is already production-ready and early movers are pulling ahead measurably. The best investments today combine current AI capability with proper engineering, so the system improves as the underlying models improve rather than needing a full rebuild each time.
