Production AI, assembled in weeks
The same four building blocks sit under every engagement we ship: a pipeline you can rebuild, an evaluation suite that gates it, instrumentation that proves it, and guardrails that keep it honest.
Explore all capabilitiesIngestion, chunking, embeddings and indexes built as versioned pipelines you can rebuild from scratch on any day of the week.

The platform
Everything you need to run AI in production
The unglamorous half of the work — the half that decides whether a model survives contact with real users, real data and a real audit.
Explore the platform workGrounded retrieval
Chunking, hybrid search and reranking tuned against your corpus rather than a demo set, with citations the business can check.
Data residency
UK and UAE regions, tenant isolation, and a documented path for every field that leaves your estate.
Evaluation harness
Golden sets and nightly suites that gate a release before a customer ever sees it. A regression fails the build, not the quarter.
Model version management
Pinned versions, shadow traffic and one-command rollback for the week a vendor ships a surprise.
Cost and latency budgets
Per-feature ceilings enforced at the gateway, with alerts that arrive before the invoice does.
Human in the loop
Review queues, approval thresholds and the audit trail your regulator will ask for.
Incident response, rehearsed
Runbooks, on-call rotation and a rollback drill run before go-live — because the first outage should not be the first time anyone reads the plan.
Private deployment
Your cloud, your keys, your network. We deploy into the estate you already audit.
Engagement
Everything a delivery partnership needs
Four phases, one rhythm, and a working agreement that survives the week something goes wrong. Most engagements reach a live, measured system in about twenty-two weeks.
How we workPartner-led teams
Every engagement is led by a partner who still writes code. No account layer between you and the people building the thing.
Progress you can open
Scope, spend and risk on a board you can check any day of the week, rather than a slide deck that arrives once a month.
Decisions written down
Every architectural call recorded with its trade-off, so the team that inherits the system inherits reasoning, not folklore.

- ADR-015Rerank on CPU, not the model provider
- ADR-016Human review above £5k exposure

Deliverable — AI Readiness Report + Prioritised Initiative Backlog
Strategise & Design
Our architects and AI researchers design the technical solution: model selection, data pipeline architecture, integration blueprints, and a phased delivery roadmap with measurable KPIs agreed upfront.
Deliverable — Technical Design Blueprint + Delivery Roadmap
Build & Implement
Iterative sprints with full transparency — weekly demos, live staging environments, and shared project dashboards. Rigorous code review, automated testing, and security-first standards throughout.
Deliverable — Production-Ready AI System
Launch & Optimise
Deployment is the beginning, not the end. We monitor model performance, track KPIs, retrain models as data evolves, and continuously improve your solution as your embedded AI team.
Deliverable — Ongoing Optimisation + Performance Reports
Observability
Instrumented from
the first deployment
Latency, cost, drift and groundedness are measured from day one, not bolted on after something breaks. You see what the model is doing, what it costs, and where it is getting worse.
Here is what you get out of the box:
- See spend per feature, per model, per day
- Catch drift before a customer reports it
- Prove groundedness with a citation trail
- Roll back a model version in one command
- Model calls
- 1.24M+12.4%

The difference
Why leading organisations choose Nixxie
Twenty-one years of shipping software, five of them spent making machine learning survive contact with production.
Read the case studies25+ Years of Deep Engineering Expertise
Built complex software systems since 2000. We have seen every technology wave and understand which patterns endure. This maturity means better architectural decisions and fewer costly mistakes.
Genuinely AI-Native, Not AI-Washed
We employ AI researchers and ML engineers, not just prompt engineers. Our solutions are architecturally sound and built for production reality — not retrofitted for a pitch deck.
End-to-End Ownership
We own the entire journey — discovery, design, engineering, deployment, and ongoing optimisation — under one roof, with one accountable team. No handoffs, no gaps.
Transparent, Collaborative Partnership
Shared dashboards, regular discovery calls, documented decision logs, and direct access to the engineers building your system. We treat your business objectives as our own.

The practice
An AI engineering practice with two homes and one standard.
We opened our first studio in London in 2004 — a small group of engineers building software for clients who needed it to actually work. Twenty-one years later we are forty-eight people across two studios, organised into three practices: AI & Intelligence, Product Engineering, and Strategy. Every engagement is led by a partner.

Senior practitioners. No middlemen.
Julian R. Mountford
Founder & Chairman

Undefeated on the golf course. Liverpool red through and through. Happy to let AI handle everything else — and partial to cats, but only the calm ones.
Graham Head
CEO
London
Watford FC loyalist and a systems engineer at heart. Does his best work at 35,000 feet — on the cloud, from the clouds. At least until turbulence files a bug report.
