The studio
Founded in London in 2004 and expanded to Dubai in 2021, Nixxie International is a senior AI engineering studio. We work with founders, operators and boards on the systems that will define the next decade of their business — the infrastructure, the models, the products, and the culture to use them well.
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.

Observability
Every system we ship arrives already instrumented.
Latency, cost, drift and groundedness are measured from the first deployment — not bolted on after something breaks. You see what the model is doing, what it costs, and where it is getting worse.

Julian R. Mountford
Founder & Chairman
Dubai
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.
Engagement
A structured path from problem to production.
Four phases, one rhythm. Most engagements reach a live, measured system in about twenty-two weeks.
Discover & Analyse
Deep-dive workshops with your stakeholders to map workflows, identify pain points, assess data maturity, and quantify the ROI opportunity for AI.
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.
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.
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.

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.
