About Scalexa — Production AI Specialists
Why we started
Scalexa is an AI consultancy focused on the difficult gap between a promising model and a dependable production system.
Our work has supported large organisations including Mozilla, Coca-Cola and Fortune 500 enterprises. That experience shapes how we assess risk, define evidence and design systems for demanding operating environments.
Scalexa exists to remove the gap between AI ambition and production reality. We give direct answers about data readiness, model choice, evaluation, operating cost and whether AI is the right approach at all.
Much of the work that reaches us is already in a difficult place: an AI pilot that never made it to production, unreliable retrieval, weak evaluation or inference costs that break the business case. We are comfortable there.
How we work
Six commitments that shape every engagement, whether it's a two-week architecture diagnostic or an 18-month platform rebuild.
Diagnosis before delivery
We start with an architecture read, not a statement of work. If the honest answer is that you don't need us — or need less of us than you thought — we say so before anyone signs anything.
Weekly billing on actual hours
No retainers you have to grow into, no change-order theatre. You see what was worked on each week and you can stop, scale up, or scale down at any point.
We hand the keys back
Code, evaluation assets, documentation and runbooks ship with the work. Your organisation owns the AI system when we leave — no dependency built in on purpose.
We take the difficult work
Half-finished AI pilots, unreliable retrieval and models that fail outside a demo. The difficult production problems are the ones we are built for.
Built at a serious calibre
We bring Fortune 500 standards to every AI engagement.
Who you'll deal with
Gareth Slaven
Founder / Director
Runs delivery and client engagements and is usually the person on the other end of a first call.
Aurelien Duarte
Founder / Director
Leads engineering and sets the technical standard for production AI delivery.
What we cover
Deep in a handful of areas rather than shallow across everything. If a project sits outside these, we'll tell you and point you somewhere better.
