# Creative CX > Creative CX is a specialist experimentation consultancy that helps enterprises establish, run, scale — and eventually bring in-house — high-quality product experimentation, optimisation and personalisation programmes, so that every team can experiment everywhere. We are tool-agnostic, and were the first UK consultancy proficient in server-side experimentation, having onboarded 100+ teams. We work with enterprise teams across retail, travel and hospitality, financial services, media and telco. Experimentation is the practice of validating changes with controlled A/B and multivariate tests before rolling them out to customers. Creative CX's premise is that only 1 in 5 ideas add measurable value and 2 in 5 actively make things worse, so experimentation is the only reliable way to know which is which before customers ever feel it. Our offer spans three stages — Understand (research and discovery), Experiment (delivery), and Scale (organisational enablement, including building Centres of Excellence and training teams to run experimentation themselves). We also work at the intersection of AI and experimentation, summarised as "AI for Experimentation, Experimentation for AI": using AI (including agentic coding) to build bolder, more complex tests faster and to embed best practice as teams scale; and applying experimentation rigour to AI itself — validating AI features through controlled experiments, rolling out AI adoption as measured tests rather than a leap of faith, and offering Evals as a Service, an offline LLM quality-evaluation layer (golden datasets, LLM-as-a-Judge with human validation, statistical rigour on noisy eval scores) that pairs with online A/B testing to gate both the quality and the business value of AI features. ## Services - [How we work: Understand, Experiment, Scale](https://www.creative-cx.com/): Our three-stage offer.
