Hex is a specialist Sanity CMS agency in London, building brands, headless websites and AI fact layer foundations.
This is what context looks like
Every answer comes from Hex’s own facts, in one place we own. Your organisation could answer the same way.
An AI advisor built on Hex’s own published facts. Conversations are stored for 90 days so we can improve it; no account is created. If you ask us to follow up, we keep your confirmed email and a summary of the conversation. Email hello@hexdigital.com to have either deleted.
What we build on
“From strategic leadership, to a new design system with a full technical implementation across multiple countries, Hex have been truly amazing from start to finish.”

Our customers
Our intelligent growth system
With your knowledge in one place, we can see clearly where you stand today.
Insight shows the gap. Strategy sets the direction and priorities to close it.
A clear direction shapes how your organisation looks, sounds and feels.
Your brand comes to life across your website, products and every touchpoint.
Great experiences need an audience. We take them to market and measure what works.
Every result feeds back into your knowledge, so the system gets sharper with each cycle.
Our solutions
Each one brings research, design and engineering from one team, with the knowledge layer built alongside it.
Your AI is already talking about you. The question is whether it’s right. A fact layer puts your team back in charge of the truth: one approved source that every agent, app and person draws from. Change a fact once. It’s correct everywhere.
Moving off a legacy CMS shouldn't mean losing years of content or momentum. We plan and run the migration to Sanity end to end, from content modelling through to launch, so your team comes out the other side with a faster site and a platform built to grow.
Great brands shouldn’t need a gatekeeper. A design system gives your team everything they need to build on-brand, at speed, without starting from scratch. We hand over the keys. You keep the momentum.
Growth rarely comes from one channel working harder. We map and build across nine connected pillars, from website and content to CRM, brand and intelligence, so every part of the ecosystem pulls in the same direction.
Your website shouldn’t hold your business back. Headless and composable architecture separates your content from your code, so you can choose the best tools for each job and swap them out as you grow. Faster sites. Freer teams. A platform built for whatever comes next.
A brand and a digital estate apart over time. This programme brings them back in step with renewed energy: refreshed identity, message and visual system, carried through into a digital presence that reflects where the organisation is now.
