I'm Stuart. I work with Government-agencies, large consulting firms and ambitious start ups on market-making products that tackle topics like net zero, healthcare inequalities and new medical therapies.
I have a human-factors background in large technology consultancy (PA Consulting Group), a further decade in Cambridge start ups and latterly in design leadership roles within the Innovate UK Catapult network.
I have a solid reputation helping firms exercise creative solutions whilst managing complex risk. I have helped numerous healthcare startups to achieve FDA, MHRA, CE and UKCA approvals in aggressive timescales. I am a seasoned ISO 13485/14971 and IEC 62304/62366 practitioner.
I can help your team navigate complex user-requirements and articulate the product or service attributes for commercial success.
Let’s do great work together.
Clients come to me to help define new product categories, plan bold service experiments and specify digital-products where user-safety can often be life-critical. If you need Serious UX, let's start some great work together.

Service blueprinting
Greenfield project or fledgeling digital service? Aware you need the user experience mapping but not got the method experience in your current teams? Make sure you don’t miss this opportunity to fully explore and define a friction-free UX across all the best user touchpoints.
I have a large body of experience working with diverse teams to produce both Journey Maps and Service Blueprints that form the single-point of truth for building complex new services.
