About us

Sigma is a leading specialist in user experience consulting and design, information management, and web technologies. We provide research, analysis, design, development and support services, with specific expertise in usability, accessibility, content and document management, websites, intranets and online applications.

We are part of the Sigma group, a 3000-strong IT services company based in Sweden and with offices throughout the world. The UK team is the centre of excellence in the group for user experience services.

We draw upon the capabilities of the Sigma group for many of our development and technology projects.


We’re a committed team of researchers, thinkers, practitioners and experts. We were one of the first agencies in the UK to truly live and breathe User Experience, and that expertise runs through all of our services.


Everything we do is driven by research and user engagement. Putting users at the heart of our solutions delivers better products and services to a happier audience. That’s what user experience means to us. Here we share some of our thoughts, news and opinions on developments in the UX and digital world.


We work with some great people. We engage their users to design, build and optimise great solutions together. Our clients are diverse, forward-thinking, user-centred and socially-responsible. This helps to make our work varied, innovative and highly rewarding.
