We deliver exceptional digital solutions and an improved user experience for all.

About us

Sigma is a leading specialist in user experience, from research and design to testing, development and optimisation. We take an inclusive approach to improve the usability and accessibility of digital products and services, including websites, intranets, mobile apps and software. We can help you kick start new ideas or improve what you already have.

We are part of the Sigma group, a 5000-strong IT services company based in Sweden and with offices throughout the world.


We’re a committed team of researchers, thinkers, practitioners and experts. We were one of the first agencies in the UK to 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.
