Who we are
“The people who design your product are the same people who build it. No account managers, no translations, no gaps.”
We have built a national digital identity system, NHS patient platforms, and the website for the Royal Astronomical Society — a learned society founded in 1820. The work is serious. The clients trust us because we stay.
Founded in 2003, based in London. Designers and engineers work as one team — no handoffs, no account managers, no gaps between the people who make decisions and the people who write the code.
Yonescat started in 2003 with one idea: design and engineering should work as one team, not hand things over a wall at the end of a project. Twenty-two years later, that is still how we work.
The work includes a national digital identity system for Iraq, the Royal Astronomical Society's website, NHS patient platforms reaching tens of thousands of people a month, and over ten European Commission-funded programmes spanning 20 countries. We have also built charity apps in daily use by children with disabilities in West London.
We are a social enterprise, built around relationships rather than transactions. Transparent pricing, honest timelines, and the same team throughout — because that is how trust actually forms.

Est. 2003
London-based studio
Three things we don't compromise on.
Impact before aesthetics
We measure success by outcomes for real people, not awards or accolades.
Radical transparency
No agency mystique. Transparent pricing, clear timelines, honest conversations about what we can and cannot do.
Long-term partnership
We build relationships, not projects. Most of our clients have been with us for years.
Heman Yones
Founder & Director
Heman founded Yonescat in 2003 after graduating from Brunel University. A Kurdish-born British entrepreneur, he has spent over two decades building digital products at the intersection of design, engineering, and civic impact — from NHS platforms to iQiD, a national digital identity system he led the development of. He also serves on the board of the MEED Foundation and as CEO of iQ Labs.
Organisations that need a partner, not a supplier.
NHS & Healthcare
Patient-facing platforms designed to NHS guidelines. The Circulation Foundation website reaches 60–80 thousand people a month.
Learned Societies & Institutions
We built the Royal Astronomical Society's website — an institution founded in 1820, appointed by Council resolution after competitive tender.
National Digital Infrastructure
iQiD is a national digital identity platform for Iraq — biometric authentication, single sign-on, government services, and bill payments for millions of citizens.
Charities & Social Sector
The Log Cabin (Mayor of Ealing), St Michael's Fellowship, and organisations across the UK social sector. Apps and platforms in daily use.
European Institutions
Over ten European Commission-funded projects across 20+ countries — Daphne III, Lifelong Learning, Youth in Action programmes.
