YYT is an eCommerce tech consultancy based in London. Our developers have spent 15 years building and running the technology behind DTC and B2B brands.
2014—2020
YYT started in 2014, with Jonathan working as a developer and technical lead inside large-scale eCommerce businesses, seeing what brands need from their technology partners.
2020—2025
We built the agency to make an impact where it counts: a modern stack, senior developers, and one team that stays with a brand as it scales, on fair commercial terms. Over five years YYT built and scaled storefronts for 70 brands, DTC and B2B, across the US, UK and Europe. A pattern emerged: clients hired us for a build, then kept us for everything after.
2025—present
The engagements that worked best weren't projects. They were partnerships. So we made the shift official. YYT today is an eCommerce tech consultancy: senior developers and technical leads working as part of your team, bringing a startup approach to brands operating at scale.
Every person at YYT is a senior developer or technical lead. No junior bench, no account layer — when you work with YYT, you work with the people building your stack.
