What YYT does
YYT (legally Yes Yes Tech LTD) is a London-based bespoke eCommerce development agency founded in 2014, operating with a team of 1-10 people. The firm designs and develops high-performance online stores for direct-to-consumer and B2B brands across the United Kingdom, United States, and continental Europe. Its customer portfolio spans jewellery (Kimaï, Cast Jewelry), beauty and wellness (Ever/Body, Apnée), snack subscription (Graze), industrial retail (Radwell), apparel (Jupiter, EBY, Bubble), and software (Aplos), mixing startup, mid-market, and enterprise engagements.
The agency's core offering is structured around six service lines: Shopify Development (including Shopify Plus and headless storefronts), Contentful Development, Software Development (custom apps, integrations, APIs), Headless Commerce and Progressive Web App builds, Swell Development, and Magento Development. Technical execution is based on a modern JavaScript stack (React, Node.js, Next.js, Gatsby) with cloud infrastructure on Netlify and AWS, and integrations spanning Klaviyo, Yotpo, Stamped, Gorgias, Klarna, and Skio. YYT has built a proprietary UI component library called Zebra to accelerate headless commerce delivery, and claims Lighthouse performance scores near-perfect from project inception versus typical Shopify themes scoring below 60%.
Revenue is generated entirely through project-based professional services engagements, with quote-based pricing (no publicly disclosed rates) and ongoing maintenance and support retainers. The go-to-market is direct engagement via the company website (yyt.dev), supported by content marketing through a blog covering AI tools, platform comparisons, headless commerce, and web performance, plus organic presence on LinkedIn, Twitter, Facebook, and Instagram. The firm shows no evidence of institutional investment, no parent company, and no disclosed funding rounds, operating as a founder-led private limited company registered in the United Kingdom.
