Featured work

• Kimai

  Custom Shopify build for Kimai, an ethical lab-grown diamond jewelry brand. We developed a storefront with multi-currency sites for the US, UK, and Europe. Main features include SEO optimized collection pages per gold color, and a bespoke experience for engagement rings. We have supported Kimai throughout their growth, scaling from online-only to opening retail stores in London, LA, and Paris.

• Jupiter

  Custom Shopify Plus build for Jupiter, a US DTC haircare brand. We designed and developed a bespoke storefront with the following features and apps: subscriptions (Skio), reviews (Stamped), marketing automations (Klaviyo), and SEO optimization. We helped Jupiter scale online with data tracking, attribution, and CRO, before expanding to nationwide retail.

• EBY

  Shopify Plus redesign and development for EBY, a modern NYC underwear and subscription brand. Alongside their design and development team, we built dynamic landing page templates, product bundles, a loyalty program (Smile), and advanced subscription logic (Recharge) with checkout customizations, helping the brand scale its DTC subscription model.

• Irene Forte

  Shopify Plus redesign and development for Irene Forte, a luxury skincare brand. We delivered UX/UI improvements across their international websites, designed a custom skincare quiz to guide product discovery, developed high-converting landing pages, and implemented various marketing promotions.

• Bubble

  Shopify development and optimization for Bubble, a fast-growing teen skincare brand. We focused on theme optimization, page-speed improvements driven by performance reports, conversion rate optimization, and landing page development—and strengthened technical SEO to support growth.

• Perpète

  Custom Shopify theme design and development for Perpète, a French sustainable kids' fashion brand built on a circular model - customers can return clothes once they are outgrown. We customized and developed a bespoke theme to bring the brand's eco-conscious identity to life and support its DTC growth.

Ratings and reviews

• KimaiStore build or redesignSep 30, 2026

  Jonathan and the YYT team have been with Kimai since the very beginning in 2020, and they've been a true partner every step of the way. They built our site when Kimai was just starting out and have grown with us since. He's quick, thoughtful and a genuine pleasure to work with. Whatever we bring him, from routing and redirects across our UK, EU and French sites to the custom tools we use to run stock and reporting across our stores, he takes the time to understand what we're trying to achieve rather than just ticking off a ticket. For a brand like ours, where the website has to feel as considered as the jewellery, that care makes all the difference. Six years on, we couldn't recommend Jonathan and YYT more highly. Thank you, Jonathan!
