Shopify UX/UI Design That Converts
Design that looks the part and earns its keep. SDG pairs brand-led Shopify UX/UI with conversion-rate optimization, designed and built by the same senior team, so the storefront is beautiful, fast, and measurably better at selling.
Trusted by brands that define their categories
Design that sells, not just impresses
A storefront is a sales instrument. We design Shopify UX and UI around how people actually shop: clear hierarchy, frictionless paths to purchase, and merchandising that scales with a deep catalog, all in service of the brand rather than at the expense of it.
UX research and conversion-rate optimization
We back design decisions with evidence, from UX review and analytics to structured A/B testing and CRO. Award-winning work like our Glossier build shows what happens when distinctive design and relentless conversion focus are engineered together.
Design and engineering, one team
Because designers and senior engineers sit together, what gets designed is what gets built, pixel-accurate and performant, with accessibility built in. Explore our case studies or our Shopify Plus practice.
