A Los Angeles Shopify agency since 2006
SDG (Spiegel Design Group) is a Los Angeles Shopify agency headquartered on San Vicente Blvd., and one of the longest-tenured Shopify partners anywhere, building on the platform since 2006. From our home in LA we have engineered commerce for some of the most recognized brands in the world, from national retailers to category-defining DTC labels.
Enterprise depth most LA agencies can’t match
We are a Shopify Platinum Partner, the platform’s highest tier, and a Shopify Build Award winner for our work on Glossier. The team that scopes your project is the senior team that builds it: no junior hand-offs, no learning on your budget. It’s the depth behind work like our Barnes & Noble replatform, brought to brands right here in Los Angeles.
Full-service Shopify for LA and California brands
As a full-service Los Angeles Shopify agency we cover the entire lifecycle: UX/UI design, theme and headless development, replatforming and migration, systems integration, SEO, CRO, accessibility, and ongoing support. We scope each engagement to the actual work, from a single feature to a multi-month enterprise build, for brands large and small. Explore our full Shopify services or our Shopify Plus practice.
Why work with a local Shopify agency
For LA and California brands, a local partner means real-time collaboration in your timezone, in-person working sessions when they matter, and a team accountable to its own backyard. The reach is anything but local, though: we deliver for enterprise clients nationally and internationally. Browse our case studies or see how we approach replatforming and migration.
