A Shopify partner for New York’s most demanding brands
New York sets the pace in retail, media, and DTC, and those brands need commerce engineered to match. SDG has partnered with Shopify since 2006 and works with enterprise brands across New York, bringing Platinum-tier engineering to replatforms, headless builds, and complex integrations.
The team brought in for the hard builds
We are senior engineers, not a generalist studio: the team called in when a build is too large or too consequential to risk. We embed with New York brands and their teams to ship work that has to be flawless. Explore our case studies or our Shopify Plus agency practice.
