Trusted by brands that define their categories
A Shopify partner for the Bay Area’s most technical brands
San Francisco and the Bay Area set the bar for engineering, and the brands here expect a partner who can meet it. SDG has partnered with Shopify since 2006 and keeps a team in San Francisco, bringing Platinum-tier engineering to replatforms, headless builds, and complex integrations for technically demanding companies.
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 Bay Area brands and their product and engineering teams to ship work that has to be flawless. Explore our case studies or our Shopify Plus agency practice.
