Build what others can't.
When the world's most recognized brands need commerce engineered at a scale and complexity others won't attempt, they hire SDG.
No one has built more, for longer, at this altitude.
Three advantages earned across two decades and hundreds of launches for some of the most demanding brands in the world.
The longest tenure on Shopify
We've been a Shopify partner since 2006, the year the platform began. Two decades of architectural decisions, edge cases and platform evolution are encoded in how we build. Tenure like this can't be hired, acquired or shortcut.
The deepest enterprise track record
Apple. Netflix. Barnes & Noble. Gap. Mattel. The builds that define enterprise commerce are the ones we're known for: vast catalogs, mission-critical integrations, unforgiving traffic. We take on the work most agencies decline.
Engineering mastery, end to end
We are not a generalist agency with a development department. We are senior engineers, the team brought in when a build is too large, too complex or too consequential to risk. The people who architect your platform are the people who ship it.
Trusted by the names shaping Canadian commerce.
We work directly with Shopify, Indigo, and Browns Shoes. Different businesses. Different briefs. The same senior engineering team behind the build.

Our business is, and always has been, referral-driven. We don't staff a sales floor and we won't pitch scope you don't need. We earn the next enterprise by being indispensable on this one. Learn more about our Shopify agency practice.
Master the complexity
We begin where others stall: mapping the systems, scale and failure modes that make enterprise builds genuinely hard.
Architect for scale
Every decision is made with two decades of platform depth, engineered to hold under real enterprise load.
Senior hands only
No hand-offs to juniors. The engineers who scope your platform are the engineers who build it.
Accountable for the long run
We stay engaged well past launch. Most of our clients have been with us for years.
The most recognized names in commerce — and the partner they keep.
Bring us your most complex build.
A replatform that can't slip. A catalog no one else will touch. An enterprise build that simply has to be flawless. That's the work we live for.
