The problem

Your dev team's three options usually all suck.

When your roadmap outgrows what a theme app can do, you're in our territory.

×Cheap freelancer: ships fast, breaks faster, leaves you with unmaintainable spaghetti Liquid.
×Big-box agency: 8-week kickoff, junior devs, and a six-figure invoice for a theme tweak.
×In-house: takes 4 months to hire a senior Shopify dev, who'll leave in 11 months.
×Meanwhile your roadmap gathers dust and your CR/AOV stays flat.
What you get

Everything you need.

Engineering the top tier of Shopify — Liquid, Hydrogen, headless, and custom apps. Built and shipped by senior operators — not a junior team you didn't meet on the sales call.

We migrated 14k SKUs and a custom B2B portal to Plus in 11 weeks with zero downtime. Their senior team is the cleanest Liquid I've ever read.

FAQ

The fine print.

Still got questions? Book a 30-minute strategy call — we answer everything and there's no commitment.

Liquid or headless?

Honestly? 80% of brands should stay on Liquid until they have a real reason not to. We'll tell you the truth in the architect call.

Do you work with our existing dev team?

Yes. Embedded squads, code reviews, paired engineering. We integrate with your Linear, Slack, GitHub.

What about ongoing work after launch?

Retainers from $8k/mo for ongoing roadmap, performance, and incident response.

Do you do checkout extensions / Functions?

Yes — Functions in Rust, checkout UI extensions in React. We've shipped 30+ to production.
