Your platform got you here. It won't get you there.
One focus.
One focus.
You're hitting the ceiling. Page speed is dragging. Every small change requires a dev ticket. Your checkout can't handle what your marketing team is throwing at it. And the thought of migrating - with all the SEO equity you've built, the integrations you rely on, the customers mid-journey - feels like open heart surgery.
We get it. We've done this 50+ times for commerce brands doing $5M to $100M+. The migration doesn't have to be the thing that breaks your business. Done right, it's the thing that unlocks the next stage.
We design, engineer, and maintain commerce infrastructure for brands that have found product-market fit and are ready to scale. From conversion-focused UX to headless architecture on Hydrogen, our work spans the full spectrum of what Shopify Plus can do.
We work best with brands doing $5M-$100M+ in annual revenue. Brands that care about how their platform performs, not just how it looks. If you're building a category leader, we should talk.

Our migration process. No surprises.
We map your current stack, scope a fixed-price build, build alongside your live site, launch in stages, and deliver a post-launch roadmap.
Architecture Audit
We map your current stack - every integration, every data flow, every dependency. We identify what stays, what goes, and what gets rebuilt. You get a clear picture before a single line of code is written.
Fixed-Price Build
A scoped Phase 1 build with a fixed price. You know exactly what you're paying and exactly what you're getting. No scope creep. No surprise invoices.
Parallel Build + SEO Preservation
We build the new stack alongside your live site. Full 301 redirect mapping. Schema migration. URL structure preservation. Your organic traffic doesn't skip a beat.
UX architecture built around how your customers actually shop. Conversion-optimised layouts. Responsive design systems that look sharp on every device. Checkout flow engineering that reduces drop-off and increases average order value.
Advanced Engineering
Custom Shopify Plus builds, headless commerce on Hydrogen with Sanity and Algolia, complex third-party integrations, platform migrations from Magento, WooCommerce, and BigCommerce. Performance engineering that keeps your site fast under load.
Platform Partnerships
Ongoing retainers for feature development, integration maintenance, conversion testing, and strategic upgrades. Your platform evolves alongside your business. We stay close and keep things moving forward.

A stack built for the next five years, not the last five.When liquid isn't enough.
We build on Hydrogen + Sanity + Algolia. Sub-second page loads. Content that your marketing team can actually edit. Search that works the way your customers think. And a headless architecture that means your frontend and backend can evolve independently - no more "we need to rebuild the whole thing."
This isn't a stack we picked because it's trendy. It's the stack our CTO validated as the most future-proof for $5M-$100M+ commerce brands. It plays well with AI tooling, scales with your catalog, and doesn't lock you into a single vendor's roadmap.
Our headless stack runs on Hydrogen , Sanity , and Algolia . This combination delivers sub-second page loads, total design freedom, and a content workflow that marketing teams can actually use without developer support.
We've delivered headless builds for brands like Carwyn Cellars, Lo & Co Interiors, Coffee Company, and Projecta. Each project required a different approach to content architecture, product discovery, and checkout integration. The stack stayed the same. The implementation was bespoke every time.

Frequently Asked Questions
If you have more questions, we're happy to answer them - just reach out.
What if we lose our Google rankings?
Full 301 redirect mapping. Schema migration. URL structure audit. We've never had a client lose meaningful organic traffic post-migration.
What if something breaks on launch day?
Staged rollout with rollback capability. We monitor in real-time across time zones (Melbourne, LA, London). If something goes wrong, we catch it before your customers do.
What if it costs more than quoted?
Fixed-price Phase 1. The scope is locked before we start. If something comes up that's outside scope, we discuss it - you decide whether to add it or defer it.
How long will this take?
Typical Phase 1 builds run 8-12 weeks depending on complexity. We'll give you a timeline in the discovery call and we stick to it.
What do you migrate to?
Hydrogen + Sanity + Algolia as the core stack. Sub-second page loads, content your marketing team can edit without dev support, and search that works the way your customers think. We've validated this as the most future-proof stack for $5M-$100M+ commerce brands.
What happens after launch?
You get a prioritized roadmap of what comes next - delivered via async weekly sprints. Tuesday kickoff. Friday delivery via Loom. Your call on what gets built. Most of our client relationships extend well beyond launch.
