Crafted Chouette Sauvageonne's flagship on Shopify — editorial-grade, end to end.
A London-based luxury handbag and eau de parfum house wanted a flagship that read like an editorial spread, not an online store. We built a custom Shopify theme, hand-tuned the typography and grid for art-direction, and shipped a members' collection flow for their Insiders Circle.
Achieved by refactoring core Liquid logic, stripping bloated apps, and implementing critical-rendering-path optimisations.

A lean collective with enterprise standards.
For the past eight years our team has been building Shopify stores, custom web applications, and the tooling that surrounds them. Our work ranges from boutique candle shops to tax filing platforms — but the standard stays the same: thoughtful design, dependable code, and honest communication.
We operate as a lean, high-caliber collective of developers and designers. By eliminating account managers and layers of bureaucracy, our clients work directly with senior engineering talent to ship faster and more efficiently.
Services that actually ship.
We handle the full lifecycle — from first sketch to launch day to ongoing improvements. Pick a single service or have us take on the whole project end to end.
Shopify development
Custom Shopify stores built on solid Liquid foundations. Theme work, app integrations, payment setup, and the small details that separate a good store from a great one.
Web applications
Full-stack web apps using React, Next.js, and Node. Dashboards, internal tools, marketplaces — whatever you need to run your business better.
UI / UX design
Interfaces designed around how people actually use them. Wireframes, prototypes, and design systems your developers can actually build.
Theme development
Bespoke Shopify themes from the ground up. Fast, accessible, brand-driven, and easy for your team to maintain after we hand over.
SEO & growth
Technical SEO, content strategy, and the analytics setup to understand what's working. We focus on work that actually moves rankings.
Brand & graphics
Logos, marketing collateral, and the visual building blocks of your brand. Tight collaboration with our design lead from start to finish.
What you can expect from us.
The principles we work by — these aren't aspirational statements, they're the operating rules our clients hold us to.
Outcomes, not hours
We focus on shipping what moves your business — fewer meetings, more progress. Every milestone ties back to a measurable outcome.
Honest communication
We say no when an idea won't work, surface bad news early, and give you the kind of feedback you'd give yourself if you had the time.
Built for speed
Performance isn't an afterthought. Every store and app we build is optimised for Core Web Vitals, SEO, and real-world devices.
Quality you can edit
Clean, documented code your team can actually maintain. No vendor lock-in, no inscrutable magic — just craft you can build on.
A simple, no-surprises process.
We keep our process boring on purpose. Clear expectations, regular check-ins, and milestones you actually understand — so the work itself can be the surprise.
