Off-the-Shelf Themes Were Built
to Sell Themes — Not Your Products.
Bloated Theme Killing Your PageSpeed
Premium themes ship with 60+ unused features and 40 render-blocking scripts. Every 100ms of extra load time costs you 1% in conversions — silently.
Looks Like Every Other Shopify Store
Prestige, Impulse, Dawn — your competitors run the same bones. Brand differentiation is impossible when you share architecture with 50,000 other stores.
Mobile Was Bolted On, Not Built In
Off-the-shelf themes scale desktop down to mobile. But 75% of your traffic is on a phone. There's a gap between 'responsive' and 'built mobile-first'.
10 Apps Doing What Code Should
$300/month in apps patching gaps that 4KB of custom Liquid handles permanently. Every app is another script, another failure point, another reason to bounce.
Every Edit Costs £800 & Two Weeks
Liquid spaghetti and conflicting sections that break on touch. You're not the owner of your store — you're a tenant, paying rent every time you need to change a headline.
Built for the Portfolio, Not the Revenue
Most devs build for Dribbble screenshots. We build to a single metric: revenue per visitor. The difference is measurable — and it shows in your conversion data.
A Complete Store Build. Done Right.
Not a theme install. Not a colour tweak. A ground-up custom Shopify build engineered for performance, conversion, and brand authority.
Custom Liquid Theme
Built from Dawn or scratch — every section purpose-built for your store. Zero off-the-shelf bloat.
That Works.
Sub-2s Load Guarantee
Critical CSS, lazy loading, script deferral. Nothing ships scoring under 90 on PageSpeed Insights.
Mobile-First Architecture
Designed at 375px first. Every interaction built for your 75% mobile audience.
Shopify Plus Checkout
Custom UI extensions, post-purchase upsells, branded order summaries — all within Plus compliance.
Editable Custom Sections
Reusable Liquid blocks your team manages from the Shopify customiser — no developer required.
CRO Baked In from Day One
Trust signals, urgency cues, and conversion patterns built into every page — not retrofitted after launch.
From Brief to Live Store.
A structured build process with zero guesswork. You approve every decision before a line of code is written.
Discovery & CRO Audit
We analyse your current store or top competitors — heatmaps, funnel data, session recordings. Every design decision is evidence-based, not gut-feel.
Week 1IA & Wireframes
Page hierarchy, navigation structure, and conversion flow mapped out and approved before design starts. Blueprint first, then build.
Week 1–2High-Fidelity Design
Every page, every breakpoint, every hover state. Full desktop and mobile designs in Figma with your brand applied — signed off before development starts.
Week 2–3Custom Liquid Dev
Clean, documented Liquid code. No theme hacks, no app dependencies for core functionality, no Frankenstein architecture you'll regret in 12 months.
Week 3–6QA, Speed & Launch
Cross-browser testing, mobile QA, PageSpeed audit, and a structured go-live checklist. We don't push live until it's genuinely ready.
Week 6–7A selection of our award-winning work.

Six Weeks.
Their best Black Friday on record. Same products. Same ad spend. A store that was actually built to convert.
Solawave was on Prestige — it looked premium, but it wasn't built for the complexity of their product education funnel or the volume of their paid traffic. Mobile was an afterthought. PageSpeed was 58. Cart abandonment was high.
We rebuilt from scratch: custom scroll-driven education sequences, redesigned collection architecture, and a mobile checkout purpose-built for their high-AOV audience.
Different store.
Theme Install vs. Custom Build.
