What We Do
We cover everything Shopify — from pixel-perfect themes to complex integrations.
Paid Media & Growth ★
We built your store — now we fill it. As a Shopify agency that owns both sides, we run Google, Meta and TikTok ads on top of the exact store we engineered, with GDPR-compliant server-side tracking and Meta CAPI that actually fire on Shopify. No agency finger-pointing when a campaign underperforms: the store and the ads answer to the same team.
Custom Shopify Apps
Off-the-shelf apps can only take you so far. We build custom Shopify apps that automate your workflows, extend the admin, and solve the problems no public app will — private apps and Shopify Plus scripts you actually own, built with Node and React against the Shopify GraphQL API.
Headless Commerce
For brands that want blazing speed and total design freedom, we build headless Shopify storefronts on Hydrogen & Oxygen — a decoupled front end that renders in a blink while checkout stays on Shopify's rock-solid infrastructure.
Performance Audit
A slow store leaks revenue on every visit. We audit Core Web Vitals, Lighthouse scores and render-blocking resources, then fix them — faster load, better rankings, higher conversion. We routinely take stores to a 100 PageSpeed score.
Loyalty & Retention
Acquisition is only half the job. We build the retention engine that maximises lifetime value — loyalty programs, subscription flows and post-purchase upsells, wired into Klaviyo and Recharge so every order compounds into the next.

Now let us fill it.
Most ad agencies send traffic to a store they cannot touch — then blame the store when it does not convert. We build the store AND run the ads on top of it: Google, Meta and TikTok, with server-side tracking that actually works on Shopify.
- Full-funnel — from ad click to checkout
- GDPR server-side tracking & Meta CAPI
- Transparent fees, €5k+ min. ad spend
