Shopify studio for brands and agencies

We build and look after Shopify stores, and show you every change.

For brands, and for agencies under their own name. Every change comes with a before and after, and everything we’ve shipped is in the log below, with its date.

Recorded on the live stores: Fuzzball’s monthly plan and Sensational Eyes’ before and after

Built for Drink Finder, East at Home and Fuzzball. Two wins at the UK eCommerce Awards 2026, designed by Anthony Bliss, built by Cartmasters.

How we work

We build it, then we stay.

A small studio, from the first brief to every fix after launch.

  1. 01

    We build it

    Rebuilds, migrations onto Shopify, subscriptions and new features. We work with your own designer, or alongside design partners such as Anthony Bliss, who designed Drink Finder and East at Home.

  2. 02

    We look after it

    We stay on after launch. The people who built your store are the people who look after it, so nothing gets lost in a hand-over.

  3. 03

    We keep improving it

    After launch the work carries on: bundles, a clearer basket, faster pages. On East at Home that has meant add-on suggestions in the basket, add to basket that stays in view and a free delivery bar, a piece at a time.

  4. 04

    You see every change

    Each change comes with a before and after, on a phone and a desktop, and a link to where you’d change it yourself. We use AI to keep track of every request and to check our work, and every change is built and reviewed by us.

The log

Everything we ship, as it ships.

Every change a shopper or store team would notice, big or small, newest first. Our own clients are named; agency work is described only by type.
