Case study — A/B test + Redesign

MyVariations takes back control of its store with Theme FullStack.

Challenge 01

Take back control in-house

The team depended on external integrators for the smallest change. The goal: a store the team can evolve on its own, with no development skills required.

Challenge 02

Eliminate app debt

The store ran on a pile of third-party apps for the cart, upsells and CRO. Every app = a point of technical friction, a JS conflict risk, and a monthly cost.

Challenge 03

Migrate without losing hard-won gains

MyVariations had years of optimization built in. The redesign couldn't start from scratch — every UX detail had to be reproduced, then improved.

A brand whose theme had become a bottleneck

MyVariations, one of France's leading e-commerce brands in its category, had reached a point where its existing theme was holding it back rather than driving growth. Too many apps, too many dependencies, too little flexibility.

Theme FullStack emerged as the natural solution: a 100% proprietary foundation built for brands that have already reached a high level of maturity.

lamp case study context

MyVariations is one of the first major French DTC brands to migrate its store to a Shopify theme sold outside the official theme store — a strong signal of Theme FullStack's credibility.

Rebuild exactly as is.
Then make it better.

The golden rule of a successful migration: don't start from scratch. We first faithfully replicated the existing setup to protect performance, then leveraged FullStack's native capabilities to eliminate friction points.

Before

Third-party cart app (JS conflicts)

Dev dependency for every change

External CRO app stack

Degraded load times

Hard-to-maintain storefront

After

100% native FullStack cart

Autonomous editing, no dev needed

CRO built in natively

Optimized Core Web Vitals

Consistent design system

1

Comprehensive audit of the existing store

Mapping of all components, UX behaviors, and active apps. Identification of friction points and native opportunities.

2

Identical migration to FullStack

Faithful reconstruction — same structure, same content, same information architecture — on the FullStack foundation.

3

Replacing apps with native components

The cart managed by a third-party app is replaced by a native FullStack component. Reduced JS conflicts and immediate performance gains.

4

Activating native CRO features

Upsells, subscriptions and trust elements straight from the theme — no additional app, no extra monthly cost.

5

Training and handover to the in-house team

The MyVariations team is trained to run and evolve the store in full autonomy, with no external dependency.

An 83.2% result is statistically solid across ~10,000 transactions. The classic 95% threshold hasn't been reached yet — consistent with the test duration. Trends converge across all metrics.

Why FullStack was the right decision

The FullStack Theme is not a generic theme. It is 6 years of expertise condensed into a single codebase — 100% proprietary and built for performance.

01

Native components = less technical friction

Every feature is built natively into the theme. No conflicting third-party apps, no asynchronous loading, no hidden technical debt.

02

6 years of expertise condensed into every line of code

FullStack is 100% proprietary code — not a third-party base, not a fork. It is the culmination of 6 years of cross-functional expertise: Shopify development, CRO, UX design, A/B testing, analytics, marketing, and human psychology.

03

Operational freedom for internal teams

Migration empowers teams to iterate independently without external dependencies. Every FullStack update automatically enhances your store.
