About MM Shopy Devs

Our story

Based in Barcelona, roots in London

From Shopify's early years to its most advanced platform.

  1. 2015

    Marco Mattiello starts working with Shopify, right as the platform was taking off in the UK.

  2. 2017

    We become an official Shopify Partner and found MM Shopy Devs in London, to help ambitious brands succeed with Shopify.

  3. London years

    We collaborate with forward-thinking businesses like Private White VC, contributing to their growth amid the ecommerce boom.

  4. 2020

    We move to Barcelona, a market dominated by CMS platforms like PrestaShop, and help emerging brands like Nude Project scale with Shopify.

  5. 2025

    We were awarded with the Shopify Plus partner certification.

  6. Today

    Recognised as a Shopify Select Partner and, more recently, an official Shopify Plus Partner. We build, migrate and optimise stores at scale.

How we work

Our approach

Many agencies put layers between you and the people actually building your store: project managers, ticket queues, slow replies.

We don't. At MM Shopy Devs you work directly with senior, certified Shopify experts, in real time, so questions get answered and decisions get made fast.

Our boutique model means every project gets senior-level attention from strategy through to post-launch, and a relationship built on integrity and honest communication.

Shopify Plus Partner

What it means to be a Shopify Plus Partner

Shopify Plus Partner status is awarded only to agencies with proven expertise, a consistent track record and the highest service standards.

For you, it means a team with real, hands-on experience on complex, high-impact Plus projects, from platform migrations to custom development and growth at scale, and a direct line to certified experts rather than a disconnected account team.
