About MM Shopy Devs – Shopify Plus Partners
MM Shopy Devs is a boutique Shopify Partner agency and certified Shopify Plus Partner. Since 2017, we have specialized in building high-performance Shopify and Shopify Plus stores. Our expert team delivers tailored e-commerce solutions, custom themes, and fast, honest support that helps ambitious brands grow and scale globally.
Our Story & Shopify Partner Journey
Our journey began in 2015 when our founder Marco Mattiello started working with Shopify, just as the platform was making its mark in the UK. In 2017, we became an official Shopify Partner and founded MM Shopy Devs in London to help ambitious brands succeed with Shopify.
During our time in London, we collaborated with forward-thinking businesses including Private White, contributing to their growth amid a booming e-commerce scene. In 2020, we relocated to Barcelona, entering a market dominated by CMS platforms like PrestaShop. There, we helped emerging brands such as Nude Project scale using Shopify’s modern tools.
Our team’s unwavering commitment to integrity, expert craftsmanship, and honest communication earned us recognition as a Shopify Select Partner, and most recently, as an official Shopify Plus Partner. Having built, migrated, and optimised stores for brands operating at scale, we stay at the forefront of the Shopify ecosystem. Today, we continue to deliver real results and unlock new opportunities for our clients on Shopify’s most advanced platform.

Our Approach
Our direct approach to Shopify development sets us apart. At MM Shopy Devs, our integrity and direct communication set us apart from other Shopify Partners and Shopify Plus Partners. In this industry, many agencies create a barrier between clients and the actual experts working on their Shopify stores. Clients are often required to communicate through multiple project managers and complex ticket systems, which can slow down operations and reduce transparency.
We believe in doing things differently. Our clients always communicate directly with our Shopify experts, ensuring their questions and needs are addressed quickly and efficiently. By using tools like Slack for real-time messaging, we make sure that support and solutions are never delayed.
This approach leads to faster results, better collaboration, and a partnership built on trust. As certified Shopify Plus Partners, we are dedicated to providing genuine expertise and open, honest communication with every client.

For our clients, working with a certified Shopify Plus Partner means choosing a team with hands-on experience delivering complex and high-impact Shopify Plus projects. We have helped brands transition from other platforms, launch innovative features, and manage growth using the advanced capabilities of Shopify Plus.
Unlike larger agencies where clients often feel disconnected from the experts working on their store, we keep things simple and direct. Our boutique approach means our clients work closely with certified Shopify Plus experts who understand their business and goals. Every project receives senior-level attention, from strategy and design to development and post-launch support.
As Shopify Plus Partners, we are also part of an international community of top Shopify agencies. This recognition allows us to stay ahead with the latest platform updates, best practices, and industry insights—giving our clients an edge in the fast-changing world of e-commerce.
