MM Shopy Devs S.L.

MM Shopy Devs is a certified Shopify Plus Partner agency with nearly a decade of exclusive Shopify expertise, serving fashion, luxury, and high-growth DTC brands across Europe and globally.

Founded in London in 2017 — with roots on the platform going back to 2015 — we have designed, built, and scaled Shopify and Shopify Plus stores for some of the most demanding brands in e-commerce, including Nude Project, Hunza G, Marfa Stance, Cassandra Goad, and Bottletop. Our work spans custom theme development from the ground up, complex platform migrations from WooCommerce, Magento, PrestaShop, and headless architectures, as well as precision theme customisation and conversion-focused UX design.

We operate as a specialist boutique, not a generalist agency. Every service we offer is Shopify-specific, every developer on our team is senior-level, and every client engagement is handled with direct access to the experts building their store — no account managers, no ticket queues, no communication layers. Clients integrate our team into their workflow via Slack or their preferred channel and receive real-time, expert-level responses from day one.

As certified Shopify Plus Partners, we are recognised by Shopify for consistent delivery of high-complexity, high-impact projects for enterprise and fast-scaling brands. Our Shopify Plus expertise covers custom theme architecture, international store rollouts, platform migrations with full SEO and data integrity, and ongoing technical strategy for brands operating at scale.

Key credentials:

• Certified Shopify Plus Partner — awarded for sustained excellence across enterprise-level projects
• Specialists in custom Shopify theme development, built for performance, scalability, and brand precision
• Extensive migration experience: WooCommerce, Magento, PrestaShop, and headless-to-Shopify transitions
• Senior-only team — every project receives principal-level technical attention

For fashion houses, luxury labels, and DTC brands that require a Shopify partner with the technical depth, platform authority, and boutique responsiveness to match their standards, MM Shopy Devs delivers.
