Webmefy: Technology, Data, and Growth for Scaling eCommerce

At Webmefy, we help brands build, optimize, and scale their eCommerce by combining technology, analytics, and growth strategies. As a Shopify Premier Partner and Klaviyo Master Platinum, we work with companies that want to turn their online store into a real growth engine.

As a Shopify agency in Madrid, we collaborate with brands looking for a solid technological infrastructure and data-driven strategies to scale their online business.

Our approach starts from a clear idea: sustainable eCommerce growth requires a solid technological foundation, data-driven decisions, and marketing strategies focused on profitability.

Webmefy is pronounced: [Web-me-fy]

The founders

Webmefy was founded by Gabriel and Aurora after years working in technology, marketing, and digital projects. During that time, they identified a recurring problem: many companies invested in marketing without having the technological infrastructure or a data-driven strategy ready to scale.

To understand the challenge from within, they decided to create and operate their own Shopify eCommerce store, experiencing firsthand the challenges of technological architecture, acquisition, conversion, and customer retention.

Shortly after, at a Shopify meetup, they met who would become their first client. That encounter led to an ambitious project: designing a Shopify eCommerce architecture ready to operate in several countries, marking the beginning of Webmefy.

Since then, the agency has grown by supporting brands looking for more than just a provider: a strategic partner to build and scale their eCommerce.
