our mission

Brands deserve their own space

The goal of the project was to enable brands on Allegro to present themselves in their own way – simply, without programming, and with full control over content. StoreInStore gave sellers the ability to create their own stores using an intuitive editor and unified management across markets and devices.

challenges

Three worlds – one ecosystem

Mall, CZC, and Allegro – three platforms, three different approaches, one common goal. We needed to unify data, maintain performance, and create a solution that could handle thousands of brands and users. All of this in an environment where dozens of teams operate and development runs in rapid iterations.

solution

A universal editor to rule them all

We contributed to the development of an editor where brands can assemble their own store – from banners to product blocks. Drag-and-drop, intuitive interface, dozens of components, and analytics in the background. The result is a system that is flexible, performant, and easily scalable to other markets.
