GWO is one of the first privately owned educational publishing houses in Poland, established in 1991, and currently ranks as the second most popular textbook publisher in the country. Their flagship mathematics series, "Matematyka z plusem," is used by the majority of primary school students in Poland. Over the years, the company has grown well beyond traditional textbooks - today their portfolio spans digital courses, interactive maps, teacher tools, e-books, and more, all managed by an in-house development team. With multiple sales channels serving different customer segments, and 350,000 orders processed annually, the platform holding it all together needed to be more than just functional.
