Company History

Younify started in 2007, focusing on communication and long-term client relationships. Initially aimed at building webshops, we chose Magento for its suitability for successful online businesses. In 2010, we opened an office in Serbia, with a strong development team and management in Niš. We organised Meet Magento Serbia and Hyva Meetup conferences, which have contributed significantly to e-commerce development in Serbia. We are also recognised as a leading Magento development company, an official Hyva Gold Partner, and an active member of the Magento community. We are also part of the Serbian Chamber of Commerce and the NiCAT Advanced Technology Cluster for IT Innovations. Today, we focus on the Dutch market with over 30 Hyva shops developed and 500+ Magento projects in our portfolio.
