Ubuy, a Kuwait-based e-commerce company, is expanding its global reach by offering products from over 180 countries through its app and website. To support this growth, Ubuy adopted MongoDB Atlas to address scalability and search performance issues. The company migrated from MySQL to a fully managed MongoDB Atlas environment, implementing both MongoDB Atlas Search and MongoDB Atlas Vector Search to improve search efficiency and relevancy. With these enhancements, Ubuy has seen significant improvements in search response time, customer engagement, and business growth, including reduced search response times to milliseconds, over 150 million search queries handled annually with improved relevancy, and higher engagement on product pages due to AI-enriched content. Looking ahead, Ubuy aims to optimize search by consolidating inventory visibility across multiple stores, further enhancing its position as a leader in cross-border e-commerce.
