Sdui develops and provides innovative operating systems designed for digital schools and preschools. The company offers a comprehensive platform that simplifies communication and organization within educational institutions through smart functions. These capabilities include chat, translation tools, cloud storage, digital class registers, and AI-powered lesson planning, all tailored to the specific needs of schools and daycare centers while adhering to GDPR compliance.
The genesis of Sdui traces back to 2015 when founders Daniel Zacharias and Jan Micha Kroll, then students, recognized a need for better digital communication regarding school events like cancelled lessons. They initially developed a digital solution, "Basic P," for a student competition. Following positive reception and demand, they officially founded Sdui GmbH in Koblenz in February 2018, launching their app to initial customers later that year.
The platform serves teachers, educators, parents, and children, aiming to connect them efficiently and reduce administrative burdens. Sdui's overarching vision is to empower individuals to transform education for a better tomorrow, fostering a world where technology ensures everyone can participate in and benefit from the best possible learning experiences, making education more effective and globally accessible.
