The research and development related to Yusp started at the Faculty of Scineces of Budapest University of Technology and Economics when a diverse team of individuals decided to participate on the Netflix prize. After years of hard work and competing with tens of thousands of contender, the team led by the group (The Ensemble) tied for first place. Since then, the scientific orientation of the company just grew stronger with several PhD holders on board, resulting in patents, regular publications in the most notable journals, numerous awards, and participations in many EU funded research projects.
