9 December 2025
The subject Creation, Organisation and Management of Companies, taken in the second year of the Master's Degree in Industrial Engineering and the Master's Degree in Telecommunications Engineering (Comillas ICAI), once again became a true laboratory of innovation thanks to a new edition of the Unicaja Challenge. On this occasion, more than 150 students, organised into teams of three, worked for weeks to develop solutions that would reinvent financial services aimed at young people through the use of crypto technologies.

The finalist projects were evaluated by a mixed jury made up of professionals from Unicaja, Estrella Botas, General Manager of Technology and Operations; Israel Rodríguez, Director of Innovation; and Benoît Courtois, Director of Blockchain and Digital Assets; and representatives from Comillas, Enrique Marazuela, Director of Economic Affairs and Business Relations; Alexis Cantizano, Deputy Academic Director of the Higher Technical School of Engineering (Comillas ICAI); and Oriana Circelli, Director of Comillas Emprende.
The winning team, made up of Laura Muñoz Pérez, Antonio Rébola Iranzo and Carlos Morales Campoy, presented "Un euro al día" (One euro a day), a micro-investment platform for young university students that proposes investing one euro a day automatically according to the user's profile. The application incorporates a gamified financial education itinerary, designed to encourage saving habits and improve students' financial literacy.
The challenge was coordinated by professors Susana Ortiz Marcos, Alejandro González San Román, Rodrigo Martínez Díez and Guillermo Estévez de Comingues, who highlighted the quality of the proposals and the high level of student involvement. For many participants, it was their first real contact with open innovation processes and direct work with a company.
Beyond the prize, the experience made it clear that when students are faced with real challenges, ideas flourish.
