Achraff Adjileye is a research engineer passionate about football analytics and artificial intelligence. He is the founder of the BALLER project, which aims to build a foundational model for football analytics—powering the next generation of context-aware football analysis, much like GPT revolutionized text understanding.

His vision: Football is the ultimate team sport, yet most analytics treat players as isolated individuals. Players are often represented by radar charts of individual statistics, ignoring the rich collective context that shapes their identity. While this approach transformed data-driven scouting, it is inherently prone to misinterpretation, leading to costly mistakes in transfers and strategic decisions. Achraff works every day to create a football analytics world that respects the collective DNA of the beautiful game.
