Stopper is the world leader in developing software that tracks and analyzes goalkeeper game performance in soccer. Stopper's proprietary algorithms segment game data into key performance areas that collectively provide a comparative framework for analyzing individual goalkeeper strength and weaknesses. Compared to current player metrics, study findings demonstrate that using Stopper provides a more meaningful characterization of individual goalkeeper performance and ability. In partnership with MLS teams, we're developing Stopper Pro, a full-featured SaaS platform that lets professional clubs and organizations track and analyze multiple goalkeepers with a powerful suite of performance and video analysis tools.
