Mustard

Mustard, co-founded by pitching coach Tom House, provides personalized athletic assessments and training that elite athletes receive, delivered through a mobile app. Users record short videos of a pitch or swing, submit them, and receive a report card with mechanical metrics, key still frames, stick-figure mechanics, and a personalized training plan. The platform covers baseball pitching mechanics, mental approach, and physical conditioning, and also offers Mustard Golf and a coach platform that puts House's decades of mechanics data in a coach's pocket. Featured MLB pitchers and youth athletes use the app for real-time analysis and instruction.
