# GUD Baseball > GUD Baseball (Ground Up Development Baseball LLC) is a pitching velocity development program for high school and college pitchers and their parents. We measure each athlete's delivery, mobility and power with wearable sensors, find what is capping their velocity, and build an individualized throwing, strength and arm care plan around it.
