Our Story
John learned to play both golf and platform tennis around the age of 40. While the two sports had surprising similarities, the learning experience couldn't have been more different.
In golf, every lesson came with a roadmap. A simulator could track progress, offer real-time feedback, and reinforce improvement. But in racquet sports, there was nothing like it. No objective ratings. No data-driven development. No way to know where you stand or what to work on.
So Dan and John set out to change that, building the world's first AI-enabled racquet sports assessment and rating system. Today, Volley is used at clubs across the country, giving players and clubs the objective data they've been missing.
