About Us
Our Origin 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 between them couldn’t have been more different.
In golf, every lesson came with a roadmap. A simulator could track progress, offer real-time stroke feedback, and reinforce improvement. It was structured, measurable, and engaging. Racquet sports, on the other hand, felt like a guessing game. Lessons, clinics, and pickup play were loosely connected—and provided little objective feedback. The path to improvement was unclear.
Despite this, John loved the physical intensity and movement of racquet sports. But when he had an hour to spare, it was golf—not paddle or tennis—that got his attention. Golf simply made it easier to practice with purpose.
That contrast sparked an idea: what if racquet sports had a training system as engaging and data-driven as golf? One that could track progress, simulate real match conditions, and provide feedback anytime, anywhere?
That idea became the Volley Trainer—and it remains central to everything Volley does. Unlike golf, where the ball is stationary, racquet sports require movement from both the player and the ball. Recreating that complexity in a repeatable, intelligent way was the challenge.
Building the first machine was just the beginning. It’s now a full training experience—designed to help every player improve with clarity, confidence, and a community behind them.
