Part II, The Founders, gave background on how our team came together. Today we’re giving you all the details of what we have been developing for the past year in regards to our smart golf ball.

At Graff, we’ve all similar experiences in the sport of golf—and similar frustrations with the lack of available technology. So, we set out to create a golf ball that would help us improve our games more efficiently.

So, why a smart golf ball?

We could’ve gone down a few different roads when exploring the idea to bring more technology to golf. But we envisioned a training tool that would allow us to play live holes while we used it—because, well, golf’s just more fun on the course. So the team set out to build a ball that could track key metrics for every shot, and then derive specific insights into what a golfer can do to improve their game most efficiently.

Through detailed research and talks with professional trainers, we identified six key metrics that we need the ball to track: spin rate, spin direction, velocity, launch angle, score, and location. These metrics became the building blocks for determining the quality of a swing, as well as being able to diagnose how to improve it.

Using various physics-based extrapolations, the ball can measure each metric isolated from external factors—such as wind. It’s important to be able to know the true consistency of a golfer’s club regardless of the conditions.

For example, we can track how far your drive would have gone—had it not hit that tree.

We each make a lot of mistakes in one round of golf. At Graff, when we shared our golf experiences, we realized how hard it is to accurately analyze our play and to determine what we should work on to get better. This was a key insight we used to develop how the ball should communicate with the smartphone app.

At the conclusion of a round or training session, the app will provide the user with data-driven insights into some of the weakest parts of their game. Using a number of statistical methods, we can not only determine which club was the least consistent—but also gain an idea of what is happening in the swing to create the inconsistency. The app will draw conclusions from the ball data as to how and why certain aspects of a golfer’s game could be improved. These conclusions will be followed by specific drills and insights on how to improve upon that conclusion.

The Graff team is working tirelessly on a product that we truly want and need to improve our golf game, and we cannot wait to share it with the world.

See you here next week for Part IV, The App.
