The Slopegraide Story

"In 2017, I remember how frustrated I was after missing every single birdie putt on the low side of the hole during my round.  My green reading was off, I didn't make any birdies, and I wanted to get to the practice green immediately to work on my green reading.  But I knew how cumbersome and silly it was to move a digital level around the practice green.  There had to be a way to make this process quicker and easier.  In that moment, the idea of Slopegraide was born."

Anyone who has played golf knows the frustration of misreading a putt on the green.  We recognized that there was a missing piece in the golf technology industry.  Distance rangefinders and GPS technologies help golfers get from tee to green, but once golfers are on the green, they are essentially on their own.  Many training aids for putting help a golfer's putting stroke, but at the time, there wasn't any individual training aids that helped with a golfer's green reading.  We saw an opportunity to contribute to the game and make a lasting impact on the overall enjoyment of golf for many years to come.  


In understanding the challenges of green reading, we combined engineering talents to create an easy to use tool that will accelerate growth and development in green reading skills and help build confidence in golfers of all skill levels when stepping onto the green.  

With you, the golfer in mind, we created Slopegraide, golf's first wearable green reading system that takes your stance and provides you slope information in real-time to your iPhone or Apple Watch, like a rangefinder.  This information will help you eliminate self-doubt and guesswork with how your putt will break, so you can make more putts, lower your scores, and create your moment on the course.
