Graff Golf, with a $3 million valuation cap, is raising crowdfunding on WeFunder. Graff Golf is creating smart golf balls with patented electronics to analyze the statistics of golf shots. The technology combines the benefits of launch monitors, rangefinders, and other game-enhancing technologies to help the players improve their games affordably. The same business model is expandable to other games like baseball, soccer, tennis, and softball. Graff Golf is led by Aaron Shapiro, and the product is being developed by John Hopkins engineers. The proceeds of the current crowdfunding round, with a minimum target of $20,000 and a maximum target of $100,000, will be used towards development and testing, marketing, and initial inventory. Graff Golf generated over 8,000 unique views on its website last month and has partnered with the largest golf ball manufacturer in the US.
