Founded in 2017 by Joe Kalfa, Slinger Bag emerged to democratize access to effective racquet sports training. Frustrated by the high cost and bulky nature of traditional ball machines, Kalfa designed a portable, affordable launcher that doubles as a multifunctional tennis bag. The brand's flagship product, the Slinger Launcher, holds up to 144 balls and features adjustable speed, elevation, and feed frequency, allowing players to practice independently.
