I am Joe. Founder of Slinger®.
Like you I love to workout playing Tennis each day. However, I constantly found myself
challengedto find a playing partner.
So I decided to try the club ball machine. Ugh! Having taken me 30 minutes to drag it to the
courtand locate cables and power, even more time was wasted figuring out how it actually
worked!
Frustrated I gave up. This experience led to my idea to create a ball machine built into a
regularsized roller trolley bag. Eureka! Slinger® was born! A lightweight, transportable,
versatile and affordable Tennis Ball Launcher. All my tennis gear in one place together with a
Ball Launcher that can be set up anywhere within a few minutes. My 24-7 Tennis Partner!
Thank you for being on this journey with me.

Founder
I am Mike. CEO of Slinger®.
I have been involved in tennis all my life, playing, coaching and running tennis businesses. I
know the challenge our sport has in both retaining current players and attracting new players. Of
tennis players who left Tennis in the past 12 months, 34% did so due to the lack of a partner to
play with.
Slinger® helps to solve this problem. Re-Inventing Tennis, making it accessible to all.
Following thousands of hours of design, prototyping and both on and off court testing, we have
taken Joe’s idea and transformed Slinger® into a performance piece of tennis equipment.
Slinger®a tennis innovation for players of all ages and abilities.
Thank you for supporting Slinger®. Designed by Players for Players.
