Founded in 2015, Diadem had a clear vision - to revolutionize the industry by creating innovative, top-tier products that would optimize players' performance. Recognizing a lack of innovation among tennis brands, our team, composed of former collegiate and professional players and coaches, set out to develop cutting-edge products suitable for players of all levels.

Beyond tennis, we extended our expertise into the booming Pickleball industry.  Diadem has made a significant impact in both the tennis and pickleball markets. Our product line now includes strings, rackets, paddles, balls, bags, grips, and accessories for both sports.
