About Us

Diadem was founded in 2015 with a single goal in mind - develop the most innovative, high-quality tennis products in the world to help players maximize their performance. We found that the tennis industry had become stagnant, with very few brands that were challenging the status quo. With a team made up of former collegiate and professional players and coaches, Diadem set out to develop new and exciting products that catered to players of all levels looking to elevate their game.

As the last American tennis brand, all of our products are designed and developed in our global headquarters located in the heart of the hottest tennis market in the country - Fort Lauderdale, Florida. Our extensive research and rigorous testing process ensures that every product we develop meets superior levels of quality. Through our combined 100+ years of experience as tennis players and coaches, we've identified challenges in the industry where tennis equipment has failed its players, and developed the solutions to overcome those challenges.

Our flagship string was our six-pointed Solstice Power, and its patented Star Core Technology, designed for massive spin and insane ball bite. From there, we released 4 other variations of string all developed with a specific player in mind. After explosive growth in the early history of Diadem, we were then able to design our performance rackets - Elevate 98 and Nova 100. We currently offer a full product-line of performance tennis gear including strings, rackets, balls, bags, grips, and accessories.

Team Diadem has continued to spread as several of the top colleges, coaches, and junior players embrace our brand and what we represent. With worldwide partners and distributors, Diadem is making a global impact in the tennis market - and we're just getting started.
