Diamond Kinetics

Diamond Kinetics (DK) is a Pittsburgh, Pennsylvania sports-technology company focused on youth baseball and softball development. Its core products are a bat sensor that attaches to any bat and streams swing data in real time to an iOS app, a permanently embedded knob sensor built into the Marucci smart bat line, and the free DK mobile app that turns sensor and motion data into metrics, lessons, challenges and games. The company describes an emphasis on connected devices, computer vision functionality and virtual reality integration in affordable, portable mobile technology.

The DK App provides SmartMotion swing challenges and guided hitting lessons, a Diamond Decision highlight arcade, MLB PLAY BALL challenges, and SwingMatch, a body-tracking feature that matches a user's swing to a Major League player. With a bat sensor connected, users see real-time swing metrics such as barrel speed, acceleration and attack angle, plus a proprietary Swing Score that condenses 11 swing metrics into a single number across power, speed, control and quickness categories, recalculated every 100 swings. A DK+ subscription unlocks premium content including featured-player guided lessons. Following its 2024 acquisition of SidelineHD, the company also offers free game livestreaming, automatic highlight clips, post-game recaps, box scores and team highlight reels, with AI-generated personalized lesson recommendations announced as forthcoming.

DK positions its sensor-based motion technology and analytics engine, built on millions of swings recorded annually, as an evaluation and development toolset for players, parents, coaches and scouts, supplying benchmarks and thresholds across key swing metrics. The company also publishes a developer API.

Founding story

The company was co-founded by CJ Handron, who serves as Chief Executive Officer, and William Clark. The company describes its origins as a family project.

Business model

Diamond Kinetics sells hardware and software to consumers and licenses/partners with baseball and softball organizations. Revenue sources indicated by the company include sales of the DK Bat Sensor (including via Amazon), sensor-equipped Marucci smart bats sold through Marucci, and the recurring DK+ subscription that unlocks premium in-app content. The core DK app and the SidelineHD livestreaming service are offered free, with the subscription and sensor as the paid upgrade path.

Hardware sales (bat sensors and sensor-integrated smart bats) combined with a recurring DK+ consumer subscription for premium app content; free app and livestreaming tiers act as the acquisition funnel. A third-party profile estimated annual revenue in the $10M-$25M range as of July 2026.

Traction

The company states its analytics are based on millions of swings taken each year and that its technology is used by MLB, USA Baseball, USA Softball, Perfect Game, Alliance Fastpitch and PONY. MLB partnered with and invested in the company in 2022, and MLB and the MLBPA are listed among its investors. A third-party profile estimated roughly 38 employees and $10M-$25M annual revenue as of July 2026.

Latest developments

In January 2026 Diamond Kinetics announced a $12 million funding round led by Elysian Park Ventures, the investment arm of the Los Angeles Dodgers' ownership group. CEO CJ Handron said the capital would expand youth baseball and softball offerings, scale SidelineHD's livestreaming and AI-powered highlight services, strengthen development capabilities, deepen content services and build on its role as MLB's Trusted Youth Development Platform. The company has also signaled forthcoming AI-generated personalized lesson recommendations based on game play.
