Tennis Warehouse Partners With Zenniz to Put Hard Data Behind Gear Reviews
The world’s largest online tennis retailer will use Zenniz’s AI-driven court analytics across video, social, and product pages to validate gear claims and boost buyer confidence. By adding objective on-court data to its reviews, Tennis Warehouse aims to raise the standard for racket and string testing and give players a clearer view of how gear performs.
San Luis Obispo, CA / Helsinki, Finland | September 30, 2025 — Tennis Warehouse, the world’s largest online tennis retailer, has partnered with Zenniz to introduce AI-driven smart-court analytics into its racket and string testing process. The partnership makes Tennis Warehouse the first major tennis retailer to embed objective performance data into its reviews, product pages, and video content.
Data-Driven Insights Add Objectivity to Gear Reviews
Using Zenniz’s smart-court system, Tennis Warehouse’s team of six testers will run on-court drills that generate objective performance metrics. The data will be integrated into Tennis Warehouse’s YouTube reviews, Instagram content, product detail pages, and in-depth write-ups on Tennis Warehouse University.
“We’re so excited to partner with Zenniz to bring our viewers and customers deeper, data-driven insights into our racquet and string reviews. This advanced technology allows us to quantify what we feel on court, from depth and spin to control and power,” said Chris Edwards, Director of Web Content at Tennis Warehouse. “Our community has been asking for this level of analysis for a long time, and we’re thrilled to deliver it once again. Not only does Zenniz’s system enhance the accuracy of our reviews, but it’s also incredibly fun to use, making the entire testing experience even more engaging.’
For Tennis Warehouse, the addition of Zenniz data represents a major operational upgrade: faster, more consistent testing protocols, richer storytelling for product launches, and an authoritative benchmark for gear claims across the industry. For consumers, it means one of the most trusted retailers in tennis is putting objective, comparable data directly into their hands when making purchase decisions.

“This is a milestone for us,” said Santtu Leskinen, CMO of Zenniz. “From the start, we said that when Tennis Warehouse adopts our technology, we’ve reached a level of credibility that matters across the entire tennis world. What set us apart for them – and for the clubs and universities we already work with – is the combination of accuracy and completeness: Most systems can track something well, but Zenniz delivers precise line calls, full match stats, and comprehensive shot analytics in one package. That’s the standard Tennis Warehouse wanted, and that’s the standard we now bring to players everywhere.”
Zenniz currently supports both indoor and outdoor environments and is already in use at Yale University, JTCC in College Park, Grand Rapids Racket & Fitness (one of the most active USTA tournament hosts), and Mouratoglou Academy in Nice, to name a few.
