Zenniz is proud to announce a partnership with Decathlon, the largest sporting goods retailer in the world. 

As Decathlon's Official Tennis Equipment Testing Partner, Zenniz is helping Decathlon set a new global standard for objective, data-driven tennis equipment testing—marking a landmark step forward for Decathlon customers worldwide.

Together, Zenniz and Decathlon are developing a dedicated testing tool that uses Zenniz technology to objectively measure the performance of Decathlon's tennis racquets and balls — tracking metrics including shot speed, net clearance, and depth. At the heart of this partnership is a shared belief: that product quality should be proven with data to provide all players with the best equipment available.

For Decathlon, the investment in testing equipment is a statement of confidence. Their tennis equipment is technically on par with premium brands — and now they have the tools to demonstrate it. The partnership reflects Decathlon's broader commitment to transparency and evidence-based product development, going beyond standard testing to co-build a purpose-built solution with Zenniz.

"In tennis, marketing often leads over science. With Zenniz, we now have the tools to change that — to objectively demonstrate what our products are truly capable of. Technically speaking, Decathlon's equipment is on par with the best in the market, and we want the data to prove it."

— Jean Philippe Richard, Product Engineer @ Decathlon Tennis

The next testing sessions are planned for later this summer, with data being already gathered and analyzed in Decathlon’s French testing location.
