Zenniz Completes $6 Million Raise, Establishing USA HQ
Zenniz, the world's leading provider of smart tennis court solutions, successfully completed a new $6M USD funding round backed by multiple VC funds.
The investors include Nordic funds, Butterfly Ventures and Superhero Capital, Seventure Partners from France, and a South American fund, Bromélia Capital. Miki Kuusi, the founder of food delivery giant Wolt, also joined as an investor.
The raise will accelerate Zenniz’s ongoing global growth. With systems already in operation on 4 continents and in over 25 countries, the Finland-based company is now establishing its North American Headquarters in Atlanta, Georgia.
"First and foremost, we warmly welcome our new venture capital investors. Currently there is strong momentum in sports tech and our VC’s expertise in hardware startups, U.S. markets, and background in tennis makes this a perfect match. Tennis as a sport is modernizing, and our comprehensive all-in-one solution is resonating extremely positively throughout the industry”, commented Zenniz CEO Eero Kuusi.
The investment comes after a record-breaking 2025, not only in sales but also in establishing the company as the go-to smart tennis court partner for industry leaders through partnerships with the likes of Tennis Warehouse and Mouratoglou Academy. Earlier in June 2025, Zenniz also became one of the first vendors in the world to be certified by the International Tennis Federation (ITF) for line calling in international tournament play for club-level systems.
“We are super excited to lead the charge with Zenniz as they cement their position in the U.S. I played competitively since I was 6, including USTA and Collegiate sanctioned tournaments, and can’t describe how inspiring it is to have a front row seat in seeing the advantages of the Zenniz become evident in the ecosystem. This genuinely is shaping up to be a revolution”, mentioned Tanya Horowitz, Partner, Butterfly Ventures.
“Being heavily involved in tennis especially in Brazil and across the latin american world, investing and joining forces with Zenniz is an opportunity of a lifetime. Together we are determined to help tennis and racket sports take important steps forward, benefiting everyone from the pros and club managers to people brand new to the sport”, says Jefferson Plentz from Bromélia Capital.
After releasing their 2nd Generation hardware and AI powered Zenniz premium services in 2025, Zenniz is now setting its sights on expanding the services provided throughout its ecosystem.
"We are now ready to seriously scale up our operations. At the same time we have the resources to start pushing out many features both on and off court, that we, as users of the systems, have been dying to implement. It’s going to be such a great year for both new and existing Zenniz users”, finishes Eero Kuusi.
