Testimonials
Lassi Nykänen
DIRECTOR OF COACHING AND DEVELOPMENT AT SMASH TENNIS
The system definitely calms things down on the court. I didn’t have to solve any line call disputes on the court and the players’ stress levels seemed lower, so there were fewer instances where I had to keep an eye on their conduct. The live stream and live scores allowed me to keep track of the matches from the tournament desk, which made my job a whole lot easier.
David Gustafsson
CLUB MANAGER AT FAIRPLAY TK
We are very excited about the Zenniz technology that is available for use in our facility; Zenniz as a product is a ‘perfect match’ for our needs. It is simple and fun to use, suitable for both competitive players and recreational players.
Chris Drake
MEN'S TENNIS HEAD COACH AT YALE UNIVERSITY
We're super impressed with the system, especially with the ease of use in the match play. When it comes to line calling and overall match experience, it’s the best we've seen. We had a couple of disputes about some calls and the device resolved them quickly.
Martin Killemose
HEAD OF TENNIS AT KB TENNIS
Our experience with Zenniz has been extremely positive. Players have been keen to try the system as it is easy to use. The coaches love it and use it almost every time. For us, it's a new thing to go the IT way and look at tennis in a different way.
Sébastien Tesson
HEAD COACH AT SNUC TENNIS
SNUC’s members and coaches love the new technology. A technology that enables electronic line calls and challenges in tournaments, and brings players into the world of statistics, highlight videos, and streaming. Just like at the professional level. Zenniz is easy to use and efficient. The drill system is excellent.
Anna Wilk
MARKETING MANAGER AT TENNIS KOZERKI
Zenniz is a concrete source of feedback. The system allows players to monitor their progress even when a coach isn’t present. Our players really appreciate the ability to record matches and perform detailed game analysis. For professional players, it’s an essential tool. It enables real-time analysis, enhances training techniques, and allows them to revisit recorded material later for in-depth review.
Mateusz Zając
LESZNO TENIS KLUB
When building our new tennis hall, we wanted to look for modern solutions that would allow us to take the game of tennis to a higher level. That’s why we chose Zenniz. The system can be used by players of all skill levels and ages. Thanks to the extensive statistics, players can monitor their progress. Professional players and coaches highly value the drills that Zenniz offers, which allow them to diversify their training, check results, and analyze their game in real time.
Tom Walker
DIRECTOR OF TENNIS OPERATIONS
Zenniz is a complete package as opposed to dealing with different providers. The playing experiences are frankly unreal and makes the matches flow.
Pekka Mäkelä
EXECUTIVE DIRECTOR AT HVS-TENNIS
The best system in the world. First and foremost, we want to provide the best possible conditions for everyone to play tennis. The initial reaction to Zenniz is always positive and players receive data about their matches that they’re not used to, along with videos instantly sent to their phones.
Juho Antila
DIRECTOR AT NALLISPORT TENNIS CLUB
The players’ first reaction is always ‘Wow, this is so cool!’ People started booking the Zenniz courts right away. We keep asking ourselves: how can we create added value for our customers? Zenniz delivers that.
Petja Nykänen
HEAD OF TENNIS AT VIERUMÄKI
Players gave great feedback about the system, and the challenge feature made the tournaments feel fair. No disputes, no unnecessary stress for players or the crowd. The human eye simply can’t match the precision of the system.
Mikko Henriksson
CHAIRMAN OF KARIHAARA TENNIS CLUB
Both me and the club had been interested in getting the Zenniz system for years. At the end of 2024, I contacted Zenniz, and started asking around and involving people here. Very quickly, we had about twenty people on board. The enthusiasm came from many different reasons - from the ability to review line calls to the data and video features. Now in Kemi, every shot, every movement of players and the ball is tracked - shot by shot.
Linus Eriksson
FOUNDER OF BASLINJEN.COM
The system helps defuse tension in match situations regarding line calling decisions and also contributes extra energy during training sessions. The built-in training modules add a few extra percentage points of motivation to beat one’s own records, resulting in an even better and more positive training environment.
Juho Paukku
FORMER PROFESSIONAL PLAYER
Zenniz performs reliably during matches, helping with line calls and showing the spectators the situation clearly. Its user-friendly design ensures minimal setup time and effortless operation.
