Zenniz Brings Smart Court Tech to College Tennis via ITA

College tennis has a new official technology partner. The Intercollegiate Tennis Association has named Zenniz an Official All-in-One Smart Tennis Court System of the ITA, approving the Finnish company's electronic line-calling system for indoor use in singles and doubles play, both officiated and unofficiated. ITA CEO David Mullins pointed to the system's debut at the 2026 ITA Division III Women's National Team Indoor Championships as proof of concept. "Technologies that enhance the student-athlete experience, improve competitive integrity, and provide valuable performance insights will play an increasingly important role in our sport," Mullins said, adding that the ITA looks forward to helping more college programs access the system. The partnership lands at a moment when Zenniz is scaling fast, well beyond college courts, having just opened a U.S. headquarters outside Atlanta on the back of what the company describes as serious momentum in the American market. "College tennis has long deserved better technology on and off the court," said Zenniz Managing Director Santtu Leskinen, calling the ITA deal a chance to give athletes and coaches the tools to compete fairly and train more efficiently.

What the System Actually Does

Zenniz's flagship product, the Zenniz Gen2, combines electronic line-calling, on-court analytics, and video streaming into a single integrated system built around four off-the-shelf cameras and thirty custom sound sensors for ball tracking, plus a central unit with screens for accessing the tech on court. A single-court installation runs about $13,500 up front, with a $70 monthly fee covering data storage and maintenance. Zenniz has recently added a lighter, camera-only version called Zenniz Lite, priced around $2,000 plus $30 a month, aimed at clubs that want video tools without the full sensor-based line-calling setup. The system's line-calling technology holds ITF Silver Level certification from World Tennis, one tier below the professional gold standard, a distinction Zenniz shares with only one other provider, PlayReplay.

A Business Built Around Club Monetization

Rather than selling the system as a standalone product, Zenniz has built its go-to-market around helping clubs make money from it. "That's been the nut we are wanting to crack with the clubs," Leskinen said, describing revenue-share arrangements tied to Zenniz's premium consumer app, priced at $14.90 a month, and upticks in court rental pricing as the two most common paths clubs take. That model has helped push U.S. installations to 140 courts across 30 facilities, a little under a third of Zenniz's roughly 500 installations worldwide, making the U.S. the company's largest single market. "We're seeing more and more partnerships grow here, and more and more facilities acquire our tech," Leskinen said of the broader U.S. push.

Zenniz's courtside unit prompts players to "hit to start," the on-court entry point for the company's electronic line-calling, analytics, and streaming system.

Why Atlanta

Zenniz settled on Atlanta as its U.S. base largely because of the city's tennis culture, which is home to a recreational league network with more than 100,000 active players and organizations including the Atlanta Lawn Tennis Association and USTA Atlanta. "Atlanta offers an incredibly passionate, thriving network of players and facilities, making it the absolute perfect launchpad for the growth of Zenniz," Leskinen said. The city is also home to INTENNSE, a new professional, team-based tennis league that plays out of Assembly Studios, which recently partnered with Zenniz to integrate its smart-court training tools into player development. "Zenniz represents exactly what INTENNSE stands for, which is bringing the best technology in tennis to our players," said INTENNSE CEO Charles Allen. "The kind of insights that used to appear only in tour-level analysis are now part of our daily training, accelerating how our players learn, adapt, and grow." Zenniz has also been piloting its technology at the Rome Tennis Center in northwest Georgia, giving the company multiple footholds in the state beyond its Sandy Springs headquarters.

Funding and the Road Ahead

Zenniz closed a $6 million funding round earlier this year, backed by Finnish investors Butterfly Ventures and Superhero Capital along with French firm Seventure Partners, and the company plans to put that capital toward further installations, product development, and hiring. Co-founder Eero Kuusi currently leads the company, whose technology is now installed in more than 25 countries and remains ITF-certified for club-level international tournaments. The Atlanta office currently runs lean, with Leskinen and an installation project lead on-site alongside two remote sales representatives, out of roughly 30 full-time staff companywide. Leskinen has said the plan is to recruit aggressively from Atlanta's sports tech talent pool as the U.S. business grows. Between the ITA partnership, the INTENNSE deal, and the fresh funding, Zenniz's expansion into American tennis looks less like a single market entry and more like the build-out of a long-term U.S. footprint.
