Zenniz

Zenniz, a Helsinki-based company founded in 2012 by Juha Toivanen and Vesa Maani, is positioned at the intersection of sports and technology, offering a comprehensive smart court system for the tennis market. The firm targets a broad clientele, including tennis clubs, academies, coaches, tournament organizers, and individual players of all levels. Zenniz's business model involves selling its hardware system to facilities, estimated at approximately $10,000 per court, and then generating recurring revenue through a consumer-focused subscription, Zenniz Premium, which unlocks AI-powered analytics and other advanced features. This dual B2B and B2C approach allows clubs to upgrade their courts and create new revenue streams through pay-per-use models or membership upgrades, while players gain access to performance-enhancing tools.

The company's core product is an end-to-end smart court system that transforms any standard tennis court. A key technological differentiator is its patented Dual Tracking technology, which integrates both audio triangulation from 30 court-mounted sensors and visual data from four high-quality cameras to precisely track the ball and player movements. This system facilitates a suite of features including ITF Silver Level Certified electronic line calling, real-time performance statistics (like serve speed and shot placement), video recording with highlights, and interactive training drills. Data and video are accessible through a mobile app and can be shared on a social platform, fostering community engagement and providing detailed analysis for player development. The on-court experience is enhanced by a smart net post with LED panels that display real-time feedback and scores.

Zenniz has steadily progressed, securing its first seed funding in 2012 and participating in accelerator programs. A significant milestone was winning the 'Overseas Innovation' category at the TIA Tennis Innovation Awards in the UK in 2017. The company has attracted a total of $4.08M in funding over several rounds, with a notable €2 million ($2.18M) seed round in early 2025 led by Butterfly Ventures and Superhero Capital. This capital is fueling expansion into the U.S. and key European markets, building on its presence in nearly 20 countries. The company's credibility is further solidified by its technology's approval from the International Tennis Federation (ITF) for use in competitive play and a strategic partnership with the prestigious Mouratoglou Academy.
