Zenniz raises €2M in latest funding round led by Butterfly Ventures and Superhero Capital

Zenniz, the world’s leading provider of smart tennis solutions, successfully completed a new €2 million funding round at the end of 2024. The round was led by Butterfly Ventures and Superhero Capital.

This funding will accelerate Zenniz’s ongoing global growth, particularly enabling expansion into the U.S. market and leading tennis nations in Europe. The company has already seen record-breaking sales in early 2025.

”First and foremost, we warmly welcome our new venture capital investors, Butterfly Ventures. Currently there is strong momentum in sports technology and Butterfly’s expertise in hardware startups, U.S. markets and background in tennis makes this a perfect match. Tennis as a sport is evolving into a more modern direction and our comprehensive all-in-one solution is resonating positively with customers”, commented Zenniz CEO Eero Kuusi.

“We are super excited to partner with Zenniz as they roll out in Europe and now the U.S. I’ve been playing competitively since was 5 and can’t imagine the current tennis world without a Zenniz platform for recreational, amateur, collegiate, and professional players. The platform not only brings a long needed social element to the game, but also couples highly accurate play and stroke metrics; Zenniz is revolutionizing the game of tennis”, mentioned Tanya Horowitz, Partner, Butterfly Ventures.

The recently completed funding round continues the company’s track record of attracting top-tier investors, including former ATP world No. 13 Jarkko Nieminen and former president of the European Business Angels Network Janne Jormalainen.

Alongside strong early-year unit sales, Zenniz has launched its Zenniz AI analytics services to enhance the Zenniz experience of players worldwide. This launch marks a significant expansion of Zenniz’s business model into the consumer product segment.
