We're building the future of tennis - one Smart Tennis Court at a time Zenniz makes tennis courts intelligent. Our system delivers electronic line calling, real-time match analysis, video tools, and gamified drills by turning sensor data and video into insights that help players, coaches, and clubs perform at their best. We are used on courts around the world, and we are growing fast. This year, we are expanding our customer support operation from Finland into North America and beyond. This hire is where that starts.
