Serving thousands of schools and daycare centres across Europe, the company has already taken strides towards its vision of a world in which technology enables everyone to benefit from the best possible education. 2024 funding and the acquisition of FoxEducation that same year will enable the company to accelerate international expansion and scale its products, all with the aim of becoming a first-choice partner for educational institutions across Europe.
