We like to say we are the "Mathletics of science", in that we have a similar business model. Mathletics, an Australian program by 3P Learning, has been hugely successful in bringing online maths to schools across the country (and globe) and we want to do the same for STEM (Science, Technology, Engineering and Maths).
Ultimately, schools pay per student per year for access to the platform, and all its content.
