About Go Potty®

Go Potty® is a social enterprise with a mission: to reduce the time children spend in diapers 🌍. While children in the 1940s were potty trained around the age of one, this is now only achieved around age three. Early potty training has many benefits for a child’s well-being and the planet! With Go Potty® software, we support parents, childcare organizations and municipalities with a positive and effective approach to potty training. For the little ones of today and the planet of tomorrow.
