What Is Synthesis?

Synthesis is an AI-powered math tutoring and collaborative problem-solving platform for children ages 8-14. It originated at Ad Astra, the experimental school on SpaceX's campus created for Elon Musk's children in 2014. Co-founder Josh Dahn built the curriculum there, then spun it out as Synthesis in 2020 to make it available to all children.

With 21,500+ students and subscriptions up 4.5 times year-over-year, Synthesis offers two products: Synthesis Tutor (AI-powered personalized math) and Synthesis Teams (game-based collaborative problem-solving).
