Level is a learning technology company dedicated to helping students build real academic and life skills with confidence and joy. We combine proven curriculum principles with world class interactive design to make meaningful practice something students want to come back to, not something they struggle through.
We support what teachers, schools, and parents are already doing by increasing student engagement with high quality, standards aligned practice that reinforces classroom learning. That’s why we’re building:
For students: Rewarding and motivating learning experiences that meet students where they are to build real academic proficiency.
For educators: Tools that fit naturally into instruction and help students stay engaged while reducing teacher workload.
For parents: Activities that help your kid catch up or get ahead, build confidence, and minimize homework battles, whether learning at school or at home.
We are committed to helping every person maximize their potential and live a life of meaning. It’s a difficult problem that requires brilliant people and tremendous effort over time.
