Cardinal Square is building AI-native schools, starting unaccredited with an after-school writing class before building full, accredited schools. We think education is going to look very different in a few years; not a world without teachers, but one where great educators and AI work side by side to deliver personalized education to every student. The company was founded by Bryan Hong; Jai Pal.
It is part of YC Fall 2026. It is based in San Francisco, CA, USA.
