About Primer

Fixing our K-12 education system is a civilizationally-important problem. We believe that all of our problems — including the ones that dominate the headlines — are downstream of education.We have a simple thesis on how to solve it: empower 1,000's of educators to launch microschools in their communities.We believe the historical tradeoff between price (tuition) and quality is a false dichotomy.PrimerOS automates and eliminates much of the costs of traditional schools. Microschools have a structural advantage — asset-light real estate — which means much lower capex and opex. You put it together, and you get something that's never existed before: a world-class education that's accessible to normal American families and can rapidly scale.Role overview
