Joe Liemandt is a software entrepreneur turned education reformer who left Stanford in 1989 to found Trilogy, a highly profitable private software company, before pivoting to transforming K-12 learning. In this episode, Joe shares how he transitioned from leading a global software enterprise to becoming principal of Alpha School, where his focus is building a mastery-based, individualized education model that leverages AI as the missing infrastructure for large-scale change. He details the shortcomings of traditional K-12 education, explains how Alpha replaces conventional seat time with focused academics, and outlines the role of AI tutors and human coaches in helping students accelerate through material. Joe also discusses early results, the data-driven systems that track progress, and his ambitious plan to reach a billion children in the next 20 years by combining cutting-edge technology with proven learning science.
