Yermie Cohen
Yermie Cohen is the founder and CEO of Memorang, an AI stack for education that lets organizations build, launch, and scale custom learning and assessment content. A med student who arrived at UCLA from MIT with biology and mechanical-engineering degrees, he was buried in flashcards and frustrated by tools that were either too simple or too expensive, so he built his own. Memorang began as a free spaced-repetition study app in 2013 and has since become a platform pitched at publishers, institutions, and professional organizations who want to turn expertise into AI-driven courses, quizzes, and exams with humans kept in the loop.
Valentin Ruest
Valentin Ruest is the co-founder and US co-CEO of Classtime, a Zurich-born edtech company building a formative and summative assessment platform used by educators and learners in more than 90 countries. A University of St. Gallen and Harvard-trained economist who once ran mortgages at a Swiss fintech, he traded banking for classrooms, splitting his life between Santa Barbara and Zurich while teaching personal finance in public schools and arguing that software should help teachers decide, not decide for them.
