CodeHS is a K-12 computer science education platform that gives schools everything they need to teach coding: a browser-based coding environment, a full standards-aligned curriculum spanning elementary through AP, teacher tools for grading and progress tracking, professional development, and industry certifications. Founded in 2012 by two Stanford CS section leaders, Jeremy Keeshin and Zach Galant, it now reaches millions of students and thousands of schools, and in 2025 acquired the K-8 creative coding platform Tynker.
Jeremy Keeshin is the CEO and co-founder of CodeHS, the online platform that teaches computer science to millions of middle and high school students. A Stanford computer science graduate who cut his teeth as a section leader for the university's legendary intro programming courses, he launched CodeHS in 2012 with classmate Zach Galant to bring coding to schools that had never offered it. He wrote 'Read Write Code,' a friendly primer arguing that coding is the new literacy, and he still finds time to juggle, chase crosswords, and crack jokes rooted in his college days running the satirical paper The Stanford Flipside.
