Classkick

Classkick is a Kapor Capital-backed platform that enhances student learning through feedback. Research shows feedback to students is the number 1 driver of learning, increasing annual student learning outcomes 200%. Teachers not only struggle with the quantity and quality of personalized feedback, but collaboration between students is also stifled. Just like Slack has opened up communication in the workplace and on teams, Classkick increases feedback and collaboration inside and outside the classroom.
