| klassroom | Klassroom provides a platform for remote learning, video-conferencing, and homework management in an intuitive format for parents and educators. Klassroom caters specifically to educator needs while offering the level of engagement and ease-of-use found in the most widely used online social platforms. When a teacher starts to use the app in oneclassroom, other teachers in the school join in very quickly and easily. Teachers can create a new class in just minutes, and they invite parents to access posts in the class feed including announcements, homework, videos, pictures of activities, polls, events, documents, and more.Klassroom’s level of parent engagement is outstanding: more than 90% are monthly active users. Parents can react to posts, contact the teacher for appointments, or initiate private conversations using tools that are designed to strengthen parent-teacher relationships while protecting the teacher’s time. Klassroom can translate all posts and private messages between parent and teacher into 100 different languages, and Klassroom can also accommodate the visually impaired. Every parent or guardian can be involved — even across multiple households.Klassroom co-founders Frank-David Cohen and Damien Rottemberg have been friends since childhood and planned that one day they would build something together to make a positive difference in the world. That opportunity came in 2016 when both were divorced dads who found themselves distanced from the education of their children and wanting to be better connected.In Paris and New York respectively, Frank-David and Damien provided the first Klassroom app prototype to the teachers of their young children. The result was the same on both sides of the Atlantic: enthusiastic adoption by the teacher and a 95% parent view rate of all classroom communication.By listening closely to teachers’ needs, Klassroom has maintained a nearly perfect satisfaction rating. The Klassroom app is now used in thousands of English, French and Spanish-speaking classrooms across 30 countries. | $400K | Pre-Seed | Sep 30, 2016 |  |
