Remind (formerly Remind101) is a private mobile messaging platform that enables teachers to send Reminders to students and parents via text and email. The platform has over 10 million users and sends over 65 million messages per month. As of February 2014, 15% of the K-12 teacher population in the U.S used Remind. Remind was founded in 2011 by brothers Brett and David Kopf to help bridge the communication gap in primary education. Brett Kopf was diagnosed with attention deficit disorder and dyslexia while he was still in school and credits his brother David setting up a system where school faculty could Remind him of an upcoming test played a part in his success in school. The two decided to make the system into a company and became part of the first class at the Imagine K12 incubator in Palo Alto, CA, where all startups must focus on improving education. The brothers incorporated feedback from hundreds of teachers, who they interviewed to develop a platform that would work for them. The founders described themselves as "teacher obsessed" and focus on building the product for teachers.
