CLASSUM

Through a cloud-based platform where course members can connect via posts, lives sessions, chats, and unique interactions, CLASSUM offers seamless communication to enhance all learning environments, online or in-person. --- CLASSUM was founded in 2018 by Chaerin Lee and Youjin Choi, two female students at Korea Advanced Institute of Science and Technology (KAIST), to address the challenges they faced as learners. After only 3 years, CLASSUM is now used by over 3,700 institutions in 23 countries worldwide, and continues to break communication barriers and build learning environments that foster growth and collaboration. Users include institutions such as KAIST, Yonsei University, and Ewha Womans University, as well as global corporations including LG, Samsung Electronics, Shiseido, Hyundai, World Vision, and Prudential. Our goal is to bring learners and educators together in a space where they can communicate freely and comfortably. We want to create and expand spaces where healthy interactions and collaboration can take place naturally inside and outside the classroom. Learners can freely interact on CLASSUM, engaging in Q&A and discussions through text and other media that fit their communication needs in this digital age. Educators using CLASSUM to communicate with their students have experienced increased student engagement and reduced admin work. In April 2021, CLASSUM raised a $6M Series A led by Pearl Abyss Capital and Storm Ventures along with existing investors Big Basin Capital and Smilegate Investment. Our founder and CEO, Chaerin Lee, was recently recognized as a member of the Forbes 30 Under 30 Asia Class of 2021 for CLASSUM’s innovative approach to communication challenges in education. CLASSUM was also selected as one of GSV Cup back in 2020, which highlights inspiring EdTech and talent technology startups across six continents.
