CLASSUM is a growth and learning platform that emphasizes active communication, engagement, and knowledge sharing within an organization. It aims to foster a culture of continuous learning and professional development by transforming the way employees interact and collaborate.

Through a cloud-based platform, CLASSUM enables course members to connect via posts, live sessions, chats, and unique interactions, enhancing both online and in-person learning environments.

Established in 2018 by Chaerin Lee and Youjin Choi, two students from the Korea Advanced Institute of Science and Technology (KAIST), CLASSUM was designed to address the learning challenges they encountered. In just three years, it has been adopted by over 3,700 institutions across 23 countries, breaking down communication barriers and creating learning environments that encourage growth and collaboration. Its users range from educational institutions like KAIST, Yonsei University, and Ewha Womans University, to global corporations such as LG, Samsung Electronics, Shiseido, Hyundai, World Vision, and Prudential.

CLASSUM’s mission is to unite learners and educators in a space where they can communicate freely and comfortably. It aims to cultivate spaces where healthy interactions and collaboration can occur naturally, both inside and outside the classroom. On CLASSUM, learners can engage in Q&A and discussions through text and other media, meeting their communication needs in the digital age. Educators who use CLASSUM have reported increased student engagement and a reduction in administrative work.

In April 2021, CLASSUM secured a $6M Series A funding round led by Pearl Abyss Capital and Storm Ventures, with participation from existing investors Big Basin Capital and Smilegate Investment. Chaerin Lee, the founder and CEO, was recently acknowledged as a member of the Forbes 30 Under 30 Asia Class of 2021 for CLASSUM’s innovative approach to addressing communication challenges in education. In 2020, CLASSUM was chosen as one of the GSV Cup, a recognition that highlights inspiring EdTech and talent technology startups across six continents.
