History

Co-founder Jongheun ‘Ray’ Lee first came up with the idea of QANDA during his freshman year in college. While he was tutoring to earn money, Lee realized that the quality of education a student receives is greatly based on their location. Lee saw his K-12 students were regularly asking similar questions and realized that these questions were from a pre-selected number of textbooks currently being used in schools. He decided to team up with his high school friend, Yongjae ‘Jake’ Lee to build a platform whereby, one uses a mobile app to scan and submit questions, and students can ask and receive detailed responses. Lee's school friends, Wonguk Jung and Hojae Jeong, joined the team.[5][6]

In June 2015, Mathpresso, Inc. was founded in Seoul, South Korea.

In January 2016, Mathpresso's first product QANDA was launched. It supported a Q&A feature between students and tutors.[7]

In October 2017, QANDA introduced an AI-based search capability that permitted users to search for answers in seconds.[7]

In June 2021, QANDA raised $50 million in series C funding.[8]

In November 2021, QANDA secured a strategic investment from Google.[9]

Since its inception, it has received backing in Series C funding from investors namely Google, Yellowdog, GGV Capital, Goodwater Capital, KDB, and SKS Private Equity with participation from SoftBank Ventures Asia, Legend Capital, Mirae Asset Venture Investment, and Smilegate Investment.[9][10] The total cumulative investment is about 122 million dollars.[11]
