Hanyang University Lee Jong-heun (School of Electric Engineering) alumnus is currently co-president of the education technology startup, Mathpresso. The company's application QUANDA has recently been catching the eye of many. Lee and co-president Lee Yong-jae introduced their success strategy for QUANDA in an interview with Hankook Ilbo. 

QUANDA is an application that solves and explains problems. When student users post photos of math problems that they do not know, teachers repost answers and explanations for them. An average of 500 questions are posted a day, and the service is being used in around 50 countries with an average of 8.6 million users. 

QUANDA was created from the tutoring experience of Lee and co-president Lee Yong-jae, when they noticed the problem of education inequality. Lee Yong-jae mentioned, "students that were learning from Lee Jong-heun, co-president, would always send pictures of math problems to him. I noticed that it could turn into something." They created the Mathpresso during the second semester of their senior year of university, learned to program, and developed the QUANDA app that solves math and science problems. The app was launched in January 2016.

When the AI search service was first used, users also skyrocketed. The success strategies of QUANDA are an easy way of asking and answering problems through photographs, and the powerful AI search engine that even detects the math formula. Around 20 thousand questions are uploaded every day, just within Korea. This is similar to the number of pictures that are uploaded on an SNS channel. Lee mentioned that, "half of all middle/high school students are using QUANDA every day, just like an English-Korean Dictionary." The app is now part of school supplies."

Overseas service is another success strategy of QUANDA. They started preparing for the overseas service in 2018, and began the service in Japan. Starting from 2019, they created the QUANDA app in Vietnamese, Indonesian, and Thai, while English and Spanish apps were launched last year.

Their goal is to become an education application that is used the most in Asia. Following this goal, they are also planning to start a subscription service that can be used when making payments, around this May or June. They are also developing a community service that will be launched around May, which will serve as a communication platform between students. Lee mentioned, "as much as we are a company that innovates digitialized education, we believe that community innovation is equally important."

Meanwhile, Mathpresso, that was co-founded by alumnus Lee Jong-heun, was selected as "HYU-Unicorn Club" last year. Accordingly, Mathpresso will receive scale-up infrastructure through Hanyang University's customized business start-up support system.
