Back-end Engineer

Can AI solve the education inequality issues of today? What if the AI tutor can grade my English speaking and writing skills and provide an adaptive and customized curriculum at a low cost? 

Databank started with a vision to bridge the education gap and bring about social impact in the global education industry. In 2019, Databank launched the first product, TestGlider, the AI TOEFL Tutor, previously known as TOEFLBANK. TestGlider is the world's first AIEd solution that evaluates open-ended responses and provides adaptive education through machine learning and deep learning technology. In two years, TestGlider has become a global TOEFL platform with over 700,000 users from 196 countries. Within a month after the launch of the paid version, purchases were made in over 100 countries, witnessing a global product-market fit. Databank is the fastest growing start-up among Korean EdTech start-ups. Databank raised $2.7m in series A funding in April, seeing the corporate value growing by 1300 times in 2 years.

Databank, equipped with specific plans, execution, and technology for the upcoming Series B round in 2022, is the next unicorn of 2025.
