About Onuii
Onuii Inc., a South Korean educational technology firm established in 2016, is making significant strides in the private education market by targeting the digital-native Gen Z. The company's journey began when its CEO, nicknamed Jess, and CTO, Ira, met at a startup academy and conceived an on-demand academic support service. This initial concept evolved into their first product, the `` app, a real-time Q&A platform where students studying independently can receive immediate help from tutors.
The company's flagship service, ``, launched in June 2019, has been a primary driver of its rapid expansion. Seoltab is a one-on-one, non-face-to-face smart tutoring service conducted via tablet, connecting students with tutors from top-tier universities, often referred to as 'SKY' (Seoul National, Korea, and Yonsei Universities). The business model is centered on subscriptions for this personalized tutoring, which includes customized curricula, AI-powered learning management, and access to a vast library of digital textbooks and past exam questions. This approach has proven highly successful, with the company reporting a cumulative 530,000 paying subscribers and an average annual revenue growth of 230% over three years. By 2023, the service had surpassed 120 billion KRW in cumulative revenue.
Onuii's growth trajectory attracted significant investor confidence, culminating in a Series A funding round of approximately 14 billion KRW in November 2021, with participation from KB Investment, Strong Ventures, and others. Operating on a B2C model, the firm generates revenue from tutoring fees, which are comparable to traditional academy costs but bundle live tutoring, on-demand lectures, and digital materials. By focusing on creating an engaging and effective remote learning environment, Onuii aims to alleviate educational disparities, making elite tutoring accessible to students anywhere in Korea.
