Founded in 2023 by entrepreneurs from an English education startup and a developer from Seoul National University, Setawon is revolutionizing English education based on AI technology. Successfully secured 1 billion Seed investment led by Strong Ventures and The Ventures, and was selected for the 1.5 billion deep-tech TIPS support project in Korea.
Based on excellent colleagues and an agile culture, Setawon is rapidly growing towards the global market by developing Langflix, a language education service based on world-class educational AI models and video content.
With Langflix, all you need to do is input the URL of your desired YouTube video, and a learning curriculum tailored to your interests and preferences will be generated. We provide the industry’s only four-axis shadowing feedback (phoneme, stress, speed, rhythm) based on Deep Tech TIPS, supporting Netflix, YouTube, and short-form videos.
Since monetization in January 2026, we have been growing twice each month and have reached second place in the app store education chart. Ultimately, we aim to be the 'TikTok of English learning,' allowing users to learn English in a fun and effective way through video-based content every day.
We are looking for a Marketing Manager (Growth Marketing Lead) to expand Langflix's market share in Korea and participate in global expansion.
