Letuin

What Letuin does

Letuin (렛유인, 주식회사 렛유인에듀) is a Seoul-based private education company founded around 2013 that operates a vertically specialized job-preparation platform for science and engineering graduates in South Korea. The platform delivers industry-specific curriculum, mock examinations, consulting, and community support targeting employment at Korean conglomerates — primarily Samsung Electronics, SK Hynix, Hyundai Motor Group, LG Energy Solution, and Samsung Display — across six industry verticals: semiconductor, secondary battery, automotive/mobility, display, pharmaceutical/biotech, and defense. Core instructional assets are former HR executives from Samsung/Hyundai/LS and current engineers from major conglomerates, which the company treats as its primary differentiation. The platform is accessed primarily through letuin.com and the Egongmoya (이공모야) community sub-brand; additional distribution includes Naver Smart Store for books, university MOUs for campus programs, and a dedicated LetuinEdu B2B channel for corporate and government training.

The underlying technology comprises an online video platform with VOD and live streaming, an interactive LMS for K-Digital government-subsidized training, online mock-exam systems for Samsung GSAT and SK Hynix SKCT, and community features including real-time chat, peer mentoring, and skill-spec tracking. Layered AI features include the Career Path AI chatbot for course recommendation and an AI-driven Semiconductor Roadmap. Letuin monetizes through a multi-stream model: individual VOD course purchases (20,000–189,000 KRW), the L-PASS monthly subscription (19,900 KRW/month) with discount coupons, premium 200% Refund Free-Pass packages with hiring-contingent refunds, 1:1 consulting (300,000 KRW per two-hour session), published books, K-Digital government-subsidized training (90% state subsidy), and B2B corporate training. The company reports 38,487 cumulative successful graduate placements (2015–2023), 110,150 course reviews, and 5,076 cumulative semiconductor lab participants at the Ajou University partnership site.

Letuin operates as a self-funded private stock company (주식회사) with 51–100 employees, headquartered in Seoul's Gangnam district across two campuses, with no disclosed external funding, no M&A history, and no current IPO plans. Recent strategic activity has centered on product expansion (Engineering Data Lab launched March 2025), AI-related MOUs with MindCode (2024) and Magic École (2023), university partnerships for talent development (Daelim University, Kyonggi University), and recognition as a Yes24 bestseller and Gangnam-gu outstanding job-creating company.
