I Hate Flying Bugs

What I Hate Flying Bugs does

I Hate Flying Bugs Inc. (아이헤이트플라잉버그스(주)) is a South Korean EdTech company founded in February 2012 and headquartered in Seoul. The company develops AI-powered personalized learning management platforms serving both private consumers (B2C) through Mildang PT and public K-12 institutions (B2G) through School PT. Its core technology stack centers on a proprietary Deep Knowledge Tracing (DKT) algorithm with over 90% accuracy in predicting learner weak points, an Active Multi-Agent AI system for real-time student concentration monitoring, and integrated large language model capabilities, all built upon a proprietary dataset of 1.3 billion learning data points accumulated over more than 12 years. Mildang PT delivers 1:1 online tutoring for students grades 3-12 in English, mathematics, and Korean, combining AI-generated personalized curricula with high-quality video lectures from Daechi-dong instructors and full-time "ontact" teachers, achieving a 92% daily completion rate. School PT serves public schools with AI Digital Textbook content, real-time monitoring dashboards, knowledge mapping, and after-school programs that have accumulated over 200,000 participants, with reported 93% completion rates. The company also operates B2B channel partnerships through co-branded products MegaPT (with MegaStudy) and Neungyule PT (with NE Neungyule), and an EduWill partnership signed April 2025.

The business model operates across three primary revenue streams: (1) B2C monthly subscriptions for Mildang PT sold direct-to-consumer nationwide with self-serve onboarding; (2) B2G multi-year subscription contracts for School PT sold directly to public schools and government education programs through negotiated enterprise pricing; and (3) B2B licensing/co-development revenue from channel partners and publishers including Jihaksa, Kyohaksa, and MiraeN. Pricing for Mildang PT is positioned as affordable relative to traditional Korean private tutoring, while School PT pricing is negotiable per school budget with multi-year contracts including standard classroom and after-school packages. The company is venture capital-backed, having raised approximately KRW 95.4 billion (~$70M USD) cumulatively across six rounds from 2019 to 2025, with Eugene Asset Management, SV Investment Corp, and KDB Industrial Bank among named investors. IHFB holds pre-unicorn status from the Korean Ministry of SMEs and Startups (2023) and has been selected by KERIS as the AI Digital Textbook prototype developer for middle school math (2023) and elementary/middle school science (2024). The company is pursuing global expansion into Latin America, Southeast Asia, and Europe via B2G and B2B licensing models, with MWC 2026 marking its international debut, and was selected for the Ministry's Scale-up TIPS program in December 2025 to develop Proactive AI technology targeting the approximately $3 trillion global education market.

Direct peers
