What Team Monolith (CODLE) does

Team Monolith, operating commercially as CODLE, is a Seoul-based AI education company founded in October 2021 that builds Codle, an AI-powered all-in-one classroom operating system for K-12 schools. The platform serves 800+ schools across 11 countries with 1,700+ certified teachers and approximately 190,000 students learning monthly, covering lesson preparation, real-time classroom monitoring, assessment, and feedback across 12 subject areas and 6 grade levels. The company's proprietary AI talent modeling technology is trained on 1.16 million hours of actual classroom instruction data and differentiates through process-centered evaluation rather than score-based assessment.

Codle's product surface includes generative AI for lesson content and assessment creation, real-time progress tracking with automated teacher intervention, AI grading of open-ended questions with rubric generation, and a Socratic-method conversational tutor called Socrates Light. The company has expanded its product line with an AI Hackathon Operation Service and is developing talent modeling technology intended to extend into university admissions and recruitment markets. Co-developed AI digital textbooks with Samyang Media carry official certification.

Revenue is generated through B2B subscriptions sold to schools, educational offices (교육청), and government institutions, with international expansion progressing via direct enterprise sales and a channel partnership with US-based BootUp PD. The company achieved first profitability in 2024 alongside 700% annual revenue growth, reached approximately 2.8 billion KRW in H1 2025 revenue, and was founded with seed capital from Mashup Angels in 2022. Operates with a deliberately small team (~11 employees) under a 'small team x high density = big results' philosophy.

Core offering

Team Monolith develops and operates Codle, an AI-powered classroom operating system for K-12 schools that combines lesson preparation, real-time classroom monitoring, and assessment/feedback on a single integrated platform.

Codle is an all-in-one solution covering lesson preparation, real-time classroom management, evaluation and feedback, with AI-powered automated grading and content generation. The portfolio includes Socrates Light for conversational AI tutoring, an AI Hackathon Operation Service for school hackathons, and extends through partnerships like Roboraisen for robotics integration and Samyang Media for digital textbooks.
