Company Overview

PrepMaster Inc. is a Seoul-based AI-powered EdTech venture founded in 2023, specializing in high-stakes relational reasoning assessment. Leveraging 23 years of domain expertise in SSAT preparation, we have developed a proprietary 55-Logic Taxonomy and 75-Trap Matrix — deployed as dual-constraint conditions within a 4-Layer AI generation and validation pipeline. Our technology automates the creation and verification of premium reasoning content at a quality threshold no general-purpose LLM can replicate, targeting the global high-stakes assessment market that remains structurally untapped by Big Tech.

PrepMaster's mission is not to replace subject-matter experts with AI, but to transform 23 years of tacit domain knowledge into formalized, AI-readable logic — realizing a human–AI collaboration model where precision and expertise compound together.
