The Seoul company builds AI models that predict which questions each student should practice to maximise test score improvement per unit of study time.\n\nThe company raised approximately $220 million including a Series D from investors including SoftBank Ventures Asia, Owl Ventures, and GoodWater Capital, reaching a valuation exceeding $1 billion. Riiid Santa TOEIC app has been used by millions of Korean learners preparing for the TOEIC English proficiency exam, which is a mandatory or strongly encouraged credential for employment at major Korean corporations.

Its reinforcement learning-based adaptive learning system, which optimises study sequences for individual score improvement rather than presenting content in a fixed curriculum order, represents a technically sophisticated approach to personalised learning that distinguishes it from content-first edtech platforms. The proven consumer use case in TOEIC preparation provides a revenue foundation and model validation that the company is extending into new learning domains.
