Riiid: Riiid develops AI-powered adaptive learning and test preparation technology, most notably the Santa TOEIC app, which uses reinforcement learning and knowledge tracing algorithms to personalise English proficiency test preparation for individual learners based on their demonstrated strengths and weaknesses. 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. The company has expanded its AI tutoring technology beyond TOEIC into other standardised test preparation and enterprise training applications.\n\nRiiid competes in the AI education market against Duolingo, Khan Academy, and Korean education technology companies including Classting and Mathpresso. 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. Physics Wallah AI: Physics Wallah is an edtech company built around accessible, affordable online education for Indian students preparing for JEE, NEET, and other competitive examinations, with AI-driven personalization features increasingly embedded across its content delivery and doubt resolution systems. The platform combines live and recorded lecture content from subject matter experts with AI-powered doubt resolution, performance analytics, and adaptive practice.\n\nThe company raised approximately $100M in Series B funding, achieving unicorn status at a valuation of $1.1B, and has grown to serve tens of millions of registered students. Physics Wallah has expanded beyond its original video lecture model to include offline center franchises, AI tutoring tools, and a broader K-12 curriculum offering.\n\nPhysics Wallah's rise from a single YouTube channel to a billion-dollar education platform reflects the massive unmet demand for high-quality, affordable exam preparation content in India. The company's increasing investment in AI personalization and doubt resolution positions it to extend beyond asynchronous content into responsive, interactive learning experiences at a price point accessible to students across India's economic spectrum.

Riiid got there first, launching in 2014 — that's 6 years of extra runway. Physics Wallah AI didn't arrive until 2020. In AI, that kind of head start means more training data, deeper customer relationships, and a bigger talent moat.

Riiid has about 100-500 employees; Physics Wallah AI has about 1000+. A bigger team usually means more revenue or heavier VC backing, but in AI, small teams can build at massive scale.

Yes — they're direct rivals. Both Riiid and Physics Wallah AI compete in AI Education, targeting many of the same buyers. If you're evaluating one, you should be looking at the other.
