What Brilliant.org does

Brilliant Worldwide, Inc., operating as Brilliant.org, is a private San Francisco–based education technology company founded in 2012 that delivers interactive STEM learning experiences to more than 10 million learners worldwide through a freemium subscription platform accessible via web, iOS, and Android. The platform offers 40+ courses spanning foundational and advanced math, computer science and Python, data analysis, and science, built around visual and interactive problem-solving rather than video lectures, with curriculum authored by educators from MIT, Harvard, Stanford, Cornell, and Caltech.

The company's core technology combines an interactive content infrastructure with Koji, an AI-powered personal tutor launched in 2024 that uses a third-party foundation model layered with Brilliant's proprietary pedagogy to see what learners are working on, generate visuals and problems on the fly, identify misconceptions, and drive a personalized practice engine. Complementary capabilities include voice input via third-party speech-to-text and a free Brilliant for Educators tier; the company also acquired interactive-video platform Hellosaurus in December 2022.

Brilliant monetizes primarily through consumer subscriptions: Premium at $20/month billed annually ($240) or $30/month, a Family Plan at $40/month for six seats, Group Plans for 3–50 people at roughly $11.33/month per seat, and Gift Plans. The customer base is horizontally distributed across K–12 and college students, homeschooling families, lifelong learners, parents, and teachers, with no enterprise anchor customers, and "hundreds of thousands" of paid subscribers per company disclosure. The business runs a product-led, self-serve distribution motion with word-of-mouth acceleration through the educator and homeschooling communities, supplemented by app-store presence and a MATHCOUNTS partnership.
