About Brilliant Worldwide, Inc.
Brilliant Worldwide, Inc. is an online education company founded in 2012 and headquartered in San Francisco, California. The platform was co-founded by Sue Khim, who serves as CEO, and focuses on teaching STEM subjects through interactive problem-solving and guided discovery rather than passive video lectures.
Brilliant offers courses in mathematics, science, computer science, data analysis, and programming, structured as bite-sized interactive lessons accessible via web and mobile applications. The platform operates on a freemium model, providing a limited set of free content while charging a subscription fee for full access. Its approach emphasizes active learning, requiring users to work through problems step by step rather than simply watching instructional content.
The company raised a Series A round and subsequently a Series B, with total disclosed funding reported at approximately $15.5 million from investors including Y Combinator and other venture backers. Brilliant has grown to serve millions of registered users globally, with its subscriber base spanning students, professionals, and adult learners seeking to build quantitative skills.
