Brilliant

Brilliant is an interactive learning platform founded in 2012 and headquartered in San Francisco, California. It offers over 100 guided courses in mathematics, computer science, data analysis, coding, AI, and science and engineering. Brilliant's approach is built around active problem solving rather than passive video consumption — lessons present concepts through interactive puzzles and challenges that build intuition step by step. The platform serves over 10 million learners worldwide, from students to working professionals and lifelong learners. Courses are crafted by educators and scientists from top institutions. Brilliant operates on a freemium subscription model and has raised approximately $94 million in funding.
