Brilliant Worldwide, Inc. (Brilliant.org)
A San Francisco consumer-learning company that teaches math, science, computer science and data through short, interactive problem-solving lessons rather than video. Brilliant began in 2012 as an online community of challenging problems for talented students, turned into a paid course subscription for curious adults, grew through sponsorships on science YouTube channels, and from 2022–23 rebuilt itself as a mobile-first, gamified, "learn by doing" app in the mould of Duolingo for STEM.
