Udemy is a global online learning marketplace that connects instructors and learners. Founded in 2010 by Eren Bali, Gagan Biyani, and Oktay Çaglar, it operates out of San Francisco and has grown to serve tens of millions of learners worldwide.

The platform allows experts to create and publish courses on nearly any topic—from software development, data science, business, and design to personal‑enrichment, wellness, language, photography, and more.

Learners can purchase courses individually (many on discount) or access collections via “Udemy for Business” or “Udemy for Government,” which offer curated catalogues, analytics, and enterprise management tools.
