Udemy is an online learning platform that connects instructors with students, offering a wide variety of courses on subjects like programming, marketing, data science, business, IT, design, and personal development. The platform allows instructors to create and publish their courses, which students can purchase, providing the necessary tools and support for course development and marketing. Unlike many competitors, Udemy operates on a marketplace model, giving instructors the freedom to set their course content and pricing while Udemy takes a percentage of the sales. The goal of Udemy is to provide accessible and flexible education to a global audience, catering to individuals seeking personal growth, professionals looking to advance their careers, and companies investing in employee training.
