Udemy

Udemy is an online course marketplace with a catalogue in the hundreds of thousands, built on an open publishing model: anyone can create a course, and the market rather than an editorial team decides what succeeds. That openness explains both the appeal and the criticism. The catalogue covers almost any topic, courses are frequently discounted to a small fraction of list price, and lifetime access means a purchase is a permanent reference rather than a rental. It also means quality varies enormously between instructors, and the discounting is aggressive enough that paying full price is almost always a mistake - the practical advice for any buyer is to wait for a sale, which arrive constantly. The learning model is self-paced pre-recorded video. That is the format's strength for reference and skill-specific learning, where you want a particular thing explained on your own schedule, and its weakness for anything requiring accountability - completion rates for self-paced courses are famously poor across the entire category, not just here. For anyone reading this as a founder rather than a learner, the more interesting part is the business. Udemy runs a consumer marketplace alongside Udemy Business, an enterprise subscription selling a curated subset of the catalogue to companies for employee training - a considerably higher-margin, more predictable business built on top of content the marketplace already produced. It is a clean example of a consumer platform finding its durable revenue in B2B. The comparisons split by purpose. Coursera and edX offer university-affiliated courses and credentials, which matters when the certificate needs to mean something to an employer. Maven runs live cohort-based courses where the deadlines and classmates do the work motivation cannot. Pluralsight and Frontend Masters are narrower and better vetted for technical skills. YouTube is free and unstructured. Skillshare targets creative work on a subscription. Choose Udemy for practical, self-directed skill building at a low price. Choose a cohort or a credential when finishing, or being able to prove you finished, is the point.
