I had a similar experience with putting a course on udemy. Made about $4k in the first month and $400-500 per month after. Completely passive income with no advertising and just word of mouth
Very impressive, nice work. What was the course and would you recommend Udemy?
Udemy is alright. The profit sharing rules cut you out of a lot unless you actively market, and they’re constantly on sale so you don’t make much per purchase. But it makes up for it in sheer volume. You also need to stand out amongst a lot of content because there’s a very low barrier for entry to meet the requirements to create a course.
