Judging by the current landscape, the real goldmine business these days seems to be the so-called “teachers’ teacher”—someone who sells courses taught by others. There are so many new startups emerging that it’s hard to even list them all. Basically, it appears to be a model where individuals with some financial success are contacted to record videos, and the platform takes a cut of the course revenue. This ecosystem likely works because the course-selling business itself has almost zero marginal cost. It feels like everyone is aggressively promoting through referrals and word-of-mouth. When asked why anyone would kill the golden goose, the answer is simple: 1. Over 90% of students know they’ll never be as good as the instructor anyway. 2. Even if there are 10% with real potential, the true core insights—the real “honey”—are never disclosed. For these two reasons, they feel no hesitation in selling these courses freely.
