Full-service presell launch campaigns for course marketplace instructors

Course marketplace instructors don't own their audience. The platform holds the student relationship — pricing, contact details, and future access all sit with someone else.

The answer isn't to move your existing courses somewhere new and hope students follow. It's to find out what your audience actually wants next, build a direct relationship with them, and collect payment for it before you've built anything. Composer Forge was funded this way — presold to my own course marketplace audience before a single lesson was recorded.

I run this process end to end for other course creators — from identifying the right offer, to building an owned audience, to a full presell campaign. The offer could be a course, a membership, a tool, a service, or something else entirely. The validation process tells you which.
