I used to have a big trading course client. The biggest thing is to understand what their product life cycle looks like. So is the course targeting absolute beginners who aren’t familiar with trading or people taking it to the next level? Equally understanding how much it costs really helps you frame who the ICP is and the best way to target them.
A lot of info companies have a personal brand at the figurehead - that often will guide your ICP. A 45 year old man from Texas talking about quitting his job to trade stocks will attract a similar customer. A 22 year old with a lambo in Miami is not going to appeal to that same audience.
