The first version of a course should solve one painful problem for one specific person. It should not be a 40-video curriculum.
A useful minimum version might be:
That is enough to test whether the promise is real.
The larger course comes later, after you have evidence. Your first students reveal which questions deserve a full module, which examples actually help, and where the transformation breaks down. Building those lessons in advance is mostly guesswork.
This is also why I prefer keeping fixed costs low during validation. A $99/month platform costs $1,188 per year before demand is proven. A commission-only option such as iLoquio at $0/month and 5% per transaction keeps the cost attached to revenue while you learn. It is not the right fit for every mature business, but it is a rational structure for a first pilot.
The smallest version is not a compromise. It is the fastest way to discover what the real product is.
What did your first version include, and what did you remove later?
