Ask HN: Courses on non-tech startup/bootstrap aspects?

At the moment, it's very easy to find quality online courses/video tuts on almost everything tech. Even curriculums on what should be learnt and how.

However, when it comes to other aspects, i.e finance, business models, product, marketing, etc, there's nothing really 'structured', it's more about random posts or talks...

So, do you know of any courses that are not just about "how cool it is to start something" and general advise, but more down to technicalities, i.e what's CAC, LTV, CSat, NPC,...?

YC's Stanford course on "How to Start a Startup" was really interesting because it covers several topics, but I'd like to find something more specific.
