The tech looks cool.

But it does seem that your platform ingests video content without the permission of the person who creates these videos? The value of your platform is driven by the people creating the videos. You say that you do revenue sharing, and that you have done 5 partnerships. But you have 400 courses, so what about the other 395?

Putting it as kindly as I can: this is ethically fraught. Really, did nobody in the room point this out? You do not come off looking like a partner here.

You need to make this opt-in, not opt-out, and specify revenue sharing terms up front. Those terms need to be generous. The people who produce video content are producing the majority of your product's value. Opt-out, of an ambiguous revenue sharing agreement, is not enough.
