I accidentally signed up for a course called "project proposal" thinking it was about submitting research to conferences, but it was actually about pitching ideas to VCs. Rocked my world.
Although it wasn't quite what I imagine they were hoping for, I dropped out after that semester and have spent the last 5 years happily entrenched in startups.
My best guess would be that they do not know the option exists and/or they do not believe they can do it. It does and they can.
So spread the word!
