Is this common knowledge? I've seen it empirically but I don't know how much is that a widespread feeling. (Not being snark or sarcastic).
I'm not aware of other recent high-profile examples, though I would be interested in learning about them.
Good business teams tend to be good in the details, which leads to them struggling to find willing audiences.
A few more for real scam connoisseur's:
Stacy Spikes/MoviePass (70M+ for selling dollars at a penny; outstanding growth and metrics though, if only the "lose on every sale but make it up in volume" stance ever worked ¯\_(ツ)_/¯)
Steve Newcomb/famo.us (30M+ seed funding for what was essentially a shitty JS library)
Bill Nguyen/Color (40m+ seed funding for a photo app with no extra features; you know, like the one that comes for free in your phone ..., but with ads, ... also a social network? no one really knew, not even them)
