> I wasn't able to come up with people who claim that they were actually scammed, i.e. paid for a product that wasn't delivered or made an investment into something that doesn't exist.
I'm gonna ask the other way around. Name one successful product by the CEO that has reached mass production and you can get it right now.
Well, AppGyver was real. SAP bought it, it's now called SAP Build.
Don't know how successful it was/is as a product though.
That’s ridiculous, neither making your first product nor failing is scamming.
In this particular case you can buy motorbikes and sport cars made using electric motors from the same company that makes this battery. So at least 1 real product that I know of.
