Not sure why it's fair to have this discussion in this thread. Startups have risks and he is entitled to raise money. And he definitely has a history of building something big. To bring skepticism to someone's business without fair reason is simply not ok(I have no relationship to the guy or to his business, nor have I invested)
Ch”v I didn’t call anyone a scammer. The title of this thread is about due diligence and like you said it’s extremely high risk here. Money shouldn’t be raised from fellow yidden on LinkedIn, the only reason it is, is because he is not been able to get a single fund that specializes in this stuff to invest.
First of all I have started a business by bootstrapping it and I am in middle of starting another one now bez’h.
Tech-startup? Or a service business?
