I think you're getting at the crux of it here. The question is, how does one of these businesses "prove" to investors that they are less likely to fail? The failure rate for new business starts is famously high, whether that business is a tech startup chasing unicorn status or the corner deli. I think this will manifest itself in the due diligence phase, bringing back a bunch of things that tech founders have eschewed: detailed business plans, fundraising towards specific initiatives (as you point out in your post), and harsh measurement of progress towards those goals in board meetings with rapid consequences if goals are missed.
