The funder/loaner/investor also takes a lot of risk... there is zero return if the venture fails...
At the minimum, they would want what the bank offers but the higher risk means they expect a higher return. Risk-Reward Ratio.
Even in silicon valley, the expectations of returns are high coz the failure rate is also high... the successful ventures have to carry/cover the failures...
Greedy when others are fearful. Very fearful when others are greedy - to paraphrase Warren Buffett
