Doesn't capital also come with the expectation/pressure you need some sort of liquidity event in the next X years because the VC's fund depends on it?
In practice seed investments consist of multiple $100k-$250k checks, which are generally too small for the investors to put any pressure on your startup. Seed investors write dozens or hundreds of these checks, and they don't have the bandwidth (nor desire) to put any pressure on the founders. The pressure kicks in when you raise series A and get partners on your board who only make a few investments per year.
Definitely interesting if there are other good routes for "slightly-too-big-to-bootstrap" ideas (beyond the obvious "savings" and "transition from consulting")
Where does your belief that they do come from?
I wonder whether they've paid dividends to YC?
