Ask HN: How do you find a good foundational VC?

It seems like for every Don Valentine out there, there seems to be 9,999 bad VC's out there that are more than willing to inflict horrors beyond your nightmares and blow up your idea into nothingness while throwing you into the abyss. While they do have a purpose as the latecomer 300th investor, they are very dangerous to have as one of your first set of investors.

Getting someone like Don Valentine to invest in you is going to be very hard since he probably is invested in somewhere else in addition to getting his cell phone number. That leaves you figuring out which 1 of the 10,000 new VC's out there is a good one.

How do you figure this out? Especially if that good investor has yet to make a name for themselves.
