Say one has enough income or assets to be an accredited investor, but doesn't want to spend the time to figure out what private market investments are worthwhile. Do there exist any low fee broad market index funds for that?
EquityZen has an index fund of sorts, but the fees are high and it only includes companies that are on EquityZen which are probably not representative of the average.
I'm not sure how much you need to join a round with a VC fund (and they would distribute that into a bunch of companies for you), but that might be your second best bet.
