> VC returns are incredibly power law driven - i.e. they come from the 10-15 companies per year that end up being monsters.
You're almost right. Early stage investing is very much power law driven, later stage (more VC than incubator territory) comes in several flavors, some more relying on outliers than others.
Plenty of VCs won't even look at companies that are not yet capable of generating substantial revenues and profits, they are there as growth accelerators or to diversify founder (and early stage investor) risk.
There are as many risk profiles as there are VCs, you can't just lump them all on one pile.
