The "series A crunch" suggests that VCs don't have enough money to invest in all the startups that they want to. But almost all VCs have much more money than they know what to do with. They raise huge funds to rake in millions per year through management fees.
The problem is that traditional VCs can't manage very many investments. So only a handful of series A VC deals can happen per year.
But there is a nearly infinite supply of money just waiting for another way to invest in startups that isn't VC. Things like Kickstarter from the bottom up and AngelList from the top down are the harbingers of doom for most VCs.
