In my opinion the most interesting number when it comes venture investing, is what the hedge funds are putting in now:
"While venture capitalists poured $11.3 billion into startups in the first quarter, up only 11% from a year ago, non-traditional funds invested $6.4 billion, a 167% increase, according to a report on Tuesday from CB Insights, which tracks the market. Two years ago, the outsiders contributed less than $1 billion."
