As I said on the post's own thread:
It's really 14 out of 80. You can't count the current batch, because they've just started talking to investors. Plus (a) several of the remaining 66 probably will raise series A rounds in the future, and (b) there are certainly more that could have but either got acquired (Reddit, Omnisio) or made it to profitability on angel money (Wufoo, Bountii).
