Interesting, but it only has valuations for exits. I'm kinda curious what valuations for going companies are, based on recent rounds of funding. The totals on YCList are nowhere near the $4.7B that PG quotes.
Actually, I'm surprised how many of the acquisitions were talent acquisitions for ~$2M/founder. Decent sized chunk of change, but you can get that much by going to work for Google, kicking ass, and then getting a FaceBook offer.
Most of this seems like it should be public information, since fundings that large are usually announced by press release. Has anyone compiled a list?
