That $45.2m figure was not the average valuation of all cos we've funded, but the average valuation of companies with known valuations (either by raising an equity round, being acquired, or dying, in which case the value is 0).

I realize that unless something is changing, the more recent companies that don't have fixed valuations yet should have the same sort of distribution. But that quote in Wikipedia still makes me a little uncomfortable, because it's not strictly correct.
