Lagged Deals and the Dynamic Nature of Venture Capital Databases

Venture capital databases are not perfect. One of the key problems is their dynamic nature. New information is coming in all of the time. Early-stage activity in particular is systematically lagged until additional rounds are raised (either because the earlier rounds were unpriced or because they were unannounced). For this reason, I try not to report data too recently from when the deals are to have occurred.
