It is certainly possible, but you really don't know. Especially given that the numbers are so small, any false negatives would affect the data quite a bit.

A better source would be a survey sent to YC companies, or perhaps data from some internal YC database. That will have its own sampling issues, but the accuracy will be leaps and bounds above Crunchbase.
