Yes. The unconscious assumption -- evidently made by female as well as male VCs! -- seems to be that a female entrepreneur is much less likely to found a company that will become huge. If an opportunity has less upside than others, it is natural to look more closely at the downside risk.

I wonder whether YC has managed to free themselves to some extent from the effects of this bias by standardizing their interview process.

I would be interested to know if there were any variance in marketing materials/information provided by male vs female led firms that might seed the discrepancy.
