I would wager it makes far less of a difference than you imagine. The problem here is survivorship bias. We naturally hear far more about consumer startups because we are their target audience (in a general sense). Therefore, we hear about consumer startups that fail more often than about enterprise startups. It then seems that enterprise startups are less likely to fail.

If that were true, the fact that VC money is focuses far more on consumer startups would be ridiculous. Surely if enterprise startups succeed more often VC firms would make investments where they could benefit from this fact, likely by structuring deals around taking a percentage of profits since big exits are rare but long spans of profitability would not be. There would be no point in playing the consumer startup lottery as you would be greatly overpaying for risk.
