The failure rate is probably skewed low by YCs growth rate. For example, 1/9 of the companies were in their most recent batch, and it's unlikely that any of them have gone out of business yet.

Still impressive though. Any success rate over say 10-20% seems really impressive for an incubator.

The breakout-success rate thus far is also skewed low by YC's growth curve. Things have still just begun.

Yeah. A failure rate by cohort (a "churn rate" of sorts) would be handy.
