It looks like 21/102 so far have died without raising more money. The rest either raised money, were acquired, made it to profitability without raising more, or are currently live and either raising money or planning to soon (e.g. few of the startups from this summer have actually closed rounds yet). Ultimately the failure rate will be higher than 21%, obviously, but it will be several years yet before we know what it will be, because it takes 3-5 years to be sure how a startup is going to do, and the median YC-funded startup is 15 months old. BTW, 2 of the 102 (Parakey and Justin.TV) were ordinary asynchronous investments and did not participate in any YC cycle.
