Ask HN: Post-YC Startup Numbers

Just trying to make sense of some numbers... According to the Inc article, 27 out of YC's 145 funded startups have failed, 7 have been acquired, and 2 have merged with other YC startups, meaning that the majority of the startups--a full three-quarters--are still hard at work. PG recently posted that about 200 people are employed by YC-funded startups, which works out to be a little less than 2 per company on average (109/200). Plus, some of the companies employ a dozen or more people, which makes the distribution even worse. If you assume that the majority of the companies were founded by at least 2 people and that not many founders have started more than one company, the stats indicate that a lot of founders have moved on to other endeavors, no?
