"He [pg] said that this time around, YC looked at 'predictors of failure,' not just 'predictors of success.' For example, he said that in the past YC might have chosen a company that had great founders (a predictor of success), but this time it might have filtered that same company out because those founders, while great individually, all hate each other (a predictor of failure)."<p>The given example implies that YC has chosen founders who don't like each other in the past. Seems remarkably odd and hard to believe IMO. It may have meant to say that the founders seemed LIKELY TO hate each other eventually but if they even disliked each other at the interview, I can't imagine the YC partners being ok with this.
