The correct answer is that there is no set number.  They seem to try to interview as many applicants as they can in three days and then pick the ones that work from that batch.  Since PG believes that they are getting better at picking startups that will not die, my bet is that number will grow every year.<p>Another thought: I seriously doubt that the number of startups funded has anything to do with available capital, but rather the logistics of each startup being able to work directly with Paul.
