All your non-defunct fundees are still "building", but that's not the same as accepting groups you know are going to take two years and a lot more funding right at the outset.
As for caring about the founders/investing in people instead of ideas, that doesn't hold up for several reasons: 1) If you really end up changing the idea so often anyway, as often claimed, the idea proposed wouldn't be grounds for rejection if the founders were otherwise good; 2) Many founders don't have track records, thus you have nothing to judge them on; 3) Some applicants do have track records, but you reject them without reviewing the stuff they've done due to lack of time or other reasons.
