Read an article today in a popular biz mag about how a founder got into an accelerator more than once. The second time, by calling up the head of the program directly and pitching whatever ideas he had to see which would stick and got into next round.
Why do high profile accelerators allow past graduates to re-enter the program with a new idea when they already have access to the network? That just takes the spot of a team that really needs the guidance, network, exposure & backing. I actually thought the selection process was mostly unbiased. Silly me.
