I've heard about small groups that meet to help keep founders on track. I ask because I'm jealous of my friends who have found cofounders. It definitely seems to be a big help to have someone to regularly talk to about challenges, goals, and to keep each other on track.
When I was in the Founder Institute, we had weekly meetings with a group of 4-6 people. It was helpful but I came away thinking that an even smaller group, like 2-3 people total, might be of the most benefit.
Have any of you have experience with groups like this? How was it organized? Would any of you be interested in such a group in SF?
