I didn't think the link provided a good analysis of an optimal number, but it was nice to have a list of some big names next to their number of founders.
It's hard to say how many founders works the best. You just need to find what works for your situation. I'd say it's usually on the low side so you're not burdened with too many conflicting inputs at one time. When you have founders upwards of 5 or 6, it reminds me of high school clubs/organizations where everyone was a co-President, co-VP, or co-Secretary. Sometimes people just want to ride along and get a position, whether it's warranted or not.
