I would be very interested to hear from anyone who has founded a startup about whether there are occassions in which you would want any more than one other co-founder and whether there is a limit on how many you think are appropriate? I'm not particularly savvy on startup culture but could reasonably justify up to 2-3 other co-founders depending on skillset. I would greatly appreciate any thoughts based on experience!
In my experience (which isn't a ton), I really enjoyed having 3 person co-founding team. As far as decision making it helps to have that number of people to help settle debates. Strictly on that level it was a positive as long as there is a level of cooperation and dedication with everyone.
It varies a lot. From what I've seen, two is most common and more than 5-6 is a bit odd. More than about 8-10 is hard for sociological reasons.<p>How well the team integrates and works together and whether or not you have adequate skill coverage is more important than the exact number.
