Co-founders or not, the underlining reasons are alike for people (entities) with different personalities (characteristics) working together.
Only one person in charge will always do, if he or she has a very strong personality and also has appropriate supporting subordinates.
Two person founding team will be great if their personalities are complementary, thus one plus one is bigger than two. There are many very successful enterprises in this group, such as Apple, HP, etc.
In initial phases of founding companies, projects, etc., always avoid groups of three strong personalities at all costs. Trinity is a very special case that will ensure endless internal fighting/competition, low efficiency and sustained tensions. However, trinity is good for long lasting (market) competition and ensuring all parties will not be easily wiped out. Example cases: a) US-Russia-China relations; b) President-Congress-Senate structure. c) Firefox-Chrome-Edge browsers;
For groups bigger than three, if the number of prominent members with strong personalities is less than four, see previous cases. Otherwise, avoid at all costs.
