Question about co-founders. Say one guy came up a good idea and has worked on it for some time. He wants to find a co-founder as you suggested. But how should the two co-founders split up the pie? Is each having 50% reasonable? If not, will the new co-founder accept a less share? How do you value the past work of the 1st co-founder and the new value that the 2nd guy brings in? It seems stupid to argue this when nothing has achieved, but this delicate and sensitive issue has impeded many cooperations. Your insight is very much appreciated.
