Hypothetically, if friend A has an idea for an app, and friend B can turn A's idea into an app. And, both A and B decide to create their own app developing company and pursue the idea. A has 100% idea and B has 100% skill. Then, who's more valuable to their company? Who should have the higher percentage of ownership if both spend the same amount of time and money for the app development? 50/50 is not an option.
