I'm a software developer and some time ago, I've shared an idea to a friend. I've said, look, I think that this app will boost your services and someday I'll do it for you. That friend was very excited about the idea, but we postponed the implementation because of my schedule.
ATM, this friend wish me to give him my idea, in order to hire some developers. Because of that, I feel somehow betrayed. I'll be happy if my idea will boost his business visibility, but I'll like to get some financial revenue from this idea too.
Which is the best way of doing this, without hurting his feelings?
If I had to build the app, the price is more easy to set, because is proportional with the worked hours.
In this case, I don't know how to approach the situation. Can you tell me your opinion?
