I think you sound like a friendly and mindful human being, but not as a business person should sound like.
I find your relationship to your investors money very strange. This whole thing is not a game. For me at least it is not about making a nice drawing app and building a community of people, who like to create pretty drawings. There is nothing wrong about that, but it is not the goal of a company. The goal of a company is to make money. Nothing more nothing less.
If i were to invest in somebody's company I would want that person to be focused on spending my money as reasonable as possible and give me back as much as possible or at least lose as less as possible by making as little stupid errors as possible. I would walk away instantly if he mentions giving my money to charity if he fails. I can do this myself if I would have wanted to.
Would you agree with me, when I say, that all these things are nice, but secondary for a business? I am with Adam Smith, who said, that these things follow naturally.
This was extremely classy Chris. Sorry it didn't work out. It was still a valuable contribution.
