I'm a developer and in my younger years, I actually entertained a few "ideas guys". The problem? While you spend 8+ months working on their great new idea, "ideas guy" has all the time in the world to: 1) keep bother you and wondering why the project isn't done 2) move onto another "great" idea 3) if you do finish and that person has moved on, they will lay claim to your idea (even if it's not legal, it's not fun going to court). Plus, once your app is finished, what will the ideas guy do? Most people aren't cut out to run a business. You need to choose your partner well. So, I now only partner with another developer, someone who can bring money, or someone who can bring a user base once the app is actually launched (IE: they have an existing business in the same field).
