+1 If the idea is so simple to execute that you're scared someone will steal it and screw you it's not a good idea. You can try to be secretive and they will just steal it after you release your beta. That's why I never deal with "stealth companies", because the whole premise is "we have an idea, and we don't want to share because everyone will do it". If it's that simple to copy your idea your business will crash. Now, if by "trust" you mean someone who will provide you with honest and valuable feedback it's different.
