There is a company I believe that does not provide a service that I would like to do. It would possibly require me getting a data feed from them. I do not believe they would understand what I want to do without me telling them. I'm worried they will tell me no and take my idea and do it themselves.
When you do the interview you can show a mind map to show what you can do for them, printed out step by step, laminated. Just how you can achieve their business goals.
If they ask to keep this print out, you tell them no this is "propriety" to my business. (PROPRIETARY 1: one that possesses, owns, or holds exclusive right to something; specifically) Or they will have someone else implement your plan.
No one cares for ideas. Don't worry about it. People care about products. Ideas are dime a dozen.
What type of data feed are you looking for and what are you trying to do? Send me a PM and I can provide more suggestions on how to approach whoever.
