I've found Linkedin to work reasonably effectively for marketing / sales personas.

In general I'd focus on the problem and not the solution you're proposing. In your initial out reach message and during the conversation.

You should also try to get the feedback that might invalidate your idea. This will get you thinking about why your idea may not work. Or how you may need to tweak it or test it to avoid this scenario. Better to learn this early than later! Don't be afraid of getting shot down :)
