Is there such thing as a job where you just listen to a person talk about a thing they are creating, and you ask questions and get them to detail it all, and poke holes, and get excited with them, and help get them over a creative slump, or think of angles they might not have?

I'm sure different industries have versions of this role, whether writing or starting up businesses. I'm just curious what the job titles are.

Or, is it just always someone w/this personality in some other existing role, that brings this value by being free to express this way?
