I look at competitors, see what they're doing, find my own style, and the way that I like to do things. My style usually fills in the gaps because I know the context of the competitors, and usually, I'd be entering the market with some experience, so I could somehow fill the gaps. If that doesn't work, I would just blow up Claude with context and tell it your goal in that market and ask it to find gaps.
