These days I think of apps, then try and work backwards into a *startup that could grow out of it (and have the vision for x10 growth).
For example, an app for tracking expenses vs income => business owners tracking expenses => expenses in a business => selling tight integration into a POS (where the income happens) => startup about POS systems that integrate into your slick app (and yeah that exists)
