Demoing a product by starting with the home page (or, actually, starting anywhere on the website or in the app) is like a realtor showing you a house starting in the living room… Consider, instead, walking through the front door — having come from somewhere, paid attention to the neighborhood, the cars on the street, the front porch.
Start with the first moment a user might learn of your product — maybe it’s an email invite, or a text from a friend, or a notification of a forced install from their IT department, or they heard about the app from someone. Then show what that first-user experience looks like.
If you think about the demo this way, you’ll gradually open the eyes of your audience so that when you do arrive at the actual service, they’ll be more likely to have that ah! moment.
And this goes beyond just the demo: most of us think of the entire product as what’s really only the “interior” of the house — the features, look, and flow of your site or app. We might be better served thinking of the product as including the “exterior” of how users will encounter it in the course of their day…
