The three questions
Who does this replace on my shelf?
A buyer has fixed linear feet. Every new listing displaces something. Answer the displacement question before it is asked.
What is the velocity assumption?
Units per store per week, with the reasoning behind the number. A range is fine. Silence is not.
Who pays for the first six weeks?
Trade support, demo schedule, and the point at which the brand stops subsidising.
What this means for the deck
Cut the origin story to one line. The rest of the meeting belongs to shelf math.
