In most templates you find for executive summaries, business plans, and pitch decks, you’ll find these two sections: Need (sometimes called Pain or Opportunity) and Solution (sometimes called Product).
Classic mistake: List benefits in the Solution section that are not obviously and explicitly called for by the Need section. Why? Because if you haven’t shown us there is a Need for a benefit in your Solution, why are you building it? Good entrepreneurs live and breathe the venture, so they don’t even realize that they forgot to list the relevant pain OR they feel it is so blindingly obvious that ANYONE will see the connection.
Don’t be that guy. Assume nothing. Walk us through it. Make your Need and Solution sections be a matched set, with every Benefit matched to a pain point.
