Surely in your qualification and discovery conversations* you’ve covered the basic purpose of your planned meeting: who will be in the audience, what their expectations are, and an agreed upon agenda.
But when it comes to the meeting itself, have your host open the meeting and lay these details out for agreement. In this way, the meeting is by the customer, for the customer, and about the customer, rather than by, for, and about you and your products and services. If there’s disagreement or there are political struggles going on, the audience members can resolve these things themselves without you having to defend.
The stage is now set on their terms. Your presence is to help them in their decision-making processes.
Now you can begin to share why you’re there to show, how you’re going to do that, and what you want them to take away.**
