Reference the survey from the stage three times during the event.

The Kastner protocol at ELX Congress is built around explicit on-stage references. At the opening, Kastner names the survey directly and walks through last year's changes credited to it. She mentions it again partway through the program. Her master of ceremonies references it a third time. The promotion is not a single cold ask at the end. It is woven across the whole arc so the survey lands in the inbox as something already in mind. The reframe is from "please complete this for us" to "this is how the room you are sitting in got built."
For organizers running flagship events where survey response feeds annual planning. The discipline is replicable at any size; the only requirement is committing the stage minutes.
