This document provides tips for nailing sales demos based on Gong.io's experience improving their own demo process. It recommends starting by understanding buyer personas through interviews and feedback analysis. Then create a demo playbook by reviewing your own demo recordings to identify best practices. Provide continual coaching to reps by having them review highlight reels of top demos and recording their own demos at milestones to assess progress. The goal is to give reps a repeatable sales process and help customers have an "ah-ha" moment through an optimized presentation.
