I cannot confirm whether it’s the greatest or not (I haven’t checked them all,) but Andy Raskin on the Pocket has an excellent post titled The Greatest Sales Deck I’ve Ever Seen. In it, he details 5 elements to sequence any pitch and gives solid examples of each:
#1. Name a Big, Relevant Change in the World
#2. Show There’ll Be Winners and Losers
#3. Tease the Promised Land
#4. Introduce Features as “Magic Gifts” for Overcoming Obstacles to the Promised Land
#5. Present Evidence that You Can Make the Story Come True
Whether your preparing to pitch your next big sales opportunity or to raise your next funding round, you will find some insightful guidance in his post.
