The lesson
Open a switching pitch by naming the change before you show any product, and give that claim a whole slide.
The cover slide is near-black navy with the brand mark drawn as a faint glowing outline. Centered white text reads "It's time for a change," with a smaller line, "Switch to Linear to rejuvenate your product team." The deck then moves through the old way, a better way, customer quotes and a logo wall.
Don't open with a mood image if your buyer doesn't yet feel the old way is broken. Keep the one-claim-per-title discipline, and sell the change first.
