You don’t have a deck problem. You have a perspective problem.
In short, you’ve built a product-centric deck. Focused on capabilities, differentiation, and proof. Forgetting that buyers don’t adopt a new way of thinking because you showed them more evidence — they adopt it because you showed them a different way of seeing their own problem.
And so the deck does its job. It explains. But it doesn’t convert. The room nods, asks for a vendor comparison, and tells you they’ll “think about it.”
