What do you send prospects after a demo call? (i will not promote)

Founder-led sales question. After a good demo call, prospective customers usually has to sell it internally to people who weren't on the call. What I usually see is people sending decks or a recording of a meeting, and i suspect nobody looks at it. What do you leave behind that actually reviewed/shared? A short video? A one-pager? I'm working on this problem for B2B teams, so I'm biased, but I'd like to hear what's working before I make too many assumptions.
