A compelling pitch deck?

I was asked to answer the question “What makes a compelling pitch deck?” on Quora, and here is what I replied:

You can write books about this, so without giving a table of contents (Google it) here are some thoughts:

• Something that explains what you actually do (yes, some decks don't)
• Something that intrigues a potential investor enough to have another meeting with you
• Something that answers the big obvious elephant in the room questions ("What, that sounds like a page rank search engine")
• Something that shows through language/visuals/style/in-between-the-lines that you are a decent, honest, professional person to work with
