Dear fellows, could you share tip for efficient presentations or brochures ?

Dear Searchers, would you be kind enough to share some tips about the suggested content for efficient ppt slides/presentation and 1-pager-brochure ?

Dear Investors, would you share the same on your side? Putting yourselves in the shoes of people who don't know about the model, what should we highlight/not forget/forget in our introductions to potential investors ?

If both of you (searchers/investors) were willing to share some example documents, it would be very helpful.

Maybe this post could become a kind of database for such docs to be more efficient ?
