The PPM (private placement memorandum) is a big book that investment bankers prepare when they want to sell a company. It contains all the facts about the company, the legal fine print, disclaimers, and warnings about risks.
Often, this PPM gets used without modification as the sales presentation (investor presentation) of the company. Unfortunately, your presentation design efforts starts with the PPM, rather than ends with it.
Why is a PPM a poor sales document? It contains too many pages, it has a logical rather than a story structure, it is not targeted at a specific type of investor, it is not very visual.
What to do? Finish the PPM, put it aside, and start designing a sales/investor presentation from start, for a specific type of investor. Tell why she should buy your company, and eliminate all facts and detail that are not essential for the first meeting.
The full PPM is the fact base that is needed for the 2nd, 3rd and subsequent meetings, not the first one.
