I desparately need help on figuring out which type of presentations go for the following four audiences:

Board of directors of the parent company
Small groups of venture capitalists
Commerical and Investment bankers
Stockholders @ the stockholders meeting.
If I can get help with what type of presentation each audience gets(motivational, informational, etc) then I can go from there.

First, think about what you're trying to tell these different groups. For example, you may want to inform the board of directors about the accomplishments of your company or division.

This site may help you decide which type of presentation will best fit the audiences.
