Too cute for investors

Unfortunately, in 2013 most investors are still male. Coming in with a cute deck (curly flower background, pastel colours, retro-chique font, etc.) is not going to get you points. Even if your product itself has to be cute (a cosmetics line for teenage girls for example) you can still separate things in your investor deck. Use more macho graphics for the serious business stuff, leaving the cute graphics for the product show case pages.
