Usually, a pitch starts really great. When asked, out comes a short and to-the-point story about what you are about. Then we add more info on this, more info on that, until we have diluted our story so much that it sounds pretty much like any other company or fund in your market.

Use the fact that everyone in your industry is creating noise about why the market is so bit, how it is growing so fast. Trigger a recall of this information in the mind of your audience through simple charts. Focus the majority of the time and slides on that unusual story about why you are different than all the others.

Maybe it is good to record that very first pitch on video so you can go back to it in the middle of the design process. Part of the value of a professional presentation designer is sticking to the story that came across in the briefing.
