Nobody cares about a solution if they don't understand the problem it is solving. I'll help you build a deck centred around the problem you are solving, getting investors personally attached to the problem and making them want to support your solution. 

Many founders lose investors' attention when rambling about specific features. Investors are backing your business; they care about the idea and the vision, not the detailed product features. 

This doesn't mean you should just tell stories about yourself. It means that what goes into the deck and how you order it should all be decided by the story the deck as a whole tells. Your pitch is like a show; it needs to have an overarching narrative. 

A pitch isn't a movie. It's social interaction. You need to be aware of how investors are reacting and adjust accordingly. If you don't understand the social dynamics of the room, you are leaving to chance the most important aspect of your pitch. 

Each company has a black swan, an idea that if investors believe, they will be 100x more likely to invest. For Airbnb it's that people would stay in a stranger's house. If investors didn't believe that, they would never invest. You must find your black swan and discretely hammer home that idea during your pitch.
