Most product pitches go something like this:
- Existing solutions have this problem
- Existing solutions have this problem
- Existing solutions have this problem
- Existing solutions have this problem
- Existing solutions have this problem
- Our solution does not have this problem
- Our solution does not have this problem
- Our solution does not have this problem
- Our solution does not have this problem
- Our solution does not have this problem
The story gets repeated, which makes the whole things boring. A better option is to elaborate on the problems, but then keep the solution section relatively short. You can even show a grid of small screen shots of all your “problem” slides, with tick marks over each one of them.
