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.
