Hello!
I can do this for you, I did do few pitch for my clients, as example I will give you a positioning statement:
This was for a service in an airport.
"Our solution will reduce stress and provide peace of mind (Outcome) for the recreational passenger who has checked in late (Target user), by giving real time personalized feedback on exactly how much time there is left to get to the gate. (Gap closed)"
Of course this is just a piece of the whole pitch.
So, I hope you like this and want to work with me.
Best regards
