I share with anyone competing in a hackathon concrete, hand's on tips, for delivering a winning pitch. Consider what story you want to convey to the judges as you demo the value, and technical achievement, of your hackathon creation.
I first presented this to an audience at the HackDFW 2015 event. All pictures you see were taken by me as I advised and supported the teams as a volunteer.
Good luck to you! Reach out to me on Twitter @KenTabor.
