This document introduces Yesterdays Pizza, a company with a mission to deliver leftover pizza that would otherwise go to waste. It describes the problem that freshly made pizza is too hot to enjoy, and presents the company's solution of sourcing leftover pizza from restaurants and delivering it within 48 hours after it has cooled to an optimum temperature. The pizza is delivered using groundbreaking Pizza-to-Person technology, which involves ordering, sourcing fresh pizza that is then refrigerated for 24 hours, and having drivers slowly deliver it so it is at least a day old upon arrival.
