Kevin Stambaugh, Shelfbucks EVP, Chief Product & Data Officer: "Most companies playing in that space are trying to do in-store mobile marketing. The single problem they are having is they can't justify the infrastructure cost. The beauty of what Shelfbucks is doing, we found a way to pay for the infrastructure and to get millions of beacons into stores. No one has figured that out. That's why it is so important for us to do this first, because then it makes everything else possible."
