Sia is another blockchain based storage platform I think could be good to talk to. I don't think they are as well known as storj, but the devs seem to be making progress and have some interesting ideas/applications. Currently you can lease/rent storage as long as you have a few Siacoins. I think working with either storj, sia or both could be big, as most people won't want to pay for storage in some arbitrary currency, but instead with something they are familiar with(USD, EUR, etc).
