I think those are the baby entrepreneure assumptions, but something that is incredibly fundamental is to have the right distribution channel above all.
I was in Prospect Park recently on a Saturday morning and saw some stands collecting people's clothes and stuff for recycling and thought of Yoink. There are probably lots of groups like that to collect things. I would imagine they are using physical stores to sell things, or have some partnerships in place to distribute it. Have you spoken to any of them about how they give it away now, and the challenges they face in finding good homes?
