Yeah, it is difficult to start any marketplace. A chicken or the egg problem. I was hoping that by releasing early I could get some sellers on board. It's considerably harder to get a designer to create a work to sell on a marketplace that isn't even launched yet or validated by buyers. However, I've made a couple sales (literally, 2) and hopefully I will get more, enough to attract the sellers.
I have emailed a few handpicked designers already so I will see what the response is. :)
