Seems to me to be a high labor effort with fees similar to Ebay and a much smaller audience.
They claim great results but are capacity limited which will not continue to be the case.
It is not clear to me that there is a shortage of marketplaces and venues. And some venues like Amazon already have too many sellers for the number of buyers.
Seems like a place one might try if it appeals to the way you want to do business, but whether it has a future is debatable. No reason to buy it - would be cheap to replicate.
