What do you mean by "product" over here? I guess you mean output? If you mean if there is any project out there with a great output, then there are actually a lot of good ones. You just need to find them out by yourself.
Never heard of Yanu. Kind of a sounds like you are just indirectly advertising for them.
I think it's all about the project for that coin on where it shall be used. Like those exchanges coins, the exchange itself is there product and their own coin is their currency. I think it's like that when we say about product.
