Am also a designer. v1? Just get the damn thing out. Don't worry about whether it has the perfect design or interactions at this point since the hardest part is simply launching (and you're going to change your idea/design once you get feedback anyways). After that, I believe a designer is invaluable, for taking user feedback and results and crafting the product into something that promotes more sales/views.
