You can't really have growth without a product, but like PG said in the top comment, that's not a reason not to apply to YC. You can probably still assess demand - hopefully because you yourself want what you are building. That's also helpful for us to say, though again not make or break.

The most important things are the founders and their relationships to one another. We want great founders with great ideas and the tenacity and ability to go after them.
