Laex makes a valid point.

I would suggest you stop and take a day off before you get fully burnt out.

There is no sense in spending all this time and energy on a product you haven't even validated especially before you've launched.

You could spend years making the "perfect product" without ever knowing if the product is something someone will purchase. Or you could ship a minimum viable product and test whether your product is something someone will purchase.

Eric Ries talks about the minimum viable product in his book "The Lean Startup", which I would highly recommend. I think it would help you and your marketing partner get some much needed context to your situation.

Good luck!
