Sorry, there is no such thing as "I will code and someone else will sell" when it is just you or even a couple of you. You have to sell/market as well. You know your product and market the best. At least you have to believe that.
There is no magic wand. You know who you are building this product for (hopefully). Find 10-15 of those people manually. Reach out using email/linkedin etc. Tell them what you are working on and if they will be interest in testing it.
Start creating content around the product. A blog post no matter how crappy you think it is.
Do all of that yourself first and may be you will attract a co-founder who knows this better than you but unless you are well connected or with a previous track record, no one will join you for sweat equity. You are in this all by yourself, at least in the early days.
