It doesn't work that way unfortunately. The founder(s) have to sell initially because you know your product the best. No external sales person can come and suddenly get all these sales. You may hate sales but if you want to start a business, you are the best salesperson for your product/service.

There is no magic wand to this. You just learn sales by doing. I am a nerd myself but when I started my company, I automatically started selling which is mostly just trying to talk to potential customers and understanding if your product can solve their problems. Only you know that best in early days.
