Depends who your 'real customers' are. If you're launching a product where the type of customer is the type of person who would use product hunt, you might get customers. If not, you probably won't.

Promote your product where your target customers are. (Also consider the audience for promotion style. If your doing tech services cold emails or being contacted cold on linkedin is a great way to get on a product blacklist. Never annoy the people who control the spam filters.)
