This is something any perceptive founder will pick up on very quickly (if they weren't aware of it, as I wasn't, before their first project). However, in my experience, learning to do it yourself is not an efficient or effective solution. You may have no other option at the beginning, but finding someone who actually does this sort of thing for a living is vastly easier (which is not to say it's simple). There are challenges to this as well, including how to afford them, how to pay them, and how to engage them, but that still costs less time than attempting to learn a trade that's based very heavily on things technical just don't usually do much, and the results are far better: If you think you'd make a fine salesperson, despite never having worked extensively in sales, you are almost certainly wrong.
