I think the tl;dr is that you need to work hard in real life to advertise it. The person to person contact is important for expensive, low volume sales. One related item to keep in mind. Before you start selling lots of customers, potential customers will give you feedback a request/ suggest features. It’s important to try and separate those into “some one is suggesting a feature” and “you need this feature in order to sell your thing”. Don’t get stuck implementing every suggestion just to find that no one will pay for them no matter how many you have. You need to concentrate on the features that truest will sell the first 100 customers. I can’t tell you how to decide that. Only you with your domain knowledge can decide that.
