Many entrepreneurs who heavily invest in their business think they have found product/market fit when they really haven’t. It can be a disastrous issue when they begin hiring staff and optimizing their product before they figured out who actually needs what they made. You only really reach fitting your product to the target market when you are so overwhelmed with usage that you aren’t allowed, by your customers, to make any changes to your product because you are swamped just keeping it up and running. You can’t point to the success you have in building up a staff or pointing to outside sources of faith and funding. Entrepreneurs are often focused on the quality of their solutions and never listen closely enough at the problems that cry out to them. Actually, the problems out there in the marketplace are what outline the product. A shiny new product that doesn’t have a problem behind it will never find a product/market fit.
