When you try to do something completely new, the only way you will know whether customers like it or reject it is if you show it to them.
This is precisely the argument for why you should be running experiments again and again, as you try to move forward from idea to a product or a service; you need to take stock of your customers to see, if you are essentially on the same page as they are. It not, redo, retool, relaunch or just stop.
Show your ugliness. Give your idea a spin. A little time and money invested in the right experiments go a long way into guiding the big product decisions that are truly costly.
