If it's a web and mobile product, you're going to try to acquire and activate customers, and you're going to build a high fidelity, minimum viable product, which is a fancy word for your website or mobile app will look like it's almost done, maybe the help files aren't there, et cetera, and maybe not all the features but the core features that people will use, and then you get out of the building, physically or virtually, and you try to get out and sell and see if you get users or payers or both.
