When do I need to think about marketing?

Day 1 … before you buy a domain before you choose a name, think about how your name is going to appear and where in the world. Your name and domain will (hopefully) be everywhere you want it to be. Ensure that you minimally have a marketing sense of how the name ties into your brand—either it has some relevance to you the founder or the product. It’s easier to change a logo than a name — be comfortable with it and believe that it can lead your product to success.
