You have already validated your great idea and know that this app will conquer the market? Now you want to hire instantly an app developer and get the job done? Congrats! This way you will not only lose precious resources in terms of money, as the developer would have to start from scratch, but you will also regret that you haven`t set up a prototype to better understand your final product.
