Selling, negotiating software
Selling software is not an easy task for start-ups today. The market is big, solutions abound, and there are very large and distinguished corporations in the market.
Okay, let's start with what does not work: have you ever heard someone offer "integral solutions", "applications in any language", "software maintenance", "project development"? No matter how sophisticated and efficient it sounds, it does not say anything specific; besides, let's be honest, even though you can dedicate yourself to everything, it is not optimal for a start-up because intellectual resources can abound, but humans can not, and if you want to maintain a good standard of quality, you have to specialize.
