The frontline of any company is going to be their sales team, without sales the company is going to flounder and die, if you go back through the history of any large company there is a small company and before the small company existed there was a person with an idea and he had to sell it to someone else.
With that said and no matter where you are or which company you are with the art of developing new customers is the one constant throughout. It doesn’t matter if you are selling a product or yourself, you are going to need to find people /companies to sell it to.
