To aryrow a business you need a steady stream of customers and investors because cash-flow is the lifeblood of an enterprise. Yet lots of people around the world still feel uncomfortable with business development, marketing and pitching to investors.
In Silicon Valley there is a saying that the perfect combination of skills for a startup is a developer, a designer and a hustler. Often under appreciated, the hustler is responsible for ensuring that the business has a steady and increasing cashflow. The role of the hustler could be taken by someone with training in marketing, sales or finance. The art of the hustle is really just a combination of clear communication and hard work.
