It is inevitable that, during your career as an entrepreneur, you will have to deal with investors. This is the reality of the startup ecosystem. Without the aid that these individuals can provide, many companies would never even get off the ground, let alone become successful.
No matter what field you work in, there is one fundamental need that is transversal to every startup: proper funding. Without investment, your company will not be able to operate, leading to an untimely shutdown. To avoid such a fate, you need to attract investors and sell them on your project.
