What are the key concepts in managing finances for a startup?

At the heart of it, the two concepts every CEO of a startup needs to know is this:

1. Revenue: How will you make money
2. Expenses: How will you spend money (in an effort to generate the above revenue). 

This is a very simplistic way of thinking about finances, but it is important to always keep in mind. For more information, have a look at the video below.
