How to Be a Successful Early Stage Company

How early do you usually work with the companies? Are these companies that are already huge and they have thousands of potential customers? Or are these also startups that are just trying to get their product market fit. For our client work, we usually work with companies that have a minimum of 300 conversions a month. So it's usually more high growth companies. However, we do have courses. And when we do the courses and the trainings, they are for more of the entrepreneurs and startups that want to learn how to do these things themselves.
