From Aron Susman of TheSquareFoot:
I joined my first startup about 4 years ago, early in the life of that company. We had about 50 paying enterprise customers using the product and who willing and eager to share feedback to make the product better. While I was there, we were lucky enough to grow and continued to add customers to our subscription service. We grew enough to get our cash burn down to zero and eventually became profitable (20mph – 100mph). However, we faced many challenges along way. Some of which at the time made it seem like we were never going to make it through.
Essentially, we were facing a scaling problem, except I did not know the term because I did not go to business school and it was my first startup experience. In my naïve mind, all startups were equal in the sense that we were young companies trying to grow. As we grew and overcame the challenges of scaling a product that our customers needed and loved, I put those lessons learned away for the next start-up–preferably one I founded myself. I honestly thought the hardest challenge of my professional life was behind me.
