The CEO had an awesome vision for the company initially, but no clear idea of how to continue to grow. Since we had no strategy laid out, we would work on projects for months and then switch to something completely different without ever launching anything. He was also obsessed with moving forward and would never take the time to fix problems, no matter how critical.
Ultimately he was unable to raise the series B funding he was looking for and was forced to downsize drastically, leaving no opportunity for career advancement.
He did put together a great team of experienced, enthusiastic and friendly people. Unfortunately they have almost all left now.
