Pros
Overall, the people are creative, open to collaboration, and work very hard.
Cons
The company leadership changes direction so often that it is hard to know what your goals and your role are from month-to-month. Unrealistic demands regarding product development, sales, etc. are placed in front of teams, often without the team managers weighing in. One of the co-founders has much grander ideas than are realistic given the resources of the company. They have experienced lay-offs within the last year on certain teams, with high turnover in some key roles (CEO, VPs, etc.) There is also no HR director, which makes it difficult to bring concerns forward as an employee without fear of reprisal. There is also no clear product and future revenue stream other than capital investments.
