Pros
Great work, great environment, an increasingly clear vision toward a noble aim with lots of opportunity.
Cons
There is a bit of chaos as things grow fast, but it's pretty clear up front that's what folks are signing up for. The thing that prompted me to write this review is in response to some of the negative comments. Either these are isolated cases or falsified, as the behaviours that emerge from the company's values would not sustain this on any scale. Yes, there are some inexperienced managers, but the culture of openness and autonomy that exists pervasively makes me wonder how these issues could not have been raised and dealt with, as so many other things are on a daily basis. So that's my "con", that for whatever reason it seems there are people in the org who were carefully hired based on a set of values, but were unable (or unwilling?) to work things out in the most positive environment they're likely to come across. Other than that, software is hard, and that's true here too. The ways that it is hard varies by product/project.
