Pros
They pay very well/great benefits and attract some really great people with the mission. The camaraderie you develop with coworkers is akin to being in the trenches at war - you band together and get close to get through it.
Cons
The strategy is constantly shifting. You will put in months of work in one direction, only to have it suddenly changed - usually after a board meeting or input from a few key board members. Management does not stand up to the board to stay on track with previously set goals and initiatives, but instead sways with the wind. People who stay here are okay with that and can tolerate the constant churn - or they like the money they are being paid.
Oh, and efforts to be inclusive will invariably result in disaster of some sort, so expect ongoing talk about that.
The financial setup of the company is terrible and results in most of these problems - relying on one person for funding is never a good thing, and efforts to get a better income stream flowing have apparently failed.
