Where I work is pretty fun, however, I feel like as a company/startup grows it becomes harder and harder to keep it fun. Not in the sense it that it is no longer fun at all, but keeping the same "culture" fit with new team members is hard. Your companies "culture" is something that grows organically with early employees, but as you hire more people, eventually much of your company "culture" moves towards ritual, which while is intended to improve the culture it is less genuine.
