Pros
Founders who lead with character and by example - a rare thing given the predominantly corrupt and self-serving ways of today's world. As a result, their goodness rubs on you! The entire organisation is made up of mostly sincere, generous, helpful, and humble people. You get to work with some of the smartest, most dedicated, and competent professionals in the field. The culture is one that allows for mistakes and experimentation - a great thing if you're one to be creative and innovative. They are open to change; they listen to new points of views, implement those that are sensible, and continuously educate themselves on the newest processes and practices that may benefit the organisation. You get the professional support you need - all you have to do is ask. There's budget for upskilling, trainings, conferences, and the management is always on the lookout for the right people to train and grow the teams. They care for your mental well-being. They have an HR who listens and offers friendship - they even go out of their way to help the expats get acquainted with their new environment and settle in smoothly in their new country.
Cons
More seasoned business people may need to step in so that the great culture result in profit. A democratic style of decision making might be better replaced by a system wherein the lead (whom we assume if the most learned/experienced in their field) has the final say.
