Pros
People are wonderful, everyone is friendly and there are (generally) no egos involved. People are curious about you, your work, and how they can help you. Rapid growth and extremely high potential. We are solving real problems for our customers and changing how they do their business, which is very motivating!
Cons
Lost aspect of "lean" that I looked for when joining a high-growth, startuppy place. All execs talk about moving fast, but I don't feel like this is possible when I'm not empowered to make decisions or (even worse) have my decisions overruled. The entire executive team (10 people) votes on everything and pretty much has to be aligned for big decisions (that or the CEO/ President can overrule). It seems like we're always planning for every corner case and outcome rather than getting a good-enough solution in place, and iterating.
