Pros
There is room to be creative if you want to put that into it. There is limited oversight, if you are on the right team and are decent at project management.
Cons
It's a typical mid-life cycle startup agency. They had excellent organic growth, and the employees benefited from it with bonuses, yearly promotions, and extended holiday. But the partners have been pushing for more sales despite the administration change and a recession. Benefits are being slowly cut, and rationale is that the company is growing. Most of leadership are scientist who transitioned out of academia after grad school. Most don't have formal management training, and they can be sensitive to negative feedback. They aren't terrible managers, but it's kind of like a 10 year old babysitting a 7 year old. If you're established here, it is a fine place to work. If you are looking for new opportunities, I wouldn't recommend getting on board right now.
