Pros
From Day 1, Propeller leadership has shown extreme transparency both in operations and strategic positioning of the firm. Not a day goes by when I don't learn something new about the industry or a client industry from fellow consultants as well as members of the leadership team. The firm is very accommodating of employee led initiatives both inside and outside of the firm. Because most of the leadership has been with the firm since inception, they are not only aware of but responsive to consultant concerns while working with clients and work to positively mediate any issues while maintaining good relationships. There is a true sense of fiduciary responsibility to both consultants and clients which takes alot of time and effort to maintain but is also top of mind.
Cons
No downsides about the firm so far, just be sure you understand the consulting industry in general before you enter. If you believe it's right for you, you won't find a firm better than Propeller to work for or engage with as a client.
