Pros
Acumen does pay on par with relative competitors, but do not count on those promised bonuses - any reason not to, they won't pay out. A lot of good and smart people in the company, but none of them have power. Those with power are quite the opposite, not good, not smart! - but more about that in the cons section!
Cons
Not sure where to begin. But Acumen has staff turnover like no other place I have ever been - apparently a lot of people had a lot a reason to leave. - Broken / forgotten promises from management - Bad client relationship management - Product focused, not people focused (As a consultancy, your people are all that you are!) - Corny and patronising internal communication - Spending 25-50% of your time satisfying day-to-day Acumen tasks vs Client work - Complete lack of trust from management, to remote teams and individuals - Constant management embargos on team and client messaging - Unknown in the market, and no desire to push for better market recognition - Huge dependency on a few clients, and even fewer products - Politics from above are incredibly childish - Generally untrustworthy!
