Pros
Having worked in two client facing roles over a period of a year and a half, I can say confidently that this is the best company I've worked for. Senior leaders and the CEO are always visible and encourage you to offer your perspective in practically all areas of the business, no matter your role. Culturally, Consumer Intelligence pioneers when it comes to staff structure and management, which aids innovation.
Being quite a small company with such an outlook consequently requires staff to step outside of their comfort zone often, which in my opinion is only a good thing, and one is always praised when they do so.
Crucially, the team are a great group of people. This almost trumps all that came before. At the end of the day, it's who you're working with that you'll draw the most inspiration from, and Consumer Intelligence offers plenty.
Cons
I'll preface this by saying I don't necessarily consider the following to be a con.
Conumer Intelligence is always striving for greatness, which can lead to the occasional crisis of identity. Similarly, it's important to move ahead at a rapid pace given the clientele, so a strain on resources every now and then is inevitable.
I doubt there would be many SME's in the UK where this doesn't occur.
