(1) This logo needs to simple, clean and professional since the audience will be executives for companies. it needs to look professional.
(2) The service offered may be combined with some other service so the logo should be flexible enough that some other firm can add their name to the bottom of it and it still flows.
Here is what I mean:
here is a firm https://www.hightoweradvisors.com/home (see the logo)
and here is firm that operates under them...  http://pinnacleequitysolutions.com/consulting/find-a-cbec/eastern-united-states/baltimore-md/hightower-logo/ (I found the logo here) 

Using colors is ok.
