I am an entropaneur and have been a CEO of many companies in different sectors - I want a ver clean logo that can be very vague since the specialty is so diverse - I would use my engineering background to promote green clean energy as well as financail, security, and other subjects. The personality should be wealth of knowledge and cutting edge.
Markets are Healthcare, Energy, Security, Logistics for larger companies, Defense sector - Audience can be Healthcare Providers, Companies that want to take their companies IPO - Care about energy. This is an International Company so it will be working in the Middle East, Europe, South and North America - Audience could also be Governments.
Color is important as well as a CLEAN logo - Silver should be there perhaps with a bright color or just black perhaps - Carlyle Group, Blackstone Group, etc - Clean approach. Not too busy.
