As a business consultant you need a leadership logo design that would personify your expertise as well as a personal brand identity.
You can select industry specific leadership logos of books or graduation cap symbols for education consultants, or a human head with brain symbols for psychiatrists.
Alternatively, you can select a personal branding style such as an abstract person with raised arms in front of many holding a star or at the top of the ladder. Symbols of mountain peaks with a hiker holding a flag also tend to be popular.
Modern leadership logos also feature just torch icons or simple wordmark of the leader’s name.
Ultimately, it’s up to you to determine which leadership logo image suits your business consultancy.
