Perhaps a more simple and direct way to show the development with an arrow as well as with the negative space and positive that can evolve together to form a letter "e" in 3D
Entry #9 is starting to really communicate the idea. Look at the other entry which uses the numbers. Since we mainly do work for financial companies and accountants, their idea is also interesting.
Thanks for your entries. As I come up with additional ideas/direction, I will contact you.
FYI, I lived in Firenze from 1984-1985 and I miss it very much.
Using #21, would you just make the top line of the "E" slant up a little? Just this one line to to indicate a growing business.At this point it is very close between your logo and the one in 1st place. Thanks for you work; it is much appreciated.
