Hi :)
So my idea has evolved. I've made it more dimensional. The echo only shoots upward, instead of both directions. The echo is transformed into an arrow-like shape as it gets towards the top...As to symbolize leadership, direction and literally building up. The base of the building are your business acronyms "E" and "B". They are somewhat abstract, but are still recognizable as letters and blend into the design seamlessly. I chose a wider and heavier font because I thought it would compliment your industry more.
