I like both of these. I like the #4 because it looks military and tech all at the same time. I also like the A and the F in the logo. Pretty cool. I like the font in #5 too but the circle logo/letter doesn't hit me as strongly.
#5 looks nice but maybe too close to a military look. I'm selling to enterprises (large companies) and I'm working with their databases to extract information. Cool logo look but maybe a little softer...Thanks!
#5 - growing on me. Still think it's a bit too much though. I do like the colors and the round logo. Thinking of how it could stand alone and still represent my company. Could you work on some variations of it for me to look at? Thanks!
