I really like your designs - they are all just fabulous! I don't know how you could strength these. As such, yours are in the top-tier and very capable of winning this contest. I'm still sitting with all the designs before i rank the new entries, but I'm very pleased with what I see. I mean they are very simple, yet sophisticated and distinctive. The use of color is soft yet pops with warmth, and the light bulb is genius.
You're the front runner right now with entry #28 - its a just a great design. I would like see if you are willing to re-size the light bulb element a bit. I'm interested in what the logo feels like and whether I lose detail with the Light Bulb no taller than the top of V in venture and the base no lower than the start of the S in smart growth - hope that makes sense.
Here I work in different changes on the size of the light bulb, In some cases I striclty make the size of the light, not longer than the letters, but in other cases I make them pop up a bit, generally in graphic design the image (ISO) part of the logo should be more important or bigger than the text (Logo Part) so it gets a better "optical" result to the eye, I think that the old entry was way bigger than it should be, so here are some versions, some of them have slightly touches in the color, and some with different typography.
Let me know if you want to see something else, absolutely no problem...
