I like the graphical element above word Discovery in entry #12 and #13 because it conveys a sense of movement, like the business is "on the move". I wonder if perhaps the line could be made a little larger or thicker or convey even more motion? Or perhaps could insert spaces in the line and gradually grow width of blocks in the line as you move from left to right?
However, while the line and symbol is neat looking, I have to give a higher ranking to other design entries which incorporate symbols that are relevant t,o and emphasize, the business name. Examples are a magnifying glass and signs posts
