I do like the overall direction of #27 and #27, but the grey makes it difficult to read "Business Intelligence". #26 and #25 I think the fond is a little too heavy, not refined enough. The font choice in 27 & 28 is much better for this project. Also I haven't been too fond of the initials BBI, except in one or two cases where they have been rendered a little more subtly. I hope that helps.
