We like the circle graphic of #12 and the layout of #11. Most of your designs are 2 color (which we like), can we try #12 with 2 colors? We also like the feel of #19 and would like to see if a version could somehow relate more to our software.
We're split on how #11 and #12 speak to the functionality of what we're building versus the clean simplicity of #19 and #20.
