We believe in simple elegance - clean, stylish, approachable, and professional all at the same time. We do not want any cartoons, clip art-looking logos, or anything childish. Colors are fine, as long as they aren't overwhelming or 'loud'.
We also want to avoid the obvious designs, like a giant spring or the change of seasons, as well as flipped/reversed letters, etc. Images are fine, but we're open to a completely typographical solution. In addition, while we are a web-based software as a service, we don't want the logo to be a cliche web 2.0 design.
Keep in mind we're a web-based service, but we'll also use the logo for business cards and related items.
The name is two words and should not be mushed together - i.e., Spring Metrics, *not* SpringMetrics.
Some elements we're trying to convey....
answers (we provide answers, not just data points)
action (answers you can take action with)
results (analytics tools give you data, not answers with which you can take action to get results - more conversions)
