Thanks for your logo submission! Our team really liked the cleanliness and simplicity of what you provided. Having more of a 3D effect was an interesting take. But we aren't positive how it will look on the printed planners that we sell our clients to utilize on a day-to-day basis for tracking their projects. Perhaps you could provide some other options that resemble this one? The boxed "C" also reminded me of another company's logo I always liked (www.effectiveui.com). Perhaps you could incorporate some of those design features into a few more ideas. Maybe replacing the "UI" part with "PM" for project management? Just an idea.
Here is some additional information on what Centro does. We provide project management systems primarily to the architecture industry. We send our clients project planners and personal planners to track their projects step-by-step in order to optimize success. While there are numerous project management companies in the industry, our solutions really try to simplify the process to keep architects focused more on the high-level success of their projects, not the minute details.
Hopefully this description helps clarify what we are looking for in a logo. Something that expresses simplicity, modernness, streamlined, basics, efficiency and quality. Thanks again!
