Spantree is a boutique, Chicago-based consultancy delivering intelligent, high quality software solutions for the web. In particular, we understand the challenging nature of working with legacy code. We prefer an evolutionary and iterative approach to software design, focusing on high-value enhancements in favor of wholesale reengineering. We evangelize testing early in the cycle to ensure software quality and boost developer productivity.

We believe that building great software should be fun and engaging. We also believe that it's rare to know all the answers to the most important questions upfront. Thus, we focus on short cycles of discovery, invention, definition, application and revision at each feature milestone.

We communicate with client teams everyday: face-to-face, over the phone and on the Web. We'd love to chat about your project.
