Who we are

We are a small group of true technology enthusiasts. We believe this separates us from a lot of other companies. We are not just trying to earn a buck, we really love what we do. Imagine having at your disposal a team that is at least as enthusiastic to build your software as you are, if not more. Imagine what difference passion makes. The attention to detail. The care for the project and its success. Rounded Square was founded for those of you who want partners instead of just contractors.
