About Us

Our aim at Polar Signals is to allow you to see what's underneath the iceberg. We firmly believe performance and reliability are key features of any software.

Fast software is more enjoyable and productive to use. This reflects itself in the numerous research findings, where users frequently quit sites that are slow, and the faster a system, the higher the conversion rate.

At Polar Signals it is our mission to allow everyone to build software that is fast, reliable and enjoyable to use.
