Based in Denver, Colorado, Radius Alert Systems, Inc. (RAS) is a smart phone app development company that designs, produces and markets mobile applications and hardware.

We make products that notify our customers when their valuables are leaving their radius or perimeter.  Our goal is to make our customers aware of potential loss before it happens.  Other companies may focus on retrieval of already lost items; we plan to prevent loss in the first place.

Our most recent product, LassoTag, is a monitoring technology to assist people in their everyday lives by making it simpler than ever to track, organize and monitor valuables through a smartphone.
