SigScale is a Canadian startup that provides open source solutions for communications service providers. Founded in 2015, the company focuses on developing cloud native signaling solutions for virtualized core networks. Their flagship product is the 3GPP Online Charging Server (OCS) built with TM Forum Open Digital Architecture (ODA). SigScale distinguishes itself by engaging with communications service provider partners through sponsoring feature additions to their fully open source virtual network functions and offering ongoing subscription support services.
One of the unique aspects of SigScale's business model is their belief in license-free software and a commercial model that ties costs to the consumption of their resources rather than the subscriber traffic volumes of their partners. While the company has made significant strides since its inception, including establishing a strong presence in the Information Technology industry, there is no available public information regarding their last investment or associated investors at this time.
