The Riverside Company has added Jacosoft, a Houston-based alert system software developer, to its portfolio company Emergency Communications Network. Jacosoft's emergency and mass notification system provides an instant communication solution for a number of applications, including natural disasters, weather alerts, man-made incidents and other time-sensitive notifications. ENC's communication platform performs similar services in all 50 states and Canada. Jacosoft's customer concentrations in Texas and North Carolina will strengthen ENC's presence in those localities. Riverside acquired the platform in October 2011.
