Congruency

Series C in 2000
Founded in 1998, congruency, Inc. is a premier provider of hosted IP telcom services and the first company to define and lead the Communications Application Service Provider (CASP) market. A CASP is a new type of ASP that permits Internet-based delivery of a full range of communications services, from voice, to data, to targeted content personalized to IP telephones and Internet appliances. Based in Rochelle Park, NJ with development offices in Petach-Tikva, Israel, congruency has developed a "next generation," true Internet voice networking platform that operates with all broadband access technologies. The system uses an architecture incorporating Voice-over-IP, patent-pending technology, ITU/IETF standards and proprietary methods. The result is high quality, traditional and advanced voice communication services over broadband data networks. The network is designed to work with new Internet telephone appliances such as congruency's own i.Picasso© family of phone appliances -- which allow true IP telephony on the business desktop. These IP appliances have the simplicity, familiarity and feel of traditional telephones, but offer advanced Internet capabilities including the delivery of new and easily-customized communications services. The demand for these devices is expected to grow exponentially. Phillips Infotech predicts that over the next four years, more than 10 million business telephone lines will convert to IP. congruency markets these services to Competitive Local Exchange Carriers (CLECs), Internet Service Providers (ISPs), and Building Local Exchange Carriers (BLECs). Due to rapidly increasing competition within their markets, service providers are being compelled to find ways to enhance their products and services. Most currently, they offer similar low-margin commodity transport services, limiting their revenue-generating opportunities. In addition, service providers suffer from customer churn, due to a market in which all providers sell the same basic services. congruency's Communications Network offers a new world of opportunities for CLECs, ISPs, and BLECs by allowing them to sell a host of new, quality, IP services to their customers, without investing in expensive equipment and resources. Through its advanced services, congruency makes it possible for service providers to easily move from a low-cost transport, or a "free" telephony model to a "value-added services" business model, permitting them to generate new revenue streams. In addition, new "value-added" services permit service providers to build customer loyalty, and significantly reduce customer churn and low-profit margins that now characterize their marketplace. As the leader of CASP, congruency is prepared to meet the future needs of the marketplace for IP voice, data and targeted content.
