QuantumShift Communications

Series C in 2001
A fundamental shift has occurred in communications services. The change affects a company's ability to grow. It impacts revenues and profitability. It determines how well an enterprise can serve its customers, work with its partners, support its employees. Yet, surprisingly, it is often overlooked by top executives. Quite simply, communications services have become mission critical. Voice, data, cellular, local, long distance, Internet access, DSL, VPN, calling cards, PBX, voice mail, unified messaging, network management, broadband access – these services are the lifeblood of any enterprise that wants to tackle global markets, innovate at Internet speed, and engage in the continuous transformation that is demanded by today's competitive environment. Unfortunately, the process of procuring and managing them has become increasingly chaotic and costly. Communications has become the third largest operational expense in mid-size companies. Even at that expense, much of it remains hidden, scattered throughout the enterprise, distributed among the business units, duplicated by mergers and acquisitions. Communications managers find themselves inundated with a mind-numbing array of service options, overwhelmed with literally boxes of bills, and continually asking for more headcount. Managing these multiple vendors diverts critical resources away from core business initiatives. Billing errors reduce funding for research, product development, marketing, and sales. Outages and downtime undermine relationships with customers and partners. With so much at stake, a comprehensive, single-source solution is needed for procuring and managing communications services.
