SignalWire's usage-based pricing model features minimal markup on the carrier services accessed using their APIs, such as per-minute and per-SMS charges, a move that could cause major disruption in a space occupied by API providers whose bottom lines depend on comfortable margins on these same services. SignalWire Cloud allows developers of all skill sets to access the underlying power of FreeSWITCH technology via an elastic cloud platform. Its robustness, however, can be a barrier to developers without specific knowledge of communications technology, and it requires significant resources to deploy and manage. It lays claim to the largest install base and most powerful feature set of any enterprise-grade communications platform.

Developers should be limited only by their imaginations, not by their budget for minutes and messages or development cycles required to solve problems we've spent the past 15 years solving." SignalWire's open-source project began at ClueCon in 2006, and rapidly grew from a single voice-over IP call to millions of lines of code. SignalWire is the next phase in our goal to democratize communications by making this infinitely powerful technology accessible to anyone with an idea. Today at ClueCon, an annual telecom developers conference in Chicago and birthplace of enterprise open-source communication software, SignalWire CEO Anthony Minessale reiterated the company's mission, "We've built the technology core for the world's most technically demanding and globally scaled communications products and services. The funding will be used to accelerate the development of SignalWire's Cloud communication platform, a new offering that allows developers to embed voice, messaging, and video capabilities into applications using advanced real-time APIs.

Storm Ventures led the round joined by institutional investors Samsung NEXT and Sequoia Capital (Sequoia Scouts) and by fellow Silicon Valley OGs Erik Yang (CEO, Zoom), Dean Drako (Founder, Barracuda Networks), Yahoo's Jerry Yang (AME Cloud Ventures) and Ron Neuenberger (AngelFire). SignalWire, Inc., the Original Geeks of software-defined telecommunications and developers of the number one open-source enterprise communication platform, FreeSWITCH, today announced the closing of an $11.5 million series A funding round.
