SignalWire Secures $30 Million Series B led by Prosperity7 Ventures to Build Infrastructure for Telecom 2.0

Elastic cloud platform to enable the next generation of unified communications tools.

PALO ALTO, CALIF. - June 2, 2021 - SignalWire, a global leader in software-defined telecommunications technology, announced today that it has raised $30 Million in a Series B round to accelerate the creation of the next generation of unified cloud communications tools. Led by Prosperity7 Ventures, and joined by Storm Ventures, Samsung NEXT, Jerry Yang (AME Cloud Ventures), and Dean Drako (Barracuda Networks), the round brings SignalWire’s total funding to $41.6 million to date.

Since its inception, SignalWire’s singular focus has been on the democratization of communications applications, and it is now building the infrastructure for Telecom 2.0, the next generation of modern telecommunications technologies. The company’s Series B round will be used to ramp up the development of a complete, flat, and unified development layer and cloud platform upon which the next generation of communications applications are built.

With a focus on ease of integration of multi-channel infrastructure including voice, video, and messaging, SignalWire’s core technology allows developers to seamlessly integrate APIs and SDKs into products that consume fewer engineering, bandwidth, and processing resources. With the increasing importance of video-based communications, SignalWire’s expertise in the integration of Multipoint Control Unit architecture into elastic cloud infrastructure positions the company to continue to lead in a future populated by end-users with a diverse array of use cases, access to networks, and devices.

“The pandemic has brought into sharp relief the need for communications technologies that are scalable, secure, customizable, and fast-to-market for developers. For end-users, and especially those using video, the experience needs to be smooth, stable, clear, and not a drain on network or compute resources” said Anthony Minnesale, Co-Founder and CEO of SignalWire. “The good news is that we’ve been working toward that exact vision for more than 15 years, and have designed the roadmap for its further implementation.”

Known as the “Original Geeks of software defined-telecom,” SignalWire’s team has been developing communications platforms since 2006, including FreeSWITCH, the most widely deployed open-source telecommunications tool in the world.
