SignalWire, a pioneer in software-defined telecommunications infrastructure, announced that T-Mobile Ventures has participated in its Series B round.

In June 2021, SignalWire had secured $30 Million in the first closing of a Series B round, led by Prosperity7 Ventures. Round B is now complemented by a second closing with the investment by T-Mobile Ventures.

With SignalWire, developers can easily build Web and mobile applications that integrate hundreds of simultaneous video, voice and messaging streams in the cloud for streaming back in a single feed to large audiences.
