The provider notes it powers more than 40 million active residential and small business locations with its cloud hosted services through more than 275 CSPs across the Americas, Europe and Japan.

“As a founder and entrepreneur, I not only look for great technology that customers love, and a talented team, but also the opportunity to create an entirely new category,” commented Magdalena Yesil. “Plume has created a new category that is redefining consumer experiences in smart spaces, and I’m thrilled to be a part of this ambitious group of people.”

Plume leverages OpenSync, an open-source framework that comes pre-integrated and supported on the leading silicon, CPE, and platform SDKs.

“I’ve long shared Fahri’s vision, and appreciated Plume’s ambitions in reconstructing residential and small business service bundles,” said Tony Werner. “Today, over 95% of home devices, ranging from personal computers, e-readers and tablets to the exploding number of IoT hardware, connect to broadband over WiFi. The one thing they all have in common is the critical need for high performance, reliable and consistent connectivity over an unlicensed, wireless spectrum. Plume is revolutionizing connectivity and the smart home experience with an open platform, hardware agnostic approach. I am excited to continue partnering with Fahri, and help the Plume team achieve their goals in transforming smart spaces globally.”

To help fuel the accelerating expansion of the global software defined network controlled by its cloud control plane currently managing more than 1.6 billion unique client devices, the provider notes it raised $540 million over two rounds of funding in 2021 from Insight Partners and SoftBank Vision Fund 2.
