Its platform enhances connectivity, performance, and security through a software-defined network (SDN), operating the world's largest SDN managing over 1.2 billion devices across 35 million households by October 2021. The company had added 13 million new households and 350 million devices in the two quarters prior, along with over 60 new CSP customers, averaging 2.2 million new home activations monthly. On October 12, 2021, Plume closed a $300 million Series F funding round led by SoftBank Vision Fund 2, which contributed about 90% of the investment, bringing total funding to $697 million and post-money valuation to $2.6 billion—nearly double the $1.35 billion from its prior $270 million Series E in February 2021 led by Insight Partners. Other investors include Charter Communications, Comcast Cable, Foxconn, Jackson Square Ventures, Liberty Global Ventures, Qualcomm, Samsung, and others. The round was a minority equity investment, selected partly for SoftBank's strategic alignment in cloud, AI, data, and global telecom influence. Funds will support R&D for advanced network solutions and AI features, sales and marketing expansion, new partnerships, acquisitions, headcount growth, and enterprise-grade connectivity services, including eyes on 5G fixed wireless access (FWA). Plume's consumer-first approach reinvents services for smart spaces, moving beyond hardware-coupled legacy models to enable rapid scaling of experiences for CSPs. SoftBank's Nagraj Kashyap joined the board, highlighting Plume's role in reliable connectivity amid rising digital dependence post-pandemic. By late 2021, Plume had reached unicorn status, with rapid growth fueled by carrier deals and platform scale. |
