Plume, the software-as-a-service company that powers intelligent home connectivity and digital services for communications providers, has raised $300 million in new funding to accelerate the expansion of its cloud-based platform and meet growing demand for AI-driven smart home services. The financing values the Palo Alto, California-based company at approximately $2.6 billion and strengthens its position as one of the leading providers of software for internet service providers worldwide.

The funding round was led by SoftBank Vision Fund 2. The investment followed Plume’s earlier $270 million Series E financing led by Insight Partners, which valued the company at $1.35 billion and brought its total equity funding at that time to $397 million. The latest capital reflects continued investor confidence in Plume’s strategy of delivering cloud-managed connectivity, cybersecurity, and smart home services through communications service providers rather than directly to consumers.

Founded in 2015 by Fahri Diner, Bill Kish, and Adam Hotchkiss, Plume has built a software platform that combines adaptive Wi-Fi management, artificial intelligence, cybersecurity, parental controls, motion awareness, and network optimization into a single cloud-based service. Rather than focusing solely on wireless hardware, the company enables broadband providers to offer continuously improving digital services that optimize home networks in real time through cloud intelligence.

Plume’s platform analyzes billions of connected device interactions to optimize network performance automatically while identifying connectivity issues before they affect users. Its cloud-native architecture allows internet service providers to deploy new capabilities without requiring customers to replace networking hardware, enabling continuous software improvements across millions of homes.

Since its launch, Plume has expanded rapidly through partnerships with communications service providers across North America, Europe, Asia, and the Middle East. The company’s platform serves tens of millions of households worldwide and manages more than one billion connected devices, providing internet providers with tools that improve customer experience while reducing technical support costs.

The newly raised capital will support continued investment in research and development, engineering, global sales, marketing, and strategic partnerships. Plume also plans to expand its international presence while introducing additional AI-powered services for broadband operators and connected homes. The company believes the growing number of connected devices within households creates increasing demand for intelligent software capable of managing complex home networks automatically.

Unlike traditional networking companies that generate revenue primarily through hardware sales, Plume operates as a subscription-based software platform delivered through broadband providers. This recurring revenue model enables continuous feature updates while allowing communications companies to differentiate their broadband offerings with advanced digital services including cybersecurity, access controls, device prioritization, performance analytics, and motion sensing.

Artificial intelligence plays a central role throughout Plume’s platform. The company continuously analyzes network conditions, connected devices, user behavior, and application performance to optimize connectivity automatically. These capabilities allow broadband providers to proactively identify problems, reduce service disruptions, improve customer satisfaction, and lower operational expenses through predictive network management.

Investor support from SoftBank Vision Fund 2 follows strong commercial momentum as communications providers increasingly seek software platforms capable of generating recurring service revenue beyond internet access alone. Earlier backing from Insight Partners further demonstrated confidence in Plume’s long-term vision of transforming broadband providers into digital service platforms through cloud software and artificial intelligence.

The broader broadband industry continues evolving as households connect increasing numbers of smart televisions, gaming systems, security cameras, appliances, sensors, and mobile devices. Managing these increasingly complex home environments has become a significant challenge for both consumers and internet service providers. Plume’s cloud-managed platform addresses these challenges by automating network optimization while introducing value-added services that enhance security, privacy, and overall user experience.

The company has also expanded beyond Wi-Fi optimization into services supporting cybersecurity, device protection, parental supervision, motion detection, consumer analytics, customer support automation, and network intelligence. These capabilities help communications providers improve customer retention while creating additional recurring revenue opportunities through premium digital services.

With fresh funding led by SoftBank Vision Fund 2 and following its previous investment from Insight Partners, Plume plans to continue expanding its AI-powered software platform across global broadband markets. As internet service providers increasingly compete on customer experience rather than connectivity alone, the company aims to strengthen its position as a leading provider of cloud-managed networking intelligence that enables smarter, safer, and more personalized connected home experiences.
