Tombigbee is creating secure agentic workflows to build on the extraordinary member loyalty reflected in their 92 NPS—earned by providing experiences like SmartTown for first responders, Friday Night Fiber for high school football stadiums, and Bark digital safety for children and families

Today, Calix, Inc. (NYSE:CALX) announced that Tombigbee Fiber, LLC (Tombigbee) is leveraging their investment in the AI-native Calix One™ platform to begin building secure agentic workflows with Calix Agent Workforce™ Cloud. These collaborative AI workflows will act as a force multiplier for an experience-led growth model that has delivered exceptional results over a seven-year partnership with Calix—during which Tombigbee achieved a Net Promoter Score℠ (NPS®) of 92 and positive cash flow in just two years.

Working hand in hand with award-winning Calix Success™ and building on 26 years of service provider workflow expertise embedded in the Calix One platform—which processes more than a petabyte of data daily and executes over 4.3 billion workflows and operations annually—Tombigbee has moved quickly to lay a strong foundation for operationalizing secure agentic AI. Successful early results across marketing, customer support, and network operations have demonstrated value in accelerated knowledge sharing and reducing operational complexity. As they advance, their secure agentic workflows will help Tombigbee turn insights into action even faster—providing their team with expert knowledge, strategic guidance, and contextual intelligence so they can deepen member engagement and scale highly personalized outreach.

Scott Hendrix, chief executive officer at Tombigbee Fiber and Tombigbee Electric Power Association, said: "While we are still in the early stages of our Agent Workforce Cloud journey, we are already seeing meaningful value from its ability to put expertise at every employee’s fingertips. It is helping our teams learn faster, better understand complex information, and navigate subscriber interactions with greater confidence. We have been impressed by how quickly our employees have embraced agentic AI, and we are excited about the role this transformative technology can play in advancing our mission."

With Agent Workforce Cloud, Tombigbee is building on their success, leveraging Calix Engagement Cloud and Business Insights to identify opportunities for delivering meaningful experiences that reflect member needs. Founded in 2019 to bring fiber connectivity to rural Mississippi, Tombigbee partnered with Calix to rapidly adopt, deploy, and manage world-class experiences that radically improve life for their communities. Their initiatives include:

Helping save lives with SmartTown® by delivering free, secure Wi-Fi for first responders—including police, emergency medical services, firefighters, and rural healthcare providers—in areas with limited cellular coverage.
Transforming community spaces with free, public Wi-Fi—expanding SmartTown to parks, downtown districts, libraries, and community centers while enabling secure roaming beyond the home.
Connecting nine high school football stadiums through the "Friday Night Fiber" initiative, bringing public SmartTown Wi-Fi to the cultural heart of rural Mississippi.
Protecting children and families on social media and online with Bark digital safety monitoring, advanced home cybersecurity, and parental controls included for every residential subscriber via SmartHome™.

Because every SmartLife™ managed service runs on Calix One, Tombigbee can rapidly launch new services, manage them through a single operating model, and continually innovate without adding operational complexity. This platform approach enables the provider to reduce operational costs, grow member loyalty, and reinvest profits in the communities they serve.

Hendrix added: "We built Tombigbee Fiber because rural Mississippi communities deserve the same opportunities, protection, and connected experiences available anywhere else. Over the last several years, we’ve learned that, when we invest in experiences that solve real problems, our subscribers respond and our business grows stronger. Calix has helped us turn that belief into action, and that’s why we trust them to be our innovation engine."

Michael Weening, president and chief executive officer at Calix, said: "As Scott Hendrix has said, doing good for people is just the right thing to do. Agentic AI represents a massive opportunity for them to augment the expertise of their teams and amplify their impact, so they can continue to reinvest in their communities. With the secure, AI-native capabilities of the Calix One platform, Tombigbee can now dramatically accelerate personalized subscriber experiences at scale—while reducing operational complexity and scaling the expertise of their team. That is how to compete to win while growing a brand that subscribers love, as evidenced by their outstanding 92 NPS. We are honored to support their success."
