Calix Named Among Fortune 100 Best Companies to Work For as Agentic Leadership Advances

Customer partnerships drive a winning culture at Calix as the company leads with an AI‑native platform for service providers of all sizes

SAN JOSE, Calif.--(BUSINESS WIRE)-- Today, Calix, Inc. (NYSE: CALX) announced it has ranked 85th on the Fortune 100 Best Companies to Work For® 2026 list. The listing also ranks Calix 21st in Best Large Workplaces in Tech, 18th in the Bay Area, and 67th for Parents.

This recognition reflects Calix’s award-winning, customer‑first culture and accelerating business momentum. Founded 26 years ago to serve communications service providers (CSPs), Calix evolved over the past 15 years into a software‑led platform company, developing Calix Cloud® to enable success for its customers’ network operations, customer service, and marketing workflows. That platform transformation is helping CSPs become communications experience providers (CXPs) and drive measurable outcomes, including Net Promoter Scores℠ (NPS®) as high as 94, higher average revenue per user (ARPU), and lower operating costs.

Calix is meeting the AI opportunity from a position of long‑term readiness. With the launch of the AI-native Calix One™ platform in February 2026, all customers are now fully migrated to Google Cloud—preparing every customer to leverage full agentic capabilities. Built on a unified foundation of network access, managed services, cloud, and AI‑enabled workflows, Calix One is now enabling customers to deploy agentic capabilities to accelerate operational transformation and deliver exceptional subscriber experiences at scale.

At Calix, an unwavering focus on enabling customers to transform their businesses—so they can compete and win—continues to shape how the company operates, innovates, and evolves its culture. Calix supports long‑term performance for employees through programs such as no‑internal‑meeting days and clear norms around unplugging, while a fully remote model enables the company to recruit top talent regardless of location.

This Fortune recognition builds on a strong 2026 run of culture-related honors for Calix, including:

Michael Weening, president and chief executive officer at Calix, said: “We have invested more than $2 billion over 15 years to build an AI‑native platform that enables communications service providers of any size to compete and lead in their markets. We began our agentic AI journey in late 2023 with a clear understanding: Nothing worth doing well is easy. As I have said, AI is not fairy dust. Real results come from doing the hard work—together—with team members, customers, and partners committed to execution. This recognition from Fortune belongs to our employees and reflects the trust our customers and partners place in us as we continue building for the long term.”
