Calix, Inc. has been ranked 85th on the Fortune 100 Best Companies to Work For 2026 list. The company also placed 21st in Best Large Workplaces in Tech, 18th in the Bay Area, and 67th for Parents.
This Fortune ranking reflects Calix’s award-winning, customer-first culture and its accelerating business momentum. Founded 26 years ago to serve communications service providers (CSPs), Calix has evolved over the past 15 years into a software-led platform company with Calix Cloud enabling success in network operations, customer service, and marketing workflows.
The platform transformation helps CSPs become communications experience providers (CXPs), delivering measurable outcomes such as Net Promoter Scores 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, every customer is now fully migrated to Google Cloud and prepared to leverage full agentic capabilities. Built on a unified foundation of network access, managed services, cloud, and AI-enabled workflows, Calix One enables customers to deploy agentic AI to accelerate operational transformation and deliver exceptional subscriber experiences at scale.
At Calix, an unwavering focus on enabling customers to transform their businesses continues to shape company operations, innovation, and culture. The company supports long-term employee performance through programs such as no-internal-meeting days and clear norms around unplugging, while its fully remote model allows recruitment of 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.”
