Calix, Inc.

Calix, Inc. is a telecommunications company that provides cloud and software platforms, systems, and services to broadband service providers (BSPs) globally. Founded in 1999 and headquartered in San Jose, California, the company's mission is to connect everyone and everything by enabling BSPs to simplify their operations, innovate, and grow their businesses and the communities they serve.

Calix offers a comprehensive portfolio of solutions, including its AI-native Calix One platform, which encompasses Calix Cloud (Engagement, Operations, and Service Clouds), Revenue EDGE, and Intelligent Access EDGE. The company also provides SmartLife managed services, such as SmartHome, SmartTown, SmartBiz, and SmartMDU, which deliver residential cybersecurity, parental controls, managed Wi-Fi, and services for small businesses and multi-family properties. Additionally, Calix supplies Wi-Fi systems under the GigaSpire and GigaPro brands, alongside various access network technologies like 10G-PON, NG-PON2, and 50G-PON.

Under the leadership of President and CEO Michael Weening, Calix has been recognized in Newsweek's "Greatest Workplaces in Tech 2026" for its human-centric agentic innovation. The company recently enhanced its SmartMDU platform with new user management and Wi-Fi suspension features and secured FCC approval for its gateway appliance portfolio. However, Calix is also currently facing class-action lawsuits alleging securities fraud related to its first-quarter 2026 margins and memory component purchasing.
