Calix completes Calix 3.0 platform migration on March 26, moving all customers to AI-native infrastructure as it targets 15% annual growth through 2028

Calix finished a 2.5-year overhaul on March 26, moving all its customers onto Calix 3.0—an AI-native platform built to replace the old system where the company had to run two separate cloud environments. This required replacing 80% of Calix's staff and a shift away from hardware-only business starting in 2019; the company grew revenue from $400 million in 2019 to $1 billion in 2025 as a result.

Calix 3.0 processes a petabyte of data daily and now delivers AI agents (AI tools that make decisions and act on their own) instead of static reports—starting with assistant tools in Q1, then expanding to automated workflows for customer acquisition, upsell, churn prevention, and support in Q2. Customers like Lumos Fiber expanded service builds significantly without hiring more customer care staff, boosting their Net Promoter Score from the high-70s to 84.

For broadband and fiber service providers, Calix agents are built to handle labor-intensive tasks: Tombigbee Fiber's CEO said AI could multiply his small marketing team's output by more than 10x, while Calix itself built hundreds of internal agents to cut handoffs and rework. This matters because rural fiber operators and regional broadband companies face chronic staffing shortages—agents let them compete with larger carriers without proportional headcount growth.

Calix switched strategic cloud partnerships from Amazon to Google, citing Amazon's competitive threat to its service-provider customers, and is targeting new markets in multi-dwelling units (MDU), hospitality, and global tier-one carriers. The company commits to 15% revenue growth in 2027 and 2028, though it flagged near-term margin pressure from memory cost surcharges in 2026.
