Justin R. Greenbaum
Founder of Greenbaum Labs. Customer operations and experience executive.
Justin R. Greenbaum spent twenty years at Comcast moving from frontline technical support to Vice President, leading national and global customer operations across customer care, technical support, digital service and customer intelligence, global partner operations and high-trust functions.
Greenbaum Labs turns that operating experience into methods and working systems: organizational diagnostics, AI systems for customer intelligence, and measurement of how brands appear in AI-generated answers. The Lab is the build environment: experiments, benchmarks, methodology decisions, and the reasoning behind them, published as they happen.
His professional background, executive record, and current focus live on his personal site.
The Lab is the practice’s research and build environment. The work is published so the methods can be examined, challenged, and reproduced.
