Christopher Jennison

Summary

Principal engineer and engineering leader with 13+ years of experience building AI platforms and the teams that run them. At Microsoft, I lead engineering for all of Copilot Studio's UI services, used by more than 230,000 organizations including 90% of the Fortune 500, and my team was one of the founding teams behind the new Copilot Studio experience built on the GitHub Copilot harness. I also built an internal AI agent platform that turns weeks of incident, accessibility, and compliance work into days. Before Microsoft, I ran a 25-engineer organization at Nuance and led engineering for the Nuance Mix UI, a conversational AI platform with $200M in annual recurring revenue.
