When UFO Lands! Analyzing User Feedback During a Massive Customer Migration
About the talk
When two companies merge, migrating tens of millions of customers onto a single platform is a monumental challenge. In our migration, a decision to move fast—skipping the external beta—left us without the usual qualitative insights from early testing. Our support call queues were unprepared for a new tech stack, and a small canary cohort meant issues went unflagged. Suddenly, the only real signals came from in‐product feedback and uninstall surveys.
To overcome this, we adopted a shift‐right approach, building a lightweight, AI‐driven solution using LLMs. We automatically ingest and categorize real‐time user feedback, then deliver interactive dashboards for testers—scaling to the demands of a live, high‐volume environment. Best of all, this process is simple and replicable in any cloud, with a practical checklist you can immediately apply to your own projects.
In our talk, we’ll share the real‐world case study of how we developed the “User Feedback Overview” LLM‐powered feedback evaluation and monitoring system, ultimately reducing blind spots and improving troubleshooting speed during a massive customer migration. Join us to see how real‐time feedback can transform your testing strategy and delight your customers—even under extreme pressure.
