The use case: how Rox deploys Snorkel AI
Rox builds an AI-powered sales platform with agents that write personalized outbound emails. It uses Snorkel's evaluation suite to score its LLM-as-a-judge against human experts, improve the judge's alignment, and use it to find and fix errors in its outbound email model before shipping.
