Mona

Mona is an AI monitoring and observability platform that gives data science and ML engineering teams end-to-end visibility into production AI systems. It automatically monitors model performance across granular data segments, detects data drift and concept drift, and uses Common Thread Analysis to surface root causes of misbehavior. Mona supports any model type — from traditional ML to generative AI including LLMs — and integrates with New Relic for infrastructure correlation. Founded in 2018 by ex-Google and McKinsey veterans, Mona deploys on-premise (including air-gapped) or in the cloud. Note: the website currently shows an under-construction page.
