AI observability platform for model monitoring and explanation MoreLess

Fiddler AI is a company that provides a Responsible AI Platform designed to help organizations build and maintain trustworthy AI solutions. The platform offers a suite of tools for monitoring, explaining, validating, and analyzing machine learning models in production.

The company primarily serves data science and MLOps teams in enterprises that are deploying AI models at scale. These clients operate in various sectors, including financial services, healthcare, and technology, where the reliability and fairness of AI systems are critical.
