Comet is a meta machine learning platform designed to help AI practitioners and teams build reliable machine learning models for real-world applications by streamlining and connecting the machine learning model lifecycle.

Comet provides a self-hosted and cloud-based meta machine learning platform allowing data scientists and teams to track, compare, explain and optimize experiments and models.

Comet was founded in 2017 by Gideon Mendels and Nimrod Lahav. The company is headquartered in New York, New York.


Comet delivers both in one ML development platform. Combining these two, previously distinct categories provides significant value and allows customers to iterate faster from early experimentation all the way to production.


Comet launched Comet Model Production Monitoring (MPM), a key innovation which enables organizations to track and monitor the quality of models. The company also created Comet Artifacts, for managing dataset versions across any step of the ML pipeline.


Comet has integrations with Amazon Sagemaker, Catalyst, GitLab, Google Vertex AI, Keras, New Relic, Pytorch, Scikit-learn, Spark NLP and Tensorflow. Comet currently serves over 150 customers, including Ancestry, Cepsa, Etsy, Uber, WorkFusion and Zappos.
