LIVINGSTON – Cloud computing provider CoreWeave Inc said on Thursday it has agreed to acquire Marimo Inc, the creator of an open-source, AI-native notebook for Python, as it builds out its suite of tools for artificial intelligence developers.
The acquisition aims to integrate Marimo’s reactive development environment into the CoreWeave Cloud, creating a more unified platform for the entire AI lifecycle, from training models to deploying them at scale.
CoreWeave, which styles itself as “The Essential Cloud for AI,” has been on an acquisition spree to consolidate its position in the competitive AI infrastructure market. The company recently announced deals for Weights & Biases, OpenPipe, and Monolith AI.
“This is about supporting the open-source community and unlocking the pace of innovation that modern AI demands,” said Brian Venturo, co-founder and chief strategy officer of CoreWeave. He stated the goal is to create “the most complete environment for AI development, from prototype to production.”
Marimo’s flagship product is an open-source notebook designed to offer a reproducible and git-friendly programming environment for data and AI workloads, addressing common challenges with traditional notebooks.
“We created marimo because we believed that Python developers deserved a dramatically better programming environment for working with data,” said Akshay Agrawal, co-founder and chief executive officer of Marimo. “Joining CoreWeave lets us double down on that vision, and execute on it at an even greater scale.”
CoreWeave said the Marimo open-source project will remain freely available and that its development will continue, guided by community collaboration. The financial terms of the deal were not disclosed.
Morgan Stanley served as the exclusive financial advisor to Marimo.
