Marimo Inc.
Building the world's best open-source programming environment for working with data. Marimo is an open-source reactive notebook for Python that is reproducible, Git-friendly, deployable as a web app, and executable as a script.
Founding Story
Started nearly four years ago (around 2022) when Akshay Agrawal was motivated to create better tools for Python developers working with data. His experience researching and developing vector embedding methods in Jupyter notebooks, which were extremely frustrating due to hidden state, non-reproducibility, and poor version control, led him to create something better. Myles Scolnick joined as co-founder, and together they created marimo to blend the best parts of interactive computing with the rigor of traditional programming. The project was incubated for over a year with Stanford's SLAC Laboratory before being publicly launched on HackerNews in January 2024.

Business Model
Revenue Model
Open-source software with cloud-hosted notebook service (molab). Initially free to use with plans to offer paid tiers for enhanced compute resources and GPU access. After CoreWeave acquisition, revenue model includes integration with CoreWeave's cloud services.
Pricing Tiers
Core marimo notebook is free, open-source, and permissively licensed. Can be self-hosted and used without restrictions.
Cloud-hosted notebooks with reasonable usage limits. After CoreWeave acquisition, offering more generous free tier with larger instances, GPUs, and longer-lived sessions.
Planned paid tiers for GPU-accelerated compute services and enhanced resources through CoreWeave Cloud.
