Code Ocean is a New York-based B2B SaaS platform that makes computational research reproducible, traceable and collaborative. Its flagship Compute Capsule bundles code, data and the exact software environment together so an analysis runs identically today or years from now. Used by pharma, biotech and leading research institutes, and integrated with journals like Nature and IEEE, Code Ocean is building a trusted virtual lab where both scientists and AI agents can run real analyses with full version control, lineage and compliance.
marimo is a San Francisco company building an open-source reactive Python notebook that replaces the error-prone JSON of Jupyter with pure Python files. Cells form a dataflow graph, so changing one variable automatically re-runs the cells that depend on it - notebooks are reproducible, git-friendly, deployable as apps, executable as scripts, and can even run entirely in the browser via WebAssembly. Founded in 2022 by Akshay Agrawal and Myles Scolnick, marimo raised a $5M seed in 2024 and joined CoreWeave in October 2025 while keeping the notebook free and permissively licensed.
