Deepnote
Deepnote is a cloud-based, collaborative data notebook that reimagines the Jupyter notebook for teams. Founded in 2019 in San Francisco, it lets data scientists and analysts connect data sources, write Python, SQL and R, and work together in real time - like a Google Docs for data. In recent years it has leaned heavily into AI, adding an agent that can generate, edit and debug entire notebooks, and it went open source in 2025.
Ideaflow
Ideaflow is a Palo Alto-based AI company building an 'intelligence amplification' layer for knowledge work. Its flagship product is a notebook that augments your thinking as you type, letting people capture and stitch together fragments of information. The company has since expanded into team knowledge tools - Base, which surfaces context from Slack, meetings, and documents, and meeting intelligence - aiming to become an organization's collective memory. Founded around 2015 by MIT Media Lab designer Jacob Cole and Etherpad/Meteor veteran David Greenspan, it has raised roughly $11M in seed funding from First Round Capital, 8VC, StartX, Naval Ravikant, and Tim Draper.
