Deepnote, a collaborative data science notebook, announced it has raised $20 million in Series A funding. The round was co-led by Index Ventures and Accel, both doubling down on their Seed investments, with participation from Y Combinator and Credo Ventures. Existing investors include OpenAI's Greg Brockman, Figma's Dylan Field, Elad Gil, Naval Ravikant, Daniel Gross, and Lachy Groom.

Deepnote, founded in San Francisco in 2019, is a new kind of data science notebook that makes data science teams radically more productive. The company was founded around the idea that in order to solve the hardest problems in data science and machine learning, just adding more compute power wouldn't cut it.
