I haven’t extolled it too much here, but I’m a fan of what marimo has been doing in the computational notebook space. As a small, venture backed, startup it was relatively safe to root for them. Of course venture backed implies a certain space of outcomes and one of them came to pass. Marimo joined CoreWeave.
TL;DR Marimo is joining CoreWeave. We’re continuing to build the open-source marimo notebook, while also leveling up molab with serious compute. Our long-term mission remains the same: to build the world’s best open-source programming environment for working with data.
marimo is, and always will be, free, open-source, and permissively licensed.
I’m hopeful that this won’t severely impact marimo for at least two to three years. There’s a fair bit of underlying robustness and stability that could be added amongst the strong drive on features. Given similar acquisitions I’ve seen, beyond that timescale is a crapshoot. Blitzscaling startups or existing Big Tech organizations purposefully make acquisitions fundamentally different as they become further integrated. It’s sort of the point.
Of course some folks will be bent out of shape and declare “back to Jupyter!!” That’s reasonable, except from what I understand you can’t get to marimo from Jupyter.
Simon Willison puts the proper nuance on the current state of play
Give (sic) CoreWeave’s buying spree only really started this year it’s impossible to say how well these acquisitions are likely to play out - they haven’t yet established a track record.
