Bloomberg reported on Monday that Rémi Cadène, the former Tesla Autopilot researcher who ran the AI systems inside Optimus for roughly three years and then went to Hugging Face to build LeRobot, has come out of stealth with a Paris company called UMA. Short for Universal Mechanical Assistant. First product is Northstar. Version 0 of the prototype was designed and assembled in nine months by a nine-person team, which is a specific kind of flex only possible when the co-founders include the person who wrote most of the open source robotics stack the rest of the field is currently downloading.
UMA closed a $40 million seed round backed by Greycroft, Relentless, and Unity Growth. The angel list is where it starts to get interesting. Yann LeCun, Meta’s chief AI scientist, put in personal money. So did Datadog CEO Olivier Pomel, and Hugging Face co-founder Thomas Wolf. That is a small collection of people who tend to be right about which infrastructure companies are actually going to matter, and they picked this one before there is a product to buy. The other co-founders include Pierre Sermanet, formerly of Google DeepMind and NYU, and Simon Alibert, one of the original LeRobot engineers. This is a software-heavy founding team building hardware, which is either the right shape for this category or the wrong one, and everyone is about to find out which.
The strategic bet is Europe first. Cadène’s argument is that European labor costs are already high, the demographic curve is running the wrong way faster than in the US, and the continent has an industrial base dense enough to absorb the first meaningful number of humanoid units without needing to break into an American market where BMW is already deploying 40 Figure 03s at Spartanburg and Optimus is trying to ramp Fremont. UMA says it is in conversation with 50 potential customers across logistics, manufacturing, and healthcare, and wants pilot deployments running before year-end. Nothing about that timeline is impossible. Nothing about it is easy either.
What is worth watching here is not whether Northstar V0 works. It is a prototype. It is not shipping. What is worth watching is whether the LeRobot open source stack, which Cadène spent his Hugging Face years turning into de facto shared infrastructure for the field, gives UMA a real head start on the software side of humanoid work, which everyone in the category now agrees is where the actual moat lives. Rodney Brooks used to say that a robot is one third mechanical engineering, one third electrical engineering, and one third software, and the software is the hard third. UMA is starting from the third that most of the North American humanoid companies had to buy or steal. If that thesis holds, the interesting European humanoid company is not the one Elon Musk builds in Berlin. It is the one an ex-Optimus scientist is building in the Marais.
