Ubitium raises $14M to build universal processor for Physical AI

German semiconductor startup Ubitium has announced USD 14 million in new seed funding. The round was led by Ibex Investors, with participation from OpenOcean, existing investors including KBC Focus Fund, Runa Capital and Inflection, and Florian Seibel, co-founder and co-CEO of European defence technology company Quantum Systems, investing personally. 

It brings Ubitium’s total seed funding to USD 18 million since the company was founded in 2024, the company said in a press release.

According to Ubitium, autonomous machines need three kinds of computing to work together so they can perceive, think and act in the real world. The company says it is building one universal processor to replace the stack of specialised chips often stitched together to do that work today.  

“Physical AI machines bring a whole new set of computing challenges, and the inference isn’t the hardest one,” said Hyun Shin Cho, CEO and co-founder of Ubitium. “Sensing the real world and controlling the machine in it are just as hard, and today those still run on separate chips. We built one Physical AI processor that does all three, proved it in silicon in a year, and this funding turns it into a product.”

Ubitium plans to tape out its first commercial processor, the UB410 with 4,096 processing elements, and deliver evaluation units in 2027.  

“An autonomous machine operating in the real world must keep working when communications are unavailable. It has to process its surroundings, make decisions and control itself on board, within strict limits on power and weight,” said Florian Seibel, co-founder and co-CEO of Quantum Systems. “Today that means integrating a stack of chips that were not designed to work together, and every one of them costs weight, power and integration time we don’t have. Ubitium is building the one processor that does that whole job. That’s why I invested.”
