Ubitium raises $14M seed to put physical AI on one chip

Ubitium, the Düsseldorf startup designing a universal RISC-V processor, has raised $14M in new seed funding led by US firm Ibex Investors to take its 4,096-core UB410 chip to tape-out, with evaluation units due in 2027.

Below, I lay out the round, the architecture behind it, and why a US cheque landing on a German cap table is the detail worth sitting with.

A new lead and familiar names on the cap table

The round, announced on 13 October, brings Ubitium’s total seed funding to $18M since the company was founded in 2024. Ibex Investors led; OpenOcean came in as a new backer; and the three funds that co-led the $3.7M first seed in November 2024 – Runa Capital, Inflection and KBC Focus Fund – all returned.

There is one more name on the list, and it matters: Florian Seibel, co-founder and co-CEO of drone maker Quantum Systems, invested personally. “Ubitium is building the one processor that does that whole job,” Seibel said in the announcement.

The money has a single destination: getting the UB410, the company’s first commercial processor, through tape-out and into customers’ hands as evaluation units in 2027. “Ubitium is truly hardware at the pace of software,” said Jeffrey Peters, partner at Ibex Investors.

One array where a shelf of chips used to sit

Physical AI is the machine half of the AI boom: robots, drones, vehicles and industrial equipment that have to sense the world, run inference on what they find and control motors and actuators in real time. Today each of those jobs typically runs on its own specialised chip, and the data shuffling between them adds cost, latency and software complexity.

“Physical AI machines bring a whole new set of computing challenges, and the inference isn’t the hardest one,” said CEO and co-founder Hyun Shin Cho in the announcement. “Sensing the real world and controlling the machine in it are just as hard, and today those still run on separate chips.”

Ubitium‘s answer is a single reconfigurable array of processing elements that allocates compute dynamically to whatever the workload needs, paired with unified memory and the standard RISC-V toolchain. The claim stopped being a slide this year: the UB108, a first chip with 256 processing elements manufactured on Samsung’s 8nm process, has demonstrated signal processing, AI inference and real-time control on the same array.

Co-founder and CTO Martin Vorbach has spent more than three decades on reconfigurable computing, and the team behind him claims 17 granted patents and silicon experience from Intel, Nvidia, Apple and Texas Instruments, per the announcement. The UB410 scales the proven array to 4,096 processing elements, aimed first at high-resolution radar and audio systems, with autonomous machines such as drones as the target for the full architecture.

A $2.3bn market compounding at 31%

The instruction set Ubitium is betting on is no longer a research curiosity. The global RISC-V market was worth $2.3bn in 2025 and is projected to reach $34.7bn by 2035, a 31.3% CAGR for 2026-2035; Europe accounted for roughly $473M of the 2025 total and is forecast to grow slightly faster, at 31.8% (Global Market Insights, August 2026).

European chip rounds in our fundraising data give the amount its scale. EUCLYD raised a €200M+ Series A in September with Samsung among four co-leads; iPronics closed a $125M Series B for photonic networking the same month. Against those, $14M is a modest cheque – but it is buying seed-stage silicon that already works, not an architecture on slides. Working first silicon this early is the fact that separates this round from most seed-stage chip stories.

What a US cheque in Düsseldorf signals

So why does the lead investor’s passport matter? Because the pattern keeps repeating: we fund Europe’s deep-tech seeds, then watch the conviction rounds get priced abroad. Ubitium’s first seed was co-led by three European funds; the bigger follow-on was led from the US, with Belgium’s KBC Focus Fund and OpenOcean back in the syndicate rather than in front of it.

The good news is that the machines physical AI will live in are disproportionately ours. Europe builds the robots, the drones, the cars and the industrial equipment this processor is designed for – Seibel’s personal cheque draws a straight line from Quantum Systems’ drones to the silicon underneath them, and Exein’s $270M raise to secure those same machines shows the stack filling in. Imagine if the chips inside Europe’s machines were as European as the machines themselves.

What to watch is concrete: the UB410 tape-out, the 2027 evaluation units, and who leads the round that follows them. The opportunity is clear – physical AI will be built into hardware Europe already makes. Let’s keep its processor on this side of the Atlantic!
