Ubitium Raises $14M to Develop a Universal AI Processor
German semiconductor startup Ubitium has raised $14 million in seed funding to develop a reconfigurable processor designed to combine functions typically handled by separate chips. The financing will support the company's effort to bring its universal processor architecture to market for artificial intelligence applications in drones, robots and other autonomous systems.
The round was led by Ibex Investors, with participation from OpenOcean, existing investors KBC Focus Fund, Runa Capital and Inflection, and Florian Seibel, co-founder and co-CEO of defence technology company Quantum Systems. The latest investment brings Ubitium's total seed funding to $18 million since its founding in 2024.
Headquartered in Düsseldorf, Ubitium is developing hardware for physical AI—systems that process information from their surroundings, make decisions and control physical actions in real time.
One Processor for Multiple Computing Tasks
Autonomous machines commonly rely on several specialised processors. Digital signal processors handle sensor data, neural processing units accelerate AI inference, and central processing units manage general computing and control.
Ubitium aims to consolidate these functions into a single reconfigurable architecture. Its design uses programmable processing elements that can allocate computing resources to different tasks as workloads change. The company says this approach can reduce data transfers between chips, simplify software integration and lower hardware complexity.
The architecture combines unified memory with standard RISC-V development tools, allowing developers to use an established software ecosystem rather than rely entirely on a proprietary toolchain.
First Silicon Demonstrates the Architecture
Ubitium's first chip, the UB108, contains 256 processing elements and was manufactured using Samsung's 8-nanometre process. The company says the chip has demonstrated signal processing, AI inference and real-time control running on the same processor architecture.
The next step is the UB410, a planned commercial processor featuring 4,096 processing elements. Ubitium intends to complete its tape-out and deliver evaluation units in 2027.
Initial applications will focus on demanding sensing workloads, including high-resolution radar and audio systems. These applications require rapid processing of incoming signals alongside AI-based analysis. Drones and other autonomous machines are among the longer-term targets for the company's broader computing architecture.
Funding Supports Commercial Development
The new investment will help Ubitium advance its technology from working silicon toward commercial products. The company is targeting applications in which computing performance, power consumption, system weight and real-time response are important constraints.
For autonomous machines, consolidating multiple processing functions could reduce the complexity of integrating separate chips. However, the commercial value will depend on real-world performance, power efficiency, software compatibility and manufacturers' willingness to adopt a new processor architecture.
Ubitium has demonstrated its initial design, but its commercial processor remains under development. The planned 2027 evaluation units will be an important step in determining how effectively the architecture performs in customer applications.
