Spanish optical networking startup iPronics has raised €20 million ($21m) in a Series A funding round.

The round was led by Triatomic Capital, with participation from Fine Structure Ventures (Fidelity Investments), Bosch Ventures, Amadeus Capital Partners, and Criteria Venture Tech.

In a statement, the company said the funds would support the deployment of its Optical Networking Engine (ONE) in AI data centers, enabling “fast, scalable, and high-bandwidth communication for energy-efficient AI.”

Founded in 2019 as a spinoff of Universitat Politècnica de València, iPronics is headquartered in Valencia, Spain, and developed its ONE solution to overcome the bandwidth limitations of traditional electronic switches in AI data centers.

The start-up claims the optically switched fabric offered by its ONE solution provides 1000x faster reconfiguration when compared to other optic-based approaches, in addition to lossless operation, lower cost-per-port, and higher reliability due to its solid-state chip design.

"iPronics technology will enable larger GPU domains with fast optical interconnects, increasing training compute capacity and providing low latency inference,” CEO Christian Dupont said. “This investment will accelerate our Optical Circuit Switch market deployment, allowing customers to build next-gen AI infrastructure.”
