Prisma Photonics has raised $30m to scale its AI-driven fibre sensing platform for power grid and security infrastructure.

The Israeli deep-tech company is transforming existing optical fibre into an infrastructure monitoring platform.

The closure of an oversubscribed $30m growth round brings its total capital raised to $80m.

The AI-driven hyper-scan fibre-sensing platform has already been deployed across thousands of kilometres of critical infrastructure worldwide. Among them are 15 tier-one transmission system operators in the USA and Europe.

By converting existing optical fibres into massive, real-time sensor networks, Prisma combines optical fibre sensing with proprietary AI to detect, classify and localise events with metre-level accuracy across hundreds of kilometres, whether it’s an intrusion at a secured perimeter, a congested power grid, a wildfire threat along a high-voltage power line, or protecting long remote boundaries. As the system processes more data from diverse deployments, its AI models continuously improve, creating a powerful network effect and long-term technology moat.

The raise should accelerate Prisma’s scale-up journey and growth in the USA and Europe and fuel its expansion into Latin America, where utilities are racing to integrate renewable energy while addressing aging transmission systems.

“Critical infrastructure everywhere is under strain, whether from security threats, extreme weather or the energy transition,” said Eran Inbar, CEO of Prisma Photonics. “Our AI capabilities allow us to translate raw optical fibre signals into actionable intelligence in real time. That means our technology can protect a military installation one day, and optimise renewable energy integration the next. This funding accelerates our mission to make the world’s infrastructure safer, smarter and more resilient.”

The round was led by Protego Ventures, with participation of Adara Ventures and the investment arm of a Latin America transmission operator, alongside continued support from Insight Partners, Chione Switzerland and Schneider Electric’s venture arm.

“Prisma Photonics has demonstrated exceptional innovation in transforming existing fibre infrastructure into powerful monitoring systems,” said Lee Moser, managing partner at Protego Ventures (www.protego.vc). “Their proven technology platform addresses critical needs across multiple infrastructure sectors, from physical security to grid resilience. We’re excited to support their expansion as they protect increasingly vital infrastructure worldwide.”

Alberto Echeverri, partner at Adara Ventures (www.adara.vc), added: “Prisma Photonics has already proven its value to US and European utilities. Now it’s poised to support operators in emerging markets where there is tremendous potential for advanced grid technologies. We are proud to support the team as they work to unlock new capacity, reduce risks and drive the energy transition forward.”

Founded in 2017 and headquartered in Tel Aviv with offices in the USA and Europe, Prisma Photonics (www.prismaphotonics.com) is led by a team with a track record in building and scaling deep-tech companies.
