Prisma Photonics Raises $30M to Scale AI-Driven Fiber Sensing Platform
TEL AVIV, Israel, Oct. 16, 2025 — Prisma Photonics, a deep-tech company adapting existing optical fiber into an advanced infrastructure monitoring platform, closed a $30 million growth round. The financing brings the company's raised total to $80 million, and will accelerate Prisma Photonics' scale-up journey and growth in the U.S. and Europe. The company is additionally aiming to expand into Latin America.
Prisma Photonics' AI-driven Hyper-Scan Fiber-Sensing platform has already been deployed across thousands of kilometers of critical infrastructure worldwide. Among the deployments are 15 Tier-1 transmission system operators in the U.S. and Europe.
By converting existing optical fibers into massive, real-time sensor networks, Prisma Photonics combines advanced optical fiber sensing with proprietary AI to detect, classify, and localize events with meter-level accuracy across hundreds of kilometers and continuously improve its models as it processes more data. The technology is able to recognize intrusions at a secured perimeter, congested power grids, wildfire threats along a high-voltage power line, and protect long remote boundaries, the company said.
“Our AI capabilities allow us to translate raw optical fiber signals into actionable intelligence in real time. That means our technology can protect a military installation one day, and optimize renewable energy integration the next,” said Eran Inbar, CEO of Prisma Photonics.
