Prisma Photonics, a start-up based in Tel Aviv, has secured $30 million in an oversubscribed growth round led by Protego Ventures, with participation from Adara Ventures and the investment arm of a major Latin American transmission operator. Existing investors Insight Partners, Chione Switzerland, and SE Ventures (Schneider Electric’s venture arm) also joined the round, bringing the company’s total funding to $80 million.
The new capital will accelerate Prisma Photonics’ global expansion and strengthen deployments of its AI-driven Hyper-Scan Fiber-Sensing™ platform, which transforms existing optical fibers into distributed sensing networks for real-time monitoring of power grids, energy infrastructure, and secured perimeters. The company’s system has already been deployed across thousands of kilometers by 15 Tier-1 transmission operators in the U.S. and Europe, detecting intrusions, wildfires, and line faults with meter-level precision. Expansion into Latin America will target utilities integrating renewables into aging grid systems.
The platform combines advanced photonics with machine learning to identify and localize physical disturbances over hundreds of kilometers of fiber. The more the system operates, the more its AI models improve, reinforcing its performance through data network effects.
• $30M growth round led by Protego Ventures; total funding now $80M
• Strategic participation from Adara Ventures, Schneider Electric’s SE Ventures, and a Latin American grid operator
• Deployed with 15 Tier-1 transmission system operators in the U.S. and Europe
• Hyper-Scan Fiber-Sensing™ uses existing optical fiber to detect events with meter-level accuracy
• Targeting expanded deployments in North America, Europe, and Latin America
“Critical infrastructure everywhere is under strain—whether from security threats, extreme weather, or the energy transition,” said Dr. Eran Inbar, CEO of Prisma Photonics. “Our AI capabilities allow us to translate raw optical fiber signals into actionable intelligence in real time. This funding accelerates our mission to make the world’s infrastructure safer, smarter, and more resilient.”
🌐 Analysis: Prisma Photonics’ $30M raise underscores growing investor confidence in distributed fiber sensing as a scalable platform for grid intelligence and infrastructure protection. Similar efforts by companies like OptaSense (now part of Luna Innovations) and NEC’s distributed acoustic sensing systems show increasing convergence between optical communications and real-time environmental monitoring. Prisma’s strong utility footprint and expanding AI models could position it as a key enabler of resilient power networks and critical-asset security.
