Company Overview
About Prisma Photonics
Prisma Photonics is an Israeli deep technology company founded in 2017 by Yotam Levy, Yoav Peled, and Ronen Dar, headquartered in Tel Aviv, Israel. The company commercializes distributed fiber optic sensing (DFOS) technology that converts existing optical fiber cables — deployed by telecommunications companies in power grids, pipelines, railways, and perimeter security — into continuous, distributed sensors. Rather than deploying discrete point sensors at specific locations, Prisma's technology uses the fiber cable itself as a sensing medium: laser pulses are sent along the fiber and backscattered light is analyzed to detect, locate, and classify physical disturbances (vibrations, strain, temperature changes) along the entire cable length with meter-level spatial resolution.
Business Model & Competitive Advantage
Prisma Photonics' core innovation is the combination of its proprietary interrogator hardware (the unit that sends and receives laser pulses) with advanced machine learning algorithms trained on large datasets of physical events. This allows the system to classify detected events — distinguishing between benign activities (vehicle traffic, wind-induced cable vibration) and actionable threats (digging near a pipeline, unauthorized intrusion near a power line, train anomalies) with low false-positive rates. The platform's SaaS layer provides real-time alerts, historical event analytics, and integration with SCADA and utility operations center systems. Crucially, Prisma leverages fiber infrastructure that utilities already own, avoiding the need to install new sensor hardware and dramatically reducing deployment cost and timeline.
Competitive Landscape 2025–2026
Prisma Photonics has raised over $21M in funding from Main Sequence Ventures, ABB Technology Ventures (ABB is a leading power grid equipment company), Qualcomm Ventures, and other investors — a mix that validates both the technology and its strategic relevance to utility operators. The company targets power utilities, oil and gas pipeline operators, and railway operators globally, helping them meet regulatory requirements for infrastructure monitoring, reduce outage risk, accelerate fault detection, and support renewable energy integration goals that require higher grid reliability.
