The round was led by Protego Ventures, with participation from Adara Ventures, the investment arm of a leading Latin American transmission operator, and continued support from Insight Partners, Chione Switzerland, and SE Ventures, Schneider Electric’s venture arm.
Prisma Photonics’ Hyper-Scan Fiber-Sensing platform is already deployed across thousands of kilometers of critical infrastructure, including 15 major transmission system operators in the U.S. and Europe. By turning ordinary optical fiber into a continuous, high-resolution monitoring system, the platform detects, classifies, and locates events - from intrusions to grid congestion and wildfire threats - with meter-level accuracy.
As Prisma Photonics expands in the U.S. and Europe, the new capital will also fuel its entry into Latin America.
