Lightsonic, a software company utilizing fiber optic sensing technology, has raised €3.3 million in seed funding to develop monitoring solutions for critical infrastructure. The investment, led by Maki.vc and supported by RAISE Ventures and Sondo, will help the company advance its real-time monitoring systems, which aim to detect leaks and threats in water, gas, and telecom networks, as well as energy grids and subsea assets. The funding will be used to accelerate product development and expand the team, with a focus on scaling the technology for broader commercial use. The company’s approach to leveraging existing fiber optic networks for infrastructure monitoring is expected to improve efficiency, security, and sustainability in vital sectors.

Based in the UK & Norway, Lightsonic’s innovative technology leverages existing fiber optic networks to provide real-time, high-resolution monitoring of infrastructure such as water and gas transmission lines, telecom networks, energy grids and subsea assets. By transforming fiber optic cables into advanced sensing systems, Lightsonic delivers scalable, cost-effective, and highly accurate solutions for detecting leaks and threats, preventing failures, and improving operational efficiency.

“At Maki.vc, we back deep-tech companies that redefine industries, and Lightsonic’s approach to fiber optic sensing is a game-changer for critical infrastructure monitoring. We are excited to support their journey in bringing this technology to the global market,” said Paavo Räisänen, Partner at Maki.vc.

RAISE Ventures echoed this enthusiasm, highlighting the impact of Lightsonic’s solutions on sustainability and security.

“The pressure on infrastructure is higher than ever, and the need for Lightsonic’s scalable technology has never been clearer. Their proactive monitoring of large networks—like water, gas, and cable—can significantly reduce environmental impact and operational risks. We are thrilled to back an incredible team redefining resilient infrastructure.” said Nicolas Chow, Principal at Raise Ventures.

Kjetil Holmefjord from Sondo emphasized the scalability of Lightsonic’s solutions, stating,

“Lightsonic’s fiber optic sensing technology has the potential to revolutionize how we safe guard critical assets. Their team has the expertise and vision to make a lasting impact, and we are proud to support them at this early stage.”

Lightsonic will use the funding to accelerate product development, expand its team, and scale its technology for commercial deployment.

“This investment marks a significant milestone in our mission to enhance the safety, sustainability, and efficiency of critical infrastructure worldwide. We are grateful for the trust and support of our investors as we bring our cutting-edge fiber optic sensing solutions to market,” said Tommy Langnes Co-Founder and CEO of Lightsonic.
