Lightsonic develops smart sensors for infrastructure
Startup Lightsonic has secured investment totalling €3.3 million. The company develops AI-powered smart sensors that enhance the performance of critical infrastructure. Venture capital firm Maki was a key investor in this funding round, alongside RAISEVentures and Sondo.
Rapid technological advances, climate change and increasing urbanisation are putting a strain on Europe’s infrastructure. Many systems do not meet current requirements. One prime example is the UK’s water networks. They lose more than 1 trillion litres of water through leaks every year.
Technology features
Startup company Lightsonic has found a way to modernise the region’s infrastructure. The British-Norwegian software developer offers smart sensor systems. Their features include:
- Lightsonic’s platform integrates with passive telecommunications systems.
- it does not require hardware upgrades to scale the system.
- the platform increases network efficiency, including in economic terms.
- the use of AI and machine learning enables continuous monitoring of critical infrastructure;
- the technology provides high resolution and improves overall network quality.
The startup’s intelligent sensor system can be used in water and gas infrastructure. It also improves the efficiency of telecoms and electricity networks, contributing to better service delivery.

Lightsonic’s solution is based on AI sensors that analyse reflected light signals from fibre optic cables. This approach can detect sound, vibration, and temperature changes. Artificial intelligence categorises the problem and helps find a solution without the need for physical reconfiguration. A self-learning software layer is sufficient. This gives utilities the ability to monitor the condition of infrastructure in real time. They can also respond quickly to potential failures.
About the company
Tommy Langnes, James Ramsey and Thomas Coleman founded Lightsonic in 2024. Headquartered in Kristiansand, Norway, with another office located in London. The Lightsonic team has extensive expertise in fibre optic sensor development and AI/ML solutions. This expertise has led to the development of a product that utilises innovation to improve industrial sectors.
Initially, co-founder Tommy Langnes developed a similar solution for the oil and gas sector. He then joined forces with other partners to expand the functionality of the platform. Lightsonic is now focusing on projects for the water and defence sectors. The platform quickly identifies leaks, diagnoses faults and minimises risks to infrastructure.
Lightsonic’s investments will be used to enhance the solution and expand the development team. The company’s immediate plans are to enable the commercial deployment of the platform. Lightsonic also intends to adapt its technology for use in more industries.
