HyLight raises €13m with US backing to scale European inspection airships

France’s HyLight has raised €13 million to expand its fleet of autonomous hydrogen-powered airships, bringing US investors into a financing round aimed at scaling infrastructure inspection across Europe. Rubio Impact Ventures, DRW and Teampact Ventures participated alongside existing investors Y Combinator and Ring Capital.

The funding will support aircraft production, automated analysis of inspection data and commercial expansion, with Germany and the Netherlands identified as priority markets. HyLight aims to move from four aircraft today to as many as 15 operating simultaneously in 2027, and plans to recruit 50 employees.

For now, the transatlantic connection is financial rather than operational. The supplied reporting identifies no US office, customer deployment or market-entry timetable. DRW’s participation and Y Combinator’s continued backing link the business to American capital, but the announced deployment strategy remains European.

Competing with helicopters

HyLight designs, manufactures and operates its own aircraft while developing software to interpret the data they collect. Its HyLighters have inspected thousands of kilometres of infrastructure in France and flown in several European countries. Operators using its services include Enedis, NaTran, Téréga, VINCI and SNCF Réseau.

The immediate competitive target is helicopter-based inspection of power lines, pipelines and railways. These missions require operators to survey long corridors while collecting detailed information about equipment condition, vegetation and potential leaks. HyLight is positioning its aircraft as a lower-noise, lower-risk alternative capable of replacing existing missions rather than simply adding another monitoring tool.

“Most power lines are still inspected by helicopter, just as they were fifty years ago. Our HyLighters already do the same job, with greater precision and less risk. This funding takes us from four aircraft to a fleet,” co-founder and chief executive Martin Bocken said.

Bocken told Tech Funding News that all contracts to date had been paid. That distinction matters for an industrial startup: the expansion is being built on commercial inspection work, not only demonstrations or unpaid trials.

Long endurance, detailed inspection

The 12-metre HyLighter uses helium for lift and a hydrogen fuel cell to power its electric motors, according to Tech Funding News. It can fly for up to ten hours, with no direct emissions and very low noise levels. Its stated target range is 350 kilometres.

Each aircraft can carry up to 10 kilograms of sensors, including LiDAR, cameras and methane detectors. HyLight reports imaging resolution of one millimetre per pixel at an altitude of 25 metres. The combination of endurance and detailed sensing is its answer to the trade-offs between shorter-range drones, satellite imagery and localised ground sensors.

According to EU-Startups, the aircraft have authorisation from France’s civil aviation authority, DGAC, and the European Union Aviation Safety Agency for beyond-visual-line-of-sight flights over critical infrastructure in rural, suburban and urban environments. Those European permissions should not be read as evidence of US operating approval.

Scaling the aircraft and the data business

HyLight’s software automatically identifies and geolocates more than 50 types of defects and vegetation-related risks across power networks, according to the funding announcement. The aim is to give maintenance teams information they can act on rather than thousands of raw inspection images.

Over time, the company intends to use repeated flights to build continuously updated digital representations of infrastructure and surrounding territory. Insurance, agriculture and public land management are potential future applications, rather than established revenue streams identified in the reporting.

A new production facility is already online, and HyLight is bringing more strategic component manufacturing in-house. Planned hiring spans engineering, AI and data, operations, regulatory affairs and business development.

The round follows a €3.7 million seed financing reported in April 2024, bringing reported funding to approximately €16.7 million. HyLight also participated in Y Combinator’s summer 2023 batch. Its next test is to turn that financing and European operating record into a larger fleet and repeatable commercial expansion—not, on the evidence available, a US launch.
