€13m · Other round · Transportation · Brétigny-sur-Orge, France
Brétigny-sur-Orge-based HyLight, which operates hydrogen-powered airships for inspecting critical infrastructure, has raised €13m in financing from Rubio Impact Ventures, DRW and Teampact Ventures, with returning participation from Y Combinator and Ring Capital. HyLight says the capital will industrialise its fleet, strengthen automated data analysis and support expansion across Europe.
Private Equity Magazine reports that the package is split equally between equity and debt. It says the proceeds are intended in equal parts for R&D, higher aircraft production and commercial development, first in Europe and later in the US.
Scaling inspection means scaling aircraft and analysis together
The 12-metre HyLighter is designed for long, low-speed missions above power lines, pipelines and railways. According to HyLight’s announcement, the hydrogen-electric aircraft can fly for up to ten hours, targets a 350-kilometre range and carries as much as 10 kg of cameras, LiDAR and methane-detection equipment. The company says its software then turns those observations into geolocated defects and vegetation risks that maintenance teams can act on.
That combination matters commercially because infrastructure operators are not buying an aircraft alone. They need a repeatable inspection service: enough flight capacity to cover long networks, data precise enough to identify a problem and analysis that directs maintenance crews to the right location. More aircraft therefore create value only if HyLight can keep them available and process the resulting data without slowing delivery.
HyLight says it has completed more than 750 flight hours and thousands of kilometres of inspections for Enedis, NaTran, Téréga, SNCF Réseau and VINCI. It currently operates four aircraft and aims to have 15 working simultaneously in 2027. Private Equity Magazine reports that a new 1,300-square-metre factory south of Paris is producing one aircraft a month. That turns this round into a capacity test across manufacturing, flight operations and software rather than a simple hardware ramp.
Enterprise adoption is an operating milestone
In a 5 October interview, co-founder Martin Bocken told the Région Île-de-France that the company’s early difficulties included aviation regulation and the long decision cycles of major infrastructure customers. He also said customers had moved beyond tests to larger repeat requests. Those claims suggest that regulatory clearance and customer trust are part of HyLight’s product: the fleet must perform inside networks that cannot pause while a supplier learns.
The round gives HyLight room to widen coverage, but its most useful milestone will be whether 15 aircraft can produce consistent, actionable inspections across several countries. Germany and the Netherlands are the first named expansion markets. The operating model will scale when aircraft utilisation, analysis capacity and enterprise approvals advance together.
