HyLight raises €13M to move to 15 inspection airships in 2027
HyLight has raised €13 million from Rubio Impact Ventures, DRW and Teampact Ventures, with Y Combinator and Ring Capital. The French start-up, founded in 2022 and based in Brétigny-sur-Orge, aims to go from four airships operated today to 15 HyLighters simultaneously in 2027. The funding round finances the industrialisation of the fleet, automated data analysis and the recruitment of 50 people. HyLight cites Germany and the Netherlands as priority markets in Europe.
The figures for the funding round and the fleet
HyLight claims more than 750 flight hours and thousands of kilometres inspected in France and Europe. HyLight names five customers: Enedis, NaTran, Téréga, SNCF Réseau and VINCI. The value of the contracts and the number of missions carried out for each are not public. The split between demonstration flights and recurring inspections is not specified. HyLight announces a €13 million funding round. Rubio Impact Ventures, DRW, Teampact Ventures, Y Combinator and Ring Capital are participating in the round. HyLight states that its new production workshop is operational. The workshop's exact capacity is not detailed. HyLight is targeting 15 HyLighters simultaneously in 2027.
An integrated model versus helicopters
HyLight designs, manufactures and operates its airships. The company also develops the software that turns flight data into diagnostics. The HyLighter is 12 metres long. It is electrically powered by hydrogen. HyLight announces up to 10 hours of flight, a target distance of 350 kilometres and a payload of 10 kg of sensors, including LiDAR, cameras and methane detectors. Imagery is provided at 1 mm/pixel at an altitude of 25 metres, with a LiDAR density above 1,000 points per square metre. HyLight states that the aircraft flies beyond the remote pilot's line of sight over critical infrastructure, in rural, peri-urban and urban environments, after authorisation by the DGAC and EASA. The terms of this authorisation are not public. HyLight describes autonomous airships.
Martin Bocken, co-founder and CEO, says: “Most power lines are still inspected by helicopter, as they were fifty years ago. Our HyLighters already do the same work, with greater precision and less risk.”
HyLight highlights low noise, the absence of direct emissions and availability. Helicopters remain the dominant solution for inspecting networks, despite high costs, emissions that can reach one tonne of CO2 equivalent per flight hour, noise and limited availability. Drones have shorter endurance. Satellites lack precision for some defects. Ground sensors cover a localised area. HyLight announces a long-endurance platform with heavy sensors. The HyLighter's hourly cost and a quantified comparison with one hour of helicopter flight are not public. Economic competitiveness is not publicly quantified.
The inspection offering for network operators
For electricity, gas and rail network operators, the offering becomes a recurring inspection service, with data collection and analysis. HyLight states that its tools automatically identify and geolocate more than 50 types of defects and vegetation-related risks on power networks. Repeated flights are intended to feed a digital twin of the infrastructure and the areas covered. HyLight cites insurance, agriculture and public land management as future applications. These applications are not operational.
For competitors, the pressure falls on helicopter missions dedicated to linear inspection. Helicopter operators retain missions that require a human presence, winching or rapid intervention. HyLight does not specify whether it covers these cases. Drone service providers keep short-duration flights, complex areas and detailed inspections. HyLight positions itself on long linear assets, with a sensor payload greater than that of standard drones. Buyers gain an alternative to test on defined sections. These buyers must check the authorisation conditions, team availability and data processing chain. No user feedback on diagnostic quality is public.
The limits of production and the business model
The 750 flight hours, the thousands of kilometres inspected and the five customers are figures claimed by HyLight. No signed contract, no revenue and no mission price are public. HyLight mentions DGAC and EASA authorisation. The document is not public. The exact conditions for beyond-visual-line-of-sight flight, the authorised areas and the operational limitations are not detailed. The production of 15 aircraft in 2027 depends on the workshop, recruitment and the hydrogen supply chain. The number of production sites and the manufacturing rate are not specified.
The question of the business model remains open. HyLight wants to sell a recurring service, with software and analysis. The choice between capacity rental, a flat rate per kilometre inspected or a subscription is not public. Operators comparing with helicopters need the full cost per mission, including team transport, hydrogen, maintenance and data processing. These figures are not public. HyLight states that the new factory is online. The target of 15 HyLighters simultaneously in 2027 is set. Profitability per mission is not public.
