HyLight, the French startup specializing in aerial inspection of critical infrastructure using autonomous hydrogen-powered airships, has raised EUR13 million from Rubio Impact Ventures, DRW and Teampact Ventures, joined by existing investors Y Combinator and Ring Capital.

In four years, its HyLighters have inspected thousands of kilometers across France, flown in several European countries and begun replacing helicopter missions for major infrastructure operators, according to a company press release. “The new funding will now enable HyLight to scale: industrializing its fleet, strengthening its automated data analysis capabilities and deploying a new data infrastructure across Europe to help monitor and protect critical networks and territories,” it continued.
