About HyLight HyLight’s mission is to help society become more resilient to climate change by improving the observation and inspection of infrastructure.

We build HyLighters, airships that collect data across vast distances with zero emissions.

Our Activities Include

• Detecting methane leaks from gas infrastructures (4% of global GHG emissions)
• Inspecting power lines to prevent outages and wildfires

By 2030, we aim to become the global leader in aerial monitoring.

In just 3 years, we have pushed the realm of possibilities: as we have:

• Developed 8 iterations of the HyLighter
• Logged over 300 flight hours
• Secured our first inspection contracts with Europe’s largest infrastructure operators
• Joined the world’s top startup accelerator, Y Combinator
• Raised €6 millions

HyLight is aiming for a diverse and included team, if your profile doesn't fit all the description but you can bring a diverse point of view, push it forward, it will be highly appreciated.
