Its robots perform blade maintenance and repairs faster than humans, leveraging AI software, and the company has collaborated with major players like GE, Vestas, Siemens Gamesa, and Enel, producing nearly 400,000 MWh of clean electricity and preventing 165,000 tonnes of carbon emissions since 2020. The $62 million oversubscribed financing round, co-led by new investors Activate Capital Partners and S2G Investments, included participation from Carbon Equity, Overlap Holdings, and existing investors Lightrock, Blume Equity, Metaplanet, Change Ventures, and Extantia Capital. This follows a $30 million round in 2023 and a €4 million EU Innovation Fund grant in 2024, bringing total funding to around $174.5M across 11 rounds. Funds will expand global operations to over 30 countries, scale robot manufacturing, accelerate R&D in AI automation, advanced robotics, predictive maintenance tools, and customer-facing software. The year prior to the round was record-breaking, with revenue nearly tripled and operations significantly expanded, positioning Aerones as the global leader in robotic wind turbine services amid rising energy transition demands.
