Fabio-Massimo Querrioux is the Founder and CEO of Aeternus Power. Born in Brussels and raised across Belgium, Switzerland, the United Arab Emirates, and Spain, he brings a genuinely international outlook to the company and is fluent in English, Italian, French, and Spanish.
Fabio-Massimo built his foundation in clean energy in residential solar sales in the United States, selling with Nusun Power across multiple sales teams in Florida and Puerto Rico. Over the 2025–2026 season he contributed to more than 500 residential solar sales in Puerto Rico alone, helping homeowners switch to clean, reliable power with no upfront cost, no debt, and no lien on their home.
That hands-on experience — seeing how a fragmented, hard-to-compare market left both customers and quality installers underserved — led him to found Aeternus Power: an independent, asset-light energy company that connects customers with a vetted network of installers across Spain and Türkiye.
A competitive sailor, swimmer, skier, and tennis player, he brings the discipline, teamwork, and goal-orientation of sport to building Aeternus Power.
