For more than ten years, I’ve been driven by one idea — the future of Space and Defense depends on the people behind it. My career began in technical recruitment, where I had the privilege to hire engineers designing cutting-edge systems for aerospace and advanced manufacturing.

Co-founding Demexios was a natural next step: a way to transform my industry knowledge and relationships into a dedicated structure that helps clients recruit faster, smarter, and with strategic alignment.
Over time, I built long-term partnerships with companies leading technological sovereignty — from NewSpace startups developing electric propulsion to defense integrators modernizing tactical and surveillance systems. These collaborations allowed me to form a powerful network of decision-makers, project leaders, and experts who now trust Demexios to deliver when precision truly matters.
Today, my role is not just to connect candidates and companies — it’s to ensure that every hire strengthens our clients projects.
