French entrepreneur based between Europe and the US. Founder of IONA Drones, investor in deep tech, and writer on the intersection of technology and the physical world.
French entrepreneur with a background in strategy consulting and a degree from London Business School. After years advising companies on where the world was heading, Etienne decided to go build it himself.
He founded IONA Drones in London in October 2021 to tackle autonomous cargo delivery — building aircraft that carry 20kg payloads over 100–200km ranges with minimal human intervention.
IONA operates from its London headquarters and an Irish office in Shannon. Alongside IONA, Etienne runs ROMO Ventures — a holding, investment, and consultancy vehicle focused on autonomous systems and deep technology.
He also angel invests through UK-based syndicates, backing founders working on industrial and hard tech — the kind of problems where engineering depth matters more than hype cycles.
