Market Development Manager

Growing up by the sea in Dubrovnik, Croatia, I have spent my life on boats, gaining extensive hands-on experience as a sailor, including service in the navy. Navigating the Mediterranean—particularly the Adriatic coast—has given me firsthand insight into the dangers of anchoring, where sudden weather changes and powerful Bura winds create serious challenges. The need for a reliable anchoring solution was clear, and now, with A R G U S AnchorTag, that solution is finally a reality.

Fluent in five languages, I have also built a strong career in sales, marketing, and investor relations, combining my deep maritime expertise with business acumen to bring innovative solutions to the industry.
