Viktor Lizunov
Market Development Manager I Co-Founder
Growing up by the sea in Dubrovnik, Croatia, Viktor Lizunov has spent much of his life on boats, gaining extensive hands-on maritime experience as a sailor, including service in the navy. Years of navigating the Mediterranean, particularly along the Adriatic coast, provided him with firsthand insight into the challenges and risks of anchoring, where sudden weather changes and powerful Bura winds can quickly create dangerous situations.
Recognising the need for a more reliable and intelligent anchoring solution, Viktor became a driving force behind the development of ARGUS AnchorTag, helping transform a long-standing maritime challenge into an innovative technological solution.
Fluent in five languages, Viktor has also built a successful career in sales, marketing, and investor relations. By combining his maritime expertise with strong commercial and business development skills, he plays a key role in bringing innovative maritime technologies to market and building strategic partnerships across the industry.
