Swiss entrepreneur Joël Iunius founded NexSwiss Sàrl in 2018, a company specializing in the development of innovative software and digital platforms. Driven by a passion for innovation and the tangible impact of technology, he created the CityTourPlayer, a platform that enables the creation of GPS-synchronized audio guides designed to turn public transport journeys into enhanced sightseeing experiences. Born in London, the concept has since expanded to more than a dozen cities and has received multiple awards. Today, his team is working on AI-powered tourist audio guide solutions, developing a smart, interactive audio map product for hotels and others. NexSwiss Sàrl is also developing a digital product passport solution, anticipating upcoming European legislation in this field. This technology already has practical applications, notably in the digital tracking of railway welds in Switzerland.
