Founded in 2016 by visionary entrepreneur and hands-on DJ Yianni Moutopoulos, One Round Entertainment was created with a mission to simplify the booking process and deliver exceptional entertainment experiences. With a background in robotic engineering and a passion for music, Yianni built the company on innovation, professionalism and a commitment to excellence, establishing One Round Entertainment as a trusted name within the events industry.
In 2021, Yianni expanded his vision with the launch of One Sound Audio Visual, providing complete production solutions including professional audio, lighting, staging, trussing, LED screens, projection mapping, special effects and party hire for weddings, corporate events, birthdays, music festivals, expos and more.
In 2025, Yianni’s wife, Natalie Moutopoulos, joined the family business as Co-Director, marking an exciting new chapter of growth. Together, they continue to elevate the standard of entertainment and event production, delivering unforgettable experiences backed by innovation, creativity and exceptional service.
