In this episode of DeepTech Unleashed, host Christian Noske sits down with Rhona Togher, the CEO and co-founder of Lios. Based in Dublin, Lios is on a mission to reduce noise pollution and prevent hearing damage through advanced material science. Rhona and her co-founder, Eimear O'Carroll, have developed SoundBounce, an award-winning acoustic material that is thinner, lighter, and significantly more effective at dampening low-frequency noise than traditional solutions. From its origins as a school science project to winning the European Patent Office’s Invention of the Year 2023, Rhona shares the remarkable story of Lios’s growth. The conversation explores the challenges of building a hardware powerhouse in a risk-averse industry, the importance of long-term customer relationships, and the unique dynamics of a co-founder partnership that began in high school.
