From local workshop to global business
Our story begins in 1947 with the founding of AG für Elektroakustik in Zurich, Switzerland. What started as a small family business has grown into the purpose-led company Sonova is today, driven by the belief that hearing plays a vital role in people’s lives.
The founding story
A defining moment came in 1965, when Andy Rihs took over the family business together with his brother Hans-Ueli Rihs and close friend Beda Diethelm. With entrepreneurial spirit and a long-term perspective, they set the company on a path of growth and helped shape what Sonova would become. They were guided by a clear vision: A world where everyone enjoys the delight of hearing and can live a life without limitations.
This vision continues to guide us today. It is reflected in our purpose and culture, shaped by a strong belief in people: because progress is only possible through the dedication, expertise and care of those who make it happen.
“A company is nothing without its dedicated people.”
