About TONEO

TONEO is more than just a name. It’s a reflection of our purpose.

Born from the fusion of “tone” and “neo,” it reflects the heart of what we do: bringing new approaches to enhancing sound performance.

The Meaning Behind TONEO

“Tone” stands for the essence of audio: the character, clarity, and nuance that define every listening experience. “Neo,” meaning new, signals our forward-thinking spirit and commitment to innovation.

Brought together, TONEO reflects our mission to bring a new standard to sound performance through advanced material solutions. Rooted in deep material expertise and backed by decades of engineering tradition through Meneta, it’s where tradition meets innovation, and where every tone is shaped for the future.

Kim Oestergaard

Group CEO

Our CEO, Kim Oestergaard, has a background in the audio industry dating back to the early 2000s, and he is, privately, a passionate audiophile with a keen ear for musical instruments and vocals. This combination of professional experience and genuine passion helped spark our entry into the audio segment and the development of both SmartStack™ and TONEO, together with the invaluable contributions of his colleagues.

Kim has a strong conviction about the capabilities of our product line for the audio industry, built on years of empirical data from the automotive segment, where Meneta has positioned itself as a leading, first-mover supplier of damping materials for new cars. In this field, Meneta has grown its market share from around 10% to more than 45%. On this foundation, we are now expanding into new industries and segments – including, but not limited to, the audio industry. Kim recently put it this way:

“We have the financial strength, the R&D laboratory, the skilled staff, and the technical know-how to move into other industries. The audio industry is particularly interesting, as we can draw on our engineering and R&D departments, staffed by exceptionally talented acoustics specialists in their respective fields. Combined with our simulation capabilities and patented production technologies, this allows us to offer the audio industry measurable – and audible – improvements in sound performance.

Ultimately, we all want to listen to music the way the musicians and composers intended it to sound.”
