Treble, a sound simulation and synthetic audio data generation technology company, has raised €11m in a Series A round. The round was led by KOMPAS VC, an early-stage VC firm focused on the built environment with participation from Iceland’s leading venture capital firm Frumtak Ventures, the European Investment Bank, Omega Venture Partners, strategic partners St. Gobain & L-Acoustics, as well as experienced angel investors. The investment will be used to expand the Treble team, enhance R&D efforts, forge new enterprise clients, and tap into new markets.

Designing sound for buildings, cars and tech products has traditionally been an expensive undertaking because of a lack of easy-to-use and accurate simulation solutions that can be integrated into the design process. When buildings or products fail to meet the necessary acoustic standards, adjustments can be time-consuming and costly. The World Health Organization has stated that noise is the second most harmful environmental stressor affecting human health. With the rapid growth of AI-based audio models in voice technology, generative AI and augmented reality, the lack of audio training data has become a major bottleneck.

Treble was founded in 2020 by acoustic engineers Dr Finnur Pind and Jesper Pedersen. After close to a decade of researching sound simulation technology, the team launched the Treble platform in 2023, the world’s first cloud-based sound simulation and synthetic audio data generation platform. Powered by the company’s proprietary simulation technology, which has been benchmarked to be more than 100x faster than existing sound simulation solutions, it enables a wide range of industries to bring down costs and realize better sounding environments, products and services. Within a year since launch, Treble is being used by some of the largest and most prestigious companies in the world within tech, buildings, audio and automotive, including three of the five leading global tech giants and the world’s largest engineering consulting firms.

Dr Finnur Pind, Founder & CEO, Treble said: “The world could sound so much better than what it currently does. Our mission at Treble is to provide the software tools necessary to make the world a better sounding and less noisy place. This, in turn, will significantly improve health, well-being and productivity across the globe, and enhance people’s abilities to connect with one another. This Series A funding marks a significant moment for Treble, affirming our role as leading innovators within the audio space. Together with our partners and customers, we’re now set to expand our impact, bringing superior audio solutions to users everywhere as we develop the future of sound, create more resonant spaces and deeper audio engagements.”

Commenting on the investment, Sebastian Peck, Partner, KOMPAS, added: “Our investment in Treble reflects our commitment to creating a built environment that is both healthy and sustainable. We firmly believe Treble is leading the way to a better-sounding world with its innovative technology which opens up a whole new way of prototyping and testing products. There is a very large addressable market and I’m excited to see Treble and their phenomenal team continue to make waves.”
