Investment: “Treble raises nearly €15 million”
Treble, a Reykjavík-based sound simulation and synthetic acoustic data company, has raised approximately €15 million in a Series A-2 round led by Paladin Capital Group.
The round included participation from existing backers KOMPAS VC, Frumtak Ventures and the European Innovation Council (EIC) Fund. In September 2024 Treble announced an €11 million Series A led by KOMPAS VC; the fresh capital brings the company’s total funding to €36 million.
Founded in early 2020 by acoustic engineers Dr. Finnur Pind and Jesper Pedersen in Reykjavík, Treble has built a cloud-based platform that models how sound behaves physically in real-world spaces and uses physics-based simulation to generate synthetic audio datasets and create digital twins of rooms, vehicle cabins, devices and other acoustic environments.
The company positions its simulation as a faster, cheaper alternative to gathering physical audio recordings, enabling engineering teams to evaluate a product’s audio performance and generate labelled training data before building prototypes. Treble says its physics-based approach yields datasets that stand up to the same engineering scrutiny as real-world measurements, and it already works with major consumer and industrial technology firms including Amazon and Logitech.
The funding will be used to deepen Treble’s push into physical AI and world models — systems designed to perceive and act within physical environments — and to support the company’s expansion into the US market as it aims to make its simulation and synthetic data platform core infrastructure for the emerging physical AI and robotics industry.
“AI models and devices that perform well in a laboratory can struggle when they encounter reverberation, background noise, or an unfamiliar physical environment. Treble gives development teams at the world’s leading device makers a faster and more scalable way to model those conditions, generate the data they need, and test products to ensure they work reliably in the environments where machines operate, and people interact with them.” — Dr. Finnur Pind, co-founder and CEO of Treble.
