Treble

Treble simulates the acoustic physics of real rooms in the cloud, producing digital twins and labelled synthetic audio that let engineers test how a device will hear before anyone builds it. Founded in Reykjavik in 2020 by the acoustic engineers Finnur Pind and Jesper Pedersen, it counts Amazon and Logitech among its users. A Series A-2 of roughly EUR 15 million led by Paladin Capital Group in September 2026, with the European Innovation Council Fund taking part, brought total funding to EUR 36 million and pointed the company at physical AI and world models.
