Icelandic voice AI startup Treble raises $18M in Series A extension

Treble, an Icelandic voice AI startup founded in 2020 by acoustic engineers Finnur Pind and Jesper Pedersen, has raised $18 million in an extension of its Series A round. Paladin Capital Group led the round, with participation from existing investors KOMPAS VC, Frumtak Ventures, EIC, and Omega ehf. The company has now raised more than $40 million in total, after a $12 million investment in 2024.

Treble provides a synthetic data generation platform and model evaluation services for voice AI companies. The platform can be used for speech enhancement, noise suppression, and model training, and evaluates voice AI models under different conditions to provide feedback to labs. Earlier in 2026, Treble partnered with Hugging Face to launch a benchmark for speech recognition models across different realistic conditions.

On the hardware side, Treble works with headphone and speaker companies on virtual prototyping to help them understand how their products might sound, and tests how smart speakers understand commands based on positioning. The company has recently expanded into simulation testing for smart glasses and AI devices.

Co-founder Finnur Pind said audio AI is fundamentally a data challenge, and accurate physics simulation can serve as an alternative to recordings scraped from the internet. Treble plans to increase its focus in the physical AI space, including robotics, automotive, and drone companies, to enable sound-based functions through testing and simulation.
