Iceland-based Treble raises $18M for voice simulation platform used by AI developers and hardware makers

Treble, an Iceland-based startup founded in 2020 by acoustic engineers Finnur Pind and Jesper Pedersen, raised $18 million in a Series A extension led by Paladin Capital Group. Existing investors KOMPAS VC, Frumtak Ventures, EIC, and Omega ehf also participated. The company’s total funding now exceeds $40 million, including a $12 million investment in 2024.

The startup’s platform targets voice AI model developers, AI wearable manufacturers, and robotics companies by offering synthetic data generation for speech enhancement, noise suppression, and model training. It also evaluates voice AI models under varied acoustic conditions to provide performance feedback.

Treble has partnered with Hugging Face to launch a benchmark for speech recognition models across realistic conditions, emphasizing the role of accurate physics simulation in generating high-quality audio data.

Beyond model training, Treble supports hardware design and virtual prototyping for headphone, speaker, and smart glass manufacturers. Its tools help companies assess how products like smart speakers or AI wearables perform in real-world acoustic environments.

The company is expanding its focus to include robotics, automotive, and drone sectors, aiming to enable sound-based functions through simulation and testing. Paladin Capital Group’s Francois Ruether highlighted the platform’s role as a shared infrastructure layer for simulation-native acoustic development across multiple industries.
