Treble Raises $18M for Voice AI Simulation

Iceland-based startup Treble has raised $18 million in a Series A extension led by Paladin Capital Group, bringing its total funding to over $40 million. The company, founded in 2020 by acoustic engineers, offers a simulation platform serving voice AI developers, hardware makers, and robotics companies, with Amazon and Logitech among its customers. Treble's platform generates synthetic audio data for model training, evaluates voice AI in varied conditions, and supports virtual hardware prototyping. The company is expanding into smart glasses, wearables, automotive, and drone sectors, betting that physics-based sound simulation will replace internet-scraped audio data for next-generation AI development.
