Iceland’s Treble Raises $18 Million to Expand Voice AI Simulation Platform
Treble simulates realistic acoustic conditions and generates synthetic audio data for voice AI, wearables and robotics. The Icelandic startup has raised over $40 million, with Paladin Capital Group leading its September 2026 round; Amazon and Logitech are customers.
Treble, an Iceland-based acoustic simulation startup, has raised $18 million in an extension of its Series A funding round, the company announced in September 2026. The round was led by Paladin Capital Group, with participation from existing investors KOMPAS VC, Frumtak Ventures, EIC, and Omega ehf.
Combined with a $12 million investment received in 2024, Treble has now raised over $40 million in total. The company counts Amazon and Logitech among its customers.
Treble was founded in 2020 by acoustic engineers Finnur Pind and Jesper Pedersen. Its platform serves voice AI model developers, AI wearable makers, and robotics companies by providing simulation-based testing and synthetic data generation. Use cases include speech enhancement, noise suppression, model training, and virtual prototyping for hardware such as headphones, smart speakers, and smart glasses.
Earlier in 2026, Treble partnered with Hugging Face to launch a benchmark for speech recognition models tested across different realistic acoustic conditions.
“Audio AI is really a data challenge, and this is where the most opportunities to enable next-generation models and hardware lie,” said co-founder Finnur Pind. “We believe that accurate physics simulation can be an alternative way to create data for sound.”
Pind also highlighted interest in next-generation hearing devices. “I’m really excited about the next generation of these devices like headphones and smart glasses that can enable superhuman hearing — that’s an area where you can really just hear better in challenging acoustic environments,” he said.
Treble plans to expand further into physical AI applications, including robotics, automotive, and drone companies. Francois Ruether, VP of Paladin Capital Group, said the platform’s value is tied to the growing number of products that depend on sound. “As more products depend on understanding sound, this infrastructure becomes increasingly valuable across voice AI, wearables, robotics, and physical AI,” Ruether said.
